1N5339BG

Single Zener Diodes Overview

The onsemi 1N5339BG is a silicon-oxide passivated junction Zener voltage regulator diode belonging to the 1N53 Series. It operates in an axial lead Surmetic 40 (CASE 017AA) plastic package with a maximum steady-state power dissipation of 5 W at a lead temperature of 25°C. The nominal reverse Zener voltage is 5.6 V, with a tolerance range of 5.32 V to 5.88 V. Key electrical parameters include a test current of 220 mA, a maximum Zener impedance of 1 Ω at IZT and 2 Ω at IZK, and a maximum reverse leakage current of 1 µA at VR. The device supports a maximum DC Zener current of 865 mA and withstands a surge rating of up to 180 W for 8.3 ms pulses.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junction technology for tight limits and superior operating characteristics.
• Features void-free, transfer-molded thermosetting plastic packaging that provides corrosion resistance and protection in common environmental conditions.
• Offers high ESD protection rated at Class 3 (>16 kV) per the Human Body Model.
• Guarantees maximum limits on up to six distinct electrical parameters.

Single Zener Diodes Applications

• Voltage regulation across broad operating current and temperature ranges.
• Protection against electrostatic discharge (ESD) events.
• Handling high non-repetitive surge currents in transient conditions.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'G' confirms the package is Pb-Free as indicated in the datasheet nomenclature. Confirm the component utilizes the standard CASE 017AA axial lead configuration. Ensure compliance with the specified thermal derating requirements above 25°C to maintain the 5 W power dissipation limit. Validate that the application environment does not exceed the maximum junction temperature of 150°C under DC conditions.

Single Zener Diodes Selection Notes

Select this component when a precise 5.6 V reference or regulation point is required within a 5 W power envelope. The ±5% tolerance suits applications needing tighter voltage accuracy than standard general-purpose Zeners. Consider the low dynamic impedance for stable regulation under varying load currents. Evaluate the thermal resistance characteristics if heat sinking or specific lead lengths are necessary for the target circuit design.

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 wide voltage selection from 3.3 V to 200 V. All devices in this family share the same Surmetic 40 axial lead package and utilize silicon-oxide passivation. The 'B' designation indicates a JEDEC registered type with a ±5% voltage tolerance.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5339B specification. Verify that any substitute matches the 5.6 V nominal voltage, 5 W power rating, and CASE 017AA physical dimensions. Ensure the replacement maintains equivalent Zener impedance and leakage current limits for the intended circuit performance.
