Infineon Technologies BCR 114T E6327

Overview

BCR 114T 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 ≤ 109 °C, and exhibits V_CE(sat) ≤ 0.3 V at I_C = 10 mA / I_B = 0.5 mA - used in microcontroller GPIO-level signal translation and LED driver stages.

For engineers reviewing the BCR 114T E6327 datasheet, BCR 114T E6327 pinout, BCR 114T E6327 application, or BCR 114T E6327 equivalent, key selection criteria include built-in resistor ratio (R1/R2 = 0.47), input on/off voltage thresholds (V_i(on) ≤ 1.4 V, V_i(off) ≥ 0.5 V), thermal resistance (R_thJS ≤ 165 K/W), and SC75 package compatibility with high-density PCB layouts.

Technical Context

This digital transistor integrates two precision bias resistors to eliminate external base drive components in saturated-switch configurations. Its fixed R1/R2 ratio ensures consistent turn-on behavior across temperature and process variation, enabling reliable logic-level interfacing without current-limiting calculations.

The device operates in common-emitter switching mode with guaranteed V_CE(sat) ≤ 0.3 V at I_C = 10 mA and h_FE ≥ 30 at I_C = 5 mA, supporting fast edge transitions up to f_T = 160 MHz while maintaining low standby leakage (I_EBO ≤ 520 µA).

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature for BCR 114T E6327?

The junction temperature (T_j) must not exceed 150 °C. The device is rated for total power dissipation of 250 mW at a solder-point temperature (T_S) ≤ 109 °C. Derating is required above this point per the P_tot vs. T_S curve in datasheet Figure 5, with R_thJS ≤ 165 K/W defining thermal path limits.

Can BCR 114T E6327 replace a standard NPN transistor like BC847?

No - BCR 114T E6327 is a digital transistor with integrated base resistors (R1 = 4.7 kΩ, R2 = 10 kΩ), whereas BC847 is a bare NPN requiring external biasing. Direct substitution would cause incorrect biasing and potential saturation failure. Use only where the internal resistor network matches the target circuit's drive requirements.

Is the SC75 package of BCR 114T E6327 compatible with standard SOT-23 footprints?

No - SC75 (SOT-416) has 0.65 mm pin pitch and 1.6 mm × 0.8 mm body, while SOT-23 measures 2.9 mm × 1.3 mm with 0.95 mm pitch. Layouts must use the exact SC75 land pattern per Infineon's package drawing; misalignment causes solder bridging or open connections during reflow.

What does the "E6327" suffix indicate in BCR 114T E6327?

E6327 denotes the tape-and-reel packaging format: 3,000 pieces per 180 mm diameter reel, with embossed carrier tape, cover tape, and moisture-sensitive level (MSL) 1 rating. It is not a revision code or performance variant - electrical and thermal specifications match the base BCR114T type.
