Product details
Overview
BC847CE6433HTMA1 from Nexperia is an NPN silicon general-purpose bipolar junction transistor (BJT) designed for audio-frequency input stages and driver circuits. It delivers high DC current gain (hFE = 420–520 at IC = 2 mA), low VCE(sat) (≤250 mV at IC = 10 mA/IB = 0.5 mA), and low noise (F = 1.2–4 dB at 1 kHz), making it suitable for low-noise preamplifier and signal-switching applications in automotive and industrial electronics.
For engineers reviewing the BC847CE6433HTMA1 datasheet, BC847CE6433HTMA1 pinout, BC847CE6433HTMA1 application, or BC847CE6433HTMA1 equivalent, key selection criteria include verified hFE group C performance, SOT23 package thermal resistance (RthJS ≤ 240 K/W), AEC-Q101 qualification, and complementary PNP pairing with BC857C/BC858C.
Technical Context
This transistor operates as a linear amplifying or saturated switching device in low-voltage analog and digital interface circuits. Its hFE group C rating ensures consistent current amplification across production lots, while its fT = 250 MHz supports stable operation up to mid-VHF frequencies under small-signal conditions.
The device features low base-emitter on-voltage (VBE(ON) = 660–770 mV at IC = 10 mA), tight VCE(sat) control (≤600 mV at IC = 100 mA/IB = 5 mA), and low Ccb (0.95 pF) - enabling fast switching and minimal Miller effect in gain-stage design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Supports rail voltages up to 36 V in automotive 12 V systems with margin. |
| hFE (IC = 2 mA) | 420–520 - Enables high-gain, low-base-drive amplifier stages without cascading. |
| VCE(sat) | ≤250 mV @ IC/IB = 10/0.5 mA - Reduces conduction loss in active-load and switch-mode driver topologies. |
| fT | 250 MHz - Ensures usable bandwidth for audio harmonics and clock buffering up to ~30 MHz. |
| Ccb | 0.95 pF - Minimizes feedback capacitance in common-emitter configurations. |
| Noise figure | 1.2–4 dB @ 1 kHz - Meets low-noise requirements for microphone preamps and sensor front-ends. |
| RthJS | ≤240 K/W - Allows 330 mW dissipation at TS ≤ 71 °C in standard PCB layouts. |
Pinout & Package
BC847CE6433HTMA1 is housed in a RoHS-compliant SOT23 plastic surface-mount package (JEDEC TO-236AB), measuring 2.9 × 1.3 × 1.0 mm, with gull-wing leads optimized for automated reflow assembly and thermal reliability in high-volume production.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Current-controlled input node | Accepts low-current drive (≤5 mA) to bias transistor into active or saturation region. |
| 2 (Emitter) | Reference terminal / current sink | Connected to ground or low-impedance return path; defines VBE reference for bias network. |
| 3 (Collector) | Output current source/sink | Delivers amplified load current; requires appropriate pull-up/pull-down and voltage margin per VCEO. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB). |
| Low-noise operation | F = 1.2 dB typ. at 1 kHz enables use in precision analog front-ends without added filtering. |
| High hFE group C | Guaranteed hFE ≥ 420 at 2 mA ensures predictable gain without binning or trimming. |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C). |
| Complementary PNP pairing | Matches BC857C/BC858C for push-pull output stages and differential amplifiers. |
Applications

Use Value: SOT23 footprint and RthJS ≤ 240 K/W support reliable 100 mA switching without heatsinking. |
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 |
|---|---|---|---|
| BC847CW | Same hFE group C, identical SOT323 package, lower Ptot (250 mW vs. 330 mW). | Preferred where board space allows smaller footprint but thermal budget is tighter. | Select when footprint reduction outweighs need for maximum power handling. |
| MMBT3904LT1G | hFE = 100–300 (lower gain spread), higher VCEO = 40 V, same SOT23 package. | Used in cost-sensitive consumer designs where tighter hFE tolerance is not required. | Choose for non-automotive applications where AEC-Q101 and guaranteed hFE ≥ 420 are not mandatory. |
Compared with BC847CW and MMBT3904LT1G, BC847CE6433HTMA1 offers superior hFE consistency, AEC-Q101 validation, and higher power dissipation - making it optimal for automotive signal conditioning and industrial analog interfaces demanding long-term reliability.

FAQ
What is the maximum continuous collector current for BC847CE6433HTMA1?
The absolute maximum continuous collector current (IC) is 100 mA at TA = 25 °C. Derating applies above 71 °C case temperature, where total power dissipation drops from 330 mW to zero at 150 °C junction temperature. Peak pulsed current reaches 200 mA for tp ≤ 10 ms with duty cycle ≤ 2%.
Is BC847CE6433HTMA1 suitable for automotive applications?
Yes - it is fully qualified to AEC-Q101 standards, including HTOL, temperature cycling, and HTRB testing. Its guaranteed hFE group C, low VCE(sat), and operation from −55 °C to +150 °C junction temperature make it approved for under-hood and body electronics in passenger vehicles and commercial fleets.
How does BC847CE6433HTMA1 differ from BC847B variants?
BC847CE6433HTMA1 is hFE group C (420–520), whereas BC847B is group B (200–450). Group C provides higher and tighter gain distribution, critical for gain-stable amplifier designs. Both share identical SOT23 package, VCEO = 45 V, and AEC-Q101 qualification.
Can BC847CE6433HTMA1 replace BC847C in existing designs?
Yes - BC847CE6433HTMA1 is a direct functional and mechanical replacement for BC847C, sharing identical pinout, electrical specifications, and SOT23 packaging.
