High Temperature / High Voltage Schottky Diodes for Industrial and Automotive Applications
The MBRS20200CT and MBR20200CT from Diotec are high temperature Schottky diodes featuring a very low reverse leakage current. Parts are offered in both D²PAK (S) and TO-220AB containing two diodes in common cathode configuration. They feature an average forward current rating of 2 x 10 A and Vrrm of 200 V. These devices are optimized for high temperature operation in industrial and automotive applications, requiring a maximum junction temperature of 175°C.
Applications include switch mode power supplies and battery chargers, where high frequency operation comes along with voltage outputs of 24 V or even 48 V. Parallel operation for high current outputs is possible when parts are assembled tightly on the same heatsink. The very low leakage current of each part ensures high stability against thermal runaway, compared to conventional 150°C Schottky barrier diodes. And their low forward voltage drop enables low power losses and thus high efficiency operation.

Want to do automatic assembly of the Bridge Rectifier to the PCB as well? Here is the solution! S16MSD2 - Half Bridge in D²PAK allows for full PCB assembled Power Rectifier Stages
When it comes to power bridge rectifiers, design engineers have to go back to through-hole devices which first need to be soldered onto the PCB, and then screwed to an extra heat-sink. These are manual assembly steps, which cost time and effort and also bear the risk of potential failures.
Other power semiconductors such as MOSFETs or IGBTs and diodes for the PFC, converter and inverter stage or brake chopper, are widely available in SMD outlines like the well known D²PAK. They can be assembled fully automatic by pick&place machines and afterwards solder process, at high speed and with constant quality.
The S16MSD2 half bridge closes the gap which was up to now at the input rectifier stage. Two of these parts form a full bridge, which can be assembled in the same process step than the other power semiconductors. Like for those, cooling is done via the PCB metallization. So the entire power stage can be done in one time and with the same concept.

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

Need to Protect Your Sensitive Design and Space is Limited? Check Our Tiny Lead-less Packages!
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.
New: Schottky in MiniMelf offers 2A of forward current at reduced reverse leakage
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.
