Product details
Overview
BZX884S-C12-QYL from Nexperia is a 12 V ±5 % tolerance Zener diode in a leadless DFN1006BD-2 (SOD882BD) package, designed for precision voltage regulation and reference functions in space-constrained automotive and industrial circuits. It delivers 12.0 V nominal Zener voltage at 5 mA test current, 50 Ω typical differential resistance, and operates up to 150 °C junction temperature with 365 mW power dissipation on FR4 PCB.
For engineers reviewing the BZX884S-C12-QYL datasheet, BZX884S-C12-QYL pinout, BZX884S-C12-QYL application, or BZX884S-C12-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, 12 V regulation stability across temperature, and ultra-small 1.0 mm × 0.6 mm footprint for high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable 12 V output under varying load and input conditions. Its 50 Ω typical dynamic impedance ensures minimal voltage deviation with ±1 mA current change at 5 mA bias, while the +6.0 mV/K temperature coefficient enables predictable drift compensation in thermal-aware designs.
The device uses silicon planar epitaxial construction with cathode-anode polarity defined by a visible marking bar on the package top surface. It is rated for continuous operation from −55 °C to +150 °C ambient and supports reflow soldering only per JEDEC J-STD-020 guidelines.
Key Specifications

|---|---|
| Zener Voltage VZ | 11.4 V to 12.7 V at IZ = 5 mA - defines regulation window for 12 V rail stabilization |
| Differential Resistance rdif | 50 Ω typ. at IZ = 5 mA - determines output voltage variation under load transients |
| Temperature Coefficient SZ | +6.0 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius rise |
| Max Power Dissipation Ptot | 365 mW on FR4 PCB (70 μm Cu) - sets maximum continuous DC or pulsed power handling |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - limits conduction loss when used in forward-biased protection paths |
| Junction Temperature Tj | −55 °C to +150 °C - enables deployment in under-hood automotive and industrial environments |
| Reverse Current IR | 0.1 μA max at VR = 9.0 V - ensures low leakage in high-impedance reference nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B12-Q | 12 V ±2 % tolerance, 40 Ω typical rdif, +6.0 mV/K SZ | Higher precision needed for metrology-grade references | Select when tighter voltage tolerance and lower dynamic impedance are critical for calibration-critical systems |

FAQ
What is the marking code for BZX884S-C12-QYL?
The marking code for BZX884S-C12-QYL is '4A', laser-etched on the top surface of the DFN1006BD-2 package adjacent to the cathode-marking bar. This two-character code uniquely identifies the 12 V ±5 % variant within the BZX884S-Q family and is verified per Table 4 of the official Nexperia datasheet Rev. 2.
Can BZX884S-C12-QYL be used in place of a 1N4742A?
No-BZX884S-C12-QYL is not a drop-in replacement for 1N4742A due to fundamental package and thermal differences: it uses a 1.0 mm × 0.6 mm DFN instead of DO-41, has 365 mW power rating versus 1 W, and requires reflow-only assembly. While both regulate at ~12 V, PCB layout, thermal relief, and solder process must be redesigned.
Does this Zener diode support bidirectional ESD protection?
No-BZX884S-C12-QYL is a unidirectional Zener diode optimized for reverse-bias voltage regulation, not transient suppression. Its 0.9 V forward voltage and lack of specified IPP/VCL parameters confirm it is unsuitable for IEC 61000-4-2 ESD clamping; dedicated TVS diodes like PESD5V0S1BA should be used instead.
What is the thermal resistance from junction to ambient (Rth(j-a))?
The thermal resistance from junction to ambient is 340 K/W when mounted on a standard FR4 PCB with single-sided 70 μm copper and tin plating, per Table 6 of the datasheet. This value assumes free-air convection and defines the temperature rise per watt of dissipated power under those specific board conditions.
