1N5339BRLG

Single Zener Diodes Overview

The onsemi 1N5339BRLG is a single-channel 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 5.6 V with a tolerance of ±5%. The device features 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. Electrical characteristics include a test current of 220 mA, a maximum Zener impedance of 1 Ω, and a maximum reverse leakage current of 1 μA.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight parameter limits.
• Features a void-free, transfer-molded thermosetting plastic package that offers corrosion resistance and protection in common environmental conditions.
• Provides high surge capability with a rating of up to 180 W for an 8.3 ms pulse width.

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages.
• Protection against transient overvoltage events in electronic systems.
• General-purpose rectifier and switching applications.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'RLG' corresponds to the tape and reel packaging format containing 4000 units per reel. Confirm that the 'G' suffix indicates compliance with Pb-Free standards as defined by the manufacturer's soldering guidelines. Ensure the component meets RoHS requirements if applicable to your manufacturing process. Cross-reference the datasheet revision date to confirm the electrical parameters match your design specifications.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference with ±5% tolerance is required in a high-power axial package. The 5 W power dissipation rating allows for operation without external heat sinks under moderate load conditions at ambient temperatures up to 25°C. Consider the low dynamic impedance of 1 Ω for applications demanding precise voltage stability. Verify thermal derating calculations are performed if operating above 25°C ambient temperature.

Single Zener Diodes Part Context

This part belongs to the 1N53xxB 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 mechanical Surmetic 40 case outline. The 'B' designation specifically denotes a ±5% voltage tolerance, distinguishing it from other tolerance variants within the broader 1N53 family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5339B devices in the DO-15 package. Verify that replacement parts maintain the 5 W power rating, 5.6 V nominal voltage, and ±5% tolerance. Ensure the alternative component supports the required 200°C maximum junction temperature and similar surge current capabilities.
