Product details
Overview
BC847BLP4-7 from Diodes Incorporated is a 45V NPN small-signal transistor in X2-DFN1006-3 package, rated for 100mA collector current and 400mW power dissipation (on standard PCB), with DC current gain hFE of 200–450 at VCE = 5V/IC = 2mA, used in compact load switching and signal amplification circuits in space-constrained consumer and industrial PCBs.
For engineers reviewing the BC847BLP4-7 datasheet, BC847BLP4-7 pinout, BC847BLP4-7 application, or BC847BLP4-7 equivalent, key selection criteria include its 0.4mm height, JEDEC-qualified reliability, 4kV HBM ESD rating, and complementary PNP pairing with BC857BLP4 for push-pull designs.
Technical Context
This NPN bipolar junction transistor operates in linear and saturation regions with verified VCE(sat) ≤ 250 mV at IC = 100 mA/IB = 5 mA and fT = 100 MHz at VCE = 5 V/IC = 10 mA, supporting high-speed switching and RF-coupled amplification up to low-VHF bands.
Its X2-DFN1006-3 package features an exposed collector pad thermally coupled to PCB copper, delivering RθJL = 120 °C/W and enabling stable operation from –55°C to +150°C ambient, with moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown under operating conditions |
| IC | 100 mA - Continuous DC collector current handling capacity without thermal derating on standard layout |
| hFE | 200–450 - DC current gain range at 5 V VCE, 2 mA IC; determines base drive sizing for switching applications |
| VCE(sat) | ≤250 mV - Saturation voltage at 100 mA IC/5 mA IB; directly impacts conduction loss in switch mode |
| fT | 100 MHz - Unity-gain frequency; sets upper limit for small-signal amplification bandwidth |
| ESD HBM | 4,000 V - Human Body Model robustness; reduces need for external protection in assembly and handling |

Pinout & Package
Package: X2-DFN1006-3 - ultra-compact 0.95 mm × 0.65 mm footprint, 0.4 mm max height, with exposed collector pad for thermal and electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitter terminal | Current sink node; connected to ground or low-side reference in common-emitter configurations |
| Pin 2 (Base) | Control input | Low-impedance gate for bias current; requires series resistor to limit IB and prevent overdrive |
| Pin 3 (Collector) | Output/load connection | Exposed metal pad - electrically and thermally tied to collector; must be soldered to PCB copper pour |
Key Features

Applications
| LED Driver Circuit | Level-Shifting Interface |
|---|---|
Use Scenario: Driving discrete indicator LEDs in battery-powered handheld devices where board space is limited. IC Role / Device Role / Timing Role: NPN switch controlling LED anode current path with fast turn-on/turn-off response. Use Value: Low VCE(sat) minimizes voltage drop across transistor, preserving battery life and reducing heat generation in sealed enclosures. | Use Scenario: Translating 1.8 V logic signals to 3.3 V domains in mixed-voltage microcontroller peripherals. IC Role / Device Role / Timing Role: Active-low level shifter using common-emitter configuration with pull-up resistors. Use Value: Verified hFE ≥ 200 ensures reliable saturation at low base drive, maintaining clean logic edges up to 10 MHz. |
| Load Switch for Sensor Modules | Audio Signal Amplifier Stage |
Use Scenario: Power gating analog sensor subcircuits (e.g., temperature or humidity ICs) to reduce system standby current. IC Role / Device Role / Timing Role: High-side or low-side load switch controlled by MCU GPIO, leveraging low leakage ICBO ≤ 15 nA. Use Value: Sub-µA off-state current prevents parasitic drain, extending battery runtime in always-on sensing nodes. | Use Scenario: Pre-amplifying weak microphone signals in voice-activated edge devices before ADC sampling. IC Role / Device Role / Timing Role: Common-emitter small-signal amplifier biased at 2 mA IC for optimal linearity and noise performance. Use Value: fT = 100 MHz supports wideband audio fidelity up to 20 kHz with minimal phase distortion and gain roll-off. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN small-signal transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B,215 (Nexperia) | SOT-23 package (2.9 mm × 1.3 mm); higher RθJA = 370 °C/W; hFE = 200–450 same range | Larger footprint limits use in ultra-dense layouts; better suited for manual rework or prototyping | Select when board real estate allows larger package and thermal management uses standard pads |
| MMBT3904LT1G (ON Semiconductor) | Same X2-DFN1006-3 footprint; VCEO = 40 V (5 V lower); hFE = 100–300 (lower gain spread) | Marginally lower voltage headroom; less consistent gain control at low IC makes biasing more sensitive | Choose only if 40 V rating suffices and cost optimization outweighs gain stability requirements |
Compared with BC847B,215 and MMBT3904LT1G, BC847BLP4-7 delivers superior thermal performance via its exposed collector pad and tighter hFE distribution, making it preferred for production-grade miniaturized designs requiring predictable switching behavior and long-term reliability.

FAQ
What is the maximum allowable collector current for continuous operation?
The BC847BLP4-7 is rated for 100 mA continuous collector current (IC) under standard thermal conditions (2 oz copper, still air). At 100 mA with IB = 5 mA, VCE(sat) remains ≤250 mV, and junction temperature stays within –55°C to +150°C limits when PCB layout follows recommended pad dimensions and copper area.
Is BC847BLP4-7 suitable for automotive applications?
The BC847BLP4-7 is qualified to JEDEC reliability standards referenced in AEC-Q, but it is not AEC-Q200 certified. For automotive applications, Diodes offers the pin-compatible BC847BLP4Q variant, which undergoes full AEC-Q200 stress testing and is documented in a separate datasheet.
How does the X2-DFN1006-3 package affect thermal design?
The X2-DFN1006-3 package integrates an exposed collector pad that serves as both electrical connection and primary thermal path. When soldered to ≥25 mm² of 2 oz copper, RθJL drops to 120 °C/W-enabling 2.5× higher power dissipation than standard layout-making thermal vias and large copper pours essential for sustained 100 mA operation.
Can BC847BLP4-7 be used as a direct replacement for BC847C in existing designs?
No-BC847BLP4-7 has hFE = 200–450 (B-gain group), while BC847C specifies hFE = 420–800 (C-gain group). Substituting without circuit review risks insufficient drive in high-gain-dependent configurations; verify base resistor values and saturation margins if replacing across gain grades.
