This document describes the features and characteristics of TOSHIBA photocoupler models TLP3051 and TLP3052, including the structure of the photocoupler and gallium arsenide infrared emitting diode, rated voltage, current, and power parameters.
The Toshiba TLP3051 and TLP3052 are GaAs infrared LED‑driven photo‑triac optocouplers packaged in a six‑lead DIP. They are intended for office‑machine, household, and general electronics applications such as triac drivers and solid‑state relays.
The document provides maximum ratings, electrical characteristics, recommended operating conditions, pin configuration, and safety restrictions, including isolation voltage, forward current limits, and temperature ranges.
| Peak off‑state voltage | 600 V (min.) |
|---|---|
| On‑state current | 100 mA (max.) |
| Isolation voltage | 5000 Vrms (min.) |
| Forward current (IF) | 50 mA |
| Supply voltage (VAC) | up to 240 Vac |
| Weight | 0.44 g |
The devices are rated for a peak off‑state voltage of at least 600 V.
A minimum isolation voltage of 5000 Vrms is required.
Yes, they must not be used in safety‑critical or high‑reliability equipment such as medical, aerospace, or traffic‑signal devices.
