Product details
Overview
BC847CW-Q from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in SOT323 (SC-70) package, designed for automotive-grade switching and amplification. It delivers VCEO = 45 V, IC = 100 mA, hFE = 420–800 at VCE = 5 V / IC = 2 mA, and operates across −65 °C to +150 °C ambient.
For engineers reviewing the BC847CW-Q datasheet, BC847CW-Q pinout, BC847CW-Q application, or BC847CW-Q equivalent, this device serves as a high-reliability, small-footprint discrete switch or linear amplifier in space-constrained automotive control modules, sensor interface stages, and LED driver bias circuits.
Technical Context
The BC847CW-Q implements a planar epitaxial NPN silicon structure optimized for stable DC current gain across temperature and current ranges. Its hFE bin (420–800) enables precise biasing in low-power analog amplifiers and predictable saturation behavior in digital switching applications.
Qualified per AEC-Q101, it supports automotive use with guaranteed operation up to Tj = 150 °C, Rth(j-a) = 625 K/W on FR4 PCB, and robust ESD tolerance (HBM > 2 kV). The SOT323 package ensures compatibility with standard reflow profiles and high-density layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IC | 100 mA continuous - Sustains typical load currents in microcontroller I/O drivers and sensor signal conditioning stages. |
| hFE | 420–800 @ VCE = 5 V, IC = 2 mA - Enables low-base-drive designs for efficient switching in battery-powered modules. |
| VCE(sat) | 200–400 mV @ IC = 100 mA, IB = 5 mA - Minimizes conduction loss in active-low logic-level switches and relay drivers. |
| Ptot | 200 mW @ Tamb ≤ 25 °C - Defines thermal derating envelope for surface-mount placement on standard FR4 PCBs. |
| Tj(max) | 150 °C - Junction temperature limit enabling reliable operation in under-hood automotive environments. |
| fT | 100 MHz @ VCE = 5 V, IC = 10 mA - Supports audio-frequency amplification and fast digital switching up to ~10 MHz. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 3-lead, ultra-small footprint (2.2 mm × 1.35 mm × 0.95 mm), optimized for automated assembly and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires ~0.66 V forward bias to initiate conduction; base current determines collector current scaling via hFE. |
| 2 | Emitter (E) | Current return path; tied to ground or low-side reference in common-emitter configurations; defines emitter-follower output impedance. |
| 3 | Collector (C) | Output terminal; sinks load current in switching mode; connects to positive rail in high-side emitter-follower topologies. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| Three hFE gain bins | BC847CW-Q's 420–800 hFE range allows consistent bias design without manual sorting in production. |
| SOT323 (SC-70) package | 0.65 mm pitch, 2.2 mm × 1.35 mm footprint - fits tight spaces where SO-23 or SOT23 are too large. |
| Low VCE(sat) | ≤400 mV at full 100 mA load - reduces power dissipation and heat rise in always-on control circuits. |
| Wide operating temperature | −65 °C to +150 °C ambient - supports deployment in extreme under-hood or industrial ambient conditions. |
Applications

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 |
|---|---|---|---|
| BC847C-Q (Nexperia) | Same electrical specs but in SOT23 package; larger footprint (2.9 mm × 1.3 mm) and higher Rth(j-a) (300 K/W). | Preferred where board space permits and thermal performance demands lower junction rise. | Select when legacy SOT23 layout compatibility or higher power handling (>200 mW) is required. |
| MMBT3904LT1G (onsemi) | hFE = 100–300 (lower gain bin); VCEO = 40 V; not AEC-Q101 qualified. | Suitable for commercial-grade consumer electronics but not automotive safety-critical functions. | Choose only for cost-sensitive non-automotive applications where gain consistency and qualification are not mandatory. |
Compared with BC847C-Q and MMBT3904LT1G, the BC847CW-Q uniquely combines AEC-Q101 compliance, SC-70 miniaturization, and high hFE for automotive signal switching where space, reliability, and gain stability are jointly constrained.

FAQ
Is BC847CW-Q pin-compatible with BC847C-Q?
No. BC847CW-Q uses SOT323 (SC-70) with 0.65 mm lead pitch and 2.2 mm × 1.35 mm body, while BC847C-Q uses SOT23 with 1.9 mm × 1.3 mm body and 0.95 mm pitch. Footprints and solder stencil designs are not interchangeable.
What is the maximum pulsed collector current rating?
The peak collector current is 200 mA for single pulses ≤1 ms (duty cycle ≤0.02), as specified in Table 6. This enables short-duration surge handling in motor commutation or fault detection circuits without thermal runaway.
Does BC847CW-Q support wave soldering?
Yes. Nexperia provides dedicated wave soldering footprint data (Fig. 16) with recommended solder land dimensions and transport direction guidance. Thermal profile must respect peak temperature ≤260 °C and dwell time ≤5 s per JEDEC J-STD-020.
How does hFE vary with temperature?
hFE increases with junction temperature - Fig. 10 shows typical gain rising from ~420 at −55 °C to ~1000 at 150 °C (at IC = 2 mA). Designers must verify bias stability across the full operating range using worst-case hFE extremes.
