1N5366BG

Overview

The onsemi 1N5366BG is a silicon-oxide passivated junction Zener voltage regulator diode from the 1N53 Series. It operates in an axial lead Surmetic 40 package (Case 017AA) with a nominal reverse Zener voltage of 39 V and a maximum steady-state power dissipation of 5 W at 25°C. The device features a ±5% tolerance, a maximum Zener impedance of 14 Ω at a test current of 30 mA, and a maximum reverse leakage current of 500 nA at 30 V. It supports a maximum DC Zener current of 122 mA and withstands surge currents up to 180 W for 8.3 ms pulses.

Feature Summary

• Utilizes silicon-oxide passivated junction technology for superior operating characteristics and environmental protection.
• Provides tight electrical limits guaranteed across multiple parameters including voltage, impedance, and leakage.
• Features high surge capability rated up to 180 W for short-duration non-repetitive pulses.

Applications

• Voltage regulation in electronic circuits requiring stable reference levels.
• Protection against transient overvoltage events via surge absorption.
• General-purpose clipping and clamping applications in signal processing.

Procurement Notes

Verify that the ordering suffix 'G' corresponds to the Pb-Free package specification as defined by the manufacturer. Confirm the specific package variant matches the required mechanical dimensions for the intended mounting position. Ensure compliance with RoHS directives if applicable to the target market. Cross-reference the document number 98AON21393DD for the most current datasheet details before finalizing procurement specifications.

Selection Notes

Select this component when a 39 V regulation point is required within the 5 Watt power dissipation class. The axial lead configuration allows for through-hole mounting in any orientation. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure the junction temperature remains within the specified operating range 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 Zener voltage range from 3.3 V to 200 V, all housed in the same transfer-molded plastic axial lead package. The 1N5366BG specifically addresses the 39 V segment of this comprehensive lineup.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative manufacturers offering similar 5W axial Zener diodes with equivalent voltage and impedance specifications.
