Toshiba launches new photocoupler

TOKYO, JAPAN: Toshiba's semiconductor and storage products company announced a new addition to its line-up of gate-drive photocouplers for use in driving medium-power IGBTs and power MOSFETs.

The new 4A photocoupler TLP5214 is housed in a thin SO16L package and has protection features that prevent IGBTs from over-current conditions. Mass production shipments of the new product will start from the end of May.

TLP5214 integrates protection features, IGBT desaturation detection, active miller clamp and fault detection among them. Integrating these protection features, previously in external circuits, contribute to a lower overall system cost for detecting and handling malfunctions.

With the thin SO16L package, low height of 2.3mm (max), TLP5214 guarantees a creepage distance of 8mm, suiting it for applications requiring higher isolation specs.

Combined with Toshiba's original high-reliability infrared LED, TLP5214 is suitable for use in a 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 degrees Centigrade), making it possible to reduce dead time in the inverter circuit, which can secure higher operating efficiency.
