Infineon Technologies BCR183E6359HTMA1

Overview

BCR183E6359HTMA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 10 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, and is AEC-Q101 qualified.

For engineers reviewing the BCR183E6359HTMA1 datasheet, BCR183E6359HTMA1 pinout, BCR183E6359HTMA1 application, or BCR183E6359HTMA1 equivalent, key selection factors include its dual-transistor matched pair configuration (BCR183S/U variant), SC74 package thermal resistance (R_thJS ≤ 133 K/W), and guaranteed input voltage thresholds (V_i(on) = 1–2.5 V, V_i(off) = 0.8–1.8 V).

Technical Context

This device integrates two electrically isolated PNP transistors in a single SC74 (SOT-363) package with tightly matched characteristics-critical for differential sensing, push-pull drivers, and redundant logic interfaces. Its built-in R1/R2 bias network (7–13 kΩ, ratio 0.9–1.1) eliminates external base resistors and ensures consistent turn-on/turn-off behavior across temperature.

The transistor operates with a minimum DC current gain (h_FE) of 30 at I_C = 5 mA / V_CE = 5 V, supports f_T up to 200 MHz, and maintains stable V_CE(sat) ≤ 0.3 V under pulsed and continuous conditions 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 (T_J) is 150 °C. At ambient temperatures above 85 °C, derating is required: total power dissipation drops linearly from 250 mW at T_S = 118 °C to zero at 150 °C. This ensures reliability in under-hood automotive applications where board temperature can reach 125 °C.

Can BCR183E6359HTMA1 be used with 3.3 V microcontroller GPIOs without external components?

Yes. With V_i(on) = 1–2.5 V and V_i(off) = 0.8–1.8 V, the device reliably switches on with standard 3.3 V CMOS logic outputs and remains fully off during MCU reset or low-power states - no pull-up/down resistors or level shifters are needed.

How is thermal performance validated for this SC74 package?

Thermal resistance R_thJS is measured per JEDEC JESD51-14 and specified as ≤133 K/W for the BCR183U variant (which matches BCR183E6359HTMA1's SC74 footprint). This value was confirmed using transient dual-interface testing on production lots, enabling accurate junction temperature prediction in real-world PCB layouts.

Is there functional difference between BCR183E6359HTMA1 and BCR183S or BCR183U variants?

BCR183E6359HTMA1 is the SC74-packaged BCR183U variant. It shares identical electrical specs and pinout with BCR183U, differing only in reel packaging and date-code marking format. BCR183S uses the same die but in SOT-363 with different thermal specs (R_thJS ≤140 K/W); BCR183 and BCR183W use SOT-23 and SOT-323 packages respectively.
