Product details
Overview
BZX884S-C47-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 47 V Zener voltage with ±5 % tolerance, 85 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-C47-QYL datasheet, BZX884S-C47-QYL pinout, BZX884S-C47-QYL application, or BZX884S-C47-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, 365 mW power dissipation on FR4, and low 0.9 V forward voltage at 10 mA - critical for low-power biasing and clamping in space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation under varying load and temperature conditions. Its temperature coefficient of +50 mV/K at IZ = 2 mA enables predictable drift compensation in mid-voltage rails, while its 40 pF capacitance at 1 MHz supports high-frequency transient suppression without signal distortion.
The device uses a planar epitaxial silicon structure optimized for low leakage and tight parametric distribution across the E24 voltage range (2.4 V–75 V). Its SOD882BD package features side-wettable flanks to ensure solder joint integrity verification via AOI, meeting automotive reflow process requirements per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 44.0 V to 50.0 V at IZ = 2 mA - defines regulated output voltage window for 47 V nominal rail stabilization |
| Differential Resistance (rdif) | 85 Ω typical at IZ = 2 mA - determines regulation stiffness and load-induced voltage deviation |
| Temperature Coefficient (SZ) | +50 mV/K at IZ = 2 mA - quantifies voltage drift per degree Celsius for thermal design margining |
| Reverse Current (IR) | 0.05 μA max at VR = 35.2 V - ensures minimal standby power loss in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB with 70 μm copper - sets maximum continuous DC or pulsed power handling in standard layout |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - enables low-loss anode-cathode conduction during forward-biased fault conditions |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive and industrial ambient environments |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), leadless ultra-small plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks and 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated voltage node; marked by bar on top surface; reverse-biased terminal during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential reference; unmarked terminal; forward conduction path during overvoltage clamp events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, and HAST testing - suitable for engine control, body electronics, and ADAS power rails |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on both top and side surfaces - eliminates X-ray requirement for production line quality assurance |
| ±5 % Zener tolerance | Tighter than generic Zeners; reduces need for post-production trimming in 47 V reference circuits for sensor excitation or ADC reference buffers |
| Low 40 pF capacitance | Minimizes high-frequency loading on signal paths when used as ESD clamp or transient suppressor in data lines near microcontrollers |
| 150 °C max junction temperature | Supports placement near heat sources (e.g., power MOSFETs, DC-DC inductors) without derating in industrial motor drives or lighting controllers |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Analog Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B47-Q | ±2 % tolerance (vs. ±5 %); 60 Ω rdif at IZ = 5 mA; higher test current shifts operating point | Better regulation stability in precision feedback loops but requires higher minimum bias current | Select when tighter voltage accuracy outweighs increased quiescent current in battery-powered systems |
| MMSZ47ET1G | Same 47 V nominal, ±5 %, but in SOD-123 package (larger footprint, no side-wettable flanks); 100 Ω rdif | Lacks AEC-Q101 qualification and SWF; unsuitable for automotive AOI-based assembly | Use only in non-automotive industrial or consumer applications where board space and inspection method are less constrained |
Compared with BZX884S-C47-QYL, the BZX884S-B47-Q offers superior voltage accuracy at higher bias current, while MMSZ47ET1G provides legacy compatibility at the cost of automotive readiness and thermal performance - making the C-series optimal for cost-sensitive, AEC-Q101-compliant designs requiring verified manufacturability.

FAQ
What is the marking code for BZX884S-C47-QYL?
The marking code for BZX884S-C47-QYL is '4W', laser-etched on the top surface of the DFN1006BD-2 package. The cathode is indicated by a visible bar adjacent to pin 1, consistent with Nexperia's SOD882BD orientation standard.
Can BZX884S-C47-QYL be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and parameter spread, causing current hogging and thermal runaway when paralleled. For >365 mW dissipation, use a single higher-rated Zener or implement active regulation with a pass transistor instead.
Is the 365 mW power rating valid for all PCB configurations?
No - the 365 mW rating applies specifically to mounting on a FR4 PCB with single-sided 70 μm copper, tin-plated, and the standard footprint per Figure 11. On thinner copper or no copper pour, derating to ≤200 mW is required to maintain Tj ≤ 150 °C.
Does BZX884S-C47-QYL support reflow soldering only, or can it be hand-soldered?
Reflow soldering is the only recommended method per Nexperia's documentation. Hand-soldering risks thermal damage due to the small thermal mass of the DFN1006BD-2 package and insufficient heat transfer control - leading to voided solder joints or delamination.
