BZX585-B3V9,115

Single Zener Diodes Overview

The Nexperia BZX585-B3V9,115 is a general-purpose Zener diode housed in an SOD523 (SC-79) ultra-small flat lead Surface-Mounted Device plastic package. It provides a nominal working voltage of 3.9 V with a tolerance range of 3.82 V to 3.98 V. The device supports a total power dissipation of up to 300 mW and features a non-repetitive peak reverse power dissipation capability of 40 W. Electrical characteristics include a maximum forward voltage of 1.1 V at 100 mA, a maximum reverse current of 400 µA, and a differential resistance of 85 Ω at a test current of 5 mA.

Single Zener Diodes Feature Summary

• Encapsulated in an ultra-small SOD523 plastic surface-mounted package for high-density circuit designs.
• Offers low differential resistance to support stable voltage regulation performance.
• Provides a wide operating temperature range suitable for diverse environmental conditions.

Single Zener Diodes Applications

• General regulation functions
• Voltage reference applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required packaging format before procurement. Confirm that the component meets all necessary automotive or industrial qualification standards if applicable to the target design. Ensure compatibility with standard reflow soldering profiles for the SOD523 package type during assembly planning.

Single Zener Diodes Selection Notes

Select this component when a precise 3.9 V reference is required within a compact footprint. Consider the ±2% tolerance series for tighter voltage accuracy compared to the standard ±5% variant. Evaluate thermal constraints based on the 300 mW dissipation limit and ambient operating temperatures ranging from -65 °C to +150 °C.

Single Zener Diodes Part Context

This part belongs to the Nexperia BZX585 series, which comprises 74 types covering nominal voltages from 2.4 V to 75 V. The series utilizes the standardized E24 voltage range and is available in two distinct tolerance configurations. All variants share the same SOD523 package dimensions and pinout configuration for interchangeability within design constraints.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include BZX585-C3V9,115, which offers identical electrical parameters but with a wider ±5% voltage tolerance instead of the ±2% tolerance found in the B-series variant.
