Product details
Overview
SBCP56-10T1G from onsemi is an NPN silicon epitaxial transistor in SOT-223 package, rated for 80 VCEO, 1.0 A continuous collector current, and 1.5 W power dissipation at TA = 25°C. It delivers hFE = 40–160 (at IC = 150 mA, VCE = 2 V), VCE(sat) ≤ 0.5 V (IC = 500 mA, IB = 50 mA), and fT = 130 MHz, targeting medium-power audio amplifier stages.
For engineers reviewing the SBCP56-10T1G datasheet, pinout, applications, or equivalent options, key selection criteria include DC current gain consistency across IC = 150 mA, low saturation voltage under high-current switching, thermal resistance (RJA = 83.3°C/W), AEC-Q101 qualification status, and SOT-223 mechanical compatibility with FR-4 PCB layouts.
Technical Context
The SBCP56-10T1G operates as a general-purpose medium-power NPN switch/amplifier with defined safe operating area (SOA) up to 100 V and 1 A. Its hFE binning (−10 variant) guarantees minimum hFE = 40 at IC = 150 mA, distinguishing it from −16 (min 63) and base BCP56 (min 25).
Thermal performance is characterized by RJA = 83.3°C/W on a 1.575″ × 1.575″ FR-4 board with 0.93 in² collector pad, and maximum soldering temperature of 260°C for 10 seconds. The device supports wave and reflow soldering due to formed leads that absorb thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum collector-emitter voltage before breakdown; defines rail voltage limit in linear/switching amplifiers |
| IC | 1.0 A - Continuous DC collector current rating; sets maximum sustained load drive capability |
| PD | 1.5 W - Total power dissipation at 25°C ambient; requires thermal derating above 25°C (12 mW/°C) |
| hFE | 40–160 - DC current gain range at IC = 150 mA, VCE = 2 V; ensures predictable base drive sizing |
| VCE(sat) | ≤ 0.5 V - Collector-emitter saturation voltage at IC = 500 mA, IB = 50 mA; minimizes conduction loss in switching mode |
| fT | 130 MHz - Current-gain bandwidth product at IC = 10 mA, VCE = 5 V; supports audio-frequency amplification with margin |
Pinout & Package
Package: SOT-223 (Case 318E, Style 1), surface-mount, medium-power thermally enhanced plastic package with exposed collector tab (pins 2 and 4 internally connected to collector).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires current-limited drive (IB ≤ 50 mA typical for full saturation) |
| 2 | Collector | Main power output terminal; electrically tied to pin 4; serves as thermal and electrical interface to PCB copper pour |
| 3 | Emitter | Common return path; connects to ground or low-side reference; carries full load current |
| 4 | Collector | Secondary collector connection; enhances thermal conduction and current handling via dual-tab layout |

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 |
|---|---|---|---|
| BCP56-16T1G | Higher hFE bin: min 63 at IC = 150 mA vs. min 40 for SBCP56-10T1G; otherwise identical ratings and package | Preferred where tighter base drive tolerance or higher gain stability across temperature is required (e.g., precision bias networks) | Select when gain consistency outweighs cost sensitivity; same footprint and thermal behavior |
| ZTX653 | TO-92 package (not SOT-223); VCEO = 60 V (vs. 80 V); hFE = 100–300 at IC = 150 mA; RJA ≈ 200°C/W (higher thermal resistance) | Suitable only for low-power, non-automotive, through-hole prototyping or legacy designs with space/thermal margin | Choose only if SOT-223 is unavailable and thermal/power demands are significantly lower |
Compared with BCP56-16T1G and ZTX653, the SBCP56-10T1G offers optimal balance of automotive-grade reliability, 80 V robustness, and predictable mid-range hFE for production audio and lighting control-without over-spec'ing gain or compromising thermal performance.

FAQ
What is the guaranteed hFE range for SBCP56-10T1G?
The SBCP56-10T1G is binned to guarantee hFE ≥ 40 at IC = 150 mA and VCE = 2 V, with typical values reaching 100–160 under those conditions. This binning distinguishes it from the base BCP56 (min 25) and −16 variant (min 63), enabling precise base resistor calculation in production amplifier designs. The SBCP56-10T1G datasheet confirms this specification in the Electrical Characteristics table.
Is SBCP56-10T1G qualified for automotive use?
Yes, the SBCP56-10T1G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the onsemi datasheet under "Features" and "Ordering Information." The "S" prefix in the marking (SBCP56−10T1G) denotes automotive-grade screening and control change requirements. This makes the SBCP56-10T1G suitable for under-hood and cabin applications such as body control modules and lighting drivers.
What is the thermal resistance (RJA) of SBCP56-10T1G on a standard PCB?
The SBCP56-10T1G has a maximum junction-to-ambient thermal resistance (RJA) of 83.3°C/W when mounted on a 1.575″ × 1.575″ FR-4 board with a 0.93 in² collector pad. This value assumes surface-mount assembly and accounts for conduction through pins 2 and 4 (both connected to collector). Derating is required at 12 mW/°C above 25°C ambient, per the Thermal Characteristics table in the SBCP56-10T1G datasheet.
Can SBCP56-10T1G replace BCP56T1G in existing designs?
Yes-the SBCP56-10T1G is a direct functional and pin-compatible replacement for BCP56T1G, sharing identical SOT-223 package, pinout, absolute maximum ratings, and thermal characteristics. The only difference is hFE binning: BCP56T1G has no guaranteed minimum hFE, while SBCP56-10T1G guarantees ≥40. No PCB or schematic changes are needed when upgrading to SBCP56-10T1G for improved gain consistency.
What is the maximum peak collector current (ICM) for SBCP56-10T1G?
The SBCP56-10T1G supports a peak collector current (ICM) of 2.0 A, as specified in the Maximum Ratings table under "Collector Current - Peak (Note 1)." This rating applies under pulsed conditions per the SOA curve (Note 1), not continuous operation. For reliable long-term performance, continuous IC must remain ≤1.0 A, and pulse duty cycle must comply with thermal limits defined in the Safe Operating Area graph (Figure 8) of the SBCP56-10T1G datasheet.
