Product details
Overview
BC847CQC from Nexperia is an AEC-Q101 qualified NPN general-purpose transistor in a DFN1412D-3 (SOT8009) leadless package, delivering 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 control circuits.
For engineers reviewing the BC847CQC datasheet, BC847CQC pinout, BC847CQC application, or BC847CQC equivalent, this page delivers verified package dimensions, thermal derating curves, AOI-compatible side-wettable flank geometry, and validated automotive-grade performance under 150 °C junction temperature limits.
Technical Context
This transistor operates as a discrete current-controlled switch or linear amplifier with fixed three-terminal topology (base, emitter, collector). Its DFN1412D-3 package enables automated optical inspection via side-wettable flanks and supports reflow soldering on FR4 PCBs with 0.8 mm pitch and 0.48 mm body height.
It meets AEC-Q101 stress qualification for automotive use, with absolute maximum ratings including 45 V VCEO, 6 V VEBO, 200 mA ICM, and 450 mW Ptot on 70 µm copper PCB - enabling robust operation across -55 °C to +150 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown; defines rail compatibility in 24 V automotive and 36 V industrial systems. |
| IC | 100 mA continuous - Sustained collector current capability; suitable for driving LEDs, small relays, and logic-level interface loads. |
| hFE | 420–800 at VCE = 5 V, IC = 2 mA - High DC current gain enables low-base-drive designs, reducing MCU GPIO loading in battery-powered sensors. |
| Ptot | 450 mW on 70 µm FR4 PCB - Thermal limit defining power handling in compact layouts; requires ≤ 278 K/W Rth(j-a) for full-rated operation. |
| VCE(sat) | 400 mV max at IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications. |
| fT | 100 MHz - Transition frequency supporting signal amplification up to audio and low-speed digital edge rates without gain roll-off. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, ultra-thin surface-mount package measuring 1.4 mm × 1.2 mm × 0.48 mm with side-wettable flanks for AOI-compatible solder joint inspection. It features a 0.8 mm pitch and exposes copper terminations on all three sides for thermal and electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires ~0.7 V forward bias and <5 mA drive for full saturation at 100 mA collector load. |
| 2 | Emitter | Reference terminal tied to ground or low-side return path; forms common-emitter configuration with defined current gain and output impedance. |
| 3 | Collector | High-side output node; connects to load supply rail and sinks up to 100 mA while maintaining <400 mV drop in saturation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress test standard - ensures reliability in engine control, lighting, and body modules. |
| Side-wettable flanks (SWF) | Enables automated optical inspection of solder joints without X-ray; eliminates void detection risk in high-volume SMT lines. |
| 0.48 mm package height | Reduces board profile in ultra-thin devices such as wearables, smart sensors, and stacked PCB assemblies. |
| 1.4 mm × 1.2 mm footprint | Occupies 40% less area than SOT23; allows dense placement in multi-channel sensor interfaces and compact power management blocks. |
| 348 K/W Rth(j-a) (35 µm Cu) | Defines thermal bottleneck on minimal PCB copper; guides layout decisions for thermal relief and copper pour sizing. |
Applications
| Automotive LED Tail Light Driver | Industrial Sensor Signal Amplifier |
|---|---|
Use Scenario: Switching 12 V LED arrays in rear lighting modules with PWM dimming. IC Role / Device Role / Timing Role: NPN switch controlling cathode-side current path; handles 80 mA steady-state load with 1 kHz PWM. Use Value: 400 mV VCE(sat) limits power loss to <32 mW, preventing thermal runaway in sealed lamp housings. |
Use Scenario: Amplifying low-level analog output (0–100 mV) from MEMS pressure sensors. IC Role / Device Role / Timing Role: Common-emitter DC amplifier with fixed bias network; provides 20× gain at 10 Hz–1 kHz bandwidth. Use Value: 420–800 hFE ensures stable gain across temperature, reducing calibration drift in factory-set instrumentation. |
| Smart Home Motion Detector Bias Stage | Medical Wearable Battery Monitor Switch |
Use Scenario: Providing active bias current to PIR sensor ICs in ultra-low-power occupancy detectors. IC Role / Device Role / Timing Role: Constant-current source configured with emitter resistor; delivers 2 mA ±5% over -20 °C to +70 °C. Use Value: Tight hFE binning (C-grade) and low VBE tempco (~−2 mV/K) maintain bias stability without trimming. |
Use Scenario: Enabling/disabling fuel gauge IC supply in patch-sized ECG monitors powered by coin cells. IC Role / Device Role / Timing Role: Low-leakage high-side switch isolating 3.3 V rail; off-state ICBO < 15 nA prevents battery drain. Use Value: 6 V VEBO and 50 V VCBO tolerate transient spikes during hot-swap battery insertion. |
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, SOT23 | Same die, but in legacy SOT23-3 package (3.0 mm × 1.4 mm); no side-wettable flanks; Rth(j-a) = 300 K/W. | Lacks AOI support and occupies >2× board area; unsuitable for automotive production lines requiring solder-joint verification. | Select only for prototyping or non-AEC environments where manual inspection suffices and space is not constrained. |
| MMBT3904, SOT23 | hFE = 100–300 (lower gain), VCEO = 40 V, not AEC-Q101 qualified; Ptot = 310 mW. | Lower gain demands higher base drive; reduced voltage margin limits use in 24 V systems with transients. | Acceptable for cost-sensitive consumer IoT nodes where AEC compliance and tight gain tolerance are unnecessary. |
Compared with BC847CQC, the BC847C offers identical silicon performance but inferior manufacturability and thermal density, while MMBT3904 trades gain, voltage headroom, and qualification for lower unit cost in non-automotive contexts.

FAQ
What is the maximum allowable junction temperature for BC847CQC?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent parametric shift or failure. Derating begins at Tamb > 25 °C per Fig. 1, with Ptot dropping to zero at 125 °C on 70 µm copper PCB.
Does BC847CQC support reflow soldering with standard lead-free profiles?
Yes - the DFN1412D-3 package is qualified for JEDEC J-STD-020-compliant lead-free reflow. Recommended peak temperature is 260 °C, with 60–150 s above 217 °C. Fig. 17 provides exact stencil and land pattern dimensions for reliable wetting of side-wettable flanks.
How does the hFE variation affect bias design in linear amplifier configurations?
With hFE = 420–800 at IC = 2 mA, base current must be designed for worst-case minimum gain (420) to ensure saturation or intended operating point. For precision DC amplifiers, emitter degeneration or feedback is recommended to reduce sensitivity to hFE spread.
Is BC847CQC pin-compatible with other BC847x variants in the same package?
Yes - all BC847xQC types (A/B/C) share identical DFN1412D-3 pinout (B-E-C), marking codes, and mechanical footprint. Only hFE binning differs; substitution requires verifying gain requirements and thermal margins for the target application.
