ABS05-G

Overview

The ABS05-G is a surface-mount glass-passivated single-phase 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 50 V. The device has a typical thermal resistance (junction-to-ambient) of 50 °C/W and operates within a temperature range of -55 °C to +150 °C. Physical dimensions are approximately 6.40 mm in length, 4.60 mm in width, and 1.59 mm in height. The component utilizes lead-tin plated copper terminals and weighs 0.08 grams.

Feature Summary

• Glass passivation provides protection against mechanical stress and environmental contamination.
• Molded polarity symbol on the body ensures correct orientation during assembly.
• Suitable for any mounting position on printed circuit boards.

Applications

• Surface-mount applications on printed circuit boards.
• General-purpose rectification in low-voltage power supplies.
• AC to DC conversion circuits requiring compact form factors.

Procurement Notes

Verify the specific voltage rating required for the application, as the ABS series includes variants ranging from 50 V to 1000 V. Confirm that the 1.0 A current rating aligns with the load requirements. Ensure compliance with RoHS directives if applicable to the manufacturing process. Check for UL recognition file E349301 if safety certification is mandated for the end product.

Selection Notes

Select this component when a small footprint is necessary for high-reliability rectification. The 50 V rating makes it suitable for low-voltage AC inputs. Consider derating the forward current by 20% if used with capacitive loads. Verify that the operating ambient temperature remains within the specified -55 °C to +150 °C range to maintain performance.

Part Context

The ABS05-G belongs to the ABS series of surface-mount bridge rectifiers from Comchip Technology. This series covers ratings from 1.0 A to 10.0 A and voltages from 50 V to 1000 V. The ABS05-G specifically represents the entry-level voltage option within the 1.0 A current class, sharing the same physical ABS package dimensions as higher-rated counterparts like the ABS10-G.

Replacement Considerations

Direct substitutes must match the 1.0 A current, 50 V reverse voltage, and ABS surface-mount package. Verify pinout compatibility, as standard bridge rectifier configurations may vary between manufacturers. Ensure the replacement also offers glass passivation and similar thermal characteristics.
