Infineon Technologies BCR35PNH6327XTSA1

Overview

BCR35PNH6327XTSA1 from Infineon Technologies is a dual NPN/PNP silicon digital transistor array in SOT-363 package, featuring integrated bias resistors (R1 = 10 kΩ, R2 = 47 kΩ), 50 V V_CEO, 100 mA I_C, and AEC-Q101 qualification for automotive interface and switching applications.

For engineers reviewing the BCR35PNH6327XTSA1 datasheet, BCR35PNH6327XTSA1 pinout, BCR35PNH6327XTSA1 application, or BCR35PNH6327XTSA1 equivalent, this device serves as a galvanically isolated dual-transistor driver with defined input threshold voltages (V_i(on) ≤ 1.4 V, V_i(off) ≥ 0.5 V) and low saturation voltage (V_CE(sat) ≤ 0.3 V at I_C = 10 mA).

Technical Context

This dual digital transistor integrates one NPN and one PNP transistor with monolithically embedded base bias networks-R1 = 10 kΩ and R2 = 47 kΩ-enabling direct logic-level drive without external resistors. It supports complementary switching in level-shifting and push-pull configurations.

Rated for 50 V breakdown across both transistor types and operating up to 150 °C junction temperature, it delivers stable h_FE ≥ 70 at I_C = 5 mA and f_T = 150 MHz, making it suitable for high-speed interface circuits in automotive control modules.

FAQ

What is the maximum continuous collector current per transistor?

The BCR35PNH6327XTSA1 supports 100 mA DC collector current per transistor (NPN or PNP) at T_S = 115 °C. Derating applies above this temperature; at 25 °C ambient, full rating is usable with adequate PCB copper area for heat dissipation.

Can this device replace two separate single digital transistors?

Yes - its galvanically isolated NPN and PNP sections operate independently, enabling direct substitution of two discrete BCR1xx-type devices. Pin mapping differs, so PCB layout must follow SOT-363 pinout (E1/B1/C2/E2/B2/C1), not SOT-23.

Is thermal performance validated for reflow soldering?

Yes - the SOT-363 package is qualified for standard lead-free reflow profiles (JEDEC J-STD-020). R_thJS ≤ 140 K/W is measured from junction to soldering point, supporting thermal modeling using Infineon Application Note AN077.

Does the internal resistor network support PWM-driven loads?

Yes - the fixed R1/R2 values provide stable base current during PWM operation up to 100 kHz. At higher frequencies, parasitic capacitance (C_cb = 2 pF) may limit rise/fall times; verify with actual load and scope measurements.
