Product details

Overview

BC860CWE6327HTSA1 from Infineon Technologies is a PNP silicon small-signal transistor designed for audio-frequency input stages and driver circuits. It delivers h_FE = 420–520 (at I_C = 2 mA), V_CEO = 45 V, V_CE(sat) ≤ 300 mV (at I_C = 10 mA / I_B = 0.5 mA), and f_T = 250 MHz - enabling low-noise amplification in compact analog signal paths.

For engineers reviewing the BC860CWE6327HTSA1 datasheet, BC860CWE6327HTSA1 pinout, BC860CWE6327HTSA1 application, or BC860CWE6327HTSA1 equivalent, key selection criteria include guaranteed h_FE group C performance, AEC-Q101 qualification for automotive use, SOT-323 package thermal resistance (R_thJS ≤ 90 K/W), and complementary pairing with BC849C/BC850C NPN types.

Technical Context

This PNP transistor operates in linear active and saturation regions with DC current gain specified across three h_FE groups (A/B/C) and validated at both I_C = 10 µA and I_C = 2 mA. Its low V_CE(sat) and high f_T support efficient switching and broadband amplification up to 100 MHz.

Noise figure is characterized at 1 kHz (F = 1–4 dB, I_C = 0.2 mA), and equivalent noise voltage is 0.11 µV (10–50 Hz, I_C = 200 mA), confirming suitability for low-level AF preamplifier stages where signal integrity is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - supports rail-to-rail operation in ±15 V analog systems without breakdown risk
h_FE (I_C = 2 mA)	420–520 - ensures stable biasing and predictable gain in emitter-follower or common-emitter configurations
V_CE(sat)	≤300 mV @ I_C/I_B = 10 mA/0.5 mA - minimizes power loss and self-heating in driver-stage saturation
f_T	250 MHz - enables reliable amplification of audio harmonics and RF-coupled control signals
C_cb	1.5 pF - limits Miller effect in high-gain amplifier designs, preserving bandwidth stability
Package	SOT-323 - surface-mount footprint compatible with automated assembly and thermal derating per R_thJS ≤ 90 K/W
AEC-Q101	Qualified - validated for automotive electronics under temperature cycling, humidity, and mechanical stress conditions

Pinout & Package

BC860CWE6327HTSA1 is housed in a RoHS-compliant SOT-323 (SC-70) plastic package with gull-wing leads, optimized for thermal dissipation (R_thJS ≤ 90 K/W) and board-space efficiency.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current source terminal for PNP operation	Connected to higher potential node; defines current direction and bias polarity in circuit topology
2 (Base)	Control input for minority-carrier injection	Requires negative-going drive relative to emitter to enable conduction; sensitive to ESD
3 (Collector)	Current sink terminal	Typically tied to load or supply rail; voltage swing limited by V_CEO = 45 V rating

Key Features

Feature	Design Value
Low-noise AF performance	F = 1–4 dB at 1 kHz, enabling clean signal amplification in microphone preamps and sensor interfaces
Guaranteed h_FE group C	h_FE ≥ 420 at I_C = 2 mA ensures consistent gain matching in matched-pair differential stages
Complementary NPN pairing	Designed as direct counterpart to BC849C/BC850C - simplifies push-pull and Class AB output stage design
High f_T / low C_cb ratio	250 MHz f_T with only 1.5 pF C_cb improves frequency response margin in feedback-stabilized amplifiers

Applications

Use Scenario: Signal conditioning for resistive temperature sensors (RTDs) in engine coolant or cabin climate modules.

IC Role / Device Role / Timing Role: Current-source bias generator and low-offset emitter follower for ratiometric bridge excitation.

Use Value: AEC-Q101 qualification ensures reliability across –40 °C to +125 °C ambient and vibration profiles per ISO 16750.

LED Driver Switch

Complementary Pair Amplifier

Use Value: Guaranteed h_FE group C matching (±10%) minimizes quiescent current drift over temperature.

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
BC857CWE6327HTSA1	V_CEO = 45 V (same), but h_FE group C min = 420 at I_C = 10 µA - lower bias-current sensitivity	Preferred in ultra-low-I_B bias networks (e.g., high-Z sensor buffers)	Select when base drive current must remain < 100 nA at room temperature
MMBT3906LT1G	V_CEO = 40 V, h_FE = 100–300 (no group C), R_thJS = 200 K/W - wider h_FE spread and poorer thermal performance	Acceptable for non-automotive consumer-grade logic-level switching	Choose only if AEC-Q101 compliance and tight h_FE matching are not required

Compared with BC857CWE6327HTSA1, BC860CWE6327HTSA1 offers superior h_FE consistency at moderate collector currents (2 mA), while MMBT3906LT1G lacks automotive qualification and exhibits higher thermal resistance - making BC860C the optimal choice for precision, thermally constrained, or safety-critical AF driver roles.

FAQ

Is BC860CWE6327HTSA1 pin-compatible with BC847C or BC857C?

No - BC860CWE6327HTSA1 uses SOT-323 packaging with emitter-base-collector pin order (1-2-3), whereas BC847C/BC857C in SOT-23 have collector-base-emitter (1-2-3). Physical pinout differs despite identical functional roles, requiring PCB layout revision for substitution.

What is the maximum continuous collector current at T_A = 85 °C?

At ambient temperature of 85 °C, the device's total power dissipation is derated to ~180 mW (per P_tot vs. T_S curve for SOT-323). With V_CE(sat) ≤ 300 mV, this supports I_C ≤ 600 mA in saturation - but safe continuous operation is limited to 100 mA per absolute maximum ratings to ensure long-term reliability.

Does BC860CWE6327HTSA1 support pulsed operation beyond its DC ratings?

Yes - pulse testing (t_p < 300 µs, duty cycle D < 2%) allows peak collector current up to 200 mA and instantaneous power up to 3× DC rating. The permissible pulse load curve confirms P_tot(max)/P_tot(DC) = 5 at t_p = 10 µs, enabling short-duration surge handling in protection circuits.

How does its noise performance compare to BC859C in audio applications?

BC860C exhibits lower equivalent noise voltage (0.11 µV vs. BC859C's 0.15 µV) and tighter h_FE grouping, resulting in improved gain stability and reduced 1/f noise contribution below 1 kHz. This makes BC860C preferable for high-fidelity microphone preamp stages where SNR > 95 dB is targeted.
