Struggling with High Forward Voltage Drop at 60V Schottkys? We have the Solution!

data sheet sms560-3g

SMS560-3G is a 5A/60V Schottky offering a forward voltage drop which was only possible with 40V types up to now. It has less than 0.55V at 5A, and anyway, unlike other "low Vf" Schottky types a low reverse current of maximum 80µA at 60V.

This outstanding performance is realized by Diotec's 3rd generation chip technology. Compared to former generations, this is a reduction of almost 20% in forward drop and thus power losses. Junction temperature is further reduced by the thermally low resistive MELF package, where these parts are build in.

The SMS560-3G is ideal for polarity protection but also high power output rectification. The 40V type SMS540-3G with even lower Vf completes the product family.

Enhance Efficiency of your Design and Save Board Space at the Same Time

data sheet ER2DSMA

With the ER2DSMA, a 2A/200V Superfast Efficient Rectifier in SMA package designers can easily solve two of their typical challenges: Reducing board space on one side, and increasing power output on the other.

This high power density device features a forward voltage of less than 1V and a reverse recovery time below 35ns. This makes it ideally suited for switching frequencies in the 100kHz range. The device has similar performance compared to alternatives offered by other manufacturers in the bigger SMB package.

It is available both in commercial and Automotive grade (suffix -AQ), and is well suited for applications like high frequency inverters, DC/DC converters, freewheeling diodes and LED drivers.


  • Average Forward Current 2 A
  • Forward Voltage < 1.0 V
  • Reverse Recovery Time < 35ns
  • SMA Package
  • Repetitive Peak Reverse voltage 200 V
  • Leakage Current 5 µA
  • AEC-Q101 grade available

Application Note ESD Protection Solutions

Our new Application Note ESD Protection Solutions introduces several so-called "lead-less" package outlines. Rather than having extended leads, these parts are connected on the bottom side and thus save valuable board space. Just one example out of several is the DI5315-02F in the very small SOT-883 or DFN1006-3 package.

It measures only 1.0mm by 0.6mm and offers two ESD protection diodes with common ground connection. They can protect high speed data lines and I/O ports, such as USB and HDMI interfaces, used at communication and entertainment devices.

Application Note about ESD Protection

Diotec offers a wide range of ESD protection diodes both in single line and dual line configurations in various packages ranging from general-purpose (SOD-323) to small-size 0201 packages, supporting a wide range of signal speeds. They can provide transient protection for data lines and I/O ports as per IEC 61000-4-2 (air and contact discharge).

New: Schottky in MiniMelf offers 2A of forward current at reduced reverse leakage

data sheet SGL2-40-3G

The SGL2-40-3G is a 2A/40V Schottky in the small yet powerful MiniMelf package. It uses the 3rd Generation chip technology offering a forward voltage drop of less than 530mV at 2A and a reverse leakage of below 40µA at 40V. Thus these parts are ideally suited for baterry charging circuits, where a high forward current is required for fast charging and low reverse leakage for a low discharging rate.

Further applications include the output rectification in AC/DC and DC/DC converters, polarity protection and free-wheeling diodes. The advantages of the MiniMelf case outline (DO-213AA) over lead-frame versions are explained in this short video.

New: 3A Rectifier Bridge in KBP Package

data sheet kbp302g

The KBP302G...KBP310G series of bridge rectifiers are offered in the small inline package KBP with 4mm pitch. The devices can be operated free-standing for up to 1.8A of output current as well as clipped onto a heatsink for up to 3A.

Forward surge current rating is 65A at 50Hz/10ms half sine wave pulse, the reverse voltage Vrrm ranges from 200V to 1000V. With a case length of 14.5mm and a thickness of 3.5mm it can be used even in tight assemblies where space is restricted.

TPSMA6L Series - Discover our new 600W TVS in a Flat SMA package

data sheet TPSMA6L

Diotec introduces the new 600W transient voltage suppressors TPSMA6L in a Flat SMA Package, featuring a typical height of 1.3mm only. It features a peak pulse power of 600W at 10/1000µs pulse form. Reverse stand-off voltage ranges from 5.0V to 85V.

The TPSMA6L are a cost effective solution having the same level of peak pulse power like the bigger P6SMBJ series. The flat SMA version offers a foot print size reduction of around 33% when compared to the SMB package and 45% less height when compared to both SMA and SMB packages.

Features and benefits are:

  • High power density
  • Smaller dimensions and low height profile package for space saving
  • Pad layout compatible with SMA packages

Parts are typically used in these applications:

  • Over-voltage protection
  • ESD protection
  • Free-wheeling diodes

New: 2A/1000V SMD bridge in slim SO-DIL package

data sheet B500S2A-SLIM

Diotec completes its family of 2A SMD bridges in the slim SO-DIL package. Up to now these parts were available with a maximum reverse voltage Vrrm of 800V, now the 1000V version B500S2A-SLIM is available.

It features best-in-class performance with an output current of up to 2.3A at 25mm² solder pad area and 25°C ambient temperature. Forward surge current rating is maximum 65A at 50Hz/10ms half sine wave pulse.

The parts come in the low profile SO-DIL package measuring only 2.5mm of body height. Thus they can be assembled on the bottom side of the PCB, where space is usually restricted. Application is input rectification for any kind of power supplies, especially where higher current output is required.
