Infineon Technologies BCR 179F E6327

Overview

BCR 179F E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistor (R1 = 10 kΩ), designed for switching, inverting, interface, and driver circuits. 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 = 120–630, and f_T = 150 MHz - used in compact logic-level signal translation and low-power load switching.

For engineers reviewing the BCR 179F E6327 datasheet, BCR 179F E6327 pinout, BCR 179F E6327 application, or BCR 179F E6327 equivalent, key selection criteria include its built-in R1 resistor enabling single-resistor base drive, SC75 package thermal performance (R_thJS ≤ 90 K/W), and guaranteed V_i(off) ≤ 1 V for reliable TTL/CMOS-compatible turn-off.

Technical Context

This digital transistor integrates a PNP bipolar junction transistor with a monolithic 10 kΩ base-emitter pull-up resistor (R1), eliminating external bias components in saturated-switch configurations. Its common-emitter switching behavior is characterized by tight V_CE(sat) control (≤0.3 V) and defined input thresholds: V_i(on) = 0.5–1.1 V and V_i(off) = 0.4–1 V at specified conditions.

The SC75 package supports surface-mount assembly with 1.6 mm × 0.8 mm footprint and 0.5 mm pitch, optimized for high-density PCB layouts. Thermal resistance to soldering point is ≤90 K/W, enabling stable operation up to T_J = 150 °C under pulsed or DC loads within derated P_tot = 250 mW limits.

FAQ

Is BCR 179F E6327 pin-compatible with standard SOT-23 transistors?

No - BCR 179F E6327 uses SC75 (SOT-416) package with 0.5 mm lead pitch and 1.6 mm × 0.8 mm footprint, differing from SOT-23's 0.95 mm pitch and 2.9 mm × 1.3 mm size. Pin 1–3 assignment (B–E–C) matches SOT-23 mechanical orientation but requires PCB land pattern revision for replacement.

What is the maximum allowable base current for reliable operation?

The datasheet specifies I_B = 0.5 mA for V_CE(sat) testing, and absolute maximum ratings do not define I_B limit separately. However, with R1 = 10 kΩ, applying >1.5 V to pin 1 yields I_B < 0.15 mA, well within safe operating area; exceeding 5 V input risks exceeding P_tot = 250 mW if V_CE is high.

Can BCR 179F E6327 be used in linear amplifier configurations?

No - it is optimized for digital switching, not analog amplification. The integrated R1 biases the device for saturation/cutoff operation, and h_FE variation (120–630) and lack of small-signal linearity data make it unsuitable for linear gain stages. Use discrete BJT or dedicated amplifier ICs instead.

Does this part support reflow soldering per J-STD-020?

Yes - the SC75 package is rated for standard lead-free reflow profiles. Peak temperature must not exceed 260 °C for ≤30 seconds, and moisture sensitivity level (MSL) is 1 (unlimited floor life at ≤30 °C/60% RH), per Infineon's packaging specification for this product family.
