Product details
Overview
BC847DS,115 from Nexperia is a dual NPN general-purpose transistor pair in SOT457 (SC-74) package, rated for 45 V VCEO, 100 mA IC, and DC current gain hFE of 200–450 per transistor; designed for compact dual-switching and amplification in automotive and industrial PCBs.
For engineers reviewing the BC847DS,115 datasheet, BC847DS,115 pinout, BC847DS,115 application, or BC847DS,115 equivalent, key selection criteria include matched hFE, low VCEsat (55–300 mV), AEC-Q101 qualification, and 6-pin dual-transistor layout with isolated operation.
Technical Context
This dual NPN device integrates two electrically isolated transistors on one die with tightly matched hFE (typ. 300 at IC = 2 mA, VCE = 5 V) and low inter-transistor coupling-no mutual interference confirmed per datasheet. Each transistor supports switching up to 100 mA continuous and 200 mA pulsed.
Thermal design is enabled by Rth(j-a) = 328 K/W per device on FR4 PCB, and junction temperature rating up to 150 °C. Low collector capacitance (1.9 pF) and transition frequency fT ≥ 100 MHz support medium-speed digital and analog signal handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit for switching applications. |
| IC | 100 mA - Continuous collector current per transistor; sets maximum load drive capability without derating. |
| hFE | 200–450 - DC current gain range at VCE = 5 V, IC = 2 mA; enables predictable base drive sizing for saturation. |
| VCEsat | 55–300 mV - Saturation voltage across collector-emitter at IC/IB = 20; determines conduction loss and heat generation in switch mode. |
| Cc | 1.9 pF - Collector capacitance at VCB = 10 V; impacts high-frequency response and switching speed in digital logic interfaces. |
| AEC-Q101 | Qualified - Meets automotive stress test requirements for discrete semiconductors; validated for under-hood and chassis-mounted use. |
Pinout & Package
SOT457 (SC-74) surface-mount plastic package with 6 leads, 3.0 mm × 1.7 mm footprint, and standard FR4-compatible reflow soldering profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Current sink node for first transistor; connects to ground or low-side load return path. |
| 2 | Base of TR1 | Control input for TR1; requires ~0.7 V forward bias and current-limited drive for saturation. |
| 3 | Collector of TR2 | Current source node for second transistor; ties to VCC or high-side load supply rail. |
| 4 | Emitter of TR2 | Current sink node for second transistor; independent of TR1 emitter for dual-channel isolation. |
| 5 | Base of TR2 | Independent control input for TR2; enables synchronous or separate switching of both transistors. |
| 6 | Collector of TR1 | Current source node for first transistor; routed separately from TR2 collector to prevent crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | 55 mV min at IC = 10 mA/IB = 0.5 mA - Reduces power dissipation in saturated switching, critical for thermally constrained layouts. |
| Closely matched hFE | Typical spread < ±10 % between TR1 and TR2 - Enables consistent gain and timing in differential or mirrored amplifier stages. |
| No mutual interference | Electrically isolated transistors on shared die - Eliminates crosstalk in dual-signal paths, e.g., push-pull drivers or dual-channel logic buffers. |
| Space-saving dual configuration | Single SOT457 replaces two discrete SOT23 devices - Cuts board area by ~40 % and reduces assembly cost via single placement step. |
Applications
| Automotive Door Module | Industrial PLC Input Stage |
|---|---|
|
Use Scenario: Driving LED status indicators and small solenoids in vehicle door control units. IC Role / Device Role / Timing Role: Dual NPN switch controlling parallel loads with independent enable signals.

IC Role / Device Role / Timing Role: Dual low-leakage switch managing two independent power/control paths. Use Value: ICBO ≤ 15 nA at 30 V ensures minimal standby current; 6-pin layout allows clean separation of high- and low-side control traces. |
Use Scenario: Amplifying low-level biopotential signals (ECG/EMG) before ADC sampling. IC Role / Device Role / Timing Role: First-stage common-emitter amplifier with noise figure NF = 1.9 dB at 10 Hz–15.7 kHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPDW1T3G | Same SOT457 package, but hFE bin 200–450 replaced with tighter 250–400; lower VCEsat (max 150 mV @ 100 mA). | Preferred where tighter hFE matching and lower conduction loss are required, e.g., precision current mirrors. | Select when consistency across production batches outweighs cost sensitivity; same footprint and drive compatibility. |
| MBT3904DW1T1G | Higher VCEO (60 V), higher fT (300 MHz), but no AEC-Q101 qualification; hFE range 100–300. | Suitable for non-automotive high-speed switching (e.g., SMPS gate drive), but not for qualified automotive modules. | Choose only for commercial-grade designs needing extended voltage headroom or RF performance; verify thermal derating on FR4. |
Compared with BC847DS,115, BC847BPDW1T3G offers tighter gain matching and lower saturation loss for precision analog use, while MBT3904DW1T1G trades automotive qualification for higher voltage and speed-making it unsuitable for AEC-compliant systems but viable in industrial switching.

FAQ
Is BC847DS,115 pin-compatible with BC847BPDW1T3G?
Yes-both use identical SOT457 (SC-74) package with matching pin 1–6 assignment (TR1 emitter, TR1 base, TR2 collector, TR2 emitter, TR2 base, TR1 collector). No PCB redesign is needed for substitution, though hFE binning and VCEsat differ slightly.
What is the maximum allowable ambient temperature for continuous operation?
BC847DS,115 supports continuous operation up to +150 °C ambient temperature when mounted on FR4 PCB with standard footprint, per datasheet Table 5. Derating begins above 25 °C ambient, with Ptot reduced linearly to zero at 150 °C.
Does BC847DS,115 support 5 V logic-level base drive?
Yes-VBE is 580–700 mV at IC = 2 mA, enabling direct drive from 5 V CMOS outputs with appropriate base resistor (e.g., 10 kΩ yields ~0.45 mA IB, sufficient for 100 mA IC at hFE ≥ 200).
Can BC847DS,115 be used in linear amplification mode?
Yes-its hFE stability (200–450), low noise figure (1.9 dB), and low capacitance (1.9 pF Cc) support Class-A small-signal amplification up to ~100 MHz, provided thermal limits (Ptot ≤ 380 mW per device) and VCE < 45 V are observed.
