Product details
Overview
BC847CM,315 from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in ultra-small SOT883 (SC-101) package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 420–800 at VCE = 5 V / IC = 2 mA. It serves as a low-power switching and amplification device in space-constrained automotive and industrial signal paths.
For engineers reviewing the BC847CM,315 datasheet, BC847CM,315 pinout, BC847CM,315 application, or BC847CM,315 equivalent, key selection criteria include its high-gain binning, thermal resistance (Rth(j-a) = 500 K/W), AEC-Q101 qualification, and SOT883 footprint compatibility with high-density PCB layouts.
Technical Context
This transistor operates as a discrete NPN bipolar junction device with base-controlled current amplification. Its design supports linear amplification (VBE = 580–700 mV at VCE = 5 V / IC = 2 mA) and saturated switching (VCE(sat) ≤ 400 mV at IC = 100 mA / IB = 5 mA).
It features three gain bins (AM/BM/CM) within the same SOT883 package, enabling consistent performance across production lots. The device meets IEC 60134 absolute maximum ratings and exhibits stable hFE over −55 °C to +150 °C ambient range, validated per AEC-Q101 stress test requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, small relays, and logic-level interface loads. |
| hFE | 420–800 @ VCE = 5 V, IC = 2 mA - High DC current gain bin ensures low base drive requirements in amplifier and switch applications. |
| Ptot | 250 mW @ Tamb ≤ 25 °C - Power dissipation limit on standard FR4 PCB; defines thermal derating envelope for sustained operation. |
| Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance; informs PCB copper area and layout cooling needs for thermal management. |
| VBE(sat) | 900 mV @ IC = 100 mA, IB = 5 mA - Base-emitter saturation voltage determines minimum MCU GPIO drive capability required for full turn-on. |
Pinout & Package
SOT883 (SC-101) is an ultra-small leadless surface-mount plastic package measuring 1.0 × 0.6 × 0.5 mm, optimized for high-density PCB assembly and reflow soldering. It features three solder lands with transparent top-view marking and no exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires ~5 mA base current to saturate at 100 mA collector load, enabling direct microcontroller GPIO drive. |
| 2 | Emitter (E) | Current return path; internally connected to substrate; must be tied to system ground or low-side reference for proper biasing. |
| 3 | Collector (C) | Output current path; connects to load (e.g., LED anode or relay coil); reverse-biased during off-state up to 45 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - supports under-hood and infotainment module deployment. |
| High hFE bin (CM) | Guaranteed 420–800 gain at 2 mA collector current - reduces base drive power and improves noise immunity in analog front-end stages. |
| Ultra-small SOT883 footprint | 1.0 × 0.6 mm body size - saves >60% board area vs. SOT23, enabling miniaturized sensor nodes and wearable electronics. |
| Low VCE(sat) | ≤400 mV at 100 mA - minimizes conduction loss in switching applications, improving efficiency in battery-powered systems. |

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 | SOT323 package (2.1 × 1.25 mm), lower hFE (420–800 same bin but higher VCE(sat) typical 500 mV) | Larger footprint; less suitable for ultra-dense layouts but easier to hand-solder and rework | Select when manual assembly or thermal margin >500 mW is required |
| MMBT3904LT1G | SOT23 package (3.0 × 1.4 mm), hFE 100–300 (lower gain bin), not AEC-Q101 qualified | Higher power dissipation (310 mW), wider availability, non-automotive grade | Select for cost-sensitive industrial controls where automotive qualification is unnecessary |
Compared with BC847CM,315, BC847CW,115 trades miniaturization for assembly flexibility, while MMBT3904LT1G offers broader distribution at the expense of gain consistency and automotive compliance - making BC847CM,315 optimal for space- and reliability-critical designs.

FAQ
What is the maximum junction temperature for BC847CM,315?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent parametric shift or failure. Derating is required above 25 °C ambient, using Rth(j-a) = 500 K/W to calculate allowable power at elevated temperatures.
Is BC847CM,315 suitable for linear amplifier applications?
Yes - its specified VBE (580–700 mV at VCE = 5 V / IC = 2 mA) and stable hFE over temperature support Class-A and emitter-follower configurations. However, thermal limitations (250 mW Ptot) restrict continuous output power to low-level signal stages only.
How does the SOT883 package affect soldering process compatibility?
The SOT883 footprint uses three solder lands with no exposed thermal pad and requires precise stencil aperture design (0.3 mm land width, 0.25 mm paste thickness). Reflow profiles must follow J-STD-020, with peak temperature ≤260 °C and time above liquidus 60–90 seconds to ensure void-free joints and mechanical reliability.
Does BC847CM,315 have built-in ESD protection?
No - it lacks integrated ESD diodes. Per Nexperia's documentation, the device has HBM ESD rating of 8 kV (Class 3A), achieved via process-level robustness rather than on-chip clamps. External TVS or series resistors are recommended for I/O lines exposed to handling or connector interfaces.
