TLP202A is a photocoupler launched by Toshiba. It adopts 8-pin SOP package and has higher output current, which is suitable for high current on/off control.
The TLP202A is a gallium‑arsenide infrared LED optically coupled to a photo‑MOSFET in an 8‑pin SOP package, designed for high‑current on/off control. It offers a normally‑open configuration with a peak off‑state voltage of 60 V and an on‑state current capability of up to 400 mA.
The document lists absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics such as forward voltage, isolation voltage, and switching times. It also includes restrictions on product use 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) |
| Forward voltage (IF=10 mA) | 1.0‑1.3 V (typ. 1.15 V) |
| Forward current (absolute max) | 50 mA |
| Supply voltage (recommended) | Up to 48 V |
The device can handle up to 400 mA of on‑state current.
The isolation voltage is specified as 1500 Vrms minimum.
The recommended supply voltage can be as high as 48 V.
Typical forward voltage is about 1.15 V (range 1.0‑1.3 V).
