BZX584B3V3

Single Zener Diodes Overview

The BZX584B3V3 is a surface-mount Zener diode manufactured by Taiwan Semiconductor Corporation, designed for general voltage regulation applications. It operates within the BZX584B series, which covers nominal voltages from 2.4 V to 75 V with a strict ±2% tolerance. The device is housed in an SOD-523F package and features a maximum power dissipation of 150 mW at 25°C ambient temperature. Key electrical specifications include a nominal Zener voltage of 3.3 V tested at 5 mA, a typical impedance of 95 Ω at the test current, and a leakage current of 5 µA maximum at 1 V reverse voltage.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a tight ±2% Zener voltage tolerance.
• Utilizes an ultra-small SOD-523F surface-mount package for compact board layouts.
• Complies with RoHS standards and is halogen-free according to IEC 61249-2-21.
• Features matte tin-plated terminals that are solderable per J-STD-002.

Single Zener Diodes Applications

• General voltage regulation functions
• Reference voltage generation in low-power circuits
• Over-voltage protection for sensitive components

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the component meets the required moisture sensitivity level (MSL 1) and flammability rating (UL 94V-0) for your assembly process. Cross-reference the datasheet version D2007 to validate all electrical parameters before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 3.3 V is required with high precision. The ±2% tolerance makes it suitable for applications where standard 5% or 10% Zener diodes introduce unacceptable error margins. Ensure the circuit design accounts for the 150 mW power dissipation limit and the thermal resistance characteristics provided in the datasheet.

Single Zener Diodes Part Context

This part belongs to the BZX584B series of low-power voltage regulator diodes produced by Taiwan Semiconductor. The series offers a wide selection of nominal working voltages ranging from 2.4 V up to 75 V. All devices in this family share the same SOD-523F mechanical footprint and similar thermal characteristics, allowing for consistent design practices across different voltage requirements.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the SOD-523F package, 3.3 V nominal voltage, and ±2% tolerance. Verify that alternative manufacturers provide equivalent power dissipation ratings and leakage current specifications to maintain circuit performance integrity.
