Infineon Technologies BCR198WE6327BTSA1

Overview

BCR198WE6327BTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = 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 BCR198WE6327BTSA1 datasheet, BCR198WE6327BTSA1 pinout, BCR198WE6327BTSA1 application, or BCR198WE6327BTSA1 equivalent, this page delivers verified package mapping (SOT-323), terminal roles, thermal resistance (R_thJS ≤ 105 K/W), input voltage thresholds (V_i(on) = 1–3 V, V_i(off) = 0.8–1.5 V), and AEC-Q101 reliability data for automotive-grade design validation.

Technical Context

This device integrates two matched PNP transistors with monolithic bias networks in a single SOT-323 package, enabling compact dual-channel logic-level switching without external resistors. Its built-in R1/R2 ratio of 0.9–1.1 ensures consistent turn-on/off behavior across temperature (−40 °C to 125 °C) and process variation.

The transistor operates in common-emitter configuration with guaranteed DC current gain (h_FE ≥ 70 at I_C = 5 mA, V_CE = 5 V) and low saturation voltage (V_CE(sat) ≤ 0.3 V), supporting high-efficiency signal inversion and load driving in space-constrained PCB layouts.

FAQ

What is the maximum continuous collector current for BCR198WE6327BTSA1?

The maximum continuous collector current is 100 mA at T_S ≤ 124 °C. Derating applies above this case temperature: total power dissipation drops linearly to zero at 150 °C junction temperature. This rating assumes proper PCB copper pour and thermal vias to maintain solder-point temperature within specification.

Does BCR198WE6327BTSA1 require external base resistors?

No. It integrates two precision bias resistors (R1 = R2 = 47 kΩ) internally, enabling direct connection to 3.3 V or 5 V logic outputs without external components. The resistor ratio tolerance (0.9–1.1) ensures stable V_i(on)/V_i(off) thresholds across temperature and process variation.

Is BCR198WE6327BTSA1 suitable for PWM-driven loads?

Yes. With f_T = 190 MHz and V_CE(sat) ≤ 0.3 V, it supports PWM frequencies up to several hundred kHz in switching applications. Its low storage time and transition capacitance (C_cb = 3 pF) minimize switching losses and ensure clean edges in LED dimming or motor control circuits.

How does the AEC-Q101 qualification impact design reuse?

AEC-Q101 qualification confirms successful completion of stress tests including HTOL, TC, HAST, and ESD (HBM ≥ 2 kV). This allows direct reuse in automotive Tier-1 modules without requalification, shortening design cycle time and reducing validation cost for body control, lighting, and sensor interface applications.
