Overview
The Microchip Technology 1N5352C/TR12 is a silicon Zener diode with a nominal voltage of 15V and a power dissipation rating of 5W. It features a tight tolerance of ±2% (indicated by the 'C' suffix) and operates within a temperature range of -65°C to +150°C. The device utilizes a T-18 axial lead package and includes a tape and reel option (TR suffix). Electrical characteristics include a maximum dynamic impedance of 2.5 Ohms, a reverse current of 1.0 µA at 10.8V, and a maximum regulator current of 6.3A.
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 changes in voltage versus current
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B with no dry pack required
Applications
- Voltage regulation circuits requiring precise tolerance
- Power supply protection against overvoltage conditions
- Reference voltage generation in electronic systems
Procurement Notes
Verify the specific suffix requirements for your application. The 'C' suffix indicates a ±2% voltage tolerance, while the 'TR' suffix denotes tape and reel packaging. Confirm that the component meets all necessary environmental and screening standards before procurement.
Selection Notes
Select this component when a 15V Zener voltage with tight ±2% tolerance is required. Ensure the design accommodates the 5W power dissipation and provides adequate heat sinking. Verify compatibility with the T-18 axial lead package and tape and reel handling if automated assembly is used.
Part Context
This part belongs to the JEDEC registered 1N5333-5388B series of 5.0 watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The 'C' suffix specifically identifies devices with tighter ±2% tolerances compared to standard B or A suffix variants.
Replacement Considerations
Equivalent parts within the 1N5333-5388B series can be considered if voltage and tolerance match. Verify thermal resistance and package dimensions for direct replacement. Military screening prefixes (MQ, MX, MV) are available for enhanced reliability requirements.
