Overview
The AS1M-HF is a general-purpose rectifier diode manufactured by Comchip Technology. It features a 1000V reverse voltage rating and supports an average rectified current of 1A. The component utilizes the SMA (DO-214AC) surface-mount package, designed for efficient PCB integration. This single-diode configuration is engineered for reliable performance in standard rectification applications requiring high reverse voltage blocking capabilities.
Feature Summary
- High reverse voltage blocking capability rated at 1000V
- Surface-mount construction in the SMA/DO-214AC package
- Designed for general-purpose rectification tasks
Applications
- General-purpose power supply rectification
- DC-DC converter input/output stages
- Reverse polarity protection circuits
Procurement Notes
Verify the specific datasheet version to confirm thermal resistance values and maximum junction temperature limits before finalizing the design. Ensure the SMA footprint matches the target PCB layout. Confirm RoHS compliance status if required by the end-product specifications. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.
Selection Notes
Select this component when a 1000V rating is necessary for the circuit's peak inverse voltage requirements. The SMA package is suitable for automated surface-mount assembly processes. Consider the forward voltage drop characteristics relative to the load current to ensure efficiency meets system targets. Verify that the 1A continuous current rating exceeds the application's maximum steady-state demand.
Part Context
This device belongs to Comchip Technology's line of surface-mount rectifiers. It shares the SMA physical footprint with other variants in the series but differs in voltage and recovery speed ratings. The 'HF' suffix typically indicates Halogen-free manufacturing compliance. It serves as a standard solution for medium-voltage rectification needs in compact electronic designs.
Replacement Considerations
Check for direct substitutes such as the US1M-HF or ES1M-HF from the same manufacturer, noting differences in recovery time. Other manufacturers offer equivalent SMA packages with matching 1000V/1A ratings, but verify pinout compatibility and thermal characteristics carefully.
