Product details
Overview
BZX584B3V3 RSG from Taiwan Semiconductor is a surface-mount Zener diode with nominal 3.3 V zener voltage, ±2% tolerance, 150 mW power dissipation, and SOD-523F package. It provides precise voltage regulation in low-power biasing, reference, and protection circuits for portable and space-constrained electronics.
For engineers reviewing the BZX584B3V3 RSG datasheet, BZX584B3V3 RSG pinout, BZX584B3V3 RSG application, or BZX584B3V3 RSG equivalent, key selection criteria include its 3.23–3.37 V zener range at 5 mA test current, 95 Ω typical zener impedance, -3.5 mV/°C temperature coefficient, and moisture sensitivity level 1 compliance.
Technical Context
The BZX584B3V3 RSG operates as a single-die, cathode-banded Zener diode optimized for stable reverse-breakdown regulation under low-current conditions (IZT = 5 mA). Its thermal resistance of 833 °C/W and junction temperature limit of +150 °C support reliable operation in ambient temperatures up to +125 °C when derated per the admissible power curve.
Designed for SOD-523F footprint compatibility, it delivers tight voltage control with 1.0 µA leakage at VR = 1.0 V and 5 µA maximum leakage at rated zener voltage - critical for low-quiescent-current voltage references and precision clamping in signal conditioning paths.

FAQ
What is the exact zener voltage range specified for BZX584B3V3 RSG at 5 mA test current?
The BZX584B3V3 RSG has a guaranteed zener voltage range of 3.23 V to 3.37 V when tested at IZT = 5 mA, reflecting its ±2% tolerance around the nominal 3.3 V rating. This range is explicitly defined in the Electrical Specifications table of the Taiwan Semiconductor datasheet Version D2007 and applies directly to the BZX584B3V3 RSG device.
Is BZX584B3V3 RSG compatible with lead-free reflow soldering processes?
Yes, BZX584B3V3 RSG features matte tin-plated leads compliant with J-STD-002 for solderability and is qualified for standard lead-free reflow profiles (peak temperature ≤ 260 °C). Its moisture sensitivity level 1 rating eliminates pre-bake requirements, supporting direct placement into high-throughput SMT lines without process modification.
What is the maximum leakage current specification for BZX584B3V3 RSG, and at what reverse voltage is it measured?
The maximum leakage current for BZX584B3V3 RSG is 5 µA, measured at VR = 1.0 V. This value is confirmed in the Electrical Specifications table under "LEAKAGE CURRENT" for the BZX584B3V3 row. It reflects the device's ability to maintain high impedance in non-conducting state - critical for low-power bias networks.
Does BZX584B3V3 RSG have a specified temperature coefficient, and how does it affect circuit performance?
Yes, BZX584B3V3 RSG has a typical temperature coefficient of -3.5 mV/°C, meaning its zener voltage decreases by approximately 3.5 mV per degree Celsius rise in junction temperature. This coefficient is documented in the Electrical Specifications table and must be accounted for in precision reference designs operating across wide temperature ranges.
What packaging option is used for BZX584B3V3 RSG, and how many units are supplied per reel?
BZX584B3V3 RSG is supplied in SOD-523F package on 8,000-piece 7-inch reels, as specified in the Ordering Information section of the Taiwan Semiconductor datasheet. This tape-and-reel format supports automated pick-and-place assembly and is standard for high-volume production of miniature discrete components like the BZX584B3V3 RSG.
