Smart gate driver photocoupler released

A smart gate driver photocoupler, the TLP5214A, has been released by Toshiba for driving medium power insulated gate bipolar transistors (IGBTs) and power MOSFETs.

Features include desaturation leading edge blanking time, filtering time, and optimisation of soft turn-off performance. These are said to contribute to secure execution of applications by suppressing short-time pulse noise during switching and desaturation sensing.

Said to improve on the performance of the TLP5214, the device offers a DESAT leading edge blanking time of 1.1μs and a DESAT filter time of 90ns. According to the company, soft turn-off time of 7μs is double that of its predecessor.

The TLP5214A operates from a 15 to 30V supply and can deliver a peak output current of ±4.0A (Max). A propagation delay of 150ns with ±80ns skew is said to support use in high speed applications.

TLP5214A is housed in a SO16L package with a maximum height of 2.3mm, which the company claims meets the requirements of all major safety standards. Its isolation voltage is 5000V RMS and the minimum creepage/clearance distances is 8.0mm.

Applications including industrial inverters, solar energy inverters, air conditioner inverters and servo amplifiers.
