Product details
Overview
BZX84W-C6V2F from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT323 (SC-70) package, providing 6.2 V nominal regulation at 5 mA with 150 Ω differential resistance and +2.3 mV/K temperature coefficient. It delivers stable reference voltage for low-power analog circuits, operates up to 150 °C junction temperature, and supports high-frequency decoupling due to 200 pF capacitance at 1 MHz.
For engineers reviewing the BZX84W-C6V2F datasheet, BZX84W-C6V2F pinout, BZX84W-C6V2F application, or BZX84W-C6V2F equivalent, this page provides verified Zener voltage, thermal resistance (455 K/W), reverse leakage (3 µA at 4 V), forward voltage (≤0.9 V at 10 mA), and SOT323 terminal mapping to support precision biasing, voltage clamping, and reference design validation.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 6.2 V reference across load and supply variations, with tight ±5 % tolerance ensuring predictable regulation in feedback loops and sensing circuits. Its low 150 Ω dynamic impedance minimizes output voltage deviation under changing current conditions.
The +2.3 mV/K positive temperature coefficient counteracts typical semiconductor drift in mid-voltage Zeners, improving thermal stability in ambient ranges from −55 °C to +150 °C. The 275 mW total power dissipation rating assumes FR4 PCB mounting with single-sided copper and standard footprint per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal at IZ = 5 mA; ensures precise voltage reference for analog comparators and ADC references. |
| Tolerance | ±5 % (C-series); guarantees consistent regulation across production batches without post-manufacture trimming. |
| Differential Resistance (rdif) | 150 Ω max at IZ = 5 mA; limits output voltage shift to ≤0.75 V per 5 mA load change. |
| Reverse Leakage (IR) | 3 µA max at VR = 4 V; enables low-quiescent-current bias networks in battery-powered sensors. |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA; allows use as low-drop rectifier or ESD clamp in signal paths. |
| Thermal Resistance (Rth(j-a)) | 455 K/W on FR4 PCB; defines 0.6 °C/mW self-heating rise, critical for thermal derating above 25 °C ambient. |
| Capacitance (Cd) | 200 pF at f = 1 MHz, VR = 0 V; supports RF bypass applications up to ~800 MHz before impedance drops below 1 kΩ. |
Pinout & Package
Package: SOT323 (SC-70), leadless surface-mount plastic package with 3 terminals, 1.3 mm × 1.8 mm footprint, 0.65 mm pitch, and 0.25 mm maximum A1 height per JEDEC MO-203-AB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node in reverse-bias configuration; must be held ≤6.2 V below cathode for regulation. |
| 2 | Not Connected (n.c.) | Internally unconnected; no electrical function-must remain floating or grounded per layout best practice to avoid parasitic coupling. |
| 3 | Cathode (K) | Connected to higher-potential node; supplies regulated 6.2 V output when reverse-biased with current-limiting resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Zener voltage range | 2.4 V to 75 V in E24 steps-enables single-family selection for diverse rail voltages from logic-level to industrial supplies. |
| Two tolerance options | ±2 % (B-series) and ±5 % (C-series)-supports cost-sensitive designs where tighter tolerance isn't required for functional margin. |
| High-frequency suitability | 200 pF capacitance and low-inductance SOT323 package-minimizes impedance rise up to UHF bands for RF decoupling and noise suppression. |
| Robust thermal performance | 150 °C max junction temperature and −55 °C min ambient rating-enables operation in automotive under-hood and industrial control environments. |
| Standardized marking | P6% code per Table 4-allows rapid visual identification of 6.2 V ±5 % variant on assembled PCBs without test equipment. |
Applications
| Power Supply Reference | Sensor Bias Network |
|---|---|
Use Scenario: Providing stable 6.2 V reference for op-amp-based current-sense amplifiers in DC-DC converter feedback loops. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, absorbing excess current to hold output node at precise 6.2 V despite input ripple. Use Value: Enables <1 % output voltage regulation error over line/load/temperature with no active components, reducing BOM count and failure modes. |
