Product details
Overview
BZX84-C6V2/DG/B3,2 from Nexperia is a 6.2 V ±5% Zener diode in SOT23 package, rated for 300 mW power dissipation at TA = 25 °C, with 100 nA maximum reverse leakage at 4 V and 3 Ω typical dynamic impedance at IZ = 5 mA, used for voltage regulation and overvoltage protection in low-power analog sensor interfaces.
For engineers reviewing the BZX84-C6V2/DG/B3,2 datasheet, BZX84-C6V2/DG/B3,2 pinout, BZX84-C6V2/DG/B3,2 application, or BZX84-C6V2/DG/B3,2 equivalent, key selection criteria include Zener voltage tolerance, power derating above 25 °C, thermal resistance RthJA, reverse leakage at operating bias, and dynamic impedance impact on regulation stability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage across varying load currents. Its 6.2 V nominal Zener voltage is specified at test current IZ = 5 mA, with temperature coefficient of +2.5 mV/K and maximum Zener impedance of 30 Ω at IZ = 1 mA.
The SOT23 package provides surface-mount compatibility with RthJA = 375 K/W, requiring thermal design consideration for sustained power operation. Device exhibits soft knee characteristics below 1 mA, limiting use in ultra-low-current precision references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2 V ±5% at IZ = 5 mA - defines regulated output voltage with ±0.31 V tolerance band under standard test condition |
| Power Dissipation Ptot | 300 mW at TA = 25 °C - sets maximum continuous DC power before thermal shutdown; derates linearly above 25 °C |
| Dynamic Impedance ZZ | 3 Ω typical at IZ = 5 mA - determines regulation error sensitivity to load current changes |
| Reverse Leakage IR | 100 nA max at VR = 4 V - limits parasitic current draw in standby or high-impedance bias networks |
| Package | SOT23 - enables automated pick-and-place assembly and occupies 2.9 mm × 1.3 mm PCB area with 0.95 mm height |
| Thermal Resistance RthJA | 375 K/W - dictates junction-to-ambient temperature rise per watt; requires layout-aware copper pour for >150 mW operation |
Pinout & Package
SOT23 package with three terminals: anode (pin 1), cathode (pin 2), and unused pin 3 (internal die attach). Cathode marked by band on package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to lower-potential node; reverse-biased during regulation; must be routed with minimal trace inductance for transient response |
| Pin 2 | Cathode | Marked terminal; connected to regulated voltage rail; carries full Zener current and requires adequate copper width for thermal conduction |
| Pin 3 | Internal Die Attach | Not electrically connected; serves mechanical anchoring only; must not be soldered to signal or power planes |
Key Features
| Feature | Design Value |
|---|---|
| Tight voltage tolerance | ±5% at 5 mA ensures predictable clamping level in 3.3 V and 5 V system rails without post-calibration |
| Low dynamic impedance | 3 Ω typical minimizes output voltage shift under ±10 mA load transients in sensor bias networks |
| Controlled leakage current | ≤100 nA at 4 V prevents measurable error in microamp-level current-sense amplifier feedback paths |
| SOT23 footprint compatibility | Matches industry-standard 3-pin SOT23 land pattern, enabling drop-in replacement across multiple Zener families |
Applications
| Voltage Reference for ADC Biasing | Overvoltage Clamp in RS-485 Receivers |
|---|---|
Use Scenario: Providing stable 6.2 V reference to bias op-amps driving SAR ADC input stages in industrial data acquisition modules. IC Role / Device Role / Timing Role: Zener diode acting as shunt voltage reference with passive filtering to reduce noise coupling into high-resolution analog front-ends. Use Value: ±5% tolerance and 3 Ω impedance ensure <0.5 LSB error contribution at 16-bit resolution when combined with 10 kΩ series resistor. | Use Scenario: Protecting RS-485 receiver inputs against ESD-induced transients exceeding ±15 kV contact discharge per IEC 61000-4-2. IC Role / Device Role / Timing Role: Shunt clamping device placed between differential bus lines and ground to limit common-mode overvoltage during surge events. Use Value: 100 nA leakage avoids loading receiver input impedance (>12 kΩ), preserving signal integrity while clamping peaks above 6.2 V. |

Use Scenario: Stabilizing 6.2 V intermediate rail derived from boost converter in battery-powered environmental sensors. IC Role / Device Role / Timing Role: Passive voltage regulator maintaining constant bias for MEMS pressure transducer excitation circuitry. Use Value: 300 mW rating supports up to 48 mA load current at 25 °C, sufficient for dual-sensor analog signal chains. | Use Scenario: Generating precise 6.2 V threshold for comparator-based level-shifting between 3.3 V MCU GPIO and 5 V peripheral logic. IC Role / Device Role / Timing Role: Zener-defined reference voltage applied to comparator inverting input to set switching point. Use Value: +2.5 mV/K tempco allows predictable 12 mV drift over –40 °C to +85 °C, enabling software compensation in firmware. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2,215 | Same Zener voltage and tolerance, but packaged in SOT23-3 with pin 3 internally unconnected; identical RthJA and ZZ | No functional difference; pin 3 unused in both variants; compatible with same PCB footprint | Select based on distributor stock availability; no electrical or thermal trade-offs |
| MMSZ5234B-7-F | 6.2 V ±5%, but rated for 500 mW in SOD-123; higher power handling and lower RthJA (300 K/W) | Preferred where >300 mW dissipation required or board space permits larger SOD-123 footprint | Choose for higher reliability in thermally constrained environments; requires land pattern change |
Compared with BZX84-C6V2/DG/B3,2, the BZX84-C6V2,215 offers identical performance in the same package, while MMSZ5234B-7-F trades smaller size for higher power capability and improved thermal resistance-critical for sustained operation above 150 mW.

FAQ
What is the maximum reverse current at 4 V for BZX84-C6V2/DG/B3,2?
The maximum reverse leakage current is 100 nA at VR = 4 V and TA = 25 °C, as specified in Nexperia's official datasheet Rev. 10–2022. This value increases with temperature but remains below 1 µA up to 85 °C, making it suitable for low-power bias networks where leakage-induced offset must be minimized.
Can BZX84-C6V2/DG/B3,2 replace BZX84-C6V2,215 in existing designs?
Yes-both share identical electrical specifications, thermal characteristics, and SOT23-3 mechanical dimensions. Pin 3 is unconnected in both versions, and the marking differences (DG/B3,2 vs. 215) reflect internal wafer lot and assembly traceability, not functional variation. No layout or schematic changes are required.
What is the Zener impedance at 1 mA test current?
The maximum dynamic impedance is 30 Ω at IZ = 1 mA, per Nexperia's datasheet. This higher value versus the 3 Ω typical at 5 mA reflects the softer knee region of the Zener curve, meaning regulation accuracy degrades significantly below 2 mA-designs should maintain ≥2 mA operating current for stable performance.
How does temperature affect the Zener voltage of this device?
The BZX84-C6V2/DG/B3,2 has a positive temperature coefficient of +2.5 mV/K, meaning its Zener voltage increases by approximately 2.5 mV per degree Celsius rise in junction temperature. Over the –40 °C to +125 °C range, this results in a total shift of ±425 mV relative to the 25 °C value, requiring compensation in precision reference applications.
