Product details

Overview

BCR183E6433HTMA1 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 AEC-Q101 qualification.

For engineers reviewing the BCR183E6433HTMA1 datasheet, BCR183E6433HTMA1 pinout, BCR183E6433HTMA1 application, or BCR183E6433HTMA1 equivalent, this part serves as a single-chip, resistor-equipped PNP switch optimized for level translation, GPIO interfacing, and low-power load control in space-constrained PCBs.

Technical Context

This device integrates two matched PNP transistors in one SC74 (SOT-363) package with isolated die and symmetrical pinout. Its built-in R1/R2 network enables direct logic-level drive without external base resistors, supporting common-emitter switching with defined turn-on/off thresholds (V_i(on) = 1–2.5 V, V_i(off) = 0.8–1.8 V).

Thermal performance is specified per junction-to-soldering-point resistance (R_thJS ≤ 133 K/W), with total power dissipation rated at 250 mW at T_S ≤ 118 °C. Electrical behavior is characterized across –40 °C to +125 °C, including h_FE variation with I_C and temperature-dependent V_CE(sat) and V_i(on).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum allowable collector-emitter voltage before breakdown; supports 24 V system interfaces with margin.
I_C	100 mA - Continuous collector current rating; suitable for driving LEDs, relays, or small solenoids.
V_CE(sat)	≤ 0.3 V @ I_C/I_B = 20 - Low saturation voltage minimizes power loss and self-heating in on-state switching.
R1, R2	10 kΩ ±30% - Integrated base bias resistors eliminate external components and reduce PCB footprint.
f_T	200 MHz typ. - Sufficient gain-bandwidth for fast digital switching up to ~10 MHz edge rates.
AEC-Q101	Qualified - Meets stress-test requirements for automotive electronics, enabling use in under-hood and body-control modules.

Pinout & Package

BCR183E6433HTMA1 is housed in an SC74 (SOT-363) surface-mount package - a 6-pin, dual-transistor configuration with symmetrical pin assignment and no defined Pin 1 orientation in tape-and-reel.

Pin/Terminal	Circuit Role	Design Meaning
1 (B)	Base of TR1	Direct connection to internal R1–R2 divider node; accepts logic-level input for TR1.
2 (E1)	Emitter of TR1	Common emitter terminal for first transistor; referenced to system ground or negative rail.
3 (C2)	Collector of TR2	Output node for second transistor; sinks current when TR2 is active.
4 (E2)	Emitter of TR2	Emitter of second transistor; electrically isolated from E1 for independent circuit paths.
5 (B2)	Base of TR2	Input for TR2, biased via same R1–R2 network; enables synchronized or independent control.
6 (C1)	Collector of TR1	Primary output collector for TR1; used for high-side or low-side switching depending on topology.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP digital transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCR193E6327HTMA1	NPN polarity; identical R1/R2 values and SC74 package; V_CEO = 50 V, I_C = 100 mA.	Requires inverted logic drive and complementary load topology (high-side vs. low-side switching).	Select when sourcing current from V_CC rather than sinking to GND.
NSVD2101PT3G	Single PNP digital transistor (SOT-23); R1 = 10 kΩ, R2 = 10 kΩ; V_CEO = 50 V, I_C = 100 mA; no dual-transistor option.	Limited to single-channel use; lacks matched dual-device thermal coupling and footprint symmetry.	Choose for cost-sensitive, space-constrained single-switch designs where dual functionality is unnecessary.

Compared with BCR193E6327HTMA1 and NSVD2101PT3G, BCR183E6433HTMA1 uniquely delivers dual, matched PNP switching in one AEC-Q101-qualified SC74 package-enabling compact, thermally stable, and functionally redundant implementations not possible with single-transistor or NPN alternatives.

FAQ

What is the pin 1 marking convention for BCR183E6433HTMA1 in tape-and-reel packaging?

BCR183E6433HTMA1 uses laser marking with type code "BCR183" and date code (YY/MM) on the top surface. Per Infineon's SC74 specification, symmetric dual-transistor variants like this have no defined Pin 1 orientation in reel-orientation must be verified optically or electrically during placement.

Does BCR183E6433HTMA1 support 3.3 V microcontroller logic drive directly?

Yes. With V_i(on) = 1–2.5 V and V_i(off) = 0.8–1.8 V, BCR183E6433HTMA1 reliably switches on with standard 3.3 V CMOS logic outputs and remains fully off with logic-low levels down to 0.4 V, eliminating need for level-shifter circuitry.

How does thermal derating work for BCR183E6433HTMA1 at elevated board temperatures?

At T_S = 118 °C, P_tot is rated at 250 mW. Derating follows a linear curve: for every 1 °C above 118 °C, power must decrease by ~2.1 mW/°C (based on R_thJS ≤ 133 K/W). Full derating data is provided in Figure 5 of the official datasheet.

Can BCR183E6433HTMA1 replace discrete BJT + two resistors in existing designs?

Yes-direct replacement is supported. Pin-compatible with SC74 footprints, it replicates the function of a PNP BJT with 10 kΩ base resistors. Layout changes are limited to removing two 0603/0805 resistors and adjusting trace routing to match the 6-pin mapping.
