1N5351/TR8

Overview

The Microchip Technology 1N5351/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 14V with a ±2% tolerance, indicated by the 'C' 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 100 mA, a maximum dynamic impedance of 2.5 Ohms, and a maximum reverse current of 1.0 µA.

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 Level 1 requiring no dry pack

Applications

• Voltage regulation in power supply circuits
• Reference voltage sources for electronic systems
• Overvoltage protection components

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tolerance and packaging details. Confirm RoHS compliance status as it varies by suffix. Check for product discontinuance notifications or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a precise 14V regulation point is required with tight ±2% tolerance. Ensure adequate heat sinking is provided to maintain the rated 5W power dissipation capability. Verify that the axial lead form factor fits the target PCB layout constraints.

Part Context

This part belongs to the Microsemi (now Microchip) 1N5333-5388B series of 5-watt silicon Zener diodes. The series covers a wide voltage selection from 3.3V to 200V. The TR8 suffix indicates the device is supplied in tape and reel packaging, suitable for automated assembly processes.

Replacement Considerations

Consult official datasheets for cross-reference data. Equivalent parts may be found within the same 1N53xx series family or from other manufacturers offering compatible 5W axial Zener diodes with matching voltage and tolerance specifications.