Use Scenario: Biasing thermistor or RTD bridges in industrial temperature transmitters operating from 12 V rails. IC Role / Device Role / Timing Role: Supplies fixed 6.2 V excitation voltage to resistive sensor elements, isolating measurement accuracy from supply variation. Use Value: Delivers <0.5 % reference stability over −40 °C to +85 °C ambient, meeting Class A sensor accuracy requirements per IEC 60751. |
| Overvoltage Clamp | Signal-Level Shifter |
Use Scenario: Protecting microcontroller GPIO pins from transient surges on 5 V I²C bus lines in factory automation systems. IC Role / Device Role / Timing Role: Zener conducts above 6.2 V to divert surge energy to ground, clamping peak voltage to safe levels. Use Value: Limits transient overshoot to ≤6.8 V (including dynamic impedance drop), preventing latch-up in 5 V tolerant inputs per JEDEC JESD78. |
Use Scenario: Translating 3.3 V logic signals to 5 V domains in mixed-voltage FPGA interfaces using passive level-shifting topology. IC Role / Device Role / Timing Role: Functions as bidirectional clamp between rails, enabling safe voltage translation without direction control logic. Use Value: Supports >10 MHz signal integrity with <200 pF loading and sub-nanosecond response, eliminating need for active translators in low-speed control paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5234BS | 6.2 V ±5 %, SOT-323, 200 mW Ptot, 170 Ω rdif, −2.5 mV/K tempco | Negative tempco increases drift in warm environments; lower power rating requires stricter thermal layout. | Select when negative tempco aligns with system drift compensation strategy and board space permits thermal relief. |
| Vishay BZX84-C6V2 | 6.2 V ±5 %, SOT-23, 350 mW Ptot, 150 Ω rdif, +2.5 mV/K tempco, same marking P6% | Larger SOT-23 footprint eases hand-soldering but occupies 2.5× more PCB area than SOT323. | Prefer for prototyping or high-reliability assemblies where thermal margin outweighs miniaturization needs. |
Compared with MMBZ5234BS, BZX84W-C6V2F offers superior thermal stability (+2.3 vs −2.5 mV/K) and identical dynamic impedance, while Vishay's BZX84-C6V2 trades SOT323 miniaturization for higher power handling and broader industry adoption-making it suitable for volume production where footprint flexibility exists.

FAQ
What is the maximum continuous reverse current for BZX84W-C6V2F?
The device supports up to 200 mA forward current per Absolute Maximum Ratings, but its Zener operation relies on controlled reverse current. At 6.2 V regulation, the maximum recommended continuous reverse current is 44 mA-calculated from 275 mW total power dissipation divided by 6.2 V-ensuring junction temperature stays within 150 °C limit on standard FR4 PCB.
How does the +2.3 mV/K temperature coefficient affect circuit accuracy?
This positive coefficient means output voltage increases by 2.3 mV per °C rise in junction temperature. Over a 100 °C range (−25 °C to +75 °C), regulation shifts by ±230 mV-approximately ±3.7 % of 6.2 V. For high-accuracy applications, thermal management or compensation techniques are required to maintain sub-1 % stability.
Can BZX84W-C6V2F replace through-hole Zeners like 1N4735A?
Yes, electrically-both provide 6.2 V ±5 % regulation-but BZX84W-C6V2F uses SOT323 packaging versus DO-35 for 1N4735A. Key differences include lower power rating (275 mW vs 1 W), smaller size, and higher thermal resistance (455 K/W vs ~100 K/W). Replacement requires verifying PCB layout, thermal relief, and surge capability meet system requirements.
Is BZX84W-C6V2F qualified for automotive applications?
No. Per Revision History Section 13, this part is non-automotive qualified. Nexperia explicitly states in the data sheet that BZX84W_SER v.2 removed automotive qualification; automotive-grade alternatives (e.g., BZX84W-Q series) must be selected for AEC-Q200 compliance and extended temperature validation.
