Product details
Overview
BC847CB5000 from Nexperia is an NPN general-purpose bipolar junction transistor in SOT-323 (SC-70) package, with VCEO = 45 V, IC = 100 mA, hFE = 200–450 at IC = 2 mA, and fT = 100 MHz - used for low-power switching and amplification in portable audio bias networks and LED driver stages.
For engineers reviewing the BC847CB5000 datasheet, BC847CB5000 pinout, BC847CB5000 application, or BC847CB5000 equivalent, key selection criteria include DC current gain consistency across production lots, thermal resistance in SOT-323 footprint, saturation voltage at 10 mA drive, and compatibility with 3.3 V logic-level base control.
Technical Context
The BC847CB5000 operates as a medium-speed, low-noise NPN switch with guaranteed hFE binning (B = 200–450), enabling predictable base drive design in discrete amplifier stages and digital interface translators. Its fT of 100 MHz supports stable operation up to audio-band frequencies without phase inversion.
Designed for surface-mount assembly on space-constrained PCBs, it features a maximum RθJA of 375 K/W and a maximum VCE(sat) of 0.3 V at IC = 10 mA and IB = 0.5 mA - critical for minimizing power loss in battery-powered sensor node front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - supports rail voltages up to 36 V with safety margin in industrial I/O modules |
| IC max | 100 mA - sufficient for driving small relays, indicator LEDs, or logic-level shifters |
| hFE | 200–450 at IC = 2 mA - enables precise base resistor calculation for consistent switching thresholds |
| fT | 100 MHz - ensures linear gain retention through 20 kHz audio band with <1 dB roll-off |
| VCE(sat) | 0.3 V max at IC/IB = 10/0.5 mA - reduces conduction loss in always-on bias circuits |
| RθJA | 375 K/W - defines thermal derating slope when mounted on 10 mm² copper pad |
Pinout & Package
SOT-323 (SC-70) plastic surface-mount package with standard 3-pin configuration: emitter, base, collector - optimized for high-density routing and reflow compatibility per IPC-7095.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-impedance return path; determines common-emitter reference point |
| 2 (Base) | Control input | Receives current-limited drive signal; requires series resistor to limit IB to ≤500 µA for safe operation |
| 3 (Collector) | Current source output | Drives load toward VCC; voltage swing limited by VCEO rating and load impedance |
Key Features
| Feature | Design Value |
|---|---|
| hFE binning (B grade) | Guaranteed 200–450 range eliminates need for post-production gain sorting in production test |
| SOT-323 footprint | Enables placement density >120 devices/in² on 4-layer consumer PCBs without thermal vias |
| VCE(sat) ≤ 0.3 V | Reduces power dissipation to <3 mW in 10 mA LED bias applications, extending battery life |
| fT = 100 MHz | Supports clean square-wave edge integrity in 1–5 MHz clock buffer designs without added compensation |
Applications
| Portable Audio Bias Network | LED Driver Stage |
|---|---|
Use Scenario: Setting quiescent current in Class-A headphone amplifier input stage. IC Role / Device Role / Timing Role: Discrete NPN current source providing stable 2 mA bias to op-amp input transistor. Use Value: Tight hFE binning ensures ±5% bias current variation across temperature and unit-to-unit, maintaining THD <0.01%. | Use Scenario: Driving dual-color status LED in BLE-enabled IoT sensor node. IC Role / Device Role / Timing Role: Low-side switch controlling cathode current path for red/green LED pair. Use Value: VCE(sat) ≤ 0.3 V limits LED forward voltage drop impact, preserving 2.8 V minimum supply headroom at 5 mA. |
| Logic-Level Translator | Microcontroller GPIO Expander |
Use Scenario: Converting 1.8 V MCU output to 5 V-compatible signal for legacy peripheral enable line. IC Role / Device Role / Timing Role: Common-emitter inverter with pull-up to 5 V rail and base driven via 10 kΩ resistor. Use Value: fT = 100 MHz ensures <10 ns propagation delay at 100 kHz toggle rate, avoiding timing skew in SPI chip-select paths. | Use Scenario: Adding two extra digital outputs to STM32L4-based environmental monitor using minimal BOM count. IC Role / Device Role / Timing Role: Discrete buffer amplifying weak GPIO signals to drive 10 kΩ pull-up loads on external sensors. Use Value: SOT-323 package allows placement within 2 mm of MCU pins, reducing EMI susceptibility on 3.3 V I/O lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching and amplification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BW | Same hFE bin, but SOT-323W variant with enhanced thermal pad (RθJA = 290 K/W) | Better suited for continuous 50 mA operation in ambient >60°C environments | Select when thermal derating margin is <20% at full IC rating |
| MMBT3904LT1G | hFE = 100–300 (unbinned), fT = 300 MHz, VCEO = 40 V | Higher speed but lower gain consistency; requires tighter base resistor tolerance for same switching threshold | Prefer for RF-coupled preamp stages where bandwidth >50 MHz is required |
Compared with BC847CB5000, BC847BW offers improved thermal performance in sustained-current applications, while MMBT3904LT1G trades gain stability for higher frequency response - making the former ideal for precision biasing and the latter for wideband signal conditioning.

FAQ
Is BC847CB5000 suitable for linear amplification?
Yes - its guaranteed hFE range (200–450) and fT of 100 MHz support stable small-signal amplification up to 20 kHz with <0.5% harmonic distortion at IC = 2 mA. It is commonly used in microphone preamp input stages and sensor signal conditioning where gain predictability matters more than ultra-low noise.
What is the maximum allowable base current for continuous operation?
The absolute maximum base current is 10 mA per datasheet, but for reliable long-term operation at 25°C ambient, IB should be limited to ≤500 µA when IC ≤ 10 mA. This ensures VBE remains within 0.65–0.75 V and prevents gain degradation due to self-heating in the SOT-323 package.
Can BC847CB5000 replace BC847C in existing designs?
Yes - BC847CB5000 is the tape-and-reel packaged version of the BC847C device, sharing identical electrical specifications, pinout, and thermal characteristics. The "B5000" suffix denotes 5,000-unit reel quantity; no layout or schematic changes are required for substitution.
Does BC847CB5000 meet AEC-Q101 requirements?
No - BC847CB5000 is qualified to JEDEC JESD22 standards and rated for industrial temperature range (−65°C to +150°C), but it is not AEC-Q101 qualified. For automotive applications, Nexperia's BC847BQ series (AEC-Q101 qualified, same hFE bin) is the designated alternative.
