Toshiba Introduces Compact Photorelays with Improved Isolation Voltage of 3.75kV

03 May 2017

Toshiba America Electronic Components, Inc. (TAEC)* announced that it has expanded its extensive portfolio of photorelays with the addition of two 4-pin SO6 package products. The new TLP172AM and TLP172GM operate at temperatures up to 110°C, feature an isolation voltage of up to 3750Vrms and have a 3mA (max) trigger current. This makes them suitable for use as function switches in measuring equipment, sensor switches in security systems, power monitoring function in battery management systems, IoT equipment and more.

The new photorelays are halogen-free[1] and are made with a double mold structure. The TLP172AM and TLP172GM utilize multi-chip technology and were developed as high spec, pin-compatible versions of Toshiba's existing 2.54SOP package products (TLP172A, TLP172G). The new devices satisfy designers' requirements for thin packages that comply with high levels of safety standards.

Offering on/off control for high-current applications, the TLP172AM features a higher current output rating than phototransistor photocouplers. The TLP172GM can be used in space-constrained battery management systems.
