Toshiba Launches High-Temperature Voltage-Driven Photorelays
KUALA LUMPUR, Feb 25 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has launched four voltage-driven photorelays, “TLP3407SRB”, “TLP3412SRB“, ”TLP3412SRHB“, and “TLP3412SRLB”, housed in the small S-VSON4T package.
According to Toshiba in a statement, volume shipments start today.
The new photorelays deliver a maximum operating temperature of 135 degrees Celsius (°C), up from 125°C in previous models, targeting automotive semiconductor testers, probe cards, and burn-in equipment that operate under high-temperature conditions.
Advances in electrification and autonomous driving have increased demand for high-density electronic component packaging in automotive equipment, requiring semiconductors and supporting devices to function reliably at elevated temperatures.
Toshiba said the temperature increase was achieved by optimising the design of built-in elements. The photorelays are voltage-driven with integrated resistors on the input side, eliminating the need for external resistors and reducing board space requirements.
The S-VSON4T package measures 1.45 × 2.0 millimetres (mm), enabling multiple photorelays to be mounted on a limited board area while maintaining reliable operation under high-temperature conditions.
Toshiba said the combination of compact size, high-temperature tolerance, and built-in resistor design makes these photorelays well-suited for automotive semiconductor testing and burn-in applications.
The company added that it will continue expanding its lineup of products capable of supporting high-temperature operation for automotive and industrial equipment.
