Infineon Technologies BCR 158F E6327

Overview

BCR 158F E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = 2.2 kΩ, R2 = 47 kΩ), designed for switching, inverting, interfacing, and driver circuits in automotive and industrial control systems. 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, and AEC-Q101 qualification.

For engineers reviewing the BCR 158F E6327 datasheet, BCR 158F E6327 pinout, BCR 158F E6327 application, or BCR 158F E6327 equivalent, key selection criteria include built-in resistor ratio (R1/R2 = 0.047), input on/off voltage thresholds (V_i(on) = 0.5–1.1 V, V_i(off) = 0.4–0.8 V), thermal resistance (R_thJS ≤ 240 K/W), and SOT23 package compatibility.

Technical Context

This digital transistor integrates two precision bias resistors to enable direct logic-level drive without external components. Its PNP topology supports high-side switching in low-voltage interface applications where base current sourcing is required.

The device operates across –65 °C to 150 °C junction temperature range, with guaranteed h_FE ≥ 70 at I_C = 5 mA/V_CE = 5 V and f_T = 200 MHz, supporting fast switching in signal conditioning and load control circuits.

FAQ

Is BCR 158F E6327 pin-compatible with BC807 or BC817?

No. BCR 158F E6327 is a digital transistor with integrated base resistors (R1/R2), while BC807/BC817 are conventional PNP transistors without internal biasing. Pin assignments differ: BCR158F has Base (Pin 1), Emitter (Pin 2), Collector (Pin 3); BC807 uses Emitter (Pin 1), Base (Pin 2), Collector (Pin 3) in SOT23. Direct substitution would cause incorrect biasing and functional failure.

What is the maximum allowable base drive voltage for BCR 158F E6327?

The absolute maximum input forward voltage (V_i(fwd)) is 20 V, and input reverse voltage (V_i(rev)) is 5 V. Exceeding V_i(rev) risks damaging the internal R2 resistor or emitter-base junction. For safe 3.3 V or 5 V logic drive, no series resistor is needed due to built-in R1, but clamping above 5 V requires external Zener protection.

Does BCR 158F E6327 support PWM switching at 25 kHz?

Yes. With f_T = 200 MHz and V_CE(sat) ≤ 0.3 V, the device supports clean switching at 25 kHz PWM frequencies. Rise/fall times are typically <10 ns under I_C = 10 mA conditions, ensuring minimal dead-time distortion and <1 % duty-cycle error in motor or LED dimming applications.

How does thermal derating work for BCR 158F E6327 in SOT23 package?

At T_S = 102 °C, total power dissipation is limited to 200 mW. Derating follows a linear curve: P_tot decreases by ~1.96 mW/°C above 102 °C, reaching zero at 205 °C. This reflects R_thJS ≤ 240 K/W; board layout (copper area, airflow) directly impacts real-world thermal performance and must be validated per AN077 guidelines.
