1N5339B

Single Zener Diodes Overview

The onsemi 1N5339B is a silicon-oxide passivated junction Zener voltage regulator diode rated for 5 watts of steady-state power dissipation. It features a nominal Zener voltage of 5.6 V with a ±5% tolerance, tested at a current of 220 mA. The device exhibits a maximum dynamic impedance of 1 Ω and a reverse leakage current of 1 μA at 2 V. Packaged in an axial lead Surmetic 40 (DO-15) plastic case, it supports a wide operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior electrical characteristics and environmental protection.
• Provides high surge capability with ratings up to 180 W for 8.3 ms pulses.
• Features robust ESD protection exceeding 16 kV according to the Human Body Model standard.

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages.
• Overvoltage protection for sensitive electronic components.
• Clamping applications in industrial equipment power supplies.

Single Zener Diodes Procurement Notes

Verify that the specific order suffix matches the required package type and compliance status. Confirm whether the 'G' suffix is necessary for lead-free specifications. Ensure the ordering code aligns with the desired shipping quantity, such as box or tape-and-reel formats, before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference with tight tolerance is required in a through-hole configuration. Evaluate thermal management needs carefully, as the 5 W rating depends on adequate heat sinking and derating above 25°C. Consider the low dynamic impedance for precise regulation requirements.

Single Zener Diodes Part Context

This part belongs to the 1N53 Series, a complete lineup of 5 Watt Zener diodes covering a voltage range from 3.3 V to 200 V. The series utilizes transfer-molded plastic packages designed to withstand common environmental conditions while maintaining reliable performance across various industrial and commercial applications.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the JEDEC 1N5339B specification. Verify that substitute parts maintain the same 5 W power rating, DO-15 package dimensions, and ±5% voltage tolerance to ensure circuit compatibility.
