1N5334BG

Single Zener Diodes Overview

The onsemi 1N5334BG is a 5 Watt Zener voltage regulator from the 1N53 Series, housed in an axial lead Surmetic 40 (CASE 017AA) plastic package. It features silicon-oxide passivated junctions for superior environmental protection and tight electrical limits. The nominal Zener voltage is 3.6 V with a ±5% tolerance range of 3.42 V to 3.78 V at a test current of 350 mA. Key electrical parameters include a maximum Zener impedance of 2.5 Ohms at IZT, a reverse leakage current of 1 µA at VR = 18.7 V, and a maximum DC Zener current (IZM) of 1320 mA. The device supports a maximum steady-state power dissipation of 5 W at 25°C, derating linearly above this temperature. Operating temperatures range from -65°C to +200°C, with a maximum junction-to-lead thermal resistance of 25°C/W.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for enhanced reliability and environmental protection within an axial lead transfer-molded plastic package.
• Provides tight manufacturing tolerances with guaranteed maximum limits on multiple electrical parameters including voltage, impedance, and leakage.
• Offers high surge capability with ratings up to 180 W for 8.3 ms pulses, suitable for transient protection applications.

Single Zener Diodes Applications

• Voltage regulation in power supply circuits requiring stable reference voltages.
• Transient voltage suppression and overvoltage protection in electronic systems.
• Clamping applications in signal processing and communication equipment.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'G' indicates a Pb-Free package configuration as per onsemi standards. Confirm the package type matches the required Surmetic 40 axial lead form factor. Ensure compatibility with RoHS and REACH regulatory requirements for your target market. Check for any specific handling or soldering guidelines provided in the manufacturer's mounting techniques manual.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V Zener reference with 5 W power handling is required. Consider the ±5% tolerance if precise voltage accuracy is critical. Evaluate the thermal environment to ensure proper heat dissipation, as power must be derated above 25°C. Compare impedance and leakage specifications against other series members if lower noise or tighter limits are needed.

Single Zener Diodes Part Context

The 1N5334BG belongs to the broader 1N53 Series of 5 Watt Zener diodes manufactured by onsemi. This series covers a wide voltage range from 3.3 V to 200 V, sharing common mechanical characteristics and packaging standards. The 'B' designation typically denotes a ±5% tolerance, while the 'G' suffix specifies Pb-Free compliance. These devices are designed for general-purpose industrial and commercial applications requiring robust voltage regulation.

Single Zener Diodes Replacement Considerations

Direct replacements within the same family include other 1N53xxB variants with similar voltage ratings, though exact substitution requires matching the specific Zener voltage and power dissipation limits. Cross-manufacturer equivalents should be verified for pinout compatibility, thermal resistance, and electrical parameter alignment with the original datasheet specifications.
