Product details

Overview

BCR141E6327HTSA1 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 22 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, h_FE ≥ 50, and AEC-Q101 qualification.

For engineers reviewing the BCR141E6327HTSA1 datasheet, BCR141E6327HTSA1 pinout, BCR141E6327HTSA1 application, or BCR141E6327HTSA1 equivalent, key selection criteria include built-in resistor matching, thermal resistance (R_thJS ≤ 105 K/W), RoHS-compliant SC74 (SOT-363) packaging, and guaranteed performance across −40 °C to +125 °C junction temperature range.

Technical Context

This device integrates two matched NPN transistors in a single SC74 package, enabling compact dual-channel logic-level switching without external bias networks. Its internal R1/R2 ratio of 0.9–1.1 ensures consistent turn-on/off thresholds across temperature (−40 °C to +125 °C) and process variation.

The transistor operates in common-emitter configuration with defined input voltage thresholds: V_i(on) = 1–2.5 V (I_C = 2 mA, V_CE = 0.3 V) and V_i(off) = 0.8–1.5 V (I_C = 100 µA, V_CE = 5 V), supporting direct microcontroller GPIO interfacing without level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum allowable collector-emitter voltage before breakdown; supports 24 V industrial bus and 12 V automotive loads.
I_C	100 mA - Continuous collector current rating; sufficient for driving relays, LEDs, and small solenoids.
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.
h_FE	≥ 50 @ I_C = 5 mA, V_CE = 5 V - Ensures reliable current amplification with standard logic-level base drive.
R1 / R2	22 kΩ / 22 kΩ ±10% - Matched on-chip bias resistors eliminate discrete component count and layout sensitivity.
f_T	130 MHz typ. - Enables stable operation up to ~10 MHz square-wave switching with minimal propagation delay.
R_thJS	≤ 105 K/W - Thermal resistance from junction to soldering point; enables 250 mW dissipation at T_S ≤ 118 °C.

Pinout & Package

BCR141E6327HTSA1 uses the SC74 (SOT-363) surface-mount package: 6-pin, dual-transistor layout with pin 1 = E1, pin 2 = B1, pin 3 = C2, pin 4 = E2, pin 5 = B2, pin 6 = C1. The package is RoHS-compliant, qualified per AEC-Q101, and optimized for automated placement and reflow.

Pin/Terminal	Circuit Role	Design Meaning
1 (E1)	Emitter of Transistor 1	Common emitter node for first NPN; tied internally to R2; requires external connection to ground or reference.
2 (B1)	Base of Transistor 1	Input node for TR1; connected internally to R1 and R2 junction; accepts logic-level signals directly.
3 (C2)	Collector of Transistor 2	Output node for second NPN; open-collector capable; drives loads referenced to V_CC.
4 (E2)	Emitter of Transistor 2	Emitter node for TR2; electrically isolated from E1; used for independent biasing or differential configurations.
5 (B2)	Base of Transistor 2	Input node for TR2; identical internal bias structure as B1; supports dual independent switching channels.
6 (C1)	Collector of Transistor 1	Primary output node for TR1; rated for 50 V and 100 mA; compatible with 3.3 V/5 V MCU outputs.

Key Features

Feature	Design Value
Dual matched NPN transistors	Two electrically isolated, thermally coupled transistors in one SC74 package with <10% h_FE mismatch across temperature.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCR142E6327HTMA1	Same SC74 package and bias resistors, but h_FE min = 100 (vs. 50); higher gain improves noise margin in low-current sensing.	Preferred where base drive current is limited (e.g., ultra-low-power MCUs), but less tolerant of leakage-induced false triggering.	Select when higher DC gain is required and system noise immunity allows tighter V_i(off) margins.
NSVD2101PT3G	Single-channel SOT-23 device with R1 = 47 kΩ, R2 = open; no dual-transistor integration; lower thermal resistance (R_thJS ≤ 80 K/W).	Used where space permits discrete placement and only one switch is needed per footprint; lacks TR1/TR2 matching.	Choose for cost-sensitive single-channel designs requiring maximum thermal headroom, not dual-channel matching.

Compared with BCR141E6327HTSA1, BCR142E6327HTMA1 offers higher h_FE for improved drive efficiency but reduced noise immunity, while NSVD2101PT3G trades dual-channel integration for better thermal performance in single-switch roles.

FAQ

What is the maximum operating junction temperature for BCR141E6327HTSA1?

The absolute maximum junction temperature is 150 °C. Derating begins at T_S = 118 °C, where total power dissipation drops linearly from 250 mW to zero at 150 °C. This limit is validated under AEC-Q101 stress testing and applies across all operating conditions including pulsed loads with duty cycle D ≤ 0.5.

Can BCR141E6327HTSA1 be used in high-frequency switching applications?

Yes-it has a typical transition frequency f_T of 130 MHz and exhibits stable switching behavior up to 10 MHz square waves. However, its primary design focus is DC and low-frequency digital switching (≤1 MHz); for >20 MHz operation, dedicated RF transistors with lower C_cb (e.g., <2 pF) are recommended.

Is the internal resistor ratio R1/R2 tightly controlled?

Yes-the datasheet specifies R1/R2 = 0.9 to 1.1, meaning the ratio is held within ±10% across process, voltage, and temperature (−40 °C to +125 °C). This tight matching ensures consistent V_i(on) and V_i(off) thresholds between the two integrated transistors.

Does BCR141E6327HTSA1 support bidirectional signal routing?

No-it is a unidirectional NPN digital transistor with fixed emitter-base-collector polarity. The internal diode structure and bias network prevent reverse current flow; it cannot function as a bilateral switch or analog multiplexer. For bidirectional applications, discrete MOSFETs or analog switches must be used instead.
