CDSER4448 Description

Short technical summary and product information.

The CDSER4448 is a general-purpose SMD switching diode manufactured by Comchip Technology. It is designed for high-speed switching applications with a maximum reverse recovery time of 9 ns. The diode is rated for a repetitive peak reverse voltage of 100 V and a maximum average forward current of 125 mA.

 

Electrical characteristics include a forward voltage of 0.72 V at 5 mA and 1 V at 100 mA. Reverse leakage current is limited to 25 nA at 20 V and 100 nA at 80 V. The device can handle a peak forward surge current of 1 A for a 1 µs pulse. Maximum power dissipation is 150 mW.

 

The diode is housed in a 0503 (1308 Metric) surface-mount package with a supplier device package of 0503/SOD-723F. Terminals are gold plated and solderable per MIL-STD-750, method 2026. Polarity is indicated by a cathode band. The component weighs approximately 0.002 g and can be mounted in any position. Operating, storage, and junction temperature range is up to 125 °C.
