Product details

Overview

BC860C,235 from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT23 package, rated for −45 V V_CEO, −100 mA I_C, and featuring h_FE of 420–800 at −2 mA/−5 V. It serves as an amplifying or switching device in low-voltage, low-noise analog signal paths-particularly in audio input stages and bias networks where stable DC gain and low leakage are critical.

For engineers reviewing the BC860C,235 datasheet, BC860C,235 pinout, BC860C,235 application, or BC860C,235 equivalent, this page delivers verified electrical parameters, thermal behavior on FR4 PCB, SOT23 terminal mapping, real-world use cases in audio and sensing circuits, and validated alternatives with documented gain and voltage differences.

Technical Context

This PNP BJT operates in active or saturation mode with base-emitter forward bias and collector-base reverse bias. Its DC current gain (h_FE) is specified at −2 mA I_C/−5 V V_CE, with typical values ranging 420–800 for the 'C' grade, and V_BEsat remains ≤ −850 mV at −100 mA I_C/−5 mA I_B.

Thermal resistance R_th(j-a) is 500 K/W when mounted on FR4, limiting continuous power dissipation to 250 mW at T_amb ≤ 25 °C. Leakage currents-including ICBO ≤ −15 nA at −30 V V_CB and IEBO ≤ −100 nA at −5 V V_EB-support stable operation in high-impedance biasing and low-current amplification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V: Maximum safe collector-emitter voltage before breakdown in open-base configuration.
I_C (DC)	−100 mA: Continuous collector current limit; defines usable linear/saturation range in switching or amplification.
h_FE	420–800 @ −2 mA/−5 V: High DC gain enables low-base-drive designs in preamplifier and current mirror applications.
V_CEsat	−75 to −300 mV @ −10 mA/−0.5 mA: Low saturation voltage minimizes power loss and voltage drop in switch-mode operation.
R_th(j-a)	500 K/W: Thermal resistance on FR4 board; determines junction temperature rise under 250 mW load at ambient.
C_c	4.5 pF @ −10 V V_CB: Collector junction capacitance affects high-frequency response and bandwidth in amplifier stages.
f_T	100 MHz: Transition frequency confirms suitability for audio-frequency and low-MHz signal amplification.

Pinout & Package

SOT23 plastic surface-mounted package (TO-236AB), 3-lead, dimensions per JEDEC outline: 2.9 × 1.3 × 1.0 mm (L × W × H), with gull-wing leads and standard thermal pad layout for FR4 mounting.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control electrode; forward-biased to inject holes into emitter region; requires current-limited drive for predictable h_FE-based operation.
2	Emiter	Current source terminal for PNP; connected to higher potential rail in common-emitter configurations; sets reference for V_EB biasing.
3	Collector	Output current sink; reverse-biased relative to base/emitter; handles up to −45 V and −100 mA with defined saturation characteristics.

Key Features

Feature	Design Value
High h_FE grade ('C')	420–800 gain range ensures consistent amplification across production lots without external trimming.
Low V_CEsat	≤ −300 mV at −10 mA enables efficient switching in battery-powered logic-level interfaces and LED drivers.
Low ICBO leakage	≤ −15 nA at −30 V supports stable DC operating points in high-gain, high-impedance amplifier inputs.
SOT23 footprint	Standardized 3-pin surface-mount package allows automated placement and reflow compatibility with mainstream PCB assembly lines.

Applications

Audio Input Stage

Current Mirror Reference

Use Scenario: First amplification stage in portable microphone preamplifiers or line-in buffers requiring minimal noise and stable DC bias.

IC Role / Device Role / Timing Role: PNP BJT configured in common-emitter topology to provide voltage gain with low input-referred noise (NF ≤ 4 dB).

Use Value: High h_FE reduces required base bias current, lowering thermal drift and improving SNR over temperature.

Use Scenario: Precision current replication circuit in sensor front-ends or ADC bias networks where matched gain and low offset matter.

IC Role / Device Role / Timing Role: Active component in two-transistor current mirror, leveraging matched h_FE and low V_BE variation (±50 mV) across devices.

Use Value: Tight h_FE tolerance (420–800) and low ICBO ensure <1% current error at room temperature and <3% over −40 to +125 °C.

Low-Voltage Switch

Emitter Follower Buffer

Use Scenario: Load control in 3.3 V or 5 V microcontroller I/O expansion, driving small relays or indicator LEDs.

IC Role / Device Role / Timing Role: Saturated PNP switch with base driven low by MCU GPIO; collector tied to load and supply rail.

Use Value: V_CEsat ≤ −300 mV at −10 mA limits power loss to <3 mW, enabling reliable operation without heatsinking.

Use Scenario: Impedance transformation between high-output-impedance DACs and low-input-impedance filters or cables.

IC Role / Device Role / Timing Role: Common-collector configuration providing unity voltage gain and high current drive capability.

Use Value: Low output impedance (<50 Ω) and f_T = 100 MHz support clean signal delivery up to 10 kHz with <0.1% THD.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC857C,235	V_CEO = −45 V (same); h_FE = 420–800 (identical); V_CEsat slightly higher (−100 to −400 mV).	Same SOT23 pinout and gain band; marginally higher saturation voltage may increase conduction loss in high-current switches.	Select when identical gain spec is required but BC860C,235 is out of stock; verify V_CEsat impact in final load conditions.
MMBT3906LT1G	V_CEO = −40 V (5 V lower); h_FE = 100–300 (lower grade); R_th(j-a) = 400 K/W (better thermal performance).	Lower gain and voltage rating restrict use to non-critical switching; better thermal resistance supports higher ambient operation.	Choose for cost-sensitive, non-audio applications where gain stability and voltage headroom are secondary to thermal margin.

Compared with BC857C,235, BC860C,235 offers identical gain and voltage specs but tighter V_CEsat control; versus MMBT3906LT1G, it delivers higher gain and voltage tolerance at the expense of slightly reduced thermal efficiency-making it preferable for precision analog and mid-voltage switching.

FAQ

Is BC860C,235 pin-compatible with BC849 or BC850?

No-BC849 and BC850 are NPN complements, not pin-compatible replacements. While all share the SOT23 package, their polarity reversal means base, emitter, and collector connections are inverted electrically. Direct substitution would reverse bias conditions and cause circuit failure unless topology is redesigned.

What is the maximum operating temperature for BC860C,235 in continuous operation?

The junction temperature must not exceed 150 °C. With R_th(j-a) = 500 K/W and P_tot = 250 mW at T_amb ≤ 25 °C, the device can sustain continuous operation up to approximately +115 °C ambient if derated linearly above 25 °C, assuming no additional heatsinking or airflow.

Does BC860C,235 support automotive-grade qualification?

No-BC860C,235 is not AEC-Q101 qualified. It is rated for industrial temperature range (−65 to +150 °C), but lacks automotive-specific stress testing, lot traceability, and failure rate reporting required for automotive applications.

How does the 'C' suffix differ from 'B' in BC860 variants?

The 'C' suffix denotes higher DC current gain: BC860C has h_FE = 420–800 at −2 mA/−5 V, while BC860B is 220–475. Both share identical voltage ratings (V_CEO = −45 V), saturation voltages, and thermal specs-only gain binning differs.
