1N5361AE3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5361AE3/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 27 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features an axial lead T-18 package. Electrical characteristics include a test current of 50 mA, a maximum dynamic impedance of 5.0 Ohms, and a maximum reverse leakage current of 0.5 µA. The component is RoHS compliant (e3 suffix) and supplied in tape and reel packaging (TR12).

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range.
• Features flexible axial-lead mounting terminals for through-hole applications.
• Withstands high surge stresses and exhibits minimal changes in voltage versus current.
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020.

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes against official documentation to confirm exact electrical tolerances and packaging configurations. Confirm that the 'A' suffix corresponds to the required ±10% voltage tolerance and the 'TR12' designation matches the intended reel specifications. Ensure compatibility with existing thermal management designs given the 5 W power dissipation rating.

Single Zener Diodes Selection Notes

Select this component when a 27 V regulation point with ±10% tolerance is required in a 5 W axial-leaded package. Consider the thermal resistance of 25 °C/W junction-to-lead for heat sinking requirements. Verify that the operating environment falls within the specified -65°C to +150°C range and that the moisture classification Level 1 meets storage constraints without dry pack requirements.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally developed by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 V to 200 V. The 'e3' suffix indicates RoHS compliance, while the 'TR' suffix denotes tape and reel packaging options available for automated assembly processes.
