TLP200D is an optical coupler produced by Toshiba. It is packaged in 8-pin SOP and has 2 form A switch, which is suitable for replacing mechanical relays in many applications that require space savings.
The TLP200D is a GaAs infrared emitting diode optically coupled to a photo‑MOS FET in an 8‑pin SOP package. It functions as a 2‑form‑A switch suitable for replacing mechanical relays where space savings are required.
The document lists absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics such as forward voltage, on‑state resistance, isolation voltage, and switching times, along with safety and usage restrictions for designers.
| Peak off‑state voltage (Voff) | 200 V (min) |
|---|---|
| On‑state current (Ion) | 200 mA (max) |
| On‑state resistance (Ron) | 8 Ω (max) |
| Isolation voltage | 1500 Vrms (min) |
| Forward voltage (Vf) at 10 mA | 1.0‑1.3 V |
| Trigger LED current | 3 mA (max) |
| Input‑to‑output capacitance | 0.8 pF (typ.) |
The TLP200D can withstand a peak off‑state voltage of at least 200 V.
The isolation voltage is rated at a minimum of 1500 Vrms.
A supply voltage between 150 V and 200 V is recommended.
The typical forward voltage is between 1.0 V and 1.3 V.
