Overview
The Microchip Technology 1N5358CE3/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 22 V with a tight tolerance of ±2%. The device operates in an extended temperature range from -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum reverse leakage current of 0.5 µA, a dynamic impedance of 3.5 Ω, and a test current of 50 mA.
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 integration
- Constructed with a void-free transfer molded thermosetting epoxy body
Applications
- Voltage regulation circuits requiring high power dissipation
- Power supply protection against overvoltage conditions
- Reference voltage generation in industrial equipment
Procurement Notes
Verify the specific suffix configuration to ensure compliance with RoHS requirements and tape-and-reel packaging specifications. Confirm that the component meets the required thermal management standards for the intended application environment. Cross-reference datasheet parameters against design constraints to validate performance under maximum load conditions.
Selection Notes
Select this component when a 5-watt power rating and precise 22 V regulation are required. Ensure the circuit design accommodates the specified thermal resistance and maximum steady-state power dissipation limits. Verify compatibility with the T-18 package dimensions and axial lead spacing for PCB layout integration.
Part Context
This part belongs to the Microsemi Scottsdale Division 1N5333B through 1N5388B series of silicon Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options. The e3 suffix indicates RoHS compliance, while the TR12 suffix denotes tape-and-reel packaging.
Replacement Considerations
Compatible equivalents include the SMBG5358Ce3/TR13 surface mount variant and other 1N5358 variants with different tolerances such as 1N5358A or 1N5358B.
