Product details
Overview
BCR148SE6433HTMA1 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 47 kΩ), designed for switching, inverter, and interface driver circuits in automotive and industrial control systems. It features VCEO = 50 V, IC = 100 mA, VCE(sat) ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA, and AEC-Q101 qualification.
For engineers reviewing the BCR148SE6433HTMA1 datasheet, BCR148SE6433HTMA1 pinout, BCR148SE6433HTMA1 application, or BCR148SE6433HTMA1 equivalent, this part serves as a dual-transistor matched pair in SOT363 package with defined input threshold behavior (Vi(on) = 1–3 V, Vi(off) = 0.8–1.5 V) and thermal resistance RthJS ≤ 140 K/W.
Technical Context
This device integrates two electrically isolated NPN transistors with tightly matched hFE and VCE(sat) characteristics in a single SOT363 package. Its built-in R1/R2 bias network enables direct logic-level drive without external base resistors, supporting common-emitter switching configurations with IC up to 100 mA per transistor.
The BCR148S variant operates across –40 °C to +125 °C junction temperature, maintains fT ≥ 100 MHz at IC = 10 mA/VCE = 5 V, and exhibits Ccb = 3 pF at VCB = 10 V - enabling stable high-speed digital switching in space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - supports rail voltages up to 48 V DC systems without breakdown |
| IC | 100 mA - drives medium-current loads such as LED arrays or small relays |
| VCE(sat) | ≤ 0.3 V at IC/IB = 20 - minimizes conduction loss and self-heating in switching mode |
| R1 / R2 | 47 kΩ ±30% - provides fixed base bias for TTL/CMOS-compatible input thresholds |
| fT | ≥ 100 MHz - enables reliable operation in pulse-width modulated (PWM) control up to ~10 MHz |
| RthJS | ≤ 140 K/W - allows 250 mW total dissipation at TS ≤ 115 °C on standard FR-4 PCB |
| AEC-Q101 | Qualified - certified for automotive powertrain and body electronics applications |
Pinout & Package
BCR148SE6433HTMA1 is housed in a RoHS-compliant SOT363 (SC-88) surface-mount package with six terminals and dual-transistor layout. Pin 1 = B1, Pin 2 = E1, Pin 3 = C2, Pin 4 = E2, Pin 5 = B2, Pin 6 = C1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B1) | Base of Transistor 1 | Input node for first transistor; internally connected to R1 and R2 divider |
| 2 (E1) | Emiter of Transistor 1 | Common emitter reference for TR1; tied to PCB ground plane in typical switch configuration |
| 3 (C2) | Collector of Transistor 2 | Output node for second transistor; connects to load anode or pull-up resistor |
| 4 (E2) | Emiter of Transistor 2 | Common emitter reference for TR2; electrically isolated from E1 but same potential in dual-emitter configuration |
| 5 (B2) | Base of Transistor 2 | Input node for second transistor; shares same bias network topology as B1 |
| 6 (C1) | Collector of Transistor 1 | Output node for first transistor; used for independent switching path alongside C2 |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched NPN transistors | TR1 and TR2 share identical hFE, VCE(sat), and timing response within one die - simplifies differential or redundant switching designs |
| Integrated bias resistors | R1 = R2 = 47 kΩ - eliminates need for two external base resistors per transistor, reducing BOM count and layout area |
| Logic-compatible input thresholds | Vi(on) = 1–3 V, Vi(off) = 0.8–1.5 V - directly interfaces with 3.3 V and 5 V microcontroller GPIOs without level-shifting |
| AEC-Q101 qualified | Stress-tested for automotive environments including temperature cycling, HAST, and mechanical shock - suitable for under-hood ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR148S E6327 | Same die, identical R1/R2 values and pinout; differs only in tape-and-reel packaging (3,000 vs. 10,000 pcs/reel) | No functional difference; compatible in all PCB layouts and thermal profiles | Select based on volume procurement needs and assembly line reel size requirements |
| NSVD2101PT1G | Single-channel NPN digital transistor (R1=100 kΩ, R2=100 kΩ); higher Vi(on) (1.5–4.5 V), lower IC rating (70 mA) | Lacks dual-transistor matching; requires two devices for equivalent channel count | Use where board space permits discrete placement and higher input threshold tolerance is acceptable |
Compared with BCR148SE6433HTMA1, the E6327 variant offers identical electrical performance with different logistics packaging, while the NSVD2101PT1G trades integration density for wider input voltage margin and reduced current capability - making it suitable only when dual-transistor matching is not required.

FAQ
What is the maximum continuous collector current per transistor in BCR148SE6433HTMA1?
The absolute maximum continuous collector current is 100 mA per transistor at TS ≤ 115 °C. Derating applies above this case temperature, with total power dissipation dropping linearly to zero at 150 °C junction temperature. Pulse operation allows higher peak currents if duty cycle and pulse width remain within limits defined by the Ptotmax/PtotDC vs. tp curves in the datasheet.
Can BCR148SE6433HTMA1 be used with 1.8 V logic inputs?
No - its specified Vi(on) range is 1.0–3.0 V at IC = 2 mA, and typical turn-on occurs above 1.5 V. At 1.8 V, hFE drops significantly and VCE(sat) rises beyond 0.5 V, risking incomplete saturation. For 1.8 V systems, consider logic-level MOSFETs or dedicated level translators instead.
Is the internal resistor ratio R1/R2 guaranteed across temperature?
Yes - the R1/R2 ratio is specified as 0.9–1.1 over –40 °C to +125 °C, ensuring consistent bias network behavior across automotive operating conditions. This tight matching preserves input threshold symmetry between the two transistors even under thermal stress.
Does BCR148SE6433HTMA1 support reverse-biased operation (e.g., as a diode)?
No - the device is not characterized or rated for reverse-emitter operation. The internal resistor network and transistor structure are optimized for forward-active switching only. Applying reverse voltage beyond VEB = –10 V risks permanent damage due to uncontrolled current paths and lack of protection circuitry.
