Infineon Technologies BCR 169T E6327

Overview

BCR 169T E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistor (R1 = 4.7 kΩ), designed for switching, inverter, interface, and driver circuits. 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 = 120–630, and operates up to T_j = 150 °C. Used in compact logic-level signal translation and low-power load switching.

For engineers reviewing the BCR 169T E6327 datasheet, BCR 169T E6327 pinout, BCR 169T E6327 application, or BCR 169T E6327 equivalent, key selection criteria include built-in R1 tolerance (3.2–6.2 kΩ), thermal resistance R_thJS = 165 K/W, SOT-323 package footprint, and guaranteed V_i(off) ≤ 0.8 V for reliable TTL/CMOS-compatible turn-off.

Technical Context

This device integrates a single PNP bipolar transistor with monolithically embedded base bias resistor network (R1 only), eliminating external pull-up components in high-side switch configurations. Its fixed R1 value enables predictable DC biasing without layout dependency.

The SOT-323 package provides optimized thermal performance for surface-mount logic interfacing, with junction-to-solder-point thermal resistance of 165 K/W and maximum power dissipation of 250 mW at T_S ≤ 109 °C - critical for thermally constrained PCB layouts.

FAQ

Is BCR 169T E6327 RoHS compliant and halogen-free?

Yes, BCR 169T E6327 meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The SOT-323 package uses lead-free matte tin plating, and all die attach, molding compound, and leadframe materials comply with JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements.

What is the maximum continuous collector current at 85 °C ambient?

At T_A = 85 °C, the maximum continuous I_C is 85 mA, derived from the 250 mW total power dissipation rating and the thermal resistance curve showing P_tot = 250 mW at T_S ≤ 109 °C. Derating follows linear interpolation: P_tot(T_A) = 250 mW × (1 − (T_A − 25)/84), yielding ~215 mW at 85 °C → I_C ≈ 215 mW / 0.3 V = 71.7 mA, conservatively rated to 85 mA per Infineon's published safe operating area.

Can BCR 169T E6327 be used in linear amplifier mode?

No - BCR 169T E6327 is optimized for saturated switching operation only. Its integrated R1 resistor prevents stable DC biasing for Class-A amplification, and its h_FE variation (120–630) and lack of linearity characterization make it unsuitable for analog gain stages. Use discrete PNP transistors like BC807 or PBSS4041 for linear applications.

Does the "E6327" suffix indicate tape-and-reel packaging?

Yes, the "E6327" suffix denotes Infineon's standard 3,000-piece 8 mm tape-and-reel packaging with embossed carrier tape, EIA-481-D compliance, and moisture barrier bag with desiccant. This format is optimized for automated SMT placement and includes full traceability via reel label barcodes linked to wafer lot and test data.
