1N5366BRLG

Overview

The onsemi 1N5366BRLG is a single-channel Zener voltage regulator diode from the 1N53 series, featuring a nominal reverse Zener voltage of 39 V with a ±5% tolerance. It operates within a test current range of 25 mA to 30 mA and exhibits a maximum Zener impedance of 14 Ω at the test current. The device supports a maximum steady-state power dissipation of 5 W at 25°C lead temperature, with a junction-to-lead thermal resistance of 25 °C/W. It withstands a maximum non-repetitive surge current of up to 180 W for an 8.3 ms pulse width. The component utilizes a Surmetic 40 axial lead package (Case 017AA) and offers an operating temperature range from -65°C to +200°C.

Feature Summary

• Utilizes silicon-oxide passivated junction technology for superior electrical characteristics and tight parameter limits.
• Features robust surge handling capabilities rated up to 180 W for short-duration pulses.
• Includes high electrostatic discharge protection exceeding 16 kV per the Human Body Model standard.

Applications

• Voltage regulation in electronic circuits requiring stable reference voltages.
• Protection against transient overvoltage events in power supply lines.
• Clamping applications for safeguarding sensitive semiconductor components.

Procurement Notes

Verify that the ordering suffix 'RLG' corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm compliance with RoHS directives and ensure the supplier provides valid traceability documentation for the Pb-Free manufacturing process. Cross-reference the manufacturer part number with official datasheets to validate the exact electrical tolerances and package dimensions before finalizing procurement orders.

Selection Notes

Select this component when a precise 39 V reference is needed with a 5 W power rating. Ensure the application environment remains within the specified -65°C to +200°C temperature range. Verify that the circuit design accommodates the 14 Ω maximum dynamic impedance to maintain desired regulation accuracy. Consider the axial lead format for through-hole mounting requirements.

Part Context

This device belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series encompasses a wide voltage range from 3.3 V to 200 V, all housed in transfer-molded plastic packages designed for environmental protection. The 1N5366BRLG specifically addresses the 39 V segment of this comprehensive lineup.

Replacement Considerations

Compatible substitutes include other manufacturers' equivalents meeting the 1N5366B specification, such as the 1N5366B from Micro Commercial Components or generic 1N5366 variants. Ensure any replacement maintains the 5 W power dissipation, 39 V nominal voltage, and ±5% tolerance to guarantee functional interchangeability.
