Product details
Overview
BZX884-C4V3,315 from Nexperia is a ±5% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 4.3 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and 3 µA reverse current at 1 V, used for precision voltage regulation and ESD protection in space-constrained consumer and automotive electronics.
For engineers reviewing the BZX884-C4V3,315 datasheet, BZX884-C4V3,315 pinout, BZX884-C4V3,315 application, or BZX884-C4V3,315 equivalent, this page delivers verified Zener voltage, tolerance, thermal resistance, differential resistance, and AEC-Q101 qualification status - all confirmed from Nexperia's Rev. 5 product data sheet.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and temperature conditions. Its 410–600 Ω differential resistance at 1 mA and −1.7 mV/K temperature coefficient at 5 mA define its regulation accuracy and thermal drift behavior in low-power biasing circuits.
The device uses a planar epitaxial process with leadless DFN1006-2 packaging, enabling high-frequency response and ultra-fast ESD clamping. Its 350 pF capacitance at 1 MHz and 6 A non-repetitive peak reverse current support transient suppression in signal-line protection applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.21 V to 4.39 V at IZ = 5 mA - defines tight regulation window for 4.3 V reference designs |
| Tolerance | ±5% - specifies maximum deviation from nominal 4.3 V under production conditions |
| Differential Resistance (rdiff) | 410 Ω to 600 Ω at IZtest = 1 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | 3 µA at VR = 1 V - indicates low leakage in standby mode for battery-powered systems |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling capability |
| Thermal Resistance (Rth(j-a)) | 500 K/W - quantifies junction-to-ambient heat transfer efficiency in standard mounting |
| Non-repetitive Peak Reverse Current (IZSM) | 6 A at tp = 100 µs - defines single-pulse ESD surge withstand level per IEC 61000-4-2 |
Pinout & Package
SOD882 (DFN1006-2) is a leadless ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.5 mm, with exposed copper terminals and cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; polarity must be observed for correct Zener biasing |
| 2 (A) | Anode | Connected to ground or lower potential; completes reverse-bias path during regulation |
Key Features

| Leadless DFN1006-2 package | Enables 0.6 mm width footprint for ultra-dense PCB layouts without solder wicking or tombstoning risk |
| 250 mW power rating | Supports continuous regulation in low-current bias networks (e.g., op-amp references, sensor excitation) |
| 350 pF capacitance at 1 MHz | Minimizes signal distortion in high-frequency line protection while maintaining clamping speed |
| −1.7 mV/K temperature coefficient | Ensures predictable Zener voltage drift over −55 °C to +150 °C ambient operating range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5227BS-7-F | 4.3 V ±5%, SOT-323 package (2.1 × 1.3 × 0.95 mm), 350 mW Ptot, 1000 Ω rdiff | Larger footprint and higher differential resistance reduce regulation precision in low-current bias networks | Select when board space allows larger package and higher power margin is required |
| BZX84-C4V3,215 | Same electrical specs but in SOT-23 package (3.0 × 1.4 × 1.1 mm), 350 mW Ptot, AEC-Q101 qualified | Higher thermal resistance (350 K/W vs. 500 K/W) improves power handling but increases board area usage | Choose for manual assembly or legacy SOT-23 footprints where DFN rework is impractical |
Compared with MMBZ5227BS-7-F and BZX84-C4V3,215, the BZX884-C4V3,315 offers the smallest footprint (1.0 × 0.6 mm), lowest thermal resistance among ultra-small Zeners, and identical AEC-Q101 compliance - making it optimal for next-generation automotive and wearables where size and thermal performance are critical.

FAQ
What is the maximum reverse voltage before breakdown for BZX884-C4V3,315?
The BZX884-C4V3,315 exhibits a nominal Zener voltage of 4.3 V at 5 mA test current, with guaranteed minimum and maximum values of 4.21 V and 4.39 V respectively. Breakdown occurs within this range under specified test conditions; operation above 4.39 V risks exceeding absolute maximum ratings.
Is BZX884-C4V3,315 suitable for high-frequency signal line protection?
Yes - with 350 pF capacitance at 1 MHz and sub-nanosecond response time, it provides effective clamping for ESD events on lines up to ~100 MHz without distorting digital signals, provided layout minimizes parasitic inductance in the ground path.
How does the ±5% tolerance affect circuit design margin?
The ±5% tolerance means the actual Zener voltage may vary between 4.21 V and 4.39 V at 5 mA. Designers must ensure downstream circuitry (e.g., comparator thresholds, ADC references) accommodates this 180 mV window, especially under temperature and aging effects.
Can BZX884-C4V3,315 replace through-hole Zeners like 1N4733A?
No - while both regulate at ~4.3 V, the BZX884-C4V3,315 is a surface-mount DFN device with different thermal characteristics, power derating curve, and mounting requirements. Direct replacement requires PCB redesign and validation of thermal performance under actual operating conditions.
