1N5359/TR12

Overview

The Microchip Technology 1N5359/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, manufactured by Microsemi. It provides voltage regulation at a nominal Zener voltage of 24 V with a standard ±5% tolerance indicated by the 'B' 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 maximum dynamic impedance of 3.5 Ohms and a maximum reverse current of 0.5 µA. The component is available in tape and reel packaging as specified by the 'TR' suffix.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for Through Hole installation
• 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

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify the specific suffix configuration against the datasheet to confirm tolerance and packaging options. Confirm RoHS compliance status if required, as it depends on the presence of the e3 suffix. Ensure the procurement channel supports the TR (Tape and Reel) format. Check for any military screening prefixes if higher reliability levels are needed for the application environment.

Selection Notes

Select this component when a 5-watt power dissipation rating is required for high-current applications. The 24 V nominal voltage and ±5% tolerance suit general-purpose regulation tasks. Consider the thermal resistance and derating curves for proper heat sinking design. Verify that the axial lead form factor fits the mechanical constraints of the target PCB layout.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally produced by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5359 variant specifically targets the 24 V regulation segment within this high-power axial-leaded family.
