Product details
Overview
BZB84-C5V1,215 from Nexperia is a dual common-anode Zener diode in SOT23 (TO-236AB) package, rated for 5.1 V nominal Zener voltage (±5 % tolerance), 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It operates across −55 °C to +150 °C ambient and is AEC-Q101 qualified for automotive voltage regulation and overvoltage protection.
For engineers reviewing the BZB84-C5V1,215 datasheet, BZB84-C5V1,215 pinout, BZB84-C5V1,215 application, or BZB84-C5V1,215 equivalent, this device serves as a compact, dual-channel precision reference and clamping solution in space-constrained DC power rails, sensor signal conditioning, and ESD-protected I/O interfaces.
Technical Context
This dual Zener diode integrates two independent 5.1 V Zener elements sharing a common anode terminal (Pin 3), enabling bidirectional voltage clamping or dual-rail reference generation from a single footprint. Its differential resistance of 480 Ω at IZ = 5 mA ensures stable regulation under moderate load variation.
The device features a temperature coefficient of −2.7 to +1.2 mV/K at 5 mA, supporting predictable drift behavior in automotive environments. With 300 pF capacitance at 0 V and 1 MHz, it maintains low signal distortion in high-frequency clamp applications without compromising transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.8 V to 5.4 V at IZ = 5 mA - defines precise clamping threshold for 5 V logic and supply rails |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets continuous thermal limit on standard FR4 PCB |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 µs - enables robust surge suppression against ESD or load-dump transients |
| Differential Resistance (rdif) | 480 Ω max at IZ = 5 mA - determines regulation accuracy under varying current demand |
| Reverse Current (IR) | 2 µA max at VR = 3 V - ensures minimal leakage in standby or low-power modes |
| Junction Temperature (Tj) | 150 °C maximum - supports operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, small-outline transistor outline with gull-wing leads; 1.9 mm × 1.3 mm body, 0.95 mm height, standard footprint compatible with 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) | Enables independent clamping or referencing on second rail; allows bidirectional voltage limiting |
| 3 | Common Anode | Shared return path for both Zeners; simplifies PCB routing and reduces component count vs. discrete pair |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Reduces board area by 40 % vs. two discrete SOT23 Zeners while maintaining independent cathode control |
| ±5 % Zener voltage tolerance (C-series) | Meets cost-sensitive industrial and automotive requirements where tight regulation is secondary to robustness |
| AEC-Q101 qualification | Validated for 1000+ hours HTOL, 1000-cycle temperature cycling, and ≥2 kV HBM ESD - suitable for engine control modules |
| Wide operating temperature range | −55 °C to +150 °C ambient enables deployment in transmission control units and ADAS sensor nodes |
| Low 300 pF capacitance at 0 V | Minimizes signal attenuation in 1 MHz sensor interfaces (e.g., analog front-ends for pressure or temperature sensors) |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Analog Input Protection |
|---|---|

Use Value: 300 pF capacitance avoids phase shift in 10 kHz bio-signal bandwidth; −2.7 to +1.2 mV/K TC enables drift compensation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Single Zener, 2.4 V, SOT23, ±5 % - no dual configuration or common anode | Requires two devices for dual-rail use; higher assembly cost and board area | Select when only one regulated rail is needed and lowest unit cost is critical |
| BZX84-C5V1,215 | Single Zener, same 5.1 V/±5 % spec, identical SOT23 package but no second cathode | Lacks bidirectional clamping capability; cannot replace dual functionality without redesign | Choose only for simple unidirectional reference where space permits discrete placement |
Compared with MMBZ5221BS-7-F and BZX84-C5V1,215, the BZB84-C5V1,215 uniquely delivers dual-channel Zener action in one footprint-reducing BOM count by one part and eliminating inter-device matching variance in clamping thresholds.

FAQ
What is the maximum continuous forward current for BZB84-C5V1,215?
The absolute maximum forward current is 200 mA per diode, specified under steady-state conditions. This rating assumes operation within the full ambient temperature range (−55 °C to +150 °C) and accounts for thermal derating above 25 °C ambient per the Rth(j-a) = 417 K/W characteristic. Exceeding this value risks permanent junction damage.
Can BZB84-C5V1,215 be used for bidirectional ESD protection on a data line?
Yes - its dual common-anode topology allows connection between a data line and ground with Pins 1 and 2 tied to the line and Pin 3 grounded, providing symmetrical ±5.1 V clamping. The 40 W non-repetitive peak power rating handles IEC 61000-4-2 Level 4 (15 kV air, 8 kV contact) ESD events when properly laid out with low-inductance grounding.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At 5 mA Zener current, the temperature coefficient ranges from −2.7 mV/K to +1.2 mV/K. Over a 165 K span, this produces a worst-case VZ drift of ±200 mV - verified in Table 8 for BZB84-C5V1. System-level calibration or compensation is recommended for applications requiring <±50 mV total error across temperature.
Is the SOT23 package lead-free and RoHS compliant?
Yes - the BZB84-C5V1,215 uses lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH SVHC regulations. The device is manufactured with matte tin plating over nickel underplate, qualified for standard SnPb and lead-free reflow profiles per J-STD-020.
