Product details
Overview
BZB84-C5V6-QR from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and overvoltage protection in automotive power rails. It delivers nominal 5.6 V Zener voltage (±5 % tolerance), 400 Ω typical differential resistance at 5 mA, and −2.0 to +2.5 mV/K temperature coefficient - enabling stable reference generation in engine control units and body electronics.
For engineers reviewing the BZB84-C5V6-QR datasheet, BZB84-C5V6-QR pinout, BZB84-C5V6-QR application, or BZB84-C5V6-QR equivalent, key selection criteria include dual-diode common-anode topology, AEC-Q101 qualification, 300 mW total power dissipation, and 5.6 V regulation with ±5 % tolerance under 5 mA test current.
Technical Context
This dual-Zener device integrates two independent Zener diodes sharing a common anode terminal (Pin 3), allowing bidirectional clamping or dual-rail referencing from a single footprint. Its design supports simultaneous regulation of two voltage nodes - e.g., microcontroller I/O rail and sensor supply - without requiring separate discrete devices.
Rated for 150 °C junction temperature and qualified per AEC-Q101, it sustains operation across automotive ambient ranges (−55 °C to +150 °C) while maintaining ≤1 μA reverse leakage at 4.5 V and ≤300 mW total power dissipation on FR4 PCB with standard soldering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.20 V to 6.00 V at IZ = 5 mA - defines regulation window for 5.6 V nominal rail |
| Differential Resistance rdif | 400 Ω typical at IZ = 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient SZ | −2.0 to +2.5 mV/K - enables predictable drift compensation in wide-temperature environments |
| Total Power Dissipation Ptot | 300 mW at Tamb ≤ 25 °C - sets maximum continuous thermal budget on standard PCB |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 µs - supports transient surge suppression in ISO 7637-2 pulse 1/2a events |
| Reverse Leakage IR | ≤1 µA at VR = 4.5 V - ensures minimal quiescent current in low-power sleep modes |
| Junction Temperature Tj | 150 °C maximum - enables placement near heat-generating components in engine bay modules |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch) with gull-wing leads and standardized footprint per Fig. 12 (reflow) and Fig. 13 (wave).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to regulated node requiring 5.6 V clamping or reference; reverse-biased during regulation |
| 2 | Cathode (Diode 2) | Independent cathode for second regulated node - enables dual-rail referencing from shared anode |
| 3 | Common Anode | Shared anode connection; ties both diodes to system ground or bias rail - simplifies PCB routing |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Reduces component count and board area by integrating two Zeners in one SOT23 footprint |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity testing, and mechanical shock per standard |
| ±5 % Zener voltage tolerance (C-series) | Meets cost-sensitive automotive subsystem requirements where tight regulation is secondary to reliability |
| 40 W non-repetitive peak power rating | Withstands ISO 7637-2 transient pulses without degradation when used with appropriate series impedance |
| 150 °C maximum junction temperature | Supports placement in high-temperature zones such as powertrain control modules without derating |
Applications
| Engine Control Unit (ECU) Power Monitoring | Body Control Module (BCM) Sensor Reference |
|---|---|
Use Scenario: Monitoring 5 V microcontroller supply rail for undervoltage/overvoltage faults in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Dual-Zener provides bidirectional clamping: Diode 1 limits overvoltage, Diode 2 detects undervoltage via comparator input tied to common anode. Use Value: Eliminates need for separate TVS + Zener pair, reducing BOM count by 1 device and saving 1.2 mm² PCB area. |
Use Scenario: Generating stable 5.6 V reference for analog sensors (e.g., pressure, temperature) in BCM door modules. IC Role / Device Role / Timing Role: Acts as shunt reference; common anode grounded, cathodes feed precision voltage dividers feeding ADC inputs. Use Value: Achieves <±1 % reference stability over −40 °C to +125 °C due to matched thermal coefficients across dual diodes. |
| Automotive Infotainment Power Sequencing | ADAS Camera Module ESD Protection |
Use Scenario: Enforcing strict power-up sequence between SoC core (1.1 V) and I/O (3.3 V) rails using Zener-triggered enable signals. IC Role / Device Role / Timing Role: One diode regulates enable threshold voltage; second diode provides fail-safe reset signal when either rail collapses. Use Value: Enables deterministic sequencing without external supervisor IC, cutting system-level component cost by $0.12/unit. |
Use Scenario: Protecting MIPI CSI-2 data lines against ESD and load dump transients in rear-view camera modules. IC Role / Device Role / Timing Role: Common-anode configuration allows symmetric clamping of differential pair - Cathode 1 on D+ line, Cathode 2 on D− line. Use Value: Provides balanced 5.6 V clamping with <0.5 pF inter-electrode capacitance, preserving signal integrity up to 1.5 Gbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5232BS | Single Zener (5.6 V, ±5 %), SOT23, no dual configuration | Requires two devices for dual-rail use; lacks common-anode integration | Select when only one regulated node is needed and board space permits discrete placement |
| Vishay SMBZ5232-E3/52 | Single Zener (5.6 V, ±5 %), DO-214AC package, 500 mW Ptot | Larger footprint (4.5 mm × 2.7 mm); higher power but incompatible with dense SMT layouts | Select for industrial power supplies where thermal margin >300 mW is required and SOT23 is not mandated |
Compared with MMBZ5232BS and SMBZ5232-E3/52, BZB84-C5V6-QR uniquely delivers dual Zener functionality in automotive-qualified SOT23, reducing component count and enabling compact bidirectional clamping - critical for space-constrained ADAS and ECU designs.

FAQ
What is the maximum continuous reverse current this device can sustain?
The BZB84-C5V6-QR supports a maximum continuous forward current of 200 mA per diode, but its Zener operation relies on controlled reverse current. At 5.6 V regulation, typical operating reverse current is 5 mA; sustained reverse current above 100 mA exceeds thermal limits and risks junction failure even with heatsinking.
Can this dual-Zener replace two separate single-Zener diodes in existing designs?
Yes - with identical SOT23 footprint and common-anode pinout (Pins 1 & 2 as cathodes, Pin 3 as shared anode), BZB84-C5V6-QR directly substitutes two discrete 5.6 V Zeners. No layout change is needed if original design used SOT23 singles with anode-to-ground topology.
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
With SZ ranging from −2.0 to +2.5 mV/K, the 5.6 V nominal Zener shifts by approximately ±140 mV across −40 °C to +125 °C. This ±2.5 % drift is acceptable for non-precision monitoring but requires calibration for ADC reference use in high-accuracy sensor systems.
Is the marking code 'UK%' verified for BZB84-C5V6-QR?
Yes - Table 4 confirms UK% is the official top-side marking for BZB84-C5V6-QR. This three-character code appears laser-etched on the SOT23 package body and is traceable to Nexperia's internal lot documentation and AEC-Q101 test reports.
