com PD-20376 HFA40HF120 HEXFRED Features • Reduced RFI and EMI • Reduced Snubbing • Extensive Characterization of Recovery Parameters • Hermetic • Surface Mount CATHODE ANODE TM Ultrafast, Soft Recovery Diode (ISOLATED BASE) VR = 1200V VF = 3.
1V Qrr = 510 nC di(rec)M/dt = 350A/µs Description HEXFRED diodes are optimized to reduce losses and EMI/RFI in high frequency power conditioning systems.
An extensive characterization of the recovery behavior for different values of current, temperature and di/dt simplifies the calculations of losses in the operating conditions.
The softness of the recovery eliminates the need for a snubber in most applications.
