Product details
Overview
BZX384-A6V2X from Nexperia is a ±1 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, providing precise 6.2 V nominal breakdown voltage at 5 mA test current, 150 Ω typical differential resistance, and ≤10 μA reverse leakage at 4.96 V. It delivers stable reference voltage for low-power analog circuits, power supply feedback paths, and overvoltage protection in consumer and industrial PCBs.
For engineers reviewing the BZX384-A6V2X datasheet, BZX384-A6V2X pinout, BZX384-A6V2X application, or BZX384-A6V2X equivalent, key selection criteria include its ±1 % voltage tolerance, 300 mW total power dissipation at 25 °C ambient, 150 °C maximum junction temperature, and cathode-anode polarity marking on the SOD323 body.
Technical Context
This discrete Zener diode operates in reverse-bias breakdown mode to maintain a stable DC reference voltage across its terminals. Its regulation performance is defined at IZ = 5 mA with 6.13 V minimum and 6.27 V maximum breakdown voltage, and it exhibits a positive temperature coefficient of +0.4 mV/K at that current.
The device supports transient surge handling up to 40 W non-repetitive peak reverse power (100 μs pulse), while maintaining thermal resistance of 415 K/W junction-to-ambient in free air and 110 K/W junction-to-solder-point-critical for compact PCB layouts with limited copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 6.13 V to 6.27 V at IZ = 5 mA - ensures tight 6.2 V regulation for precision feedback loops |
| Tolerance | ±1 % - enables high-accuracy voltage references without post-production trimming |
| Differential Resistance (rdif) | 150 Ω max at IZ = 5 mA - limits output impedance drift under load variation |
| Reverse Leakage (IR) | ≤10 μA at VR = 4.96 V - minimizes quiescent current in battery-powered circuits |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - defines continuous DC power limit on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 μs - supports ESD and surge clamping in transient protection networks |
| Junction Temperature (Tj) | −65 °C to +150 °C - allows operation in extended industrial environments |
Pinout & Package

Key Features

Applications
| Power Supply Feedback | Overvoltage Protection |
|---|---|
|
Use Scenario: Regulating output voltage of isolated flyback or buck converter via optocoupler feedback loop. IC Role / Device Role / Timing Role: Provides stable 6.2 V reference to TL431-like shunt regulator input, setting precise output setpoint. Use Value: ±1 % VZ tolerance directly translates to <±1 % output voltage accuracy without calibration. |
Use Scenario: Clamping transient spikes on 5 V logic rail caused by inductive switching or ESD events. IC Role / Device Role / Timing Role: Acts as passive crowbar element, conducting above 6.2 V to divert surge current away from downstream ICs. Use Value: 40 W non-repetitive peak power rating absorbs 100 μs surges up to 6.2 V × 6.45 A without failure. |
| Reference Voltage Source | Signal Level Shifting |
|
Use Scenario: Generating accurate bias voltage for op-amp comparators or ADC reference buffers in sensor interfaces. IC Role / Device Role / Timing Role: Supplies low-noise, temperature-stable 6.2 V reference to precision analog circuitry. Use Value: +0.4 mV/K temperature coefficient minimizes drift across −40 °C to +85 °C ambient range. |
Use Scenario: Translating 3.3 V microcontroller GPIO signals to 5 V logic levels in mixed-voltage systems. IC Role / Device Role / Timing Role: Functions as simple level translator using forward-biased diode drop (~0.9 V at 10 mA). Use Value: 0.9 V forward voltage at 10 mA enables predictable 2.4 V logic-high threshold on 5 V side. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5234BS | 6.2 V ±5 % tolerance, SOD-323 package, 200 mW Ptot | Lower accuracy and power rating; suitable only where cost outweighs precision | Select when ±5 % tolerance and reduced surge margin are acceptable for basic clamping |
| Vishay BZX384-C6V2 | 6.2 V ±5 % tolerance, same SOD323 package, identical 300 mW Ptot | Higher reverse leakage (≤50 μA at 4.96 V) and wider VZ spread reduce reference stability | Choose only if tighter tolerance is unnecessary and legacy BOM compatibility is required |
Compared with BZX384-A6V2X, MMBZ5234BS trades ±1 % accuracy and 40 W surge capability for lower unit cost, while BZX384-C6V2 retains mechanical compatibility but sacrifices regulation precision and leakage performance-making the A-grade version optimal for feedback-critical and transient-sensitive designs.

FAQ
What is the maximum continuous reverse current this diode can handle?
The BZX384-A6V2X has no specified maximum continuous reverse current; its safe operating limit is defined by power dissipation. At 25 °C ambient on standard FR4 PCB, it sustains ≤300 mW, corresponding to ~48 mA at 6.2 V. Derating is required above 25 °C per the 415 K/W thermal resistance.
Can this Zener be used in series to achieve higher reference voltages?
Yes-multiple BZX384-A6V2X diodes may be stacked anode-to-cathode to sum breakdown voltages. However, mismatched tolerances (±1 % each) accumulate, and thermal coupling between devices affects overall stability; parallel use is not recommended due to current-sharing imbalance.
How does the 150 °C maximum junction temperature impact PCB layout?
A 150 °C Tj rating permits operation in high-temperature zones, but requires thermal design consideration: keep traces short, avoid nearby heat sources, and ensure ≥1 mm clearance from adjacent components to maintain Rth(j-a) ≤415 K/W in free air per datasheet test conditions.
Is the cathode marking visible under standard optical inspection?
Yes-the cathode is indicated by a distinct white or light-colored bar on the SOD323 package body, positioned adjacent to pin 1. This marking is laser-etched or molded and remains clearly identifiable during automated optical inspection (AOI) and manual visual verification.
