Product details
Overview
BZX884-B8V2,315 from Nexperia is a ±2 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 8.2 V nominal regulation at 5 mA, with 250 mW total power dissipation and 20 Ω typical differential resistance at IZ = 5 mA. It serves as a precision voltage reference or clamp in low-power analog circuits, ESD protection paths, and high-frequency signal conditioning stages.
For engineers reviewing the BZX884-B8V2,315 datasheet, BZX884-B8V2,315 pinout, BZX884-B8V2,315 application, or BZX884-B8V2,315 equivalent, this page delivers verified Zener voltage, thermal resistance, reverse leakage, capacitance, and AEC-Q101 qualification status - all critical for automotive-grade voltage stabilization and transient suppression design.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 8.2 V (min 8.04 V, max 8.36 V) at IZ = 5 mA and exhibits a positive temperature coefficient of +4.3 mV/K at that current. Its low 150 pF capacitance at f = 1 MHz and VR = 0 V enables stable performance in RF and fast-switching applications.
The device features ultra-small DFN1006-2 packaging with 1.0 × 0.6 × 0.5 mm body dimensions and a marking bar indicating the cathode terminal. It is qualified to AEC-Q101 for automotive use and supports operation across −55 °C to +150 °C ambient temperature range.

Use Scenario: Providing stable 8.2 V reference for analog front-end amplifiers in engine control unit (ECU) temperature sensors. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage regulator, maintaining constant bias point despite battery voltage fluctuations (9–16 V). Use Value: Ensures <±1% output accuracy over −40 °C to +125 °C, meeting ASIL-B functional safety requirements for sensor signal conditioning. |
Use Scenario: Placed between USB D+ line and ground to suppress fast ESD transients per IEC 61000-4-2 Level 4 (±15 kV contact). IC Role / Device Role / Timing Role: Functions as ultra-fast clamping diode, diverting surge current before IC input structures are damaged. Use Value: 4 A non-repetitive peak current rating and 150 pF capacitance prevent signal degradation while passing USB 2.0 data rates (480 Mbps). |
| Industrial PLC Analog Input | High-Frequency Oscillator Stabilization |
|
Use Scenario: Protecting 0–10 V analog input channels in programmable logic controllers from overvoltage events. IC Role / Device Role / Timing Role: Acts as precision overvoltage clamp, limiting input to 8.2 V ±2 % to safeguard ADC front-end op-amps. Use Value: 20 Ω dynamic impedance ensures clamp voltage remains within 50 mV of nominal during 100 mA surge, preventing latch-up. |
Use Scenario: Stabilizing tuning voltage in VCO-based RF synthesizers operating above 1 GHz. IC Role / Device Role / Timing Role: Supplies low-noise, low-capacitance reference to varactor diodes in phase-locked loop (PLL) feedback paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-C8V2,315 | ±5 % tolerance (7.79–8.61 V), higher max leakage (1 µA at 5 V) | Acceptable where cost sensitivity outweighs regulation precision | Select when budget constraints dominate and ±5 % voltage error is acceptable in non-critical biasing |
| MMSZ4689T1G | Same 8.2 V nominal, ±5 % tolerance, SOD-123 package (1.8 × 1.4 × 1.0 mm) | Larger footprint limits high-density routing; lacks AEC-Q101 qualification | Choose only for non-automotive prototypes requiring legacy footprint compatibility |
Compared with BZX884-C8V2,315 and MMSZ4689T1G, the BZX884-B8V2,315 delivers tighter voltage control, automotive qualification, and superior high-frequency response - making it optimal for safety-critical and miniaturized designs where regulation stability and ESD immunity are co-dependent requirements.

FAQ
What is the maximum reverse current at 5 V for BZX884-B8V2,315?
The maximum reverse leakage current is 700 nA at VR = 5 V and Tj = 25 °C, as specified in Table 7 of the official Nexperia datasheet Rev. 5. This value increases with junction temperature but remains below 1 µA up to 125 °C, supporting low-power standby operation.
Is BZX884-B8V2,315 suitable for reflow soldering?
Yes - the SOD882 package is qualified for lead-free reflow soldering per J-STD-020. The recommended profile uses peak temperatures up to 260 °C for ≤30 seconds, with preheat ramp rates of 1–3 °C/s. Figure 12 in the datasheet provides the exact solder land pattern and stencil design.
How does the temperature coefficient affect regulation accuracy?
With a typical +4.3 mV/K coefficient at IZ = 5 mA, the Zener voltage increases by ~0.43 V over a 100 °C junction temperature rise. For applications requiring stable output across wide temperature ranges, this drift must be compensated in system-level calibration or mitigated via thermal management.
Can BZX884-B8V2,315 replace BZX84-B8V2 in existing designs?
No - BZX84-B8V2 uses SOT-23 packaging (3.0 × 1.4 × 1.1 mm), while BZX884-B8V2,315 uses SOD882 (1.0 × 0.6 × 0.5 mm). The footprint, thermal behavior, and mounting process differ significantly; direct replacement requires PCB redesign and requalification per AEC-Q101.
