Overview
The AL1M is a standard avalanche SMD rectifier diode from Diotec Semiconductor, rated for a maximum average forward current of 1 A at 75°C. It features a repetitive peak reverse voltage range of 1000 V to 1100 V and supports non-repetitive peak reverse avalanche energy up to 20 mJ. The device operates within a junction temperature range of -50°C to +175°C. Electrical characteristics include a typical forward voltage of less than 1.3 V at 1 A, leakage current under 3 µA at 25°C, and a typical reverse recovery time of 1500 ns.
Feature Summary
- Incorporates avalanche capability with a specified non-repetitive peak reverse avalanche energy rating of 20 mJ.
- Designed for surface-mount installation in the SMA (DO-214AC) package configuration.
- Supports high thermal performance with an extended operating junction temperature range up to +175°C.
Applications
- Standard commercial and industrial rectification circuits
- Power supply input stages requiring avalanche robustness
- General-purpose switching applications
Procurement Notes
Verify the specific part number against official Diotec documentation to confirm the 1000 V to 1100 V reverse voltage classification. Ensure that the required avalanche energy handling aligns with the 20 mJ specification provided in the datasheet. Confirm compliance with RoHS directives and check for any specific automotive qualifications if the application demands AEC-Q101 standards.
Selection Notes
Select this component when a standard recovery rectifier with integrated avalanche protection is required for surface-mount designs. The 1 A current rating and 1000 V+ blocking voltage make it suitable for general power conversion tasks. Consider the 1500 ns reverse recovery time for frequency limitations and ensure the PCB layout provides adequate copper area for thermal dissipation as specified.
Part Context
The AL1M belongs to the AL1A through AL1M series of standard avalanche SMD rectifiers manufactured by Diotec Semiconductor. This family shares common electrical parameters such as the 1 A average forward current and 175°C junction temperature limit, differentiated primarily by their repetitive peak reverse voltage ratings. The AL1M represents the highest voltage variant within this specific series lineup.
Replacement Considerations
Cross-reference with other manufacturers' SMA packages offering similar 1 A current and >1000 V reverse voltage ratings. Verify that replacement parts support comparable avalanche energy ratings if circuit protection relies on this feature. Ensure pinout compatibility and thermal resistance values match the original design constraints.
