Product details
Overview
BZX84W-C6V2X from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT323 (SC-70) package, rated for 6.2 V nominal Zener voltage at 5 mA, 150 Ω differential resistance, and 2.3 mV/K temperature coefficient. It delivers stable reference voltage in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the BZX84W-C6V2X datasheet, BZX84W-C6V2X pinout, BZX84W-C6V2X application, or BZX84W-C6V2X equivalent, key selection criteria include Zener voltage tolerance, thermal coefficient, junction-to-ambient thermal resistance, reverse leakage at 4 V, and SOT323 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain a precise DC reference voltage under varying load and temperature conditions. Its 6.2 V nominal Zener voltage is specified at IZ = 5 mA with ±5 % tolerance and exhibits a positive temperature coefficient of +2.3 mV/K, indicating voltage increases with rising junction temperature.
The device features low dynamic impedance (150 Ω at 5 mA), enabling effective regulation in low-current applications. With 275 mW total power dissipation on FR4 PCB and 455 K/W junction-to-ambient thermal resistance, it supports operation up to 150 °C junction temperature in compact surface-mount designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal at IZ = 5 mA; ±5 % tolerance ensures predictable clamping within 5.8–6.6 V range |
| Differential Resistance (rdif) | 150 Ω at IZ = 5 mA; defines regulation stiffness-lower values yield tighter voltage control under current variation |
| Temperature Coefficient (SZ) | +2.3 mV/K at IZ = 5 mA; quantifies voltage drift per degree rise-critical for temperature-stable references |
| Reverse Leakage (IR) | 3 µA max at VR = 4 V; determines quiescent current draw in standby regulation or sensing paths |
| Total Power Dissipation (Ptot) | 275 mW on FR4 PCB; sets maximum continuous power handling without heatsinking in standard layout |
| Junction-to-Ambient Rth(j-a) | 455 K/W; indicates thermal performance-higher value implies greater self-heating at given power |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA; relevant for polarity-sensitive protection or dual-use rectifier applications |
Pinout & Package
Package: SOT323 (SC-70), leadless surface-mount plastic package with 3 terminals; dimensions per IEC JEDEC outline (D = 2.2 mm, E = 1.35 mm, A1 max = 0.1 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential side in reverse-bias Zener operation; forward conduction path when used as rectifier |
| 2 | Not Connected (n.c.) | Internally unconnected terminal-must remain floating; no routing or soldering required |
| 3 | Cathode (K) | Connected to higher-potential side in Zener mode; defines polarity for voltage reference or clamp direction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective precision where tight regulation suffices without ±2 % premium |
| Low 150 Ω dynamic impedance | Maintains stable output under ±1 mA load shifts-suitable for sensor biasing and op-amp reference networks |
| Positive +2.3 mV/K tempco | Compensates negative tempcos in other circuit elements (e.g., BJTs), supporting compensated reference designs |
| 275 mW power rating on FR4 | Supports direct integration into 3.3 V/5 V rail monitoring without external resistors or derating |
| SOT323 footprint | Enables high-density placement in space-constrained IoT nodes, wearables, and portable power management |
Applications
| Power Supply Feedback | Overvoltage Clamp |
|---|---|
|
Use Scenario: Regulating output voltage in low-power linear regulators or switching converter feedback dividers. IC Role / Device Role / Timing Role: Provides stable 6.2 V reference point for error amplifier comparison. Use Value: Enables ±1 % output accuracy with minimal external components due to tight VZ tolerance and low rdif. |
Use Scenario: Protecting microcontroller I/O pins from transient overvoltage events. IC Role / Device Role / Timing Role: Acts as shunt clamp, conducting excess current above 6.2 V to ground. Use Value: Limits voltage excursion to ≤6.6 V (max VZ) while drawing only 3 µA leakage below clamp threshold. |
| Reference Voltage Source | High-Frequency Signal Conditioning |
|
Use Scenario: Generating fixed bias for analog front-end amplifiers or ADC reference buffers. IC Role / Device Role / Timing Role: Supplies low-noise, temperature-compensated DC reference voltage. Use Value: +2.3 mV/K tempco allows predictable tracking with downstream components, reducing calibration burden. |
Use Scenario: AC-coupled clipping in RF detector or envelope follower circuits. IC Role / Device Role / Timing Role: Performs fast reverse-breakdown limiting on signal peaks. Use Value: Low 6 pF capacitance at 0 V bias minimizes signal distortion up to 100 MHz bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84W-B6V2 | ±2 % tolerance (5.98–6.32 V vs. 5.8–6.6 V); identical package, pinout, and thermal specs | Higher precision needed for metrology-grade references or closed-loop feedback requiring <±1 % error | Select when tighter VZ tolerance justifies cost premium; otherwise BZX84W-C6V2X offers optimal balance |
| MMBZ5234BS | Same 6.2 V nominal, ±5 %, but SOT363 package (dual diode); 200 mW Ptot; 250 Ω rdif | Requires dual-diode configuration or board redesign; lower power and higher impedance reduce regulation fidelity | Only consider if dual-Zener functionality or existing SOT363 footprint mandates reuse-otherwise inferior regulation performance |
Compared with BZX84W-B6V2, the C6V2X trades 0.32 V wider VZ spread for lower cost and sufficient stability in non-critical regulation; versus MMBZ5234BS, it delivers 35 % lower dynamic impedance and 37.5 % higher power handling in the same board area.

FAQ
What is the maximum reverse current at 4 V for BZX84W-C6V2X?
The maximum reverse leakage current is 3 µA at VR = 4 V and Tj = 25 °C, as specified in Table 7 of the datasheet. This low leakage ensures minimal parasitic loading in high-impedance reference or sensing nodes, preserving accuracy in battery-powered or ultra-low-power designs.
Can BZX84W-C6V2X be used in place of a 6.2 V Zener with ±2 % tolerance?
Yes, but with reduced voltage accuracy: BZX84W-C6V2X has ±5 % tolerance (5.8–6.6 V), versus ±2 % (5.98–6.32 V) for B-series parts. Use only where system-level tolerance budgets accommodate the wider 0.8 V span-e.g., non-critical clamping or coarse feedback-not precision references.
What is the thermal resistance from junction to ambient for this diode?
The thermal resistance is 455 K/W under standard mounting conditions (FR4 PCB, single-sided copper, tin-plated, standard footprint). This value means a 275 mW dissipation causes ~125 °C junction-to-ambient rise, requiring ambient derating above 25 °C to stay within the 150 °C absolute maximum junction temperature.
Is Pin 2 internally connected in the SOT323 package?
No-Pin 2 is explicitly designated "not connected" (n.c.) in Table 2 of the datasheet. It is electrically isolated from the die and must remain unconnected in layout and assembly; soldering or routing to this pin risks mechanical stress or unintended coupling without functional benefit.
