Product details
Overview
BZB84-C2V7-Q from Nexperia is a dual common-anode Zener diode in SOT23 package, providing precise 2.7 V voltage regulation with ±5 % tolerance and 600 Ω differential resistance at 5 mA for automotive power rail clamping and reference stabilization. It supports non-repetitive surge handling up to 40 W and operates across −55 °C to +150 °C ambient range.
For engineers reviewing the BZB84-C2V7-Q datasheet, BZB84-C2V7-Q pinout, BZB84-C2V7-Q application, or BZB84-C2V7-Q equivalent, this page delivers verified Zener voltage, thermal resistance, peak surge capability, AEC-Q101 qualification status, and dual-diode configuration details essential for automotive voltage reference and overvoltage protection design.
Technical Context
This dual-Zener device integrates two independent Zener junctions sharing a common anode (Pin 3), enabling compact dual-rail regulation or complementary clamping in space-constrained PCB layouts. Its 2.7 V nominal Zener voltage is specified at 5 mA test current with temperature coefficient of −3.5 mV/K to 0.0 mV/K.
The device complies with AEC-Q101 stress testing for discrete semiconductors and exhibits 417 K/W junction-to-ambient thermal resistance on FR4 PCB - critical for thermal reliability in under-hood automotive modules where ambient temperatures reach +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.50 V to 2.90 V at IZ = 5 mA - defines tight regulation window for low-voltage microcontroller supply monitoring |
| Tolerance | ±5 % - C-grade accuracy suitable for non-critical biasing and clamping where cost-sensitive automotive designs prioritize robustness over precision |
| Differential Resistance rdif | 600 Ω max at IZ = 5 mA - ensures stable regulation under moderate load variation in sensor interface circuits |
| Non-repetitive Peak Power PZSM | 40 W at tp = 100 µs - enables transient suppression of ESD or load-dump spikes without failure |
| Total Power Dissipation Ptot | 300 mW at Tamb ≤ 25 °C - sets continuous DC power limit for steady-state voltage reference operation |
| Junction Temperature Range | −55 °C to +150 °C - supports operation in engine control units and body electronics exposed to extreme thermal cycling |
| AEC-Q101 Qualified | Yes - validated for automotive use per stress test standard, including HTOL, TC, HAST, and ESD-HBM ≥ 2 kV |
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 of Diode 1 | Connects to regulated node requiring 2.7 V clamping; reverse-biased during Zener operation |
| 2 (K2) | Cathode of Diode 2 | Enables independent second 2.7 V reference path or dual-rail protection without external components |
| 3 (CA) | Common Anode | Shared anode connection simplifies PCB routing and reduces footprint versus two discrete Zeners |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Reduces board area by 40 % vs. two separate SOT23 Zeners while maintaining independent cathode access |
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine management and ADAS power domains |
| 40 W non-repetitive surge rating | Withstands ISO 7637-2 Pulse 1/2a/5a transients without derating in typical 12 V vehicle systems |
| Low thermal resistance | 100 K/W junction-to-solder-point enables direct thermal coupling to copper pour for enhanced surge survivability |
| Stable temperature coefficient | −3.5 mV/K to 0.0 mV/K minimizes drift across −40 °C to +125 °C operating range in battery monitoring circuits |
Applications

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 |
|---|---|---|---|
| ON Semiconductor MMBZ5223BS | Single 2.7 V Zener in SOT23; no dual configuration; ±5 % tolerance; 200 mW Ptot | Lacks dual-cathode flexibility; requires two devices for same functionality; lower surge rating (25 W) | Select when only one regulated node is needed and board space allows duplication |
| Vishay SMBZ5223-E3/52 | Single 2.7 V Zener in SOD-123; ±5 %; 500 mW Ptot; higher thermal mass but larger footprint | Superior power handling but incompatible pinout; no common-anode advantage for multi-rail designs | Prefer for high-temperature industrial environments where 500 mW continuous dissipation is required |
Compared with MMBZ5223BS and SMBZ5223-E3/52, BZB84-C2V7-Q uniquely delivers dual 2.7 V regulation in one SOT23 footprint with AEC-Q101 validation and 40 W surge capability - making it optimal for automotive multi-rail systems where space, reliability, and transient immunity are jointly constrained.

FAQ
What is the maximum continuous forward current for BZB84-C2V7-Q?
The absolute maximum forward current is 200 mA per diode, as defined in the limiting values table. This rating applies at Tamb ≤ 25 °C with proper PCB thermal relief; derating is required above 25 °C ambient per the Rth(j-a) = 417 K/W characteristic.
Can BZB84-C2V7-Q be used in parallel configurations?
No - the device is not characterized for parallel operation. Its ±5 % Zener voltage tolerance and mismatched temperature coefficients between the two diodes can cause current imbalance and thermal runaway; each cathode must be used independently with its own current-limiting resistor.
Is the common anode pin electrically isolated from the package tab?
Yes - the SOT23 package has no internal thermal pad or exposed metal tab; Pin 3 (CA) is fully insulated and serves solely as the electrical common anode connection with no thermal conduction path to PCB except through solder joints on Pins 1 and 2.
How does the 2.7 V Zener voltage perform at elevated junction temperatures?
At IZ = 5 mA, the temperature coefficient ranges from −3.5 mV/K to 0.0 mV/K, meaning the Zener voltage decreases by up to 3.5 mV per Kelvin rise - resulting in ~−175 mV shift from 25 °C to 125 °C junction temperature, which must be accounted for in precision reference designs.
