1N5337BRLG

Single Zener Diodes Overview

The onsemi 1N5337BRLG is a 5 Watt Zener voltage regulator diode belonging to the 1N53 Series. It features a nominal Zener voltage of 4.7 V with a ±5% tolerance, tested at a current of 260 mA. The device utilizes silicon-oxide passivated junctions within an axial lead Surmetic 40 (DO-15) plastic package. Key electrical parameters include a maximum Zener impedance of 2 Ω and a reverse leakage current of 5 μA. It operates within a temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
• Provides tight limits on up to six electrical parameters to ensure consistent performance.
• Features high surge rating capability of up to 180 W for an 8.3 ms pulse duration.
• Offers ESD protection rated at Class 3 (>16 kV) per the Human Body Model.

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'RLG' corresponds to the tape and reel packaging format containing 4000 units per reel. Confirm the presence of the 'G' suffix indicates a Pb-Free package compliant with relevant standards. Ensure the component matches the Surmetic 40 case outline specifications during physical inspection.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V reference with 5 W power dissipation is required. The axial lead configuration allows for through-hole mounting in any position. Consider the thermal resistance characteristics and derating requirements above 25°C ambient temperature to maintain reliability under steady-state conditions.

Single Zener Diodes Part Context

This part belongs to the 1N53 Series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V. The 1N5337B variant specifically targets the 4.7 V nominal value. The 'RLG' designation distinguishes it from box-packaged versions by indicating reel-based distribution.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5337B specification. Verify that substitute parts match the 5 W power rating, 4.7 V nominal voltage, and DO-15 axial lead package dimensions to ensure mechanical compatibility.
