1N5384A/TR12

Overview

The Microsemi Corporation 1N5384A/TR12 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, housed in an axial-leaded T-18 plastic package with a TR suffix for tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 160 V with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 350 Ohms at a test current of 8.0 mA.

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 suitable for through-hole applications
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement equipment

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance and packaging details. Confirm RoHS compliance status as standard versions may not meet current environmental directives. Ensure adequate heat sinking is provided during operation to maintain performance within specified thermal limits.

Selection Notes

Select this component when a 160 V regulation point is required with a 5 W power dissipation capacity. Consider the T-18 package dimensions for board layout constraints. Evaluate thermal resistance requirements based on the intended mounting method and ambient temperature conditions.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5.0-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 to 200 volts with various tolerance options identified by suffix letters. These devices are designed for robust performance in demanding environments.

Replacement Considerations

Equivalent parts include other 5W Zener diodes with a 160V rating and similar axial leaded packages. Verify that replacement components match the electrical characteristics and physical dimensions for direct substitution.
