Overview
The Microsemi Corporation 1N5376A/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in an axial-lead T-18 package with tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 87V with a standard tolerance of ±10%. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 75 Ohms at a test current of 15 mA.
Feature Summary
- Provides stable voltage regulation across broad operating current and temperature ranges
- Withstands high surge stresses due to low thermal resistance design
- Flexible axial-lead mounting terminals for secure installation
- Moisture classification Level 1 requiring no dry pack storage
Applications
- Voltage regulation in power supply circuits
- Surge protection for sensitive electronic components
- Reference voltage generation in measurement systems
Procurement Notes
Verify that the ordering suffix TR12 corresponds to the specified tape and reel packaging format. Confirm the component meets RoHS compliance requirements if applicable, as leaded versions exist within this series. Ensure the procurement documentation matches the specific A suffix designation for the required ±10% voltage tolerance.
Selection Notes
Select this component when a 5-watt power dissipation rating is necessary for high-current applications. The T-18 axial package allows for flexible mounting on printed circuit boards or chassis. Consider the thermal resistance characteristics and derating curves to ensure adequate heat sinking for steady-state operation above 25°C ambient temperatures.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3V to 200V. The 'A' suffix identifies the specific ±10% tolerance variant, while the 'TR12' suffix indicates the tape and reel packaging option.
Replacement Considerations
Equivalent parts include the 1N5376AE3/TR12 and MX1N5376E3. Verify compatibility regarding terminal plating (tin-lead vs. matte tin) and moisture sensitivity levels before substitution.
