HDS20M-13

Overview

The HDS20M-13 is a single-phase standard recovery bridge rectifier manufactured by Diodes Incorporated. It features a 1000 V peak repetitive reverse voltage and a 2 A average rectified output current. The device utilizes an HDS surface-mount package with glass-passivated die construction. Key electrical characteristics include a maximum forward voltage of 0.95 V at 1 A, a leakage current of 5 μA at 25°C, and a non-repetitive peak forward surge current of 110 A for 1 ms pulses. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Glass passivated die construction provides robust mechanical strength and long-term reliability under thermal stress.
• Miniature HDS package design optimizes printed circuit board space utilization for compact electronics.
• Low leakage current and low forward voltage drop contribute to improved energy efficiency in power conversion circuits.

Applications

• AC to DC bridge full wave rectification for switch-mode power supplies (SMPS)
• LED lighting driver circuits
• Battery charger systems
• Home appliances and office equipment power stages
• Telecommunication applications

Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the tape and reel packaging format containing 3,000 units per carrier. Confirm that the component meets RoHS directives and halogen-free requirements as defined by the manufacturer's green product standards before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring high-voltage isolation up to 1000 V with moderate current handling capabilities. Ensure the application environment supports the specified operating temperature range and consider derating the continuous current by 20% if the load is capacitive to maintain safe junction temperatures.
