1N5383CE3/TR12

Overview

The Microsemi Corporation 1N5383CE3/TR12 is a single silicon Zener diode with a nominal voltage of 150 V and a power dissipation rating of 5.0 W at 25 °C. It features a tight ±2% voltage tolerance, indicated by the 'C' suffix, and utilizes an axial-lead T-18 package. The device operates within a temperature range of -65 °C to +150 °C and includes RoHS compliance via the 'e3' suffix.

Feature Summary

• Provides precise voltage regulation over 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
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Applications

• Voltage regulation circuits requiring stable reference voltages
• Power supply protection against transient voltage spikes
• Overvoltage clamping in electronic systems

Procurement Notes

Verify that the component matches the specific JEDEC registered series designation and confirms the presence of the 'e3' suffix for lead-free compliance. Ensure the 'TR' suffix indicates tape and reel packaging as required for automated assembly processes. Cross-reference the manufacturer's latest discontinuance notifications to confirm active production status before finalizing procurement plans.

Selection Notes

Select this component when a 150 V Zener diode with a strict ±2% tolerance is required for precision applications. The 5.0 W power rating supports high maximum DC currents when adequate heat sinking is provided. Consider the thermal resistance characteristics and the specific T-18 package dimensions to ensure compatibility with the intended circuit board layout and mechanical constraints.

Part Context

This part belongs to the 1N5333B through 1N5388B series of JEDEC registered axial-leaded 5.0 watt Zener diodes manufactured by Microsemi. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by specific suffix letters. These plastic encapsulated devices are designed for robust performance in demanding environments.

Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available. Military equivalent screening levels can be obtained by adding MQ, MX, or MV prefixes to the base part numbers.
