ABS20M

Bridge Rectifier Overview

The ABS20M is a 2A, 1000V standard bridge rectifier manufactured by Taiwan Semiconductor. It features a glass passivated chip junction and utilizes molded plastic construction for reliable low-cost performance. The device supports an average forward current of 2.0 A on aluminum substrates and handles a peak forward surge current of up to 50 A (8.3ms) or 110 A (1.0ms at 25°C). Key electrical parameters include a repetitive peak reverse voltage of 1000 V, a maximum junction temperature of 150°C, and a typical forward voltage of 1.02 V at 1A. It operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Procurement Notes

Verify the specific ordering code when purchasing. The standard ABS20M is supplied in tape and reel packaging with a quantity of 5,000 units. If automotive qualification is required, select the ABS20MH variant, which indicates AEC-Q101 compliance. Confirm package type ABS and marking codes match design requirements before integration.

Bridge Rectifier Selection Notes

Select the ABS20M for general-purpose rectification where 1000V blocking capability and 2A continuous current are sufficient. Consider the ABS20MH if the application demands AEC-Q101 automotive qualification. Ensure thermal management accounts for the 85°C/W junction-to-ambient resistance. Verify that the operating ambient temperature allows for proper current derating as specified in the datasheet curves.

Bridge Rectifier Part Context

This component belongs to Taiwan Semiconductor's ABS series of standard bridge rectifiers. The ABS package provides a compact form factor suitable for automated placement. The ABS20M specifically addresses high-voltage, medium-current applications requiring robust surge handling and standardized mounting configurations common in consumer and industrial electronics.

Bridge Rectifier Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Engineers must verify pinout compatibility, voltage/current ratings, and thermal characteristics when considering alternative manufacturers' components.
