Product details
Overview
BC847BS,115 from Nexperia is a dual NPN general-purpose transistor pair in SOT363-3 (TSSOP6) package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 200–450 at 2 mA/5 V; used for compact dual-switching and amplification in space-constrained signal routing and level-shifting circuits.
For engineers reviewing the BC847BS,115 datasheet, BC847BS,115 pinout, BC847BS,115 application, or BC847BS,115 equivalent, this device supports matched-pair operation with low mutual interference, low Cc (1.5 pF), and VCE(sat) ≤ 300 mV at 100 mA - critical for low-loss discrete logic and analog front-end design.
Technical Context
This dual NPN transistor integrates two electrically isolated transistors in one ultra-small SOT363-3 package, enabling independent biasing and switching without cross-coupling. Each transistor features identical absolute maximum ratings (VCEO = 45 V, IC = 100 mA) and tightly matched hFE across production lots.
The device operates with low thermal resistance (Rth(j-a) = 416 K/W per device on FR4), supports pulsed IC up to 200 mA, and delivers fT ≥ 100 MHz at 10 mA - suitable for audio-frequency amplification and digital switching below 10 MHz.
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 - sets maximum steady-state load current per transistor; supports small-signal relay drivers and LED sinks. |
| hFE | 200–450 at VCE = 5 V, IC = 2 mA - enables predictable base drive sizing for linear amplification and saturated switching. |
| VCE(sat) | ≤ 300 mV at IC = 100 mA, IB = 5 mA - ensures <100 mW power loss per transistor in saturation, reducing thermal load. |
| Cc | 1.5 pF at VCB = 10 V - minimizes high-frequency signal coupling and improves bandwidth in RF-adjacent analog stages. |
| Ptot | 400 mW per device on FR4 with 1 cm² collector pad - defines PCB copper area requirement for full-power operation at Tamb ≤ 25 °C. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height; designed for reflow soldering with standard stencil-defined paste volume.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects directly to ground or local return path. |
| 2 | Base of TR1 | Current-controlled input for TR1; requires series resistor to limit IB based on hFE and target IC. |
| 3 | Collector of TR2 | High-side output node for second transistor; routed to supply-rail loads or cascaded stages. |
| 4 | Emitter of TR2 | Independent emitter reference for TR2; allows separate biasing or floating configurations. |
| 5 | Base of TR2 | Isolated control input for TR2; no electrical coupling to TR1 base per datasheet specification. |
| 6 | Collector of TR1 | Primary output node for TR1; shares package thermal path with TR2 collector but remains electrically distinct. |
Key Features
| Feature | Design Value |
|---|---|
| No mutual interference | Electrically isolated die structure confirmed in pinning diagram and thermal derating curves - enables independent switching without crosstalk. |
| Closely matched hFE | Same process batch ensures <±10% hFE spread between TR1 and TR2 - simplifies differential pair biasing and current mirror design. |
| Low VCE(sat) | ≤300 mV at IC/IB = 20 - reduces conduction loss in battery-powered switch-mode circuits and extends runtime. |
| Reduced board space | Single SOT363-3 replaces two discrete SOT23 devices - saves >40% PCB area and eliminates two placement steps in SMT assembly. |
Applications
| LED Driver Pair | Dual-Level Shifter |
|---|---|
|
Use Scenario: Driving two independent indicator LEDs from microcontroller GPIOs with shared ground and separate anode control. IC Role / Device Role / Timing Role: Dual NPN switch providing low-side current sinking for each LED channel; no timing function required. Use Value: Eliminates need for two discrete transistors and associated passives, reducing BOM count by 3 components while maintaining independent brightness control. |
Use Scenario: Translating 1.8 V logic outputs to 3.3 V or 5 V levels for interfacing with legacy peripherals. IC Role / Device Role / Timing Role: Dual NPN configured as emitter followers or common-emitter inverters for bidirectional level translation. Use Value: Matched hFE ensures consistent threshold behavior across both channels, minimizing skew in parallel data lines. |
| Audio Preamp Stage | Discrete Logic Inverter Pair |
|
Use Scenario: Low-noise preamplification of microphone signals before ADC sampling in portable audio devices. IC Role / Device Role / Timing Role: Dual NPN configured in common-emitter topology with emitter degeneration for stable gain and linearity. Use Value: Low Cc (1.5 pF) preserves high-frequency response up to 100 kHz; low VBE variation (<100 mV) ensures balanced channel performance. |
Use Scenario: Implementing complementary logic functions (e.g., NOT + NAND) in repair scenarios where ASICs are unavailable. IC Role / Device Role / Timing Role: Two independent NPN switches forming active-low inverters with pull-up resistors on collector outputs. Use Value: Independent pinning allows non-overlapping drive signals; low VCE(sat) ensures clean logic '0' levels down to 300 mV for TTL-compatible inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC846BS,115 | Lower hFE range (110–220); same VCEO/IC ratings and SOT363-3 package. | Less suitable for low-base-drive designs requiring high current gain; acceptable where base current budget is ample. | Select when lower gain suffices and cost sensitivity outweighs hFE margin requirements. |
| MBT3904DW1T1G | Higher VCEO (60 V); hFE 100–300; same dual-NPN SOT363 footprint but different marking and thermal specs. | Better suited for higher-voltage industrial I/O; Rth(j-a) is 450 K/W vs. 416 K/W - slightly reduced thermal headroom. | Choose for 48 V system compatibility where BC847BS's 45 V rating is marginal. |
Compared with BC847BS,115, BC846BS,115 trades gain for cost in low-drive applications, while MBT3904DW1T1G extends voltage capability at the expense of tighter hFE tolerance and marginally higher thermal resistance - selection depends on whether gain, voltage headroom, or thermal performance dominates the design constraint.

FAQ
What is the maximum allowable junction temperature for BC847BS,115?
The absolute maximum junction temperature (Tj) is 150 °C per the IEC 60134 limiting values table. Operation above this threshold risks permanent degradation of hFE and increased leakage currents. Derating is required above 25 °C ambient, with Ptot decreasing linearly to zero at 150 °C junction temperature.
Can BC847BS,115 be used in linear amplifier configurations?
Yes - its specified hFE (200–450), low VCE(sat), and fT ≥ 100 MHz support Class-A and Class-AB audio preamplifier stages. Stable operation requires emitter degeneration resistors and proper thermal layout, as Ptot is limited to 400 mW with adequate copper area.
Is the BC847BS,115 pinout compatible with BC857BS,115?
No - BC857BS,115 is the PNP/PNP complement with reversed polarity and different pin mapping (e.g., pin 1 = C1, not E1). The BC847BS pinout is specific to NPN/NPN configuration and must not be substituted without verifying schematic connectivity and biasing polarity.
What does the '115' suffix indicate in BC847BS,115?
The '115' is Nexperia's tape-and-reel ordering code indicating 3,000 units per reel in standard SOT363-3 packaging. It does not denote parameter variation or revision - all electrical specifications match the base BC847BS type number defined in the 15 July 2026 product data sheet.
