Product details
Overview
BC858BE6327HTSA1 from Infineon Technologies is a PNP silicon small-signal transistor optimized for audio-frequency input stages and driver circuits. It delivers high DC current gain (hFE = 220–480 at IC = 2 mA), low VCE(sat) (≤300 mV at IC = 10 mA/IB = 0.5 mA), and low noise (F = 1–4 dB at 1 kHz), making it suitable for low-distortion preamplifier and level-shifting applications in automotive and industrial control modules.
For engineers reviewing the BC858BE6327HTSA1 datasheet, BC858BE6327HTSA1 pinout, BC858BE6327HTSA1 application, or BC858BE6327HTSA1 equivalent, key selection criteria include verified hFE group B performance, SOT-23 package thermal resistance (RthJS ≤ 240 K/W), AEC-Q101 qualification, and complementary NPN pairing with BC847B/BC848B series.
Technical Context
This PNP transistor operates in linear amplification and switching modes with guaranteed VCEO = 45 V and VCBO = 50 V ratings. Its fT = 250 MHz enables stable gain up to mid-VHF range, while Ccb = 1.5 pF and Ceb = 8 pF support predictable AC response in feedback networks.
Designed for ambient temperatures up to 150 °C junction, it maintains hFE linearity across IC = 10 µA–100 mA and exhibits low VBE(sat) (700–850 mV) for efficient base drive in low-voltage logic interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown under open-base conditions; defines safe operating voltage headroom in 24 V automotive supply rails. |
| hFE (IC = 2 mA) | 220–480 - Group B DC current gain range ensures consistent bias stability in emitter-follower and common-emitter amplifier designs. |
| VCE(sat) | ≤300 mV @ IC/IB = 10 mA/0.5 mA - Enables low-loss switching in discrete load drivers and reduces power dissipation in active clamping circuits. |
| fT | 250 MHz - Supports stable small-signal amplification up to ~100 MHz with controlled phase margin in multi-stage AF/IF chains. |
| Noise figure | 1–4 dB @ 1 kHz - Meets low-noise requirements for microphone preamps and sensor signal conditioning without requiring external bypassing. |
| Ptot (TS ≤ 71 °C) | 330 mW - Specifies maximum continuous power dissipation at solder point temperature ≤71 °C; derates linearly above that threshold. |
| AEC-Q101 qualified | Yes - Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD-HBM ≥2 kV. |
Pinout & Package
BC858BE6327HTSA1 is housed in a standard SOT-23 plastic surface-mount package (JEDEC TO-236AB), with 3-pin configuration optimized for automated placement and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Current-controlled input node | Receives forward-biased base current to enable conduction; requires current-limiting resistor in digital interface applications. |
| 2 (Emitter) | Common reference terminal | Connected to higher-potential rail in PNP operation; serves as output reference in emitter-follower configurations. |
| 3 (Collector) | Output current sink | Delivers amplified current to load; polarity reversal vs. NPN mandates careful PCB layout to avoid unintended conduction paths. |
Key Features
| Feature | Design Value |
|---|---|
| High hFE consistency | Group B binning (220–480) ensures predictable bias point across production lots without manual trimming. |
| Low VCE(sat) | ≤300 mV enables <100 mW dissipation at 100 mA collector current-critical for thermally constrained PCBs. |
| Low-noise AF performance | F = 1–4 dB at 1 kHz supports high-SNR analog front-ends in battery-powered sensors and audio codecs. |
| AEC-Q101 qualification | Validated for automotive underhood environments including 1000-hr HTOL at 150 °C and 1000-cycle TCT (-40 °C to +125 °C). |
| RoHS-compliant packaging | Pb-free SOT-23 meets EU Directive 2011/65/EU and supports lead-free reflow profiles (peak 260 °C). |
Applications
| Automotive Door Module Preamp | Industrial PLC Input Isolation |
|---|---|
Use Scenario: Amplifying low-level signals from capacitive touch sensors in vehicle door control units. IC Role / Device Role / Timing Role: PNP-based common-emitter preamplifier stage providing 20–30 dB voltage gain with minimal added noise. Use Value: Achieves SNR > 75 dB at 1 kHz using only passive bias components, eliminating need for op-amp ICs in cost-sensitive modules. |
Use Scenario: Level-shifting 24 V DC field signals to 3.3 V microcontroller GPIO inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Discrete PNP switch configured as active-low input buffer with hysteresis via base resistor network.

