1N5383A/TR8

Overview

The Microsemi Corporation 1N5383A/TR8 is a silicon Zener diode with a nominal voltage of 150V and a tolerance of ±10%. It features a maximum power dissipation of 5.0 watts at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes a T-18 axial lead package and includes a TR suffix for tape and reel packaging. Electrical characteristics include a test current of 8.0 mA, a maximum dynamic impedance of 330 ohms, and a maximum reverse current of 0.5 µA.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Features flexible axial-lead mounting terminals for through-hole integration
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

• Voltage regulation in electronic circuits
• Surge protection applications
• Reference voltage generation

Procurement Notes

Verify the specific suffix 'A' confirms the required ±10% voltage tolerance. Confirm the 'TR' suffix indicates tape and reel packaging rather than cut tape or bulk. Ensure the component meets RoHS compliance requirements if applicable, as standard versions may differ from e3 variants. Validate that the manufacturer designation aligns with current Microchip Technology holdings.

Selection Notes

Select this component when a 150V Zener voltage with ±10% tolerance is required. Consider the 5-watt power rating and thermal resistance of 25°C/W junction-to-lead for heat sinking needs. Verify the T-18 axial lead package fits the board layout constraints. Check if tighter tolerances like ±5% (B suffix) are needed for stricter regulation requirements.

Part Context

This part belongs to the JEDEC registered 1N5333 through 1N5388 series of 5.0 watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. Different suffix letters identify specific voltage tolerances, such as A for ±10% and B for ±5%. The plastic encapsulated devices have a Level 1 moisture classification.

Replacement Considerations

Equivalent parts within the same series include 1N5383B for ±5% tolerance or 1N5383C for ±2% tolerance. Surface mount equivalents are available as SMBJ5383B or SMBG5383B. RoHS compliant versions can be identified by adding the e3 suffix to the part number.
