TLP628(GB,F) – Optocoupler – Toshiba

The Toshiba TLP628(GB,F) is a single-channel transistor-output optocoupler in a 4-pin DIP package, featuring a 350 V (min.) collector-emitter breakdown voltage and 5000 Vrms isolation. Available for RFQ from Pacific Component Xchange.

The Toshiba TLP628(GB,F) is a single-channel, transistor-output optocoupler (photocoupler) that pairs a gallium-arsenide infrared emitting diode with a high-voltage silicon phototransistor. The “GB” designation identifies the device’s current-transfer-ratio (CTR) rank, while the trailing “F” indicates the lead-free/RoHS-compliant packaging option. With a 350 V (min.) collector-emitter breakdown voltage and 5000 Vrms isolation, the TLP628 is widely used for signal isolation between high- and low-voltage circuits in industrial and telecom equipment.
