Overview
The Diotec Semiconductor AL1J is a standard avalanche SMD rectifier diode belonging to the AL1A through AL1M series. It features a maximum average forward current (IFAV) of 1 A at 75°C and a peak repetitive reverse voltage (VRRM) ranging from 600 V to 650 V. The device supports a non-repetitive peak forward surge current of 27 A at 50 Hz or 30 A at 60 Hz. Electrical characteristics include a typical junction capacitance of 4 pF, a typical reverse recovery time of 1500 ns, and a maximum leakage current of 3 µA at 25°C. Thermal resistance values are specified as 75 K/W junction-to-ambient and 40 K/W junction-to-terminal.
Feature Summary
- Incorporates avalanche rating capability for handling specific energy conditions
- Designed with a surface-mount package suitable for automated assembly processes
- Provides high thermal stability across an extended operating temperature range
Applications
- General-purpose rectification in commercial and industrial electronic circuits
- Power supply input stages requiring standard recovery characteristics
- Protection circuits utilizing avalanche energy absorption capabilities
Procurement Notes
Verify the exact part number against official Diotec Semiconductor documentation to confirm specifications. Ensure compliance with RoHS and ELV directives as stated in the datasheet. Confirm mounting requirements involve appropriate copper pad dimensions on the printed circuit board for optimal thermal performance. Check for any specific automotive qualifications if required by the application environment.
Selection Notes
Select this component when a 1 A average forward current and approximately 600 V reverse voltage rating are required. Consider the 1500 ns reverse recovery time for frequency limitations. Evaluate the thermal resistance parameters against the expected ambient temperature and heat dissipation needs. Verify that the avalanche energy rating meets the transient requirements of the target circuit design.
Part Context
The AL1J is part of the broader AL1A...AL1M family of standard avalanche SMD rectifier diodes manufactured by Diotec Semiconductor. This series offers various voltage ratings from 100 V to 1000 V, distinguished by color coding. The AL1J specifically addresses applications needing higher voltage blocking capabilities within the same physical footprint and electrical current framework as lower-voltage variants in the lineup.
Replacement Considerations
Consult official manufacturer substitution lists for verified equivalents. Cross-reference key parameters such as IFAV, VRRM, and package type when evaluating alternative components.
