Product details
Overview
BCP 56-10 E6433 from Infineon Technologies is an NPN silicon bipolar junction transistor designed for audio-frequency driver and output stages in linear and switching applications. It features a collector-emitter breakdown voltage of 80 V, continuous collector current of 1 A, DC current gain (hFE) of 63–100 at IC = 150 mA, VCE = 2 V, and low saturation voltage of ≤0.5 V at IC = 500 mA / IB = 50 mA. It is housed in a thermally enhanced SOT223 package and qualified to AEC-Q101 for automotive-grade reliability.
For engineers reviewing the BCP 56-10 E6433 datasheet, BCP 56-10 E6433 pinout, BCP 56-10 E6433 application, or BCP 56-10 E6433 equivalent, this device is selected for high-current AF amplification, discrete power switching, and complementary PNP-based push-pull output stages where VCEO ≥ 80 V and thermal robustness are required.
Technical Context
This NPN transistor operates in linear and saturated modes with verified DC current gain across IC = 5 mA to 500 mA and VCE = 2 V. Its fT of 100 MHz supports stable operation up to mid-frequency AF ranges without phase degradation.
The device uses epitaxial planar technology with a monolithic SOT223 leadframe that provides RthJS ≤ 15 K/W, enabling reliable power dissipation up to 2 W at TS ≤ 120 °C. Pin 1 is Base, Pin 2 and Pin 4 are Collector (internally connected), and Pin 3 is Emitter - confirmed by Infineon's official package outline and marking layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - supports rail voltages up to ±36 V in Class AB audio outputs without breakdown |
| IC (continuous) | 1 A - enables direct drive of 8 Ω speakers or medium-power relay coils |
| VCE(sat) | ≤0.5 V @ IC = 500 mA, IB = 50 mA - reduces conduction loss and self-heating in switching mode |
| hFE | 63–100 @ IC = 150 mA, VCE = 2 V - ensures predictable base drive sizing for stable biasing |
| fT | 100 MHz - preserves signal integrity in wideband AF preamp and driver stages |
| RthJS | ≤15 K/W - allows 2 W dissipation with ≤30 K rise from solder point, critical for PCB-mounted thermal design |
| Ptot | 2 W @ TS ≤ 120 °C - defines maximum steady-state power handling on standard FR4 with copper pour |
Pinout & Package
The BCP 56-10 E6433 is packaged in SOT223, a surface-mount, thermally optimized 4-pin outline with two Collector terminals (Pins 2 and 4) internally bonded for improved current sharing and thermal path efficiency.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Base | Control terminal; requires current-limited drive (max IB = 100 mA DC) to avoid secondary breakdown |
| Pin 2 | Collector | Main high-current output node; electrically tied to Pin 4 for parallel current routing and lower effective RDS(on)-like resistance |
| Pin 3 | Emitter | Reference terminal; must be low-inductance grounded or connected to load return for stable hFE and fT |
| Pin 4 | Collector | Redundant Collector connection; used with Pin 2 to reduce thermal resistance and improve current derating margin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments including temperature cycling, humidity, and mechanical shock |
| Complementary PNP pairing | Designed as NPN counterpart to BCP51–BCP53 series for matched push-pull output stages |
| Low VCE(sat) | ≤0.5 V enables >90% efficiency in Class D gate drivers and linear regulator pass elements |
| Pb-free / RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C) |
| High fT stability | Maintains ≥100 MHz across IC = 10–100 mA, supporting clean transient response in AF feedback loops |
Applications
| Audio Power Amplifier Output Stage | Automotive Door Lock Actuator Driver |
|---|---|
Use Scenario: Final push-pull pair in 10 W Class AB amplifier driving 4–8 Ω speakers. IC Role / Device Role / Timing Role: NPN half of complementary output stage; handles positive half-cycle current delivery with minimal crossover distortion. Use Value: 80 V VCEO accommodates 24 V supply rails with headroom; 1 A IC sustains peak speaker current without thermal foldback. | Use Scenario: Discrete switch controlling 12 V DC motor in vehicle door lock mechanism. IC Role / Device Role / Timing Role: High-side or low-side current switch; interfaces microcontroller GPIO to inductive load via base resistor network. Use Value: ≤0.5 V VCE(sat) limits power loss to <125 mW at 250 mA, eliminating need for heatsink in sealed actuator housing. |
| Industrial Fan Speed Controller | DC-DC Converter Pass Transistor |
Use Scenario: Linear current regulator modulating 24 V, 500 mA cooling fan based on analog tachometer feedback. IC Role / Device Role / Timing Role: Series pass element operating in active region; dissipates variable power as speed command changes. Use Value: 2 W Ptot and RthJS ≤15 K/W allow full-speed operation at 70 °C ambient without derating. | Use Scenario: Adjustable linear post-regulator following buck converter to achieve ultra-low-noise 3.3 V supply for RF front-end. IC Role / Device Role / Timing Role: Emitter-follower pass transistor; rejects ripple from upstream switching stage while maintaining tight VOUT regulation. Use Value: hFE ≥63 ensures stable loop gain with minimal base drive error; low VBE(ON) (~0.85 V) preserves dropout margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP56-16 E6327 | Higher hFE (100–160 @ IC = 150 mA); otherwise identical VCEO, IC, VCE(sat), and package | Preferred where precise base current control is needed (e.g., current mirrors, low-gain feedback paths) | Select BCP56-16 when tighter hFE tolerance improves bias stability; BCP56-10 remains optimal for cost-sensitive, high-volume AF output stages |
| MJD112G | TO-252 package; higher IC (2 A), higher VCEO (100 V), but lower fT (30 MHz) and no AEC-Q101 qualification | Suitable for non-automotive industrial switching where thermal mass matters more than frequency response | Choose MJD112G only if board space permits TO-252 and AEC-Q101 compliance is not required; BCP56-10 retains advantage in SMT density and automotive qualification |
Compared with BCP56-16 E6327 and MJD112G, the BCP56-10 E6433 offers the best balance of automotive qualification, SOT223 footprint, and sufficient hFE for robust base drive in cost-constrained AF and actuator circuits - making it the default choice for OEM-tier automotive electronics and compact industrial controls.

FAQ
Is BCP 56-10 E6433 pin-compatible with BCP56-16?
Yes - both share identical SOT223 pinout (Pin 1 = Base, Pins 2 & 4 = Collector, Pin 3 = Emitter) and mechanical footprint. The only functional difference is hFE binning: BCP56-10 specifies 63–100, while BCP56-16 specifies 100–160. No PCB redesign is needed for substitution.
What is the maximum safe operating area (SOA) limit at 25°C?
At TC = 25°C, the SOA is defined by IC ≤ 1 A and VCE ≤ 80 V under DC conditions. For pulsed operation (tp ≤ 10 ms, duty cycle < 2%), ICM reaches 1.5 A. Derating is required above 25°C per the Ptot vs. TS curve in Infineon's Application Note AN077.
Can BCP 56-10 E6433 replace BC817 in high-current applications?
No - BC817 is rated for IC = 500 mA and VCEO = 45 V in SOT23. BCP56-10 supports 1 A and 80 V in SOT223, offering 2× current capacity and 1.8× voltage rating. Substitution requires verifying PCB pad layout, thermal relief, and base drive capability due to different package and gain profile.
Does this part support lead-free reflow soldering?
Yes - BCP 56-10 E6433 is Pb-free and RoHS compliant. It is qualified for standard lead-free reflow profiles with peak temperature up to 260 °C (per JEDEC J-STD-020), and its SOT223 package withstands thermal cycling without delamination or bond wire failure.
