Author: EIS Release Date: Jun 21, 2023


Toshiba has introduced a photo-relay in a 1.45 x 2mm package that switches on in 250μs – 50% quicker than its existing TLP3475S.

The new part, TLP3476S, is in a 1.5mm high (max) S-VSON4T package, has a maximum on-resistance of 1.5Ω, can carry 400mA (ac or dc) and isolates up to 500Vrms.

3mA is the maximum LED drive needed to operate the device (30mA abs max), and operation is across -40 to 110°C.


Applications are expected in semiconductor testers, probe cards and other instrumentation.
