Product details
Overview
BC847CQC-QZ from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in a leadless DFN1412D-3 (SOT8009) 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 control modules, sensor interface stages, and low-power logic-level translation circuits.
For engineers reviewing the BC847CQC-QZ datasheet, BC847CQC-QZ pinout, BC847CQC-QZ application, or BC847CQC-QZ equivalent, this page provides verified package dimensions, thermal derating curves, side-wettable flank solder joint validation data, and automotive-grade qualification evidence - all critical for AOI-compatible PCB layout and AEC-compliant BOM selection.
Technical Context
This transistor operates as a silicon NPN bipolar junction device with base-controlled current amplification, optimized for stable DC gain across −55 °C to 150 °C ambient range and low VCE(sat) (≤400 mV at IC = 100 mA / IB = 5 mA). Its DFN1412D-3 package integrates side-wettable flanks for automated optical inspection of solder joints and supports reflow profiles compliant with IPC-J-STD-020.
The device meets Absolute Maximum Ratings per IEC 60134, including 45 V VCEO, 6 V VEBO, and 360 mW Ptot on 35 µm FR4 copper. Thermal resistance Rth(j-a) is 348 K/W (standard footprint), enabling operation up to 150 °C junction temperature without forced cooling in thermally managed automotive subassemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with safety margin. |
| IC | 100 mA continuous - Sustained collector current rating; suitable for driving small relays, LEDs, or logic-level MOSFET gates. |
| hFE | 420–800 at VCE = 5 V, IC = 2 mA - High DC current gain ensures low base drive requirements in linear amplification and saturated switch modes. |
| 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 applications. |
| Package | DFN1412D-3 (SOT8009) - 1.4 mm × 1.2 mm × 0.48 mm body with side-wettable flanks; supports AOI and fits 1.3 mm × 0.45 mm reflow footprint. |
| AEC-Q101 | Qualified - Certified for automotive discrete semiconductor stress testing; valid for under-hood and cabin control unit deployment. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, ultra-thin surface-mount package with side-wettable flanks for solder joint inspection. Dimensions: 1.4 mm × 1.2 mm × 0.48 mm body height; 0.8 mm pitch; 0.02 mm max flank protrusion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires ≤5 mA base drive for full saturation at 100 mA collector load. |
| 2 | Emitter (E) | Reference terminal for biasing; internally connected to exposed thermal pad in DFN layout for enhanced heat dissipation. |
| 3 | Collector (C) | High-side output node; rated for 45 V blocking and 200 mA peak pulsed current (tp ≤ 1 ms). |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables 100% automated optical inspection (AOI) of solder fillets on production lines without X-ray. |
| Ultra-small footprint | 1.4 mm × 1.2 mm area - reduces PCB real estate by >50% vs. SOT23 while maintaining thermal performance. |
| Low profile | 0.48 mm max body height - allows stacking under shields or integration into ultra-thin modules (e.g., door latch ECUs). |
| AEC-Q101 qualification | Validated for automotive temperature cycling, humidity, and mechanical shock - eliminates need for additional qualification testing. |
Applications
| Automotive Door Module Switching | Industrial Sensor Signal Conditioning |
|---|---|

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,315 (Nexperia) | SOT23 package; no side-wettable flanks; same hFE range but 1.3 mm height and larger footprint. | Lacks AOI support; unsuitable for automotive high-reliability SMT lines requiring solder joint verification. | Select when cost sensitivity outweighs AOI requirement and board space permits SOT23. |
| MMBT3904LT1G (onsemi) | SOT23-3; 40 V VCEO; hFE 100–300; not AEC-Q101 qualified; higher VCE(sat) (300 mV typ). | Not approved for automotive use; limited to consumer/industrial applications with lower voltage margins. | Choose only for non-automotive designs where 45 V margin and AEC compliance are unnecessary. |
Compared with BC847C,315 and MMBT3904LT1G, BC847CQC-QZ uniquely combines AEC-Q101 qualification, side-wettable flanks for AOI, and 45 V/100 mA ratings in a 0.48 mm profile - making it the sole option for space-constrained, high-volume automotive PCBs requiring zero-defect solder joint assurance.

FAQ
What is the maximum allowable junction temperature for BC847CQC-QZ?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent degradation of hFE and VCE(sat). Derating is required above 25 °C ambient: Ptot drops linearly to 0 mW at 150 °C for 35 µm FR4 copper (348 K/W Rth(j-a)).
Does BC847CQC-QZ require special reflow profile considerations?
Yes - its DFN1412D-3 package uses side-wettable flanks designed for standard lead-free reflow (J-STD-020 Class 3). Recommended stencil thickness is 0.1 mm, and solder land dimensions are 0.45 mm × 0.8 mm per flank. Peak temperature must not exceed 260 °C for ≤30 seconds to avoid delamination.
How does the hFE variation affect circuit design?
hFE spans 420–800 at IC = 2 mA, so base resistor design must ensure saturation across the full range. For 100 mA IC, minimum IB = 100 mA / 420 ≈ 238 µA; typical design uses ≥500 µA to guarantee VCE(sat) ≤400 mV even at low hFE and high temperature.
Is BC847CQC-QZ pin-compatible with other BC847 variants?
No - BC847CQC-QZ uses DFN1412D-3 (SOT8009) with bottom-terminal layout (1-B, 2-E, 3-C), whereas BC847C,315 uses SOT23 (top-view: 1-E, 2-B, 3-C). Footprint, soldering method, and thermal path differ fundamentally; direct replacement requires PCB redesign and AOI program updates.
