Overview
The Microsemi Corporation 1N5383/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation between 3.3 and 200 volts. It features a T-18 axial-lead plastic package with a nominal Zener voltage of 150 V and a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and includes a TR suffix indicating tape and reel packaging per EIA-296 standards.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals suitable 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 requiring no dry pack
Applications
- Voltage regulation circuits requiring 5-watt power dissipation
- High maximum DC current operations with adequate heat sinking
- Surge stress protection in electronic systems
Procurement Notes
Verify the specific suffix configuration against official datasheets to confirm tolerance levels and packaging options. Confirm RoHS compliance status as standard versions may differ from e3 variants. Ensure thermal management aligns with the specified junction-to-lead resistance values during integration.
Selection Notes
Select this component when a 150-volt regulation point is required with a 10-percent tolerance. Consider the T-18 package dimensions for board layout constraints. Evaluate thermal derating curves if ambient temperatures exceed standard operating limits or if steady-state power dissipation approaches maximum ratings.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by suffix letters such as A, B, C, and D.
Replacement Considerations
Equivalent parts include other 5-watt Zener diodes with a 150V rating and similar axial lead packages. Verify that substitute components meet the same thermal resistance and surge current specifications to ensure circuit reliability.
