Toshiba Corporation's (TOKYO:6502) Storage & Electronic
Devices Solutions Company today announced the launch of“TLP5214A,”
a new smart gate driver photocoupler for use in driving
medium-power IGBTs and power MOSFETs that delivers desaturation
sensing characteristics that improve on those offered by the
current “TLP5214”. Mass production shipments start today.

TLP5214A newly integrates such features as desaturation leading
edge blanking time, filtering time, and optimization of soft
turn-off performance. These contribute to secure execution of
applications by suppressing short-time pulse noise during switching
and desaturation sensing.
The latest Gartner market report recognizes Toshiba as the
leading manufacturer of optocouplers by sales in 2015 and 2016,
with 23% of sale-based market share in CY2016. (Source: Gartner
“Market Share: Semiconductor Devices and Applications Worldwide
2016” 30 March, 2016)
Toshiba will continue to deliver products that meet the needs of
customers by promoting the development of a diverse portfolio of
photocouplers and photorelays tailored to market trends.
