Product details
Overview
BZX884-B11,315 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD882 (DFN1006-2) package, rated for 11 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and 150 °C maximum junction temperature. It serves as a precision voltage reference or clamp in low-power analog signal conditioning, ESD protection circuits, and high-frequency bias networks.
For engineers reviewing the BZX884-B11,315 datasheet, BZX884-B11,315 pinout, BZX884-B11,315 application, or BZX884-B11,315 equivalent, this page delivers verified electrical parameters, thermal behavior, AEC-Q101 qualification status, and surface-mount layout guidance specific to the 11 V ±2 % variant in ultra-small DFN1006-2 packaging.
Technical Context
This Zener diode operates in reverse breakdown with a typical differential resistance of 25 Ω at 5 mA test current and exhibits a positive temperature coefficient of +6.9 mV/K at the same condition. Its low 110 pF capacitance at 0 V reverse bias supports stable performance up to high-frequency switching applications.
The device is qualified to AEC-Q101 for automotive use and features a non-repetitive peak reverse current rating of 2.5 A under 100 µs square-wave surge conditions at 25 °C ambient. Thermal resistance from junction-to-ambient is 500 K/W on standard FR4 PCB with single-sided copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.78 V to 11.22 V at IZ = 5 mA - tight ±2 % tolerance enables accurate voltage clamping in precision references |
| Differential Resistance (rdiff) | 25 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load current changes |
| Temperature Coefficient (SZ) | +6.9 mV/K at IZ = 5 mA - predictable positive drift allows compensation in temperature-sensitive circuits |
| Reverse Current (IR) | 100 nA max at VR = 8 V - low leakage preserves accuracy in high-impedance bias networks |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines conduction threshold in series protection configurations |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets thermal derating limit for continuous operation on standard PCB |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports extended industrial and automotive ambient operating ranges |
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 a cathode-marking bar on the top surface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5240BS | 10 V nominal, ±5 % tolerance, SOT-323 package, 225 mW Ptot | Higher voltage drift (+3.5 mV/K), larger footprint, lower surge rating (1.5 A) | Select when cost sensitivity outweighs precision and automotive qualification requirements |
| Vishay BZX84-C11 | 11 V nominal, ±5 % tolerance, SOT-23 package, 300 mW Ptot, no AEC-Q101 | Looser tolerance, higher power, larger thermal resistance (350 K/W), unqualified for automotive | Prefer for non-automotive consumer designs needing higher power margin and legacy SOT-23 compatibility |
Compared with BZX884-B11,315, MMBZ5240BS trades precision and qualification for cost, while BZX84-C11 offers higher power but sacrifices automotive reliability and board-space efficiency-making the BZX884-B11,315 optimal for space-constrained, temperature-stable, and automotive-compliant Zener applications.

FAQ
What is the maximum reverse voltage that BZX884-B11,315 can safely clamp?
The BZX884-B11,315 is rated for a nominal Zener voltage of 10.78 V to 11.22 V at 5 mA, with a maximum non-repetitive peak reverse voltage defined by its surge capability: it withstands 2.5 A for 100 µs at 25 °C ambient. Continuous reverse operation must remain within the 11.22 V upper limit and 250 mW power envelope to avoid thermal runaway.
How does the ±2 % tolerance affect circuit accuracy compared to ±5 % Zeners?
The ±2 % tolerance (B-series) reduces worst-case Zener voltage spread from ±5 % (e.g., 10.45–11.55 V) to ±2 % (10.78–11.22 V) at 5 mA, cutting absolute error from ±0.55 V to ±0.22 V. This directly improves reference stability in analog sensor interfaces and reduces calibration effort in production test flows.
Can BZX884-B11,315 be used in place of a 12 V Zener diode?
No-BZX884-B11,315 is strictly a nominal 11 V device (10.78–11.22 V range). Substituting it for a 12 V Zener would result in ~1 V lower clamping voltage, potentially causing undervoltage faults in circuits designed for 12 V regulation or protection thresholds. Use BZX884-B12,315 for 12 V applications.
Is reflow soldering the only recommended assembly method for this DFN1006-2 package?
Yes-the datasheet explicitly states "Reflow soldering is the only recommended soldering method" for SOD882. Hand soldering risks thermal damage due to the small thermal mass and leadless construction; stencil-printed solder paste with controlled reflow profile (per JEDEC J-STD-020) ensures reliable interconnect and prevents voiding or tombstoning.
