Overview
The Microsemi Corporation 1N5386A/TR12 is a silicon Zener diode with a nominal voltage of 180V and a power dissipation rating of 5.0 watts at 25°C. It features an A suffix indicating a ±10% tolerance and utilizes a T-18 axial lead package. The device operates within a temperature range of -65°C to +150°C, has a maximum reverse current of 0.5 µA, and includes a TR suffix denoting tape and reel packaging.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and exhibits minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for versatile integration
Applications
- Voltage regulation in electronic circuits
- Protection against transient voltage spikes
- Reference voltage generation in power supplies
Procurement Notes
Verify the specific suffixes on the component marking to confirm the exact voltage tolerance (A for ±10%) and packaging format (TR for tape and reel). Ensure that the procurement documentation explicitly references the JEDEC registered series data to validate electrical characteristics against the official datasheet specifications.
Selection Notes
Select this component when a 5-watt power rating and a 180V breakdown voltage are required. Consider the ±10% tolerance if tighter precision is not critical. Verify thermal management requirements, as the device requires adequate heat sinking to maintain performance at maximum DC currents.
Part Context
This part belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3V to 200V, utilizing plastic encapsulated axial leads designed for robust operation in various industrial applications.
Replacement Considerations
Equivalent parts include other 5W Zener diodes with a 180V rating and ±10% tolerance in a T-18 package. Verify pinout compatibility and thermal resistance specifications before substitution.
