Product details
Overview
BC847CT,115 from Nexperia is an NPN general-purpose bipolar junction transistor (BJT) in SOT416 (SC-75) surface-mount plastic package, rated for 45 V VCEO, 100 mA IC, and hFE group C (420–800 at IC = 2 mA, VCE = 5 V). It serves as a low-voltage switching or small-signal amplification device in space-constrained consumer and automotive control circuits.
For engineers reviewing the BC847CT,115 datasheet, BC847CT,115 pinout, BC847CT,115 application, or BC847CT,115 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (Rth(j-a) = 833 K/W), saturation voltage (VCEsat ≤ 400 mV at IC = 100 mA), and exact SOT416 terminal mapping - all confirmed per Nexperia's BC847_SER Rev. 9 datasheet.
Technical Context
The BC847CT,115 operates as a discrete NPN BJT with fixed gain grouping (C-grade), optimized for linear amplification and saturated switching in low-power analog and digital interface stages. Its base-emitter voltage (VBE = 580–700 mV at IC = 2 mA) and transition frequency (fT = 100 MHz) support stable operation up to mid-frequency signal conditioning.
Designed for FR4 PCB mounting with standard footprint, it exhibits VCEO = 45 V, VCB0 = 50 V, and ESD robustness per HBM Class 2 (≥2 kV), with thermal resistance Rth(j-a) = 833 K/W confirming suitability for thermally isolated layouts in compact modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; defines safe operating range in 24 V and lower supply rails. |
| IC | 100 mA - Continuous collector current rating; supports load switching up to ~100 mA with adequate heatsinking. |
| hFE (Group C) | 420–800 - High DC current gain at IC = 2 mA, enabling low-base-drive switching in microcontroller GPIO interfaces. |
| VCEsat | ≤ 400 mV at IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes power loss and self-heating in on-state switching. |
| fT | 100 MHz - Transition frequency confirms usable bandwidth for audio and low-speed digital signal buffering. |
| Rth(j-a) | 833 K/W - Thermal resistance in free air; requires careful PCB copper area planning for sustained >50 mA operation. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical stress testing. |
Pinout & Package
SOT416 (SC-75) ultra-small plastic surface-mount package: 3-terminal, lead-free, body size 1.75 × 1.45 × 0.9 mm, designed for high-density routing and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires ~5 mA base drive for full saturation at 100 mA collector load. |
| 2 | Emiter | Reference terminal tied to ground or common emitter node; forms return path for base and collector currents. |
| 3 | Collector | Output current sink node; connects to load (e.g., LED, relay coil, logic gate input) referenced to positive supply. |
Key Features
| Feature | Design Value |
|---|---|
| NPN general-purpose BJT | Enables both linear amplification (e.g., sensor signal boosting) and digital switching (e.g., MCU-driven LED control) with single device type. |
| hFE Group C selection | Guarantees minimum DC gain of 420 at 2 mA, reducing base resistor tolerance sensitivity in production designs. |
| AEC-Q101 qualification | Validates reliability for under-hood automotive modules, including engine control sensors and body electronics. |
| SOT416 (SC-75) package | Reduces PCB footprint by ~40% vs. SOT23 while maintaining compatible solder profile and pick-and-place compatibility. |
| VEB0 = 6 V rating | Permits safe reverse-bias operation in level-shifting or bidirectional interface applications without emitter-base junction damage. |
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,115 | SOT323 (SC-70) package; Rth(j-a) = 625 K/W; same hFE group B (200–450), not group C. | Higher thermal resistance than BC847CT,115; suitable where board space allows larger footprint but gain tolerance is less critical. | Select BC847BW,115 only if SOT323 footprint is already standardized and gain spread ≥200 is acceptable. |
| BC847CM,115 | SOT883 (SC-101) package; 1.0 × 0.6 × 0.5 mm; Rth(j-a) = 500 K/W; identical hFE group C spec. | Smaller footprint than BC847CT,115 but higher assembly complexity; better thermal performance due to lower Rth(j-a). | Choose BC847CM,115 when ultra-miniaturization is mandatory and reflow process supports 0201-class placement. |
Compared with BC847CT,115, BC847BW,115 trades thermal efficiency for easier handling and slightly looser gain control, while BC847CM,115 improves thermal dissipation and reduces area at the cost of tighter placement tolerances and higher process risk.

FAQ
What is the maximum collector-emitter voltage rating for BC847CT,115?
The BC847CT,115 has a maximum collector-emitter voltage (VCEO) rating of 45 V under open-base conditions. This rating is absolute maximum and must not be exceeded in circuit design; derating is recommended for long-term reliability in automotive environments with load dump transients. The BC847CT,115 datasheet specifies this value in Table 6 (Limiting Values) and confirms it applies specifically to the SOT416 variant.
Is BC847CT,115 qualified for automotive applications?
Yes, BC847CT,115 is AEC-Q101 qualified per Nexperia's BC847_SER Rev. 9 datasheet Section 8.1. This certification covers stress tests including temperature cycling, high-temperature operating life, and ESD robustness, making BC847CT,115 suitable for non-safety-critical automotive systems such as door modules, lighting controls, and HVAC actuators.
What package type does BC847CT,115 use, and what are its key mechanical dimensions?
BC847CT,115 uses the SOT416 (SC-75) surface-mount plastic package, with body dimensions of 1.75 mm × 1.45 mm × 0.9 mm and 0.9 mm lead pitch. Figure 15 in the BC847_SER datasheet provides full outline drawings and solder land recommendations, confirming compatibility with standard reflow profiles for fine-pitch SMT assembly.
What is the DC current gain (hFE) range for BC847CT,115, and at what test conditions is it specified?
The BC847CT,115 is hFE Group C, with guaranteed DC current gain of 420–800 at VCE = 5 V and IC = 2 mA (Table 2 and Table 8). At IC = 10 µA, typical hFE is 420. This gain band is explicitly assigned to the "CT" suffix in Table 1 and validated across temperature per Figures 9–12 in the BC847_SER datasheet.
How does the thermal resistance of BC847CT,115 compare to other BC847 variants?
BC847CT,115 has a junction-to-ambient thermal resistance (Rth(j-a)) of 833 K/W in free air on FR4 PCB (Table 7), higher than BC847C (500 K/W, SOT23) and BC847CM (500 K/W, SOT883) but lower than BC847CW (625 K/W, SOT323). This reflects the SOT416's smaller copper exposure area, requiring careful thermal layout for continuous >50 mA operation.
