Product details
Overview
BC847BV from Nexperia is an NPN general-purpose double transistor in a SOT666 ultra-small flat-lead package, integrating two matched NPN transistors (TR1 and TR2) for compact dual-switching or amplification. It delivers VCEO = 45 V, IC = 100 mA per transistor, hFE = 200–450 at 2 mA/5 V, and low Cc = 1.5 pF - enabling space-constrained signal conditioning in portable power management circuits.
For engineers reviewing the BC847BV datasheet, BC847BV pinout, BC847BV application, or BC847BV equivalent, key selection criteria include dual-transistor integration in 1.6 mm × 1.2 mm footprint, verified thermal resistance of 416 K/W (per device), and validated performance across −55 °C to 150 °C ambient range with reflow-solder-only mounting.
Technical Context
The BC847BV implements two independent NPN bipolar junction transistors in a single monolithic die housed in a 6-pin SOT666 package. Each transistor shares no internal connection - pinning isolates E1/B1/C1 for TR1 and E2/B2/C2 for TR2, supporting discrete dual-channel control without cross-coupling.
Its design targets board-area reduction versus dual SC-75 devices, enabled by straight-leaded coplanarity (0.08 mm max lead height variation) and optimized FR4 thermal dissipation (Ptot = 300 mW at Tamb ≤ 25 °C). The low 1.5 pF collector capacitance and 100 MHz fT support stable operation up to mid-frequency switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V maximum - supports rail-to-rail switching in 3.3 V and 5 V logic-level systems without breakdown risk. |
| IC (per transistor) | 100 mA continuous - sufficient for driving LEDs, small relays, or logic-level MOSFET gates in portable electronics. |
| hFE | 200–450 at 2 mA/5 V - ensures reliable current amplification with minimal base drive in bias-sensitive analog stages. |
| Cc | 1.5 pF at 10 V - reduces high-frequency signal loss and improves stability in RC-coupled amplifier inputs. |
| Rth(j-a) (per device) | 416 K/W on FR4 PCB - enables sustained 300 mW dissipation without heatsinking in standard consumer-grade layouts. |
| VBE(sat) | 755 mV typical at 10 mA/0.5 mA - minimizes base drive power loss in saturated-switch applications. |
Pinout & Package
SOT666 package: 1.6 mm × 1.2 mm × 0.55 mm body, 0.5 mm pitch, 6 leads, flat leads with excellent coplanarity (≤0.08 mm).
| 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 <200 µA drive for full saturation at 100 mA. |
| 3 | Collector of TR2 | High-side output node for second transistor; rated for 45 V and 100 mA switching duty. |
| 4 | Emitter of TR2 | Independent emitter reference for TR2; electrically isolated from E1 to support floating or differential configurations. |
| 5 | Base of TR2 | Separate control input for TR2; enables asynchronous dual-gating without shared base routing. |
| 6 | Collector of TR1 | Primary output node for TR1; compatible with open-collector logic interfacing and active pull-down networks. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN integration | Replaces two discrete SC-75 transistors, reducing PCB area by >40% and eliminating two pick-and-place operations. |
| Ultra-thin SOT666 package | 0.55 mm profile enables use in slim-profile wearables and stacked-module assemblies where Z-height is constrained. |
| Low collector capacitance | 1.5 pF minimizes Miller effect, preserving bandwidth in 100 MHz small-signal amplifiers and RF detector front-ends. |
| Flat-lead thermal enhancement | 416 K/W Rth(j-a) improves power handling over bent-lead packages, allowing 300 mW total dissipation without derating. |
Applications
| LED Driver Pair | Level-Shifting Switch Pair |
|---|---|
|
Use Scenario: Dual-color LED control in smart sensor nodes requiring independent anode/cathode switching. IC Role / Device Role / Timing Role: Two independent NPN switches driving red/green LEDs from separate GPIOs with common cathode grounding. Use Value: Eliminates need for two separate SOT-23 transistors, saving 2.2 mm² board area and simplifying layout routing. |
Use Scenario: Bidirectional level translation between 1.8 V microcontroller I/O and 3.3 V peripheral bus lines. IC Role / Device Role / Timing Role: One transistor acts as pull-up switch (active-low enable), the other as pull-down switch (active-high disable) in open-drain configuration. Use Value: Enables clean voltage-domain isolation with <10 ns propagation delay and no external bias resistors required. |
| Current Mirror Reference | Audio Preamp Input Stage |
|
Use Scenario: Precision current mirroring in battery-powered gas sensor analog front-ends. IC Role / Device Role / Timing Role: Matched NPN pair (TR1/TR2) configured as emitter-coupled current mirror with shared base bias. Use Value: Achieves <5% current ratio error across −40 °C to 85 °C due to monolithic matching and low VBE drift. |
Use Scenario: Low-noise preamplifier stage for MEMS microphone signals in hearing aids. IC Role / Device Role / Timing Role: TR1 configured as common-emitter amplifier, TR2 as active load for improved gain linearity. Use Value: Delivers 32 dB voltage gain with THD <0.8% at 1 kHz using only passive emitter degeneration and no op-amp. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B,315 | Single NPN in SOT23; identical per-transistor specs but no dual integration. | Requires two placements for dual function; increases board area by 2.8 mm² and adds routing complexity. | Select when dual-transistor matching is unnecessary and layout flexibility outweighs space savings. |
| MBT3904DW1T1G | ON Semiconductor dual NPN in SOT-363; same pinout (SOT666-compatible), but hFE = 100–300 and Ptot = 200 mW. | Lower gain and power rating limit use in high-current or precision current-mirror designs. | Select when cost sensitivity dominates and 100 mA/45 V margin is sufficient for target load. |
Compared with BC847BV, BC847B,315 lacks integrated dual functionality and increases assembly cost, while MBT3904DW1T1G trades off gain consistency and thermal headroom for broader distributor availability - making BC847BV optimal for space- and matching-critical dual-switch designs.

FAQ
Is BC847BV pin-compatible with BC847B in SOT23?
No. BC847BV uses a 6-pin SOT666 package with interleaved emitter/base/collector assignments for two transistors, whereas BC847B is a single-transistor 3-pin SOT23 device. Pin mapping, footprint, and circuit topology are incompatible - direct replacement requires PCB redesign and netlist updates.
Can BC847BV operate at 125 °C ambient temperature?
Yes. The BC847BV is rated for Tamb from −65 °C to +150 °C. At 125 °C ambient, its maximum allowable Ptot drops to approximately 180 mW (derated from 300 mW at 25 °C) based on Rth(j-a) = 416 K/W and Tj(max) = 150 °C, ensuring safe operation under sustained industrial conditions.
What is the recommended soldering method for BC847BV?
Reflow soldering is the only recommended method per Nexperia's datasheet. Wave or hand soldering is not qualified due to thermal stress risks from the ultra-thin 0.55 mm package and fine 0.5 mm pitch. Reflow profiles must comply with JEDEC J-STD-020 Class 3 guidelines, with peak temperature ≤260 °C and time above 217 °C limited to 60–150 seconds.
Does BC847BV have automotive qualification?
No. Per Nexperia's revision history and legal disclaimers, BC847BV is explicitly marked as non-automotive qualified. It has not undergone AEC-Q101 stress testing or PPAP documentation, and its reliability data applies only to commercial/industrial environments - not safety-critical automotive subsystems.
