BYG20 Series: Ultrafast Avalanche SMD rectifier diode
Discover our BYG20 Series, which is an Ultrafast Avalanche SMD rectifier diode in SMA Package having repetitive reverse voltage of 200 V until 600 V and average forward current rating of 1.5 A. Having non-repetitive peak reverse avalanche capability of up to 20 mJ and a very low reverse recovery time of less than 75 ns, these devices are well suited for high-side floating gate driver circuits, as a bootstrap diode. For half-bridge gate drivers, adding an external bootstrap diode in parallel with the internal one, can significantly overcome the problem of excessive power losses in the driver IC. A stand-alone operation is of course possible as well.
Further typical applications include output rectification in high frequency power supplies and forward converters as well as freewheeling diodes in inverters for consumer, automotive and telecommunication circuits.
Features
- SMD Package DO-214AC/SMA
- Repetitive reverse voltage of 200 V to 600 V
- High average forward current of 1.5 A
- Reverse recovery time less than 75 ns
- Controlled Avalanche Characteristics: 20 mJ
ESD9BL24P: All-Around Protection by Diotec's ESD Diodes
Diotec’s ESD9BL24P is a 24V, 350W, bidirectional Electrostatic Discharge (ESD) protection diode in a tiny “leadless” SOD-882/DFN1006 package.
It offers optimum trade-off between low capacitance and higher ESD robustness. This device is designed to safely protect electronic components from ESD transient surges of up to +/-30 kV as per IEC610004-2 standard (air and contact discharge) without any compromise in its performance and reliability. Its low capacitance of 0.5 pF ensures very low distortion of data signals in high-speed communication systems.
Typical applications include data line and I/O port protection, portable electronic devices but also LED lighting modules. In addition, due to the tiny package outline of only 1.0 mm x 0.6 mm board space, it is suitable for battery operated compact, portable devices.
Features
- Peak Pulse Power Dissipation 350 W
- Peak Pulse Power current 6 A
- Miniature Case Outline SOD-882
- Low Junction Capacitance 0.5 pF
- Low Leakage Current
ABS15Y: a Low Profile 2000 V Bridge Rectifier in SMD
Today’s modern high power density electronics are more vulnerable to electrical stresses than ever due to the component miniaturization. High demand scalable electronics such as LED Street Lamps require high reliable circuit protection. These devices are connected directly to the land line,
where lightning strikes are a permanent source for excessive voltage surges. It requires a bridge rectifier with high safety margin and also slim package outline to fit into the compact electronics.
Discover our ABS15Y, a low profile, high power, standard bridge rectifier. It offers an impressive
reverse voltage of 2000V, an average forward current rating of 1.6 A/2.0 A (depending on pad size). It comes in an ABS package with only a height of just 1.4 mm. Thus they can be assembled on the bottom side of the PCB, where space is usually restricted. They are well suited for input rectification for applications like high voltage power supplies, LED Street Lighting Systems, 4G/5G Base Stations, Smart Meters and so on.
Features
- Repetitive peak reverse voltage of 2000 V
- Average Forward current of 1.6 A/2.0 A
- Ultra-low profile ABS package
- Just 1.4 mm of device height
- High creepage and clearance

SM3000: Outstanding Reliability and High Performance when Lightning Strikes
Designers of Smart Meters, LED Street Lamps, 4G/5G BaseStations, EV Charging Systems and similar applications often face the issue of over-voltage transients, since all these devices are connected directly to the land line which is highly affected by lightning strikes. They are affecting the reliability and lifetime of these products, so the use of rectifier diodes with extra high safety margin against transient surges is mandatory.
The SM3000 by Diotec is especially developed for these applications. It offers an impressive reverse voltage of 3000 V, an average forward current of 1 A and comes in a single SMD Melfpackage. Due to the large clearance and creepage it can replace the usual series connections, which are still common for input rectification at the above applications. You will find more detailed information in our actual flyer.
Features
- SMD Melf package
- Repetitive peak reverse voltage of 3000 V
- Average forward current of 1 A
- Replaces series connections
SKM14: Low Forward Voltage Drop. Small Size.
The SKM14 is a 1 A / 40 V Schottky diode offering a forward voltage drop of less than 0.35 V at 1 A. It comes in the compact SOD-123FL package and measures only 3.7 mm x 1.8 mm. The very low profile height of 1.0 mm makes it well suitable for any mobile, slim but yet high performing electronics. This device is optimized for battery powered systems, where high energy savings are desired, e. g. for LED headlights.
Its low junction capacitance makes the SKM14 further suited for high frequency, energy efficient applications. This includes battery chargers, offline power supplies, set-top boxes, smart meters, any kind of smart home devices, DC/DC converters and many more.
Features
- SOD-123FL package
- Repetitive peak reverse voltage 40 V
- Low forward voltage of < 0.35 V at 1A
- Ideal for battery powered applications
