Product details
Overview
BCP56-16HX from Nexperia is an AEC-Q101-qualified NPN medium power transistor in SOT223 (SC-73) package, rated for 80 V VCEO, 1 A continuous collector current, and 250 hFE at IC = 150 mA. It serves as a low-side switch or MOSFET driver in automotive power management systems requiring high-temperature operation up to 175 °C.
For engineers reviewing the BCP56-16HX datasheet, BCP56-16HX pinout, BCP56-16HX application, or BCP56-16HX equivalent, this device is selected for linear voltage regulators, amplifier stages, and robust switching where DC current gain stability across temperature and pulse handling capability are critical.
Technical Context
This transistor features a planar epitaxial die structure optimized for high-current gain consistency and thermal resilience. Its dual-collector pin configuration (pins 2 and 4) enables enhanced heatsinking on PCBs with extended copper pads, supporting up to 2.2 W total power dissipation under 4-layer FR4 mounting conditions.
The device operates with VBE ≤ 1 V at IC = 500 mA and exhibits fT = 155 MHz typical, enabling use in medium-frequency switching and analog amplification. Its 175 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IC (continuous) | 1 A - Continuous DC collector current rating; sufficient for driving gate capacitance of logic-level MOSFETs. |
| hFE | 100–250 - DC current gain at VCE = 2 V, IC = 150 mA; enables precise base current sizing for saturation control. |
| VCE(sat) | ≤ 500 mV - Collector-emitter saturation voltage at IC = 500 mA, IB = 50 mA; ensures low conduction loss in switching applications. |
| Ptot (max) | 2.2 W - Total power dissipation on 4-layer FR4 with 1 cm² collector pad; defines thermal design envelope for PCB layout. |
| fT | 155 MHz - Transition frequency at VCE = 5 V, IC = 50 mA; confirms usability in audio and sub-MHz signal amplification. |
| Rth(j-a) | 69 K/W - Junction-to-ambient thermal resistance on optimized 4-layer board; determines steady-state temperature rise under load. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with integrated heatsink tab (pin 2 and pin 4 both connected to collector); 4-terminal configuration optimized for thermal performance and PCB copper area utilization.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input node; requires current-limited drive to achieve target IC/IB ratio for saturation. |
| 2 | Collector | Main high-current output terminal; electrically tied to pin 4 and thermal pad for parallel current path and heat spreading. |
| 3 | Emiter | Reference/return node for collector current; must be connected to low-impedance ground plane for stable biasing. |
| 4 | Collector | Secondary collector terminal; used with pin 2 to distribute current and improve thermal coupling to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
| High-temperature operation | Junction temperature range −55 °C to +175 °C enables deployment in engine control units and powertrain modules. |
| Dual-collector thermal design | Pins 2 and 4 both connect to collector and thermal pad, allowing >2× effective heatsink area versus single-pin SOT-23 equivalents. |
| Three hFE variants | BCP56-16HX offers 100–250 hFE, enabling tighter base drive tolerance in production without binning or feedback compensation. |
| Low VCE(sat) | ≤500 mV at IC = 500 mA ensures <0.25 W conduction loss, reducing thermal stress in compact power stages. |

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 |
|---|---|---|---|
| BCP56-10H | hFE = 63–160 at IC = 150 mA; otherwise identical ratings and package. | Lower gain requires higher base drive current; less suitable for low-IO microcontroller outputs. | Select when base current budget allows ≥2× higher IB or when tighter hFE distribution is acceptable. |
| ZTX653 | TO-92 package; VCEO = 60 V; IC = 1 A; hFE = 100–300; no AEC-Q101 qualification. | Limited thermal performance (Rth(j-a) ≈ 200 K/W); unsuitable for sustained >500 mA or automotive under-hood use. | Use only in cost-sensitive, non-automotive, low-power consumer applications with ample heatsinking margin. |
Compared with BCP56-10H and ZTX653, BCP56-16HX delivers superior thermal management via SOT223 dual-collector layout, guaranteed high hFE for low-base-drive designs, and automotive-grade reliability-making it the optimal choice for space-constrained, high-reliability 24 V/48 V industrial and automotive power stages.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current (IB) is 0.2 A per datasheet Table 6. For reliable continuous operation, design base drive to maintain IB ≤ 100 mA with derating above 100 °C ambient. Exceeding 0.2 A risks metallization failure even if VBE remains within limits.
Can pins 2 and 4 be used independently for separate collector connections?
No-pins 2 and 4 are internally shorted to the same collector node and thermal pad. They must be connected to the same net on the PCB. Using them separately violates the internal construction and compromises thermal and electrical performance.
Is the marking code 'P5616H' sufficient for full traceability to BCP56-16HX?
Yes-per Table 5, 'P5616H' is the official top-side marking for BCP56-16HX. This code uniquely identifies the part number, gain grade (16), and package variant (H), and matches Nexperia's traceability system for lot-level documentation and AEC-Q101 test records.
How does thermal performance change when using only one collector pin instead of both?
Using only pin 2 or pin 4 reduces effective heatsink area by ~50%, increasing Rth(j-a) from 69 K/W to ≥125 K/W (per Table 7). This raises junction temperature by up to 55 °C at 1 A, risking thermal runaway-both pins must be soldered to the same copper pour for rated performance.
