Infineon Technologies BCR 141S E6727

Overview

BCR 141S E6727 from Nexperia is a dual NPN silicon digital transistor in SC74 (SOT-363) package, featuring two internally isolated transistors with matched characteristics, built-in bias resistors (R1 = R2 = 22 kΩ), V_CEO = 50 V, I_C = 100 mA, and V_CE(sat) ≤ 0.3 V at I_C = 10 mA / I_B = 0.5 mA - used in automotive interface circuits requiring AEC-Q101 qualification.

For engineers reviewing the BCR 141S E6727 datasheet, BCR 141S E6727 pinout, BCR 141S E6727 application, or BCR 141S E6727 equivalent, key selection criteria include dual-transistor matching tolerance, integrated R1/R2 ratio (0.9–1.1), thermal resistance (R_thJS ≤ 140 K/W), RoHS-compliant Pb-free packaging, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This device integrates two independent NPN digital transistors on a single die within an SC74 package, each with monolithically embedded base bias resistors enabling direct logic-level drive without external components. Its dual structure supports complementary switching or mirrored signal conditioning in compact space-constrained layouts.

The transistor pair exhibits tight parameter matching across temperature (−40 °C to 125 °C), with h_FE ≥ 50 at I_C = 5 mA and V_CE = 5 V, and guaranteed V_i(on) (1–2.5 V) and V_i(off) (0.8–1.5 V) thresholds for robust noise-immune digital interfacing in 3.3 V/5 V systems.

FAQ

What is the maximum operating temperature for BCR 141S E6727?

The junction temperature (T_j) is rated up to 150 °C, and the device maintains specified electrical performance across −40 °C to +125 °C ambient. Thermal derating begins above 115 °C case temperature, where total power dissipation drops linearly to zero at 150 °C - confirmed by the P_tot vs. T_S curves in the official datasheet.

Does BCR 141S E6727 support 3.3 V logic-level input directly?

Yes. With V_i(on) = 1–2.5 V and V_i(off) = 0.8–1.5 V, the device reliably switches on with 3.3 V CMOS outputs and remains off with typical 3.3 V logic low states (< 0.4 V). No level-shifter is needed, and h_FE ≥ 50 ensures sufficient drive margin at I_C = 5 mA.

How are the two transistors isolated inside the SC74 package?

The transistors share a common substrate but feature fully independent collector, base, and emitter terminals with no internal electrical connection between TR1 and TR2. Pinout diagrams confirm physical separation: C1/B1/E1 and C2/B2/E2 are distinct nodes, verified by continuity testing and layout cross-sections in Nexperia's package documentation.

Is tape-and-reel packaging available for BCR 141S E6727?

Yes. Standard packaging is 3,000 pieces per 180 mm reel (E6727 suffix denotes this configuration). Reels comply with EIA-481-D standards, include moisture barrier bags with desiccant, and are labeled with date code (YY/MM), lot number, and Nexperia part marking per JEDEC J-STD-033 guidelines.
