The document describes the Toshiba TLP250/D4 and TLP251/D4 series photocouplers, including the TLP250F and TLP251F variants that meet VDE0884 safety requirements. It outlines the purpose of the devices, their classification, and the applicable safety standards.
Key specifications such as input current, power dissipation, insulation resistance, creepage and clearance distances, and test voltages for both destructive and non‑destructive methods are listed. The manual also details the partial‑discharge measurement procedures and the VDE marking requirements for the products.
| Input current (Ip) | 100 mA |
|---|---|
| Output / Total Power Dissipation | 800 mW |
| Maximum operating temperature | 150 °C |
| Insulation resistance (500 V, 25 °C) | 102 Ω |
| Minimum creepage distance | 6.4 mm (TLP250) / 8.0 mm (TLP250F) |
| Minimum clearance distance | 6.4 mm (TLP250) / 8.0 mm (TLP250F) |
| Input‑to‑output test voltage, Method A | 945 V (TLPxxx) / 1710 V (TLPxxxF) |
| Input‑to‑output test voltage, Method B | 1180 V (TLPxxx) / 2140 V (TLPxxxF) |
| Highest permissible overvoltage | 4000 V (TLPxxx) / 6000 V (TLPxxxF) |
The maximum input current is 100 mA.
The minimum creepage distance is 6.4 mm for TLP250 and 8.0 mm for TLP250F; the minimum clearance distance is the same values.
Insulation resistance is 102 Ω measured at 500 V and 25 °C.
Method A test voltage is 945 V (type) or 1710 V (typeF); Method B is 1180 V (type) or 2140 V (typeF).
