Product details
Overview
BZX884S-B3V0-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 ±2 % tolerance, 365 mW power dissipation, and operates across −55 °C to +150 °C ambient temperature - qualified per AEC-Q101 for under-hood automotive use.
For engineers reviewing the BZX884S-B3V0-QYL datasheet, BZX884S-B3V0-QYL pinout, BZX884S-B3V0-QYL application, or BZX884S-B3V0-QYL equivalent, key selection criteria include its 3.0 V ±2 % breakdown voltage, side-wettable DFN1006BD-2 (SOD882BD) package for automated optical inspection, low 10 μA reverse current at VR = 2.5 V, and differential resistance of 325 Ω at IZ = 5 mA.
Technical Context
This device functions as a two-terminal shunt voltage regulator, maintaining stable output by conducting reverse current above its specified Zener voltage (VZ = 3.0 V). Its operation relies on controlled avalanche and Zener breakdown mechanisms, with temperature coefficient SZ = −3.5 mV/K at IZ = 5 mA and typical forward voltage VF ≤ 0.9 V at IF = 10 mA.
The SOD882BD package features side-wettable flanks enabling reliable solder-joint inspection via AOI, while its ultra-small 1.0 mm × 0.6 mm footprint supports high-density PCB layouts. Thermal resistance Rth(j-a) is 340 K/W on standard FR4, limiting continuous power handling without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.0 V ±2 % at IZ = 5 mA - ensures tight regulation tolerance for reference-sensitive analog rails |
| Differential Resistance (rdif) | 325 Ω typ. at IZ = 5 mA - defines small-signal impedance near regulation point, affecting load regulation stability |
| Reverse Current (IR) | 10 μA max. at VR = 2.5 V - guarantees low leakage before breakdown, critical for battery-powered standby circuits |
| Total Power Dissipation (Ptot) | 365 mW max. on FR4 PCB - sets maximum continuous DC or pulsed power handling without thermal derating |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables deployment in under-hood automotive environments and industrial control enclosures |
| Package | DFN1006BD-2 (SOD882BD), 0.65 mm pitch, 1.0 × 0.6 × 0.47 mm - supports miniaturized designs and automated optical solder-joint inspection |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTOL, TC, and ESD testing per AEC standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C3V0-Q | ±5 % tolerance (vs. ±2 %); higher max IR (20 μA @ VR = 2.5 V); identical package and VZ nominal | Suitable for non-critical biasing where cost sensitivity outweighs precision requirements | Select when ±5 % regulation margin is acceptable and unit cost reduction is prioritized |
| MMSZ4684T1G | 3.0 V ±5 %; SOD-123 package (2.7 × 1.6 mm); Ptot = 500 mW; not AEC-Q101 qualified | Preferred for non-automotive industrial boards requiring higher power headroom and manual rework compatibility | Choose only for non-automotive designs needing larger thermal mass and legacy footprint compatibility |
Compared with BZX884S-B3V0-QYL, the C3V0-Q offers lower cost but sacrifices regulation accuracy and leakage performance, while MMSZ4684T1G trades automotive qualification and miniaturization for higher power and easier hand-soldering - making the BZX884S-B3V0-QYL optimal for AEC-Q101-compliant, space-constrained applications demanding ±2 % stability.

FAQ
What is the maximum continuous reverse current this diode can sustain without degradation?
The BZX884S-B3V0-QYL is rated for a maximum forward current of 200 mA per absolute maximum ratings, but as a Zener diode, its continuous reverse (Zener) current is limited by power dissipation. At 25 °C ambient on standard FR4, the 365 mW rating permits up to ~122 mA average Zener current (IZ = Ptot / VZ ≈ 365 mW / 3.0 V), assuming no thermal derating. Derating begins above 25 °C at 2.15 mW/°C.
Does the side-wettable flank design require special stencil or reflow profile adjustments?
No special stencil or reflow profile is required beyond standard DFN-2 guidelines. The SOD882BD package uses a standard 0.65 mm pitch and 0.3 mm solder paste thickness; recommended reflow peak temperature is 260 °C for 10–15 seconds. Side-wettable flanks are compatible with standard Type 3 solder paste and standard AOI systems calibrated for DFN packages.
How does the −3.5 mV/K temperature coefficient affect regulation accuracy over temperature?
At IZ = 5 mA, the temperature coefficient of −3.5 mV/K means VZ decreases by 3.5 mV per Kelvin rise. Over a 100 K range (−40 °C to +60 °C), this introduces ~350 mV drift - approximately ±11.7 % of nominal 3.0 V. However, actual drift is mitigated by operating at higher test currents (e.g., 20 mA) where coefficient improves, and system-level compensation in feedback loops.
Is this part suitable for ESD protection in USB 2.0 data lines?
No - the BZX884S-B3V0-QYL is not optimized for high-speed ESD clamping. Its capacitance is unspecified at high frequency (only Cd ≤ 260 pF at 1 MHz, VR = 0 V), and its response time is too slow for USB 2.0 signal integrity. It is intended for DC/low-frequency voltage regulation and overvoltage clamping, not signal-line transient suppression.
