Product details
Overview
BZX884S-C3V6-QYL from Nexperia is a precision Zener voltage regulator diode in the BZX884S-Q series, designed for low-power voltage reference and regulation in space-constrained automotive and industrial circuits. It delivers a nominal 3.6 V breakdown voltage with ±5 % tolerance, 375 Ω typical differential resistance at 5 mA, and operates up to 150 °C junction temperature in the DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-C3V6-QYL datasheet, BZX884S-C3V6-QYL pinout, BZX884S-C3V6-QYL application, or BZX884S-C3V6-QYL equivalent, this page provides verified technical context, AEC-Q101-qualified specifications, side-wettable flank soldering guidance, and automotive-grade thermal performance data - all critical for ESD-sensitive bias networks and low-current reference design.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its 3.6 V nominal Zener voltage is specified at IZ = 5 mA, with a temperature coefficient of −3.5 mV/K and reverse current ≤5 μA at VR = 1.0 V.
The device uses a planar silicon process optimized for tight voltage tolerance and low dynamic impedance. Its side-wettable flanks enable automated optical inspection (AOI) of solder joints on FR4 PCBs, supporting high-reliability automotive assembly per AEC-Q101 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.40 V to 3.80 V at IZ = 5 mA - defines stable regulation point for low-current biasing |
| Differential Resistance (rdif) | 375 Ω typical at IZ = 5 mA - determines output voltage stability under small load variations |
| Reverse Current (IR) | ≤5 μA at VR = 1.0 V - ensures minimal leakage in standby or low-power modes |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables predictable forward conduction during transient clamping |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB with 70 μm copper - sets maximum continuous DC power handling in standard layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments |
| Thermal Resistance (Rth(j-a)) | 340 K/W - quantifies self-heating impact on voltage drift and reliability |
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 for AOI-compatible reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher potential in reverse-bias regulation; marked by bar on top surface |
| 2 | Anode (A) | Connected to lower potential (e.g., ground); forms current path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics |
| Side-wettable flanks (SWF) | Enables automated optical inspection of solder joints without X-ray, reducing manufacturing defect escape |
| ±5 % voltage tolerance | Supports cost-sensitive designs where tighter tolerance is not required, balancing accuracy and BOM cost |
| Low thermal resistance packaging | 340 K/W Rth(j-a) allows sustained operation at elevated ambient temperatures without derating |
| Wide operating temperature range | −55 °C to +150 °C junction rating enables use in under-dash, under-hood, and industrial control enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B3V6-Q | Nominal 3.6 V with ±2 % tolerance (vs. ±5 %); 350 Ω rdif at 5 mA | Higher accuracy required in precision analog front-ends; tighter thermal drift | Select when voltage stability over temperature and current is prioritized over cost |
| MMSZ4682T1G | 3.6 V Zener, SOD-123 package, 500 mW Ptot, no AEC-Q101 qualification | Larger footprint; suitable for non-automotive consumer or industrial boards with less stringent reliability demands | Choose for legacy board redesigns requiring drop-in compatibility with larger packages and higher power margin |
Compared with BZX884S-C3V6-QYL, the BZX884S-B3V6-Q offers tighter voltage control but lacks the side-wettable flank feature needed for automotive AOI, while MMSZ4682T1G trades AEC-Q101 compliance and miniaturization for higher power handling and broader distributor availability.

FAQ
What is the marking code for BZX884S-C3V6-QYL?
The marking code for BZX884S-C3V6-QYL is '4T', laser-etched on the top surface of the DFN1006BD-2 package. The cathode is indicated by a visible marking bar adjacent to pin 1, consistent with Table 4 in the Nexperia datasheet Rev. 2.
Can BZX884S-C3V6-QYL be used in place of a 3.3 V Zener diode?
No - BZX884S-C3V6-QYL has a nominal Zener voltage of 3.6 V (range 3.40–3.80 V), not 3.3 V. Substituting it for a 3.3 V part would shift bias points and reference levels by ~90 mV, potentially causing ADC errors or reset timing violations. Use BZX884S-C3V3-Q (code '4S') for 3.3 V regulation.
Is the DFN1006BD-2 package compatible with standard reflow profiles?
Yes - the DFN1006BD-2 package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Nexperia specifies a peak temperature of 260 °C max, with ramp rates and time above liquidus aligned to IPC-7095 guidelines. Figure 11 in the datasheet provides the recommended solder pad layout.
Does BZX884S-C3V6-QYL support bidirectional ESD protection?
No - it is a unidirectional Zener diode optimized for reverse-bias regulation, not symmetric ESD clamping. Its forward voltage is ≤0.9 V at 10 mA, but it lacks the low dynamic impedance and fast response of dedicated TVS diodes like PESD5V0S1BA. For bidirectional ESD protection, pair with a series resistor and complementary diode or use a dedicated ESD array.
