Overview
The onsemi BAWH56WT1G is a small signal switching diode in the AWH56 series, housed in an SC-70-3 surface-mount package. It features a dual configuration with a peak reverse voltage of 70 V and a maximum forward current of 150 mA. Key electrical characteristics include a fast recovery time of 6 ns, a maximum reverse current of 2.5 uA, and a typical forward voltage of 1.25 V. The device supports a maximum surge current of 2 A, has a power dissipation rating of 200 mW, and operates within a temperature range of -55 C to +175 C. It is qualified under AEC-Q101 standards.
Feature Summary
- Dual configuration for compact circuit integration
- Fast switching capability with 6 ns recovery time
- Automotive grade qualification (AEC-Q101)
- Extended operating temperature range up to 175 C
Applications
- High-speed signal switching circuits
- Automotive electronic systems requiring AEC-Q101 compliance
- Clamping and protection applications in consumer electronics
Procurement Notes
Verify the specific ordering suffix against official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets the required AEC-Q101 automotive qualification standards if intended for vehicle applications. Cross-reference the SC-70-3 package dimensions with your PCB footprint design to ensure mechanical compatibility during assembly.
Selection Notes
Select this component when a dual switching diode with fast recovery characteristics is required in a minimal footprint. The 70 V reverse voltage rating suits low-voltage signal processing tasks. Consider the 150 mA forward current limit for load requirements. The AEC-Q101 qualification makes it suitable for environments demanding higher reliability and thermal stability compared to standard commercial grades.
Part Context
This part belongs to the BAWH56 series of small signal switching diodes manufactured by onsemi. The series is designed for general-purpose high-speed switching applications. The WT1G suffix indicates the specific reel packaging and terminal finish. It falls under the broader category of silicon rectifiers and diodes used in discrete semiconductor solutions.
Replacement Considerations
Consult official substitution guides for equivalent dual switching diodes in SC-70 packages. Verify that any alternative part matches the 70 V reverse voltage, 6 ns recovery time, and AEC-Q101 automotive qualification requirements before implementation.
