1N5335BRLG

Single Zener Diodes Overview

The onsemi 1N5335BRLG is a silicon-oxide passivated Zener voltage regulator diode from the 1N53 Series, housed in an axial lead Surmetic 40 (DO-15) plastic package. It provides a nominal reverse Zener voltage of 3.9 V with a ±5% tolerance. The device supports a maximum steady-state power dissipation of 5 W at 25°C and operates within a junction temperature range of -65°C to +200°C. Key electrical parameters include a test current of 320 mA, a maximum Zener impedance of 2 Ω, and a maximum reverse leakage current of 50 μA.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
• Offers high surge rating capability up to 180 W for an 8.3 ms pulse width.
• Features a robust transfer-molded plastic package resistant to corrosion and moisture.
• Provides guaranteed maximum limits on multiple electrical parameters including impedance and leakage.

Single Zener Diodes Applications

• Voltage regulation across broad operating current and temperature ranges
• Protection against high surge stresses in electronic circuits
• General purpose voltage reference applications

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 Pb-Free designation if required by specific manufacturing standards. Ensure the component matches the JEDEC registered 1N5335B type number with the B suffix indicating the specified ±5% voltage tolerance.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V Zener voltage with tight tolerance is required in a high-power axial lead configuration. The 5 W power rating allows operation at high DC currents provided adequate heat sinking is implemented. Consider the thermal resistance characteristics and the specific test conditions for impedance and leakage when designing the circuit.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of 5 Watt Zener diodes manufactured by onsemi. The series covers a voltage selection from 3.3 V to 200 V. These devices are designed for applications requiring reliable voltage regulation in common environmental conditions using standard axial lead mounting techniques.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' versions of the 1N5335B or 1N5335BRLG. Verify that any replacement maintains the same 5 W power dissipation, DO-15 package dimensions, and ±5% voltage tolerance specifications.
