1N5354C/TR12

Overview

The Microchip Technology 1N5354C/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation with a nominal Zener voltage of 17 V and a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates in a T-18 axial leaded package, suitable for through-hole mounting. Electrical characteristics include a maximum reverse current of 0.5 µA at 12.2 V and a dynamic impedance of 2.5 Ω. It withstands high surge stresses and features minimal voltage change versus current.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole integration
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Moisture classification Level 1 requiring no dry pack

Applications

• Voltage regulation circuits requiring precise tolerance
• Power supply reference applications
• Protection against overvoltage conditions

Procurement Notes

Verify component authenticity and datasheet alignment before procurement. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Ensure compliance with RoHS standards if applicable to the manufacturing process. Check for any discontinuance notifications or lifecycle status updates from the manufacturer prior to finalizing orders.

Selection Notes

Select this component when a 17 V reference with ±2% precision is required in a 5 W power dissipation package. Consider the thermal resistance and derating curves for adequate heat sinking. Verify that the axial lead form factor fits the PCB layout constraints. Compare dynamic impedance specifications against circuit sensitivity requirements.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip). The series offers a wide selection of voltages from 3.3 V to 200 V. The 'TR12' suffix indicates tape and reel packaging, while the 'C' suffix denotes the tighter ±2% voltage tolerance compared to standard B or A suffixes.

Replacement Considerations

Equivalent parts within the 1N5333-5388B series may be considered if voltage and tolerance match. Verify mechanical dimensions and lead spacing compatibility. Ensure thermal performance characteristics align with the original design requirements.
