Toshiba Electronics launches ultra-compact photocoupler for industrial applications operating to 125ºC

Offering guaranteed performance from -40ºC and 125ºC, the TLP2451 is supplied in an SO8 package with dimensions of just 3.95mm x 5.1mm x 2.5mm. Minimum isolation is rated at 3750Vrms and the photocoupler 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/µs.

The new coupler can operate with power supply voltages of 10V to 30V and has a maximum threshold input current of 5.0mA. Maximum propagation delay time is rated at 700ns.
