Product details
Overview
BC847AQAZ from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in a leadless DFN1010D-3 (SOT1215) package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 110–220 at IC = 2 mA, VCE = 5 V. It serves as a compact, low-profile switching and amplification device in space-constrained automotive and mobile PCBs.
For engineers reviewing the BC847AQAZ datasheet, BC847AQAZ pinout, BC847AQAZ application, or BC847AQAZ equivalent, this part supports AOI-compatible solder joint inspection, operates across −55 °C to +150 °C ambient, and delivers ≤200 mV VCE(sat) at IC = 100 mA / IB = 5 mA - critical for low-loss signal routing and battery-powered load control.
Technical Context
This discrete NPN bipolar junction transistor uses silicon planar epitaxial construction with base-emitter and collector-base junctions optimized for stable DC gain and low saturation voltage. Its thermal resistance (Rth(j-a)) is 446 K/W on single-layer FR4 and 284 K/W on 4-layer FR4, enabling reliable operation under pulsed loads up to 200 mA ICM.
The device features visible and solderable side pads per SOT1215 footprint, supporting reflow-compatible assembly and automated optical inspection. Its binary marking code "00 10 01" uniquely identifies the BC847AQA variant within the BC847XQA series, distinguishing it from B- and C-gain versions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown; defines rail compatibility in 3.3 V/5 V/12 V logic-level switching. |
| IC | 100 mA continuous - Supports moderate-current digital interface buffering and sensor signal conditioning without external heatsinking. |
| hFE | 110–220 at IC = 2 mA - Tight DC gain binning enables predictable base drive sizing in linear amplifier and switch bias networks. |
| VCE(sat) | 200 mV max at IC = 100 mA / IB = 5 mA - Minimizes conduction loss in high-duty-cycle switching applications like LED drivers or power enable circuits. |
| Tj max | +150 °C - Enables use in under-hood automotive modules and thermally dense portable electronics without derating penalties. |
| Package | DFN1010D-3 (SOT1215), 1.1 × 1.0 × 0.37 mm - Ultra-thin, leadless, AOI-friendly footprint ideal for 0.4 mm pitch routing and ultra-slim end-products. |
Pinout & Package
BC847AQAZ uses the DFN1010D-3 (SOT1215) surface-mount plastic package: 1.1 mm × 1.0 mm body, 0.37 mm height, with three exposed copper terminals on the sides for soldering and optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; accepts 5 mA typical base drive to saturate 100 mA collector current with minimal VBE(sat). |
| 2 | Emitter (E) | Current return path; tied to ground or low-side reference; requires low-inductance layout for fast switching. |
| 3 | Collector (C) | Output terminal; connects to load or supply rail; dual-side pad design ensures robust thermal and electrical connection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, body electronics, and ADAS subsystems. |
| Low profile (0.37 mm) | Enables stacking under shields or integration into <1.2 mm total board thickness designs - critical for smartphones, wearables, and compact ECUs. |
| AOI-compatible side pads | Visible solder joints allow 100% automated optical inspection without X-ray, reducing post-reflow defect escape in high-volume SMT lines. |
| Three hFE bins (A/B/C) | Allows precise gain matching across production lots - simplifies analog circuit calibration and eliminates manual transistor sorting. |
Applications
| Automotive Door Module | Smartphone Power Sequencing |
|---|---|
Use Scenario: Controlling window lift motor enable signals and mirror fold/unfold relays in door control units. IC Role / Device Role / Timing Role: Low-side switch driving 50–80 mA solenoid and LED indicator loads. Use Value: AEC-Q101 compliance ensures lifetime reliability at 125 °C ambient; 200 mV VCE(sat) limits self-heating during repeated actuation cycles. |
Use Scenario: Enabling/disabling PMIC rails or camera sensor power domains during boot and sleep transitions. IC Role / Device Role / Timing Role: Digital logic-level translator and load switch between AP GPIO and 1.8 V/2.8 V peripheral supplies. Use Value: 0.37 mm height avoids interference with stacked memory; 110–220 hFE guarantees clean turn-on/turn-off timing with standard 3.3 V GPIO drive. |
| USB-C Port Protection | Industrial Sensor Interface |
Use Scenario: Isolating VBUS detection and CC line pull-up/pull-down in USB-C receptacles. IC Role / Device Role / Timing Role: Bidirectional level-shifting switch managing 5 V VBUS sensing and 3.3 V controller signaling. Use Value: 45 V VCEO withstands transient overvoltage events; side-pad solderability ensures mechanical integrity during connector mating cycles. |
Use Scenario: Amplifying low-level thermistor or RTD bridge outputs in programmable logic controllers. IC Role / Device Role / Timing Role: Small-signal common-emitter amplifier with fixed-gain bias network. Use Value: 2–10 MHz fT supports kHz-range sensor bandwidth; 100 nA IEBO minimizes input offset error in precision analog front-ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BW | SOT323 package (2.1 × 1.25 × 0.95 mm); higher Rth(j-a) (500 K/W); no AEC-Q101 qualification. | Non-automotive consumer boards where AOI is not required and board height >1.0 mm is acceptable. | Select when cost sensitivity outweighs automotive compliance and ultra-thin packaging needs. |
| MMBT3904LT1G | SOT-23 package (3.0 × 1.4 × 1.0 mm); hFE = 100–300; VCEO = 40 V; not AEC-Q101 qualified. | General-purpose industrial controls and legacy PCBs with larger footprints and relaxed thermal constraints. | Choose if existing SOT-23 land pattern reuse is prioritized over height reduction and automotive qualification. |
Compared with BC847AQAZ, BC847BW trades AEC-Q101 compliance and 0.37 mm height for lower unit cost and wider availability, while MMBT3904LT1G offers broader hFE range but lacks automotive validation and ultra-compact form factor - making BC847AQAZ optimal for next-gen automotive and mobile designs demanding both reliability and miniaturization.

FAQ
What is the maximum allowable junction temperature for BC847AQAZ?
The absolute maximum junction temperature (Tj) is +150 °C, verified per IEC 60134 limiting values. Operation at this limit requires thermal design that maintains Tj ≤150 °C under worst-case ambient and power dissipation conditions - e.g., ≤280 mW Ptot on single-layer FR4 at 25 °C ambient, with appropriate derating above 25 °C.
Does BC847AQAZ support reflow soldering per JEDEC J-STD-020?
Yes - the DFN1010D-3 package is qualified for lead-free reflow per JEDEC J-STD-020D.3, with peak temperature up to 260 °C for ≤30 seconds. The recommended reflow footprint (documented in Figure 18 of the datasheet) specifies 0.35 mm solder lands and 0.45 mm solder resist openings for reliable side-wetted joint formation.
How does the binary marking "00 10 01" identify BC847AQAZ?
The marking "00 10 01" is a unique 6-bit code etched on the top surface, where bits 1–2 = "00", bits 3–4 = "10", bits 5–6 = "01". This code maps exclusively to the BC847AQA variant (hFE = 110–220) within the BC847XQA family, distinguishing it from BC847BQA ("00 10 11") and BC847CQA ("00 11 01") on the same reel.
Can BC847AQAZ replace BC847BQA in an existing design?
No - BC847AQAZ has hFE = 110–220, while BC847BQA is binned at 200–450. Substituting without circuit review risks insufficient base drive margin, leading to incomplete saturation or increased VCE(sat). If gain reduction is acceptable, verify IB ≥ IC/110 and confirm VCE(sat) remains ≤200 mV at operating IC.
