Product details
Overview
BC847CW,115 from Nexperia is a high-gain NPN general-purpose transistor in SOT323 (SC-70) package, rated for 45 V VCEO, 100 mA IC, and hFE = 420–800 at VCE = 5 V / IC = 2 mA. It serves as a low-power switching and linear amplification device in compact consumer and industrial signal-path circuits.
For engineers reviewing the BC847CW,115 datasheet, BC847CW,115 pinout, BC847CW,115 application, or BC847CW,115 equivalent, key selection criteria include its guaranteed high DC current gain band, SOT323 thermal performance (Rth(j-a) = 625 K/W), low VCE(sat) (200 mV typ. at IC = 100 mA / IB = 5 mA), and JEITA-registered SC-70 footprint compatibility.
Technical Context
This transistor operates in active and saturation regions with defined breakdown limits: VCBO = 50 V, VCEO = 45 V, and VEBO = 6 V. Its hFE is specified under tightly controlled conditions (VCE = 5 V, IC = 2 mA), ensuring predictable biasing in low-current amplifier stages.
Thermal behavior follows IEC 60134 absolute maximum ratings, with Tj ≤ 150 °C and Ptot = 200 mW on FR4 PCB. Transient thermal impedance data supports pulsed operation up to 1 ms with ICM = 200 mA, enabling reliable use in intermittent switching loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in low-voltage switch designs. |
| IC | 100 mA continuous - Absolute max DC collector current; sets load-driving capability in signal-level interfaces. |
| hFE | 420–800 at VCE = 5 V, IC = 2 mA - Tight high-gain bin ensures stable bias point in amplifier feedback networks. |
| VCE(sat) | 200 mV typical at IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes power loss and heating in digital switch applications. |
| Rth(j-a) | 625 K/W - Junction-to-ambient thermal resistance on standard FR4 PCB; informs derating above 25 °C ambient. |
| fT | 100 MHz - Transition frequency at VCE = 5 V, IC = 10 mA; supports audio-frequency and low-MHz signal amplification. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.75 mm footprint, 0.95 mm height, 3-terminal leadframe with gull-wing terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires series resistor to limit IB and ensure saturation or linear operation. |
| 2 | Emitter (E) | Common reference terminal; connected to ground or low-side return path in common-emitter configurations. |
| 3 | Collector (C) | Output current sink; ties to load or pull-up resistor; voltage swing limited by VCEO rating. |
Key Features
| Feature | Design Value |
|---|---|
| High hFE bin (420–800) | Reduces required base drive current by >2× vs. standard BC847W, lowering MCU GPIO loading in discrete logic interfaces. |
| SOT323 (SC-70) package | Enables <1.8 mm² board area usage-critical for space-constrained wearables and sensor nodes. |
| VCE(sat) ≤ 400 mV (max) | Ensures <0.5% power loss at 100 mA load, supporting thermally sensitive battery-powered designs. |
| JEITA-registered marking "1G" | Enables automated optical inspection (AOI) traceability and eliminates ambiguity in SMT line verification. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Driving single-color indicator LEDs from 3.3 V or 5 V microcontroller outputs. IC Role / Device Role / Timing Role: NPN switch controlling LED anode/cathode current path with fixed base resistor. Use Value: Guaranteed hFE ≥ 420 ensures full saturation at IB < 0.25 mA, preserving MCU drive strength for multiple parallel loads. |
Use Scenario: Level-shifting and current boosting for legacy 5 V peripherals interfaced to 3.3 V MCUs. IC Role / Device Role / Timing Role: Active-low buffer translating logic states while sourcing/sinking >10 mA per channel. Use Value: Low VCE(sat) (<400 mV) maintains clean logic-low levels even under 10 mA load, preventing false triggering. |
| Audio Pre-amplifier Stage | Power Supply Enable Switch |
|
Use Scenario: Low-noise small-signal amplification of electret microphone output before ADC sampling. IC Role / Device Role / Timing Role: Common-emitter amplifier biased in linear region with emitter degeneration. Use Value: fT = 100 MHz and NF = 2–10 dB support 20 kHz bandwidth with minimal added noise in portable audio paths. |
Use Scenario: Enabling/disabling auxiliary 3.3 V or 5 V rails in multi-rail embedded systems via MCU control. IC Role / Device Role / Timing Role: High-side or low-side pass transistor activated by GPIO-driven base. Use Value: 45 V VCEO headroom allows safe operation across varied input rails; 100 mA rating covers most LDO enable currents. |
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 | hFE = 200–450 (lower gain band); identical package and voltage/current ratings. | Less suitable for ultra-low-base-drive scenarios but more tolerant of wide IC variation. | Select when circuit bias stability over temperature is prioritized over minimum IB. |
| MMBT3904LT1G | hFE = 100–300; SOT-23 package (larger footprint); same VCEO/IC specs. | Requires PCB redesign due to different pad layout; higher Rth(j-a) (~500 K/W) limits power density. | Choose only if SOT-23 is already standardized in production and gain tolerance >300 is acceptable. |
Compared with BC847BW,115 and MMBT3904LT1G, BC847CW,115 delivers the highest guaranteed hFE in the smallest footprint, making it optimal for miniaturized, low-IB designs where gain consistency directly impacts system margin and power efficiency.

FAQ
What is the maximum allowable junction temperature for BC847CW,115?
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 is required above 25 °C ambient using Rth(j-a) = 625 K/W on standard FR4 PCB.
Does BC847CW,115 support automotive applications?
No. Per Nexperia's revision history (Rev. 13, July 2022), BC847CW,115 is explicitly non-automotive qualified. It lacks AEC-Q101 stress testing and is not warranted for safety-critical or life-support systems. Automotive alternatives must be selected from Nexperia's -Q qualified portfolio.
How does the "1G" marking code correlate to BC847CW,115?
"1G" is the JEITA-standard top-side laser marking for BC847CW in SOT323 packages, where "1" denotes the BC847 family and "G" identifies the CW gain group. The trailing % symbol is a placeholder for manufacturing site code and is replaced with actual location identifiers during production.
Can BC847CW,115 replace BC847C in through-hole designs?
No. BC847CW,115 uses SOT323 (SC-70) surface-mount packaging, while BC847C uses TO-92 through-hole packaging. Mechanical, thermal, and soldering requirements differ fundamentally. Direct replacement requires full PCB redesign and revalidation of thermal and electrical performance.
