Product details
Overview
BC860BF E6327 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 (hFE = 250–475 at IC = 2 mA), low VCE(sat) (max 250 mV at IC = 10 mA / IB = 0.5 mA), and low noise (1 dB typical NF at 1 kHz), making it suitable for low-distortion preamplifier and level-shifting applications in automotive and industrial control modules.
For engineers reviewing the BC860BF E6327 datasheet, BC860BF E6327 pinout, BC860BF E6327 application, or BC860BF E6327 equivalent, key selection criteria include verified AEC-Q101 qualification, SOT-23 package thermal resistance (RthJS ≤ 240 K/W), complementary NPN pairing with BC847/BC848 series, and guaranteed hFE group B performance across temperature.
Technical Context
This PNP transistor operates in linear amplification and switching modes with VCEO = 45 V and VCBO = 50 V ratings, supporting bias-stable operation in emitter-follower and common-emitter configurations. Its fT of 250 MHz enables stable gain up to mid-VHF range, while Ccb = 1.5 pF and Ceb = 8 pF ensure minimal Miller effect in broadband AF designs.
Thermal design is constrained by Ptot = 330 mW at TS ≤ 71 °C and RthJS ≤ 240 K/W, requiring PCB copper area optimization for continuous 100 mA collector current handling. The device's 5 V VEBO rating limits base-emitter reverse bias in push-pull topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| hFE (IC = 2 mA) | 250–475 - Group B DC current gain ensures predictable bias point stability in amplifier feedback networks |
| VCE(sat) | 250 mV max - Enables low-loss switching and minimal voltage drop in active-load driver stages |
| fT | 250 MHz - Supports wideband AF amplification without phase margin degradation up to 100 kHz |
| Noise figure | 1 dB typ - Measured at IC = 0.2 mA, critical for low-noise microphone preamp front-ends |
| Ptot | 330 mW - Power dissipation limit at case temperature ≤ 71 °C, defining minimum copper pour area |
| RthJS | ≤ 240 K/W - Junction-to-soldering-point thermal resistance guides heatsinking strategy for reliability |
Pinout & Package
BC860BF E6327 is housed in a standard SOT-23 plastic surface-mount package with gull-wing leads, optimized for automated placement and reflow soldering. Pin assignment follows JEDEC TO-236AB outline with 1.9 mm × 1.3 mm footprint and 1.1 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Current-controlled input node | Accepts forward-biased base drive; requires current-limiting resistor to prevent IB > 5 mA peak |
| 2 (Emitter) | Common reference terminal | Connected to higher potential rail in PNP operation; defines VBE = −0.7 V nominal turn-on threshold |
| 3 (Collector) | Output current sink | Delivers amplified IC = hFE × IB; must be biased below emitter voltage by ≥45 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TC, and HAST |
| Low VCE(sat) | 250 mV max at IC/IB = 10/0.5 mA - reduces power loss and self-heating in driver IC interfaces |
| Group B hFE binning | 250–475 at IC = 2 mA - enables consistent gain matching without post-assembly trimming |
| RoHS-compliant | Pb-free SOT-23 package with matte tin lead finish - compatible with lead-free reflow profiles |
Applications
| Audio Preamp Stage | Level-Shifting Interface |
|---|---|
Use Scenario: Low-noise signal amplification in automotive cabin microphone circuits. IC Role / Device Role / Timing Role: PNP common-emitter amplifier providing 20 dB voltage gain with <1 dB THD+N.

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 |
|---|---|---|---|
| BC857BF E6327 | VCEO = 45 V, same hFE group B, but lower Ptot = 250 mW and RthJS = 90 K/W | Optimized for higher ambient temperature operation (TS ≤ 128 °C), less suited for sustained 100 mA loads | Select when thermal budget is constrained and peak current <50 mA |
| MMBT3906LT1G | VCEO = 40 V, hFE = 100–300 (no group binning), fT = 250 MHz, RoHS-compliant SOT-23 | Broader hFE spread increases need for circuit tolerance design; lacks AEC-Q101 validation | Choose for cost-sensitive consumer applications where automotive qualification is not required |
Compared with BC857BF E6327 and MMBT3906LT1G, BC860BF E6327 provides superior thermal robustness (330 mW @ 71 °C) and guaranteed hFE consistency, making it preferred for automotive-grade analog signal chains where long-term bias stability is critical.

FAQ
Is BC860BF E6327 pin-compatible with BC857BF E6327?
Yes - both use identical SOT-23 package with Base-Emitter-Collector pinout (1-2-3). However, BC860BF has higher Ptot (330 mW vs. 250 mW) and different thermal resistance (240 K/W vs. 90 K/W), so PCB thermal design must be revalidated when substituting.
What is the maximum continuous collector current for BC860BF E6327?
The absolute maximum continuous collector current is 100 mA, specified at TS ≤ 71 °C. At higher case temperatures, derating applies: e.g., 75 mA at TS = 100 °C per the Ptot-vs-TS curve in the datasheet.
Does BC860BF E6327 support pulsed operation beyond its DC ratings?
Yes - pulse operation up to 200 mA peak is allowed with duty cycle ≤5% and pulse width ≤300 µs, as defined by the permissible pulse load curve. Thermal transient response must be verified using RthJS = 240 K/W and junction temperature limits.
Can BC860BF E6327 replace BC856B in existing designs?
No - BC856B has VCEO = 65 V and is intended for higher-voltage applications. BC860BF's 45 V rating makes it unsuitable for circuits operating above 45 V collector-emitter, even if pinout and hFE appear similar.
