1N5358B

Overview

The Microsemi Corporation 1N5358B is a silicon axial-leaded Zener diode with a nominal voltage of 22 V and a maximum power dissipation of 5.0 W at 25°C. It features a standard ±5% tolerance indicated by the B suffix, a test current of 50 mA, and a maximum dynamic impedance of 3.5 Ω. The device operates within a temperature range of -65°C to +150°C, has a maximum reverse leakage current of 0.5 µA at 16.7 V, and withstands a maximum surge current of 216 A.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for versatile installation
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against high surge stresses
• General-purpose electronic equipment utilizing wide selection of voltages

Procurement Notes

Verify that the component matches the specific JEDEC registered series designation and confirms the presence of the B suffix for the required ±5% tolerance. Ensure the procurement specification aligns with the plastic encapsulated T-18 package dimensions and lead configuration provided in the official datasheet to guarantee mechanical compatibility.

Selection Notes

Select this component when a 5-watt power rating and 22-volt regulation are required. Consider the low thermal resistance design for applications needing operation at high maximum DC currents with adequate heat sinking. Verify that the specified operating temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide voltage selection from 3.3 to 200 volts with various tolerance options identified by specific suffix letters on the part number.

Replacement Considerations

Surface mount equivalents such as SMBJ5358B or SMBG5358B are available. RoHS compliant versions can be obtained by adding the e3 suffix to the part number.
