Product details
Overview
BZX84J-C7V5 from Nexperia is a Zener voltage regulator diode in SOD323F (SC-90) package, designed for precision voltage reference and overvoltage protection in low-power circuits. It delivers a nominal 7.5 V regulation at 5 mA test current, with ±5 % tolerance, 80 Ω differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX84J-C7V5 datasheet, BZX84J-C7V5 pinout, BZX84J-C7V5 application, or BZX84J-C7V5 equivalent, this device is selected for stable low-current biasing, ESD clamp staging, and supply rail monitoring where compact size, thermal robustness, and automotive-grade reliability are required.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its cathode–anode terminals under controlled current conditions. Its regulation accuracy depends on test current (IZ = 5 mA), temperature coefficient (+2.5 mV/K typical), and low dynamic impedance (80 Ω).
The device exhibits non-repetitive surge capability of 40 W (tp = 100 μs, square wave, Tj = 25 °C), total power dissipation limited to 550 mW at Tamb ≤ 25 °C, and junction temperature rating up to 150 °C - enabling reliable operation in thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 7.5 V at IZ = 5 mA - defines primary regulation point for bias/reference circuits |
| Tolerance | ±5 % - sets absolute voltage window (7.00 V to 7.90 V) for design margining |
| Differential Resistance | 80 Ω - determines output voltage variation per 1 mA load change near regulation point |
| Temperature Coefficient | +2.5 mV/K - quantifies drift magnitude per degree Celsius rise in junction temperature |
| Total Power Dissipation | 550 mW at Tamb ≤ 25 °C - establishes maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power | 40 W (tp = 100 μs) - supports transient overvoltage clamping without failure |
| Forward Voltage | 1.1 V at IF = 100 mA - defines conduction threshold and forward loss in series protection configurations |
Pinout & Package
Package: SOD323F (SC-90), surface-mount plastic package with 2 leads, dimensions 2.7 mm × 1.6 mm × 0.95 mm (L × W × H), cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal; reverse-biased during regulation |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics |
| Low differential resistance (80 Ω) | Minimizes output voltage deviation under varying load current in reference circuits |
| SOD323F ultra-small footprint | Enables high-density routing in space-constrained modules like ADAS sensors and infotainment ECUs |
| Wide operating temperature range | −55 °C to +150 °C ambient enables deployment in under-hood and powertrain environments |
| Non-repetitive 40 W surge rating | Provides robust transient suppression against ISO 7637-2 pulse 1/2a/3a without external TVS stacking |
Applications
| Automotive Sensor Biasing | Industrial Analog Input Protection |
|---|---|
|
Use Scenario: Providing stable 7.5 V reference for analog front-end amplifiers in wheel speed or pressure sensors. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, maintaining constant bias point despite supply ripple or load variation. Use Value: Enables <1 % full-scale error in 12-bit ADC conversions under 150 °C junction conditions due to tight tolerance and low rdiff. |
Use Scenario: Clamping input transients on 0–10 V analog sensor lines in PLC I/O modules. IC Role / Device Role / Timing Role: Functions as secondary overvoltage clamp after primary TVS, absorbing residual energy below 40 W peak. Use Value: Prevents op-amp saturation and protects downstream SAR ADC inputs during 100 μs surges per IEC 61000-4-4 Level 3. |
| USB Port ESD Staging | Low-Power MCU Reset Circuit |
|
Use Scenario: Cascaded ESD protection stage between USB data lines and USB transceiver IC. IC Role / Device Role / Timing Role: Zener diode provides low-capacitance (<170 pF) clamping to limit voltage overshoot before fast-response TVS triggers. Use Value: Reduces signal distortion on USB 2.0 D+/D− lines while meeting IEC 61000-4-2 ±8 kV contact discharge requirements. |
Use Scenario: Generating clean reset threshold for 3.3 V microcontrollers using resistor divider + Zener clamp. IC Role / Device Role / Timing Role: Shunt regulator holds reset line at precise 7.5 V until main supply crosses threshold, then releases reset cleanly. Use Value: Eliminates brown-out false triggers in battery-powered IoT nodes by stabilizing reset timing across −40 °C to +85 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5 | Same Zener voltage and tolerance, but not AEC-Q101 qualified; higher rdiff (100 Ω vs. 80 Ω) | Limited to commercial-grade consumer or industrial equipment without automotive qualification requirements | Select when cost sensitivity outweighs automotive compliance and tighter regulation stability |
| MMSZ5236B | 7.5 V ±5 %, SOD-123 package, rdiff = 100 Ω, Ptot = 500 mW, no AEC-Q101 certification | Compatible footprint but larger thermal resistance (Rth(j-a) ≈ 300 K/W vs. 230 K/W), limiting power handling in dense layouts | Choose only if SOD-123 is already standardized in existing designs and derating for thermal margin is acceptable |
Compared with BZX84-C7V5 and MMSZ5236B, the BZX84J-C7V5 offers superior automotive qualification, lower dynamic impedance, and better thermal performance in the smaller SOD323F package - making it the preferred choice for next-generation automotive and high-reliability embedded systems where board space and regulatory compliance are critical.

FAQ
What is the maximum continuous reverse current for stable regulation?
The BZX84J-C7V5 is specified for stable Zener operation at IZ = 5 mA, with maximum continuous reverse current limited by power dissipation: at Tamb = 25 °C, Imax ≈ 73 mA (550 mW ÷ 7.5 V). Operation above this requires thermal derating per Rth(j-a) = 230 K/W and ambient temperature constraints.
Can this Zener be used in series with another diode for higher voltage reference?
Yes - two BZX84J-C7V5 devices in series yield ~15 V reference, but total tolerance becomes ±10 % (root-sum-square not applicable for worst-case), and differential resistance adds linearly (160 Ω). Thermal coupling must be managed to avoid mismatched TC drift; parallel configuration is not recommended due to current-sharing instability.
Is the cathode marking consistent across all BZX84J-Cxx variants?
Yes - all BZX84J-Cxx parts use identical SOD323F packaging with a single bar marking on the top surface indicating Pin 1 (cathode); marking codes vary per voltage (e.g., UU for C7V5), but physical orientation and polarity remain standardized per Nexperia's package outline Fig. 11.
How does the +2.5 mV/K temperature coefficient affect long-term accuracy?
Over a 100 °C junction temperature swing (25 °C to 125 °C), the Zener voltage shifts +250 mV - a +3.3 % deviation from 7.5 V. For precision references, this requires compensation via resistor networks or selection of lower-TC variants (e.g., BZX84J-B7V5 at +0.4 mV/K) where stability dominates over voltage level.
