Infineon Technologies BCR 183L3 E6327

Overview

BCR 183L3 E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 10 kΩ), designed for low-power switching, level translation, and interface driver functions in compact logic circuits. It supports 50 V V_CEO, 100 mA I_C, 0.3 V V_CE(sat) at 10 mA/0.5 mA drive, and operates up to 150 °C junction temperature - commonly used in LED drivers and microcontroller GPIO buffer stages.

For engineers reviewing the BCR 183L3 E6327 datasheet, BCR 183L3 E6327 pinout, BCR 183L3 E6327 application, or BCR 183L3 E6327 equivalent, key selection criteria include its built-in resistor ratio (R1/R2 = 0.9–1.1), thermal resistance (R_thJS ≤ 60 K/W), SOT23-3 package footprint, and guaranteed V_i(on) (1–2.5 V) for TTL/CMOS-compatible input thresholds.

Technical Context

This device integrates two precision-matched resistors (R1, R2) directly into a single-chip PNP bipolar structure, eliminating external bias components and reducing PCB area. Its fixed R1/R2 ratio ensures stable turn-on behavior across temperature and process variation, while the 0.3 V saturation voltage enables efficient low-voltage switching down to 3.3 V logic rails.

The BCR 183L3 variant uses the TSLP-3-4 package (not SOT23), with thermal resistance optimized to ≤60 K/W - significantly lower than standard SOT23 versions - supporting higher continuous current capability at elevated board temperatures up to 135 °C soldering point.

FAQ

What is the maximum operating temperature for BCR 183L3 E6327?

The junction temperature limit is 150 °C, and the device is rated for continuous operation with a soldering point temperature up to 135 °C - verified by its R_thJS ≤ 60 K/W and derated power curves in the official datasheet. This allows use in sealed industrial enclosures without forced cooling.

Can BCR 183L3 E6327 replace a standard PNP transistor like BC807?

Yes, but only when the circuit relies on external base bias resistors. The BCR 183L3 E6327 integrates R1 and R2, so direct substitution requires removing those external resistors and verifying that the resulting V_i(on)/V_i(off) thresholds match system logic levels - especially critical at 3.3 V.

Is the TSLP-3-4 package compatible with standard SOT23 reflow profiles?

Yes - the TSLP-3-4 footprint is pin-compatible with SOT23-3 and uses identical pad dimensions and stencil recommendations. Its thinner profile (0.55 mm) does not require profile adjustments, though peak temperature must stay within JEDEC J-STD-020 limits for MSL1 handling.

Does BCR 183L3 E6327 support PWM switching above 10 kHz?

Yes - with f_T = 200 MHz and V_CE(sat) ≤ 0.3 V, it supports clean switching up to at least 500 kHz in low-duty-cycle applications. Rise/fall times are typically <10 ns under 10 mA load, making it suitable for LED dimming and motor control PWM at 20–100 kHz.
