Overview
The Microchip Technology 1N5360AE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 25V and a ±10% tolerance. It utilizes an axial-lead T-18 package and operates within a temperature range of -65°C to +150°C. The device features a maximum reverse current of 0.5 µA at 19.4V, a dynamic impedance of 4.0 ohms at a test current of 50 mA, and a maximum surge current of 4.3 A.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and withstands ESD per MIL-STD-750 Method 1020
- Features flexible axial-lead mounting terminals for versatile integration
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement systems
Procurement Notes
Verify the specific suffix 'e3' confirms RoHS compliance and 'TR12' indicates tape and reel packaging. Confirm the manufacturer origin as Microsemi or Microchip Technology depending on the current corporate structure. Ensure the component matches the T-18 through-hole package dimensions before final procurement.
Selection Notes
Select this component when a 5-watt power dissipation rating is required for high-current applications. The ±10% tolerance suits general-purpose regulation where tight precision is not critical. Verify that the thermal resistance allows adequate heat sinking to maintain performance within the specified junction-to-lead limits.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide voltage selection from 3.3V to 200V. Different suffixes indicate varying voltage tolerances, such as B for ±5% and A for ±10%. The e3 suffix denotes lead-free, RoHS-compliant construction.
Replacement Considerations
Compatible substitutes include other 1N5360 variants with matching voltage and power ratings. Surface mount equivalents are available in SMBJ or SMBG packages. Cross-reference datasheets to ensure identical thermal characteristics and mechanical dimensions for direct replacement.
