TLP281,TLP281-4 is a photocoupler produced by Toshiba,suitable for applications such as PCMCIA Fax modem,programmable controllers.
The Toshiba TLP281 and TLP281-4 are miniature surface‑mount GaAs optocouplers that combine an infrared LED with a phototransistor for electrical isolation.
They provide a collector‑emitter voltage of 80 V, forward current up to 50 mA, isolation voltage of 2500 Vrms, and operate from –55 °C to 100 °C. Pin configurations are 4‑pin for TLP281 and 16‑pin for TLP281‑4.
| Forward Current (IF) | 50 mA |
|---|---|
| Operating Temperature Range | -55 °C to 100 °C |
Pin 1 is ANODE, pin 2 is CATHODE, pin 3 is EMITTER, and pin 4 is COLLECTOR.
Lead soldering should be performed at 260 °C for about 10 seconds.
