1N5368AE3/TR12

Overview

The Microchip Technology 1N5368AE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 47 V and ±10% tolerance. It operates in the -65°C to +150°C range, featuring a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 25 Ohms at a test current of 25 mA, a maximum reverse leakage current of 0.5 µA, and a maximum surge current of 210 A.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole integration

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High surge stress protection applications
• Equipment operating within extreme temperature environments

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number against official datasheets. Confirm RoHS compliance status via the e3 suffix and ensure the TR12 tape and reel packaging matches specific production requirements. Validate that the device meets JEDEC registration standards before final procurement decisions.

Selection Notes

Select this component when a 47 V reference is required with ±10% tolerance. The 5-watt rating supports high DC currents with adequate heat sinking. Ensure the circuit design accommodates the specified thermal resistance and maximum surge current limits for reliable long-term operation under varying load conditions.

Part Context

This device belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon Zener diodes. Manufactured by Microsemi (now Microchip Technology), these components utilize void-free transfer molded epoxy bodies. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options defined by suffix letters.

Replacement Considerations

Consult the official datasheet for equivalent parts within the same series or other manufacturers offering compatible 5W axial Zener diodes. Verify that any substitute matches the 47V nominal voltage, ±10% tolerance, and T-18 package dimensions.
