1N5365/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5365/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 36 V with a ±10% tolerance (A suffix). The device operates within a temperature range of -65°C to +150°C and features a T-18 axial-lead package. Electrical characteristics include a test current of 30 mA, a maximum dynamic impedance of 11 Ohms, and a maximum reverse leakage current of 0.5 µA.

Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet revision status before procurement. Confirm that the specific ordering suffix matches required electrical tolerances and packaging formats. Ensure compliance with RoHS directives if lead-free variants are mandated. Check for discontinuance notifications or lifecycle changes associated with the manufacturer's product portfolio.

Single Zener Diodes Selection Notes

Select this component when a 36 V regulation point is required with moderate precision. The 5 W power rating supports high DC currents provided adequate heat sinking is implemented. Verify thermal resistance requirements against the application's ambient temperature and PCB copper pad specifications to ensure safe operation within the junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes. The series covers a voltage selection from 3.3 V to 200 V. Different suffix letters identify specific voltage tolerances, such as B for ±5%, A for ±10%, C for ±2%, and D for ±1%. The TR suffix indicates tape and reel packaging options available for automated assembly.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 5 W axial Zener diodes rated at 36 V. Verify mechanical dimensions of the T-18 package and thermal characteristics match the existing design constraints.
