Product details
Overview
BC847AQC from Nexperia is an AEC-Q101 qualified NPN general-purpose transistor in a DFN1412D-3 (SOT8009) leadless package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 110–220 at VCE = 5 V and IC = 2 mA. It delivers low saturation voltage (VCEsat ≤ 400 mV at IC = 100 mA, IB = 5 mA), operates across −55 °C to +150 °C, and targets space-constrained automotive and industrial signal switching.
For engineers reviewing the BC847AQC datasheet, BC847AQC pinout, BC847AQC application, or BC847AQC equivalent, key selection criteria include its side-wettable flank (SWF) footprint for AOI-compatible reflow, ultra-small 1.4 mm × 1.2 mm × 0.48 mm body, AEC-Q101 qualification, and hFE binning consistency within the BC847xQC series.
Technical Context
This discrete NPN transistor functions as a low-voltage, medium-current switch or small-signal amplifier with fixed-emitter bias topology. Its design emphasizes thermal robustness via low Rth(j-a) (278 K/W on 70 µm FR4 PCB) and stable hFE over temperature (−55 °C to +150 °C).
The device uses silicon planar epitaxial technology with optimized base doping and emitter geometry to achieve tight hFE distribution (110–220 for BC847AQC), low VBE (580–700 mV at VCE = 5 V, IC = 2 mA), and high fT (100 MHz at VCE = 5 V, IC = 10 mA), supporting reliable operation in digital logic interfacing and analog amplification stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines safe operating range in switching applications. |
| IC | 100 mA - Continuous DC collector current rating; supports load switching up to ~100 mA without derating at Tamb ≤ 25 °C. |
| hFE | 110–220 - DC current gain at VCE = 5 V, IC = 2 mA; enables predictable base drive sizing for saturated switching. |
| VCEsat | ≤ 400 mV - Collector-emitter saturation voltage at IC = 100 mA, IB = 5 mA; ensures low conduction loss in power-efficient on-state operation. |
| Ptot | 450 mW - Total power dissipation on FR4 PCB with 70 µm copper; sets thermal limits for continuous operation in compact layouts. |

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 automated optical inspection (AOI) of solder joints. Its low profile (0.5 mm height) and 0.8 mm pitch support high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Controls minority carrier injection into the base region; requires precise current limiting (e.g., 5 mA typical for 100 mA IC) to ensure saturation. |
| 2 | Emitter (E) | Common reference terminal for NPN configuration; internally connected to substrate; must be tied to lowest potential in switching circuits. |
| 3 | Collector (C) | Output current path; handles full load current (up to 100 mA DC); thermally coupled to exposed die pad in DFN package for improved heat transfer. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-enables use in non-safety-critical vehicle subsystems without additional qualification. |
| Side-wettable flanks (SWF) | Enables automated optical inspection of solder fillets on all three terminals-reduces post-reflow defect escapes in high-volume SMT lines. |
| Ultra-small footprint | 1.4 mm × 1.2 mm area-saves >50% board space vs. conventional SOT23 packages, critical for wearables and sensor modules. |
| Low package height | 0.48 mm body thickness-facilitates stacking with other ultra-low-profile components and meets strict mechanical clearance requirements in slim enclosures. |
| High power dissipation | 450 mW on 70 µm FR4 PCB-supports higher current density than standard SOT23 equivalents without external heatsinking. |
Applications

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 | SOT323 package (2.1 mm × 1.25 mm × 0.95 mm); no side-wettable flanks; hFE 110–220 same bin; Ptot = 310 mW. | Lacks AOI support; larger footprint and height; lower power handling; not AEC-Q101 qualified. | Select when cost or legacy footprint compatibility outweighs AOI capability and automotive compliance. |
| BC846AQC | Same DFN1412D-3 package and AEC-Q101 qualification; lower VCEO = 65 V; identical hFE range; same pinout. | Higher voltage rating increases safety margin in 24 V industrial systems but offers no benefit in 12 V automotive use. | Prefer only if system-level transient protection requires >45 V standoff; otherwise BC847AQC provides optimal cost/performance balance. |
Compared with BC847BW, BC847AQC delivers superior manufacturability (SWF + AOI), higher power handling (+45%), and automotive qualification-making it the preferred choice for new designs targeting volume production and reliability. Versus BC846AQC, BC847AQC's 45 V rating better matches typical 12 V automotive rail requirements while reducing unnecessary voltage overhead.

FAQ
What is the maximum allowable junction temperature for BC847AQC?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent degradation of hFE, increased leakage, or bond wire failure. Thermal design must ensure Tj remains below 150 °C under worst-case ambient and power dissipation conditions, using the specified Rth(j-a) values (278 K/W on 70 µm FR4 PCB).
Does BC847AQC support automatic optical inspection (AOI)?
Yes-BC847AQC uses the DFN1412D-3 (SOT8009) package with side-wettable flanks (SWF), enabling high-contrast imaging of solder fillets during AOI. This feature is explicitly cited in the "Features and benefits" section and validated per IPC-A-610 Class 2/3 standards for leadless packages, ensuring reliable detection of insufficient solder, bridging, or misalignment.
How does the hFE binning of BC847AQC compare to BC847BQC and BC847CQC?
BC847AQC has hFE = 110–220, BC847BQC = 200–450, and BC847CQC = 420–800-all measured at VCE = 5 V and IC = 2 mA. The A-bin provides moderate, tightly controlled gain ideal for predictable base drive in switching applications, while B- and C-bins offer higher gain for low-input-current amplification. All share identical package, voltage/current ratings, and AEC-Q101 qualification.
Can BC847AQC replace BC847A in existing SOT23 designs?
No-BC847AQC uses DFN1412D-3 (SOT8009), a 3-terminal leadless package with 0.8 mm pitch and side-wettable flanks, whereas BC847A uses SOT23 with gull-wing leads and 0.95 mm pitch. Footprint, soldering profile, and rework methodology differ significantly. Migration requires PCB layout revision, stencil redesign, and AOI program updates-not a drop-in replacement.
