1N5336BG

Single Zener Diodes Overview

The onsemi 1N5336BG is a silicon-oxide passivated junction Zener diode rated for 5 W steady-state power dissipation. It provides a nominal reverse Zener voltage of 4.3 V with a ±5% tolerance, tested at 290 mA. The device features a maximum Zener impedance of 2 Ω and a maximum reverse leakage current of 10 µA. It operates within a temperature range of -65 °C to +150 °C (DC) or +200 °C (pulsed). Packaged in an axial lead Surmetic 40 (Case 017AA) plastic enclosure, it offers Class 3 ESD protection (>16 kV HBM) and supports surge currents up to 180 W for 8.3 ms pulses.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for tight electrical limits and superior operating characteristics.
• Provides robust environmental protection through a void-free, transfer-molded thermosetting plastic package.
• Features high surge capability and excellent ESD resistance per Human Body Model standards.

Single Zener Diodes Applications

• Voltage regulation across broad operating current and temperature ranges.
• Protection against transient overvoltage events in electronic circuits.
• Reference voltage generation in precision measurement systems.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'G' confirms Pb-Free packaging status as indicated in the datasheet. Confirm the component matches the JEDEC registered 1N5336B designation with the B-suffix indicating ±5% tolerance. Ensure the procurement documentation references the correct Case 017AA mechanical outline for mounting compatibility.

Single Zener Diodes Selection Notes

Select this component when a 4.3 V reference point is required with 5 W thermal handling capabilities. The axial lead configuration allows for flexible mounting positions. Consider the low thermal resistance design which permits operation at high DC currents provided adequate heat sinking is implemented according to the derating curves.

Single Zener Diodes Part Context

This part belongs to the 1N53 Series, a complete line of 5 Watt Zener voltage regulators manufactured by onsemi. The series spans from 3.3 V to 200 V, utilizing standardized JEDEC type numbers. The 1N5336BG specifically addresses applications requiring stable regulation near the lower end of the voltage spectrum while maintaining high power dissipation capacity.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' equivalents meeting the 1N5336B specification. Verify that replacement parts maintain the same 5 W power rating, 4.3 V nominal voltage, and ±5% tolerance to ensure circuit performance consistency without redesigning the thermal management system.
