The Toshiba TLP265J(V4T7TR,E is a single-channel triac-output optocoupler in a 6-SOIC surface-mount package. It switches AC loads up to 600 V off-state with a maximum on-state RMS current of 70 mA, making it a fit for driving low-current triacs, solid-state relays, or directly switching small AC loads like solenoid valves and indicator lamps in industrial controls, appliance boards, and HVAC systems. The 3750Vrms isolation rating covers reinforced insulation requirements for line-voltage separation in equipment rated up to 300 V working voltage.
The 600 V off-state voltage rating gives headroom for 240 VAC nominal lines with margin for transients. The 500 V/µs typical static dV/dt immunity means the output won't falsely trigger on fast-rising mains noise or inductive load switching — a common failure point in older phototriac designs. Turn-on time is 20 µs, fast enough for phase-control and zero-cross switching cycles at 50/60 Hz. Hold current is 1 mA typical, so the triac latches cleanly once triggered and won't drop out on light loads.
Package and mounting
Housed in a 6-SOIC with 4 active leads (two LED side, two triac side) on a 4.40 mm body width. Surface-mount package suits reflow assembly; the SOP footprint is shared across the TLP265 family, so a board layout for the J variant accepts the other tape-and-reel suffixes.
Lifecycle and compliance
Listed as active with RoHS compliance. Approvals from CQC, cUR, UR, and VDE simplify acceptance in equipment destined for North American and European markets.
