Product details

Overview

BC860CWE6327 from Infineon Technologies is a PNP silicon small-signal transistor designed for audio-frequency input stages and driver circuits. It delivers high DC current gain (h_FE = 420–520 at I_C = 2 mA), low V_CE(sat) (max 300 mV at I_C = 10 mA / I_B = 0.5 mA), and low noise (F = 1–4 dB, V_n = 0.11 µV in 10–50 Hz band), enabling precision amplification in battery-powered audio preamps.

For engineers reviewing the BC860CWE6327 datasheet, BC860CWE6327 pinout, BC860CWE6327 application, or BC860CWE6327 equivalent, key selection criteria include its AEC-Q101 qualification status (confirmed for BC860B/CW variants), SOT-323 package thermal resistance (R_thJS ≤ 250 K/W), and complementary NPN pairing with BC849C/BC850C for push-pull output stages.

Technical Context

This transistor operates as a linear active device in Class-A or Class-AB bias configurations, supporting DC-coupled gain stages and emitter-follower buffers. Its h_FE group C specification ensures consistent current amplification across production lots, while f_T = 250 MHz enables stable operation up to mid-audio frequencies without phase degradation.

The device features low base-emitter voltage (V_BE(ON) = 650–750 mV at I_C = 2 mA) and tight C_cb/C_eb capacitance (1.5 pF / 8 pF), minimizing Miller effect and preserving bandwidth in high-gain amplifier topologies with resistive collector loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Supports rail voltages up to ±22.5 V in dual-supply audio stages without breakdown
h_FE (I_C = 2 mA)	420–520 - Enables high-input-impedance, low-bias-current amplifiers with minimal base drive loss
V_CE(sat)	300 mV max - Reduces power dissipation in saturated-switching applications like LED drivers
f_T	250 MHz - Ensures flat gain response through 20 kHz with margin for stability compensation
C_cb	1.5 pF - Limits high-frequency feedback in common-emitter configurations
R_thJS	≤250 K/W - Allows 330 mW total dissipation at T_S ≤ 71 °C in SOT-323 footprint
Noise figure	1–4 dB - Meets low-noise requirements for microphone preamplifier first-stage design

Pinout & Package

BC860CWE6327 is housed in a RoHS-compliant SOT-323 (SC-70) plastic surface-mount package with gull-wing leads, optimized for automated placement and reflow soldering on dense PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to higher potential node in PNP configuration; sets bias current path
2 (Base)	Control input	Receives low-current drive signal; requires series resistor to limit I_B per h_FE target
3 (Collector)	Output current source	Delivers amplified current to load; typically tied to ground or negative rail in common-emitter stage

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive electronics use including infotainment front-end amplifiers
Low V_CE(sat)	Enables >95% efficiency in 3.3 V logic-level switching applications
Group C h_FE	Guarantees minimum gain of 420 at 2 mA, simplifying bias network design
Low 1/f noise	0.11 µV RMS in 10–50 Hz band supports high-fidelity sensor signal conditioning
Complementary NPN pairing	Matches BC849C/BC850C for matched-gain differential pairs in balanced audio circuits

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC857CW	V_CEO = 45 V, h_FE group B (220–480), R_thJS ≤ 250 K/W, same SOT-323 package	Lower gain spread reduces predictability in precision bias networks	Select when cost sensitivity outweighs need for tight h_FE matching
MMBT3906	V_CEO = 40 V, h_FE = 100–300 (I_C = 10 mA), C_cb = 4.5 pF, SOT-23 package	Higher capacitance limits bandwidth; non-AEC-Q101 rated	Acceptable for consumer-grade audio where automotive qualification is not required

Compared with BC857CW and MMBT3906, BC860CWE6327 provides superior gain consistency (group C), lower noise, and automotive qualification-making it optimal for safety-critical or high-fidelity analog signal paths where parameter stability is mandatory.

FAQ

Is BC860CWE6327 AEC-Q101 qualified?

Yes, BC860CWE6327 is explicitly qualified per AEC-Q101 Rev D for automotive applications. This is confirmed in the official Infineon datasheet revision dated 2011-09-19, which lists BC860B, BC860BW, and BC860CW as qualified variants. The "W" suffix denotes SOT-323 packaging and AEC-Q101 compliance.

What is the maximum operating junction temperature?

The absolute maximum junction temperature (T_j) for BC860CWE6327 is 150 °C, as specified in the "Maximum Ratings" table. Derating begins at T_S = 71 °C for the SOT-323 package, where total power dissipation drops linearly from 330 mW to zero at 150 °C ambient case temperature.

Can BC860CWE6327 replace BC857C in existing designs?

Yes, BC860CWE6327 can directly replace BC857C in most circuits due to identical pinout (SOT-323), same V_CEO/V_CBO ratings (45 V/50 V), and overlapping h_FE range. However, BC860C offers tighter h_FE grouping (420–520 vs. 420–800 for BC857C), improving bias stability in precision amplifiers.

What is the typical transition frequency at 10 mA collector current?

The datasheet specifies f_T = 250 MHz at I_C = 20 mA, V_CE = 5 V. At I_C = 10 mA, f_T remains ≥220 MHz based on the f_T vs. I_C curve (Figure EHP00378), ensuring usable gain beyond 100 kHz in linear amplifier applications.
