Overview
The Microchip Technology 1N5353AE3/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 16 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates in an axial T-18 package and supports tape-and-reel packaging via the 'TR12' suffix. Electrical characteristics include a test current of 75 mA, a maximum reverse leakage current of 1.0 µA, and a maximum dynamic impedance of 2.5 Ω.
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 through-hole integration
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement systems
Procurement Notes
Verify component authenticity against official Microchip or Microsemi datasheets. Confirm that the specific ordering suffixes match the required voltage tolerance and packaging format. Ensure compliance with environmental standards such as RoHS where applicable. Validate thermal management requirements based on the intended mounting method and ambient conditions.
Selection Notes
Select this component when a 16 V regulation point with ±10% tolerance is required. The 5 W power dissipation rating necessitates adequate heat sinking to maintain performance within specified limits. Consider the T-18 package dimensions for PCB layout constraints. Verify that the operating temperature range meets the application's environmental demands.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now part of Microchip Technology). The series offers a wide selection of voltages from 3.3 V to 200 V. The 'e3' suffix indicates RoHS compliance, while 'TR12' specifies tape-and-reel packaging.
Replacement Considerations
Consult official manufacturer documentation for verified substitute part numbers. Cross-reference electrical parameters such as Zener voltage, tolerance, and power dissipation to ensure functional compatibility.
