Product details
Overview
BCP 56-10 H6433 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 rating of 1 A, DC current gain (hFE) of 63–100 at IC = 150 mA, VCE = 2 V, and low VCE(sat) of 0.5 V at IC = 500 mA / IB = 50 mA. It is used in automotive amplifier output stages requiring high-current capability and thermal robustness.
For engineers reviewing the BCP 56-10 H6433 datasheet, BCP 56-10 H6433 pinout, BCP 56-10 H6433 application, or BCP 56-10 H6433 equivalent, key selection criteria include VCEO = 80 V, IC = 1 A, hFE range, SOT223 thermal performance, and complementary PNP pairing with BCP52/BCP53 series.
Technical Context
This transistor operates as a medium-power general-purpose NPN switch or linear amplifier with fixed emitter-base and collector-base junction structures optimized for stable hFE across IC = 5 mA to 500 mA. Its VCE(sat) ≤ 0.5 V at rated drive ensures low conduction loss in Class AB output stages.
The device uses a planar epitaxial base structure with integrated emitter ballasting, enabling consistent gain linearity and safe operating area (SOA) compliance up to TJ = 150 °C. Thermal resistance RthJS ≤ 15 K/W supports board-level heatsinking via the exposed collector tab in SOT223.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum allowable collector-emitter voltage before avalanche breakdown under open-base conditions |
| IC (continuous) | 1 A - Continuous collector current handling capacity at TS ≤ 120 °C, defining usable load drive capability |
| hFE | 63–100 - DC current gain at IC = 150 mA, VCE = 2 V, determining required base drive for saturation |
| VCE(sat) | ≤ 0.5 V - Collector-emitter voltage drop at IC = 500 mA / IB = 50 mA, directly impacting power dissipation in switching mode |
| fT | 100 MHz - Transition frequency at IC = 50 mA, VCE = 10 V, indicating usable bandwidth for AF amplification |
| RthJS | ≤ 15 K/W - Junction-to-soldering-point thermal resistance, enabling thermal design using PCB copper area as heatsink |
| Ptot | 2 W - Total power dissipation limit at TS = 120 °C, governing maximum steady-state heat generation |
Pinout & Package
BCP 56-10 H6433 is housed in a surface-mount SOT223 package with an exposed collector tab for thermal conduction. Pin 1 = Base, Pin 2 = Collector (tab), Pin 3 = Emitter, Pin 4 = Collector (second lead); pins 2 and 4 are internally connected and electrically identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Base | Control terminal; requires ~50 mA base current to saturate 500 mA collector current |
| Pin 2 & Pin 4 | Collector | Power output terminal; both leads tied internally to exposed metal tab for thermal and electrical connection |
| Pin 3 | Emitter | Reference terminal; typically grounded or connected to load return path in common-emitter configuration |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified for automotive-grade reliability per stress test requirements including HTOL, TC, and HAST |
| RoHS-compliant packaging | Lead-free solderable SOT223 package meeting EU Directive 2011/65/EU without exemptions |
| Complementary PNP pairing | Designed for direct use with BCP52/BCP53 series in push-pull output stages |
| High fT / low VCE(sat) balance | 100 MHz fT enables clean AF signal amplification while maintaining <0.5 V conduction loss |
Applications
| Automotive Audio Amplifier Output Stage | Industrial Linear Power Regulator Pass Element |
|---|---|
Use Scenario: Final output stage in Class AB car radio amplifiers driving 4 Ω speakers at up to 10 W. IC Role / Device Role / Timing Role: NPN power switch amplifying audio signal swing with minimal crossover distortion. Use Value: 80 V VCEO withstands automotive load-dump transients; 1 A IC supports peak speaker current demands. | Use Scenario: Series pass transistor in adjustable 0–30 V, 1 A bench power supply. IC Role / Device Role / Timing Role: Linear regulator control element dissipating excess input-output differential voltage. Use Value: Low VCE(sat) reduces dropout voltage; RthJS ≤ 15 K/W allows compact heatsink integration on PCB. |
| DC Motor Driver Half-Bridge Upper Switch | LED Constant-Current Driver for High-Brightness Arrays |

IC Role / Device Role / Timing Role: Linear current-regulating element controlled by op-amp feedback loop. Use Value: Tight hFE tolerance (63–100) enables predictable current mirror accuracy; SOA supports continuous operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP56-16 | Same VCEO, VCBO, IC, but hFE = 100–160 at IC = 150 mA; higher gain bin | Preferred where lower base drive current is needed; may require bias adjustment in existing designs | Select when tighter hFE consistency or reduced base current is critical |
| MJD112G | Higher VCEO = 100 V, same IC = 1 A, but hFE = 1000–3000 at IC = 150 mA; Darlington architecture | Not suitable for high-speed switching due to slower fT; introduces higher VCE(sat) (~1.5 V) | Choose only if ultra-high gain is prioritized over speed and conduction loss |
Compared with BCP56-10 H6433, BCP56-16 offers higher and more consistent hFE for reduced base drive, while MJD112G delivers extreme gain at the cost of speed and saturation voltage-making BCP56-10 the balanced choice for AF switching and linear applications demanding both efficiency and bandwidth.

FAQ
Is BCP 56-10 H6433 pin-compatible with BCP54 or BCP55?
Yes - all BCP54–BCP56 variants share identical SOT223 pinout (Pin 1 = Base, Pins 2 & 4 = Collector, Pin 3 = Emitter) and mechanical footprint. However, VCEO differs (45 V / 60 V / 80 V), so substitution requires verification of voltage margin in the target circuit.
What is the maximum safe operating temperature for continuous operation?
The junction temperature must not exceed 150 °C. With RthJS ≤ 15 K/W and Ptot = 2 W at TS = 120 °C, the device remains within safe limits when mounted on ≥ 25 mm² of 2 oz copper with thermal vias, assuming ambient ≤ 85 °C.
Does BCP 56-10 H6433 support pulse operation beyond its DC ratings?
Yes - the datasheet specifies ICM = 1.5 A for tp ≤ 10 ms with duty cycle D < 2%. Pulse derating curves confirm permissible peak power scaling down to 10 µs pulses, provided average power stays within 2 W thermal limits.
Can it be used in complementary symmetry amplifier designs?
Yes - BCP 56-10 H6433 is explicitly designed as the NPN counterpart to PNP types BCP51–BCP53. Matching hFE ranges and thermal characteristics enable symmetrical push-pull output stages with minimized crossover distortion.
