Toshiba Introduces New Series of Gate Drive Photocouplers

Press release date: Mar 01, 2017

Feature Low-Input Current Drive and Rail-to-Rail Output in a Low-Height, Wide Creepage Package

Toshiba America Electronic Components, Inc. (TAEC)* today announced the launch of a series of low-input current drive, rail-to-rail output, gate drive photocouplers: the TLP5771, TLP5772 and TLP5774. A threshold input current of 2mA (max), which is half of Toshiba's existing products[1], enables the new photocouplers to support bufferless direct drive of low- to medium-power IGBTs and MOSFETs by microcontrollers. The new parts are available in three levels of peak output currents: 1A, 2.5A and 4A.

The TLP5771, TLP5772 and TLP5774 were designed to meet a wide range of user requirements for applications including photovoltaic power conditioning systems, AC drives, compact motor drivers, industrial sewing machines, and industrial inverters. This series of Toshiba's IGBT/MOSFET-drive photocouplers provide a common-mode rejection (CMR) of 35kV/µs (min), making them suited to industrial applications that will be installed in electrically noisy environments.

Featuring rail-to-rail output, the new photocouplers help to reduce the power loss of both the photocoupler and the IGBT during switching, and also reduce the operation voltage to 10V (min) as compared to the 15V (min) of Toshiba's existing products. This can contribute to higher system efficiency. Additionally, a low-height (2.3mm, max) SO6L package allows the new photocouplers to contribute to the development of thinner, smaller systems.

Other features include:

  • Integrated infrared LED
  • High operating temperature rating: Topr max=110°C
  • Safety standard approved: UL 1577/cUL (CSA Component Acceptance Service No. 5A); EN 60747-5-5; EN 60065; EN 60950-; CQC (China Quality Certification Center)
