Product details
Overview
BCR198E6393HTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 47 kΩ), designed for switching, inverting, interface, and 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, hFE ≥ 70, and AEC-Q101 qualification.
For engineers reviewing the BCR198E6393HTSA1 datasheet, BCR198E6393HTSA1 pinout, BCR198E6393HTSA1 application, or BCR198E6393HTSA1 equivalent, key selection criteria include built-in resistor matching, thermal derating curves for SOT23, DC current gain stability across −40°C to 125°C, and input voltage thresholds for reliable logic-level interfacing.
Technical Context
This device integrates two matched PNP transistors in a single SOT23 package, enabling compact dual-channel switching without external bias networks. Its internal R1/R2 ratio of 0.9–1.1 ensures consistent turn-on/off behavior between channels under varying temperature and supply conditions.
The transistor operates with Vi(on) = 1–3 V and Vi(off) = 0.8–1.5 V, supporting direct connection to 3.3 V and 5 V logic families. Thermal resistance RthJS ≤ 240 K/W enables stable operation up to TS = 102°C before power derating begins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V industrial bus and 12 V automotive loads. |
| IC | 100 mA - Continuous collector current rating; suitable for driving relays, LEDs, and small solenoids. |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| hFE | ≥ 70 at IC = 5 mA/VCE = 5 V - Sufficient DC gain for robust digital switching with margin against temperature drift. |
| R1 / R2 | 32–62 kΩ / ratio 0.9–1.1 - Matched internal bias network eliminates discrete resistor layout and improves channel-to-channel consistency. |
| fT | 190 MHz typical - Enables high-speed switching up to ~10 MHz with controlled edge rates in digital interfaces. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics including temperature cycling, HTRB, and ESD. |
Pinout & Package
BCR198E6393HTSA1 is housed in a Pb-free, RoHS-compliant SOT23 package (JEDEC TO-236AB), with standard 3-pin configuration and 1.3 mm pitch. Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Base) | Input control node | Connected internally to R1 and R2; accepts logic-level voltage to enable/disable transistor conduction. |
| Pin 2 (Emitter) | Current return path | Common emitter terminal; tied to system ground or negative rail in high-side switch configurations. |
| Pin 3 (Collector) | Switched output node | Drives load between collector and positive supply; supports sink-current operation up to 100 mA. |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched PNP topology | Two electrically isolated but thermally coupled transistors in one SOT23 die; enables compact dual-channel drivers with <±5% gain matching. |
| Integrated bias network | R1 = R2 = 47 kΩ ±21%; eliminates 4 external resistors per channel and reduces PCB area by >30% vs discrete solutions. |
| Automotive-grade reliability | AEC-Q101 qualified with Tj = 150°C max and Tstg = −65…+150°C; validated for under-hood and engine-control module use. |
| Thermal derating profile | Ptot = 200 mW at TS ≤ 102°C; linear derating to zero at 150°C junction-enables accurate thermal design in sealed enclosures. |
Applications
| Automotive Door Module Control | Industrial PLC Output Stage |
|---|---|
Use Scenario: Driving window lift motors and mirror actuators via microcontroller GPIOs in door control units. IC Role / Device Role / Timing Role: High-side PNP switch providing current sinking capability with logic-level input compatibility.

IC Role / Device Role / Timing Role: Logic-compatible PNP switch enabling direct drive without level-shifting circuitry. Use Value: VCE(sat) ≤ 0.3 V limits power dissipation to <3 mW at 10 mA load, minimizing thermal impact on adjacent analog sensors. | Use Scenario: Enabling/disabling low-power analog sensor excitation circuits (e.g., RTD biasing) in portable diagnostic equipment. IC Role / Device Role / Timing Role: Precision-controlled current switch with tight R1/R2 matching ensuring identical turn-on timing across dual sensor channels. Use Value: Matched hFE and thermal tracking reduce channel-to-channel offset drift below 0.1% over −25°C to +85°C operating range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR198W | SOT323 package; higher Ptot = 250 mW at TS ≤ 124°C; same R1/R2 values and electrical specs. | Better thermal performance in higher ambient or higher duty-cycle applications; requires different footprint. | Select when board space allows SOT323 and thermal margin is critical. |
| BCR198S | SOT363 package; dual-transistor variant with 6-pin layout (E1/B1/C1/E2/B2/C2); identical per-transistor specs. | Enables independent control of two loads; pinout incompatible with BCR198E6393HTSA1's 3-pin SOT23. | Choose for dual-channel designs where space permits and separate base control is required. |
Compared with BCR198W and BCR198S, BCR198E6393HTSA1 offers optimal balance of compact SOT23 footprint, automotive qualification, and proven thermal behavior in cost-sensitive single-channel switching applications.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature Tj is 150°C. Operation must remain within the derated power envelope defined by Ptot vs. TS, where full 200 mW is permitted only when solder point temperature TS ≤ 102°C. Exceeding this requires linear derating per the datasheet curve.
Is BCR198E6393HTSA1 compatible with lead-free reflow soldering processes?
Yes. The device uses a Pb-free, RoHS-compliant SOT23 package qualified for standard lead-free reflow profiles (J-STD-020, peak temperature ≤ 260°C). Moisture sensitivity level is MSL1, eliminating bake requirements prior to assembly.
Can this transistor be used in linear amplifier configurations?
No. BCR198E6393HTSA1 is optimized for digital switching operation. Its integrated bias resistors and specified hFE min/max range are intended for saturated on/off states-not linear gain control. Use BC856 or similar general-purpose PNP transistors for analog amplification.
How does the built-in resistor network affect input impedance?
The R1–R2 divider presents an effective input impedance of ~23.5 kΩ (R1||R2) at the base terminal. This provides predictable current sourcing from logic drivers while maintaining noise immunity-no external pull-up/down resistors are needed for standard 3.3 V or 5 V CMOS outputs.
