1N5386BG

Overview

The onsemi 1N5386BG is a silicon Zener voltage regulator diode belonging to the 1N53 Series. It provides a nominal reverse Zener voltage of 180 V with a tolerance of ±5%. The device features a maximum steady-state power dissipation of 5 W at a lead temperature of 25°C and operates within a junction-to-lead thermal resistance of 25 °C/W. Electrical characteristics include a test current (IZT) of 5 mA, a maximum Zener impedance (ZZT) of 430 Ω, and a maximum reverse leakage current (IR) of 500 nA at 130 V. The component utilizes an axial lead Surmetic 40 package (Case 017AA) and supports an operating temperature range from -65°C to +200°C.

Feature Summary

• Utilizes silicon-oxide passivated junctions for improved operating characteristics and environmental protection.
• Features a void-free, transfer-molded thermosetting plastic package that offers corrosion resistance and solderability.
• Provides high surge capability with ratings up to 180 W for non-repetitive pulses of 8.3 ms duration.
• Includes robust electrostatic discharge (ESD) protection rated at Class 3 (>16 kV) per the Human Body Model.

Applications

• Voltage regulation in electronic circuits requiring stable reference voltages.
• Protection against overvoltage conditions and transient spikes in power supplies.
• Clamping applications for safeguarding sensitive components from excessive voltage levels.

Procurement Notes

Verify the specific ordering suffix 'G' confirms the package is Pb-Free as indicated in the datasheet. Confirm the required packaging format matches your assembly needs, as the standard box quantity is 1000 units. Ensure the application environment stays within the specified thermal limits to maintain reliability. Check for any RoHS or REACH compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a precise 180 V regulation point is required with tight tolerance limits. The 5 W power rating allows for significant current handling compared to lower-power alternatives. Consider the axial lead configuration for through-hole mounting requirements. Evaluate the thermal resistance characteristics to ensure adequate heat sinking or lead length management for continuous operation.

Part Context

This device is part of the comprehensive 1N53 Series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, offering standardized JEDEC type numbers with consistent mechanical dimensions. The 1N5386BG specifically addresses the higher voltage segment of this lineup, sharing common package styles and electrical testing methodologies with its siblings.

Replacement Considerations

Compatible replacements include other manufacturers' equivalents such as the Microsemi 1N5386B or generic 1N5386 variants. Verify that substitute parts match the 180 V nominal voltage, 5 W power dissipation, and Case 017AA physical dimensions. Ensure the replacement maintains the same ±5% tolerance and electrical parameters for direct interchangeability.
