Product details

Overview

BCR108SE6433HTMA1 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = 2.2 kΩ, R2 = 47 kΩ), designed for switching, inverting, interfacing, and driver circuits in automotive and industrial control systems. It features dual isolated transistors in one SOT363 package, AEC-Q101 qualification, 50 V VCEO, 100 mA IC, and 0.3 V VCE(sat) at IC/IB = 20.

For engineers reviewing the BCR108SE6433HTMA1 datasheet, BCR108SE6433HTMA1 pinout, BCR108SE6433HTMA1 application, or BCR108SE6433HTMA1 equivalent, this part supports high-reliability discrete logic-level translation, LED load driving, and microcontroller GPIO interface protection in space-constrained automotive modules.

Technical Context

This dual-NPN digital transistor integrates two matched, electrically isolated transistors in a single SOT363 package, enabling compact dual-channel switching without external bias networks. Its built-in R1/R2 resistor ratio (0.047 typ.) ensures consistent turn-on/off thresholds across temperature (−40 °C to 125 °C) and process variation.

The device operates with Vi(on) = 0.5–1.1 V and Vi(off) = 0.4–0.8 V at 25 °C, supporting direct TTL/CMOS logic-level drive. Thermal resistance RthJS ≤ 140 K/W enables stable 250 mW power dissipation up to TS = 115 °C, suitable for under-hood ambient conditions.

Equivalent & Alternatives

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

Alternative PartTechnical DifferenceApplication DifferenceSelection Advice
BCR108S E6327Same die, identical R1/R2 values and pinout; differs only in tape-and-reel packaging (3,000 pcs/reel vs. 10,000 pcs/reel)No functional difference; suitable for identical use cases and PCB layoutsSelect based on volume procurement needs and assembly line reel size compatibility
NSVD108SMT1GON Semiconductor variant with R1 = 2.2 kΩ, R2 = 47 kΩ, but lower hFE min (60 vs. 70) and no AEC-Q101 qualificationLimited to commercial-temperature industrial applications; not approved for automotive ECUsUse only where automotive qualification is not required and cost sensitivity outweighs reliability assurance

Compared with BCR108SE6433HTMA1, BCR108S E6327 offers identical performance in a different reel format, while NSVD108SMT1G trades AEC-Q101 compliance and higher hFE for lower unit cost in non-automotive designs.

FAQ

Is BCR108SE6433HTMA1 pin-compatible with standard SOT363 NPN transistors?

No. While it shares the SOT363 footprint, BCR108SE6433HTMA1 has six dedicated pins for dual-transistor operation (B1/E1/C2/E2/B2/C1), unlike generic single-transistor SOT363 parts. Direct replacement requires verifying both pin mapping and internal bias network presence.

What is the maximum allowable base drive voltage for reliable operation?

The absolute maximum input reverse voltage Vi(rev) is 5 V, and input forward voltage Vi(fwd) is rated at 20 V. For safe continuous operation, keep base-emitter voltage within −5 V to +5 V; exceeding 5 V forward risks damaging the internal R1/R2 network.

Does this part support PWM switching at frequencies above 10 kHz?

Yes. With fT = 170 MHz typ. and VCE(sat) stable up to 100 mA, BCR108SE6433HTMA1 supports clean PWM switching up to at least 100 kHz. Measured ton/toff is <100 ns, making it suitable for LED dimming and motor control waveforms.

Can BCR108SE6433HTMA1 be used in linear amplifier configurations?

No. This device is optimized for saturated switching, not linear amplification. Its hFE is specified only in DC switching conditions (IC = 5 mA, VCE = 5 V), and the integrated bias resistors prevent stable bias point setting required for analog gain stages.
