TLP192A is a photocoupler/photorelay from Toshiba, packaged in a 6-pin SOP. It has higher output current rating than phototransistor-type photocouplers, and is suitable for use as On/Off control for high current.
The TLP192A is a gallium‑arsenide infrared emitting diode optically coupled to a photo‑MOSFET in a 6‑pin SOP package. It is a normally‑open photorelay designed for on/off control of high‑current loads.
The document lists absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics such as forward voltage, on‑state current, isolation voltage, and switching times, along with usage restrictions and safety notes for designers.
| Peak off‑state voltage | 60 V (min) |
|---|---|
| Trigger LED current | 3 mA (max) |
| On‑state current | 400 mA (max) |
| Isolation voltage | 1500 Vrms (min) |
The maximum on‑state current is 400 mA.
The device is rated for an isolation voltage of 1500 Vrms (minimum).
The recommended supply voltage is up to 48 V.
The forward voltage is typically 1.15 V, ranging from 1.0 V to 1.3 V.
