1N5354CE3/TR12

Overview

The Microchip Technology 1N5354CE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B-1N5388B series, manufactured by Microsemi. It provides voltage regulation at 17 V with a tight ±2% tolerance. The device operates within a temperature range of -65°C to +150°C and features an axial T-18-2 package. Electrical characteristics include a maximum reverse current of 0.5 µA, a dynamic impedance of 2.5 Ω, and a test current of 70 mA.

Feature Summary

• Provides stable voltage regulation across broad operating currents and temperatures
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features minimal changes in voltage versus current as specified by voltage regulation

Applications

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

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and check for specific military screening prefixes if required. Ensure proper handling procedures are followed due to the through-hole packaging format. Validate that the ordering suffix matches the intended reel configuration.

Selection Notes

Select this component when precise voltage regulation is required at 17 V with a narrow tolerance band. The 5-watt power dissipation rating supports high-current applications provided adequate heat sinking is implemented. Consider the wide operating temperature range for harsh environments. Verify thermal resistance requirements against the specific PCB layout and ambient conditions.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5-watt Zener diodes. The 'C' suffix indicates a ±2% voltage tolerance, while 'e3' denotes lead-free construction. The 'TR12' suffix specifies tape and reel packaging. These devices utilize void-free transfer molded thermosetting epoxy bodies meeting UL94V-0 standards.

Replacement Considerations

Equivalent parts within the same series include 1N5354B (±5% tolerance) or 1N5354D (±1% tolerance). Cross-reference with other manufacturers offering 5W axial Zener diodes rated at 17V, ensuring matching power dissipation and package dimensions.
