Infineon Technologies BCR183UE6327HTSA1

Overview

BCR183UE6327HTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 10 kΩ), designed for switching, inverting, interfacing, 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 ≥ 30, and AEC-Q101 qualification.

For engineers reviewing the BCR183UE6327HTSA1 datasheet, BCR183UE6327HTSA1 pinout, BCR183UE6327HTSA1 application, or BCR183UE6327HTSA1 equivalent, this part serves as a dual-transistor matched pair in SC74 (SOT-363) package with defined terminal roles, thermal resistance R_thJS ≤ 133 K/W, and RoHS-compliant Pb-free construction.

Technical Context

This device integrates two electrically isolated PNP transistors in a single SC74 package with tightly matched characteristics-enabling balanced current sourcing and complementary logic-level interfacing. Its built-in R1/R2 bias network (7–13 kΩ, ratio 0.9–1.1) eliminates external base resistors and ensures consistent turn-on/off behavior across temperature.

The transistor operates with V_CB = 50 V, f_T ≥ 200 MHz, C_cb ≤ 3 pF, and supports pulse operation up to D = 0.5 with derated power dissipation (P_tot = 250 mW at T_S ≤ 118 °C). Junction temperature is rated to 150 °C for sustained automotive under-hood use.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The absolute maximum junction temperature (T_j) is 150 °C. Operation must remain within the derated power envelope defined by P_tot vs. T_S, where T_S ≤ 118 °C for BCR183U. Exceeding this limit risks parametric shift and accelerated failure per AEC-Q101 stress testing requirements.

Can BCR183UE6327HTSA1 be used in linear amplification mode?

No-it is optimized for digital switching, not analog amplification. Its h_FE is specified only at I_C = 5 mA and V_CE = 5 V, and no linearity, distortion, or frequency response data is provided. Use dedicated general-purpose transistors like BC847 for linear applications.

Is the SC74 package compatible with standard SOT-363 footprints?

Yes-SC74 is the JEDEC designation for SOT-363. The mechanical outline matches IPC-7351B standard land patterns, including 0.65 mm pitch, 1.25 mm body width, and symmetric pin 1 marking. Footprint dimensions are confirmed in Infineon's EHA07183 package drawing.

How does the built-in resistor ratio affect switching performance?

The R1/R2 ratio (0.9–1.1) ensures balanced base current division between the two transistors, minimizing mismatch in turn-on delay and propagation time. This maintains timing coherence in dual-channel logic gates or mirrored driver stages without external trimming.
