TGL200U08: Combined TVS and Ultrafast Diode save space in Flyback Converters
Flyback converters are the state-of-the-art choice for auxiliary power supplies, LED drivers and battery chargers. Their topology requires a special network, the so called snubber at the primary side, in order to protect the MOSFET respectively switching IC against excessive voltage spikes.
The snubber usually consists of a TVS diode and an Ultrafast rectifier; depending on switching frequency also a Fast or even Standard Recovery type might be used.
The TGL200U08 by Diotec combines a 200V TVS and a 800V Ultrafast diode in a single DO-213AB/Melf package. It thus helps to save board save in this usually rather tightly assembled circuits. Further available are the Fast Recovery version TGL200F08; a Standard Recovery version is under development.
