产品概述
描述
The STDES-DIS001V1 reference design allows you to evaluate silicon controlled rectifier TN4035HA as a discharge switch. It is suitable to discharge capacitance up to 3mF connected on 400 Vbus (800 V max.).
This active discharge can be controlled thanks to an insulated gate drive implemented with opto-transistors. Thanks to TN4035HA peak current capability, the discharge resistor can be reduce to 0.2 Ω in order to perform the discharge in few milliseconds.
2x TN4035HA are implemented on the reference design. One connected in High side and another connected on low side. The mid point of these SCRs can be used in order to diagnose that both SCRs are functional before discharge. Also the diagnostic can be done after discharge to verify the SCRs have not been damaged during the discharge.
Thanks to their excellent peak current rating TN4035HA are recommended for fast active discharge of EV high voltage power bus.
