1N4948 Description

Short technical summary and product information.

The Vishay Dale 1N4948 is a fast recovery rectifier diode designed for high-reliability applications. It offers a maximum peak inverse voltage of 1000V and a minimum breakdown voltage of 1100V at 50µA.

 

This diode can handle an average rectified current of 1A at 55°C without a heat sink, and up to 3A under MIL-STD-750 conditions. The maximum forward voltage is 1.3V at 1A, and the reverse current is a maximum of 200µA at 25°C and 1µA at 100°C at PIV. It has a capacitance of 15pF maximum at -12V and a surge current rating of 15A for 10-8 msec. surges.

 

The operating temperature range is -65°C to +175°C, with a storage temperature range of -65°C to +200°C. The component is housed in a Digi A case with alpha-numeric marking and a cathode band for polarity indication.

 

Available options include high-reliability screening (HR) per MIL-PRF-19500, JANTX level, and RoHS compliance by adding the '-PBF' suffix. Non-RoHS versions feature Sn/Pb plating.
