Product details
Overview
BZX84J-C5V1,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323F (SC-90) package, providing 5.1 V nominal regulation at 5 mA test current, with 480 Ω typical differential resistance and 2 µA maximum reverse leakage at 3.8 V. It delivers stable reference voltage for low-power biasing and overvoltage clamping in automotive body electronics and industrial sensor interfaces.
For engineers reviewing the BZX84J-C5V1,115 datasheet, BZX84J-C5V1,115 pinout, BZX84J-C5V1,115 application, or BZX84J-C5V1,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (230 K/W junction-to-ambient), AEC-Q101 qualification, non-repetitive surge capability (12 A peak reverse current), and SOD323F footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 5.1 V reference across load and supply variations. Its 480 Ω differential resistance ensures minimal voltage shift under ±1 mA current change at 5 mA bias, while the −2.7 to +1.2 mV/K temperature coefficient enables predictable drift behavior from 25 °C to 150 °C junction temperature.
Designed for surface-mount reliability, it supports pulsed surge handling up to 40 W (100 µs square wave, Tj = 25 °C prior to surge) and continuous dissipation of 550 mW on FR4 PCB with 1 cm² cathode pad. The AEC-Q101 qualification confirms suitability for automotive ambient temperature ranges (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.80 V to 5.40 V at IZ = 5 mA - defines regulation window for precision biasing |
| Differential Resistance (rdiff) | 480 Ω typical - determines output impedance and load regulation sensitivity |
| Reverse Leakage (IR) | 2 µA max at VR = 3.8 V - limits quiescent current in standby circuits |
| Non-repetitive Peak Current (IZSM) | 12 A at tp = 100 µs - enables transient overvoltage suppression without failure |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - sets continuous thermal limit on standard FR4 board |
| Thermal Resistance (Rth(j-a)) | 230 K/W - quantifies junction-to-ambient heat transfer efficiency on single-sided copper |
| Temperature Coefficient (SZ) | −2.7 to +1.2 mV/K - specifies voltage drift per degree over operating junction range |
Pinout & Package
The BZX84J-C5V1,115 is housed in a SOD323F (SC-90) plastic surface-mount package measuring 2.7 mm × 1.6 mm × 0.95 mm, with gull-wing leads and cathode marked by a bar on the 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; reverse-biased configuration enables Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and lighting systems |
| Low differential resistance | 480 Ω typical ensures <1 mV output shift per 2 µA load variation at 5 mA bias |
| Small SOD323F footprint | 2.7 mm × 1.6 mm area supports high-density routing in space-constrained ECUs and sensors |
| Wide surge capability | 40 W non-repetitive peak power (≥7.5 V types) handles ESD and load-dump transients |
| Two tolerance options | ±5 % (C-series) balances cost and accuracy for general-purpose regulation tasks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1,115 | Same Zener voltage and tolerance, but not AEC-Q101 qualified; higher rdiff (500 Ω typ) | Limited to commercial-grade consumer electronics, not automotive or industrial harsh environments | Select when AEC-Q101 compliance is unnecessary and cost is primary driver |
| MMSZ5231B-7-F | 5.1 V ±5 %, SOD-123 package (larger), 600 mW Ptot, 170 Ω rdiff, no AEC-Q101 | Better regulation accuracy but incompatible SOD-123 footprint; unsuitable for ultra-compact layouts | Choose only if board redesign allows larger package and tighter regulation is critical |
Compared with BZX84J-C5V1,115, the BZX84-C5V1,115 lacks automotive qualification and has higher dynamic impedance, while MMSZ5231B-7-F offers lower rdiff but requires layout revision and forfeits AEC-Q101 assurance-making the J-series optimal for space-constrained, automotive-grade designs requiring proven reliability.

FAQ
What is the maximum continuous power dissipation for BZX84J-C5V1,115?
The BZX84J-C5V1,115 has a total power dissipation limit of 550 mW at ambient temperature ≤25 °C when mounted on an FR4 PCB with a 1 cm² cathode pad. Derating is required above 25 °C at 4.4 mW/°C based on its 230 K/W junction-to-ambient thermal resistance.
Is BZX84J-C5V1,115 suitable for automotive applications?
Yes-this device is fully qualified to AEC-Q101 standards, with guaranteed operation from −55 °C to +150 °C junction temperature and validated reliability for automotive body electronics, lighting, and infotainment systems where stable voltage reference is critical.
How does the temperature coefficient affect regulation accuracy?
At 5.1 V nominal, the BZX84J-C5V1,115 exhibits a temperature coefficient between −2.7 mV/K and +1.2 mV/K. Over a 125 °C junction range (25 °C to 150 °C), this results in up to ±125 mV total drift-within acceptable bounds for non-precision biasing and clamping functions.
What is the meaning of the 'C' in BZX84J-C5V1,115?
The 'C' denotes ±5 % Zener voltage tolerance at IZ = 5 mA, distinguishing it from 'B'-series parts with ±2 % tolerance. This grade balances cost-effectiveness and performance for general-purpose regulation where tight voltage accuracy is not mandatory.
