Product details
Overview
BZX884S-B15-QYL from Nexperia is a ±2 % tolerance Zener voltage regulator diode with nominal 15 V breakdown voltage, housed in an ultra-small DFN1006BD-2 (SOD882BD) leadless SMD package featuring side-wettable flanks. It delivers 365 mW total power dissipation at 25 °C on FR4 PCB, exhibits 10.5 mV/K temperature coefficient at 5 mA, and is AEC-Q101 qualified for automotive voltage reference and overvoltage protection circuits.
For engineers reviewing the BZX884S-B15-QYL datasheet, BZX884S-B15-QYL pinout, BZX884S-B15-QYL application, or BZX884S-B15-QYL equivalent, this part supports precision biasing in low-power sensor interfaces, ESD-tolerant I/O clamping, and stable reference generation in space-constrained automotive ECUs where thermal performance and solder joint inspection are critical.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 15 V reference across its terminals under regulated current conditions (IZ = 5 mA). Its differential resistance of 50 Ω (typ.) ensures minimal voltage deviation with load current changes, while the 10.5 mV/K temperature coefficient enables predictable drift compensation in ambient ranges from −55 °C to +150 °C.
The device uses a planar silicon junction structure optimized for low leakage (IR ≤ 0.05 μA at VR = 12 V) and fast transient response, with capacitance of 75 pF at 0 V reverse bias (1 MHz). Its side-wettable flanks support automated optical inspection (AOI) of solder joints in high-reliability reflow processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 14.7 V to 15.3 V at IZ = 5 mA - tight ±2 % tolerance enables accurate voltage clamping without post-production trimming |
| Differential Resistance (rdif) | 50 Ω (typ.) at IZ = 5 mA - low impedance stabilizes output against current fluctuations in feedback loops |
| Temperature Coefficient (SZ) | 10.5 mV/K at IZ = 5 mA - predictable thermal drift allows compensation in wide-temperature automotive environments |
| Reverse Current (IR) | ≤ 0.05 μA at VR = 12 V - ultra-low leakage preserves battery life in always-on vehicle modules |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB (70 μm Cu) - sufficient headroom for transient surge absorption in 12 V rail protection |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in engine bay and powertrain control units |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - enables <1 mm² board area usage in dense ADAS sensor nodes |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal leadless plastic package with side-wettable flanks, 0.65 mm pitch, and marking bar indicating cathode. Dimensions: 1.0 mm × 0.6 mm × 0.47 mm body height; solderable lead ends protrude ≤ 0.02 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node in reverse-bias configuration; marking bar identifies this terminal for orientation during placement |
| 2 | Anode (A) | Connected to lower-potential node (e.g., ground or return path); forms the reference output node when cathode is biased above anode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per JESD22 standards |
| Side-wettable flanks (SWF) | Enables 100 % automated optical inspection (AOI) of solder fillets without X-ray, reducing manufacturing defect escape rate |
| ±2 % voltage tolerance | Eliminates need for binning or external calibration in 15 V reference designs for CAN transceiver biasing and MCU reset supervision |
| Ultra-small footprint | 0.6 mm width allows placement between fine-pitch QFN pins or beneath connectors in compact telematics modules |
| Low thermal resistance | Rth(j-a) = 340 K/W on standard FR4 - maintains junction temperature <125 °C at 200 mA peak pulse in 70 °C ambient |
Applications
| Automotive Sensor Biasing | USB Port Overvoltage Protection |

FAQ
What is the maximum continuous reverse current the BZX884S-B15-QYL can sustain without degradation?
The device is rated for a maximum forward current of 200 mA per Absolute Maximum Ratings (Table 5), but sustained reverse conduction is limited by power dissipation. At 25 °C ambient on standard FR4, continuous reverse current must be kept ≤24.3 mA to stay within 365 mW Ptot. Derating is required above 25 °C using Rth(j-a) = 340 K/W.
How does the side-wettable flank design impact solder joint reliability in reflow assembly?
Side-wettable flanks enable full optical visibility of solder meniscus formation during reflow, allowing AOI systems to verify wetting quality, coplanarity, and voiding-critical for zero-defect manufacturing in automotive electronics. This eliminates reliance on X-ray for process validation and reduces field failure risk from insufficient solder adhesion.
Can the BZX884S-B15-QYL be used in series or parallel configurations for higher voltage or current capability?
Series connection is feasible for higher voltage references (e.g., two 15 V diodes for 30 V), but matching VZ and temperature coefficients is essential to avoid imbalance. Parallel operation is not recommended due to negative dynamic resistance characteristics causing current hogging; use a single higher-power Zener or active regulation instead.
What is the significance of the 'Q' suffix in BZX884S-B15-QYL, and how does it differ from non-Q variants?
The 'Q' denotes AEC-Q101 qualification, confirming the device meets stress test requirements for automotive applications-including temperature cycling, HAST, and mechanical shock. Non-Q variants lack this validation and are restricted to commercial/industrial use; the 'Q' suffix also implies tighter process controls and lot-level traceability required by Tier 1 automotive suppliers.
