Product details
Overview
BZX884S-C56-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in compact automotive and industrial circuits. It delivers a nominal 56 V Zener voltage with ±5 % tolerance, 100 Ω typical differential resistance at IZ = 2 mA, and operates up to 150 °C junction temperature in the DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-C56-QYL datasheet, BZX884S-C56-QYL pinout, BZX884S-C56-QYL application, or BZX884S-C56-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flank package for automated optical inspection, low 0.9 V forward voltage at 10 mA, and stable temperature coefficient of +70 mV/K at 56 V.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 56 V reference across load variations and supply fluctuations. Its design supports low-current regulation (IZ = 2 mA typical test condition) and exhibits a positive temperature coefficient (+70 mV/K), enabling predictable drift compensation in thermal-aware designs.
The device uses silicon planar epitaxial construction and is optimized for surface-mount applications requiring high reliability under automotive-grade stress conditions. Its ultra-small DFN1006BD-2 footprint (1.0 mm × 0.6 mm × 0.47 mm) and side-wettable flanks ensure robust reflow solder joint inspection and mechanical stability on FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B56-Q | ±2 % tolerance (vs. ±5 %), higher test current (5 mA), tighter VZ spread (54.9–57.1 V) | Preferred where precision reference stability outweighs cost sensitivity; requires recalibration of tolerance-dependent thresholds | Select for metrology-grade references or closed-loop feedback nodes demanding <1 % error budget |
| MMSZ5256B-TP | SOD-123 package (larger), 500 mW Ptot, ±5 %, 110 Ω rdif at 20 mA | Higher power handling but lacks AEC-Q101 qualification and SWF; suited for non-automotive industrial use only | Choose when board-level rework accessibility or legacy footprint compatibility is prioritized over miniaturization |
Compared with BZX884S-C56-QYL, the BZX884S-B56-Q offers tighter regulation at higher test current but increases BOM cost, while MMSZ5256B-TP trades automotive qualification and AOI capability for higher power margin and broader industry familiarity.

FAQ
What is the maximum continuous reverse current this diode can handle before degradation?
The absolute maximum limiting value for forward current is 200 mA, but for Zener operation, the device is rated for continuous reverse current up to 6.5 mA at 56 V (derived from Ptot = 365 mW ÷ VZ). Exceeding this sustained current without thermal derating risks junction overheating beyond 150 °C, accelerating parametric shift and eventual failure.
Does the side-wettable flank feature require special stencil or reflow profile adjustments?
No special stencil design is needed-the standard SOD882BD footprint (1.3 mm × 0.8 mm solder land, 0.4 mm paste opening) specified in Figure 11 supports full wetting. Reflow must follow JEDEC J-STD-020 moisture sensitivity level 1 profile; peak temperature ≤ 260 °C ensures proper solder flow onto flanks without delamination.
How does the +70 mV/K temperature coefficient impact accuracy in a 0–70 °C ambient range?
Over a 70 °C span, the Zener voltage shifts +4.9 V (70 mV/K × 70 K), resulting in ~8.8 % deviation from nominal 56 V. This is inherent to the 56 V Zener physics; system-level compensation-such as pairing with a negative-TC component or digital calibration-is required for sub-1 % total error across temperature.
Can this diode be used in series or parallel configurations for higher voltage or current handling?
Series connection is viable for higher voltage clamping (e.g., two 56 V units for ~112 V), provided matched units are selected to avoid voltage imbalance. Parallel use is not recommended due to VZ tolerance spread and thermal runaway risk-differential resistance mismatch causes current hogging even with ±5 % parts.
