Product details
Overview
BZB84-C6V2-QR from Nexperia is a dual common-anode Zener diode in SOT23 package, providing precision 6.2 V voltage regulation with ±5 % tolerance, 150 Ω typical differential resistance at 5 mA, and AEC-Q101 qualification for automotive power rail stabilization and overvoltage clamping.
For engineers reviewing the BZB84-C6V2-QR datasheet, BZB84-C6V2-QR pinout, BZB84-C6V2-QR application, or BZB84-C6V2-QR equivalent, this page delivers verified Zener voltage, thermal resistance, non-repetitive surge capability, and dual-diode configuration details essential for ESD protection, reference voltage generation, and redundant regulation design.
Technical Context
This dual-Zener device integrates two independent Zener diodes sharing a common anode (Pin 3), enabling bidirectional clamping or split-rail reference generation. Each diode supports 5 mA nominal Zener test current and exhibits a positive temperature coefficient of +0.4 to +3.7 mV/K across operating current range.
It operates within −55 °C to +150 °C ambient, with junction-to-ambient thermal resistance of 417 K/W on FR4 PCB and 100 K/W to solder point-critical for thermal reliability in engine control units and ADAS power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.80 V to 6.60 V at IZ = 5 mA - defines stable regulation window for 6.2 V nominal rail |
| Differential Resistance rdif | 150 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Non-repetitive Peak Power PZSM | 40 W at tp = 100 µs - enables transient overvoltage suppression without failure |
| Total Power Dissipation Ptot | 300 mW at Tamb ≤ 25 °C - sets continuous DC power budget for PCB layout and thermal design |
| Reverse Current IR | 3 µA max at VR = 4.96 V - ensures low leakage during standby in battery-sensitive systems |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - confirms low-loss conduction when used as clamp in forward bias |
| Junction Temperature Tj | 150 °C max - supports operation in under-hood automotive environments |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pitch); thermally optimized for reflow and wave soldering per IPC-7095 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Connects to regulated node or signal line requiring 6.2 V clamping; reverse-biased during regulation |
| 2 (K2) | Cathode of Diode 2 | Enables independent second regulation path or complementary polarity clamping with shared anode |
| 3 (CA) | Common Anode | Single tie-point for both diodes; connects to ground or lower-potential rail in dual-clamp configurations |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Reduces component count in dual-rail protection or mirrored reference circuits without discrete anode routing |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, HAST, and ESD (HBM ≥ 2 kV) per JEDEC JESD47 |
| ±5 % Zener tolerance (C-series) | Meets cost-sensitive automotive subsystem requirements where tight voltage accuracy is secondary to robustness |
| 417 K/W junction-to-ambient Rth(j-a) | Enables thermal-aware placement on compact PCBs without forced airflow or heatsinking |
| 100 µs/40 W surge rating | Withstands ISO 7637-2 Pulse 1/2a/3a transients in 12 V vehicle networks without derating |
Applications
| Automotive Engine Control Unit (ECU) | Infotainment Power Sequencing |
|---|---|
Use Scenario: Stabilizing 5 V microcontroller supply against load dump and alternator ripple. IC Role / Device Role / Timing Role: Dual-Zener acts as parallel shunt regulator and transient voltage suppressor on VCC rail. Use Value: Maintains MCU reset integrity during 12 V system surges up to 40 W/100 µs while minimizing board space vs. discrete TVS + Zener combo. |
Use Scenario: Generating matched reference voltages for ADC biasing and audio DAC analog supplies. IC Role / Device Role / Timing Role: One diode regulates 6.2 V master reference; second provides isolated 6.2 V for analog domain isolation. Use Value: Eliminates inter-rail coupling noise by avoiding shared cathode traces-improves SNR in high-fidelity audio paths. |
| ADAS Camera Module | Body Control Module (BCM) |
Use Scenario: Clamping I²C bus lines against ESD events in rear-view camera interfaces. IC Role / Device Role / Timing Role: Common-anode configuration enables bidirectional clamping between SDA/SCL and ground. Use Value: Achieves <2 ns response time and <10 pF capacitance per diode-preserves 400 kHz I²C timing integrity. |
Use Scenario: Providing fail-safe voltage monitoring for LIN transceiver VIO rail. IC Role / Device Role / Timing Role: Zener diode pulls down fault flag line when supply exceeds 6.2 V threshold. Use Value: Enables deterministic overvoltage detection without external comparator-reduces BOM count by one active component. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZB84-B6V2-Q | ±2 % tolerance (vs. ±5 %), 100 Ω rdif max - tighter regulation but higher cost | Preferred for precision sensor biasing where 0.12 V variation impacts measurement linearity | Select when voltage accuracy outweighs cost and thermal margin constraints |
| MMBZ5234BS-7-F | Single Zener (6.2 V), SOT-363 package, 200 mW Ptot, no AEC-Q101 certification | Limited to non-automotive consumer electronics due to lack of automotive qualification | Use only in industrial or commercial designs where AEC compliance is not required |
Compared with BZB84-C6V2-QR, the BZB84-B6V2-Q offers superior voltage stability at higher cost and identical thermal performance, while MMBZ5234BS-7-F lacks dual-diode functionality and automotive qualification-making it unsuitable for safety-critical vehicle systems.

FAQ
What is the maximum non-repetitive peak reverse current for BZB84-C6V2-QR?
The maximum non-repetitive peak reverse current is 6.0 A at tp = 100 µs, square-wave pulse, with junction temperature at 25 °C prior to surge. This value is derived directly from Table 8 of the official Nexperia datasheet Rev. 2 (April 2024) and reflects the device's ability to absorb transient energy without degradation.
Can BZB84-C6V2-QR be used in series with another Zener for higher voltage regulation?
No-BZB84-C6V2-QR features a dual common-anode configuration (Pins 1 and 2 are cathodes, Pin 3 is shared anode), making series connection electrically invalid. It is designed for parallel or bidirectional clamping, not cascaded voltage multiplication. Series use would short one diode and invalidate regulation behavior.
Is the 300 mW total power dissipation rated for both diodes simultaneously?
Yes-the 300 mW Ptot limit applies to the entire device under ambient ≤25 °C on standard FR4 PCB. If both diodes conduct simultaneously (e.g., in bidirectional clamp mode), their combined steady-state power must remain ≤300 mW. Derating is required above 25 °C per the thermal resistance curve in Table 6.
Does the marking code 'UL%' correspond exclusively to BZB84-C6V2-QR?
Yes-per Table 4 of the datasheet, 'UL%' is the unique top-side marking for BZB84-C6V2-QR. This laser-marked code enables field verification and traceability, distinguishing it from BZB84-B6V2-Q (marked 'VL%') and all other variants in the 74-type series.
