1N5384BRLG

Overview

The onsemi 1N5384BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, designed for robust performance in axial lead applications. It features a nominal Zener voltage of 160 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device utilizes silicon-oxide passivated junctions within a void-free, transfer-molded plastic package (CASE 017AA). Key electrical parameters include a test current of 8 mA, a maximum Zener impedance of 350 Ω, and a reverse leakage current of 1 µA at 152 V. It supports an operating temperature range from -65°C to +200°C.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight parameter limits.
• Features surge rating capability of up to 180 W at 8.3 ms pulse width for transient protection.
• Provides ESD protection rated at Class 3 (>16 kV) per the Human Body Model.
• Encased in a corrosion-resistant, transfer-molded plastic package suitable for various mounting positions.

Applications

• Voltage regulation in high-power electronic circuits
• Transient voltage suppression requiring high surge ratings
• Reference voltage sources in industrial equipment

Procurement Notes

Verify that the ordering suffix matches the required packaging configuration. The 'RL' suffix indicates availability in tape and reel format containing 4000 units, while other suffixes may denote bulk box quantities. Confirm RoHS compliance status if environmental regulations apply to the specific manufacturing batch. Ensure the component marking aligns with the requested part number before integration into production workflows.

Selection Notes

Select this component when a stable 160 V reference is required with high power handling capabilities. The 5 W dissipation rating allows for significant current handling compared to lower-power alternatives. Consider the thermal resistance characteristics and ambient operating temperatures to ensure the junction temperature remains within safe limits during continuous operation.

Part Context

This device belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, offering consistent mechanical and electrical specifications across all variants. The 1N5384B specifically targets applications needing precise high-voltage regulation with reliable performance under varying thermal conditions.

Replacement Considerations

Compatible substitutes within the same family include the 1N5383B and 1N5386B, which share identical mechanical dimensions and power ratings but differ in nominal Zener voltage. Verify that the alternative voltage rating meets the circuit requirements before substitution.
