Overview
The ABS8-G is a surface-mount glass-passivated bridge rectifier manufactured by Comchip Technology. It provides a maximum recurrent peak reverse voltage of 800 V and supports an average forward rectified current of 1.0 A at 25°C. The device features a peak forward surge current capability of 40 A under JEDEC testing conditions. Electrical characteristics include a maximum forward voltage of 1.1 V at 1.0 A DC and a typical thermal resistance from junction to ambient of 80 °C/W. The component operates within a temperature range of -55°C to +150°C and utilizes lead-tin plated copper terminals for mounting.
Feature Summary
- Glass passivation protects the junctions against mechanical stress and moisture.
- Designed specifically for printed circuit board mounting applications.
- Lead-free construction compliant with RoHS standards.
Applications
- General purpose AC to DC conversion in compact electronic devices.
- Power supply circuits requiring high reverse voltage blocking capabilities.
- Bridge rectification in consumer electronics and industrial control systems.
Procurement Notes
Verify the specific voltage rating matches the application requirements, as the ABS series spans multiple reverse voltage options. Confirm package dimensions align with the PCB layout, particularly the suggested pad design provided in the datasheet. Ensure compliance with environmental regulations such as RoHS if required by the end product specifications.
Selection Notes
Select the ABS8-G when an 800 V reverse voltage rating is necessary for the circuit design. Consider the 1.0 A continuous current limit and derating curves for higher ambient temperatures. Evaluate the thermal resistance parameters to ensure adequate heat dissipation without additional cooling mechanisms in the final assembly.
Part Context
The ABS8-G belongs to the ABS series of surface-mount bridge rectifiers from Comchip Technology. This family includes variants with reverse voltages ranging from 50 V to 1000 V, all sharing a common 1.0 A forward current rating. The series is characterized by its small form factor and glass passivation technology suitable for automated surface-mount assembly processes.
Replacement Considerations
Direct replacements must match the 800 V reverse voltage, 1.0 A forward current, and SMD package footprint. Verify that alternative components offer comparable thermal resistance and surge current ratings to maintain circuit reliability.
