Product details
Overview
BZB84-B2V4,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 2.4 V nominal Zener voltage (±2 % tolerance), 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves as a precision voltage reference or overvoltage clamp in low-power automotive and industrial power rails.
For engineers reviewing the BZB84-B2V4,215 datasheet, BZB84-B2V4,215 pinout, BZB84-B2V4,215 application, or BZB84-B2V4,215 equivalent, this device is selected for dual-rail clamping, ESD-protected I/O regulation, and AEC-Q101-compliant voltage stabilization where space-constrained SMT design and tight voltage tolerance are critical.
Technical Context
This dual-Zener diode integrates two identical 2.4 V Zener elements sharing a common anode (Pin 3), enabling symmetrical bidirectional clamping or independent regulation of two signals referenced to the same node. Its ±2 % tolerance and low 600 Ω differential resistance at 5 mA support stable regulation under moderate load variation.
Designed for automotive-grade reliability, it meets AEC-Q101 stress qualification and operates across −55 °C to +150 °C ambient, with thermal resistance from junction to ambient of 417 K/W on FR4 PCB - confirming suitability for thermally constrained embedded control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.35 V to 2.45 V at IZ = 5 mA - ensures precise 2.4 V reference with ±2 % accuracy for feedback loops or threshold detection |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling before thermal derating begins |
| Differential Resistance (rdif) | 600 Ω max at IZ = 5 mA - indicates regulation stiffness; lower values improve line/load regulation performance |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - confirms low-loss conduction when used as a forward-biased clamp or protection diode |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W at tp = 100 µs - supports transient surge suppression (e.g., ISO 7637-2 pulses) without failure |
| Junction Temperature (Tj) | 150 °C max - sets upper thermal limit for reliable operation in engine bay or power supply environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test standard, enabling use in ADAS sensors and body control modules |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small-outline transistor outline with gull-wing leads; footprint compatible with standard reflow and wave soldering per Nexperia's sot023_fr/sot023_fw guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides Zener breakdown path for first diode; connects to regulated node or signal line requiring clamping |
| 2 | Cathode (Diode 2) | Independent cathode for second Zener element; enables dual-rail or complementary clamping topology |
| 3 | Common Anode | Shared anode terminal; ties both diodes to ground or common reference, defining bidirectional clamping behavior |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Enables compact bidirectional voltage clamping (e.g., ±2.4 V around ground) without external component duplication |
| ±2 % Zener voltage tolerance | Reduces calibration overhead in precision analog circuits and improves consistency across production batches |
| AEC-Q101 qualification | Validates robustness against temperature cycling, humidity, and mechanical stress required for automotive under-hood applications |
| 40 W non-repetitive peak power rating | Withstands short-duration transients (e.g., load dump, ESD) without degradation, extending system-level surge immunity |
| Low 0.9 V forward voltage | Minimizes conduction loss during forward-biased operation, improving efficiency in active clamp or polarity protection roles |
Applications
| Automotive Sensor Interface | Industrial I/O Protection |
|---|---|
Use Scenario: Protecting analog inputs of engine control unit (ECU) ADC channels from induced transients on 5 V sensor lines. IC Role / Device Role / Timing Role: Dual-Zener clamps signal-to-ground and signal-to-VCC, limiting excursion to ±2.4 V relative to common reference. Use Value: Prevents ADC saturation and latch-up while maintaining signal fidelity within 2.4 V compliance window defined by AEC-Q100 Class 0 thresholds. |
Use Scenario: Safeguarding RS-485 transceiver I/O pins against ESD and cable-induced surges in factory automation PLCs. IC Role / Device Role / Timing Role: Acts as bidirectional rail clamp between differential pair and ground, leveraging common-anode symmetry for balanced protection. Use Value: Achieves IEC 61000-4-2 Level 4 (±15 kV air) robustness without adding discrete TVS arrays, reducing BOM count and board area. |
| Low-Power Voltage Reference | USB Port Overvoltage Clamp |
Use Scenario: Generating stable 2.4 V bias for op-amp comparators in battery-powered IoT node voltage monitors. IC Role / Device Role / Timing Role: Provides precision reference via Zener breakdown; low rdif maintains stability under microampere load variations. Use Value: Delivers <±10 mV drift over 0–70 °C ambient, eliminating need for trimming resistors or higher-cost shunt references. |
Use Scenario: Clamping VBUS and D+/D− lines in USB 2.0 host ports against hot-plug overshoot and ESD events. IC Role / Device Role / Timing Role: Common-anode configuration allows single device to clamp all three lines to ground simultaneously during surge events. Use Value: Reduces layout complexity versus three discrete Zeners and meets USB-IF ESD requirements with 40 W pulse capability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZB84-C2V4,215 | ±5 % Zener tolerance vs. ±2 %; otherwise identical electrical specs and package | Lower cost for non-critical regulation where tighter voltage accuracy is unnecessary | Select when budget constraints outweigh need for high-precision reference stability |
| MMBZ5221BS-7-F | Single Zener (2.4 V, ±5 %), SOT23 package; no dual configuration or common-anode topology | Requires two devices for bidirectional clamping; lacks integrated dual-element symmetry | Choose only if discrete placement flexibility is needed and board space permits duplication |
Compared with BZB84-C2V4,215, the BZB84-B2V4,215 offers tighter voltage control essential for feedback-sensitive circuits; versus MMBZ5221BS-7-F, its dual-common-anode structure reduces component count and improves layout symmetry for differential signal protection.

FAQ
What is the maximum continuous reverse current the BZB84-B2V4,215 can sustain at 25 °C?
The device does not specify a maximum continuous reverse current (IZ) directly, but its 300 mW total power dissipation limits IZ to approximately 125 mA at 2.4 V (P = V × I). Operation above this level requires thermal derating per the Rth(j-a) = 417 K/W characteristic and ambient temperature conditions.
Can the BZB84-B2V4,215 be used for bidirectional ESD protection on a single-ended signal line?
Yes - with Pin 3 (common anode) grounded and Pins 1 & 2 connected to the protected signal, it provides symmetrical ±2.4 V clamping. This configuration meets IEC 61000-4-2 Level 4 ESD immunity when combined with appropriate series impedance, leveraging its 40 W non-repetitive peak power rating.
How does the ±2 % tolerance affect regulation accuracy in a 3.3 V LDO feedback network?
When used as a 2.4 V reference in a resistor-divider feedback network for a 3.3 V LDO, ±2 % VZ translates to ±0.048 V error at the reference node, resulting in ±1.5 % output voltage variation. This is acceptable for non-precision applications but insufficient for <1 % output tolerance requirements.
Is the SOT23 package of BZB84-B2V4,215 compatible with standard reflow profiles for lead-free assembly?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOT23 outline (TO-236AB) has documented reflow footprints (sot023_fr) with 0.5 mm pad width and 0.6 mm solder paste stencil openings, supporting peak temperatures up to 260 °C for 10 seconds in Pb-free processes.
