Product details
Overview
BC847BQBZ from Nexperia is an AEC-Q101 qualified NPN general-purpose transistor in a leadless DFN1110D-3 (SOT8015) package, delivering 45 V VCEO, 100 mA IC, and hFE of 200–450 at VCE = 5 V / IC = 2 mA. It serves as a compact, high-reliability switching and amplification device in space-constrained automotive and industrial PCBs.
For engineers reviewing the BC847BQBZ datasheet, BC847BQBZ pinout, BC847BQBZ application, or BC847BQBZ equivalent, this part supports AOI-compatible solder joint inspection, operates up to 150 °C junction temperature, and provides side-wettable flanks for reliable reflow soldering on FR4 PCBs with 35–70 µm copper.
Technical Context
This transistor uses epitaxial planar silicon technology with a base-emitter junction optimized for stable DC current gain across −55 °C to +150 °C ambient. Its low 0.48 mm profile and 1.1 × 1.0 mm footprint enable high-density placement in automotive body control modules and sensor interface circuits.
The device features defined absolute maximum ratings including 50 V VCBO, 6 V VEBO, and 420 mW Ptot on 70 µm copper FR4 - with thermal resistance Rth(j-a) of 298 K/W under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines safe operating range in 24 V automotive switching rails. |
| IC | 100 mA continuous - Rated collector current enabling direct drive of small relays, LEDs, or logic-level signal buffers without external heat sinking. |
| hFE | 200–450 at VCE = 5 V, IC = 2 mA - High and tightly binned DC current gain ensures predictable base drive requirements in linear and saturated switch modes. |
| VCE(sat) | ≤ 400 mV at IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes power loss and self-heating during high-duty-cycle switching. |
| Package | DFN1110D-3 (SOT8015) - 1.1 × 1.0 × 0.48 mm leadless package with side-wettable flanks for automated optical inspection and IPC-compliant reflow. |
| AEC-Q101 | Qualified - Certified for automotive applications per stress test standard, supporting use in non-safety-critical vehicle subsystems. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, ultra-thin, leadless plastic package with side-wettable flanks, measuring 1.1 mm × 1.0 mm × 0.48 mm and featuring a 0.65 mm pitch. Its low 0.5 mm height enables stacking and tight layout in portable and automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal accepting TTL/CMOS-compatible base current to bias the transistor into active or saturation region. |
| 2 | Emitter (E) | Current return path tied to ground or low-side reference; forms common-emitter configuration with defined VBE threshold (~650–770 mV). |
| 3 | Collector (C) | High-side output node handling up to 45 V and 100 mA load current; connected to switched loads such as sensors or indicator LEDs. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability, including temperature cycling, HTRB, and ESD testing - suitable for under-hood and cabin modules. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing post-reflow defect escape in high-volume SMT lines. |
| Ultra-small footprint | 1.1 × 1.0 mm area - saves >50% board space versus legacy SOT23 packages, critical for multi-sensor IoT nodes and compact ADAS subassemblies. |
| Low thermal resistance | Rth(j-a) = 298 K/W on 70 µm FR4 - allows sustained 100 mA operation at +85 °C ambient without derating in thermally constrained layouts. |
Applications
| Automotive Door Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Driving window lift motor control logic and LED status indicators in door control units. IC Role / Device Role / Timing Role: NPN switch enabling microcontroller GPIO to sink up to 100 mA for relay coil activation and LED current limiting. Use Value: AEC-Q101 qualification and 150 °C Tj rating ensure long-term reliability in sealed, thermally isolated door cavities. |
Use Scenario: Level-shifting and signal conditioning between 3.3 V microcontrollers and 5–24 V field sensors in PLC I/O modules. IC Role / Device Role / Timing Role: General-purpose amplifier and switch providing gain staging and digital isolation in analog front-end signal chains. Use Value: Tight hFE binning (200–450) reduces calibration overhead across production batches in precision sensor systems. |
| Portable Medical Monitor | Smart Home Actuator |
Use Scenario: Controlling piezoelectric buzzer drivers and low-power display backlight segments in battery-powered patient monitors. IC Role / Device Role / Timing Role: Low-VCE(sat) switch minimizing voltage drop and extending battery life during audible alert generation. Use Value: 400 mV VCE(sat) at full load reduces power dissipation to <100 mW, avoiding thermal throttling in sealed enclosures. |
Use Scenario: Driving solenoid valves and small DC fans in smart thermostats and HVAC controllers. IC Role / Device Role / Timing Role: High-gain NPN transistor used in discrete driver stages to amplify MCU PWM signals for actuator control. Use Value: Side-wettable flanks support AOI verification of solder integrity - critical for field-reliable consumer devices with no service access. |
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,115 (Nexperia) | SOT323 package (2.1 × 1.25 mm), higher Rth(j-a) (420 K/W), no side-wettable flanks | Lacks AOI support and occupies >2× board area; suitable only where reflow inspection is manual or waived | Select when legacy SMT lines lack AOI capability or when thermal margin exceeds 298 K/W requirement |
| MMBT3904LT1G (onsemi) | SOT-23 package, VCEO = 40 V, hFE = 100–300, not AEC-Q101 qualified | Lower voltage rating and unqualified for automotive; requires additional qualification effort for vehicle use | Choose for cost-sensitive industrial or consumer designs where AEC-Q101 is not mandated |
Compared with BC847BW and MMBT3904LT1G, BC847BQBZ delivers superior board-area efficiency, guaranteed AOI compatibility, and automotive-grade reliability - making it the optimal choice for new automotive and high-reliability industrial designs requiring compact, verified performance.

FAQ
What is the maximum junction temperature for BC847BQBZ?
The absolute maximum junction temperature (Tj) is 150 °C, validated per AEC-Q101 stress testing. Derating begins above 25 °C ambient, with total power dissipation dropping from 420 mW (70 µm copper FR4) to zero at 150 °C - ensuring safe operation in under-hood environments.
Does BC847BQBZ require special PCB layout considerations?
Yes - the DFN1110D-3 package requires precise stencil design (0.1 mm thickness recommended) and solder paste volume control to ensure wetting of side-wettable flanks. The footprint must match Nexperia's specified land pattern (1.4 mm × 0.65 mm solder lands, 0.34 mm pad width) to pass AOI.
How does BC847BQBZ differ from BC847BQBA?
BC847BQBZ is the tape-and-reel packaged version (SOT8015) with marking code "A3", while BC847BQBA denotes the same die in bottom-side marked format - both share identical electrical specs, thermal limits, and AEC-Q101 qualification. The suffix denotes packaging variant, not functional difference.
Can BC847BQBZ replace BC847B in existing SOT23 designs?
No - BC847BQBZ uses DFN1110D-3 (SOT8015), which is not pin-to-pin or footprint compatible with SOT23. Direct replacement requires PCB redesign, stencil update, and requalification due to different thermal behavior, solder joint geometry, and mounting method.
