Product details
Overview
BCX56-16,147 from Nexperia is an NPN medium power transistor in SOT89 (SC-62) package, rated for 80 V VCEO, 1 A continuous collector current, and DC current gain (hFE) of 100–250 at VCE = 2 V and IC = 150 mA. It serves as a low-side switch or MOSFET driver in battery-powered power management circuits with thermal resistance as low as 93 K/W when mounted on 6 cm² copper pad.
For engineers reviewing the BCX56-16,147 datasheet, BCX56-16,147 pinout, BCX56-16,147 application, or BCX56-16,147 equivalent, this device is selected for linear voltage regulators, amplifier stages, and load-switching functions where robust 80 V breakdown and pulsed 2 A peak current capability are required under industrial ambient conditions.
Technical Context
This transistor operates as a single-element NPN bipolar junction device optimized for medium-power switching and amplification. Its design supports stable hFE across −55 °C to 150 °C junction temperature, with VBE ≤ 1 V and VCE(sat) ≤ 0.5 V at IC = 500 mA / IB = 50 mA, enabling efficient drive in low-voltage control paths.
Thermal performance is defined by three mounting configurations: standard SOT89 footprint (250 K/W), 1 cm² collector pad (132 K/W), and 6 cm² pad (93 K/W). Transition frequency fT reaches 100–180 MHz at VCE = 5 V and IC = 50 mA, supporting high-speed switching up to ~100 MHz in small-signal applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage with base open; enables use in 48 V and 60 V bus systems. |
| IC | 1 A - Continuous DC collector current rating; supports sustained load switching in power regulators. |
| hFE | 100–250 - Confirmed DC current gain range at VCE = 2 V, IC = 150 mA; ensures reliable base drive sizing. |
| Ptot | 1.35 W - Max power dissipation with 6 cm² copper pad; defines thermal headroom in PCB-constrained designs. |
| fT | 100–180 MHz - Transition frequency at VCE = 5 V, IC = 50 mA; validates suitability for RF pre-driver stages. |
| Rth(j-a) | 93 K/W - Junction-to-ambient thermal resistance with 6 cm² collector pad; critical for thermal margin calculation. |
| VCE(sat) | ≤ 0.5 V - Collector-emitter saturation voltage at IC = 500 mA, IB = 50 mA; minimizes conduction loss in switch mode. |
Pinout & Package
SOT89 (SC-62) surface-mount plastic package: 3-lead, 1.5 mm pitch, 4.5 mm × 2.5 mm × 1.5 mm body. The collector tab forms the exposed thermal pad (Pin 2), enabling direct PCB copper connection for heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (E) | Current return path; connected to ground or low-side reference in switch configurations. |
| 2 | Collector (C) | Main output terminal and thermal interface; soldered to large copper area for thermal management. |
| 3 | Base (B) | Control input; requires current-limited drive (max IB = 0.3 A) to avoid saturation delay or damage. |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | 80 V - Enables operation in 48 V industrial and telecom power rails without derating. |
| Three hFE variants | BCX56-16 offers 100–250 gain - simplifies base resistor selection for consistent switching thresholds. |
| Peak pulse current | 2 A (tp ≤ 1 ms) - Supports short-duration surge loads such as motor startup or capacitor charging. |
| Low VCE(sat) | ≤ 0.5 V at IC/IB = 10 - Reduces power loss and self-heating during active conduction. |
| Thermal optimization | 93 K/W Rth(j-a) with 6 cm² pad - Allows >1 W continuous dissipation in compact SMT layouts. |
Applications
| Linear Voltage Regulators | MOSFET Drivers |

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 |
|---|---|---|---|
| BCX56-10,147 | hFE = 63–160 (lower gain band); identical VCEO, IC, package, and thermal specs. | Suitable where lower gain reduces risk of unintended oscillation in high-impedance feedback loops. | Select when base drive current is abundant and tighter hFE tolerance is needed. |
| BCP56-16,115 | Same hFE range but TO-261AA (SOT-223) package; higher Ptot = 1.5 W; Rth(j-a) = 80 K/W with 6 cm² pad. | Better thermal performance in high-duty-cycle switching; larger footprint limits ultra-compact layouts. | Choose when >1.35 W dissipation is required and board space permits larger SMT package. |
Compared with BCX56-10,147, the BCX56-16,147 provides higher and more consistent gain for precise current control; versus BCP56-16,115, it trades thermal margin for smaller SOT89 footprint-ideal for space-constrained battery management modules.

FAQ
What is the maximum allowable base current for BCX56-16,147?
The absolute maximum DC base current is 0.3 A, and peak base current is also limited to 0.3 A for pulses ≤1 ms. Exceeding these values risks bond wire failure or gain degradation. For reliable switching, design base drive to deliver 50–100 mA at turn-on, leveraging its hFE ≥100 to sustain 1 A collector current.
Can BCX56-16,147 be used in avalanche mode?
No-BCX56-16,147 is not rated or characterized for avalanche energy handling. Its VCEO = 80 V is a DC blocking rating only; operation beyond this voltage, even briefly, may cause irreversible breakdown. Use external clamping (e.g., TVS diode) for inductive load flyback protection.
How does thermal performance change with PCB copper area?
Rth(j-a) improves from 250 K/W (standard SOT89 footprint) to 132 K/W (1 cm² collector pad) and 93 K/W (6 cm² pad). This directly increases allowable continuous power: from 0.50 W → 0.95 W → 1.35 W. Layout must match the intended copper area to achieve rated Ptot.
Is BCX56-16,147 suitable for automotive applications?
No-this part is not AEC-Q101 qualified and lacks automotive-grade screening, reliability testing, or guaranteed operation over −40 °C to +125 °C ambient. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use only in industrial, consumer, or commercial equipment.
