Product details
Overview
BZX884-B4V7,315 from Nexperia is a ±2% tolerance Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation and ESD protection at 4.7 V nominal Zener voltage with 50 Ω typical differential resistance at 5 mA and −1.2 mV/K temperature coefficient. It delivers stable clamping in low-power analog rails, I/O line protection, and high-frequency bias networks.
For engineers reviewing the BZX884-B4V7,315 datasheet, BZX884-B4V7,315 pinout, BZX884-B4V7,315 application, or BZX884-B4V7,315 equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at operating current, thermal coefficient, reverse leakage at specified VR, and ultra-small SMD footprint compatibility with automated assembly.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 4.7 V at 5 mA test current, exhibiting tight ±2% initial tolerance and low temperature drift (−1.2 mV/K). Its construction enables fast response to transient overvoltage events, supporting ESD protection per IEC 61000-4-2 Level 4 when used with appropriate series impedance.
The device features a maximum forward voltage of 0.9 V at 10 mA and reverse leakage limited to 3 µA at VR = 2 V, ensuring minimal standby power loss and clean clamping thresholds. Thermal resistance from junction to ambient is 500 K/W under standard FR4 mounting conditions, defining its derating behavior in compact layouts.
Key Specifications

Applications
| Power Supply Rail Clamping | I/O Line ESD Protection |
|---|---|
Use Scenario: Clamping 3.3 V or 5 V microcontroller supply rails against inductive switching spikes and hot-swap transients. IC Role / Device Role / Timing Role: Zener diode acts as shunt regulator and overvoltage clamp, conducting only when rail exceeds 4.7 V. Use Value: Prevents latch-up and damage to downstream logic by limiting peak voltage to ≤5.0 V with <100 ns response. | Use Scenario: Protecting UART, I²C, or GPIO pins from electrostatic discharge events up to ±15 kV contact discharge. IC Role / Device Role / Timing Role: Passive ESD clamp placed between signal line and ground, triggered by fast-rising transients. Use Value: Limits pin voltage to safe levels (<6 V) while maintaining signal integrity due to low capacitance (320 pF). |
| Reference Voltage Source | High-Frequency Bias Network |
Use Scenario: Providing stable 4.7 V bias for op-amp input stages, ADC reference dividers, or sensor excitation circuits. IC Role / Device Role / Timing Role: Precision Zener used as two-terminal voltage reference with buffered output. Use Value: Delivers ±2% initial accuracy and −1.2 mV/K drift, enabling sub-0.5% total error over −40 °C to +125 °C. | Use Scenario: Establishing DC bias points in RF amplifier matching networks and broadband filter tuning circuits. IC Role / Device Role / Timing Role: Low-capacitance (320 pF) Zener stabilizes DC operating point without degrading AC signal path. Use Value: Maintains impedance stability above 10 MHz due to minimal parasitic capacitance and fast recovery. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-C4V7,315 | ±5% tolerance vs. ±2%; higher rdiff (80 Ω typ); same VZ range and package | Acceptable where cost sensitivity outweighs precision; less suitable for temperature-critical references | Select for non-critical biasing where tighter tolerance is unnecessary and BOM cost reduction is prioritized |
| MMSZ4702T1G | ±5% tolerance; SOD-123 package (2.7 × 1.4 × 1.0 mm); 500 mW Ptot; 70 Ω rdiff typ | Higher power handling but 3× larger footprint; not AEC-Q101 qualified | Choose when board space permits and automotive qualification is not required, especially for higher-energy transients |
Compared with BZX884-C4V7,315, the BZX884-B4V7,315 offers tighter voltage control and lower impedance for precision analog use; versus MMSZ4702T1G, it trades power capacity for miniaturization and automotive compliance-critical for ADAS and body electronics.

FAQ
What is the maximum reverse current specification for BZX884-B4V7,315 at 2 V?
The maximum reverse leakage current (IR) is 3 µA at VR = 2 V and Tj = 25 °C. This low leakage ensures minimal loading on high-impedance nodes such as sensor outputs or reference dividers, preserving signal fidelity and reducing standby power consumption in battery-powered systems.
Is BZX884-B4V7,315 suitable for automotive applications?
Yes, BZX884-B4V7,315 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, high-temperature reverse bias, and ESD robustness required for automotive electronics. It is deployed in engine control units, body control modules, and infotainment systems where reliability under harsh environmental conditions is mandatory.
How does the SOD882 package affect thermal performance?
The SOD882 package has a junction-to-ambient thermal resistance (Rth(j-a)) of 500 K/W under standard FR4 mounting. This means power dissipation must be derated above 25 °C ambient-e.g., only ~125 mW is sustainable at 75 °C ambient-making it ideal for low-duty-cycle clamping rather than continuous regulation.
What is the typical Zener capacitance of BZX884-B4V7,315?
The typical diode capacitance (Cd) is 320 pF at f = 1 MHz and VR = 0 V. This value supports high-frequency applications such as RF bias networks and fast digital I/O protection, where excessive capacitance would distort signal edges or degrade bandwidth.
