Infineon Technologies BCR 192T E6327

Overview

BCR 192T E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = 22 kΩ, R2 = 47 kΩ), designed for switching, inverter, interface, and driver circuits in compact SOT-23 packages. It features dual galvanically isolated transistors in one package, V_CEO = 50 V, I_C = 100 mA, and V_CE(sat) ≤ 0.3 V at I_C = 10 mA / I_B = 0.5 mA - used in level-shifting logic interfaces and low-power load switching.

For engineers reviewing the BCR 192T E6327 datasheet, BCR 192T E6327 pinout, BCR 192T E6327 application, or BCR 192T E6327 equivalent, this part supports discrete logic interfacing where built-in resistor networks reduce PCB footprint, simplify biasing, and improve matching between paired transistors in push-pull or complementary driver stages.

Technical Context

This device implements a monolithic dual-PNP digital transistor structure with two electrically isolated emitter-base-collector units sharing a common thermal die but no internal electrical connection. Each unit integrates precision-matched on-chip base bias resistors (R1/R2 ≈ 0.47) to enable direct TTL/CMOS-compatible input drive without external components.

It operates in common-emitter switching mode with guaranteed h_FE ≥ 70 at I_C = 5 mA / V_CE = 5 V, and exhibits f_T = 200 MHz for high-speed digital transitions. The SOT-23 package provides R_thJS ≤ 165 K/W, supporting continuous operation up to T_J = 150 °C with P_tot = 250 mW at T_S ≤ 109 °C.

FAQ

Is BCR 192T E6327 RoHS compliant and halogen-free?

Yes, BCR 192T E6327 is RoHS compliant (2011/65/EU) and halogen-free per IEC 61249-2-21. The SOT-23 package uses lead-free matte tin plating, and the die attach and molding compound meet JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements for unlimited floor life at ≤ 30 °C/60% RH.

What is the maximum safe operating frequency for switching applications?

The BCR 192T E6327 has an f_T of 200 MHz, but its practical maximum switching frequency is ~20 MHz for clean square-wave generation with <10% overshoot. This limit arises from combined effects of V_CE(sat) recovery time, C_cb charge/discharge, and layout-dependent parasitic inductance - verified via pulse testing at t_p < 300 µs and duty cycle < 2%.

Can it replace a standard 2N3906 in existing designs?

No - BCR 192T E6327 is not a drop-in replacement for 2N3906 because it integrates base bias resistors and lacks independent base access. Using it in place of a discrete PNP requires redesigning the base drive network to remove external resistors and verify logic-level compatibility, especially for active-high control schemes.

Does the dual-transistor version share a common emitter or collector?

No - the dual-transistor variant (e.g., BCR192U) features galvanic isolation between TR1 and TR2: Pin 1 = B1, Pin 2 = E1, Pin 3 = C2, Pin 4 = E2, Pin 5 = B2, Pin 6 = C1. BCR 192T E6327 is a single-transistor variant in SOT-23, with no internal second transistor or shared terminals.
