Overview
The Microsemi Corporation 1N5374E3/TR13 is a silicon Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 75 V with a standard tolerance of ±10%. The device features a 5.0-watt power dissipation rating and operates within a temperature range of -65°C to +150°C. Packaged in an axial T-18 case, it utilizes RoHS compliant annealed matte-tin plating for solderability.
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 suitable for various board configurations
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack
Applications
- Voltage regulation circuits requiring 5-watt power handling
- Surge protection applications utilizing high peak current capabilities
- General purpose electronic equipment operating in wide temperature environments
Procurement Notes
Verify that the ordering suffix matches the required specifications. Confirm the presence of the e3 suffix indicates RoHS compliance and the TR suffix denotes tape and reel packaging. Ensure the component meets the specific voltage tolerance requirements associated with the A suffix designation before procurement.
Selection Notes
Select this component when a 75 V Zener reference is needed with a 5-watt power rating. Consider the thermal resistance characteristics and derating curves if operating near maximum limits. Verify compatibility with existing PCB layouts due to the T-18 axial lead package dimensions and weight specifications.
Part Context
This part belongs to the Microsemi 1N5333-5388B series of silicon 5-watt Zener diodes. The series covers a voltage selection from 3.3 to 200 volts. The e3 suffix designates RoHS compliant devices, while the TR suffix indicates tape and reel packaging options available for automated assembly processes.
Replacement Considerations
Surface mount equivalents are available as SMBJ5374 or SMBG5374. Other manufacturers offer cross-reference parts such as 1N5374 from Motorola or NJ Semi. Verify pinout and mechanical dimensions match the T-18 package before substitution.
