TLP113 is a photocoupler produced by Toshiba. It is suitable for surface mounting. Its features are low input current threshold, fast switching speed, TTL/LSTTL compatible, wide operating temperature range, high isolation voltage, and can be used in digital systems to achieve optical isolation.
The TLP113 is a small‑outline GaAs photocoupler designed for surface‑mount assembly. It combines a light‑emitting diode with a high‑gain, high‑speed photodetector that provides an open‑collector output and Schottky‑clamped transistor. The device is suitable for computer‑peripheral, microprocessor, and general electronics interfaces, supporting both A/D and D/A isolation.
Key electrical characteristics include a typical forward voltage of 1.80 V, isolation voltage of 2500 Vrms (min), supply voltage around 5 V, and propagation delays of about 60 ns. The part is rated for up to 20 mA forward current and 25 mA output current, with a recommended operating temperature range of –40 °C to 85 °C. Application notes cover switching‑time tests and common‑mode transient immunity.
