(for medium-power IGBTs)
(for small-power IGBTs)
TLP118 / TLP554
The TLP557 drives the base of a GTR directly.
An external resistor, Rex, is connected between
pins 6 and 7. This resistor causes the base current
to become constant and stabilizes the GTR drive.
The TLP557 photo-IC coupler and two booster
transistors can drive a high-power GTR.
The TLP151, TLP351, TLP701, TLP705 and
TLP2541 high-speed photo-IC photocouplers can
drive a low-power IGBT directly.
