Product details
Overview
BZX584B3V6 RSG from Taiwan Semiconductor is a surface-mount Zener diode with nominal zener voltage 3.6 V, ±2% tolerance, 150 mW power dissipation, and SOD-523F package. It provides precise voltage regulation in low-power signal conditioning and biasing circuits, such as reference generation for ADCs or overvoltage clamping in sensor interfaces.
For engineers reviewing the BZX584B3V6 RSG datasheet, BZX584B3V6 RSG pinout, BZX584B3V6 RSG application, or BZX584B3V6 RSG equivalent, key selection criteria include zener voltage accuracy (±2%), low leakage current (≤5 µA at 1.0 V), temperature coefficient (−3.5 mV/°C), and thermal resistance (833 °C/W) in ultra-compact SOD-523F packaging.
Technical Context
This device operates as a single-die, cathode-banded Zener diode optimized for stable reverse-breakdown regulation at 3.6 V under 5 mA test current. Its 90 Ω dynamic impedance at IZT and 600 Ω at IZK supports consistent regulation across load variations in low-current analog rails.
The SOD-523F package enables high-density PCB layouts with moisture sensitivity level 1 compliance and JESD201 Class 1A whisker resistance. Junction temperature range spans −55°C to +150°C, supporting operation in industrial ambient environments without derating below 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.53–3.67 V at 5 mA - ensures tight 3.6 V reference with ±2% tolerance for precision biasing |
| Power Dissipation (PD) | 150 mW - limits continuous regulation current to ~41 mA at 3.6 V in still air |
| Zener Impedance (ZZT) | 90 Ω at 5 mA - maintains voltage stability under small-signal load transients |
| Leakage Current (IR) | ≤5 µA at 1.0 V - minimizes parasitic current draw in high-impedance reference nodes |
| Temperature Coefficient | −3.5 mV/°C - predicts predictable downward drift of VZ with rising junction temperature |
| Junction-to-Ambient RθJA | 833 °C/W - requires careful thermal layout for sustained power operation above 25°C ambient |
Pinout & Package
Package: SOD-523F - ultra-small plastic surface-mount case (1.2 × 0.8 × 0.6 mm), matte tin-plated terminals, cathode indicated by band, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node during regulation; defines polarity for reverse-bias operation |
| Cathode | Zener breakdown terminal / voltage reference output | Connected to regulated node; supplies stable 3.6 V when reverse-biased above breakdown threshold |
Key Features
| Feature | Design Value |
|---|---|
| ±2% zener voltage tolerance | Enables direct use in 3.3 V system references without trimming or calibration |
| SOD-523F footprint | Reduces board area by >50% vs. SOD-323, supporting miniaturized wearables and IoT sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | 3.6 V nominal, ±5% tolerance, 200 mW PD, SOD-323 package | Looser voltage tolerance; higher power rating but larger footprint | Select when board space permits and tighter VZ tolerance is not required |
| BZX384-B3V6,115 | 3.6 V nominal, ±2% tolerance, 300 mW PD, SOD-323 package | Same VZ spec but double power rating and larger package | Select when higher surge energy handling is needed and SOD-523F size constraint is relaxed |
Compared with MMBZ5226BS-7-F and BZX384-B3V6,115, the BZX584B3V6 RSG delivers identical ±2% voltage accuracy in the smallest available footprint (SOD-523F), making it optimal for space-constrained, low-power regulation where thermal budget is managed via layout rather than higher PD.

FAQ
What is the exact zener voltage range and test condition for BZX584B3V6 RSG?
The BZX584B3V6 RSG has a guaranteed zener voltage range of 3.53 V to 3.67 V, measured at a test current (IZT) of 5 mA and ambient temperature of 25°C. This ±2% tolerance is specified per the Taiwan Semiconductor datasheet Version D2007 and applies strictly under those conditions.
Does BZX584B3V6 RSG have a defined polarity marking, and how is it identified?
Yes, BZX584B3V6 RSG uses a cathode band to indicate polarity - the banded end is the cathode terminal. This marking is visible on the SOD-523F package body and must be aligned with the higher-potential node during reverse-bias operation to achieve proper zener regulation.
What is the maximum allowable junction temperature for continuous operation of BZX584B3V6 RSG?
The BZX584B3V6 RSG has a maximum junction temperature (TJ) of +150°C, with an operational range from −55°C to +150°C. Derating begins above 25°C ambient, governed by its 833 °C/W junction-to-ambient thermal resistance - sustained 150 mW dissipation requires careful PCB copper area design.
Is BZX584B3V6 RSG compliant with lead-free and halogen-free manufacturing standards?
Yes, BZX584B3V6 RSG is RoHS compliant and halogen-free per IEC 61249-2-21. Its matte tin-plated terminals meet J-STD-002 solderability requirements, and the molding compound satisfies UL 94V-0 flammability rating - all confirmed in the official Taiwan Semiconductor documentation.
Can BZX584B3V6 RSG replace older through-hole Zeners like 1N4728A in new designs?
No - BZX584B3V6 RSG is a surface-mount SOD-523F device and not a drop-in replacement for through-hole parts like 1N4728A. While both regulate near 3.6 V, differences in package, thermal behavior, and mounting require PCB redesign. Use only where SMD layout and thermal constraints are fully evaluated for BZX584B3V6 RSG.
