Product details
Overview
BZX884S-C27-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in compact automotive and industrial circuits. It delivers a nominal 27 V Zener voltage with ±5 % tolerance, 65 Ω typical differential resistance at IZ = 2 mA, and operates up to 150 °C junction temperature in the ultra-small DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-C27-QYL datasheet, BZX884S-C27-QYL pinout, BZX884S-C27-QYL application, or BZX884S-C27-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, low 50 pF capacitance at 1 MHz, and stable temperature coefficient of +21.4 mV/K at IZ = 2 mA.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage under varying load and temperature conditions. Its 27 V nominal Zener voltage is specified at IZ = 2 mA, with a differential resistance of 65 Ω (typ) ensuring minimal voltage deviation across current changes.
The device features an AEC-Q101 qualification, confirming suitability for automotive environments, and uses side-wettable flanks on its DFN1006BD-2 package to enable reliable solder-joint inspection during reflow assembly. Thermal resistance from junction to ambient is 340 K/W on standard FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 27 V nominal at IZ = 2 mA; ±5 % tolerance ensures predictable clamping in power rail supervision. |
| Differential Resistance rdif | 65 Ω typical at IZ = 2 mA; low impedance maintains voltage stability against load transients. |
| Temperature Coefficient SZ | +21.4 mV/K at IZ = 2 mA; positive drift enables predictable compensation in thermal-aware designs. |
| Reverse Current IR | 0.05 μA max at VR = 20.8 V; ultra-low leakage preserves battery life in always-on circuits. |
| Diode Capacitance Cd | 50 pF at f = 1 MHz, VR = 0 V; low capacitance avoids signal integrity degradation in high-frequency sensing paths. |
| Total Power Dissipation Ptot | 365 mW on FR4 PCB (70 μm Cu); sufficient headroom for transient suppression without heatsinking. |
| Junction Temperature Tj | −55 °C to +150 °C operating range; supports under-hood automotive and industrial control module deployment. |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks and 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar on top surface identifies this terminal for automated placement verification. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction enabling Zener breakdown regulation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock per JESD22 standards. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing manufacturing defect escape rate. |
| Ultra-small footprint | DFN1006BD-2 package saves >60 % board area vs. traditional SOD-323, critical for space-constrained ECUs and sensors. |
| Two tolerance options | ±2 % (B-series) and ±5 % (C-series) allow cost/performance trade-off; C27-QYL targets cost-sensitive automotive modules. |
| Wide voltage range | 2.4 V to 75 V coverage across E24 series enables single-family reuse across multiple voltage rails in one platform. |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B27-Q | ±2 % tolerance (vs. ±5 %), 40 Ω rdif at IZ = 5 mA; tighter regulation but higher cost. | Suitable where 27.0–27.5 V stability is required across temperature, e.g., precision ADC references. | Select when absolute voltage accuracy outweighs cost sensitivity and board area constraints. |
| MMSZ5254ET1G | 27 V ±5 %, SOD-123 package (1.8 mm × 1.4 mm), 100 Ω rdif, not AEC-Q101 qualified. | Acceptable for commercial-grade consumer power supplies but unsuitable for automotive use. | Choose only for non-automotive, cost-driven designs where larger footprint and lower reliability are acceptable. |
Compared with BZX884S-B27-Q, the C27-QYL trades 0.5 % tolerance and ~20 Ω higher rdif for lower unit cost and identical AEC-Q101 compliance; versus MMSZ5254ET1G, it offers 40 % smaller footprint, side-wettable flanks, and automotive qualification-critical for Tier 1 supply chain traceability.

FAQ
What is the maximum continuous reverse current the BZX884S-C27-QYL can handle?
The device supports up to 200 mA forward current (IF) per Absolute Maximum Ratings, but in Zener operation, its safe continuous reverse current is limited by power dissipation: at 27 V, IZ must remain ≤13.5 mA to stay within the 365 mW Ptot limit on standard FR4. Derating applies above 25 °C ambient.
Does the BZX884S-C27-QYL require a series resistor in typical regulator applications?
Yes-a current-limiting resistor is mandatory to set the Zener bias current (typically 2–10 mA). For a 30 V supply regulating to 27 V, a 220 Ω resistor delivers ~13.6 mA, staying within Ptot limits while ensuring stable breakdown conduction and minimizing temperature-induced drift.
How does the side-wettable flank design impact PCB assembly yield?
The side-wettable flanks on the DFN1006BD-2 package allow automated optical inspection (AOI) systems to verify solder fillet formation directly at the package edge, eliminating reliance on X-ray for void detection. This improves first-pass yield by >15 % in high-volume automotive SMT lines per Nexperia's process validation data.
Can BZX884S-C27-QYL be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging if paralleled. Even within the same batch, minor VZ mismatches (±5 %) lead to unequal current sharing and thermal runaway. Use a single higher-power Zener or active regulation instead.
