Product details
Overview
BZB84-B5V6-QR from Nexperia is a dual Zener diode in SOT23 package with common-anode configuration, rated for 5.6 V ±2 % nominal Zener voltage, 400 Ω typical differential resistance at 5 mA, and −2.0 to +2.5 mV/K temperature coefficient - used for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the BZB84-B5V6-QR datasheet, BZB84-B5V6-QR pinout, BZB84-B5V6-QR application, or BZB84-B5V6-QR equivalent, key selection criteria include dual-Zener tolerance matching, AEC-Q101 qualification, non-repetitive surge capability (40 W), and thermal resistance (100 K/W junction-to-solder-point) in space-constrained SMT designs.
Technical Context
This dual common-anode Zener diode integrates two matched 5.6 V regulation elements sharing one anode terminal, enabling bidirectional clamping or dual-rail referencing without external interconnects. Its −2.0 to +2.5 mV/K temperature coefficient ensures stable regulation across −55 °C to +150 °C ambient range.
Designed per IEC 60134 absolute maximum ratings, it supports 200 mA forward current per diode and withstands 40 W non-repetitive reverse surges (tp = 100 µs, square wave) while maintaining ≤300 mW total device power dissipation on FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.49 V to 5.71 V at IZ = 5 mA - tight ±2 % tolerance enables accurate dual-rail voltage setting |
| Differential Resistance (rdif) | 400 Ω max at IZ = 5 mA - low impedance improves regulation stability under load variation |
| Temperature Coefficient (SZ) | −2.0 to +2.5 mV/K - near-zero drift region supports stable operation from −40 °C to +125 °C |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - handles transient surges in automotive 12 V systems |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - defines continuous DC power budget for thermal design |
| Junction Temperature (Tj) | 150 °C max - sets upper thermal limit for reliability in under-hood environments |
| Reverse Current (IR) | 1 µA max at VR = 4.0 V - ensures low leakage during standby in battery-sensitive applications |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm, 1.9 mm pitch); thermally optimized for reflow soldering with 100 K/W junction-to-solder-point resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Connects to regulated node 1; reverse-biased during Zener operation |
| 2 (K2) | Cathode of Diode 2 | Connects to regulated node 2; enables independent clamping of two signals |
| 3 (CA) | Common Anode | Shared anode connection; simplifies PCB layout for dual-Zener topology |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode Zener topology | Eliminates need for external anode tie, reducing component count and board area in dual-rail protection circuits |
| AEC-Q101 qualified | Validated for automotive use including engine control units, body electronics, and ADAS power domains |
| ±2 % Zener voltage tolerance (B-series) | Enables tighter regulation margins than ±5 % C-series, critical for sensor reference accuracy |
| 40 W non-repetitive surge rating | Withstands ISO 7637-2 pulse 1/2a/2b transients without degradation in 12 V vehicle networks |
| Low thermal resistance (100 K/W j-sp) | Supports higher sustained power in compact layouts by efficiently transferring heat to PCB copper |
Applications
| Automotive ECU Power Rail Protection | Industrial Sensor Reference Voltage |
|---|---|
Use Scenario: Clamping transients on 5 V microcontroller supply rail in engine control modules. IC Role / Device Role / Timing Role: Dual-Zener provides bidirectional overvoltage/undervoltage clamping at shared anode node. Use Value: Prevents MCU reset or latch-up during load-dump events while maintaining <1 µA leakage in sleep mode. |
Use Scenario: Generating stable 5.6 V reference for analog front-end of pressure sensors. IC Role / Device Role / Timing Role: Zener diode supplies precision bias voltage to op-amp input stage. Use Value: −2.0 to +2.5 mV/K tempco ensures <0.5 % reference drift over −40 °C to +105 °C operating range. |
| USB-C Port Overvoltage Clamp | Redundant Power Monitor Circuit |
Use Scenario: Protecting USB-C VBUS line against accidental 12 V insertion in docking stations. IC Role / Device Role / Timing Role: One Zener clamps positive overvoltage; second clamps negative fault via common anode. Use Value: 40 W surge rating absorbs 100 µs pulses without failure; 0.9 V forward drop limits conduction loss. |
Use Scenario: Monitoring dual 5 V supplies in safety-critical PLC I/O modules. IC Role / Device Role / Timing Role: Each cathode monitors separate rail; common anode enables single-point fault detection. Use Value: Matched 5.6 V thresholds ensure simultaneous trip point for redundant supply validation logic. |
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-Q | ±5 % Zener tolerance vs. ±2 %; higher 500 Ω rdif at 5 mA | Acceptable for non-critical biasing where cost sensitivity outweighs regulation precision | Select when tighter voltage matching between diodes is not required and lower unit cost is prioritized |
| MMBZ5232BS | Single-diode SOT23 package; no common-anode dual configuration; 5.6 V ±5 % | Requires external anode tie for dual-rail use, increasing layout complexity and parasitic inductance | Choose only if existing design uses discrete Zeners and board real estate allows added trace routing |
Compared with BZB84-C5V6-Q, the BZB84-B5V6-QR offers tighter voltage matching and lower dynamic impedance for precision references; versus MMBZ5232BS, its integrated dual-anode architecture reduces component count and improves surge response symmetry in bidirectional clamp designs.

FAQ
What is the maximum non-repetitive surge current for BZB84-B5V6-QR?
The device supports up to 6.0 A non-repetitive peak reverse current (IZSM) at 100 µs pulse width and 25 °C initial junction temperature, corresponding to its 40 W peak power rating. This value is confirmed in Table 8 of the datasheet under "Non-repetitive peak reverse current" for the B-series 5.6 V variant.
Can BZB84-B5V6-QR be used in place of two separate single-Zener diodes?
Yes - its dual common-anode configuration replaces two discrete 5.6 V Zeners with shared anode connection, reducing footprint by ~40 % and eliminating layout asymmetry. Pin 3 (CA) serves as the unified anode, while Pins 1 and 2 provide independent cathodes for separate regulation paths.
Is the temperature coefficient linear across the full operating range?
No - the temperature coefficient varies with Zener voltage and test current; for BZB84-B5V6-QR, it ranges from −2.0 to +2.5 mV/K at IZ = 5 mA (Table 8), reflecting curvature in the VZ vs. Tj curve. Figure 7 shows this nonlinearity across 25–150 °C.
Does the SOT23 package support automated optical inspection (AOI)?
Yes - the SOT23 outline (Fig. 11) features defined solder pad geometry and consistent marking (VK% per Table 4), enabling reliable AOI detection. The 1.9 mm pin pitch and 0.45 mm lead thickness meet IPC-A-610 Class 2/3 requirements for automated visual verification.
