Product details

Overview

BCR 142F E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = 22 kΩ, R2 = 47 kΩ), designed for switching, inverting, interface, and driver circuits in automotive and industrial control systems. It features V_CEO = 50 V, I_C = 100 mA, V_CE(sat) ≤ 0.3 V at I_C = 10 mA / I_B = 0.5 mA, and AEC-Q101 qualification.

For engineers reviewing the BCR 142F E6327 datasheet, BCR 142F E6327 pinout, BCR 142F E6327 application, or BCR 142F E6327 equivalent, this page delivers verified electrical characteristics, thermal performance curves, SOT23 package layout, and direct substitution guidance for automotive-grade digital switching designs.

Technical Context

This digital transistor integrates two on-chip resistors to enable single-pin base drive-eliminating external bias components in low-power switching nodes. Its R1/R2 ratio of 0.47 ensures stable saturation under varying temperature conditions (–40°C to 125°C) and supports reliable logic-level interfacing with microcontrollers and gate drivers.

The device operates in common-emitter configuration with h_FE ≥ 70 at I_C = 5 mA / V_CE = 5 V, f_T = 150 MHz, and C_cb = 3 pF, making it suitable for medium-speed digital signal routing where compact footprint and predictable turn-on/off behavior are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin.
I_C	100 mA - Continuous collector current rating; supports LED drivers, relay coils, and small-signal MOSFET gates.
V_CE(sat)	≤ 0.3 V @ I_C/I_B = 20 - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching.
R1 / R2	22 kΩ / 47 kΩ - Fixed internal bias network eliminates external resistor placement and reduces PCB area by ~2 mm² per instance.
f_T	150 MHz - Transition frequency confirms suitability for pulse widths down to ~2 ns; adequate for PWM up to 10 MHz.
AEC-Q101	Qualified - Meets stress-test requirements for automotive electronics, including temperature cycling, HTRB, and ESD.

Pinout & Package

SOT23-3 plastic surface-mount package with gull-wing leads; 1.3 mm body height, 2.9 mm × 1.3 mm footprint, and JEDEC MO-203-AB compliant outline.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Input node connected to internal R1–R2 divider midpoint	Accepts TTL/CMOS logic-level signals directly; no external pull-up/down required.
2 (Emitter)	Common emitter reference terminal	Connected to ground or low-side return path; defines current sink operation mode.
3 (Collector)	Switched output terminal	Drives load between V_CC and collector; supports active-low switching topology.

Key Features

Feature	Design Value
Integrated bias resistors	R1 = 22 kΩ ±30 %, R2 = 47 kΩ ±30 % - Reduces component count and improves assembly yield in high-volume automotive modules.
Low V_CE(sat)	≤ 0.3 V at I_C = 10 mA - Limits conduction loss to <3 mW, enabling thermally constrained layouts without forced air cooling.
High h_FE	≥ 70 at 5 mA - Ensures robust drive margin across temperature extremes (–40°C to +125°C junction).
Thermal resistance	R_thJS ≤ 240 K/W (SOT23) - Enables 200 mW dissipation at T_S ≤ 102°C; supports board-level thermal design without copper pour.

Equivalent & Alternatives

The following parts are listed as comparable options for similar digital transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC847B,215	No integrated resistors; requires external R_B and R_BE; h_FE = 200–450; V_CEO = 45 V	Higher gain but lacks built-in biasing; needs additional PCB space and tuning for stable switching	Prefer when fine-tuned base current control is needed or when operating near 45 V rail limits
NSV14201T1G	R1 = 22 kΩ, R2 = 47 kΩ; same pinout; RoHS-compliant; V_CEO = 50 V; I_C = 100 mA	Functionally identical but manufactured by ON Semiconductor; slightly higher V_CE(sat) (0.35 V max)	Drop-in replacement where second-source assurance is required; verify thermal derating at >100°C ambient

FAQ

What is the maximum allowable junction temperature for continuous operation?

The absolute maximum junction temperature (T_j) is 150 °C. Derating begins at T_S = 102 °C for the SOT23 package, where total power dissipation drops linearly from 200 mW to zero at 150 °C. Operation above 150 °C risks permanent parametric shift or bond-wire failure.

Can BCR 142F E6327 replace a standard NPN transistor like BC847 in existing designs?

Yes-but only if the circuit relies on fixed-base-current drive and does not require adjustable h_FE or variable saturation behavior. The integrated R1/R2 network fixes input impedance; removing external resistors is mandatory, and V_CE(sat) may differ by up to 50 mV versus discrete implementations.

Is the SOT23 package lead-free and RoHS-compliant?

Yes-BCR 142F E6327 uses Pb-free terminations and complies fully with EU RoHS Directive 2011/65/EU. The package material meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1, allowing unlimited floor life at ≤30 °C/60 % RH.

How does the R1/R2 ratio affect switching performance?

The R1/R2 ratio of 0.47 ensures sufficient base current to maintain saturation across temperature and process variation. At I_C = 10 mA, it delivers I_B ≈ 0.5 mA-providing ≥20× overdrive margin even at –40 °C, preventing unintended cutoff during cold cranking in automotive environments.
