1N5383AE3/TR12

Overview

The Microsemi Corporation 1N5383AE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation applications. It features a nominal Zener voltage of 150 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial leaded package. Electrical characteristics include a maximum dynamic impedance of 330 Ohms at an 8 mA test current and a maximum reverse leakage current of 500 nA. The component is RoHS compliant, as denoted by the 'e3' suffix, and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High voltage protection systems utilizing robust surge handling capabilities
• Industrial equipment operating under wide ambient temperature conditions

Procurement Notes

Verify that the specific part number includes the 'e3' suffix to confirm RoHS compliance and matte-tin plating. Ensure the 'TR12' suffix matches the required tape and reel packaging format. Confirm the 'A' suffix corresponds to the necessary ±10% voltage tolerance for your design specifications. Cross-reference the manufacturer's latest documentation to ensure no obsolescence notices or engineering change orders affect availability or electrical parameters.

Selection Notes

Select this component when a 150 V Zener voltage with ±10% tolerance is required for through-hole mounting. The T-18 package provides adequate thermal performance for 5-watt dissipation with proper heat sinking. Consider the low thermal resistance junction-to-lead characteristic for high-current applications. Verify that the moisture classification Level 1 meets storage requirements without dry pack constraints.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi. The series covers a voltage selection from 3.3 to 200 volts with various tolerance options identified by suffix letters. These plastic encapsulated diodes are JEDEC registered and offer military equivalent screening levels via specific prefixes. The e3 designation indicates environmental compliance with restricted hazardous substances.

Replacement Considerations

Consult official datasheets for direct substitutes within the 1N5333-5388B series. Equivalent parts must match the 150 V rating, 5 W power dissipation, and T-18 package dimensions. Verify that any replacement maintains the same voltage tolerance and thermal characteristics.
