Ultra-compact photocoupler to address MOSFET needs

Toshiba Electronics has announced the TLP2451, a photocoupler designed for inverters, induction heating designs and other devices requiring safety isolation and operation at high ambient temperatures.

Offering guaranteed performance from -40 to +125C, the photocoupler is supplied in an SO8 package with dimensions of just 3.95 x 5.1 x 2.5mm.

Minimum isolation is rated at 3750Vrms and the device features a totem pole buffer logic output that can deliver peak output currents of +/-0.6A.

Toshiba's TLP2451 incorporates a GaAlAs infrared LED that is optically coupled to a high-gain, high-speed photodetector.

An internal Faraday shield provides a common mode transient immunity of +/-15kV/us.

The coupler can operate with power supply voltages of 10 to 30V and has a maximum threshold input current of 5mA.

Maximum propagation delay time is rated at 700ns.
