DSA20C150PB

Diode Arrays Overview

The DSA20C150PB is a silicon Schottky diode manufactured by Littelfuse, formerly IXYS. It features a dual anode common cathode configuration housed in a TO-220-3 through-hole package. Key electrical parameters include a maximum repetitive reverse voltage (Vrrm) of 150 V and an average forward current (If) of 10 A per element. The device exhibits a typical forward voltage (Vf) of 730 mV and a maximum reverse leakage current (Ir) of 2 mA. It supports a non-repetitive peak forward surge current (Ifsm) of 220 A and operates within a junction temperature range of -55 °C to +150 °C, with a power dissipation rating of 65 W.

Diode Arrays Procurement Notes

Verify the manufacturer designation as Littelfuse, which acquired IXYS, when sourcing this component. Confirm the specific suffix PB corresponds to the tube packaging format rather than tape-and-reel variants. Ensure compatibility with TO-220-3 mounting holes and verify RoHS compliance status against the latest datasheet revision before integration into production designs.

Diode Arrays Selection Notes

Select this component for applications requiring moderate current handling with low forward voltage loss. The dual anode setup simplifies circuit topology compared to single diodes. Consider the 150 V voltage rating to ensure adequate margin above operating voltages. Evaluate thermal resistance requirements given the 65 W dissipation limit and the constraints of the TO-220-3 package in your specific enclosure environment.

Diode Arrays Part Context

This part belongs to the DSA20C series of high-performance Schottky rectifiers from Littelfuse/IXYS. The series is characterized by silicon carbide metal-silicon (SiC Schottky) technology, offering superior efficiency over standard p-n junction diodes. The DSA20C150PB specifically targets general-purpose power conversion needs where reliability and low noise are prioritized.

Diode Arrays Replacement Considerations

Cross-reference with other DSA20C series parts for different voltage ratings if system requirements change. Verify pinout compatibility with existing PCB footprints when substituting. Check thermal performance curves to ensure equivalent heat dissipation capabilities under similar load conditions.
