Product details
Overview
BZX884S-C3V0-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in space-constrained automotive and industrial circuits. It delivers a nominal 3.0 V Zener voltage with ±5 % tolerance, 325 Ω typical differential resistance at 5 mA, and operates up to 150 °C junction temperature in the ultra-small DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-C3V0-QYL datasheet, BZX884S-C3V0-QYL pinout, BZX884S-C3V0-QYL application, or BZX884S-C3V0-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, low 10 μA reverse current at 2.8 V, and thermal resistance of 340 K/W on standard FR4 PCB.
Technical Context
This Zener diode functions as a two-terminal shunt voltage regulator, maintaining stable output voltage across varying load currents by operating in reverse breakdown. Its design supports low-power biasing, voltage clamping, and reference generation in DC-DC feedback paths and sensor signal conditioning stages.
The device features a negative temperature coefficient of −3.5 mV/K at 5 mA, enabling predictable drift compensation in temperature-sensitive designs. Its 0.9 V forward voltage at 10 mA and 365 mW total power dissipation allow reliable operation under pulsed and continuous conditions on standard PCB layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B3V0-Q | Same package and Zener voltage but ±2 % tolerance (2.94–3.06 V vs. C-series 2.80–3.20 V). | Used where tighter regulation is required, e.g., precision ADC references or high-reliability safety monitors. | Select B3V0-Q only if system-level voltage margin permits tighter spec; otherwise C3V0-QYL offers better cost and availability. |
| MMSZ4677T1G | 3.0 V Zener, SOD-123 package (2.7 × 1.6 mm), ±5 %, 500 mW Ptot, higher rdif (400 Ω typ.). | Suitable for non-automotive, higher-power applications where board space is less constrained. | Choose MMSZ4677T1G only if legacy SOD-123 footprint must be retained; BZX884S-C3V0-QYL provides superior thermal performance and AEC-Q101 compliance. |
Compared with BZX884S-B3V0-Q, the C3V0-QYL trades voltage precision for broader tolerance and lower cost, while versus MMSZ4677T1G it delivers 3× smaller footprint, AEC-Q101 qualification, and side-wettable flanks-making it optimal for next-gen automotive and portable electronics.

FAQ
What is the maximum continuous Zener current for BZX884S-C3V0-QYL at 25 °C ambient?
At 25 °C ambient on a standard FR4 PCB, the maximum continuous Zener current is approximately 121 mA, calculated from Ptot = 365 mW and VZ = 3.0 V. Derating is required above 25 °C using Rth(j-a) = 340 K/W; at 85 °C ambient, max current drops to ~75 mA to maintain Tj ≤ 150 °C.
Does BZX884S-C3V0-QYL support reflow soldering only, or can it be hand-soldered?
Reflow soldering is the only recommended method per Nexperia's documentation. Hand-soldering is not advised due to the DFN1006BD-2 package's side-wettable flanks and thermal sensitivity-localized heat can damage the die or cause solder voiding. Reflow profiles must follow JEDEC J-STD-020 guidelines for MSLE Level 1.
How does the −3.5 mV/K temperature coefficient affect circuit performance?
The negative temperature coefficient means VZ decreases by 3.5 mV per °C rise in junction temperature. At 125 °C, VZ shifts down ~350 mV from its 25 °C value-so a nominal 3.0 V device operates near 2.65 V. This must be accounted for in overvoltage thresholds and reference stability budgets.
Is the marking code '4R' on BZX884S-C3V0-QYL standardized across all reels and lots?
Yes, '4R' is the official marking code defined in Table 4 of the datasheet for BZX884S-C3V0-Q variants, including QYL. It appears as a laser-etched alphanumeric mark adjacent to the cathode bar on the top surface and is consistent across all production lots and packaging formats (reel, cut tape, or tray).
