Toshiba TLP197GA Photocoupler Datasheet
The TLP197GA is a GaAs infrared emitting diode optically coupled to a photo‑MOSFET in a 6‑pin SOP package, intended for surface‑mount use and as a replacement for mechanical relays where space savings are needed. It is used in a variety of electronics such as computers, measuring equipment, and industrial robotics.
Key specifications include a peak off‑state voltage of 400 V, trigger LED current up to 3 mA, on‑state current of 120 mA, on‑state resistance of 35 Ω, and an isolation voltage of 1500 Vrms. Recommended operating conditions specify a supply voltage up to 320 V, forward current up to 25 mA, and an ambient temperature range of –20 °C to 65 °C.
