TLP363JF – Photo TRIAC Coupler (Optocoupler) – Toshiba

The Toshiba TLP363JF is a zero-cross Photo TRIAC coupler (optocoupler) rated at 600 V peak off-state voltage with 5000 Vrms isolation in a 4-lead DIP4 (F-type) package. A hard-to-find part available by RFQ from Pacific Component Xchange.

The Toshiba TLP363JF is a zero-cross Photo TRIAC coupler (optocoupler) that combines a GaAs infrared emitting diode optically coupled to a photo-TRIAC detector with a built-in zero-voltage-crossing trigger circuit. It is designed to drive higher-power TRIACs and to switch AC loads cleanly at the zero-crossing point of the AC line, minimizing switching noise and inrush-related EMI. The device is housed in a compact 4-lead plastic DIP4 (F-type) package and provides robust 5000 Vrms input-to-output isolation.

Key Features

• Zero-cross Photo TRIAC coupler (GaAs IRED to photo-TRIAC output)
• Built-in zero-voltage-crossing trigger circuit for low-noise AC switching
• Peak off-state voltage (V_DRM): 600 V (min)
• Isolation voltage: 5000 V_rms (min)
• Trigger LED current (I_FT): 10 mA (max)
• On-state current: 100 mA (max)
• Creepage and clearance distance: 8.0 mm (min)
• Package: 4-lead plastic DIP4 (F-type), approx. 0.26 g

Applications

• TRIAC gate driver / trigger for higher-power TRIACs
• Solid-state relays (SSR)
• AC-output modules for programmable logic controllers
• Home appliance and white-goods AC load control
• Industrial control and temperature/heater control

Why Source TLP363JF from Pacific Component Xchange

The TLP363JF is an established Toshiba phototriac coupler with limited authorized-distributor availability, making it a genuinely hard-to-find part for repair, legacy production, and end-of-line builds. Pacific Component Xchange is an independent distributor specializing in obsolete and hard-to-find power-management ICs and optocouplers.
