Overview
The 10BQ040 is a surface-mount Schottky rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 1 A. The device utilizes the DO-214AA (SMB) package for compact PCB integration. Key electrical characteristics include a maximum DC reverse leakage current of 50 µA at 40 V and a typical forward voltage drop of 450 mV at 1 A. The component operates within a junction temperature range of -55°C to 150°C, ensuring stability in demanding thermal environments.
Feature Summary
- Schottky barrier technology provides low forward voltage drop for improved efficiency
- Surface-mount SMB package design enables small footprint on printed circuit boards
- Wide operating temperature range supports reliable performance in harsh conditions
Applications
- Power supply circuits requiring low loss rectification
- Battery charging systems
- Motor control applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm exact packaging and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements if mandated by your assembly standards. Cross-reference the DO-214AA package dimensions with your PCB footprint library to guarantee mechanical compatibility before finalizing procurement orders.
Selection Notes
Select this component when a low forward voltage drop is critical for system efficiency. The 40 V rating suits low-voltage DC bus applications. Verify that the 1 A current capacity aligns with the load requirements. Consider the SMB package size constraints relative to available board space. Confirm thermal management capabilities match the expected ambient operating temperatures.
Part Context
This part belongs to the 10BQ series of single Schottky rectifiers from SMC Diode Solutions. The series offers various voltage ratings while maintaining consistent current handling and package styles. These devices are engineered for general-purpose rectification in consumer electronics and industrial equipment where space savings and switching speed are prioritized over high-voltage blocking capabilities.
Replacement Considerations
The VS-10BQ040-M3/5BT from Vishay Semiconductors is a documented equivalent offering identical 40 V and 1 A specifications in the same SMB package. Verify pinout compatibility and slight variations in forward voltage characteristics between manufacturers before substitution.
