Infineon Technologies BCR183E6327HTSA1

Overview

BCR183E6327HTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 10 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 BCR183E6327HTSA1 datasheet, BCR183E6327HTSA1 pinout, BCR183E6327HTSA1 application, or BCR183E6327HTSA1 equivalent, this part supports reliable low-power logic-level interfacing, discrete load switching, and space-constrained PCB designs requiring built-in biasing and automotive-grade reliability.

Technical Context

This device integrates two matched PNP transistors in a single SC74 (SOT-363) package with isolated die and symmetrical pinout. Its internal resistor network enables direct TTL/CMOS logic-level drive without external base resistors.

The transistor operates with guaranteed h_FE ≥ 30 at I_C = 5 mA / V_CE = 5 V and exhibits f_T = 200 MHz, supporting high-speed switching up to ~10 MHz in practical digital applications. Thermal resistance R_thJS ≤ 133 K/W ensures stable operation at T_S ≤ 118°C.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous collector current for BCR183E6327HTSA1?

The absolute maximum continuous collector current is 100 mA at T_S ≤ 118°C. Derating applies above this case temperature, with total power dissipation dropping linearly to zero at 150°C junction temperature. Pulse operation permits higher peak currents if duty cycle and pulse width remain within the permissible P_totmax/P_totDC curves shown in the datasheet.

Does BCR183E6327HTSA1 support bidirectional signal routing?

No - it is a unidirectional PNP switch optimized for source-type (high-side) current sinking. The internal resistor network and emitter-base diode orientation prevent reverse conduction. For bidirectional applications like analog switches or bus termination, discrete FETs or dedicated analog switches are required.

Can BCR183E6327HTSA1 replace a standard BJT like BC857 in existing designs?

Only with schematic modification: BCR183E6327HTSA1 integrates base resistors, so removing external R_B is mandatory. Also, its dual-transistor structure and SC74 pinout differ from SOT-23 BJTs. Direct drop-in replacement is not possible without layout and netlist updates to accommodate the 6-pin package and dual-channel topology.

Is the SC74 package lead-free and RoHS compliant?

Yes - BCR183E6327HTSA1 uses a Pb-free (RoHS-compliant) finish on all terminals and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1). The package material is qualified for reflow soldering up to 260°C peak temperature with standard SnAgCu profiles.
