Infineon Technologies BCR 148T E6327

Overview

BCR 148T E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 47 kΩ), designed for switching, inverting, and interface driver functions in automotive and industrial control circuits. It features V_CEO = 50 V, I_C = 100 mA, V_CE(sat) ≤ 0.3 V at I_C/I_B = 20, h_FE ≥ 70, and AEC-Q101 qualification.

For engineers reviewing the BCR 148T E6327 datasheet, BCR 148T E6327 pinout, BCR 148T E6327 application, or BCR 148T E6327 equivalent, this part serves as a single-NPN bias-resistor transistor in space-constrained logic-level interface and load-switching designs requiring RoHS-compliant, thermally robust SOT23 packaging.

Technical Context

This device integrates two precision-matched on-chip resistors to form a monolithic NPN transistor with base bias network-eliminating external resistor placement while maintaining predictable turn-on/off thresholds. Its V_i(on) (1–3 V) and V_i(off) (0.8–1.5 V) enable direct TTL/CMOS logic-level drive without level-shifting circuitry.

The SOT23 package delivers R_thJS ≤ 240 K/W, supporting continuous operation up to T_J = 150 °C. Thermal derating curves confirm stable P_tot = 200 mW at T_S ≤ 102 °C, making it suitable for ambient-temperature-variable embedded control nodes.

FAQ

What is the maximum continuous collector current for BCR 148T E6327?

The absolute maximum continuous collector current is 100 mA at T_S ≤ 102 °C. Derating applies above this case temperature per the P_tot vs. T_S curve; at 125 °C ambient with typical PCB copper, usable I_C drops to ~65 mA to maintain junction temperature below 150 °C.

Can BCR 148T E6327 replace a standard BJT like BC847 in existing designs?

It can replace BC847 only if the circuit relies on external base resistors for biasing. BCR 148T E6327 integrates R1 and R2 internally-direct substitution without removing those resistors will cause over-biasing and potential saturation failure. Layout revision is required to omit external base resistors.

Is the SOT23 package of BCR 148T E6327 lead-free and RoHS compliant?

Yes-BCR 148T E6327 uses a Pb-free, RoHS-compliant SOT23 package with matte tin plating on terminals. It meets EU Directive 2011/65/EU and is marked "E6327" per Infineon's reel-labeling standard for lead-free identification.

Does BCR 148T E6327 support PWM-driven loads?

Yes-its f_T = 100 MHz and fast V_CE(sat) transition support PWM frequencies up to 10 MHz for low-duty-cycle pulse loads. For sustained 100% duty cycle at 100 mA, thermal design must limit T_S to ≤102 °C to avoid exceeding P_tot = 200 mW.
