Toshiba 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 3750 V_RMS, and have a 3 mA (max) trigger current.  They are excellent 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 photorelays are halogen-free and made with a double-mold structure. The TLP172AM and TLP172GM utilize multi-chip technology and they are a drop-in replacement upgrade from Toshiba's older products (TLP172A and TLP172G). The devices satisfy designers' requirements for thin packages that comply with the highest 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.
