Product details
Overview
BC847-Q 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) spanning 110–800 at VCE = 5 V, IC = 2 mA. It serves as a low-power switching and amplification device in automotive body control modules, sensor interface stages, and LED driver bias circuits.
For engineers reviewing the BC847-Q datasheet, BC847-Q pinout, BC847-Q application, or BC847-Q equivalent, this page delivers verified electrical parameters, automotive qualification status, thermal resistance (500 K/W), saturation voltage (200–400 mV at IC = 100 mA), and exact pin mapping - all validated against Nexperia's Rev. 2 (24 June 2021) product data sheet.
Technical Context
This discrete NPN bipolar junction transistor operates in active, saturation, and cutoff regions with guaranteed breakdown voltages: VCBO = 50 V, VCEO = 45 V, and VEBO = 6 V. Its hFE spread accommodates design flexibility across gain-sensitive analog and digital functions.
Thermal performance is defined for FR4 PCB mounting (single-sided copper, tin-plated), with Rth(j-a) = 500 K/W and Tj(max) = 150 °C. Transient thermal impedance curves confirm pulse handling up to 200 mA peak collector current (tp ≤ 1 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit in switching applications. |
| IC | 100 mA continuous - Absolute maximum DC collector current; sets load-driving capacity in signal-level logic interfaces. |
| hFE | 110–800 @ VCE = 5 V, IC = 2 mA - Gain range enables selection of optimal bias stability for amplifier gain staging or switch saturation control. |
| VCE(sat) | 200–400 mV @ IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes power loss and heating in high-duty-cycle switching. |
| Ptot | 250 mW @ Tamb ≤ 25 °C - Total power dissipation limit on standard FR4 PCB; constrains thermal design margin in compact layouts. |
| Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance under specified PCB conditions; used to calculate temperature rise under load. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; dimensions per Fig. 14: 2.9 mm × 1.3 mm × 0.95 mm (L × W × H), standard footprint compatible with reflow and wave soldering per Figures 15–16.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires ~0.7 V forward bias and sufficient IB to drive IC into saturation or linear region. |
| 2 | Emitter (E) | Common reference terminal for NPN configuration; connected to ground or low-side return path in most switching topologies. |
| 3 | Collector (C) | Output current sink node; handles up to 100 mA DC load current with 45 V standoff capability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive applications including engine control units, lighting modules, and infotainment power management. |
| Three hFE variants (A/B/C) | Enables precise gain matching: BC847A-Q (110–220), BC847B-Q (200–450), BC847C-Q (420–800) - reduces calibration overhead in production. |
| Low VCE(sat) | 200–400 mV at full 100 mA load ensures <100 mW conduction loss, critical for thermally constrained PCBs in automotive ECUs. |
| Robust thermal rating | Tj(max) = 150 °C and Tstg = –65 to +150 °C support operation in under-hood environments and industrial ambient extremes. |
Applications
| Automotive Interior Lighting Control | Industrial Sensor Signal Conditioning |
|---|---|

Use Scenario: Driving 20 mA LED strings in door handle illumination and dashboard backlighting within vehicle cabin modules. IC Role / Device Role / Timing Role: NPN switch configured in common-emitter mode, controlled by microcontroller GPIO with base resistor network. Use Value: 45 V VCEO headroom accommodates 12 V automotive supply transients; 100 mA IC supports parallel LED strings without derating. |
Use Scenario: Amplifying low-level analog outputs (e.g., 0–100 mV) from pressure or temperature sensors before ADC sampling. IC Role / Device Role / Timing Role: Small-signal NPN amplifier in common-emitter configuration with emitter degeneration for linearity and gain stability. Use Value: hFE range up to 800 enables high-voltage gain with minimal external components; low noise figure (2–10 dB) preserves SNR in precision sensing. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Biasing |
|
Use Scenario: Enabling/disabling auxiliary power rails (e.g., 3.3 V LDO enable inputs) during startup/shutdown sequencing in washing machines and HVAC controllers. IC Role / Device Role / Timing Role: Digital switch controlling enable pins of downstream regulators via saturated on/off operation. Use Value: Fast turn-on/turn-off characteristics (supported by fT ≥ 100 MHz) ensure clean power-up timing; AEC-Q101 reliability extends to white-goods industrial use cases. |
Use Scenario: Providing stable bias current to op-amp input stages and photodiode transimpedance amplifiers in portable ultrasound and ECG front-ends. IC Role / Device Role / Timing Role: Precision current source built around BC847-Q in constant-current diode configuration with matched base-emitter voltage tracking. Use Value: Tight VBE specification (580–700 mV @ IC = 2 mA) and low ICBO (<15 nA) minimize drift and leakage-induced offset errors. |
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-Q | Higher hFE (200–450 vs. 110–800); tighter mid-range gain distribution. | Better suited for analog amplification where predictable mid-gain is required; less ideal for wide-tolerance switching. | Select when consistent β > 200 is needed for stable bias networks without trimming. |
| MMBT3904LT1G | Same SOT23 package but lower VCEO (40 V), higher VCE(sat) (300 mV min), and no AEC-Q101 qualification. | Limited to non-automotive consumer/industrial use; unsuitable for 12 V automotive transient environments. | Choose only for cost-sensitive non-automotive designs where 40 V rating suffices and qualification is not mandated. |
Compared with BC847B-Q, the BC847-Q offers broader hFE coverage for flexible design reuse, while MMBT3904LT1G lacks automotive qualification and has reduced voltage margin - making BC847-Q the preferred choice for safety-critical or high-reliability deployments.

FAQ
What is the maximum allowable junction temperature for BC847-Q?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in Table 6 of the Nexperia datasheet. This rating applies under continuous DC operation with proper PCB thermal management (FR4, single-sided copper, tin-plated). Exceeding this value risks permanent parametric shift or failure.
Does BC847-Q support pulsed operation beyond its DC current rating?
Yes - BC847-Q supports peak collector current (ICM) of 200 mA for single pulses ≤ 1 ms, as specified in Table 6. Pulse operation must respect duty cycle limits shown in Figure 1 to avoid thermal runaway; transient thermal impedance data confirms safe operation under these conditions.
How does the BC847-Q differ from the standard BC847 (non-Q) series?
The "-Q" suffix denotes AEC-Q101 qualification and automotive-grade screening, including enhanced reliability testing (HTOL, temperature cycling, bond wire pull tests). Electrically identical to non-Q variants, but with documented process controls, lot traceability, and failure rate reporting required for automotive Tier 1 suppliers.
Can BC847-Q be used in linear amplifier configurations?
Yes - BC847-Q is characterized for linear operation with specified hFE, VBE, and noise figure (2–10 dB at 1 kHz). Its fT ≥ 100 MHz and low Cc (1.5 pF) support audio and low-MHz signal amplification, provided VCE remains within recommended operating range and thermal limits are observed.
