Overview
The Microchip Technology 1N5358BE3/TR13 is a silicon 5-watt Zener diode with a nominal voltage of 22V. It features a ±5% tolerance and operates within a temperature range of -65°C to +150°C. The device utilizes a T-18 axial lead package and includes a TR suffix for tape and reel packaging. Electrical characteristics include a maximum dynamic impedance of 3.5 ohms, a maximum reverse current of 0.5 µA, and a maximum regulator current of 4.7 A.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals for secure installation
- Withstands high surge stresses during operation
- Minimal changes in voltage versus current as specified by voltage regulation
Applications
- Voltage regulation circuits requiring 5W power dissipation
- High current applications with adequate heat sinking
- General purpose Zener diode protection
Procurement Notes
Verify the component status before procurement, as this specific part number may be discontinued or subject to limited availability. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure the manufacturer designation matches the original Microsemi or current Microchip Technology specifications to maintain compliance with JEDEC registration standards.
Selection Notes
Select this component when a 22V Zener reference with 5W power handling is required. The B suffix indicates a standard 5% tolerance suitable for general applications. Consider the thermal resistance of 25°C/W junction-to-lead for proper heat sinking design. Verify that the T-18 package dimensions fit the target PCB layout constraints.
Part Context
This device belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The e3 suffix denotes RoHS compliance, while the TR suffix specifies tape and reel packaging for efficient surface mount or automated through-hole processing.
Replacement Considerations
Direct replacements within the same series include other 1N53xxB variants with different voltage ratings. Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B families. Verify pinout compatibility and thermal performance when substituting.
