Product details

Overview

BC848CWH6327XTSA1 from Infineon Technologies is an NPN silicon small-signal transistor in SOT323 (SC-70) package, rated for V_CEO = 30 V, I_C = 100 mA, and h_FE = 420–800 (at I_C = 2 mA), with low V_CE(sat) ≤ 250 mV (I_C = 10 mA, I_B = 0.5 mA). It serves in AF input stages and driver circuits of automotive and industrial signal conditioning modules.

For engineers reviewing the BC848CWH6327XTSA1 datasheet, BC848CWH6327XTSA1 pinout, BC848CWH6327XTSA1 application, or BC848CWH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, low-noise performance (F ≤ 4 dB at 1 kHz), high f_T = 250 MHz, and RoHS-compliant Pb-free construction in SOT323.

Technical Context

This transistor operates as a general-purpose NPN amplifier/switch with complementary PNP pairing (BC858–BC860 series). Its design emphasizes low V_CE(sat) and high h_FE stability across I_C = 10 µA to 100 mA, enabling efficient biasing in linear and switching modes.

Thermal performance is defined by R_thJS ≤ 105 K/W (SOT323 variant), supporting operation up to T_j = 150 °C. Noise figure is specified at 1.2–4 dB (IC = 200 µA, f = 1 kHz), making it suitable for low-level analog front-end amplification where signal integrity is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	30 V - Maximum collector-emitter voltage before breakdown under open-base conditions; defines safe operating range in low-voltage switching and amplification.
h_FE (I_C = 2 mA)	420–800 - High DC current gain enables low-base-drive designs, reducing loading on preceding stages in multi-stage amplifiers.
V_CE(sat)	≤ 250 mV @ I_C = 10 mA, I_B = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in digital switching applications.
f_T	250 MHz - Transition frequency supports stable amplification up to mid-VHF band, suitable for RF predriver and broadband audio stages.
C_cb	0.95 pF @ V_CB = 10 V - Low collector-base capacitance reduces Miller effect, improving high-frequency gain stability and bandwidth.
Noise Figure	1.2–4 dB @ I_C = 200 µA, f = 1 kHz - Enables use in low-noise preamplifier inputs where SNR preservation is essential.

Pinout & Package

Package: SOT323 (SC-70), surface-mount, 3-pin plastic case with standard lead finish per JEDEC MO-203AB. Thermal resistance R_thJS ≤ 105 K/W enables reliable operation at ambient temperatures up to +85 °C with appropriate PCB copper area.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	E	Current sink node; connects to ground or lower-potential rail; layout must minimize inductance for high-speed switching.
2 (Base)	B	Control terminal; requires current-limited drive (typically via 10–100 kΩ resistor) to avoid overdrive and thermal runaway.
3 (Collector)	C	Current source node; connects to load or next stage; trace width must support 100 mA continuous current without excessive heating.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive electronics per stress test requirements including HTOL, temperature cycling, and ESD; supports under-hood and infotainment applications.
Low V_CE(sat)	250 mV max ensures <1% voltage drop across transistor in saturated switch mode, preserving headroom in 3.3 V and 5 V logic-compatible interfaces.
High h_FE group C	420–800 gain range allows single-transistor amplification of microamp-level sensor signals without cascaded stages.
RoHS-compliant Pb-free	Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C) and halogen-free PCB assembly processes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN small-signal transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC848CW,115 (Nexperia)	Same SOT323 package, identical V_CEO/I_C/h_FE specs, but not AEC-Q101 qualified; R_thJS = 110 K/W (slightly higher thermal resistance).	Lacks automotive qualification; suitable for commercial-grade consumer and industrial control, not safety-critical automotive systems.	Select when AEC-Q101 is not required and cost optimization is prioritized over extended reliability validation.
MMBT3904LT1G (ON Semiconductor)	V_CEO = 40 V, h_FE = 100–300 (lower gain spread), f_T = 300 MHz, SOT23 package (larger footprint, lower thermal resistance R_thJS ≈ 240 K/W).	Higher voltage rating suits 12 V/24 V systems; wider package eases hand-soldering but increases board area vs. SOT323.	Choose for non-automotive applications needing higher V_CEO margin or where SOT23 placement compatibility is required.

Compared with BC848CWH6327XTSA1, BC848CW,115 offers identical electrical performance without automotive qualification, while MMBT3904LT1G trades gain consistency and package size for higher voltage tolerance and broader industry adoption-making each suitable for distinct reliability, thermal, and system-voltage contexts.

FAQ

Is BC848CWH6327XTSA1 pin-compatible with BC847C variants?

No-BC848CWH6327XTSA1 uses SOT323 (SC-70) packaging, while BC847C variants are offered in SOT23, TSFP-3, and TSLP-3-1 packages with different pin-to-package mappings. Pin numbering (E-B-C) is consistent, but mechanical fit and thermal performance differ significantly due to package geometry and thermal pad structure.

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is 200 mA (per datasheet limit), but for continuous DC operation, I_B must be limited to ensure I_C ≤ 100 mA and junction temperature remains ≤150 °C. At h_FE = 420, I_B ≤ 240 µA sustains I_C = 100 mA; practical designs use 1–5 mA with appropriate current-limiting resistors.

Does this part support pulsed operation beyond its DC ratings?

Yes-pulse operation up to I_C = 200 mA is permitted for t_p ≤ 10 ms (duty cycle ≤ 2%), as confirmed by the permissible pulse load curve (EHP00362). Thermal derating must follow the P_tot vs. T_S curves for SOT323, with peak junction temperature still capped at 150 °C.

How does its noise performance compare to BC849C and BC850C?

BC848CWH6327XTSA1 has F = 1.2–4 dB (1 kHz), matching BC849C but exceeding BC850C's 1.2 dB typical only below 50 Hz. At 10–50 Hz, BC850C achieves lower V_n = 0.135 µV, while BC848C maintains superior f_T and h_FE consistency-making BC848C preferred for general-purpose audio and sensor amplification above 100 Hz.
