10BQ100

Overview

The 10BQ100 is a surface-mount Schottky rectifier diode manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current of 1 A. The device utilizes the DO-214AA (SMB) package, designed for efficient space-constrained PCB layouts. Key electrical characteristics include a low forward voltage drop of approximately 790 mV at 1 A and a maximum reverse leakage current of 5 µA at 100 V. The component supports a junction temperature range from -55°C to +175°C, ensuring reliable operation in demanding thermal environments.

Feature Summary

• Low forward voltage drop for improved power efficiency
• High-frequency operation capability
• Guard ring structure for enhanced ruggedness and long-term stability

Applications

• Power supply circuits
• Power management systems
• General-purpose power conversion applications

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape-and-reel or cut tape, as these affect handling but not electrical function. Confirm RoHS compliance status if required by assembly specifications. Ensure the DO-214AA footprint matches the design layout. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage, low-current rectification. The DO-214AA package offers a smaller footprint compared to axial leads. Consider the 100 V rating margin relative to circuit peak inverse voltages. Evaluate thermal management needs based on the 1 A continuous current rating and ambient operating conditions.

Part Context

This part belongs to the 10BQ series of Schottky rectifiers from SMC Diode Solutions. The series includes variants with different current ratings, such as the 30BQ100 which handles higher currents. These devices are engineered for general-purpose switching and rectification tasks where low loss and fast response are prioritized over high-voltage blocking capabilities.

Replacement Considerations

Direct pin-to-pin replacements within the same package family should be verified against the specific current rating requirements. Other manufacturers offering DO-214AA Schottky diodes with 100 V and 1 A ratings may serve as alternatives if electrical parameters align.
