Product details
Overview
BZX84J-C2V7,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323F (SC-90) package, rated for 2.7 V nominal Zener voltage at 5 mA, 550 mW total power dissipation, and AEC-Q101 qualified for automotive use. It provides stable reference voltage in low-power biasing, overvoltage clamping, and supply rail regulation circuits.
For engineers reviewing the BZX84J-C2V7,115 datasheet, BZX84J-C2V7,115 pinout, BZX84J-C2V7,115 application, or BZX84J-C2V7,115 equivalent, key selection criteria include Zener voltage tolerance, differential resistance, non-repetitive surge capability, thermal resistance, and automotive qualification status.
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 2.7 V nominal Zener voltage is specified at IZ = 5 mA with ±5 % tolerance and 450 Ω typical differential resistance.
It features low thermal resistance (Rth(j-a) = 230 K/W on FR4), AEC-Q101 qualification, and pulsed non-repetitive peak reverse power dissipation of 100 W (tp ≤ 300 μs, δ ≤ 0.02) - consistent with ≤6.8 V Zener types per Nexperia's classification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal at IZ = 5 mA; ±5 % tolerance ensures predictable clamping within 2.55–2.85 V range |
| Differential Resistance (rdiff) | 450 Ω max at IZ = 5 mA; defines voltage regulation stiffness under load variation |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C on FR4 PCB; sets maximum continuous DC or average power handling |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA; relevant for polarity-sensitive protection or series bias configurations |
| Non-repetitive Peak Power (PZSM) | 100 W for tp ≤ 300 μs, δ ≤ 0.02; enables transient overvoltage suppression without failure |
| Reverse Current (IR) | 100 µA max at VR = 1 V; confirms low leakage below breakdown threshold |
| Temperature Coefficient (SZ) | −3.5 to 0 mV/K at IZ = 5 mA; indicates negative drift, critical for temperature-stable references |
Pinout & Package
The BZX84J-C2V7,115 is housed in a SOD323F (SC-90) surface-mount plastic package: 2-pin, ultra-small outline (2.3 × 1.35 mm footprint), flat lead, cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; carries reverse current during Zener operation |
| 2 | Anode (A) | Connected to reference ground or lower-potential rail; completes reverse-biased path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| Low differential resistance | 450 Ω max ensures minimal voltage shift under ±1 mA current variation - critical for precision biasing |
| High surge capability | 100 W non-repetitive peak power (≤300 μs) enables reliable transient suppression in noisy environments |
| Small SOD323F package | 0.65 mm profile and 2.3 × 1.35 mm footprint supports high-density PCB layouts in space-constrained modules |
| Wide Zener voltage range | Part of 74-type series spanning 2.4 V to 75 V - allows standardized design reuse across multiple rail voltages |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C2V7,115 | Same Zener voltage and package, but ±5 % tolerance and non-AEC-Q101 qualified; rdiff = 500 Ω max | Not suitable for automotive or mission-critical industrial use due to lack of stress qualification | Select only for cost-sensitive consumer applications where AEC-Q101 is not required |
| MMSZ4678T1G | 2.7 V Zener, ±5 %, SOD-123 package (larger footprint); Ptot = 500 mW; rdiff = 100 Ω typical | Higher power density not needed; larger size limits layout flexibility in miniaturized designs | Prefer when existing SOD-123 land pattern exists and lower rdiff justifies footprint trade-off |
Compared with BZX84J-C2V7,115, the BZX84-C2V7,115 lacks automotive qualification and has higher differential resistance, while MMSZ4678T1G offers tighter regulation but requires board rework for package compatibility - making the J-series optimal for new AEC-Q101-compliant, space-constrained designs.

FAQ
What is the maximum continuous forward current for BZX84J-C2V7,115?
The absolute maximum forward current is 250 mA per limiting values table. However, sustained forward conduction is not intended in Zener regulation applications; the device is optimized for reverse-bias operation. Forward voltage is specified at 100 mA (1.1 V max), and operation above 100 mA should be limited to brief pulses to avoid thermal overstress.
Is BZX84J-C2V7,115 suitable for use in a 125 °C ambient environment?
No - the maximum ambient temperature rating is +150 °C only when derated per thermal characteristics. At 125 °C ambient, total power dissipation must be reduced to ≤170 mW (using Rth(j-a) = 230 K/W) to maintain junction temperature ≤150 °C. Full 550 mW rating applies only at Tamb ≤ 25 °C on specified FR4 PCB.
How does the −3.5 to 0 mV/K temperature coefficient affect circuit performance?
This negative coefficient means the Zener voltage decreases with rising temperature - e.g., ~8 mV drop over 0–85 °C. In precision references, this drift must be compensated via circuit topology (e.g., combining with positive-TC components) or selected only where system-level drift budget permits. It is typical for low-voltage Zeners (<5 V) due to dominant avalanche vs. Zener mechanisms.
Can BZX84J-C2V7,115 replace BZX84-C2V7 in an existing design?
Yes, electrically and physically - same SOD323F package, identical marking (U4), and matching 2.7 V/±5 % specs. The key upgrade is AEC-Q101 qualification and improved surge rating (100 W vs. 40 W for ≥7.5 V types; confirmed 100 W for ≤6.8 V types including this part). No layout or schematic changes are needed for drop-in automotive qualification enhancement.
