Product details
Overview
BC847C-QVL from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in SOT23 (TO-236AB) package, designed for automotive-grade switching and amplification. It delivers DC current gain (hFE) of 420–800 at VCE = 5 V and IC = 2 mA, supports 45 V collector-emitter breakdown voltage, handles 100 mA continuous collector current, and operates across –65 °C to +150 °C ambient range - used in engine control module signal conditioning stages.
For engineers reviewing the BC847C-QVL datasheet, BC847C-QVL pinout, BC847C-QVL application, or BC847C-QVL equivalent, this page provides verified package mapping, validated thermal performance under FR4 PCB mounting, confirmed automotive qualification status, and real-world gain/saturation behavior at defined bias points.
Technical Context
This transistor operates as a low-voltage, medium-current bipolar junction device with fixed NPN polarity and base-controlled current amplification. Its hFE binning (C-grade) ensures tight gain distribution for consistent switching thresholds in digital logic interfaces and analog preamplifier stages.
Thermal resistance Rth(j-a) is 500 K/W when mounted on standard FR4 PCB with single-sided copper, defining its power handling limit at 250 mW under ambient conditions. Absolute maximum ratings include VCEO = 45 V, VEBO = 6 V, and Tj ≤ 150 °C - aligning with under-hood automotive electronics requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before avalanche breakdown; defines rail compatibility in 12 V/24 V automotive systems. |
| IC | 100 mA - Continuous DC collector current rating; supports relay drivers, LED indicators, and sensor interface loads. |
| hFE | 420–800 @ VCE = 5 V, IC = 2 mA - High and tightly binned DC current gain enables stable biasing in amplifier configurations without feedback trimming. |
| VCE(sat) | 200–400 mV @ IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes power loss and heat generation in switching applications. |
| Ptot | 250 mW @ Tamb ≤ 25 °C - Total power dissipation limit on standard FR4 PCB; sets upper bound for linear-mode operation. |
| Tj(max) | 150 °C - Maximum junction temperature; enables operation in high-temperature engine bay environments. |
| AEC-Q101 | Qualified - Certified for automotive use per stress test standard; supports PPAP documentation and long-term reliability in safety-critical subsystems. |
Pinout & Package
SOT23 (TO-236AB) surface-mount plastic package with 3 leads; dimensions: 2.9 mm × 1.3 mm × 1.0 mm (L × W × H); standard footprint compatible with reflow and wave soldering per IPC-7351.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input terminal; requires ~700 mV forward bias to initiate conduction; drives switching action via IB-to-IC amplification. |
| 2 | Emitter (E) | Reference terminal for bias network; connected to ground or common return path; carries full emitter current (IC + IB). |
| 3 | Collector (C) | Output terminal sourcing load current; reverse-biased during cutoff; sustains up to 45 V potential relative to emitter in active/saturation modes. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine management, body control modules, and lighting systems requiring extended temperature and reliability compliance. |
| Three hFE gain bins (A/B/C) | C-bin offers 420–800 hFE, enabling predictable turn-on behavior in digital switches and reducing need for external gain compensation. |
| Low VCE(sat) | 200–400 mV at rated IC/IB ratio ensures minimal voltage drop across collector-emitter path, improving efficiency in power-switching circuits. |
| FR4-compatible thermal design | Rth(j-a) = 500 K/W on standard PCB allows direct thermal modeling for board-level power budgeting without heatsink requirement. |
| Small-outline SMT packaging | SOT23 footprint reduces board area by >50% vs. TO-92, supporting high-density layouts in space-constrained ECUs and ADAS sensors. |

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 |
|---|---|---|---|
| BC847C,115 (Nexperia) | Non-automotive grade; identical electrical specs but lacks AEC-Q101 qualification and extended temperature screening. | Restricted to commercial/industrial use; not approved for automotive ECU deployment or PPAP submission. | Select only for cost-sensitive non-automotive designs where qualification traceability is not required. |
| MMBT4401LT1G (onsemi) | Higher VCEO (40 V), lower hFE (100–300), same SOT23 package; qualified to AEC-Q101 but different gain binning. | Less suitable for precision gain-dependent amplifiers; better for higher-speed switching due to fT = 250 MHz. | Prefer when faster switching or wider VCEO margin is needed, but verify gain stability in bias networks. |
Compared with BC847C-QVL, BC847C,115 omits automotive qualification and lifetime reliability validation, while MMBT4401LT1G trades gain consistency for higher speed and slightly reduced voltage rating - making BC847C-QVL optimal for gain-stable, temperature-resilient automotive switching where qualification is mandatory.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is 100 mA for single pulses ≤1 ms, but continuous operation must stay within DC limits derived from power dissipation. At IC = 100 mA and hFE = 420, IB ≈ 238 µA; practical design uses ≥5× overdrive (e.g., 1–5 mA) to ensure saturation, staying well below thermal limits on FR4 PCB.
Does BC847C-QVL support operation at –40 °C ambient?
Yes - its specified ambient temperature range is –65 °C to +150 °C, and all key parameters (hFE, VCE(sat), VBE) are characterized down to –55 °C in the datasheet. Real-world automotive cold-cranking operation at –40 °C is fully supported with no derating required.
How does the C-gain bin differ from A and B variants in circuit design?
The C-bin (hFE = 420–800) provides higher and tighter gain than A-bin (110–220) or B-bin (200–450), allowing smaller base resistors and more margin against beta degradation over temperature. This reduces sensitivity to manufacturing variation in bias networks for amplifiers and improves noise immunity in switching applications.
Can BC847C-QVL replace BC847B-Q in an existing design?
Yes, with verification - both share identical package, pinout, and voltage/current ratings, but BC847C-QVL's higher minimum hFE (420 vs. 200) may increase base current demand in some bias configurations. Confirm that the original design has sufficient base drive margin and that saturation remains guaranteed across temperature extremes.
