Product details
Overview
BC847BS/DG/B2,115 from Nexperia is a dual NPN general-purpose transistor pair in SOT363-3 (TSSOP6) package, rated for 45 V VCEO, 100 mA IC, and featuring matched hFE (200–450), low VCE(sat) (≤300 mV @ 100 mA), and isolated operation with no mutual interference-used in compact signal switching and biasing circuits on space-constrained PCBs.
For engineers reviewing the BC847BS/DG/B2,115 datasheet, BC847BS/DG/B2,115 pinout, BC847BS/DG/B2,115 application, or BC847BS/DG/B2,115 equivalent, this dual-transistor device supports high-density analog and digital interface design where matched gain, low saturation voltage, and thermal independence between channels are critical selection criteria.
Technical Context
The BC847BS integrates two electrically isolated NPN transistors in a single TSSOP6 package, sharing no internal connection-enabling independent biasing and switching without crosstalk. Each transistor exhibits tightly controlled DC current gain (hFE = 200–450 at VCE = 5 V, IC = 2 mA) and low collector capacitance (Cc ≤ 1.5 pF).
It operates within −65 °C to 150 °C ambient range, with per-transistor power dissipation up to 220 mW on standard FR4 and 250 mW with enhanced thermal pad layout. Thermal resistance Rth(j-a) is 568 K/W (standard footprint) and 500 K/W (enhanced pad), supporting reliable performance in thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V logic and sensor interface rails. |
| IC | 100 mA - Continuous collector current rating; supports driving small relays, LEDs, and logic-level MOSFET gates. |
| hFE | 200–450 - DC current gain range at 2 mA collector current; ensures predictable base drive requirements across production lots. |
| VCE(sat) | ≤300 mV @ IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications. |
| Cc | ≤1.5 pF @ VCB = 10 V - Low collector capacitance preserves high-frequency response up to 100 MHz fT. |
| Rth(j-a) | 568 K/W - Junction-to-ambient thermal resistance on standard FR4; informs derating curves for sustained 100 mA operation. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering with defined solder paste stencil openings (0.5 mm × 0.5 mm for pins 1–4, 0.6 mm × 0.6 mm for pins 5–6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects directly to ground or load return path. |
| 2 | Base of TR1 | Control input for TR1; requires ~0.65 V forward bias and precise current limiting for linear or saturated operation. |
| 3 | Collector of TR2 | High-side output node for second transistor; routed to supply rail or active load in common-emitter configuration. |
| 4 | Emitter of TR2 | Independent current sink for TR2; electrically isolated from E1 to prevent inter-channel coupling. |
| 5 | Base of TR2 | Separate control input for TR2; enables asynchronous switching or differential pair biasing without shared base impedance. |
| 6 | Collector of TR1 | Primary output node for TR1; used in amplification, level-shifting, or low-side switching with minimal VCE(sat) loss. |
Key Features
| Feature | Design Value |
|---|---|
| Matched hFE pair | Both transistors exhibit 200–450 gain under identical test conditions-reduces calibration overhead in dual-path analog circuits. |
| No mutual interference | Electrically isolated die structure eliminates crosstalk; essential for noise-sensitive bias networks and precision current mirrors. |
| Low VCE(sat) | ≤300 mV at full 100 mA load-cuts conduction loss by >50% vs. legacy general-purpose transistors, improving efficiency in battery-powered systems. |
| Reduced board space | Dual-transistor integration replaces two discrete SOT23 devices, saving ≥40% PCB area and reducing assembly cost. |
| Low collector capacitance | ≤1.5 pF enables stable operation beyond 100 MHz fT; suitable for RF detector stages and fast-switching digital interfaces. |
Applications
| LED Driver Circuit | Level-Shifting Interface |
|---|---|
|
Use Scenario: Driving dual-color indicator LEDs from 3.3 V microcontroller GPIOs with independent on/off control. IC Role / Device Role / Timing Role: Dual NPN switch providing low-side current sinking for red/green LED anodes tied to 5 V rail.

| Current Mirror Bias | Compact Relay Driver |
|
Use Scenario: Generating matched reference currents for op-amp input stage biasing in portable instrumentation. IC Role / Device Role / Timing Role: Precision current mirror pair with shared base resistors and separate emitters for thermal tracking. Use Value: Identical process and layout yield <±3% current mismatch; low Cc prevents phase shift in feedback paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPDW1T3G | Same hFE range and VCEO, but in SOT-363 package with different marking and moisture sensitivity level (MSL3 vs MSL1). | Identical electrical specs; differs only in JEDEC-compliant packaging and humidity handling-no circuit redesign needed. | Select when requiring RoHS-compliant tape-and-reel delivery with certified MSL3 handling for high-volume SMT lines. |
| MBT3904DW1T1G | Lower VCEO (40 V), higher VCE(sat) (max 400 mV), wider hFE spread (100–300), and larger SOT-363 footprint (2.2 mm × 1.35 mm same, but thicker profile). | Marginally lower voltage headroom and less consistent gain matching-suitable only where 40 V rating suffices and gain tolerance >±30% is acceptable. | Choose only if BC847BS/DG/B2,115 is unavailable and system voltage remains ≤36 V with relaxed gain stability requirements. |
Compared with BC847BS/DG/B2,115, BC847BPDW1T3G offers identical performance with standardized packaging compliance, while MBT3904DW1T1G trades voltage margin and gain consistency for broader vendor availability-making the original the optimal choice for precision dual-transistor functions.

FAQ
What is the maximum continuous collector current per transistor in BC847BS/DG/B2,115?
The absolute maximum continuous collector current per transistor is 100 mA at Tamb ≤ 25 °C with proper PCB thermal relief. Derating is required above 25 °C per the 568 K/W junction-to-ambient thermal resistance curve-e.g., 60 mA at 75 °C ambient on standard FR4 layout.
Can BC847BS/DG/B2,115 replace two discrete BC847B transistors in existing designs?
Yes-its pinout matches the dual-transistor functional equivalent of two BC847B SOT23 devices, with identical VCEO, hFE, and VCE(sat) specs. However, PCB layout must accommodate the SOT363-3 footprint (2.2 mm × 1.35 mm) instead of two separate 2.9 mm × 1.3 mm pads.
Is BC847BS/DG/B2,115 suitable for automotive applications?
No-this part is not AEC-Q101 qualified and lacks automotive-specific testing or qualification documentation. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use only in commercial, industrial, or consumer equipment.
What does the '/DG/B2,115' suffix indicate in the full part number?
The '/DG' denotes Nexperia's specific tape-and-reel packaging variant (1000 pcs/reel, 8 mm carrier tape), 'B2' indicates manufacturing lot code, and ',115' refers to date code (week 15 of 2022); all are traceability identifiers-not functional or parametric modifiers.
