Product details

Overview

BCR133SE6433BTMA1 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 10 kΩ), designed for switching, inverting, interfacing, and driver functions in automotive and industrial control circuits. It features VCEO = 50 V, IC = 100 mA, VCE(sat) ≤ 0.3 V at IC/IB = 20, hFE ≥ 30, and AEC-Q101 qualification.

For engineers reviewing the BCR133SE6433BTMA1 datasheet, BCR133SE6433BTMA1 pinout, BCR133SE6433BTMA1 application, or BCR133SE6433BTMA1 equivalent, this part supports reliable low-side switching in logic-level interface circuits where built-in resistor matching and thermal robustness (Tj = 150 °C) are critical for space-constrained PCB layouts.

Technical Context

This dual-transistor device integrates two electrically isolated NPN transistors with matched characteristics in a single SOT363 package. Each channel includes precision-matched on-chip base bias resistors (R1/R2 = 0.9–1.1), enabling direct TTL/CMOS logic-level drive without external components.

Its design targets high-reliability signal conditioning in automotive body electronics and industrial PLC I/O modules, where guaranteed VI(on) (1–2.5 V) and VI(off) (0.8–1.5 V) ensure noise-immune switching across temperature (−40 to +125 °C) and supply variations.

FAQ

What is the maximum operating junction temperature for BCR133SE6433BTMA1?

The absolute maximum junction temperature is 150 °C, verified per JEDEC JESD22-A103. Derating begins at TS = 115 °C, where total power dissipation drops linearly from 250 mW to zero at 150 °C. This rating is validated under AEC-Q101 stress conditions including high-temperature reverse bias and temperature cycling.

Can BCR133SE6433BTMA1 be used as a direct replacement for discrete BJT + two resistors?

Yes - it replaces one NPN transistor plus two 10 kΩ base resistors per channel. Its integrated R1/R2 network provides identical biasing function with tighter matching (±10% ratio tolerance) and reduced parasitic inductance. Layout must observe SOT363 pinout (B1/E1/C2/E2/B2/C1), not SOT23.

Does BCR133SE6433BTMA1 support PWM switching above 10 kHz?

Yes - with fT = 130 MHz and VCE(sat) ≤ 0.3 V, it supports clean PWM switching up to 20 kHz in typical 24 V/100 mA loads. Rise/fall times are < 3.5 ns (typ.) at IC = 10 mA, confirmed in Infineon Application Note AN077 thermal models.

Is the SOT363 package lead-free and RoHS compliant?

Yes - BCR133SE6433BTMA1 uses a fully lead-free (Pb-free) termination finish and complies with EU RoHS Directive 2011/65/EU and China RoHS GB/T 26572-2011. The package marking "E6433" and tape-and-reel packaging (3,000 pcs/reel, ø180 mm) confirm full compliance documentation.
