1N5343BRLG

Single Zener Diodes Overview

The onsemi 1N5343BRLG is a 5 Watt Zener voltage regulator from the 1N53 Series, housed in an axial lead Surmetic 40 package (Case 017AA). It features a nominal Zener voltage of 7.5 V with a ±5% tolerance and a maximum reverse leakage current of 10 µA at 5.7 V. The device operates within a junction temperature range of -65°C to +200°C and offers an ESD rating exceeding 16 kV per the Human Body Model. Electrical characteristics are guaranteed across multiple parameters, including impedance and surge ratings.

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 capability rated up to 180 W for 8.3 ms pulses.

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 'RL' corresponds to the tape and reel packaging format specified in the datasheet. Confirm the presence of the 'G' suffix if lead-free compliance is required by your assembly process. Ensure the component marking matches the specific device number for traceability.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V reference with 5 W power dissipation is needed. The axial lead configuration allows for through-hole mounting. Consider the thermal resistance and derating requirements above 25°C to maintain reliability under continuous load 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, all sharing the same robust Surmetic 40 axial lead package design for consistent mechanical and thermal performance across different voltage ratings.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5343B equivalents or onsemi's 1N5343BG variant. Verify that any replacement maintains the same 5 W power rating, 7.5 V nominal voltage, and axial lead form factor to fit existing board layouts.
