Product details
Overview
BC848W,115 from Nexperia is an NPN general-purpose bipolar junction transistor in SOT323 (SC-70) surface-mount package, rated for 30 V VCEO, 100 mA IC, and DC current gain (hFE) of 110–800 at IC = 2 mA, VCE = 5 V; used in low-voltage switching and small-signal amplification circuits on space-constrained PCBs.
For engineers reviewing the BC848W,115 datasheet, BC848W,115 pinout, BC848W,115 application, or BC848W,115 equivalent, this page delivers verified electrical parameters, thermal limits, package dimensions, pin mapping, and real-world use cases - all aligned with Nexperia's Rev. 07 (2009) product data sheet.
Technical Context
The BC848W operates as a standard NPN BJT with base-controlled current amplification, supporting linear amplification and saturated switching modes. Its hFE range (110–800) enables design flexibility across biasing configurations, while VCE(sat) ≤ 250 mV at IC = 10 mA / IB = 0.5 mA ensures low-loss switching in digital logic interfaces.
Thermal resistance Rth(j-a) is 625 K/W on FR4 PCB, limiting continuous power dissipation to 200 mW at Tamb ≤ 25 °C. Cutoff frequencies (fT ≥ 100 MHz) and low Cc (2.5 pF typ.) support audio and low-speed RF signal handling up to ~10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - Maximum collector-emitter voltage before breakdown; defines safe operating voltage in low-voltage logic and sensor interface circuits. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, relays, and small MOSFET gates without external heat sinking. |
| hFE | 110–800 - DC current gain at VCE = 5 V, IC = 2 mA; supports wide-range bias stability in amplifier stages and predictable saturation in switch designs. |
| VCE(sat) | 90–250 mV - Collector-emitter saturation voltage at IC = 10 mA / IB = 0.5 mA; ensures <100 mW power loss per switch event in digital output buffers. |
| Ptot | 200 mW - Total power dissipation on FR4 PCB; sets thermal derating limit for ambient temperatures above 25 °C in compact consumer electronics layouts. |
| fT | ≥100 MHz - Transition frequency at VCE = 5 V, IC = 10 mA; enables stable small-signal amplification in audio preamps and oscillator feedback paths. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 2.2 mm footprint, 0.95 mm height, three-terminal configuration optimized for high-density routing and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires series resistor (typically 1–10 kΩ) to limit IB and ensure reliable saturation or linear operation. |
| 2 | Emitter | Common reference terminal; connected to ground or low-side return path; establishes current sink capability for load switching. |
| 3 | Collector | Output current terminal; connects to load (e.g., LED anode, relay coil) and supply rail; handles full IC up to 100 mA in DC mode. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOT323 package | Enables placement in <2.5 mm board spacing zones; compatible with standard 0.5 mm pitch reflow footprints per Nexperia MSA429 spec. |
| Wide hFE spread (110–800) | Reduces need for binning in production; allows single BOM part to cover both high-gain amplifiers and robust-switching applications. |
| Low VCE(sat) (≤250 mV) | Minimizes conduction loss in battery-powered systems; extends runtime in portable devices using 3.3 V or 5 V rails. |
| 150 °C max junction temperature | Supports operation in automotive under-hood modules and industrial enclosures with limited airflow and elevated ambient temps. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Driving discrete indicator LEDs from 3.3 V MCU outputs with current limiting via base resistor. IC Role / Device Role / Timing Role: NPN switch configured in common-emitter topology, sinking LED cathode current to ground. Use Value: VCE(sat) ≤ 250 mV ensures >95% efficiency at 20 mA LED current; SOT323 footprint fits tight spacing near MCU QFN packages. |
Use Scenario: Level-shifting and current boosting for legacy 5 V peripherals connected to modern 3.3 V microcontrollers. IC Role / Device Role / Timing Role: Digital buffer stage translating logic-high signals while sourcing/sinking >10 mA per channel. Use Value: hFE ≥ 110 guarantees full saturation with 3.3 V GPIO drive; 100 mA IC rating supports multiple parallel loads. |
| Audio Pre-amplifier Stage | Power Supply Enable Switch |
|
Use Scenario: Low-noise voltage amplification of electret microphone output prior to ADC sampling. IC Role / Device Role / Timing Role: Common-emitter small-signal amplifier biased in active region with emitter degeneration. Use Value: NF = 2–10 dB at 1 kHz enables SNR >60 dB in voice-band front-ends; fT ≥ 100 MHz avoids bandwidth limitation. |
Use Scenario: Controlled turn-on of auxiliary 12 V rail in embedded system power sequencing. IC Role / Device Role / Timing Role: High-side or low-side enable switch controlling PMOS gate or relay coil activation. Use Value: 30 V VCEO safely isolates control logic from 12 V domain; 200 mW Ptot accommodates brief inrush during rail startup. |
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 |
|---|---|---|---|
| BC847W,115 | hFE = 200–450 (narrower range), same VCEO/IC/package | Better gain consistency for precision biasing; less margin for worst-case β variation | Select when circuit requires tighter hFE tolerance and reduced test screening overhead. |
| MMBT3904LT1G | VCEO = 40 V, hFE = 100–300, SOT-23 package (larger footprint) | Higher voltage headroom but 0.5 mm larger body; incompatible with SC-70 land patterns | Choose only if board layout allows SOT-23 and system requires >30 V blocking capability. |
Compared with BC848W,115, BC847W,115 offers tighter hFE control for stable biasing, while MMBT3904LT1G provides higher VCEO at the cost of package incompatibility - making BC848W optimal for space-constrained 30 V switching where gain variability is acceptable.

FAQ
What is the maximum allowable base current for BC848W,115?
The peak base current (IBM) is rated at 200 mA for single pulses ≤1 ms. For continuous DC operation, base current must be limited to maintain IC ≤ 100 mA and junction temperature ≤ 150 °C. Typical design uses IB = IC/10 to 20 for guaranteed saturation, e.g., 5–10 mA for 100 mA collector load.
Can BC848W,115 replace BC848B in existing SOT23 designs?
No - BC848W uses SOT323 (SC-70) package (1.35 × 2.2 mm), while BC848B uses SOT23 (TO-236AB) (2.9 × 1.3 mm). Footprint, solder pad layout, and thermal resistance differ significantly. Mechanical redesign and requalification are required for substitution.
What is the typical noise figure of BC848W,115 in small-signal amplification?
The noise figure is 2–10 dB at VCE = 5 V, IC = 200 μA, RS = 2 kΩ, f = 1 kHz, and B = 200 Hz. This makes it suitable for low-frequency audio pre-amplification where SNR >60 dB is required, but not for RF or high-fidelity analog stages demanding sub-1 dB NF.
Does BC848W,115 have qualified automotive grade variants?
No - BC848W,115 is rated for −65 °C to +150 °C operating/storage temperature and meets industrial reliability standards, but it is not AEC-Q101 qualified. For automotive applications, Nexperia offers the BC848BW-Q series, which includes extended qualification testing and traceability.
