BYG23T: Diotec's Avalanche Rated 1300V Bootstrap Diode
Discover our bootstrap diode BYG23T in SMA package, well suited for high-side floating gate driver circuits. The major challenge here is to select a robust device with respect to high voltage peaks during low side MOSFET or IGBT turn-off, as well as forward surge currents during re-charging of the storage capacitor. High frequency operation is state-of-the-art in these applications.
The BYG23T features an avalanche rating of 5mJ with breakdown voltage of 1350V and a very low reverse recovery time of 75ns. Repetitive peak forward current rating is 3A, and average forward current 1A.
Various half-bridge gate driver circuits are currently available in the market with integrated bootstrap diodes. The total power dissipation of such gate driver IC is the combination of gate driver losses and the internal bootstrap diode losses. The difficulty with this circuit is the operation at higher frequencies and load capacitance applications, where the power losses in the internal bootstrap diode dominates the overall power dissipation.
An external bootstrap diode, even if 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.

SBT1045-3G - An Excellent Choice for Output Rectification in LED Drivers
We are pleased to introduce the SBT1045-3G, the upcoming member of our 3rd generation Schottky family. It comes in a TO-220AC power package and features a repetitive peak reverse voltage of 45V with 10A of average forward current rating. It offers lower power losses both in forward and reverse and is dedicated for a high level of efficiency.
Typical applications include output rectification in DC/DC converters and power supplies, polarity protection and free-wheeling diodes. The SBT1045-3G is an excellent option for output rectification in LED drivers.
Here the main parameters of this part under typical application conditions of an output rectifier:
Vf typ 390mV at If = 10A and Tj = 125°C
Ir typ 10mA at Vr = 5V and Tj = 125°C
First samples are available from September; they can be ordered already now at our orderconfirmation.
New Series about 3rd Generation Schottky Technology Part 5/5: Products for Lighting Applications
Diotec's -3G Schottky Technology encompasses high power handling capability at small package outlines. It offers state-of-the-art performance in the field of Schottky Rectifiers. Reduced forward voltage Vf and low reverse leakage current Ir are two common features of all these new devices.
Lighting is an essential element in our present world. It plays a decisive role in our daily lives, right from low power indoor lighting at home, to mid and high power outdoor lighting, industrial and horticulture lighting systems. Lighting accounts for about 15% of global electricity consumption.
A new era came with the light emitting diodes (LED). They consume little electricity, are long lasting, versatile and contain no toxic substances. LEDs are the future for lighting. Other intelligent technologies such as digital lighting control systems and smart lighting solutions are emerging in the market, further ensuring an increase in efficiency, greater energy savings and thus lower the carbon emissions.
By choosing the best suited semiconductor components in the design, power losses decrease and energy savings can be pushed even further. Hence, the selection of the right components can also boost-up the overall performance.
We at Diotec Semiconductor focus on supplying high quality products like the 3rd generation Schottky diodes. Their features like low to very low Vf and lower leakage currents make them well suited for a variety of lighting applications like LED lamp drivers, lighting controls, polarity protection of automotive lighting systems and many more.
Our actual -3G Schottky portfolio includes rectifier diodes with (very) low forward voltage drop, reverse voltages from 20V to 45V and forward current ratings from 0.5A to 30A.