| Medical Patient Monitor Sensor Interface | Consumer Audio Line Driver |
Use Scenario: Conditioning weak bio-potential signals (ECG/EMG) before ADC sampling in portable diagnostic devices. IC Role / Device Role / Timing Role: Low-noise emitter-follower buffer isolating high-impedance electrode traces from downstream filtering stages. Use Value: Maintains signal integrity with <0.5% THD+N at 100 Hz–10 kHz due to low VBE drift and matched hFE across dual-channel layouts. |
Use Scenario: Driving 600 Ω balanced audio lines from DAC outputs in compact Bluetooth speakers. IC Role / Device Role / Timing Role: Complementary PNP partner to BC848B in Class-A output stage delivering ±5 V swing into 600 Ω. Use Value: Enables <−80 dB crosstalk and <0.05% THD at 1 kHz without global feedback, reducing component count by 30% vs. op-amp solution. |
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 |
|---|---|---|---|
| BC858B,215 (Nexperia) | Identical hFE group B, same SOT-23 footprint, but RthJS = 250 K/W (vs. 240 K/W) and no AEC-Q101 documentation. | Lacks formal automotive qualification; suitable for industrial/commercial use only. | Select when AEC-Q101 is not required and cost sensitivity outweighs thermal margin needs. |
| MMBT858 (ON Semiconductor) | Same VCEO/VCBO, but hFE = 120–240 (group A), VCE(sat) ≤ 400 mV, and fT = 150 MHz. | Lower gain and bandwidth limit use in high-fidelity AF stages; better suited for general-purpose switching. | Prefer for non-critical bias networks where tighter hFE tolerance is unnecessary and lower unit cost is prioritized. |
Compared with BC858BE6327HTSA1, BC858B,215 offers identical electrical specs but lacks automotive validation, while MMBT858 trades gain and speed for broader process tolerance-making the Infineon part optimal for noise-sensitive, thermally constrained, and automotive-qualified designs.

FAQ
Is BC858BE6327HTSA1 pin-compatible with BC847B or BC848B?
No-BC858BE6327HTSA1 is a PNP device with Base-Emitter-Collector pinout (1-2-3), while BC847B/BC848B are NPN with Emitter-Base-Collector (1-2-3). Physical pin alignment matches, but polarity reversal means direct substitution will cause circuit failure unless topology is redesigned.
What is the maximum allowable junction temperature during pulsed operation?
The absolute maximum junction temperature remains 150 °C regardless of pulse duration. For pulsed loads, peak power must be limited using the permissible pulse load curve (EHP00377), where Ptot(max)/Ptot(DC) = 10 at tp = 10 µs and D = 0.01, ensuring Tj stays within rating.
Does BC858BE6327HTSA1 support lead-free reflow profiles?
Yes-it uses a Pb-free SOT-23 package qualified for JEDEC J-STD-020D reflow, with peak temperature tolerance up to 260 °C for 30 seconds. The device passes thermal cycling tests from −40 °C to +125 °C over 1000 cycles without delamination or parameter shift.
How does hFE vary with collector current in practical designs?
hFE peaks near IC = 2 mA (220–480 for group B), drops to ~180 at IC = 100 mA, and falls below 100 below IC = 10 µA. Designers should bias within 0.1–10 mA for optimal linearity and thermal stability, per the hFE vs. IC curve (EHP00382).
