1N5350B

Overview

The Microsemi Corporation 1N5350B is a silicon axial-leaded Zener diode with a nominal voltage of 13V and a ±5% tolerance. It features a maximum power dissipation of 5.0 watts at 25°C, operating within a temperature range of -65°C to +150°C. The device has a maximum dynamic impedance of 2.5 ohms and a maximum reverse current of 1.0 µA tested at 9.9V. It utilizes a T-18 plastic encapsulated package.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and operates reliably under high maximum DC currents when adequately heat sunk
• Features flexible axial-lead mounting terminals for versatile circuit integration

Applications

• Voltage regulation in electronic circuits
• Overvoltage protection for sensitive components
• Reference voltage generation in power supplies

Procurement Notes

Verify the specific manufacturer lot and RoHS compliance status upon procurement, as suffixes like e3 indicate lead-free variants. Confirm that the component matches the JEDEC registered specifications for the 1N5333-5388B series. Ensure proper handling procedures are followed during installation to maintain the integrity of the plastic encapsulation and terminal plating.

Selection Notes

Select this component for applications requiring a precise 13V reference with a tight ±5% tolerance. Consider the 5-watt power rating and thermal resistance characteristics when designing the heat sinking requirements. Verify that the axial lead configuration fits the available PCB space and mounting constraints compared to surface mount alternatives.

Part Context

This part belongs to the JEDEC registered 1N5333 through 1N5388B series of 5.0 watt silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V, utilizing a standard T-18 plastic encapsulated package with axial leads for reliable performance in various industrial and commercial environments.

Replacement Considerations

Surface mount equivalents such as SMBJ5350B or SMBG5350B are available from the same series. Military screening options including JAN, JANTX, and JANTXV can be obtained by adding MQ, MX, or MV prefixes respectively.
