1N5361/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5361/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 27 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18-2 axial lead package. Electrical characteristics include a test current of 50 mA, a maximum dynamic impedance of 5.0 Ohms, and a maximum reverse leakage current of 0.5 µA. The component is supplied in tape and reel packaging.

Single Zener Diodes Procurement Notes

Verify the manufacturer origin as the datasheet identifies Microsemi Scottsdale Division. Confirm RoHS compliance via the e3 suffix if required. Ensure the TR12 suffix matches the specific tape and reel configuration needed for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component for applications requiring 5-watt power dissipation and a 27-volt regulation point. Consider the thermal resistance of 25°C/W junction-to-lead when designing heat sinking solutions. Verify that the ±5% tolerance meets the circuit requirements compared to tighter tolerance options available in the series.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V.
