FEATURES
■ Replaces two diodes of the bridge in steady
state
■ Dual unidirectional switches in a single
package
■ Inrush current limitation circuit for off-line
power supply
■ Designed for instantaneous response after AC
line drop out or browning
■ Surge current capability as per IEC61000-4-5
BENEFITS
■ Low consumption (I_Pt= 20mA)
■ High noise immunity:
dV/dt> 1000V/µs @ Tj=125°C
■ Low reverse current losses
■ Integrated pilot driver of the power switches
■ Suitable where efficiency and space are critical
