Infineon Technologies BCR141WH6327XTSA1

Overview

BCR141WH6327XTSA1 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 22 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 ≥ 50, and AEC-Q101 qualification.

For engineers reviewing the BCR141WH6327XTSA1 datasheet, BCR141WH6327XTSA1 pinout, BCR141WH6327XTSA1 application, or BCR141WH6327XTSA1 equivalent, this part supports robust low-side switching in 12 V automotive subsystems, logic-level interfacing with microcontrollers, and space-constrained PCB designs requiring built-in biasing and RoHS-compliant packaging.

Technical Context

This device integrates two matched NPN transistors in a single SC74 (SOT-363) package with isolated die and symmetrical pinout. Its internal R1/R2 resistor ratio (0.9–1.1) ensures consistent turn-on/off thresholds across temperature.

The transistor operates with guaranteed DC current gain (h_FE ≥ 50 at I_C = 5 mA, V_CE = 5 V) and low saturation voltage (V_CE(sat) ≤ 0.3 V), enabling efficient switching in 5–12 V logic-driven loads while maintaining thermal stability up to T_j = 150 °C.

FAQ

What is the maximum junction temperature and how does it affect continuous operation?

The absolute maximum junction temperature is 150 °C. At ambient temperatures above 85 °C, derating applies: total power dissipation must be reduced linearly from 250 mW at T_S = 124 °C down to zero at 150 °C. This ensures safe operation in engine bay or enclosed industrial enclosures.

Can BCR141WH6327XTSA1 replace a standard BJT like BC847 without circuit modification?

No-this is a digital transistor with internal 22 kΩ bias resistors. Replacing a discrete BJT requires removing external base resistors and verifying that the resulting input threshold (Vi(on) = 1–2.5 V) matches the driving source's logic levels and fan-out capability.

Is the SC74 package compatible with standard SOT-363 footprints and reflow profiles?

Yes-the SC74 outline matches JEDEC MO-178 (SOT-363) mechanical dimensions. Standard lead-free reflow profiles (peak 260 °C, 30 s max) are supported, and the package is RoHS-compliant with no lead content per EU Directive 2011/65/EU.

How does the R1/R2 ratio tolerance impact switching consistency between channels?

The R1/R2 ratio is specified 0.9–1.1, ensuring ≤ ±10% mismatch in base current between TR1 and TR2. This maintains balanced turn-on timing and current sharing in dual-load applications such as push-pull drivers or redundant safety outputs.
