Infineon Technologies BCR 114L3 E6327

Overview

BCR 114L3 E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = 4.7 kΩ, R2 = 10 kΩ), designed for low-power switching and interface applications. It supports 50 V V_CEO, 100 mA I_C, 250 mW P_tot at T_S ≤ 135 °C, and delivers V_CE(sat) ≤ 0.3 V at I_C = 10 mA / I_B = 0.5 mA - used in logic-level signal translation and LED driver stages.

For engineers reviewing the BCR 114L3 E6327 datasheet, BCR 114L3 E6327 pinout, BCR 114L3 E6327 application, or BCR 114L3 E6327 equivalent, key selection criteria include built-in resistor ratio (R1/R2 = 0.47), guaranteed h_FE ≥ 30 at 5 mA, thermal resistance R_thJS ≤ 60 K/W, and SC75 package compatibility with high-density PCB layouts.

Technical Context

This digital transistor integrates two precision on-chip resistors to enable single-pin base drive, eliminating external bias components in saturated-switch configurations. Its R1/R2 ratio of 0.47 ensures stable turn-on behavior across temperature, while f_T = 160 MHz supports fast edge transitions in digital interface circuits.

The device operates in common-emitter configuration with guaranteed V_i(on) ≤ 1.4 V and V_i(off) ≥ 0.5 V, enabling direct interfacing with 3.3 V and 5 V logic families. Junction temperature rating of 150 °C and R_thJS ≤ 60 K/W allow reliable operation in thermally constrained embedded modules.

FAQ

What is the maximum continuous collector current for BCR 114L3 E6327?

The absolute maximum continuous collector current is 100 mA, specified under conditions where case temperature does not exceed 135 °C and total power dissipation remains ≤ 250 mW. Derating applies above 135 °C per the P_tot vs. T_S curve in the datasheet.

Can BCR 114L3 E6327 replace a standard NPN transistor like BC847 in switching circuits?

Yes, but only when the circuit relies on externally biased base drive. BCR 114L3 E6327 integrates R1 and R2, so it replaces both the transistor and its two bias resistors - direct substitution requires removing those external components and verifying V_i(on)/V_i(off) thresholds match the driving source.

Is the SC75 package of BCR 114L3 E6327 compatible with standard SOT-23 pick-and-place equipment?

Yes - SC75 (SOT-416) has identical pad pitch (0.65 mm) and footprint dimensions (1.6 mm × 0.8 mm) to SOT-23, and is supported by most modern placement machines using standard SOT-23 nozzle tooling and vision alignment profiles.

Does BCR 114L3 E6327 support PWM-driven loads such as dimmable LEDs?

Yes - with f_T = 160 MHz and V_CE(sat) ≤ 0.3 V, it supports PWM frequencies up to 10–15 MHz. For typical LED dimming (1–10 kHz), switching losses are negligible, and thermal performance (R_thJS ≤ 60 K/W) ensures stable operation even at 100 % duty cycle.
