Product details
Overview
BC860BWE6327 from Infineon Technologies is a PNP silicon small-signal transistor designed for audio-frequency input stages and driver applications. It delivers DC current gain (hFE) of 220–480 at IC = 2 mA, VCE = 5 V; VCEO = 45 V; VCE(sat) ≤ 250 mV at IC = 10 mA, IB = 0.5 mA; and fT = 250 MHz - enabling low-noise amplification in compact analog signal paths.
For engineers reviewing the BC860BWE6327 datasheet, BC860BWE6327 pinout, BC860BWE6327 application, or BC860BWE6327 equivalent, key selection criteria include its AEC-Q101 qualification status (confirmed for BC860B variant), SOT-323 package thermal resistance (RthJS ≤ 105 K/W), and complementary pairing with BC847–BC850 NPN series in push-pull configurations.
Technical Context
This PNP transistor operates in linear active and saturation regions for analog amplification and switching. Its hFE grouping (B-grade) ensures consistent current amplification across production lots, while low VCE(sat) and VBE(sat) support efficient biasing in low-voltage driver circuits.
The device exhibits 1.5 pF collector-base capacitance and 8 pF emitter-base capacitance at specified test conditions, contributing to stable high-frequency response up to 250 MHz. Its noise figure is 1 dB typical at IC = 0.2 mA, making it suitable for low-level AF signal conditioning where SNR preservation is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - supports operation in 36 V rail systems with margin against transients |
| hFE (IC = 2 mA) | 220–480 - enables predictable bias point setting in discrete amplifier stages |
| VCE(sat) | ≤250 mV @ IC/IB = 10 mA/0.5 mA - minimizes power loss in saturated switch mode |
| fT | 250 MHz - sufficient for wideband AF and low-MHz digital signal buffering |
| Package | SOT-323 - surface-mount footprint compatible with automated assembly and thermal management via PCB copper pour |
| Thermal Resistance RthJS | ≤105 K/W - allows 250 mW dissipation at junction-to-solder-point interface under defined layout |
| Noise Figure | 1 dB typ. @ 1 kHz - preserves signal integrity in preamplifier inputs |
Pinout & Package
BC860BWE6327 is housed in a RoHS-compliant SOT-323 (SC-70) plastic package with gull-wing leads, optimized for high-density PCB layouts and reflow soldering. The package measures 2.13 mm × 1.3 mm × 0.9 mm and features a thermal pad-compatible land pattern per Infineon's recommended footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Reference node for current sourcing; connects to higher potential in PNP operation |
| 2 (Base) | Control terminal | Receives forward-biased current to regulate collector-emitter conduction |
| 3 (Collector) | Output terminal | Current sink path; typically connected to load or next stage input |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB) |
| Low VCE(sat) | 250 mV max at IC = 10 mA - reduces heat generation in driver stages |
| High hFE consistency | B-grade binning (220–480) - simplifies bias network design without trimming |
| Low-noise performance | F = 1 dB typ. @ 1 kHz - suitable for microphone preamps and sensor signal conditioning |
| Complementary NPN pairing | Matched with BC847B–BC850B series - enables balanced differential and push-pull topologies |

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 |
|---|---|---|---|
| BC857BW | VCEO = 45 V, hFE = 220–480 (B-grade), same SOT-323 package, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial designs only | Select when AEC-Q101 compliance is unnecessary and cost sensitivity is higher |
| MMBT3906 | VCEO = 40 V, hFE = 100–300, SOT-23 package, RthJS = 240 K/W, no AEC-Q101 qualification | Lower voltage rating and thermal performance; requires larger PCB area for thermal relief | Choose only if legacy SOT-23 footprint compatibility is mandatory and 40 V margin suffices |
Compared with BC857BW and MMBT3906, BC860BWE6327 offers superior automotive qualification, tighter hFE binning, and better thermal resistance - making it optimal for safety-critical or high-reliability AF driver implementations where long-term stability and transient immunity are essential.

FAQ
Is BC860BWE6327 pin-compatible with BC857BW?
Yes - both use identical SOT-323 packaging and share the same pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. No PCB redesign is needed when upgrading from BC857BW to BC860BWE6327 for AEC-Q101 compliance.
What is the maximum continuous collector current for BC860BWE6327?
The absolute maximum continuous collector current is 100 mA at TS ≤ 124 °C. Derating applies above this temperature; at 71 °C ambient, the device supports full 100 mA with proper PCB copper area per Infineon's thermal guidelines.
Does BC860BWE6327 support pulsed operation beyond its DC ratings?
Yes - peak collector current reaches 200 mA for pulses ≤10 ms (duty cycle ≤2%). Pulse capability is validated per JEDEC JESD78, with permissible pulse load curves provided in Infineon's application note AN077.
How does BC860BWE6327 differ from BC860C variants?
BC860BWE6327 uses B-grade hFE (220–480), whereas BC860C offers C-grade (420–800). Both share identical voltage ratings, package, and AEC-Q101 qualification - selection depends on required gain range and bias stability needs.
