Key Features
Broad Voltage & Current Portfolio
- VRRM range: 4KV to 35KV – covers low, medium, and high voltage requirements
- IF(AV) options: 100mA – flexible for low-power to medium-power circuits
- One series replaces multiple discrete diodes, simplifying inventory and design
Ultra-Fast Recovery (TRR = 100ns)
- Reverse recovery time of 0.1μS (100ns) enables efficient high-frequency switching (>50kHz)
- Significantly reduces switching losses and reverse recovery dissipation
- Ideal for flyback, forward, and resonant converters operating at high voltage
Very Low Leakage Current
- IR = 2μA at 25°C
- Minimizes standby power consumption and heat generation
- Extends system lifetime in continuous high-voltage bias applications
High Surge Current Capability
- IFSM = 10A (single cycle) – excellent inrush current tolerance during power-up or fault events
- Robust against load transients and capacitor charging surges
Low Forward Voltage Drop
- VFM ranges from 13V to 50V depending on voltage rating and current
- Reduces conduction losses, especially in high-duty cycle rectifiers
High Junction Temperature (Tj = 120°C)
- Reliable operation in elevated ambient temperatures
- Suitable for sealed or poorly ventilated enclosures
Compact Axial Lead Package
- Uniform body size: φ4.2×15mm, lead φ0.8mm
- Easy drop-in replacement for standard high voltage axial diodes
- Compatible with automated insertion and wave soldering processes
Environmentally Compliant
- RoHS compliant, lead-free, and halogen-free epoxy molding
- Meets international environmental standards
