VRM = 200 V, IF = 5 A, 10 A, 15 A Fast Recovery Diode Built-in Temperature Detection
FMKS Series
Data Sheet
Description
The FMKS Series is the fast recovery diode built-in temperature detection.
A fast recovery diode and a Schottky barrier diode for temperature detection are formed on the same die. Thus, the FMKS Series achieves highly accurate temperature detection that is higher than that with a thermistor, component reduction, power supply downsizing, and easy attachment.
Features
● Built-in temperature detection ● Highly accurate temperature detection of FRD ● Component reduction of temperature detection ● High speed switching ● Low forward voltage drop
