Product details
Overview
BC847B-QVL from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in SOT23 (TO-236AB) package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 200–450 at VCE = 5 V, IC = 2 mA. It serves as a low-voltage switching and linear amplification device in automotive body control modules, sensor interface stages, and LED driver bias circuits.
For engineers reviewing the BC847B-QVL datasheet, BC847B-QVL pinout, BC847B-QVL application, or BC847B-QVL equivalent, key selection criteria include its automotive qualification, gain binning consistency (B-grade), thermal resistance (500 K/W on FR4), and saturation voltage performance under 100 mA load conditions.
Technical Context
This transistor operates as a discrete bipolar junction device with fixed NPN polarity, optimized for stable DC current amplification and low-saturation switching in ambient temperatures from −65 °C to +150 °C. Its base-emitter voltage (VBE) is specified at 580–700 mV and exhibits a −2 mV/K temperature coefficient.
The device complies with IEC 60134 absolute maximum ratings, including 45 V collector-emitter breakdown (V(BR)CEO), 6 V emitter-base rating (V(BR)EBO), and 250 mW total power dissipation on standard FR4 PCB. Thermal impedance data supports pulsed operation up to 1 ms with defined duty cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before avalanche breakdown; defines upper rail limit in 12 V/24 V automotive supply interfaces. |
| IC | 100 mA continuous - Rated collector current for sustained linear or switching operation without thermal derating on standard FR4 board. |
| hFE | 200–450 @ VCE = 5 V, IC = 2 mA - Tight B-bin DC current gain range ensures predictable base drive requirements in amplifier and switch bias networks. |
| VCE(sat) | 200–400 mV @ IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes conduction loss in high-duty-cycle switching applications like relay drivers. |
| Ptot | 250 mW @ Tamb ≤ 25 °C - Power handling capacity on single-sided tin-plated FR4 PCB; requires thermal derating above 25 °C ambient. |
| Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance under defined PCB mounting; determines temperature rise per watt dissipated. |
| AEC-Q101 | Qualified - Meets stress test requirements for discrete semiconductors in automotive applications, including temperature cycling and HTRB. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads, 1.9 mm × 1.1 mm footprint, 0.9 mm height, and gull-wing lead form for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; accepts forward-biased current to enable conduction between collector and emitter; requires current-limiting resistor in most bias configurations. |
| 2 | Emitter (E) | Current sink node; connected to circuit ground or low-side reference; forms common-emitter configuration with collector output. |
| 3 | Collector (C) | Output terminal; delivers amplified current or switched load current; placed at higher potential than emitter during active/saturation modes. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 compliant - Validated for use in engine control units, lighting modules, and infotainment power management where reliability under thermal and vibration stress is critical. |
| Gain binning | B-grade hFE = 200–450 - Enables consistent base resistor selection across production lots without recalibration in analog front-end amplifiers. |
| Low VCE(sat) | ≤ 400 mV @ 100 mA - Reduces power loss and self-heating in always-on bias circuits such as sensor signal conditioning stages. |
| Thermal robustness | Tj max = 150 °C - Supports operation in under-hood environments and enclosed enclosures without forced cooling. |
| Small-footprint packaging | SOT23 outline - Enables high-density PCB layouts in space-constrained automotive ECUs and portable industrial controllers. |

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 |
|---|---|---|---|
| BC847B,115 (Nexperia) | Non-automotive grade; same electrical specs but not AEC-Q101 qualified. | Acceptable for industrial or consumer products without automotive reliability requirements. | Select when cost sensitivity outweighs automotive qualification needs and lifecycle assurance is not mandated. |
| MMBT3904LT1G (onsemi) | hFE = 100–300 (lower max gain); VCEO = 40 V; same SOT23 package. | Marginally lower voltage headroom and gain spread may require redesign of base bias network in precision amplifiers. | Choose when legacy design compatibility with MMBT3904 footprint is required and 40 V rating suffices. |
Compared with BC847B-QVL, BC847B,115 lacks automotive qualification and long-term supply assurance, while MMBT3904LT1G trades gain consistency and voltage margin for broader distributor availability-making BC847B-QVL optimal for new automotive designs requiring guaranteed reliability and parametric stability.

FAQ
What is the maximum allowable junction temperature for BC847B-QVL?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation at this temperature requires full derating of power dissipation and verification of thermal layout on the target PCB, especially under sustained 100 mA load conditions.
How does the BC847B-QVL differ from the standard BC847B in marking and qualification?
BC847B-QVL carries "1F%" top-side marking (where % is site code) and is explicitly qualified to AEC-Q101 Rev. G. Standard BC847B (e.g., BC847B,115) uses identical marking but lacks automotive qualification documentation and stress-test validation, limiting its use in automotive production.
Can BC847B-QVL be used in linear amplifier configurations?
Yes-it is characterized for DC current gain (hFE) across collector currents from 10 µA to 100 mA and supports stable operation in common-emitter amplifier topologies with VCE ≥ 1 V, provided thermal limits and VCEO ratings are observed in the final circuit design.
What is the typical transition frequency (fT) of BC847B-QVL?
The typical transition frequency is 100 MHz at VCE = 5 V, IC = 10 mA, and f = 100 MHz. This value supports audio-frequency amplification and low-speed digital switching but is not intended for RF or high-speed data line applications.
