Product details
Overview
BZB84-B6V2-QR from Nexperia is a dual Zener diode in SOT23 package with common-anode configuration, 6.2 V nominal Zener voltage (±2 % tolerance), 150 Ω typical differential resistance at 5 mA, and AEC-Q101 qualification for automotive voltage regulation and clamping functions.
For engineers reviewing the BZB84-B6V2-QR datasheet, BZB84-B6V2-QR pinout, BZB84-B6V2-QR application, or BZB84-B6V2-QR equivalent, this device serves as a space-efficient dual-voltage reference for rail stabilization, overvoltage protection, and precision biasing in compact automotive ECUs and industrial sensor interfaces.
Technical Context
This dual-common-anode Zener diode integrates two independent 6.2 V regulation elements sharing a single anode terminal, enabling symmetrical clamping or dual-rail referencing without discrete pairing. Its ±2 % voltage tolerance and low 150 Ω dynamic impedance ensure stable regulation under 5 mA test current.
Qualified to AEC-Q101 and rated for −55 °C to +150 °C ambient operation, it supports automotive-grade reliability with 300 mW total power dissipation and 40 W non-repetitive peak reverse power handling at 100 µs pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V to 6.32 V at IZ = 5 mA - tight ±2 % tolerance enables accurate dual-rail voltage setting |
| Differential Resistance (rdif) | 150 Ω max at IZ = 5 mA - low impedance ensures minimal voltage shift under load variation |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - low conduction loss in forward-biased protection paths |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - defines continuous thermal limit on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - supports transient surge suppression in CAN/LIN bus interfaces |
| Temperature Coefficient (SZ) | +0.4 mV/K to +3.7 mV/K - positive drift improves stability across automotive temperature range |
| Reverse Current (IR) | ≤ 3 µA at VR = 4.96 V - low leakage preserves battery life in always-on 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 Figure 12 (reflow) and Figure 13 (wave).
| 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; ties both diodes to reference potential (e.g., ground or supply rail) |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zener configuration | Two independent 6.2 V Zeners in one SOT23 - reduces board area vs. discrete pair by >40 % |
| AEC-Q101 qualification | Stress-tested for automotive environments - validated for 150 °C junction temp and thermal cycling |
| ±2 % voltage tolerance (B-series) | Tighter than standard C-series (±5 %) - eliminates post-production trimming in precision bias circuits |
| Low differential resistance | 150 Ω max at 5 mA - maintains <10 mV output shift across 1–10 mA load range |
| High surge robustness | 40 W non-repetitive peak power - withstands ISO 7637-2 Pulse 1/2a transients without derating |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Regulating 5 V and 3.3 V reference rails for microcontroller I/O and analog front-end circuitry in door module ECUs. IC Role / Device Role / Timing Role: Dual Zener provides simultaneous clamping and voltage limiting for both rails using shared ground return path. Use Value: Eliminates need for two separate Zeners and associated layout routing, reducing component count and improving EMI immunity via minimized loop area. |
Use Scenario: Protecting ADC input pins from overvoltage events in 4–20 mA current-loop transmitters exposed to field wiring surges. IC Role / Device Role / Timing Role: Acts as bidirectional clamp-common anode grounded, cathodes tied to signal line and reference-limiting excursion to ±6.2 V. Use Value: Prevents ADC saturation and latch-up during 1 kV fast-transient events while maintaining <3 µA leakage at operating voltage. |
| Automotive LIN Bus Transceiver Protection | Compact DC-DC Feedback Divider Stabilization |
Use Scenario: Clamping LIN bus line voltage during load-dump or jump-start conditions in seat control units. IC Role / Device Role / Timing Role: Common-anode configuration connects CA to VBAT, K1/K2 to LIN line and pull-up node-clamping both directions to VBAT ±6.2 V. Use Value: Enables single-device bidirectional protection compliant with LIN Physical Layer Specification v2.2A surge requirements. |
Use Scenario: Stabilizing feedback divider network in isolated flyback converters where output voltage sensing requires high-impedance, low-drift references. IC Role / Device Role / Timing Role: One Zener sets upper divider ratio; second provides local 6.2 V reference for optocoupler bias, decoupling from primary-side noise. Use Value: Improves output regulation accuracy by 0.5 % over temperature versus single-Zener solutions due to matched thermal drift in monolithic die. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3020LSD-13 | Single N-channel MOSFET (30 V, 4.2 A), not a Zener - incompatible function | N/A - not a voltage reference device | Not suitable: functional mismatch; no Zener capability |
| BZX84-C6V2-Q | Single Zener, same 6.2 V rating but ±5 % tolerance and no dual configuration | Requires two devices for dual-rail use; higher board area and mismatched thermal drift | Select only if dual functionality is unnecessary and cost-per-device is prioritized over layout efficiency |
Compared with BZB84-B6V2-QR, BZX84-C6V2-Q lacks dual integration and tighter tolerance, increasing design complexity for multi-rail systems; no viable MOSFET-based alternative exists for Zener regulation function.

FAQ
What is the maximum continuous reverse current for BZB84-B6V2-QR at 25 °C?
The device has no specified maximum continuous reverse current; instead, its steady-state operation is governed by total power dissipation (300 mW). At 6.2 V Zener voltage, this limits average reverse current to approximately 48 mA when ambient temperature is ≤25 °C on standard FR4 PCB. Derating applies above 25 °C per Rth(j-a) = 417 K/W.
Can BZB84-B6V2-QR be used in bidirectional TVS configurations?
No - it is a Zener diode, not a TVS. While it clamps in reverse bias, its 40 W non-repetitive surge rating applies only to 100 µs pulses and lacks the low clamping voltage, high peak current, and standardized surge waveforms (e.g., 8/20 µs) defined for TVS diodes. Use dedicated automotive TVS like PESD5V0S1BA for IEC 61000-4-2/5 compliance.
How does the common-anode configuration affect PCB layout in dual-rail designs?
The common-anode (CA) pin must connect to a stable reference node-typically ground or a clean supply rail-while K1 and K2 route separately to their respective regulated nodes. This allows shared thermal mass and minimizes ground bounce between rails, but requires careful isolation of K1/K2 traces to prevent coupling. Standard SOT23 reflow footprint (Figure 12) ensures manufacturability.
Is the 6.2 V Zener voltage specified at DC or pulsed test conditions?
Zener voltage is specified at DC test condition: IZ = 5 mA, Tj = 25 °C. The datasheet's "Characteristics" tables (Table 8) explicitly state "Tj = 25 °C unless otherwise specified", and all VZ min/max values are derived from DC measurements. Pulse testing applies only to surge parameters (e.g., PZSM, IZSM).
