Product details
Overview
BC847CWH6327XTSA1 from Infineon Technologies is an NPN silicon bipolar junction transistor designed for audio-frequency input stages and driver circuits. It features a DC current gain (hFE) of 420–800 at IC = 2 mA, VCE = 5 V; VCEO = 45 V; VCE(sat) ≤ 250 mV at IC = 10 mA, IB = 0.5 mA; and low noise (F = 1.2–4 dB) in the 1 kHz band - enabling high-fidelity signal amplification in compact consumer audio preamps.
For engineers reviewing the BC847CWH6327XTSA1 datasheet, BC847CWH6327XTSA1 pinout, BC847CWH6327XTSA1 application, or BC847CWH6327XTSA1 equivalent, key selection criteria include its SOT323 package footprint, AEC-Q101 qualification for automotive-grade reliability, RoHS-compliant lead-free construction, and verified hFE group C performance across temperature.
Technical Context
This transistor operates as a general-purpose NPN amplifier with fixed-emitter bias topology, optimized for linear operation in low-noise analog front-ends. Its fT = 250 MHz supports stable gain up to mid-VHF, while Ccb = 0.95 pF and Ceb = 9 pF minimize Miller effect in common-emitter configurations.
The device uses epitaxial planar technology with gold-doped base region to achieve tight hFE distribution (group C: 420–800), low VCE(sat), and robust thermal stability (Tj = 150 °C). Junction-to-soldering-point thermal resistance RthJS = 105 K/W confirms suitability for thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - supports rail-to-rail operation in 3.3 V/5 V/12 V audio and logic interface stages without breakdown risk |
| hFE (IC = 2 mA) | 420–800 - enables precise biasing and predictable gain in discrete amplifier designs without trimming |
| VCE(sat) | ≤250 mV at IC/IB = 10 mA/0.5 mA - reduces conduction loss and self-heating in switching and Class-A driver roles |
| fT | 250 MHz - ensures stable small-signal amplification up to 20 MHz with ≥10 dB gain margin |
| Noise figure | 1.2–4 dB at 1 kHz - meets SNR requirements for microphone preamplifiers and sensor signal conditioning |
| RthJS | 105 K/W - allows continuous 250 mW dissipation at board-level soldering point ≤124 °C |
Pinout & Package
SOT323 (SC-70) 3-pin surface-mount package with standard JEDEC outline: 1.3 mm × 2.1 mm × 0.95 mm height, gull-wing leads, RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-impedance return path; defines reference for VBE and hFE control |
| 2 (Base) | Control input node | Receives bias current to set operating point; requires series resistor for stable DC feedback |
| 3 (Collector) | Current source output | Drives load or next stage; voltage swing limited by VCEO and power dissipation constraints |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB), enabling use in infotainment and body control modules |
| Low VCE(sat) | 250 mV max at IC/IB = 10 mA/0.5 mA - minimizes voltage drop and power loss in active-load and switch-mode driver applications |
| Group C hFE | 420–800 range at IC = 2 mA - eliminates need for binning or external gain compensation in production assemblies |
| Low-noise design | F = 1.2 dB typ. at 1 kHz - preserves signal integrity in microphone, piezo, and precision sensor front-ends |
Applications
| Audio Preamp Stage | Automotive Door Module Driver |
|---|---|
|

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,115 (Nexperia) | Same SOT323 package, identical hFE group C (420–800), but rated VCEO = 45 V and not AEC-Q101 qualified | Lacks automotive stress validation; suitable only for commercial-grade consumer electronics | Select when cost sensitivity outweighs automotive qualification requirement |
| MMBT3904LT1G (onsemi) | Higher VCEO = 60 V, lower hFE range (100–300), same SOT23-3 footprint (not pin-compatible with SOT323) | Requires PCB redesign due to different package; better for higher-voltage industrial logic interfaces | Choose only if board layout allows SOT23 and system voltage exceeds 45 V |
Compared with BC847CWH6327XTSA1, the BC847CW,115 offers identical electrical specs but no automotive qualification, while MMBT3904LT1G trades hFE consistency and package compatibility for higher breakdown voltage - making the Infineon part optimal for AEC-Q101–compliant, low-noise, high-gain audio and sensor front-ends.

FAQ
Is BC847CWH6327XTSA1 pin-compatible with BC847BW?
No. BC847CWH6327XTSA1 uses the SOT323 (SC-70) package with 1.3 mm × 2.1 mm footprint, while BC847BW uses SOT23 with 2.9 mm × 1.3 mm dimensions and different lead pitch. Physical mounting and PCB land patterns are incompatible, and no adapter is standardized.
What is the maximum continuous collector current at 85 °C ambient?
At TA = 85 °C, derating applies: Ptot = 250 mW at TS = 124 °C implies usable IC ≤ 85 mA for VCE = 5 V (assuming 0.425 W thermal budget and typical VCE(sat)). Full 100 mA rating is valid only at TA ≤ 55 °C with adequate copper pour.
Does this transistor support pulsed operation above 200 mA?
Yes - peak collector current ICM = 200 mA is specified for pulse width tp ≤ 10 ms with duty cycle D ≤ 2%. At tp = 1 ms, permissible IC rises to ~280 mA per thermal transient curves (EHP00362), provided average power remains within 250 mW limits.
Can BC847CWH6327XTSA1 replace BC847BL3 in existing designs?
No - BC847BL3 uses TSLP-3-1 package (0.8 mm × 0.8 mm, 0.35 mm pitch) with different thermal resistance (RthJS = 60 K/W) and solder profile. Substitution would require requalification due to mechanical fit, thermal performance, and reflow compatibility differences.
