1N5358AE3/TR12

Overview

The Microchip Technology 1N5358AE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation across broad operating current and temperature ranges. It features a nominal Zener voltage of 22 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and utilizes an axial T-18 package. Electrical characteristics include a maximum reverse leakage current of 0.5 µA at 15.8 V and a maximum dynamic impedance of 3.5 Ω.

Feature Summary

• Provides stable voltage regulation over a wide 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
• RoHS compliant construction available via the e3 suffix designation

Applications

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

Procurement Notes

Verify component authenticity and datasheet revision status prior to integration. Confirm that the specific ordering suffixes match the required tolerance and packaging specifications. Ensure thermal management strategies align with the specified junction-to-lead thermal resistance values for reliable operation under maximum load conditions.

Selection Notes

Select this component when a 22 V reference with moderate precision is required in high-power environments. The 5 W dissipation rating supports robust performance with adequate heat sinking. Consider the ±10% tolerance for general-purpose regulation where tighter specifications are unnecessary. Evaluate thermal derating curves for ambient temperature constraints.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3 V to 200 V in a standardized 5 W axial package. The 'e3' suffix indicates RoHS compliance, while 'TR12' specifies tape and reel packaging options for automated assembly processes.

Replacement Considerations

Consult manufacturer documentation for direct equivalents within the same series or cross-reference with other manufacturers offering compatible 5 W axial Zener diodes with matching voltage and tolerance ratings.
