Product details
Overview
BC847CQB-Q from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in a DFN1110D-3 (SOT8015) leadless package, rated for 45 V VCEO, 100 mA IC, and hFE = 420–800 at VCE = 5 V / IC = 2 mA. It serves as a compact, high-reliability switching and amplification device in space-constrained automotive and industrial PCBs.
For engineers reviewing the BC847CQB-Q datasheet, BC847CQB-Q pinout, BC847CQB-Q application, or BC847CQB-Q equivalent, key selection criteria include its side-wettable flanks for AOI-compatible solder joint inspection, 0.48 mm profile height, AEC-Q101 qualification, and guaranteed hFE binning for predictable gain matching in production designs.
Technical Context
This transistor operates as a silicon NPN bipolar junction device with base-controlled current amplification. Its design supports linear amplification (VCE ≥ 1 V) and saturated switching (VCE(sat) ≤ 400 mV at IC = 100 mA / IB = 5 mA), with thermal resistance Rth(j-a) of 298 K/W on 70 µm FR4 copper.
The DFN1110D-3 package integrates side-wettable flanks to enable automated optical inspection of solder fillets, while maintaining a 1.1 × 1.0 × 0.48 mm footprint - 45% smaller than comparable SOT23 devices. Junction temperature is rated to 150 °C, supporting operation in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage with open base; defines upper rail limit in 12 V/24 V automotive switching circuits. |
| IC | 100 mA continuous - Sustained collector current rating; supports driving small relays, LEDs, or logic-level signal buffers. |
| hFE | 420–800 at VCE = 5 V, IC = 2 mA - Tight DC current gain bin ensures consistent base drive requirements across production batches. |
| VCE(sat) | ≤ 400 mV at IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| Ptot | 420 mW on 70 µm FR4 PCB - Total power dissipation limit determines maximum safe I2R + VCEIC load under standard board layout. |
| fT | 100 MHz - Transition frequency enables stable operation up to low-MHz signal amplification and fast edge switching. |
| Package | DFN1110D-3 (SOT8015) - 1.1 × 1.0 × 0.48 mm leadless package with side-wettable flanks for AOI-capable reflow assembly. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin surface-mount package with exposed thermal pad (not electrically connected), side-wettable flanks, and 0.65 mm pitch. Dimensions: 1.1 mm × 1.0 mm × 0.48 mm body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires 0.5–5 mA drive to saturate 100 mA collector load; sensitive to ESD (VEBO = 6 V max). |
| 2 | Emitter (E) | Reference terminal for biasing; tied to ground or low-side return path; forms current mirror reference in amplifier configurations. |
| 3 | Collector (C) | High-side output node; connects to load (e.g., relay coil, LED anode); must remain ≤ 45 V relative to emitter under all conditions. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114; supports under-hood deployment. |
| Side-wettable flanks | Enables 100% automated optical inspection (AOI) of solder joints without X-ray; eliminates manual visual checks in high-volume SMT lines. |
| 0.48 mm profile height | Reduces Z-axis stack-up in multi-layer modules (e.g., ADAS sensor housings, infotainment front panels) where mechanical clearance is < 0.6 mm. |
| 420–800 hFE bin | Guaranteed minimum gain ensures predictable base resistor sizing across production lots-critical for cost-sensitive discrete logic interface designs. |
| Low Rth(j-a) | 298 K/W on 70 µm FR4 allows 350 mW dissipation at ΔT = 105 K-enabling sustained 100 mA switching without external heatsinking. |
Applications
| Automotive Door Module | Industrial Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847C,215 (SOT23) | Same electrical specs but in legacy SOT23-3 package; no side-wettable flanks; 1.3 × 1.75 × 1.1 mm height. | Lacks AOI capability; unsuitable for automotive high-reliability lines requiring solder-joint verification. | Select only for non-automotive, cost-sensitive designs where board space and inspection are not constraints. |
| MMBT3904LT1G | hFE = 100–300 (looser bin); VCEO = 40 V; not AEC-Q101 qualified; SOT23 package. | Not approved for automotive use; lower gain consistency increases base resistor tolerance sensitivity. | Acceptable for consumer-grade switching where qualification and gain stability are secondary to BOM cost. |
Compared with BC847C,215 and MMBT3904LT1G, BC847CQB-Q delivers verified automotive qualification, AOI-ready packaging, and tighter hFE binning-making it the sole choice when production traceability, solder-joint reliability, and gain-matched performance are mandatory.

FAQ
Is BC847CQB-Q pin-compatible with BC847C in SOT23?
No. BC847CQB-Q uses a DFN1110D-3 (SOT8015) 3-pin leadless package with side-wettable flanks and 0.65 mm pitch, while BC847C uses SOT23-3 with 2.3 mm pitch and gull-wing leads. The pin numbering (B-E-C) matches functionally, but physical layout, soldering method, and PCB footprint are incompatible.
What does the 'Q' suffix indicate in BC847CQB-Q?
The 'Q' suffix denotes AEC-Q101 qualification per Automotive Electronics Council standards. It confirms that the device has passed stress tests including HTGB, HTRB, temperature cycling, and ESD (HBM ≥ 2 kV), and is approved for automotive applications per Nexperia's qualification report.
Can BC847CQB-Q replace BC847BQB-Q in existing designs?
Yes, with design validation. Both share identical package, pinout, and absolute maximum ratings, but BC847CQB-Q offers higher hFE (420–800 vs. 200–450). This may reduce required base drive current, but could affect saturation behavior in marginally biased circuits-verify VCE(sat) and switching speed under actual load conditions.
Does BC847CQB-Q require special reflow profile considerations?
Yes. Due to its leadless DFN package with side-wettable flanks, it requires precise stencil aperture design (0.1 mm thickness recommended), controlled peak reflow temperature (≤ 260 °C), and alignment to Nexperia's SOT8015 footprint (1.4 mm × 0.9 mm solder land, 0.34 mm pad width). Misalignment causes solder bridging or insufficient wetting.
