Product details
Overview
BZX84J-C8V2,115 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 8.2 V nominal Zener voltage at 5 mA test current, ±5 % tolerance, 80 Ω differential resistance, and 550 mW total power dissipation. Used in automotive sensor biasing, MCU reset circuitry, and analog signal conditioning.
For engineers reviewing the BZX84J-C8V2,115 datasheet, BZX84J-C8V2,115 pinout, BZX84J-C8V2,115 application, or BZX84J-C8V2,115 equivalent, key selection criteria include Zener voltage accuracy, thermal stability across -55 °C to +150 °C, AEC-Q101 qualification for automotive use, and low capacitance (150 pF) for high-frequency noise suppression.
Technical Context
This device operates as a two-terminal reverse-biased voltage reference with sharp breakdown knee and low dynamic impedance. Its temperature coefficient of +3.2 mV/K at 5 mA enables predictable drift compensation in stable bias networks.
The SOD323F package provides 230 K/W junction-to-ambient thermal resistance on FR4 PCBs, supporting reliable operation up to 150 °C junction temperature. Non-repetitive peak reverse power dissipation is rated at 40 W for ≥7.5 V types under 100 µs square-wave surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.2 V nominal at IZ = 5 mA; defines precise clamping threshold for regulation and protection |
| Tolerance | ±5 %; ensures predictable voltage window (7.7 V–8.7 V) without binning or calibration |
| Differential Resistance (rdiff) | 80 Ω max at IZ = 5 mA; maintains tight regulation under load current variation |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C; supports continuous operation in compact SMT layouts |
| Reverse Current (IR) | 0.7 µA max at VR = 6.56 V; guarantees minimal leakage in standby or low-power modes |
| Capacitance (Cd) | 150 pF at f = 1 MHz, VR = 0 V; limits high-frequency signal distortion in filtering applications |
| Temperature Coefficient (SZ) | +3.2 mV/K at IZ = 5 mA; enables linear drift modeling for temperature-compensated references |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2.3 mm × 1.35 mm × 0.95 mm body, 0.65 mm lead pitch, 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 for correct PCB orientation |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes reverse-bias path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114 |
| Low differential resistance | 80 Ω max ensures <10 mV output shift per 1 mA load change - critical for stable sensor excitation |
| Wide operating temperature range | -55 °C to +150 °C ambient enables deployment in engine control units and under-hood electronics |
| Precision voltage tolerance | ±5 % eliminates need for post-solder trimming in cost-sensitive consumer and industrial power rails |
| Small SOD323F footprint | 0.65 mm pitch and 2.3 mm × 1.35 mm outline support high-density routing on space-constrained PCBs |
Applications
| Automotive Sensor Biasing | MCU Reset Circuitry |
|---|---|
Use Scenario: Providing stable 8.2 V reference to analog front-end of pressure or temperature sensors in engine management systems. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, maintaining constant bias voltage despite battery fluctuations between 9 V–16 V. Use Value: Enables <±0.5 % sensor output accuracy over full temperature range due to matched thermal coefficient and low rdiff. |
Use Scenario: Generating clean, glitch-free reset signal for microcontrollers during power-up and brown-out events. IC Role / Device Role / Timing Role: Functions as voltage supervisor element in RC-based reset generator, clamping capacitor voltage at 8.2 V until threshold is reached. Use Value: Guarantees deterministic reset assertion time with <5 % variation across production lots and temperature extremes. |
| Industrial Analog Signal Conditioning | USB Port Overvoltage Protection |
Use Scenario: Stabilizing reference voltage for op-amp gain-setting resistors in 4–20 mA transmitter circuits. IC Role / Device Role / Timing Role: Shunt regulator establishes fixed reference point for current loop scaling, rejecting supply ripple above 10 kHz. Use Value: Reduces output error to <0.1 % FS by limiting reference drift to <±2 mV over -40 °C to +85 °C. |
Use Scenario: Clamping transient surges on USB VBUS line caused by hot-plug inductive kick or ESD events. IC Role / Device Role / Timing Role: Fast-acting Zener clamp diverts >40 W surge energy (100 µs pulse) away from downstream USB controller ICs. Use Value: Survives 1000+ ESD strikes per IEC 61000-4-2 Level 4 without parameter shift or failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2,115 | Same Zener voltage and package, but ±5 % tolerance only; lacks AEC-Q101 qualification and higher IZSM rating | Restricted to commercial-grade applications; not suitable for automotive or extended-temperature industrial use | Select when AEC-Q101 compliance and 150 °C operation are unnecessary and cost is primary driver |
| MMSZ4687T1G | 8.2 V, ±5 %, SOD-123 package; 500 mW Ptot, 100 Ω rdiff, no AEC-Q101 certification | Larger footprint (3.7 mm × 1.6 mm); higher thermal resistance limits sustained power handling | Choose only if board layout accommodates larger package and automotive qualification is not required |
Compared with BZX84J-C8V2,115, the BZX84-C8V2,115 sacrifices automotive reliability for lower unit cost, while MMSZ4687T1G trades package size and thermal performance for broader distributor availability - neither matches the combination of AEC-Q101, 80 Ω rdiff, and SOD323F miniaturization.

FAQ
What is the maximum non-repetitive peak reverse power dissipation for BZX84J-C8V2,115?
The device is rated for 40 W non-repetitive peak reverse power dissipation under pulsed conditions (tp = 100 µs, square wave, Tj = 25 °C prior to surge), consistent with its ≥7.5 V Zener voltage classification per Table 5 and Figure 1.
How does the temperature coefficient affect regulation accuracy over temperature?
With a specified +3.2 mV/K temperature coefficient at 5 mA, the Zener voltage increases by approximately 32 mV over a 10 °C rise - enabling predictable drift compensation in bias networks where reference stability is critical.
Is BZX84J-C8V2,115 suitable for use in reflow soldering processes?
Yes - the SOD323F package is qualified for standard lead-free reflow soldering per JEDEC J-STD-020, with peak temperatures up to 260 °C; Figure 12 provides the recommended solder land pattern for optimal thermal and mechanical reliability.
What is the forward voltage drop at 100 mA DC current?
The forward voltage is guaranteed ≤1.1 V at IF = 100 mA (pulsed, tp ≤ 300 µs, δ ≤ 0.02), as specified in Table 1 - confirming suitability for dual-role applications requiring both Zener regulation and low-loss forward conduction.
