1N5375BG

Overview

The onsemi 1N5375BG is a silicon-oxide passivated junction Zener diode rated for 5 watts of steady-state power dissipation. It provides an 82 V nominal Zener voltage with a ±5% tolerance and operates within a temperature range of -65°C to +200°C. The device utilizes an axial lead Surmetic 40 package (Case 017AA) and features a maximum reverse leakage current of 500 nA at the breakdown voltage.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics
• Provides high surge rating capability up to 180 W at 8.3 ms pulse width
• Encapsulated in void-free, transfer-molded thermosetting plastic for environmental protection

Applications

• Voltage regulation circuits requiring 5W power handling
• Surge protection applications utilizing high peak current ratings
• General purpose electronic designs compatible with axial lead mounting

Procurement Notes

Verify compliance with RoHS directives and REACH SVHC requirements prior to integration. Confirm that the Pb-Free suffix designation aligns with specific soldering and mounting techniques outlined in the manufacturer's reference manual. Ensure thermal management strategies account for the specified junction-to-lead thermal resistance values under continuous DC conditions.

Selection Notes

Select this component when a robust 5W axial Zener regulator is required for voltages near 82V. The tight electrical parameter limits and oxide passivation make it suitable for demanding environments. Consider the specific test currents and impedance values provided in the datasheet tables to ensure compatibility with the target circuit's biasing requirements.

Part Context

This part 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 various tolerances identified by specific suffix letters. The 1N5375BG specifically represents the 82 V variant within this comprehensive lineup of axial-leaded devices.

Replacement Considerations

Cross-reference with other manufacturers' 1N5375 equivalents or generic 5W 82V Zener diodes. Verify that substitute components meet the same 5W power dissipation, 82V nominal voltage, and ±5% tolerance specifications to maintain circuit performance integrity.
