1N5362A/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5362A/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by Microsemi. It provides voltage regulation at a nominal Zener voltage of 28V with a ±10% tolerance, indicated by the 'A' suffix. The device operates in a T-18 axial-lead package and is supplied in tape and reel format per EIA-296 standards. Electrical characteristics include a maximum reverse current of 0.5 µA and a dynamic impedance of 6.0 Ω at a test current of 50 mA. It withstands operating temperatures from -65°C to +150°C.

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 voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5W power dissipation
• Power supply reference designs
• Protection against overvoltage conditions

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the 1N5362A part number originates from the Microsemi product line now integrated into Microchip Technology. Confirm that the TR12 suffix correctly denotes the tape and reel packaging configuration. Ensure the component meets the required RoHS compliance status if applicable to your assembly process, noting that standard versions may differ from e3 compliant variants.

Single Zener Diodes Selection Notes

Select this component when a 28V Zener voltage with ±10% tolerance is required for high-power applications up to 5 watts. The axial lead design facilitates easy integration into through-hole PCB layouts. Consider the thermal resistance specifications and ensure adequate heat sinking is provided to maintain operation within the specified junction temperature limits during steady-state power dissipation.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally developed by Microsemi. The series offers a wide selection of voltages ranging from 3.3V to 200V. The 'A' suffix specifically identifies the ±10% voltage tolerance variant, distinguishing it from B (±5%), C (±2%), and D (±1%) tolerance options within the same physical package family.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5362A equivalents. Verify that any substitute matches the 28V Zener voltage, 5W power rating, and T-18 axial package dimensions. Ensure the replacement maintains similar dynamic impedance and leakage current characteristics for circuit compatibility.
