Overview
The ABAV21W-HF is a small signal switching diode manufactured by Comchip Technology, designed for automotive applications. It features a peak reverse voltage of 250 V and a forward current rating of 200 mA. The device utilizes SOD-123 surface-mount packaging with a maximum power dissipation of 410 mW. Key electrical characteristics include a maximum diode capacitance of 5 pF. The component is RoHS compliant and marked with the code T3.
Feature Summary
- Automotive-grade reliability for vehicle electronics
- High-speed switching capability with low capacitance
- Compact SOD-123 surface-mount form factor
Applications
- Automotive circuit protection
- General purpose switching in vehicle systems
- Signal rectification in automotive modules
Procurement Notes
Verify the specific suffix and marking code against official Comchip Technology documentation to ensure correct part identification. Confirm RoHS compliance status through the manufacturer's latest product specifications. Cross-reference the datasheet revision history to validate electrical parameters before integration into design files.
Selection Notes
Select this component when automotive qualification is required for small signal switching tasks. The SOD-123 package offers space efficiency compared to larger alternatives. Ensure the 250 V reverse voltage rating exceeds the maximum circuit operating voltage. Verify that the 200 mA forward current capacity meets the load requirements of the target application.
Part Context
This part belongs to Comchip Technology's automotive diode series, distinct from standard commercial variants like the BAV21WS. The ABAV21W-HF designation indicates specific automotive reliability standards. It serves as a specialized replacement for general-purpose switching diodes in environments requiring higher durability and strict quality control.
Replacement Considerations
The BAV21WS is a comparable non-automotive alternative. Verify if the target application mandates automotive-specific certification before substituting with commercial grade parts.
