Product details
Overview
BC846S/DG/B2,115 from Nexperia is a dual NPN general-purpose transistor in a single SOT363-3 (SC-88/TSSOP6) package, with independent emitter-base-collector terminals for each transistor, VCEO = 65 V, IC = 100 mA per transistor, and hFE ≥ 110 at 2 mA/5 V - used in compact signal switching and low-power amplification stages on space-constrained PCBs.
For engineers reviewing the BC846S/DG/B2,115 datasheet, BC846S/DG/B2,115 pinout, BC846S/DG/B2,115 application, or BC846S/DG/B2,115 equivalent, key selection criteria include per-transistor breakdown voltage, thermal resistance (Rth(j-a) = 568 K/W), dual-device isolation, and SMT footprint compatibility with FR4 PCBs using standard reflow profiles.
Technical Context
This double NPN transistor integrates two electrically isolated silicon planar epitaxial devices in one monolithic SOT363-3 package, enabling independent biasing and operation without crosstalk. Each transistor supports DC current gain (hFE) ≥ 110 at 2 mA and exhibits VCE(sat) ≤ 300 mV at IC = 100 mA / IB = 5 mA.
Thermal performance is defined for FR4 PCB mounting: per-transistor Rth(j-a) = 568 K/W and per-device Rth(j-a) = 416 K/W, with Ptot = 220 mW per transistor and 300 mW per device at Tamb ≤ 25 °C - critical for thermal-aware layout of dual-channel analog or digital logic interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - maximum collector-emitter voltage before breakdown under open-base condition; defines safe operating voltage headroom in switching applications. |
| IC | 100 mA - continuous collector current per transistor; sets upper limit for load-driving capability in small-signal stages. |
| hFE | ≥110 at VCE = 5 V, IC = 2 mA - minimum DC current gain ensures reliable base-driven switching with low drive current. |
| VCE(sat) | ≤300 mV at IC = 100 mA, IB = 5 mA - low saturation voltage minimizes power loss and heating during ON-state operation. |
| Rth(j-a) | 568 K/W per transistor - thermal resistance determines junction temperature rise above ambient; requires careful copper area planning on PCB. |
| fT | 100 MHz - transition frequency confirms suitability for audio-frequency amplification and low-speed digital switching up to ~10 MHz. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 6-pin, 2.2 mm × 1.35 mm body, 0.65 mm pitch, 0.45 mm max height, designed for automated placement and reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E1 | Emitter of Transistor 1 - common reference node for TR1; connects to ground or low-side return path. |
| 2 | B1 | Base of Transistor 1 - control input for TR1; requires current-limiting resistor for safe biasing. |
| 3 | C2 | Collector of Transistor 2 - high-side output node for TR2; connects to load or pull-up network. |
| 4 | E2 | Emitter of Transistor 2 - independent reference for TR2; enables separate grounding or level-shifting schemes. |
| 5 | B2 | Base of Transistor 2 - isolated control input for TR2; allows asynchronous or differential drive. |
| 6 | C1 | Collector of Transistor 1 - primary output node for TR1; used in cascaded or mirrored configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated NPN transistors | Zero mutual interference between TR1 and TR2 enables independent signal paths in compact layouts. |
| Low VCE(sat) | ≤300 mV at full rated current reduces conduction loss and improves efficiency in battery-powered switches. |
| High hFE consistency | Minimum 110 gain at 2 mA ensures predictable turn-on behavior across production lots and temperature ranges. |
| FR4-optimized thermal design | Per-device Ptot = 300 mW with defined solder pad footprint supports reliable operation without heatsinking. |
Applications
| LED Driver Pair | Level-Shifting Interface |
|---|---|
Use Scenario: Driving dual-color indicator LEDs with independent anode/cathode control in portable instrumentation. IC Role / Device Role / Timing Role: Discrete NPN switch pair providing low-side current sinking for red/green LEDs with shared microcontroller GPIO. Use Value: Eliminates need for two separate SOT23 packages, reducing board area by 40% while maintaining electrical isolation between channels. |
Use Scenario: Converting 3.3 V logic signals to 5 V levels for legacy peripherals in industrial controllers. IC Role / Device Role / Timing Role: Dual-transistor level shifter where TR1 inverts and TR2 restores polarity, enabling bidirectional translation. Use Value: Achieves <100 ns propagation delay with no external pull-ups required, leveraging matched hFE and VBE characteristics. |
| Digital Logic Buffer | Audio Preamp Stage |
Use Scenario: Strengthening weak CMOS outputs to drive multiple TTL inputs in embedded test fixtures. IC Role / Device Role / Timing Role: Non-inverting buffer using TR1 as emitter follower and TR2 as active load for improved linearity. Use Value: Delivers >10 mA sink/source capability with <50 mV output impedance, supporting fan-out of ≥8 TTL loads. |
Use Scenario: Low-noise preamplification of electret microphone signals in voice-enabled IoT sensors. IC Role / Device Role / Timing Role: Common-emitter amplifier stage with TR1 for gain and TR2 for DC bias stabilization via emitter degeneration. Use Value: Provides 35 dB voltage gain at 1 kHz with THD <0.5% at 100 mVpp, enabled by tight hFE matching and low Cc (1.5 pF). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847S,115 | Higher hFE range (200–450 vs. 110–220); identical VCEO, IC, and package. | Better suited for low-drive applications like sensor interface amplifiers where base current must be minimized. | Select BC847S when higher gain stability at low IC (<1 mA) is required; avoid if tighter hFE tolerance is needed for matched pairs. |
| MMBT3904DW | Lower VCEO (40 V), same IC (100 mA), but higher VCE(sat) (300–400 mV) and lower fT (300 MHz typical). | Limited to ≤30 V systems; less suitable for 5 V rail-to-rail switching due to reduced voltage margin. | Choose MMBT3904DW only for cost-sensitive, non-critical 3.3 V logic buffering where gain variation is acceptable. |
Compared with BC846S/DG/B2,115, BC847S offers superior gain for ultra-low-drive circuits, while MMBT3904DW trades voltage headroom and saturation performance for broader distributor availability - making BC846S the optimal balance of robustness, thermal margin, and dual-isolation integrity.

FAQ
Is BC846S/DG/B2,115 pin-compatible with BC847S,115?
Yes - both share identical SOT363-3 pinout (E1-B1-C2-E2-B2-C1), same mechanical dimensions, and compatible solder footprint. Electrical differences exist in hFE range and VBE distribution, so functional substitution requires verification of gain-dependent bias networks.
What is the maximum allowable pulsed collector current for BC846S/DG/B2,115?
The peak collector current rating is 200 mA per transistor under single-pulse conditions (tp ≤ 1 ms). This value is validated per IEC 60134 limiting values and assumes proper PCB thermal relief; sustained operation above 100 mA requires derating per Fig. 1 power curves.
Can BC846S/DG/B2,115 be used in linear amplifier configurations?
Yes - its fT = 100 MHz, low Cc = 1.5 pF, and stable hFE over IC = 0.1–100 mA support Class-A and Class-AB audio preamplifier stages up to 20 kHz, provided VCE is maintained ≥1 V and junction temperature stays below 150 °C.
Does BC846S/DG/B2,115 have automotive qualification?
No - this part is not AEC-Q101 qualified. The datasheet explicitly states "Non-automotive qualified products" and prohibits use in safety-critical or life-support systems. For automotive applications, Nexperia offers the BC846B-Q series with full qualification and extended temperature validation.
