Toshiba International announces a new addition to its line-up of gate-drive photocouplers for use in driving medium-power IGBTs and power MOSFETs.
Introduced by Toshiba Corporation’s Semiconductor & Storage Products Company, the new 4A output smart gate driver photocoupler TLP5214 is housed in a thin SO16L package and has protection features that prevent IGBTs from over-current conditions.
The TLP5214 integrates multiple protection features, IGBT desaturation detection, active miller clamp and fault detection, contributing to a lower overall system cost for detecting and handling malfunctions.
The thin SO16L package, despite its low height of 2.3mm (max), guarantees a creepage distance of 8mm, making the TLP5214 photocoupler suitable for applications requiring higher isolation specs.
Combined with Toshiba’s original high-reliability infrared LED, the TLP5214 photocouplers are suitable for use in a wide range of applications, including those that require high thermo-stability, such as factory automation, home photovoltaic power systems and UPS.
A maximum propagation delay time of 150ns and propagation delay skew of ±80ns are guaranteed within the defined operation temperature range (up to 110°C), making it possible to reduce dead time in the inverter circuit, and allowing higher operating efficiency.
