Product details
Overview
BZX884S-B12-QYL from Nexperia is a 12 V ±2 % Zener voltage regulator diode in an ultra-small DFN1006BD-2 (SOD882BD) leadless SMD package with side-wettable flanks, rated for 365 mW total power dissipation at 25 °C, qualified to AEC-Q101, and designed for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the BZX884S-B12-QYL datasheet, BZX884S-B12-QYL pinout, BZX884S-B12-QYL application, or BZX884S-B12-QYL equivalent, this part supports stable 12 V regulation under low-current bias (IZ = 5 mA), features 8.0 Ω typical differential resistance, and delivers automotive-grade reliability in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 11.8–12.2 V nominal voltage at 5 mA test current, with a temperature coefficient of +6.0 mV/K at that condition. Its low 8.0 Ω dynamic impedance ensures minimal output voltage variation under load transients.
The device uses a planar silicon junction structure optimized for tight tolerance and low leakage, with reverse current limited to ≤0.1 μA at VR = 9.0 V and thermal resistance of 340 K/W from junction to ambient on standard FR4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.8 V to 12.2 V at IZ = 5 mA - defines precise regulation point for 12 V rail stabilization |
| Tolerance | ±2 % - enables high-accuracy feedback loops without external trimming |
| Differential Resistance (rdif) | 50 Ω max at IZ = 5 mA - limits output voltage shift under current changes |
| Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C on FR4 - sets maximum continuous bias current limit (~30 mA at 12 V) |
| Reverse Current (IR) | ≤0.1 μA at VR = 9.0 V - ensures negligible quiescent leakage in standby circuits |
| Thermal Resistance (Rth(j-a)) | 340 K/W - determines junction temperature rise under power dissipation |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884B12-7-F | Same 12 V ±2 % spec, but in SOD-323 package (1.7 mm × 1.3 mm); 500 mW Ptot rating | Larger footprint; higher power handling but no side-wettable flanks | Select when board space permits larger package and higher surge energy absorption is required |
| MMSZ5242B-TP | 12 V ±5 % tolerance; SOD-123 package; 500 mW rating; 100 Ω rdif max at 20 mA | Looser tolerance and higher impedance reduce precision in feedback paths | Acceptable for non-critical clamping where cost is prioritized over regulation accuracy |
Compared with BZX884S-B12-QYL, BZX884B12-7-F offers higher power margin in a larger package, while MMSZ5242B-TP trades precision and compactness for cost and availability-making the QYL variant optimal for AEC-Q101-compliant, space-constrained 12 V reference designs.

FAQ
What is the maximum reverse current at 9.0 V for BZX884S-B12-QYL?
The maximum reverse current (IR) is 0.1 μA at VR = 9.0 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This low leakage ensures minimal power loss in always-on monitoring circuits and maintains accuracy in high-impedance reference nodes.
Can BZX884S-B12-QYL be used in reflow soldering processes?
Yes-BZX884S-B12-QYL is qualified for reflow soldering only, using the SOD882BD footprint defined in Figure 11. Its side-wettable flanks enable reliable solder joint inspection, and the package withstands peak temperatures up to 260 °C per J-STD-020.
How does the temperature coefficient affect regulation stability?
At IZ = 5 mA, the temperature coefficient is +6.0 mV/K, meaning output voltage increases by ~6 mV per °C rise. For a 100 °C ambient-to-junction swing, this yields ~600 mV drift-requiring layout-level thermal isolation or compensation in high-precision references.
Is the cathode marked on the BZX884S-B12-QYL package?
Yes-the cathode (pin 1) is identified by a visible marking bar on the top surface of the DFN1006BD-2 package, per Figure 10 and Note 2 in the datasheet. This aligns with industry-standard polarity identification for automated placement verification.
