Overview
The Microsemi 1N5347AE3/TR8 is a silicon Zener diode with a nominal voltage of 10V and a tolerance of ±10%. It features a 5W power dissipation rating, unidirectional polarity, and an axial lead T-18 package. The device is RoHS compliant (e3 suffix) and supplied in tape and reel format (TR8 suffix).
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range.
- Withstands high surge stresses and exhibits minimal voltage change versus current.
- Features flexible axial-lead mounting terminals for secure installation.
Applications
- Voltage regulation circuits requiring 10V reference.
- Power supply protection against overvoltage conditions.
- General purpose clamping applications in electronic systems.
Procurement Notes
Verify the specific suffixes to confirm compliance requirements and packaging. The e3 suffix indicates RoHS compliance, while TR8 denotes tape and reel packaging. Ensure the ordering part number matches the required tolerance and environmental specifications before procurement.
Selection Notes
Select this component when a 10V Zener voltage with ±10% tolerance is required. Consider the 5W power rating and thermal resistance characteristics for heat sinking needs. Verify that the axial lead form factor fits the mechanical constraints of the target assembly.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options defined by suffix letters.
Replacement Considerations
Equivalent parts within the 1N5333B-1N5388B series may be considered if they match the 10V specification and ±10% tolerance. Verify compatibility regarding package dimensions, thermal performance, and electrical ratings before substitution.
FAQ
What does the 'A' suffix indicate for this diode?
The 'A' suffix designates a standard voltage tolerance of plus or minus 10%.
Is this device suitable for surface mount applications?
No, this specific part uses an axial-lead T-18 package. Surface mount equivalents are available as SMBJ or SMBG series devices.
