Product details
Overview
BC847BWE6327BTSA1 from Infineon Technologies is an NPN silicon general-purpose bipolar junction transistor (BJT) designed for audio-frequency input stages and driver applications. It features a DC current gain (hFE) of 200–450 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 - used in compact signal amplification and switching circuits.
For engineers reviewing the BC847BWE6327BTSA1 datasheet, BC847BWE6327BTSA1 pinout, BC847BWE6327BTSA1 application, or BC847BWE6327BTSA1 equivalent, key selection criteria include its SOT-323 (SC-70) package, AEC-Q101 qualification for automotive use, RoHS-compliant Pb-free construction, and verified hFE group B performance across temperature.
Technical Context
This transistor operates as a linear amplifier or saturated switch in low-power analog and digital interface circuits. Its hFE grouping (B: 200–450), low VCE(sat), and fT = 250 MHz support stable small-signal gain and fast switching up to ~10 MHz.
Designed for thermal reliability in space-constrained PCBs, it delivers Ptot = 250 mW at TS ≤ 128 °C and RthJS ≤ 90 K/W in its SOT-323 package - enabling use in thermally dense automotive cabin electronics and industrial sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - supports rail-to-rail operation in 3.3 V/5 V/12 V logic-level interfaces without breakdown risk |
| hFE (IC = 2 mA) | 200–450 - ensures predictable biasing and gain stability in emitter-follower and common-emitter amplifier stages |
| VCE(sat) | ≤250 mV @ IC/IB = 10 mA/0.5 mA - minimizes conduction loss in low-side switching and LED driver saturation |
| fT | 250 MHz - enables reliable operation in audio preamps and clock buffer stages up to 10 MHz |
| Noise figure | 1.2–4 dB @ 1 kHz - meets SNR requirements for microphone preamplifiers and sensor signal conditioning |
| Ptot | 250 mW @ TS ≤ 128 °C - allows continuous operation in sealed enclosures with limited airflow |
| RthJS | ≤90 K/W - supports thermal design margin in automotive ambient temperatures up to 105 °C junction |
Pinout & Package
BC847BWE6327BTSA1 is housed in a Pb-free, RoHS-compliant SOT-323 (SC-70) surface-mount plastic package with gull-wing leads and a thermal pad footprint optimized for PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-impedance return path; defines reference for VBE bias and sets emitter degeneration resistor placement |
| 2 (Base) | Control input | Receives drive current to modulate collector current; requires series resistor to limit IB and prevent thermal runaway |
| 3 (Collector) | Current source terminal | Delivers amplified output current; routed to load or next stage; layout must minimize parasitic inductance for high-frequency stability |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood and cabin applications per stress test requirements including HTOL, TC, and ESD |
| Low VCE(sat) | Reduces power loss and self-heating in battery-powered drivers and always-on sensor nodes |
| Group B hFE binning | Enables consistent circuit behavior across production lots without post-assembly gain trimming |
| Low-noise operation | Supports high-fidelity audio signal paths and precision instrumentation amplifier front-ends |
| SOT-323 package | Enables <1.6 mm² board area usage while maintaining manufacturability on standard SMT lines |

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) | Same SOT-323 package, identical hFE group B (200–450), but not AEC-Q101 qualified | Limited to commercial-grade consumer electronics; unsuitable for automotive OEM designs | Select when cost sensitivity outweighs automotive qualification requirement |
| MMBT3904LT1G (ON Semiconductor) | Higher VCEO = 40 V (vs. 45 V), lower hFE min = 100, same SOT-23 package (not SOT-323) | Requires PCB redesign due to different footprint; less gain consistency at low IC | Choose only if existing SOT-23 layout reuse is mandatory and gain tolerance can be relaxed |
Compared with BC847BW,115 and MMBT3904LT1G, BC847BWE6327BTSA1 uniquely combines AEC-Q101 compliance, SOT-323 miniaturization, and tight hFE binning - making it optimal for space-constrained automotive and industrial signal chains where reliability and repeatability are non-negotiable.

FAQ
Is BC847BWE6327BTSA1 pin-compatible with BC847B,115?
Yes - both use the SOT-323 (SC-70) package with identical pin 1 (Emitter), pin 2 (Base), pin 3 (Collector) assignment. Mechanical and electrical pinout matches exactly, enabling direct replacement without layout change.
What is the maximum junction temperature during continuous operation?
The absolute maximum junction temperature is 150 °C. Under typical conditions with TS ≤ 128 °C and Ptot = 250 mW, steady-state Tj remains ≤ 135 °C - verified per Infineon's thermal resistance data (RthJS ≤ 90 K/W).
Does this transistor support pulsed operation beyond its DC ratings?
Yes - pulse operation up to IC = 200 mA is allowed for tp ≤ 10 ms (duty cycle ≤ 2%), as specified in the Absolute Maximum Ratings table. Derating curves confirm safe operation within thermal limits under short-duration loads.
Can BC847BWE6327BTSA1 replace BC847C in a design?
No - BC847C has hFE = 420–800 (group C), while BC847BWE6327BTSA1 is group B (200–450). Gain mismatch may cause bias point shift or instability in feedback-critical circuits like oscillators or precision amplifiers.
