Overview
The Microchip Technology 1N5358CE3/TR8 is a silicon Zener diode with a nominal voltage of 22V and a power dissipation rating of 5.0W at 25°C. It features a tight voltage tolerance of ±2% (C suffix) and operates within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package, offers RoHS compliance via the e3 suffix, and supports tape-and-reel packaging indicated by the TR suffix.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals for through-hole applications
- Withstands high surge stresses and exhibits minimal voltage change versus current
- Moisture classification Level 1 requiring no dry pack storage
Applications
- Voltage regulation in electronic circuits
- Surge protection applications
- Reference voltage generation
Procurement Notes
Verify that the component matches the specific JEDEC registered series requirements. Confirm the presence of the C suffix for the required ±2% tolerance and the e3 suffix for lead-free compliance. Ensure the TR suffix aligns with the necessary tape-and-reel packaging specifications for automated assembly processes.
Selection Notes
Select this component when a precise 22V reference is needed with strict tolerance limits. The 5W power rating allows operation at high DC currents provided adequate heat sinking is implemented. Consider the thermal resistance characteristics and derating curves if ambient temperatures exceed standard conditions or if mounted on FR4 PCBs.
Part Context
This part belongs to the 1N5333B through 1N5388B series of 5-watt Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series covers a wide voltage selection from 3.3V to 200V. The 1N5358 variant specifically targets the 22V regulation point within this extensive lineup.
Replacement Considerations
Equivalent parts include the 1N5358B for standard tolerance or the SMBG5358Ce3 for surface mount equivalents. Verify mechanical dimensions and electrical parameters against the original design requirements before substitution.
