Infineon Technologies BCR192E6785HTSA1

Overview

BCR192E6785HTSA1 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, h_FE ≥ 70, and AEC-Q101 qualification.

For engineers reviewing the BCR192E6785HTSA1 datasheet, BCR192E6785HTSA1 pinout, BCR192E6785HTSA1 application, or BCR192E6785HTSA1 equivalent, this part serves as a pre-biased PNP switch optimized for low-power logic-level interfacing, load driving, and signal inversion where space-constrained SOT23 packaging and guaranteed DC gain are critical.

Technical Context

This device integrates two on-chip resistors to form a monolithic PNP transistor with base bias network, eliminating external components in simple switching configurations. Its common-emitter operation supports direct TTL/CMOS logic drive without additional base resistors.

The internal R1–R2 network sets predictable turn-on/off thresholds (V_i(on) = 0.8–2.5 V, V_i(off) = 0.5–1.2 V) and ensures stable saturation under varying temperature (–40 °C to 125 °C) and supply conditions, with f_T = 200 MHz enabling reliable high-speed switching up to ~10 MHz.

FAQ

What is the maximum operating temperature for BCR192E6785HTSA1?

The junction temperature (T_j) rating is 150 °C, and the device is specified for continuous operation up to 125 °C ambient when mounted on a standard FR-4 PCB with 1 cm² copper pad. Derating begins at T_S > 102 °C per the P_tot vs. T_S curve for the SOT23 package.

Can BCR192E6785HTSA1 replace a standard PNP BJT like BC807?

No - BCR192E6785HTSA1 includes integrated base bias resistors (R1 = 22 kΩ, R2 = 47 kΩ), whereas BC807 is a bare transistor requiring external biasing. Direct substitution would cause incorrect biasing and potential saturation failure unless the external resistor network is removed.

Is BCR192E6785HTSA1 suitable for PWM motor control?

Yes - with f_T = 200 MHz and V_CE(sat) ≤ 0.3 V, it supports PWM frequencies up to 25 kHz for small DC fans or solenoids. However, it is not rated for continuous motor stall currents above 100 mA; thermal limits must be verified per PCB layout and duty cycle.

Does BCR192E6785HTSA1 support reverse-voltage protection on its input?

No - the input (pin 1) connects directly to the base-emitter junction through R1. Reverse input voltage exceeding V_EB(rev) = 10 V (per datasheet) risks damaging the internal E-B junction. External clamping diodes are required if bidirectional signal lines or negative transients are expected.
