Product details
Overview
BZB84-B6V8,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, providing precise 6.66 V to 6.94 V nominal regulation per diode at IZ = 5 mA, with ±2 % tolerance, 80 Ω differential resistance, and AEC-Q101 qualification for automotive voltage clamping and reference applications.
For engineers reviewing the BZB84-B6V8,215 datasheet, BZB84-B6V8,215 pinout, BZB84-B6V8,215 application, or BZB84-B6V8,215 equivalent, this device supports dual-channel overvoltage protection, low-temperature-coefficient biasing (1.2 mV/K), and high-surge resilience (40 W non-repetitive peak reverse power) in space-constrained SMT designs.
Technical Context
This dual Zener operates in common-anode configuration: pins 1 and 2 serve as independent cathodes, while pin 3 is the shared anode-enabling bidirectional clamping or dual-voltage referencing from a single footprint. Each diode is rated for 300 mW total power dissipation at Tamb ≤ 25 °C.
It delivers stable regulation across −55 °C to +150 °C ambient, with thermal resistance from junction to ambient of 417 K/W (free air) and junction-to-solder-point of 100 K/W-critical for reliability in under-hood automotive modules and industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 6.66 V to 6.94 V at IZ = 5 mA - defines tight regulation window for precision 6.8 V reference or clamp |
| Tolerance | ±2 % - enables high-accuracy voltage setting without external trimming |
| Differential Resistance (rdif) | 80 Ω max at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W (tp = 100 µs square wave) - supports transient surge suppression in CAN/LIN bus interfaces |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - allows low-loss forward conduction when used in bidirectional ESD paths |
| Reverse Current (IR) | ≤15 µA at VR = 4 V - guarantees low leakage in standby power rails |
| Temperature Coefficient (SZ) | +1.2 mV/K at IZ = 5 mA - provides near-zero drift compensation in temperature-sensitive references |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, small-outline transistor outline with 1.3 mm × 2.9 mm body, 0.95 mm height, and gull-wing leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides regulated Zener breakdown path for first channel; connects to protected node or reference point |
| 2 | Cathode (Diode 2) | Independent second Zener cathode-enables dual-rail clamping (e.g., VCC and VIO) or complementary biasing |
| 3 | Common Anode | Shared anode node tied to ground or negative rail; establishes common reference for both Zeners |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Reduces PCB area by 50 % vs. two discrete SOT23 Zeners; simplifies layout for symmetric voltage protection |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD (HBM ≥ 8 kV) |
| ±2 % Zener tolerance (B-series) | Eliminates post-assembly calibration in safety-critical sensor supply rails and MCU reset circuits |
| Low 80 Ω dynamic impedance | Maintains regulation stability under fast load transients (e.g., microcontroller wake-up current spikes) |
| 150 °C maximum junction temperature | Supports operation in engine control units (ECUs) and powertrain modules without derating at full power |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5235BS-7-F | Single Zener (6.8 V, ±5 %), SOT363 package, 200 mW Ptot, no AEC-Q101 rating | Lacks dual-channel capability and automotive qualification; suitable only for non-safety consumer applications | Select only if dual cathode functionality is unnecessary and cost is primary constraint |
| BZX84-B6V8,215 | Single Zener (6.8 V, ±2 %), SOT23 package, identical voltage spec but no second cathode | Cannot perform simultaneous dual-rail clamping; requires two devices for same function as BZB84-B6V8 | Choose when board space permits discrete placement and common-anode topology is not required |
Compared with MMBZ5235BS-7-F and BZX84-B6V8,215, the BZB84-B6V8,215 uniquely integrates two tightly matched ±2 % Zeners in one AEC-Q101-qualified SOT23, reducing component count by 50 % and enabling compact, automotive-compliant dual-voltage protection without sacrificing precision or surge resilience.

FAQ
What is the maximum continuous power dissipation for BZB84-B6V8,215?
The BZB84-B6V8,215 has a total power dissipation limit of 300 mW at ambient temperatures ≤25 °C, derating linearly above that point with a thermal resistance of 417 K/W. This value applies to the entire dual-diode package-not per diode-and assumes mounting on FR4 PCB with single-sided copper.
Can BZB84-B6V8,215 be used for bidirectional ESD protection?
Yes-its dual common-anode structure allows pins 1 and 2 to clamp positive transients to ground (pin 3), while forward conduction (VF ≤0.9 V at 10 mA) handles negative excursions. It meets IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) when combined with appropriate series impedance.
How does the temperature coefficient affect regulation accuracy over temperature?
At +1.2 mV/K, the BZB84-B6V8,215 exhibits near-zero drift around its 6.8 V nominal point-resulting in only ~±12 mV shift over a 100 °C range (−40 °C to +60 °C). This enables stable reference performance without external compensation in automotive cabin modules.
Is the SOT23 footprint compatible with automated optical inspection (AOI)?
Yes-the SOT23 outline (TO-236AB) has standardized gull-wing lead geometry with 0.95 mm pitch and defined solder land patterns (per Nexperia's sot023_fr and sot023_fw footprints), ensuring reliable AOI detection of solder joint quality, tombstoning, and coplanarity in high-volume SMT lines.
