1N5384B

Overview

The onsemi 1N5384B is a 5 Watt Zener diode featuring silicon-oxide passivated junctions housed in an axial lead, transfer-molded plastic package. It provides a nominal reverse Zener voltage of 160 V with a ±5% tolerance range spanning from 152 V to 168 V. The device operates within a temperature range of -65°C to +200°C and includes surge protection capabilities rated up to 180 W for 8.3 ms pulses.

Feature Summary

• Utilizes silicon-oxide passivated junction technology for improved operating characteristics
• Features void-free, transfer-molded thermosetting plastic case construction
• Includes built-in strain relief and corrosion-resistant external surface finishes

Applications

• Voltage regulation circuits requiring high power dissipation
• Overvoltage protection for industrial equipment inputs
• Surge suppression in power supply systems

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard 'G' suffix indicates a Pb-Free package variant. Confirm availability status as older manufacturing runs may be discontinued or replaced by updated revisions. Ensure compliance with RoHS directives if required for the target application environment.

Selection Notes

Select this component for applications demanding robust transient handling and stable voltage reference at higher voltages. Consider the thermal resistance characteristics and derating requirements above 75°C to ensure reliable operation under continuous load conditions without exceeding maximum junction temperatures.

Part Context

This part belongs to the 1N53xxB series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage spectrum from 3.3 V to 200 V, offering consistent mechanical and electrical performance across different breakdown voltage options within the same axial lead package family.

Replacement Considerations

Cross-reference with other manufacturers' 1N5384 equivalents. Verify that substitute parts match the 160 V nominal voltage, 5 W power rating, and T-18/DO-41 axial lead dimensions to maintain compatibility with existing board layouts and thermal management designs.
