1N5375B

Overview

The onsemi 1N5375B is a silicon Zener diode with an 82 V nominal voltage and ±5% tolerance. It operates in a DO-15 axial lead package (CASE 017AA) with a 5 W maximum power dissipation at 25°C. Key electrical parameters include a test current of 15 mA, a maximum dynamic impedance of 65 Ω, and a reverse leakage current of 1.8 µA at the breakdown voltage. The device supports a junction temperature range from -65°C to +200°C.

Feature Summary

• Utilizes silicon-oxide passivated junctions for tight limits and improved operating characteristics.
• Features void-free, transfer-molded thermosetting plastic packaging resistant to corrosion.
• Provides high surge capability with ratings up to 180 W for non-repetitive pulses.

Applications

• Voltage regulation circuits requiring stable reference voltages.
• Protection against transient overvoltage events in electronic systems.
• General-purpose clamping applications within specified thermal limits.

Procurement Notes

Verify the specific ordering suffix when purchasing. The 'G' suffix indicates a Pb-Free package, while standard versions may contain lead. Confirm that the required package type matches the intended manufacturing process, as bulk boxes and tape-and-reel options are available for different assembly needs.

Selection Notes

Select this component based on the precise 82 V requirement and the need for robust surge handling. Ensure the application circuit can maintain the lead temperature below 25°C to achieve the full 5 W rating, or apply appropriate derating factors for higher ambient temperatures to prevent thermal damage.

Part Context

This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V, offering consistent performance across various industrial and commercial applications through standardized axial lead packages.

Replacement Considerations

Cross-reference with other manufacturers' 1N5375B equivalents. Verify that substitute parts match the 82 V nominal voltage, 5 W power rating, and DO-15 package dimensions to ensure mechanical and electrical compatibility.
