Overview
The Microchip Technology 1N5350C/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by Microsemi. It provides voltage regulation at a nominal Zener voltage of 13V with a tight tolerance of plus or minus 2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features flexible axial-lead mounting terminals in a T-18 package. It is supplied in tape and reel packaging.
Feature Summary
- Provides stable voltage regulation across broad operating current and temperature ranges
- Features flexible axial-lead mounting terminals for through-hole applications
- Withstands high surge stresses and exhibits minimal changes in voltage versus current
- Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020
Applications
- Voltage regulation circuits requiring 5W power dissipation
- High maximum DC current applications with adequate heat sinking
- Surge stress environments requiring robust semiconductor protection
Procurement Notes
Verify the specific suffix 'TR8' confirms tape and reel packaging as documented in the datasheet mechanical section. Confirm that the 'C' suffix strictly denotes the 2% voltage tolerance characteristic. Ensure the component source aligns with the Microsemi Scottsdale Division specifications provided in the official documentation.
Selection Notes
Select this component when a precise 13V reference with 2% tolerance is required. The 5W power rating necessitates consideration of thermal resistance and heat sinking strategies. Verify compatibility with the T-18 axial lead form factor and ensure the operating environment falls within the specified -65°C to +150°C range.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. Different suffix letters identify specific voltage tolerances, with the 'C' suffix designating the tighter 2% specification compared to standard B or A suffixes.
Replacement Considerations
Equivalent parts include other 13V 5W Zener diodes with 2% tolerance in the T-18 package. Cross-reference with the 1N5350B series for similar electrical characteristics, noting that the 'B' suffix indicates a 5% tolerance rather than 2%.
