Overview
The AL1K is a standard avalanche SMD rectifier diode from the AL1A...AL1M series by Diotec Semiconductor. It features a maximum average forward current (IFAV) of 1 A at 75°C and a peak forward surge current (IFSM) of 30 A at 60 Hz. The device has a reverse voltage rating of 800 V to 850 V, with a typical junction capacitance of 4 pF and a typical reverse recovery time of 1500 ns. Operating temperatures range from -50°C to +175°C for both junction and storage.
Feature Summary
- Standard avalanche capability for robust transient protection
- High thermal stability with extended operating temperature range up to 175°C
- Low leakage current characteristics for efficient power management
- Compact surface-mount design suitable for automated assembly
Applications
- General-purpose rectification in industrial electronics
- Power supply output stages
- Protection circuits requiring avalanche ruggedness

Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage grading and packaging configuration. Confirm compliance requirements such as RoHS and REACH status directly from the latest datasheet revision before finalizing procurement specifications.
Selection Notes
Select this component when a 1 A standard recovery rectifier with high reverse voltage blocking capability is required. Ensure the application environment supports the specified thermal resistance values and that the PCB layout provides adequate copper pad area for optimal heat dissipation during continuous operation.
Part Context
This part belongs to the AL1A through AL1M family of standard avalanche SMD rectifiers. The series offers various voltage ratings distinguished by color coding, with the AL1K specifically designated for the 800 V to 850 V range within the DO-214AC (SMA) package footprint.
Replacement Considerations
Consult official substitution lists for equivalent parts from other manufacturers. Verify pinout compatibility and electrical parameter margins before replacing.
