1N5393-AQ

Overview

The 1N5393-AQ is a standard recovery rectifier diode manufactured by Diotec Semiconductor. It features a single diode configuration housed in a DO-204AC (DO-15) through-hole package. Key electrical parameters include a maximum repetitive reverse voltage of 200 V and an average forward current rating of 1.5 A. The device supports a maximum non-repetitive peak forward surge current of 50 A. It operates within a junction temperature range from -55 °C to +175 °C, ensuring reliability in demanding thermal environments.

Feature Summary

• Glass-passivated junction structure for high reliability
• Low leakage current characteristics
• High thermal stability with extended operating temperature range

Applications

• General purpose rectification
• Polarity protection circuits
• Free-wheeling diode applications

Procurement Notes

Verify the specific suffix 'AQ' against the official Diotec Semiconductor datasheet to confirm automotive qualification status or specific material compliance requirements. Ensure the DO-15 package dimensions match the target PCB footprint. Cross-reference the manufacturer's latest documentation for any updates on RoHS or REACH compliance declarations prior to final procurement decisions.

Selection Notes

Select this component for applications requiring robust standard recovery performance with high thermal endurance. The 200 V reverse voltage rating suits low-to-medium voltage AC/DC conversion tasks. Consider the 1.5 A continuous current capability and 50 A surge tolerance when designing power stages subject to transient loads. Verify that the through-hole mounting style aligns with the assembly process constraints.

Part Context

This part belongs to the 1N4/1N5 series of standard recovery rectifiers. It shares the same physical package and core electrical ratings as the commercial 1N5393 variant, distinguished primarily by the 'AQ' suffix which typically denotes enhanced quality or automotive-grade screening protocols defined by the manufacturer.

Replacement Considerations

Direct functional substitutes include the commercial grade 1N5393 from Diotec Semiconductor or equivalent parts from other manufacturers such as Vishay (e.g., 1N5393GP/56-E3). Ensure replacement parts maintain the DO-15 package and identical 200 V / 1.5 A ratings. Automotive replacements must verify specific 'AQ' or equivalent automotive certification if required by the design.
