Product details
Overview
BZB84-B10-QR from Nexperia is a dual Zener diode in SOT23 package with common-anode configuration, 10 V nominal Zener voltage (±2 % tolerance), 300 mW total power dissipation, and AEC-Q101 qualification for automotive voltage regulation and reference applications.
For engineers reviewing the BZB84-B10-QR datasheet, BZB84-B10-QR pinout, BZB84-B10-QR application, or BZB84-B10-QR equivalent, this device serves as a dual-voltage reference in compact automotive ECUs, sensor biasing circuits, and overvoltage protection networks where space-constrained dual-Zener functionality and automotive-grade reliability are required.
Technical Context
This dual common-anode Zener diode integrates two independent 10 V Zener elements sharing one anode terminal, enabling simultaneous or independent voltage clamping/reference functions in a single SOT23 footprint. Each diode supports 5 mA test current and exhibits 150 Ω typical differential resistance at IZ = 5 mA.
It operates across –55 °C to +150 °C ambient temperature, with thermal resistance from junction to ambient of 417 K/W on standard FR4 PCB, and is rated for non-repetitive peak reverse power dissipation up to 40 W (100 µs square wave, Tj = 25 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.80 V to 10.20 V at IZ = 5 mA - tight ±2 % tolerance enables precise dual-reference generation without external trimming |
| Total Power Dissipation Ptot | 300 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard FR4 PCB |
| Differential Resistance rdif | 150 Ω max at IZ = 5 mA - low dynamic impedance ensures stable regulation under varying load conditions |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - enables low-loss forward conduction when used in bidirectional clamp configurations |
| Non-repetitive Peak Reverse Power | 40 W at tp = 100 µs - supports transient surge suppression in automotive load-dump or ISO 7637-2 pulse scenarios |
| Junction Temperature Range | –55 °C to +150 °C - validated for under-hood automotive environments and industrial control systems |
Pinout & Package
SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch, 3-terminal configuration with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Anode-referenced 10 V Zener cathode; connects to regulated node or clamping point for first diode |
| 2 | K2 (Cathode 2) | Independent 10 V Zener cathode; allows separate regulation paths or dual-rail referencing |
| 3 | CA (Common Anode) | Shared anode connection; ties both Zeners to ground or common reference potential |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Enables compact dual-voltage reference or bidirectional clamping in one SOT23 footprint, reducing board area by ~40% vs. discrete dual-Zener solutions |
| AEC-Q101 qualification | Validated for automotive use per stress-test requirements including HTGB, HTRB, and ESD-HBM ≥ 2 kV - suitable for engine control, ADAS sensors, and body electronics |
| ±2 % Zener tolerance (B-series) | Eliminates need for post-assembly calibration in precision biasing applications such as op-amp reference inputs or ADC voltage references |
| Low thermal resistance (Rth(j-sp) = 100 K/W) | Supports reliable heat transfer to solder joints during sustained 300 mW operation, minimizing thermal runaway risk in high-density layouts |
| 100 µs 40 W surge rating | Withstands ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump) transients without degradation when properly decoupled |
Applications
| Automotive Engine Control Unit (ECU) Reference | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Providing stable dual reference voltages for analog front-end comparators and ADC biasing in 12 V vehicle ECUs. IC Role / Device Role / Timing Role: Dual Zener reference source - one diode sets 10 V rail for sensor excitation, the other provides 10 V reference for ADC conversion accuracy. Use Value: Maintains <±0.2 V drift over –40 °C to +125 °C operating range, ensuring consistent sensor measurement linearity without external trimming. |
Use Scenario: Biasing bridge-based pressure/temperature sensors in factory automation modules with 24 V supply rails. IC Role / Device Role / Timing Role: Dual-voltage clamp - one diode protects amplifier input against overvoltage, the other stabilizes reference voltage for ratiometric scaling. Use Value: Simultaneous 10 V clamping and referencing reduces component count by one Zener diode and associated passive filtering, lowering BOM cost and layout complexity. |
| Automotive Body Control Module (BCM) Overvoltage Protection | Consumer Appliance Power Supply Monitoring |
Use Scenario: Protecting microcontroller I/O pins and CAN transceiver bias rails from load-dump transients in BCM power domains. IC Role / Device Role / Timing Role: Fast-response dual Zener clamp - common anode tied to ground, cathodes connected to protected nodes to shunt surges above 10 V. Use Value: Withstands 40 W non-repetitive surges (100 µs) while maintaining <100 ns response time, preventing latch-up in downstream logic. |
Use Scenario: Monitoring 12 V DC adapter output in smart home hubs to detect brown-out or overvoltage faults before system reset. IC Role / Device Role / Timing Role: Dual-threshold detector - one Zener triggers undervoltage alarm at 10 V, the other enables overvoltage shutdown at same threshold via comparator hysteresis. Use Value: Single-device dual-threshold detection improves fault coverage accuracy by eliminating inter-component voltage mismatch errors inherent in discrete solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5240BS | Single 10 V Zener in SOT23; no dual configuration or common-anode topology | Requires two devices plus routing for dual-reference use; lacks integrated common-anode convenience | Select when only one 10 V reference is needed and board space permits discrete placement |
| Vishay BZX84-C10-TP | Single Zener, ±5 % tolerance (C-series), no AEC-Q101 qualification | Not rated for automotive use; higher voltage variation impacts precision sensing accuracy | Acceptable for cost-sensitive consumer applications where AEC-Q101 and tight tolerance are not required |
Compared with MMBZ5240BS and BZX84-C10-TP, BZB84-B10-QR uniquely delivers dual 10 V references in one AEC-Q101-qualified SOT23 package with ±2 % tolerance - essential for space-constrained automotive and industrial designs requiring matched dual-voltage stability.

FAQ
What is the maximum continuous reverse current for BZB84-B10-QR at 25 °C?
The device is rated for 5 mA Zener test current (IZ = 5 mA) per diode, with maximum continuous reverse current limited by power dissipation: at 10 V, IZ ≤ 30 mA ensures Ptot stays within 300 mW on FR4 PCB at Tamb = 25 °C. Exceeding this requires derating per thermal characteristics table.
Can BZB84-B10-QR be used in a series-connected dual-Zener configuration?
No - its internal structure is strictly dual common-anode; both cathodes are isolated, but the anodes are internally joined. Series connection would short the anodes and disable one diode. It is intended for parallel reference or independent clamping with shared ground reference.
How does the ±2 % tolerance affect performance in precision voltage reference applications?
At 10 V nominal, ±2 % means VZ ranges from 9.80 V to 10.20 V. This guarantees worst-case deviation of ±0.2 V, sufficient for 12-bit ADC references (LSB ≈ 2.44 mV at 10 V) and comparator thresholds where <±0.5 % additional error budget remains for temperature drift and noise.
Is the SOT23 package lead-free and RoHS compliant?
Yes - BZB84-B10-QR is manufactured using lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with homogeneous material declarations available upon request through Nexperia's compliance portal.
