1N5368BE3/TR12

Overview

The Microchip Technology 1N5368BE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 47 V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum dynamic impedance of 25 Ω at a test current of 25 mA. The device utilizes a T-18 axial lead package and supports tape-and-reel packaging.

Feature Summary

• Provides stable voltage regulation across broad operating currents and temperatures
• Withstands high surge stresses and maintains minimal voltage changes versus current
• Features flexible axial-lead mounting terminals for through-hole applications

Applications

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

Procurement Notes

Verify the component's JEDEC registration status and RoHS compliance before procurement. Confirm that the specific suffixes match the required tolerance and packaging format. Ensure the supplier provides valid traceability documentation for the manufacturer and lot codes.

Selection Notes

Select this component when a 47 V reference with moderate precision is required. Consider the thermal resistance characteristics and derating curves for high-current applications. Verify that the axial lead configuration fits the target PCB layout constraints.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5-watt Zener diodes manufactured by Microsemi (now Microchip). The series covers voltages from 3.3 V to 200 V with various tolerance options. The 'e3' suffix indicates RoHS compliance, while 'TR12' specifies the tape and reel packaging format.

Replacement Considerations

Compatible substitutes include other 1N5368 variants with matching voltage and power ratings. Surface mount equivalents such as SMBJ5368 are available for space-constrained designs. Verify electrical parameters and package dimensions before substitution.
