Infineon Technologies BCR 141S H6727

Overview

BCR 141S H6727 from Nexperia is a dual NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 22 kΩ), designed for switching, inverting, interfacing, and driver circuits in compact PCB layouts. 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 automotive-grade reliability.

For engineers reviewing the BCR 141S H6727 datasheet, BCR 141S H6727 pinout, BCR 141S H6727 application, or BCR 141S H6727 equivalent, key selection criteria include dual-transistor matching, built-in resistor tolerance (R1/R2 = 0.9–1.1), thermal resistance (R_thJS ≤ 140 K/W), RoHS-compliant SC74 (SOT-363) packaging, and guaranteed operation up to T_j = 150 °C.

Technical Context

This device integrates two electrically isolated NPN transistors with tightly matched characteristics in a single SC74 package-enabling space-efficient dual-channel logic-level switching without external bias networks. Its internal R1/R2 network simplifies base drive design while maintaining consistent turn-on/off thresholds across temperature (−40 °C to +125 °C).

The BCR 141S supports high-speed switching with f_T = 130 MHz and low C_cb = 3 pF, making it suitable for digital signal routing and level translation in automotive body control modules and industrial I/O interfaces where board area and thermal management are constrained.

Compared with BCR141S H6727, BCR142S offers higher input impedance for reduced MCU loading but sacrifices some switching speed; EMH3D100 reduces integration density and eliminates transistor matching-making it unsuitable for synchronized dual-signal paths like motor direction control or differential input buffering.

FAQ

Is BCR 141S H6727 pin-compatible with BCR 141U?

No - BCR 141S uses SC74 (SOT-363) with 6 pins (E1-B1-C2-E2-B2-C1), while BCR 141U uses SC74 (SOT-323) with 3 pins and a different internal configuration. Pin mapping differs entirely; direct substitution requires PCB redesign and validation of thermal performance (R_thJS = 105 K/W for U vs. 140 K/W for S).

What is the maximum continuous collector current per transistor at T_S = 85 °C?

At T_S = 85 °C, the derated P_tot remains 250 mW, and with V_CE(sat) ≤ 0.3 V, the absolute maximum continuous I_C per transistor is 83 mA (calculated as P_tot/V_CE(sat)). This aligns with the datasheet's 100 mA rating at T_S ≤ 115 °C.

Does the internal resistor network support reverse-bias operation (e.g., as a level shifter from 5 V to 3.3 V)?

No - the R1/R2 network is optimized for forward-active switching (NPN emitter-grounded configuration). Reverse-bias use violates the specified V_i(rev) = 10 V limit and risks damaging the base-emitter junction; dedicated level translators like TXB0108 are recommended for bidirectional voltage translation.

Can BCR 141S H6727 be used in linear amplification mode?

No - it is characterized and qualified exclusively for switching operation. The h_FE specification is given only at I_C = 5 mA and V_CE = 5 V (saturation region), and no small-signal parameters (e.g., r_π, g_m) or linearity data are provided. Linear use may cause thermal instability and parameter drift.
