TLP620,TLP620-2,TLP620-4 is a photocoupler produced by Toshiba, using a high-density packaging method, suitable for AC current input.
The TLP620 series are high‑density, GaAs infrared LED and silicon phototransistor optocouplers designed for AC input applications. Three variants are offered: the 4‑pin TLP620 (1 circuit), the 8‑pin TLP620‑2 (2 circuits), and the 16‑pin TLP620‑4 (4 circuits). Pin assignments and mechanical dimensions are listed for each package.
The datasheet details absolute maximum ratings, recommended operating conditions, switching performance, and safety approvals such as UL, BSI, SEMKO and VDE. Electrical parameters include collector‑emitter voltage, isolation voltage, forward current, and temperature ranges. This manual is written in Japanese.
