Infineon Technologies BCR192E6327HTSA1

Overview

BCR192E6327HTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = 22 kΩ, R2 = 47 kΩ), designed for switching, inverting, interface, 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 BCR192E6327HTSA1 datasheet, BCR192E6327HTSA1 pinout, BCR192E6327HTSA1 application, or BCR192E6327HTSA1 equivalent, key selection criteria include built-in resistor ratio (R1/R2 = 0.47), thermal resistance (R_thJS ≤ 240 K/W for SOT23), input voltage thresholds (V_i(on) = 0.8–2.5 V, V_i(off) = 0.5–1.2 V), and RoHS-compliant SOT23 packaging.

Technical Context

This digital transistor integrates two precision bias resistors to enable direct logic-level drive without external components. Its PNP configuration supports high-side switching in 3.3 V/5 V interface circuits, with guaranteed DC current gain (h_FE ≥ 70 at I_C = 5 mA, V_CE = 5 V) and low saturation voltage for efficient power control.

Thermal performance is defined by junction-to-solder-point resistance (R_thJS ≤ 240 K/W for SOT23), enabling stable operation up to T_j = 150 °C. The device meets AEC-Q101 stress testing requirements for automotive under-hood applications, including temperature cycling and humidity bias.

FAQ

What is the maximum allowable continuous collector current for BCR192E6327HTSA1?

The absolute maximum continuous collector current is 100 mA at case temperature ≤ 102 °C for the SOT23 package. Derating is required above this temperature per the P_tot vs. T_S curve; at 125 °C case temperature, maximum I_C drops to approximately 65 mA to maintain safe junction temperature.

Does BCR192E6327HTSA1 require external base resistors?

No. It integrates R1 = 22 kΩ and R2 = 47 kΩ on-chip, forming a complete bias network between base and emitter. This allows direct connection to 3.3 V or 5 V logic outputs without external components, simplifying design and improving board-level reliability.

Is BCR192E6327HTSA1 suitable for PWM-driven loads?

Yes. With f_T = 200 MHz typ. and t_on/t_off in the nanosecond range, it supports PWM frequencies up to 10 MHz. For 100 kHz–1 MHz motor or LED dimming, its low V_CE(sat) and fast switching minimize conduction and transition losses.

How does the AEC-Q101 qualification impact BCR192E6327HTSA1's use in industrial applications?

AEC-Q101 qualification ensures robustness against mechanical shock, temperature cycling, and humidity exposure beyond standard industrial requirements. While not mandatory for industrial use, it provides proven reliability in vibration-prone environments like factory automation and transportation equipment.
