ABS4-G

Overview

The ABS4-G is a single-phase, surface-mount glass-passivated bridge rectifier manufactured by Comchip Technology. It features a maximum average forward rectified current of 1.0 A and a maximum recurrent peak reverse voltage of 400 V. The device supports a peak forward surge current of 400 A under an 8.3 ms single half-sine-wave test condition. Electrical characteristics include a maximum forward voltage of 1.1 V at 1.0 A DC and a maximum DC reverse current of 5.0 µA at rated blocking voltage (25°C). The component operates within a temperature range of -55°C to +150°C and utilizes a lead-tin plated copper construction.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• Surface-mount design suitable for printed circuit board mounting
• Lead-free compliant with tin-plated copper terminals

Applications

• General purpose AC to DC conversion in compact electronic devices
• Power supply circuits requiring surface-mount bridge rectification
• Adapters and chargers utilizing standard PCB layouts

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement orders. Confirm that the reel packaging quantity matches the required production volume, as standard reels contain 5,000 pieces. Ensure storage conditions adhere to the specified temperature ranges to maintain component integrity prior to assembly.

Selection Notes

Select the ABS4-G when a 400 V peak reverse voltage rating is required for AC input lines. This component is appropriate for applications demanding a 1.0 A continuous forward current capability in a small surface-mount footprint. Consider the thermal resistance and derating curves if the operating ambient temperature exceeds 25°C or if high surge currents are expected during startup.

Part Context

The ABS4-G belongs to the ABS series of SMD glass-passivated bridge rectifiers from Comchip Technology. This family includes variants ranging from ABS05-G to ABS10-G, offering reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 1.0 A forward current rating. The series is designed for space-constrained applications requiring reliable AC-to-DC conversion on printed circuit boards.

Replacement Considerations

Cross-reference with other SMD bridge rectifiers in the DO-214AA (SMB) package type that meet 400 V PRV and 1.0 A IAV specifications. Verify pinout compatibility and physical dimensions against the suggested pad layout provided in the datasheet to ensure mechanical fit.
