Toshiba Introduces New Lineup of High-Current Control Photorelays

August 3, 2016

Housed in Small Packages; Designed for Currents up to 4A

Lineup of High-Current Control Photorelays

IRVINE, Calif., -- Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the launch of a new lineup of high-current control photorelays. The TLP3106, TLP3107, TLP3109 and TLP3127 are designed for currents in the range of 1.7A to 4A and are housed in small, space-saving (2.54SOP4, 2.54SOP6) packages.

Targeting applications that handle relatively large currents, including programmable logic controllers (PLCs), battery management systems (BMSs) and factory automation inverters, the new photorelays utilize Toshiba’s latest generation trench MOSFETs. These MOSFETs are capable of controlling large currents at levels equivalent to those usually handled by mechanical relays1. When compared to mechanical relays, which have mechanical contacts, photorelays have the advantages of producing less noise and eliminating deterioration caused by contact wear.

The use of a 2.54SOP6 package (TLP3109) reduces mounting volume by approximately 40 percent and product height by approximately 50 percent, when compared to Toshiba’s products in DIP packages. The small size allows for mounting on the back surface of printed circuit boards and can contribute to smaller sets. Toshiba’s diverse lineup of photorelays includes products with terminal (blocking) voltages of up to 100V, making them suitable for use in various applications - including power line control.

Key Applications 

  • Programmable logic controllers (PLC)
  • Battery management systems (BMS)
  • Inverter motor torque protection
  • HVAC relay replacement
  • Test equipment
  • Security equipment
