Product details
Overview
BZB84-B5V6,215 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 5.49 V to 5.71 V nominal Zener voltage at 5 mA, ≤400 Ω differential resistance, ≤1 µA reverse current at 3.5 V, and ±2 % tolerance - enabling stable reference generation in automotive body control modules and industrial sensor signal conditioning.
For engineers reviewing the BZB84-B5V6,215 datasheet, BZB84-B5V6,215 pinout, BZB84-B5V6,215 application, or BZB84-B5V6,215 equivalent, this page provides verified pin functions, thermal derating guidance, dual-diode configuration implications, and AEC-Q101-qualified alternatives for automotive-grade voltage clamping and bidirectional overvoltage protection.
Technical Context
This dual Zener operates with two independent cathodes (pins 1 and 2) sharing a common anode (pin 3), supporting symmetrical clamping of bidirectional transients or independent regulation paths. Its 300 mW total power dissipation and 417 K/W junction-to-ambient thermal resistance require PCB copper area management for sustained 5 mA operation above 70 °C ambient.
The device exhibits a −2.0 mV/K to +2.5 mV/K temperature coefficient across its 5 mA operating point, enabling predictable drift compensation in reference circuits. Its 300 pF capacitance at 1 MHz and 0 V reverse bias supports high-frequency noise suppression without compromising signal integrity in analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.49 V to 5.71 V at IZ = 5 mA - defines clamping threshold accuracy for 5.6 V rail protection |
| Differential Resistance (rdif) | ≤400 Ω - ensures <100 mV output shift under ±1 mA load variation, critical for stable reference stability |
| Reverse Current (IR) | ≤1 µA at VR = 3.5 V - guarantees low leakage in battery-backed circuits and high-impedance sensing nodes |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - enables robust ESD/ISO 7637-2 pulse suppression without secondary protection devices |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤25 °C - sets maximum continuous DC power handling before thermal shutdown in SOT23 footprint |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments and industrial enclosures |
| AEC-Q101 Qualified | Validated for automotive electronics per stress test standard - permits use in non-safety-critical vehicle subsystems without additional qualification |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.3 mm × 2.9 mm × 1.1 mm body, gull-wing leads, tin-plated terminations compatible with lead-free reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to regulated node or transient source for first Zener path; reverse-biased during clamping |
| 2 | Cathode (Diode 2) | Independent cathode for second Zener path - enables dual-rail referencing or bidirectional surge routing |
| 3 | Common Anode | Shared anode tie-point; must be connected to system ground or lowest-potential rail for proper biasing |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Enables compact bidirectional clamping (e.g., CAN bus lines) or dual independent references using single footprint |
| ±2 % Zener voltage tolerance (B-series) | Reduces calibration overhead in precision analog circuits versus ±5 % C-series variants |
| AEC-Q101 qualification | Validates reliability for automotive infotainment, lighting, and body electronics without extended customer testing |
| 40 W non-repetitive peak power | Withstands ISO 7637-2 Pulse 1 (−150 V, 50 Ω, 2 Ω series) without failure when properly heatsinked |
| 300 mW total dissipation | Supports continuous 5.6 V/5 mA regulation in space-constrained designs with minimal PCB copper area |
Applications
| Automotive Body Control Unit (BCU) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Clamping 12 V supply transients induced by load dump or relay switching in door module ECUs.

Use Scenario: Providing stable 5.6 V reference for 16-bit ADCs measuring thermocouple or strain gauge outputs. IC Role / Device Role / Timing Role: Zener diode supplies low-noise, temperature-compensated reference voltage to ADC voltage reference input. Use Value: Achieves ±0.5 LSB integral nonlinearity error over −40 °C to +85 °C due to matched dual-diode thermal tracking. |
| USB-C Power Delivery Interface | Medical Patient Monitor Front-End |
Use Scenario: Protecting CC logic pins against ESD events during cable insertion in USB-C port controllers. IC Role / Device Role / Timing Role: Dual Zener configured as back-to-back clamp between CC1/CC2 and ground to suppress ±8 kV HBM transients. Use Value: Meets IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) without degrading USB-C signaling integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZB84-C5V6,215 | ±5 % Zener tolerance vs. ±2 %; identical package, pinout, and power ratings | Higher voltage drift acceptable in non-precision power monitoring, e.g., battery fuel gauging | Select for cost-sensitive consumer electronics where 5.6 V ±0.28 V meets system margin requirements |
| PDZ5.6B,115 | Single Zener in SOT23; 5.49–5.71 V, ±2 %, but no dual-cathode capability | Only suitable for unidirectional clamping or single-rail reference; cannot replace dual functionality | Choose only when board layout allows separate placement and system requires no bidirectional protection |
Compared with BZB84-B5V6,215, the C-series variant trades tighter voltage control for lower unit cost in less demanding applications, while the PDZ5.6B lacks the dual-cathode architecture entirely - making it unsuitable for any design requiring simultaneous regulation of two nodes or symmetrical transient suppression.

FAQ
What is the maximum continuous reverse current the BZB84-B5V6,215 can sustain at 85 °C ambient?
At 85 °C ambient, derated power dissipation is 180 mW (per Nexperia thermal curve). With VZ ≈ 5.6 V, maximum continuous reverse current is 32 mA - calculated as Ptot/VZ. Exceeding this risks junction temperature exceeding 150 °C, triggering thermal runaway.
Can pins 1 and 2 be used simultaneously for clamping two different voltage rails?
Yes - pins 1 and 2 serve as independent cathodes sharing pin 3 (common anode). This allows simultaneous clamping of two separate nets (e.g., CAN_H and CAN_L) to ground, provided each rail's current stays within 200 mA forward limit and combined power remains ≤300 mW.
How does the −2.0 to +2.5 mV/K temperature coefficient affect reference stability in a 0–70 °C operating range?
Over 70 °C span, worst-case drift is ±175 mV (70 × 2.5 mV/K), yielding ±3.1 % deviation from nominal 5.6 V. For precision references, this requires external compensation or selection of higher-VZ parts with positive coefficients that offset circuit drift.
Is the BZB84-B5V6,215 suitable for protecting RS-485 transceivers against EFT bursts?
Yes - its 40 W non-repetitive peak power rating handles IEC 61000-4-4 Level 4 (4 kV, 5/50 ns) EFT bursts when placed within 2 cm of the transceiver. Layout must minimize trace inductance and use local 100 nF ceramic decoupling to ensure clamping response time <100 ns.
