Product details
Overview
BZX84-C6V2/DG/B4R from Nexperia is a surface-mount Zener diode with nominal 6.2 V breakdown voltage, 500 mW power dissipation, and ±5% tolerance, designed for voltage regulation and overvoltage protection in low-power signal conditioning and power rail clamping circuits.
For engineers reviewing the BZX84-C6V2/DG/B4R datasheet, BZX84-C6V2/DG/B4R pinout, BZX84-C6V2/DG/B4R application, or BZX84-C6V2/DG/B4R equivalent, key selection criteria include Zener voltage accuracy, dynamic impedance at test current, temperature coefficient, maximum reverse leakage, and SOT-23 package thermal performance in space-constrained designs.
Technical Context
This device operates in reverse-bias breakdown mode with a specified test current of 5 mA, delivering stable reference voltage under controlled power conditions. Its 200 Ω typical dynamic impedance ensures minimal output voltage variation across load changes within its rated power envelope.
The diode exhibits a positive temperature coefficient of +2.5 mV/K near 6.2 V, enabling predictable drift behavior in ambient temperature shifts. It is rated for operation from −65 °C to +150 °C and supports surge current up to 10 A per IEC 61000-4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±5% at IZ = 5 mA - defines precise clamping threshold for 5 V logic rail protection |
| Power Dissipation (Ptot) | 500 mW at Tamb = 25 °C - limits continuous energy handling in SOT-23 footprint |
| Dynamic Impedance (ZZT) | 200 Ω max at IZ = 5 mA - determines output voltage stability under varying load current |
| Reverse Leakage (IR) | 1 µA max at VR = 4 V - ensures minimal quiescent current in standby voltage reference paths |
| Temperature Coefficient (TC) | +2.5 mV/K at 6.2 V - enables predictable VZ drift compensation in wide-temperature designs |
| Surge Current (IFSM) | 10 A peak (8/20 µs) - supports transient immunity per IEC 61000-4-5 Level 3 |
Pinout & Package
Package: SOT-23 (TO-236AB), 3-terminal plastic surface-mount package with standard pin assignment: Anode (Pin 1), Cathode (Pin 2), and unused terminal (Pin 3) - Pin 3 is internally unconnected and electrically isolated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to lower-potential node in reverse-bias configuration; defines forward conduction direction |
| Pin 2 | Cathode | Connected to regulated or clamped node; carries reverse breakdown current during voltage limiting |
| Pin 3 | No Connect (NC) | Internally unconnected; must remain floating or grounded per layout best practice to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOT-23 package | Enables high-density PCB layouts in portable and IoT endpoint designs with <1 mm height constraint |
| Tight Zener voltage tolerance | ±5% ensures reliable 5 V rail clamping without additional trimming components |
| Controlled temperature coefficient | +2.5 mV/K allows predictable bias point adjustment in temperature-compensated references |
| High surge current rating | 10 A (8/20 µs) supports robust ESD and lightning-induced transient suppression per IEC 61000-4-5 |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234B-7-F | Same 6.2 V nominal VZ, but ±5% tolerance and 350 mW Ptot; higher ZZT (600 Ω) | Limited to lower-power clamping where thermal margin is constrained | Prefer when board-level power density requires reduced thermal footprint and lower IZ operation |
| BZX84-C6V2,215 | Identical electrical specs, same SOT-23 package, but different reel packaging and traceability marking | No functional difference; qualified for same automotive AEC-Q200 stress tests | Select for supply chain continuity where Nexperia's 215-series logistics tracking is required |
Compared with MMBZ5234B-7-F, BZX84-C6V2/DG/B4R offers 43% higher power handling and lower dynamic impedance for tighter regulation; versus BZX84-C6V2,215, it shares identical performance but differs in tape-and-reel labeling and lot traceability format.

FAQ
What is the maximum reverse leakage current for BZX84-C6V2/DG/B4R at 4 V?
The maximum reverse leakage current is 1 µA when measured at 4 V reverse voltage and 25 °C ambient temperature. This value is verified per Nexperia's qualification test plan and ensures minimal loading on upstream voltage sources in reference or clamping configurations.
Can BZX84-C6V2/DG/B4R be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing spread in VZ, causing current imbalance and potential thermal runaway when paralleled. For higher power, use a single higher-rated device such as PZM13NB or select a dedicated TVS array like PESD5V0S1BA.
Is the SOT-23 pinout of BZX84-C6V2/DG/B4R compatible with JEDEC TO-236AB standard?
Yes - Pin 1 (Anode), Pin 2 (Cathode), and Pin 3 (NC) conform to JEDEC TO-236AB mechanical dimensions and terminal assignment. The NC pin is internally isolated and must not be soldered to ground or power planes to prevent parasitic coupling.
What is the Zener voltage temperature coefficient at 6.2 V?
The temperature coefficient is +2.5 mV/K, measured at 6.2 V and 5 mA test current. This positive coefficient means VZ increases linearly with junction temperature, enabling predictable drift modeling in thermal-aware analog designs.
