TLP748J DIP-6 SCR Output Optoisolator

Description

TLP748J DIP-6 SCR Output Optoisolator The TLP748J is a high-performance photocoupler featuring an infrared emitting diode (IRED) optically coupled to a photo-thyristor. Encased in a compact six-lead plastic Dual In-line Package (DIP-6), this device is engineered for applications requiring reliable electrical isolation and AC load switching. With a peak OFF-state voltage of 600 V, a maximum trigger LED current of 10 mA, and an ON-state current capacity of up to 150 mA, the TLP748J ensures robust performance. It boasts an isolation voltage of 4000 Vrms, making it ideal for safety-critical environments. Suitable for office machines, household equipment, solid state relays, and switching power supplies.
