Product details
Overview
BC847BLP-7B from Diodes Incorporated is a 45V NPN small-signal transistor in X1-DFN1006-3 package, rated for 100mA collector current and 400mW power dissipation (on standard PCB), with DC current gain hFE of 200–450 at 2mA/5V. It delivers low VCE(sat) (80–600mV) across operating currents and supports automotive-grade variants via Q-suffix qualification.
For engineers reviewing the BC847BLP-7B datasheet, BC847BLP-7B pinout, BC847BLP-7B application, or BC847BLP-7B equivalent, key selection criteria include its 0.60mm² footprint, 0.5mm height, JEDEC-qualified reliability, complementary PNP pairing (BC857BLP), and thermal resistance (RθJA = 310°C/W on minimal pad layout).
Technical Context
This NPN bipolar junction transistor operates in linear amplification and switching modes, with verified breakdown voltages of VCBO = 50V and VCEO = 45V, and ESD robustness per JEDEC HBM Class 3A (4kV). Its fT = 100MHz enables RF-coupled signal conditioning up to low-VHF bands.
The device uses NiPdAu-plated terminals for solderability per MIL-STD-202, Method 208, and features an exposed collector pad thermally coupled to PCB copper - enabling RθJL = 120°C/W when mounted on 25mm × 25mm 2oz copper, critical for thermal management in space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45V - maximum safe collector-emitter voltage before avalanche conduction in common-emitter configuration |
| IC | 100mA continuous - usable for load switching or pre-driver stages in portable power management |
| hFE | 200–450 @ 2mA/5V - stable current amplification across production lots for biasing and analog gain circuits |
| VCE(sat) | 80–600mV @ IC/IB = 10mA/0.5mA to 100mA/5mA - enables low-loss switching in battery-powered logic interfaces |
| fT | 100MHz @ 5V/10mA - supports high-speed digital signal buffering and RF detector front-ends |
| RθJA | 310°C/W on minimal 2oz FR4 pad - defines thermal derating limit for ambient operation up to +85°C without forced cooling |
| ESD HBM | 4,000V - meets IEC 61000-4-2 Level 4 immunity requirements for handheld and industrial control inputs |
Pinout & Package
Package: X1-DFN1006-3 - ultra-compact 0.60mm² footprint, 0.5mm profile, with exposed collector pad for thermal and electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |

| 3 (Collector) | Output/Power node | Exposed metal pad - electrically and thermally connected to PCB copper; carries switched load current |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 0.60mm² area - reduces PCB real estate by 13× vs. SOT23, enabling dense mixed-signal layouts |
| Thermally enhanced leadframe | Exposed collector pad with RθJL = 120°C/W - improves power handling in compact power regulators and LED drivers |
| High-reliability qualification | JEDEC-compliant and AEC-Q101 ready - supports automotive infotainment and body electronics with PPAP-capable manufacturing |
| Green material system | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) - meets IPC-1752A environmental compliance mandates |
| Complementary PNP pairing | Matched performance with BC857BLP - simplifies push-pull output stage design in audio amplifiers and level translators |
Applications

Use Value: 600mV max VCE(sat) at 100mA minimizes LED forward-voltage drop error; 0.5mm height avoids interference with optical sensor alignment. |
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 |
|---|---|---|---|
| BC847CWT-7 | SOT-323 package (2.1mm²), higher RθJA = 350°C/W, same hFE range | Larger footprint; less suitable for ultra-dense layouts but easier hand-soldering | Select when manual rework or legacy board compatibility outweighs size constraints |
| MMBT3904LT1G | SOT-23 package (2.8mm²), VCEO = 40V, hFE = 100–300, lower ESD rating (2kV HBM) | Lower voltage margin and gain spread; widely available but not AEC-Q101 qualified | Select for cost-sensitive consumer applications where 40V rating suffices and automotive qualification is unnecessary |
Compared with BC847CWT-7 and MMBT3904LT1G, BC847BLP-7B offers the smallest footprint, highest voltage margin (45V), and strongest ESD resilience (4kV HBM), making it optimal for next-generation space-constrained and automotive-adjacent designs requiring thermal efficiency and reliability.

FAQ
What is the thermal resistance of BC847BLP-7B under standard PCB conditions?
The junction-to-ambient thermal resistance (RθJA) is 310°C/W when mounted on a minimum recommended 2oz copper pad on a single-sided 1.6mm FR4 PCB under still-air conditions. With an expanded 25mm × 25mm 2oz copper area under the exposed collector pad, RθJA improves to 120°C/W, significantly increasing allowable power dissipation.
Is BC847BLP-7B suitable for automotive applications?
Yes - BC847BLP-7B is JEDEC-qualified for high reliability and serves as the base variant for AEC-Q101-qualified automotive versions (Q-suffix parts). While this specific part is not automotive-grade certified, its process, testing, and packaging meet foundational requirements for automotive use, and Diodes provides PPAP-capable manufacturing in IATF 16949-certified facilities.
How does the X1-DFN1006-3 package affect soldering and rework?
The X1-DFN1006-3 uses NiPdAu-plated terminals and is rated for moisture sensitivity level 1 (MSL-1), permitting unlimited floor life before reflow. Its 0.35mm pitch and exposed collector pad require stencil-controlled solder paste deposition and infrared reflow profiling - not recommended for hand-soldering due to thermal mass imbalance and risk of tombstoning.
What is the meaning of the '1F' marking on BC847BLP-7B?
The '1F' top-side laser marking identifies the device as the BC847BLP product type per Diodes' internal coding system. It is not a date code or lot identifier. The bar adjacent to '1F' denotes the base-emitter side of the package, aiding orientation during automated placement and visual inspection.
