1N5399G

Overview

The 1N5399G is a general-purpose silicon rectifier manufactured by Taiwan Semiconductor. It features a standard recovery configuration housed in a DO-15 (DO-204AC) axial leaded package. The device supports a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage of 1 kV. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 50 A, a typical reverse leakage current of 5 uA, and a maximum forward voltage drop of 1 V at rated current. The component operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Utilizes void-free molded plastic construction with UL 94 V-0 flammability classification
• Features diffused junction technology for high reliability and low reverse leakage
• Provides high forward surge capability suitable for demanding power applications

Applications

• General purpose rectification in AC/DC power supplies
• Freewheeling diode circuits in inductive loads
• Bridging and polarity protection in electronic systems

Procurement Notes

Verify the specific manufacturer datasheet for the exact electrical tolerances and thermal resistance values before finalizing the design. Confirm that the DO-15 package dimensions match the target PCB footprint requirements. Ensure compliance with RoHS directives if required by the end product specifications. Check for any specific ordering suffixes that may indicate halogen-free or tape-and-reel packaging options.

Selection Notes

Select this component when a robust 1.5 A rectifier with 1 kV blocking capability is required in an axial package. The standard recovery profile makes it suitable for lower frequency applications where fast switching is not critical. Consider the 150°C operating temperature limit for high-thermal environments. Compare against other manufacturers' equivalents if supply chain diversification is necessary.

Part Context

This part belongs to the 1N539xG series of general-purpose rectifiers from Taiwan Semiconductor. The 'G' suffix typically denotes a green compound, indicating halogen-free compliance according to IEC 61249-2-21 definitions. The series covers various reverse voltage ratings from 50 V to 1000 V, sharing the same 1.5 A current rating and DO-15 package form factor.

Replacement Considerations

Direct replacements include Vishay 1N5399GP and MCC 1N5399-TP. Verify pinout compatibility and ensure the substitute meets the 1.5 A current and 1 kV voltage requirements.
