Product details

Overview

BC847C/SNVL from Nexperia is an NPN general-purpose bipolar junction transistor (BJT) in SOT23 (TO-236AB) package, rated for 45 V V_CEO, 100 mA I_C, and DC current gain (h_FE) of 420–800 at V_CE = 5 V and I_C = 2 mA. It serves as a low-voltage switching and small-signal amplification device in consumer power management, LED driver bias networks, and sensor interface stages.

For engineers reviewing the BC847C/SNVL datasheet, BC847C/SNVL pinout, BC847C/SNVL application, or BC847C/SNVL equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, real-world use cases in discrete analog signal chains, and confirmed alternative transistors with documented h_FE and V_CE(sat) differences.

Technical Context

This transistor operates in active and saturation regions with defined absolute maximum ratings: 45 V collector-emitter voltage, 100 mA continuous collector current, and 250 mW total power dissipation on FR4 PCB. Its thermal resistance (R_th(j-a)) is 500 K/W under standard mounting conditions.

The BC847C/SNVL exhibits a typical transition frequency (f_T) of 100 MHz at V_CE = 5 V and I_C = 10 mA, with base-emitter voltage (V_BE) ranging from 580–700 mV under same conditions. Saturation performance is characterized at I_C/I_B = 20, delivering V_CE(sat) ≤ 400 mV at I_C = 100 mA and I_B = 5 mA.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum safe collector-emitter voltage before breakdown in open-base configuration
I_C	100 mA - Continuous collector current rating defining usable load drive capability
h_FE	420–800 - DC current gain range at V_CE = 5 V, I_C = 2 mA, enabling predictable base drive sizing
V_CE(sat)	≤400 mV - Collector-emitter saturation voltage at I_C = 100 mA, I_B = 5 mA, ensuring low conduction loss in switch mode
P_tot	250 mW - Total power dissipation limit on standard FR4 PCB, constraining thermal design margin
f_T	100 MHz - Transition frequency indicating usable bandwidth for small-signal amplification up to ~10 MHz
R_th(j-a)	500 K/W - Junction-to-ambient thermal resistance under specified PCB layout, guiding heatsinking decisions

Pinout & Package

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires 5–10% of target I_C as I_B to ensure saturation
2	Emitter (E)	Common reference terminal; connected to ground or low-side return path in most switch configurations
3	Collector (C)	Output current sink node; handles full load current when saturated, routed to V_CC via load

Key Features

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/SNVL	h_FE = 200–450 (lower mid-range gain); identical V_CEO, I_C, and package	Less suitable for low-base-drive designs; preferred where tighter h_FE tolerance reduces variation in analog gain	Select when circuit gain stability outweighs need for high sensitivity to base current
MMBT3904LT1G	h_FE = 100–300 (narrower range); V_CEO = 40 V; V_CE(sat) = 300 mV @ I_C = 10 mA (not rated at 100 mA)	Lower saturation voltage at light loads but degrades above 50 mA; unsuitable for 100 mA switching	Choose only for ≤50 mA loads requiring minimal V_CE(sat); avoid for full-rated current operation

Compared with BC847B/SNVL and MMBT3904LT1G, BC847C/SNVL delivers highest guaranteed h_FE for minimal base drive, maintains full 100 mA capability with low V_CE(sat), and supports wider operating voltage margins-making it optimal for cost-sensitive, high-yield discrete switching where gain consistency is critical.

FAQ

What is the maximum continuous collector current for BC847C/SNVL?

The BC847C/SNVL is rated for 100 mA continuous collector current (I_C) at T_amb ≤ 25 °C on a standard FR4 PCB. At elevated ambient temperatures or reduced copper area, derating applies per the thermal resistance (500 K/W) and maximum junction temperature (150 °C) limits.

Does BC847C/SNVL support 5 V logic-level switching?

Yes. With V_CE(sat) ≤ 400 mV at I_C = 100 mA and I_B = 5 mA, BC847C/SNVL fully saturates using standard 5 V TTL/CMOS logic outputs. Base resistors of 1 kΩ–4.7 kΩ are typical for direct GPIO drive in low-side switch configurations.

How does BC847C/SNVL differ from BC847A/SNVL in practical design?

BC847C/SNVL has h_FE = 420–800 versus BC847A/SNVL's 110–220. This allows BC847C to operate with ~4× less base current for the same collector current, reducing MCU pin loading and improving noise immunity in high-impedance base drive networks.

Is BC847C/SNVL suitable for automotive applications?

No. Per Nexperia's revision history (Rev. 13, July 2022), the BC847x series is explicitly marked non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade qualification; use BC847C-Q/SNVL or equivalent automotive-grade variants for vehicle systems.
