1N5368E3/TR13

Overview

The Microchip Technology 1N5368E3/TR13 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 volts with a standard tolerance of plus or minus 5 percent, indicated by the B suffix. The device features an axial-lead package and RoHS compliant tin plating. Electrical characteristics include a test current of 25 mA, a maximum dynamic impedance of 25 ohms, and a maximum reverse current of 0.5 microamperes. It operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards

Applications

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

Procurement Notes

Verify the component origin as the datasheet identifies Microsemi Scottsdale Division as the manufacturer. Confirm that the e3 suffix denotes RoHS compliance and the TR suffix indicates tape and reel packaging per EIA-296 standards. Ensure the specific part number matches the required 47-volt specification and 5-watt power rating before procurement.

Selection Notes

Select this component for applications requiring a 5-watt axial-leaded Zener diode with a 47-volt breakdown voltage. Consider the thermal resistance of 25°C/W junction-to-lead when designing heat sinking solutions. Verify that the plus or minus 5 percent tolerance meets the circuit requirements and that the operating temperature range suits the environmental conditions.
