Ultrafast recovery - 1200 V diode

Main product characteristics

operation

– TO-220Ins

Capacitance = 7 pF

– TO-220FPAC

Capacitance = 12 pF

Description

The high quality design of this diode has

produced a device with low leakage current,

regularly reproducible characteristics and intrinsic

ruggedness. These characteristics make it ideal

for heavy duty applications that demand long term

reliability.

Such demanding applications include industrial

power supplies, motor control, and similar

mission-critical systems that require rectification

and freewheeling. These diodes also fit into

auxiliary functions such as snubber, bootstrap,

and demagnetization applications.

The improved performance in low leakage current,

and therefore thermal runaway guard band, is an

immediate competitive advantage for this device.
