Product details
Overview
BZX884S-B6V2-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 6.2 V nominal breakdown voltage with 40 Ω typical differential resistance at 5 mA and −0.4 mV/K temperature coefficient. It supports automotive-grade power rail stabilization and low-power sensor biasing in space-constrained PCBs.
For engineers reviewing the BZX884S-B6V2-QYL datasheet, BZX884S-B6V2-QYL pinout, BZX884S-B6V2-QYL application, or BZX884S-B6V2-QYL equivalent, key selection criteria include Zener voltage tolerance, side-wettable flank solderability, AEC-Q101 qualification, thermal resistance (340 K/W), and low reverse leakage (≤3 μA at 4.96 V).
Technical Context
This Zener diode operates in reverse-biased breakdown mode with tightly controlled 6.2 V nominal Zener voltage (B-series ±2 %), delivering stable reference voltage under regulated current conditions (IZ = 5 mA). Its low 40 Ω dynamic impedance ensures minimal output voltage variation across load changes.
Designed for surface-mount assembly on FR4 PCBs with single-sided 70 μm copper, it features side-wettable flanks for automated optical inspection (AOI) of solder joints and achieves 365 mW total power dissipation at Tamb = 25 °C with junction temperature limited to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V to 6.32 V at IZ = 5 mA - tight ±2 % tolerance enables accurate voltage clamping in feedback loops |
| Differential Resistance (rdif) | 40 Ω typ. at IZ = 5 mA - low impedance maintains stable regulation under varying load currents |
| Temperature Coefficient (SZ) | −0.4 mV/K at IZ = 5 mA - near-zero TC minimizes drift over −55 °C to +150 °C ambient range |
| Reverse Current (IR) | ≤3 μA at VR = 4.96 V - low leakage preserves battery life in always-on circuits |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB - sufficient headroom for transient overvoltage suppression in 3.3 V/5 V systems |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables use as low-drop rectifier or ESD clamp in dual-role designs |
| Junction-to-Ambient Rth | 340 K/W - defines thermal derating slope for sustained operation above 25 °C ambient |
Pinout & Package
DFN1006BD-2 (SOD882BD) leadless plastic package: 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch, side-wettable flanks for AOI-compatible reflow soldering. Cathode identified by marking bar on 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 |
|---|---|---|---|
| BZX884S-C6V2-Q | ±5 % tolerance (5.8 V–6.6 V), higher 120 Ω rdif, +3.7 mV/K SZ | Acceptable for non-critical biasing where cost sensitivity outweighs precision | Select when ±5 % voltage margin is acceptable and thermal drift is mitigated by system calibration |
| MMSZ4687T1G | 6.2 V ±5 %, SOD-123 package (2.7 mm × 1.4 mm), 500 mW Ptot, 100 Ω rdif | Higher power handling but 4.5× larger footprint; no side-wettable flanks | Choose for high-reliability industrial designs requiring legacy package compatibility and higher surge capability |
Compared with BZX884S-B6V2-QYL, the C6V2-Q offers lower cost but sacrifices regulation stability and thermal performance, while MMSZ4687T1G trades miniaturization for ruggedness and legacy manufacturability-making the BZX884S-B6V2-QYL optimal for space-constrained automotive and portable electronics where precision and AEC-Q101 compliance are mandatory.

FAQ
What is the maximum continuous reverse current the BZX884S-B6V2-QYL can sustain without degradation?
The device is rated for 200 mA maximum forward current, but as a Zener diode, its safe continuous reverse current is determined by power dissipation limits. At 25 °C ambient on a standard FR4 PCB, it supports up to 58.7 mA (365 mW ÷ 6.2 V) continuously without exceeding 150 °C junction temperature. Derating is required above 25 °C per the 340 K/W thermal resistance.
How does the side-wettable flank design impact solder joint reliability during reflow?
Side-wettable flanks enable full optical visibility of solder meniscus formation along the terminal edges during automated optical inspection (AOI), allowing detection of voids, insufficient solder, or bridging that would be invisible on conventional DFN packages. This directly improves first-pass yield and field reliability in high-volume automotive manufacturing.
Can BZX884S-B6V2-QYL be used in place of a 6.2 V TL431-based shunt regulator?
No-it lacks the active feedback and adjustable reference architecture of the TL431. The BZX884S-B6V2-QYL provides passive, fixed-voltage clamping only. It cannot replicate the TL431's 2.5 V reference, adjustable output, or high-impedance cathode drive. Use only where simple, low-cost, low-current Zener action suffices.
Is the 6.2 V Zener voltage specified at DC or pulsed test conditions?
The 6.08 V to 6.32 V specification is measured under DC conditions at IZ = 5 mA, per Table 8. Pulse testing (tp ≤ 300 μs, δ ≤ 0.02) applies only to forward voltage (VF) characterization-not Zener voltage. All regulation parameters assume steady-state DC operation unless explicitly noted otherwise in the datasheet.
