Product details
Overview
BC847BWE6433HTMA1 from Nexperia is an NPN silicon general-purpose bipolar junction transistor (BJT) designed for audio-frequency input stages and driver circuits. It delivers hFE = 200–450 at IC = 2 mA, VCE = 5 V; VCEO = 45 V; VCE(sat) ≤ 200 mV at IC = 10 mA, IB = 0.5 mA; and fT = 250 MHz - enabling low-noise amplification in portable audio preamps and logic-level interface drivers.
For engineers reviewing the BC847BWE6433HTMA1 datasheet, BC847BWE6433HTMA1 pinout, BC847BWE6433HTMA1 application, or BC847BWE6433HTMA1 equivalent, key selection criteria include DC current gain grouping (hFE-B), SOT323 package thermal resistance (RthJS ≤ 90 K/W), AEC-Q101 qualification, and low-noise performance (F = 1.2–4 dB at 1 kHz).
Technical Context
This transistor operates as a linear amplifier or saturated switch in low-voltage analog and digital interface circuits. Its hFE grouping (B: 200–450) ensures predictable biasing across production lots, while the SOT323 package supports compact PCB layouts with verified thermal performance up to TJ = 150 °C.
The device meets AEC-Q101 stress testing for automotive-grade reliability and exhibits low noise (F ≤ 4 dB) and high fT (250 MHz typ.), making it suitable for signal conditioning in sensor front-ends and clock buffer stages where gain stability and bandwidth matter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Supports operation in 3.3 V and 5 V rail systems with margin against transient overvoltage. |
| hFE (IC = 2 mA) | 200–450 - Enables stable DC bias design without gain binning compensation in production. |
| VCE(sat) | ≤ 200 mV at IC/IB = 10/0.5 mA - Minimizes power loss and self-heating in switching applications. |
| fT | 250 MHz typical - Sufficient for audio-band amplification and low-speed digital signal buffering. |
| Noise figure | 1.2–4 dB at 1 kHz - Meets low-noise requirements for microphone preamplifiers and sensor interfaces. |
| RthJS | ≤ 90 K/W - Enables reliable operation at Ptot = 250 mW with board-level heatsinking. |
Pinout & Package
BC847BWE6433HTMA1 is housed in a RoHS-compliant SOT323 plastic surface-mount package (3-pin, 1.3 mm × 2.1 mm × 0.95 mm), optimized for automated assembly and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-impedance return path; defines reference for base drive and collector load. |
| 2 (Base) | Control input | Receives current-limited drive (typically 1–10% of IC) to set operating point in active or saturation region. |
| 3 (Collector) | Current source terminal | Drives load (e.g., resistor, LED, next-stage input); voltage swing limited by VCEO = 45 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB, etc.). |
| Low VCE(sat) | ≤ 200 mV enables <10 mW dissipation at 10 mA collector current in saturated switch mode. |
| High hFE consistency | B-group (200–450) reduces need for external emitter degeneration or feedback trimming. |
| Low-noise operation | F = 1.2 dB typ. at 1 kHz supports precision analog signal paths without added filtering. |
Applications
| Audio Preamp Stage | Logic-Level Interface Driver |
|---|---|
Use Scenario: Amplifying weak signals from electret microphones or piezoelectric sensors in battery-powered voice recorders. IC Role / Device Role / Timing Role: Linear NPN amplifier configured in common-emitter topology with fixed bias or emitter degeneration. Use Value: Low noise (1.2 dB) and stable hFE ensure consistent gain across temperature and unit-to-unit variation. |
Use Scenario: Translating 1.8 V or 3.3 V GPIO outputs to drive 5 V TTL-compatible inputs in mixed-voltage MCU systems. IC Role / Device Role / Timing Role: Saturated switch providing level-shifting and current gain between incompatible logic families. Use Value: VCE(sat) ≤ 200 mV minimizes voltage drop and avoids false logic-low interpretation at receiver inputs. |
| Automotive Door Module Sensor Interface | Industrial PLC Input Conditioning |
Use Scenario: Buffering analog signals from seat occupancy or window position sensors in AEC-Q101-compliant vehicle modules. IC Role / Device Role / Timing Role: Signal conditioner and impedance translator placed between resistive sensor elements and ADC inputs. Use Value: AEC-Q101 qualification and 150 °C TJ rating ensure reliability under under-hood thermal cycling. |
Use Scenario: Isolating and amplifying 4–20 mA loop signals or dry-contact closures in factory-floor control cabinets. IC Role / Device Role / Timing Role: Discrete transistor used in optocoupler driver or current-sink interface stage. Use Value: High hFE (200–450) allows direct microcontroller GPIO drive without additional base-current limiting complexity. |
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 (Nexperia) | SOT323 package, same hFE B-group, but non-AEC-Q101 rated and higher RthJS (105 K/W). | Not qualified for automotive use; acceptable for commercial-grade consumer audio or industrial controls. | Select when AEC-Q101 compliance is unnecessary and cost sensitivity outweighs thermal margin. |
| MMBT3904LT1G (onsemi) | SOT23 package, hFE = 100–300 (standard grade), VCEO = 40 V, no AEC-Q101 certification. | Limited to non-automotive applications; lower VCEO restricts use in 48 V auxiliary circuits. | Choose for legacy SOT23 footprint compatibility where gain range and thermal specs are less critical. |
Compared with BC847BWE6433HTMA1, BC847BW,115 offers identical gain and package but lacks automotive qualification, while MMBT3904LT1G trades gain consistency and voltage margin for broader distributor availability and SOT23 fit.

FAQ
Is BC847BWE6433HTMA1 pin-compatible with BC847BW,115?
Yes - both use the SOT323 package with identical pinout (Emitter-Base-Collector on pins 1-2-3). Mechanical and soldering footprint compatibility is confirmed per JEDEC MO-203-DA standard, enabling direct replacement in existing layouts where AEC-Q101 compliance is not required.
What is the maximum continuous collector current at 125 °C ambient?
At TA = 125 °C, derated power dissipation limits IC to approximately 65 mA (based on Ptot = 250 mW and VCE(sat) ≤ 250 mV). This assumes adequate PCB copper area for heat spreading and no forced airflow; full 100 mA rating applies only at TA ≤ 71 °C.
Does BC847BWE6433HTMA1 support pulsed operation beyond its DC ratings?
Yes - pulse operation up to IC = 200 mA is permitted for tp ≤ 10 ms with duty cycle D ≤ 2%, per datasheet Figure 8. Thermal limits remain governed by junction temperature (TJ ≤ 150 °C), so pulse duration and repetition rate must be validated against actual board thermal resistance.
Can this transistor replace BC847B in existing SOT23 designs?
No - BC847BWE6433HTMA1 uses SOT323, which is smaller than SOT23 and has different pad dimensions and thermal characteristics. Direct substitution requires PCB layout revision. For SOT23 compatibility, consider BC847B,115 (Nexperia) or MMBT3904LT1G (onsemi), both with verified SOT23 footprints.
