1N5368/TR12

Overview

The Microchip Technology 1N5368/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 47 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 axial lead package. Electrical characteristics include a test current of 25 mA, a maximum dynamic impedance of 25 Ohms, and a maximum reverse current of 0.5 µA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole installation
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Applications

• Voltage regulation in power supply circuits
• Reference voltage generation in electronic systems
• Overvoltage protection applications

Procurement Notes

Verify the component status as this part number may be subject to discontinuance or manufacturing changes. Confirm RoHS compliance and specific screening levels if required for your application. Check official Microchip documentation for the most current product availability and ordering information before procurement.

Selection Notes

Select this component for applications requiring a 47 V reference with 5 W power dissipation capability. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits. Verify that the ±5% voltage tolerance meets the circuit requirements compared to tighter tolerance options available in the series.
