1N5361A/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5361A/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 27V and ±10% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 0.5 µA at 19.4V and a dynamic impedance of 5.0 Ω. The device utilizes a T-18 axial lead package and includes a TR suffix for tape and reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating currents and temperatures
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses without sensitivity to electrostatic discharge

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific A suffix indicates ±10% tolerance rather than standard B suffix specifications. Confirm the TR suffix denotes tape and reel packaging format. Ensure compatibility with MIL-PRF-19500 screening requirements if military-grade reliability is necessary for the application.

Single Zener Diodes Selection Notes

Select this component when a 27V regulation point is required with moderate precision. Consider the 5W power dissipation capability and thermal resistance characteristics for heat sinking requirements. Evaluate the T-18 package dimensions against available board space constraints.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide voltage selection from 3.3V to 200V. The A suffix specifically designates a ±10% voltage tolerance, distinguishing it from tighter tolerance variants like C or D suffixes.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 27V 5W Zener diodes in T-18 packages. Verify electrical parameters such as dynamic impedance and reverse leakage current match original design requirements before substitution.
