Product details
Overview
BZB84-B3V0,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and transient suppression in compact DC power rails. It delivers nominal 3.0 V Zener voltage (±2 % tolerance), ≤600 Ω differential resistance at 5 mA, and supports ≤40 W non-repetitive peak reverse power dissipation - used in automotive body control modules for ECU reference voltage stabilization.
For engineers reviewing the BZB84-B3V0,215 datasheet, BZB84-B3V0,215 pinout, BZB84-B3V0,215 application, or BZB84-B3V0,215 equivalent, key selection criteria include dual-Zener common-anode topology, AEC-Q101 qualification, 300 mW total power dissipation, and 2.94–3.06 V working voltage range under IZ = 5 mA.
Technical Context
This dual-Zener device integrates two identical 3.0 V Zener elements sharing a common anode (Pin 3), enabling bidirectional clamping or dual-rail regulation from a single footprint. Its ±2 % voltage tolerance and low 10 µA reverse current at 2.4 V support stable reference generation in low-power sensor interfaces.
The SOT23 package provides thermal resistance of 417 K/W (junction-to-ambient) and supports reflow/wave soldering per JEDEC standards. AEC-Q101 qualification confirms suitability for automotive ambient temperatures from −55 °C to +150 °C and mechanical shock/vibration requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.94 V to 3.06 V at IZ = 5 mA - ensures tight regulation window for 3.3 V rail monitoring |
| Differential Resistance rdif | ≤600 Ω - maintains low dynamic impedance for stable reference under load variation |
| Reverse Current IR | ≤10 µA at VR = 2.4 V - minimizes standby leakage in battery-powered systems |
| Total Power Dissipation Ptot | 300 mW at Tamb ≤25 °C - defines continuous thermal limit on standard FR4 PCB |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 µs - enables robust ESD/EMI transient suppression per IEC 61000-4-2 |
| Junction Temperature Tj | 150 °C maximum - allows operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package with 3 leads, 1.9 mm × 1.1 mm body, 0.9 mm height, and gull-wing terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides Zener breakdown path for first diode; connects to regulated node or clamp target |
| 2 | Cathode (Diode 2) | Enables independent clamping of second signal/rail; supports dual-voltage protection |
| 3 | Common Anode | Shared anode connection simplifies PCB routing and reduces component count vs. discrete dual diodes |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Reduces board space by 40 % vs. two separate SOT23 Zeners while enabling symmetrical bidirectional clamping |
| ±2 % Zener voltage tolerance (B-series) | Supports high-accuracy 3.0 V reference without external trimming in ADC bias or LDO feedback paths |
| AEC-Q101 qualification | Validates performance across −55 °C to +150 °C, 1000-cycle temperature cycling, and 1000-hr HTRB for automotive ECUs |
| 40 W non-repetitive peak power | Withstands 8 kV contact ESD (IEC 61000-4-2) without degradation when used with 100 Ω series impedance |
| 300 mW total power rating | Permits continuous operation at 100 mA Zener current in ambient ≤25 °C on standard FR4 with tin-plated copper |
Applications
| Automotive Body Control Unit (BCU) | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZB84-C3V0,215 | ±5 % Zener tolerance (vs. ±2 %); otherwise identical pinout, package, and power ratings | Acceptable where 3.0 V reference accuracy < ±5 % suffices, e.g., non-critical power-good detection | Select for cost-sensitive designs where tighter voltage tolerance is unnecessary |
| MMBZ5222BS-7-F | Single Zener (3.0 V, ±5 %), SOT363 package, 200 mW Ptot, no common-anode dual configuration | Requires two devices for dual-rail clamping; higher board area and assembly cost | Use only if dual common-anode topology is not required and space permits discrete placement |
Compared with BZB84-C3V0,215, the BZB84-B3V0,215 offers tighter regulation critical for precision references; versus MMBZ5222BS-7-F, it delivers integrated dual functionality and higher surge robustness in half the footprint.

FAQ
What is the maximum continuous Zener current for BZB84-B3V0,215 at 25 °C ambient?
The device supports up to 100 mA continuous Zener current at Tamb = 25 °C, derived from its 300 mW total power dissipation rating and 3.0 V nominal Zener voltage (P = V × I → I = 300 mW / 3.0 V). Derating is required above 25 °C per the 417 K/W junction-to-ambient thermal resistance.
Can BZB84-B3V0,215 be used for bidirectional ESD protection on a data line?
Yes - its dual common-anode structure allows one cathode to clamp positive transients and the other to clamp negative transients relative to the shared anode, providing symmetrical ±3.0 V clamping. It meets IEC 61000-4-2 Level 4 (8 kV contact) when paired with appropriate series impedance.
How does the ±2 % tolerance affect stability in a 3.3 V LDO feedback network?
At IZ = 5 mA, the 2.94–3.06 V range introduces ≤0.4 % error in the feedback divider ratio when used to set 3.3 V output. This remains within typical LDO accuracy specs (±1–2 %), making it suitable for cost-optimized designs where external trimming is omitted.
Is the SOT23 footprint compatible with automated optical inspection (AOI) after reflow?
Yes - the SOT23 outline (TO-236AB) has standardized gull-wing lead geometry with 0.95 mm pitch and 0.6 mm solder land width per Nexperia's recommended footprint. This satisfies IPC-A-610 Class 2 AOI detectability requirements for coplanarity and solder joint formation.
