A7

Overview

The Good-Ark Semiconductor A7 is a surface mount glass passivated standard rectifier designed for general-purpose applications. It features a maximum average forward rectified current of 1.0 A and a maximum repetitive peak reverse voltage of 1000 V. The device operates within a junction and storage temperature range of -55 to +150 °C. Key electrical characteristics include a typical instantaneous forward voltage of 1.0 V at 1 A, a maximum DC reverse current of 5 µA at 125°C, and a typical reverse recovery time of 1.8 µs. The component is housed in an eSGA (SOD-123FL) package.

Feature Summary

• Glass passivated construction ensures stable performance and reliability under various operating conditions.
• Very low profile design with a typical height of 1.0 mm, suitable for space-constrained surface mount applications.
• High temperature soldering capability guaranteed at 260°C for 10 seconds, facilitating robust assembly processes.

Applications

• General purpose rectification in lighting systems
• Power supplies for consumer electronics
• Portable devices and cellular phones

Procurement Notes

Verify the specific part number suffix against the manufacturer's official documentation to confirm exact packaging and tape-and-reel specifications. Ensure compliance with RoHS and halogen-free requirements as defined by IEC 61249-2-21. Confirm moisture sensitivity level 1 classification per J-STD-020 for storage and handling procedures. Cross-reference the AEC-Q101 qualification status if automotive-grade reliability is required for the intended application environment.

Selection Notes

Select the A7 variant based on the required maximum DC blocking voltage, which ranges from 50 V to 1000 V across the A1-A7 series. Consider the 1.0 A continuous current rating and the 45 A peak surge current capability for transient load conditions. Evaluate the thermal management requirements given the -55 to +150 °C operating range and the low forward voltage drop characteristics for efficiency optimization in power supply designs.

Part Context

The A7 belongs to the A1 through A7 series of surface mount glass passivated standard rectifiers manufactured by Good-Ark Semiconductor. This family shares common physical dimensions and electrical characteristics, differentiated primarily by their maximum repetitive peak reverse voltage ratings. The series is engineered for high-volume manufacturing in consumer electronics and portable device markets.

Replacement Considerations

Direct substitutes must match the SOD-123FL package, 1 A forward current, and 1000 V reverse voltage ratings. Verify that alternative components meet the same AEC-Q101 qualification and glass passivation standards to ensure equivalent reliability and performance in existing circuit designs.
