Toshiba Photorelay in Ultra-Compact S-VSON4T
High‑temperature photorelay with 1A switching and ultra‑compact package for advanced test and measurement systems
The Toshiba TLP3407SRB is a voltage‑driven photorelay designed for high‑density, high‑temperature test and measurement applications.
Rated for operation up to 135°C and offering up to 1A ON‑state current, it enables reliable switching in thermally demanding environments. Integrated input resistors eliminate external components, while the ultra‑small S‑VSON4T package maximises PCB space efficiency.
Related TLP3412 variants offer low ON‑resistance and fast switching for signal applications.
