Product details
Overview
BC847CQBZ from Nexperia is an AEC-Q101 qualified NPN general-purpose transistor in a leadless DFN1110D-3 (SOT8015) package, delivering 45 V VCEO, 100 mA IC, and hFE of 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 BC847CQBZ datasheet, BC847CQBZ pinout, BC847CQBZ application, or BC847CQBZ equivalent, this part supports AOI-compatible solder joint inspection, operates up to 150 °C junction temperature, and provides side-wettable flanks for reliable reflow process control in high-volume SMT assembly.
Technical Context
This transistor employs a planar epitaxial silicon structure optimized for stable DC current gain across temperature (−55 °C to +150 °C) and low VCE(sat) (max 400 mV at IC = 100 mA / IB = 5 mA). Its DFN1110D-3 package integrates side-wettable flanks to enable automated optical inspection of solder fillets without X-ray.
The device meets AEC-Q101 stress test requirements for discrete semiconductors, with absolute maximum ratings including 50 V VCBO, 6 V VEBO, and 420 mW Ptot on 70 µm copper FR4 - confirming suitability for under-hood automotive modules and industrial control logic stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; enables use in 36 V automotive supply rails with margin. |
| IC | 100 mA continuous - Supports driving small relays, LEDs, or logic-level interface loads without external heat sinking. |
| hFE | 420–800 @ VCE=5 V, IC=2 mA - High DC gain ensures low base drive current in linear amplification or saturated switch modes. |
| VCE(sat) | ≤400 mV @ IC=100 mA, IB=5 mA - Minimizes power loss and self-heating in high-duty-cycle switching applications. |
| Ptot | 420 mW @ Tamb ≤25 °C on 70 µm Cu FR4 - Defines thermal derating envelope for board-level power handling. |
| Tj(max) | 150 °C - Enables operation in under-dash automotive environments and sealed industrial enclosures. |
Pinout & Package
BC847CQBZ uses the DFN1110D-3 (SOT8015) ultra-thin leadless package: 1.1 × 1.0 × 0.48 mm body, 0.65 mm pitch, side-wettable flanks, and 0.5 mm max height - optimized for AOI and high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input terminal; requires ~2.2 kΩ pull-up for standard 5 V TTL-compatible switching. |
| 2 | Emitter (E) | Reference node for current flow; connected to GND or low-side return path in common-emitter configurations. |
| 3 | Collector (C) | Output current sink terminal; rated for 45 V and 100 mA continuous load switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22. |
| Side-wettable flanks | Enables 100% automated optical inspection of solder joints without X-ray, reducing post-reflow defect escape. |
| Ultra-small footprint | 1.1 × 1.0 mm area - saves >60% board space vs. SOT23 while maintaining comparable thermal performance. |
| Low profile (0.48 mm) | Supports conformal coating and mechanical stacking in ultra-thin modules such as ADAS sensor housings. |
| High hFE bin (C) | Guaranteed 420–800 gain range reduces base drive circuit complexity and improves saturation consistency. |

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 |
|---|---|---|---|
| BC847BW,115 (Nexperia) | SOT323 package (3.0 × 1.4 × 1.1 mm); no side-wettable flanks; hFE 420–800 same bin. | Larger footprint and taller profile; unsuitable for AOI-dependent automotive production. | Select when legacy SMT lines lack AOI capability or board layout permits larger package. |
| MMBT4401LT1G (ON Semiconductor) | SOT-23 package; VCEO = 40 V; hFE = 100–300 @ IC = 10 mA; not AEC-Q101 qualified. | Lower voltage rating and gain; limited to non-automotive industrial or consumer use. | Choose only for cost-sensitive, non-automotive applications where 40 V margin suffices and qualification is unnecessary. |
Compared with BC847BW,115 and MMBT4401LT1G, BC847CQBZ uniquely combines AEC-Q101 compliance, side-wettable flanks for AOI, and ultra-compact DFN1110D-3 packaging - making it the only option qualified for next-generation automotive electronics with zero-defect SMT requirements.

FAQ
Is BC847CQBZ pin-compatible with BC847C, BC847CW, or BC847BW?
No - BC847CQBZ uses the DFN1110D-3 (SOT8015) leadless package with side-wettable flanks, while BC847C (SOT323), BC847CW (SC-70), and BC847BW (SOT323) use leaded packages with different pinouts and thermal footprints. Direct replacement requires PCB redesign and requalification.
What is the maximum allowable PCB copper thickness for achieving full 420 mW power dissipation?
Full 420 mW Ptot is specified only when mounted on FR4 with single-sided 70 µm copper, tin-plated, and standard footprint. With 35 µm copper, Ptot drops to 340 mW. Thicker copper (≥70 µm) does not further increase rating - thermal resistance is defined for standardized conditions.
Does BC847CQBZ support reflow soldering per JEDEC J-STD-020?
Yes - the DFN1110D-3 package is qualified for lead-free reflow per JEDEC J-STD-020D. Recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates and soak profiles matching standard Pb-free profiles for ultra-thin small-outline packages.
Can BC847CQBZ be used in linear amplifier configurations?
Yes - its hFE stability (420–800 over IC = 0.1–10 mA), low noise figure (10 dB @ 1 kHz), and predictable VBE behavior (580–700 mV @ IC = 2 mA) support Class-A small-signal amplification in sensor front-ends and audio preamp stages within its 45 V/100 mA operating limits.
