Product details
Overview
BC847CWE6327BTSA1 from Infineon Technologies is an NPN silicon general-purpose bipolar junction transistor (BJT) designed for audio-frequency input stages and driver circuits. It features a minimum DC current gain (hFE) of 420 at IC = 10 µA, VCE = 5 V; VCEO = 45 V; VCE(sat) ≤ 250 mV at IC = 10 mA, IB = 0.5 mA; and fT = 250 MHz - enabling low-noise amplification in compact signal conditioning paths.
For engineers reviewing the BC847CWE6327BTSA1 datasheet, BC847CWE6327BTSA1 pinout, BC847CWE6327BTSA1 application, or BC847CWE6327BTSA1 equivalent, key selection criteria include its SOT-323 package footprint, AEC-Q101 qualification for automotive use, low VCE(sat) for efficient switching, and hFE group C consistency across production lots.
Technical Context
This transistor operates as a linear amplifier or saturated switch in low-power analog and digital interface stages. Its hFE range (420–800 at IC = 2 mA) supports stable biasing in emitter-follower and common-emitter configurations, while fT = 250 MHz ensures adequate bandwidth for AF and low-MHz signal handling.
The device meets AEC-Q101 stress testing requirements for automotive electronics and uses a Pb-free, RoHS-compliant SOT-323 package with thermal resistance RthJS ≤ 90 K/W, supporting reliable operation up to Tj = 150 °C under continuous 250 mW dissipation at TS ≤ 128 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - supports rail-to-rail operation in 3.3 V and 5 V logic-level driver circuits without breakdown risk |
| hFE (min) | 420 at IC = 10 µA - enables high-gain preamplifier stages with minimal base drive current |
| VCE(sat) | ≤ 250 mV at IC = 10 mA - reduces conduction loss in low-side switching applications |
| fT | 250 MHz - sufficient for audio-band amplification and fast digital edge shaping up to ~50 MHz |
| Ccb | 0.95 pF - limits Miller effect in high-frequency gain stages, improving stability |
| Ptot | 250 mW at TS ≤ 128 °C - defines maximum continuous power in thermally constrained PCB layouts |
| Noise figure | 1.2 dB typ. at IC = 200 µA - suitable for low-noise microphone preamp inputs |
Pinout & Package
BC847CWE6327BTSA1 is housed in a RoHS-compliant SOT-323 (SC-70) plastic surface-mount package measuring 2.1 mm × 2.0 mm × 0.9 mm, optimized for high-density PCB assembly and automated reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Provides low-impedance return path; connected to ground or negative rail in common-emitter configuration |
| 2 (Base) | Control input | Accepts small-signal current to modulate collector current; requires series resistor for current limiting |
| 3 (Collector) | Current source terminal | Delivers amplified output current; connects to load or next stage's input impedance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards |
| Low VCE(sat) | 250 mV max at IC/IB = 10/0.5 - minimizes voltage drop and self-heating in switching mode |
| High hFE group C | 420–800 at IC = 2 mA - reduces base drive requirements and improves current sourcing accuracy |
| Low noise performance | 1.2 dB noise figure at 1 kHz - preserves SNR in sensitive analog front-end designs |
| SOT-323 footprint | Compatible with standard 0805 land pattern - simplifies layout reuse and reduces board space vs. SOT-23 |
Applications
| Automotive Door Module Driver | USB-C Power Path Control |
|---|---|
Use Scenario: Driving LED status indicators and small solenoids in vehicle door control units exposed to -40 °C to +125 °C ambient. IC Role / Device Role / Timing Role: NPN switch controlling 20 mA LED loads and 50 mA relay coils via microcontroller GPIO. Use Value: AEC-Q101 qualification ensures lifetime reliability; low VCE(sat) prevents thermal runaway during sustained activation. | Use Scenario: Enabling/disabling VBUS power delivery paths in portable USB-C accessories with tight thermal budgets. IC Role / Device Role / Timing Role: Low-side switch in discrete OR-ing circuit between two power sources. Use Value: High hFE allows direct GPIO drive without buffer; SOT-323 footprint fits space-constrained USB-C port modules. |
| Industrial Sensor Signal Conditioning | Audio Line Driver Amplifier |
Use Scenario: Amplifying millivolt-level outputs from RTD or bridge-based pressure sensors in factory automation nodes. IC Role / Device Role / Timing Role: Common-emitter preamplifier stage with fixed bias network before ADC input. Use Value: 1.2 dB noise figure preserves sensor resolution; 420+ hFE ensures stable gain across temperature. | Use Scenario: Buffering line-level audio signals (≤ 2 Vpp) from DACs to headphone jacks in smart speakers. IC Role / Device Role / Timing Role: Emitter-follower output stage delivering low-impedance drive into 32 Ω loads. Use Value: fT = 250 MHz provides ample bandwidth for full 20 Hz–20 kHz response; low Ccb avoids high-frequency roll-off. |
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 |
|---|---|---|---|
| BC847CB,632 (Nexperia) | Same SOT-323 package, identical hFE group C (420–800), but rated for VCEO = 45 V and Ptot = 300 mW at TS ≤ 125 °C | Higher power rating supports marginally higher continuous current in non-automotive industrial use | Select when thermal headroom >50 mW is required and AEC-Q101 is not mandatory |
| MMBT3904LT1G (ON Semiconductor) | SOT-23 package, hFE = 100–300 (lower gain), VCEO = 40 V, fT = 300 MHz, no AEC-Q101 qualification | Larger footprint and lower gain necessitate redesign of bias network and layout | Choose only if higher fT is critical and automotive compliance is excluded |
Compared with BC847CB,632 and MMBT3904LT1G, BC847CWE6327BTSA1 uniquely combines AEC-Q101 qualification, SOT-323 compactness, and high hFE group C - making it optimal for space-constrained automotive and industrial signal chains where gain stability and reliability are prioritized over raw speed or absolute power rating.

FAQ
Is BC847CWE6327BTSA1 pin-compatible with BC847B variants?
No - BC847CWE6327BTSA1 uses the SOT-323 package with pin 1 = Emitter, pin 2 = Base, pin 3 = Collector. BC847B variants in SOT-23 share the same pinout order but differ in thermal performance and package dimensions. Mechanical interference may occur if substituted without land pattern verification.
What is the maximum operating junction temperature?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in the Infineon BC846–BC850 datasheet. Derating begins at TS > 128 °C, where Ptot decreases linearly to zero at 150 °C. Thermal design must ensure RthJA remains within safe limits for the target PCB stack-up.
Does this transistor support pulsed operation beyond its DC ratings?
Yes - pulse operation is permitted with duty cycle D ≤ 2% and pulse width tp ≤ 300 µs, allowing peak collector current up to 200 mA. The permissible pulse load curve (Figure EHP00362) shows Ptot(max)/Ptot(DC) = 2.5 at tp = 10 ms, provided average power stays within 250 mW limits.
Can BC847CWE6327BTSA1 replace BC847CW in existing designs?
Yes - BC847CWE6327BTSA1 and BC847CW both belong to the BC847C hFE group and share identical electrical specifications and SOT-323 packaging. The "E6327" suffix denotes Infineon's tape-and-reel packaging standard, and "BTSA1" indicates RoHS-compliant reel format; no functional or parametric differences exist.
