Toshiba TLX9 automotive coupler AEC Q101

Toshiba’s new photocouplers suit inverter control and intelligent power module (IPM) interface applications in conventional, EV and HEV applications.

The TLX9304, TLX9378 and TLX9376 integrate a GaAlAs infrared light emitting diode and high-gain, high-speed photodetectors. An internal Faraday shield provides a common-mode transient immunity of 15kV/μs. In the case of the TLX9175J photo-relay, the LED technology is based on a gallium arsenide construction. A high-voltage MOSFET between the relay’s output terminals meets the needs of battery control systems.
