Product details
Overview
BZB784-C6V2-QX from Nexperia is a dual Zener voltage regulator diode in SOT323 (SC-70) package, configured with common anode and two independent cathodes (K1/K2), delivering 6.2 V nominal regulation at ±5% tolerance, 3 µA reverse leakage at VR = 6.2 V, and 40 Ω typical differential resistance at IZ = 5 mA - used for precision biasing and ESD protection in automotive sensor interfaces.
For engineers reviewing the BZB784-C6V2-QX datasheet, BZB784-C6V2-QX pinout, BZB784-C6V2-QX application, or BZB784-C6V2-QX equivalent, this page delivers verified electrical parameters, validated thermal performance, AEC-Q101 qualification status, and real-world implementation guidance for dual-rail voltage clamping and low-power reference design.
Technical Context
This dual-Zener device integrates two independent 6.2 V regulation elements sharing a common anode terminal, enabling symmetrical bidirectional clamping or split-rail reference generation without external interconnects. Its 200 mA forward current rating and 40 W non-repetitive peak reverse power dissipation support transient surge suppression per ISO 7637-2 Pulse 1/2a.
The device exhibits +2.2 mV/K temperature coefficient at IZ = 5 mA and 200 pF diode capacitance at f = 1 MHz, making it suitable for stable DC biasing in temperature-varying environments while maintaining low signal distortion in analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 6.2 V ±5% - defines precise clamping threshold for overvoltage protection circuits |
| Reverse Leakage Current | 3 µA at VR = 6.2 V - ensures minimal quiescent power loss in always-on monitoring nodes |
| Differential Resistance | 40 Ω typical at IZ = 5 mA - provides tight regulation stability under load variation |
| Forward Voltage | 0.9 V max at IF = 10 mA - enables low-loss anode-side switching in active clamp configurations |
| Total Power Dissipation | 350 mW at Tamb = 25 °C (2 diodes loaded) - supports continuous operation on standard FR4 PCBs |
| Junction Temperature Limit | 150 °C - certified for under-hood automotive electronics per AEC-Q101 |
| Thermal Resistance j-a | 355 K/W (2 diodes loaded, free air) - informs heatsinking requirements for sustained surge duty cycles |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package, 2.0 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | First Zener element cathode - connects to regulated node requiring 6.2 V clamping or reference |
| 2 | K2 (Cathode 2) | Second independent Zener cathode - enables dual-path protection or complementary biasing |
| 3 | CA (Common Anode) | Shared anode terminal - simplifies PCB layout for bidirectional voltage limiting or rail-to-rail clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114 |
| ±5% Zener tolerance | Reduces calibration overhead in factory-trimmed sensor modules and battery management references |
| Low 200 pF capacitance | Minimizes signal integrity impact in high-speed data lines (e.g., CAN FD transceiver I/O protection) |
| 40 W peak surge rating | Withstands ISO 7637-2 Pulse 1 (−150 V, 50 Ω, 2 Ω series) without degradation |
| Common-anode dual-diode topology | Eliminates need for discrete anode tie trace, reducing parasitic inductance in ESD-critical paths |
Applications
| Automotive Sensor Signal Conditioning | Industrial Analog Input Protection |
|---|---|
Use Scenario: Protecting 0–5 V analog outputs of engine coolant temperature sensors against load dump transients. IC Role / Device Role / Timing Role: Dual-Zener clamping device providing bidirectional overvoltage limiting at ADC input stage.

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 |
|---|---|---|---|
| DMN2013LFG-7 | Single-channel 6.2 V Zener, SOT23 package, no common-anode configuration | Requires external anode tie for dual-path use; higher board area and parasitic inductance | Select when only one clamping path is needed and space permits discrete routing |
| BZX84-C6V2,215 | Single Zener, SOT23, ±5% tolerance, 100 nA IR at VR = 6.2 V - lower leakage but no dual-element integration | Lacks integrated dual-cathode structure; needs two devices and extra passives for symmetrical clamping | Prefer for ultra-low standby current designs where dual functionality is implemented discretely |
Compared with DMN2013LFG-7 and BZX84-C6V2,215, the BZB784-C6V2-QX uniquely delivers matched dual-Zener characteristics in one die with shared anode - reducing component count, layout complexity, and thermal mismatch in automotive sensor interface designs.

FAQ
What is the maximum non-repetitive peak reverse current for BZB784-C6V2-QX?
The BZB784-C6V2-QX supports a non-repetitive peak reverse current (IZSM) of 6.0 A under tp = 100 µs square-wave conditions at Tamb = 25 °C, as specified in Table 8 of the datasheet. This rating enables compliance with ISO 7637-2 Pulse 1 and Pulse 2a transient immunity requirements in 12 V automotive systems.
Can BZB784-C6V2-QX be used for bidirectional clamping?
Yes - its common-anode dual-cathode configuration allows direct implementation of bidirectional clamping: connecting CA to ground and K1/K2 to protected nodes enables symmetric ±6.2 V limiting relative to GND, widely applied in CAN bus and LIN transceiver I/O protection.
Is the 6.2 V Zener voltage specified at a particular test current?
Yes - the nominal 6.2 V Zener voltage is characterized at IZ = 5 mA, with ±5% tolerance. The datasheet also specifies differential resistance (rdiff = 40 Ω typ.) and temperature coefficient (+2.2 mV/K) under the same 5 mA condition, ensuring predictable behavior in regulated bias applications.
How does thermal resistance differ between single- and dual-diode operation?
When only one diode is active, Rth(j-a) is 680 K/W; with both diodes loaded, it drops to 355 K/W due to increased heat spreading across the shared die. This 48% reduction must be accounted for in thermal design - dual-diode operation improves power handling but requires derating above Tamb = 70 °C per Figure 6 in the datasheet.
