Overview
The AS3BJHM3/5BT is a standard avalanche surface-mount rectifier manufactured by Vishay General Semiconductor. It features a glass passivated chip junction and is housed in an SMB (DO-214AA) package. The device supports a maximum repetitive peak reverse voltage of 600 V and a maximum DC forward current of 3.0 A. It exhibits a typical instantaneous forward voltage of 0.98 V at 3.0 A and 25 °C, with a maximum reverse current of 20 µA at 600 V. The component operates within a temperature range of -55 to +175 °C and is qualified under the AEC-Q101 automotive standard.
Feature Summary
- Glass passivated chip junction for enhanced reliability
- Controlled avalanche characteristics for robust performance
- Low leakage current and high forward surge capability
- Automotive grade qualification compliant with AEC-Q101
Applications
- General purpose rectification in power supplies
- Freewheeling diodes for consumer electronics
- Inverter and converter circuits
- Telecommunication equipment applications
Procurement Notes
Verify that the ordering code matches the specific suffix requirements for your application. Confirm the package type and lead configuration align with your PCB design. Ensure compliance with RoHS directives and material categorization standards before finalizing procurement decisions.
Selection Notes
Select this component when a 600 V rating and 3 A continuous current are required in a compact SMB package. Consider its thermal resistance values for heat dissipation planning. Verify that the avalanche energy rating meets the transient protection needs of the target circuit environment.
Part Context
This part belongs to the AS3BD, AS3BG, and AS3BJ series of standard avalanche surface-mount rectifiers. These devices share common mechanical data and feature sets, differentiated primarily by their voltage ratings. The series is designed for automated placement and offers low profile dimensions suitable for space-constrained designs.
Replacement Considerations
Direct substitutes include other Vishay parts from the same AS3BJ series with identical electrical characteristics. Cross-referencing with generic SMB package rectifiers requires verifying voltage, current, and thermal parameters match the original specifications.
