Product details
Overview
BZX884S-B8V2-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and regulation in compact automotive and industrial circuits. It delivers a nominal 8.2 V breakdown voltage with ±2 % tolerance, 365 mW power dissipation, and operates across −55 °C to +150 °C ambient temperature - validated per AEC-Q101 for under-hood automotive use.
For engineers reviewing the BZX884S-B8V2-QYL datasheet, BZX884S-B8V2-QYL pinout, BZX884S-B8V2-QYL application, or BZX884S-B8V2-QYL equivalent, key selection criteria include its 8.2 V Zener voltage at 5 mA, low 6.2 pF capacitance at 0 V, 0.7 μA max reverse current at 6.6 V, side-wettable DFN1006BD-2 package for automated optical inspection, and AEC-Q101 qualification for functional safety-critical subsystems.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage under varying load and temperature conditions. Its differential resistance of 40 Ω at IZ = 5 mA ensures tight regulation, while the +3.2 mV/K temperature coefficient enables predictable drift compensation in thermal-aware designs.
The device uses silicon planar epitaxial construction with cathode-anode terminal configuration in a leadless DFN1006BD-2 package. Side-wettable flanks support solder joint integrity verification via AOI, and the 0.65 mm pitch aligns with high-density PCB layouts requiring minimal board space.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.04 V to 8.36 V at IZ = 5 mA - defines precise regulation point for 8.2 V nominal rail stabilization |
| Tolerance | ±2 % - enables tighter voltage margin control than ±5 % variants in feedback loops and reference circuits |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB with 70 μm copper - sets maximum continuous power handling in standard layout |
| Reverse Current (IR) | ≤ 0.7 μA at VR = 6.6 V - ensures low leakage in standby or battery-powered modes |
| Diode Capacitance (Cd) | 6.2 pF at f = 1 MHz, VR = 0 V - minimizes signal coupling and noise injection in high-frequency analog paths |
| Differential Resistance (rdiff) | 40 Ω typical at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Temperature Coefficient (SZ) | +3.2 mV/K at IZ = 5 mA - allows accurate thermal drift modeling for compensated references |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for reliable reflow and AOI compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Connected to regulated output node; polarity marker (bar) identifies cathode for correct orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path enabling Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| Side-wettable flanks | Enables automated optical inspection of solder joints without X-ray, improving manufacturing yield and reliability traceability |
| Ultra-small footprint | DFN1006BD-2 package occupies only 0.6 mm² board area - ideal for space-constrained modules like ECU sub-assemblies |
| Low capacitance | 6.2 pF at 0 V reverse bias - preserves signal integrity in RF-adjacent or high-speed analog monitoring circuits |
| Stable temperature coefficient | +3.2 mV/K enables predictable drift behavior for temperature-compensated reference designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C8V2-Q | ±5 % tolerance (vs. ±2 %); higher max reverse current (1.0 μA at 6.6 V) | Suitable for non-critical biasing where cost outweighs precision | Select when tighter voltage stability is not required and BOM cost reduction is prioritized |
| MMSZ5236B-7-F | Same 8.2 V nominal, ±5 % tolerance; SOD-123 package (larger, no side-wettable flanks) | Lacks AEC-Q101 qualification and AOI-friendly packaging | Choose only for non-automotive, non-high-reliability applications where legacy SOD-123 footprint is mandated |

FAQ
What is the maximum reverse voltage this Zener diode can withstand before breakdown?
The BZX884S-B8V2-QYL has a nominal Zener voltage of 8.2 V, with guaranteed breakdown occurring between 8.04 V and 8.36 V at 5 mA test current. Its absolute maximum reverse voltage is not defined separately - operation beyond the specified VZ range risks exceeding power or thermal limits. The device is rated for continuous reverse operation only within its specified Zener region.
Can this diode be used in place of a standard 1N4736A?
No - the 1N4736A is a through-hole 8.2 V Zener in DO-41 package with ±5 % tolerance and 1 W power rating, whereas the BZX884S-B8V2-QYL is a surface-mount, AEC-Q101-qualified part with ±2 % tolerance, 365 mW rating, and DFN1006BD-2 footprint. Direct substitution requires PCB redesign, thermal reassessment, and validation of automotive qualification requirements.
Does the side-wettable flank design affect soldering profile requirements?
No - the side-wettable flank geometry does not alter reflow profile specifications. Nexperia specifies standard JEDEC J-STD-020-compliant reflow for the DFN1006BD-2 package. The flank feature solely enables post-solder AOI verification of fillet formation and does not require modified peak temperature, time above liquidus, or ramp rates.
How does the +3.2 mV/K temperature coefficient impact circuit performance?
The +3.2 mV/K coefficient means the Zener voltage increases by approximately 3.2 mV per degree Celsius rise in junction temperature. In a 50 °C ambient-to-junction swing, this yields ~160 mV total drift - acceptable for non-precision references but requiring compensation (e.g., with a negative-tempco component) in high-accuracy applications like calibration standards or metrology-grade sensors.
