1N5369BRLG

Overview

The onsemi 1N5369BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, housed in an axial lead DO-15 (Surmetic 40) package. It features a nominal Zener voltage of 51 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device operates within a temperature range of -65°C to +200°C. Key electrical parameters include a test current of 25 mA, a maximum Zener impedance of 27 Ω, and a maximum reverse leakage current of 500 nA.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight parameter limits.
• Features void-free, transfer-molded thermosetting plastic packaging that provides corrosion resistance and environmental protection.
• Offers high surge capability with ratings up to 180 W for 8.3 ms pulses.
• Includes ESD protection rated at Class 3 (>16 kV) per the Human Body Model.

Applications

• Voltage regulation circuits requiring stable reference voltages.
• Overvoltage protection systems utilizing high surge current handling.
• General-purpose electronic equipment operating under harsh environmental conditions.

Procurement Notes

Verify the specific ordering suffix 'RLG' against official documentation to confirm tape and reel packaging specifications and quantity. Ensure compatibility with RoHS directives if required by the application. Confirm that the component meets all relevant safety standards and certifications applicable to the intended deployment environment before finalizing procurement.

Selection Notes

Select this component when a 51 V Zener voltage with ±5% tolerance is required alongside a 5 W power rating. The DO-15 package is suitable for through-hole mounting where higher thermal dissipation is needed compared to smaller packages. Consider the wide operating temperature range and robust surge capabilities for demanding applications.

Part Context

This part belongs to the 1N53 Series, a comprehensive line of 5 Watt Zener diodes manufactured by onsemi. The series covers a broad Zener voltage range from 3.3 V to 200 V, offering consistent performance across various voltage levels. The 1N5369BRLG specifically addresses the 51 V segment within this family, providing standardized axial lead components for industrial and commercial electronics.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N5369B specification. Verify that any substitute maintains the same 5 W power rating, 51 V nominal voltage, ±5% tolerance, and DO-15 package dimensions to ensure mechanical and electrical compatibility without circuit redesign.

FAQ

What is the maximum non-repetitive surge current rating for the 1N5369BRLG?

The datasheet specifies a surge rating of up to 180 W for an 8.3 ms pulse width. The peak surge current value varies based on the specific Zener voltage and can be determined using the provided logarithmic charts in the technical documentation.

How does the 'RLG' suffix affect the component's function?

The 'RLG' suffix indicates the packaging configuration, specifically a tape and reel format containing 4000 units. It does not alter the electrical characteristics or functionality of the diode compared to the box-packaged version.
