Product details
Overview
BZX884S-B3V3-QYL from Nexperia is a ±2 % tolerance Zener diode in ultra-small DFN1006BD-2 (SOD882BD) package, designed for precision voltage regulation and reference functions at 3.3 V nominal breakdown voltage with 5 μA reverse current and 350 Ω differential resistance at IZ = 5 mA. It operates across −55 °C to +150 °C ambient and supports automotive-grade power rail stabilization.
For engineers reviewing the BZX884S-B3V3-QYL datasheet, BZX884S-B3V3-QYL pinout, BZX884S-B3V3-QYL application, or BZX884S-B3V3-QYL equivalent, this page delivers verified electrical specs, side-wettable flank package details, AEC-Q101 qualification status, thermal resistance (340 K/W), and automotive-compatible Zener characteristics - all critical for low-power biasing, overvoltage clamping, and reference design validation.
Technical Context
This Zener diode uses silicon planar technology to achieve stable 3.3 V regulation with tight ±2 % tolerance and low temperature coefficient (−3.5 mV/K typical at IZ = 5 mA). Its 350 Ω dynamic impedance ensures predictable voltage drop under varying load currents up to 200 mA forward/5 mA Zener test conditions.
The DFN1006BD-2 package features side-wettable flanks for automated optical solder-joint inspection and supports reflow-only assembly on FR4 PCBs with 70 μm copper. Thermal resistance from junction to ambient is 340 K/W under standard mounting conditions, enabling reliable operation at Tj ≤ 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.23 V to 3.37 V at IZ = 5 mA - defines precise regulation point for 3.3 V rail referencing |
| Tolerance | ±2 % - enables high-accuracy voltage references without post-calibration |
| Differential Resistance (rdif) | 350 Ω typical at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | 5 μA max at VR = 1 V - ensures low leakage in standby and battery-powered circuits |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous Zener current limit (~110 mA at 3.3 V) |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines conduction loss when used as clamp or ESD path |
| Junction Temperature (Tj) | 150 °C max - supports operation in under-hood automotive environments |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with 0.65 mm pitch and side-wettable flanks for automated solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |

| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray |
| Ultra-small footprint | 0.6 mm width allows placement in space-constrained modules like camera ECUs and body controllers |
| Low thermal resistance | 340 K/W junction-to-ambient enables stable regulation without heatsinking at ≤100 mW dissipation |
| Wide operating temperature | −55 °C to +150 °C ambient range supports deployment in under-dash and powertrain locations |
Applications
| Automotive Power Rail Stabilization | Low-Power Sensor Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884B3V3 | Same Zener voltage and ±2 % tolerance, but lacks AEC-Q101 qualification and side-wettable flanks | Restricted to industrial/commercial use; not approved for automotive production | Select only if automotive qualification is unnecessary and cost is prioritized over long-term reliability verification |
| MMSZ4685 | 3.3 V Zener with ±5 % tolerance and SOD-123 package (1.7 mm × 1.3 mm); higher rdif (600 Ω) | Larger footprint and looser regulation limit use in high-precision reference roles | Choose when board space permits larger package and ±5 % tolerance suffices for non-critical biasing |
Compared with BZX884S-B3V3-QYL, BZX884B3V3 omits automotive qualification and AOI-ready packaging, while MMSZ4685 trades precision and miniaturization for broader availability and legacy footprint compatibility - making the QYL variant optimal for new automotive designs requiring both size and reliability assurance.

FAQ
What is the maximum continuous Zener current for BZX884S-B3V3-QYL?
The device supports up to 110 mA continuous Zener current at 3.3 V, derived from its 365 mW power rating on FR4 PCB (Ptot/VZ = 365 mW / 3.3 V ≈ 110 mA). This assumes ambient temperature ≤25 °C and standard mounting; derating applies above 25 °C per the 340 K/W thermal resistance.
Does BZX884S-B3V3-QYL support reflow-only assembly?
Yes - Nexperia specifies reflow soldering as the sole recommended method for the DFN1006BD-2 package. The side-wettable flanks enable automated optical inspection of solder joints, and the footprint (1.3 mm × 0.8 mm lands, 0.4 mm solder mask opening) is optimized for lead-free reflow profiles per J-STD-020.
How does the −3.5 mV/K temperature coefficient affect regulation accuracy?
At IZ = 5 mA, the typical −3.5 mV/K coefficient means output voltage decreases by ~3.5 mV per °C rise in junction temperature. Over a 100 °C range (−40 °C to +60 °C ambient), this introduces ~350 mV drift - mitigated by using low-power biasing (<1 mA) or pairing with temperature-compensated circuits in precision references.
Is the cathode marking visible under standard optical inspection?
Yes - the cathode is identified by a laser-marked bar on the top surface of the DFN1006BD-2 package, positioned adjacent to pin 1. This marking is fully compatible with automated optical inspection (AOI) systems configured for side-wettable flank packages, and aligns with IPC-A-610 Class 2/3 requirements for polarity identification.
