Product details
Overview
BZX884S-C5V1-QYL from Nexperia is a ±5 % tolerance Zener voltage regulator diode in a DFN1006BD-2 (SOD882BD) leadless SMD package, rated for 5.1 V nominal breakdown at IZ = 5 mA, with 400 Ω typical differential resistance and 2 μA max reverse current at VR = 3.0 V, used for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the BZX884S-C5V1-QYL datasheet, BZX884S-C5V1-QYL pinout, BZX884S-C5V1-QYL application, or BZX884S-C5V1-QYL equivalent, this page delivers verified Zener parameters, AEC-Q101 qualification status, side-wettable flank soldering guidance, thermal resistance (340 K/W), and automotive-grade reliability data - all confirmed from Nexperia's official Rev. 2 product data sheet dated 5 May 2021.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable 5.1 V regulation across load and line variations, with temperature coefficient of −2.7 mV/K at IZ = 5 mA and low 170 pF capacitance at 1 MHz/0 V, enabling use in noise-sensitive analog references and fast transient clamp circuits.
Its DFN1006BD-2 package features side-wettable flanks for automated optical inspection (AOI) of solder joints, supports reflow-only assembly, and delivers 365 mW total power dissipation on standard FR4 PCBs with 70 μm copper - validated per IEC 60134 limiting values and AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 5.1 V at IZ = 5 mA - defines precise regulation point for 5 V rail stabilization and feedback sensing. |
| Tolerance | ±5 % - ensures predictable clamping threshold across production lots without binning. |
| Differential Resistance (rdif) | 400 Ω typ. at IZ = 5 mA - determines output impedance and load regulation error under varying current. |
| Reverse Current (IR) | ≤2 μA at VR = 3.0 V - guarantees minimal leakage in standby or high-impedance bias networks. |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous power handling without derating at Tamb = 25 °C. |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive environments and industrial control enclosures. |
| Thermal Resistance (Rth(j-a)) | 340 K/W - quantifies junction-to-ambient heat transfer efficiency on standard single-sided PCB layout. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with 0.65 mm pitch and side-wettable flanks for AOI-compatible reflow soldering. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; polarity must be observed for correct reverse-bias operation. |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes Zener conduction path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics modules. |
| Side-wettable flanks | Enables automated optical inspection of solder fillets on both package edges, improving manufacturing yield. |
| Ultra-small footprint | 0.6 mm width allows placement in space-constrained PCB areas such as sensor modules and ADAS ECUs. |
| Low capacitance | 170 pF at 1 MHz/0 V minimizes signal distortion in high-frequency clamp or ESD protection paths. |
| Wide operating temperature | −55 °C to +150 °C ambient range supports deployment in under-dash, under-hood, and industrial motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B5V1-Q | ±2 % tolerance vs. ±5 %; 400 Ω rdif vs. 480 Ω; identical package and thermal specs. | Higher precision required in feedback loops where 100 mV variation is unacceptable. | Select when tighter regulation stability outweighs cost premium and availability constraints. |
| MMSZ5231B-TP | SOD-123 package (2.7 mm × 1.6 mm); 5.1 V ±5 %; 17 Ω rdif; 500 mW Ptot. | Larger footprint but lower dynamic impedance suits higher-current regulation (>10 mA). | Choose for non-automotive designs needing lower Zener impedance and relaxed board space constraints. |
Compared with BZX884S-C5V1-QYL, the BZX884S-B5V1-Q offers tighter tolerance at higher cost and reduced supply chain flexibility, while MMSZ5231B-TP trades miniaturization for lower impedance and higher power handling - making the QYL variant optimal for AEC-Q101-compliant, space-constrained 5 V rail clamping.

FAQ
What is the maximum forward voltage for BZX884S-C5V1-QYL?
The maximum forward voltage is 0.9 V at IF = 10 mA, measured under pulse test conditions (tp ≤ 300 μs, duty cycle ≤ 0.02). This value reflects worst-case conduction loss during forward-bias fault conditions and is specified in Table 1 and Table 7 of the Nexperia datasheet Rev. 2.
Is BZX884S-C5V1-QYL suitable for reflow soldering only?
Yes - Nexperia explicitly recommends reflow soldering only for the DFN1006BD-2 package. Wave or hand soldering is not supported due to thermal limitations and side-wettable flank design. The recommended reflow profile and footprint dimensions are provided in Figure 11 of the datasheet.
How does the temperature coefficient affect regulation accuracy?
At IZ = 5 mA, the temperature coefficient is −2.7 mV/K, meaning output voltage decreases by 2.7 mV per 1 K rise in junction temperature. Over a 100 K range (−40 °C to +60 °C ambient), this contributes up to ±270 mV drift - a key factor in high-accuracy reference designs.
Can BZX884S-C5V1-QYL replace BZX84-C5V1 in existing designs?
No - BZX84-C5V1 uses SOT-23 packaging (3.0 mm × 1.4 mm), while BZX884S-C5V1-QYL uses DFN1006BD-2 (1.0 mm × 0.6 mm). Pin compatibility, thermal performance, and soldering process differ significantly; redesign of footprint and layout is required for substitution.
