What are the key features of ZXTN19100CFFTA?
- 100 V VCEO and 4.5 A IC rating enabling medium-power NPN switching and linear regulation in a SOT-23F footprint
- Minimum hFE of 130 ensures high base-drive efficiency, reducing required base current to under 35 mA at full collector load
- 25 pF collector-base capacitance supports fast switching transitions in motor-drive pre-driver and PWM control stages
What is ZXTN19100CFFTA used for?
ZXTN19100CFFTA is used as a medium-power switch in DC motor pre-driver stages, solenoid drivers, and LED lighting ballasts where up to 4.5 A must be switched at voltages up to 100 V from a compact SOT-23F package. Its high hFE of 130 minimum allows a microcontroller GPIO to drive the base through a simple resistor without a buffer stage. The device also suits linear pass transistors in low-dropout regulators and current-source circuits operating in the 24 V to 48 V industrial equipment range.

Frequently Asked Questions
What are the key absolute maximum ratings of ZXTN19100CFFTA for a 48 V motor-driver pre-stage?
ZXTN19100CFFTA has a collector-emitter voltage maximum of 100 V and a continuous collector current of 4.5 A, providing more than 2× voltage headroom above a 48 V supply and enough current to drive high-side gate drivers or medium-power solenoids directly. The collector-base capacitance of 25 pF allows switching transitions fast enough for PWM frequencies up to several hundred kilohertz.
How does the minimum hFE of 130 simplify the base-drive circuit for ZXTN19100CFFTA?
With a minimum DC current gain (hFE) of 130, ZXTN19100CFFTA requires a base current of only about 34 mA to saturate at full 4.5 A collector load. A single 3.3 V or 5 V microcontroller GPIO output can bias the base through a resistor of approximately 100 Ω without an additional buffer transistor, simplifying the drive circuit BOM.
Why choose ZXTN19100CFFTA's SOT-23F package over a TO-92 package for SMT board designs?
The SOT-23F flat-lead package has a footprint of approximately 3 mm × 1.75 mm versus the 5 mm lead-spacing of a TO-92, occupying roughly 70% less PCB area and enabling automated pick-and-place reflow soldering. TO-92 through-hole parts require manual insertion or axial-lead forming, increasing assembly time and cost, while the SOT-23F suits fully automated SMT lines at production volumes above a few hundred units.
When is ZXTN19100CFFTA preferred over a logic-level MOSFET for switching 2 A loads at 24 V?
ZXTN19100CFFTA is preferable when the drive source is a base-current-capable signal above 15 mA and the switching frequency is below 100 kHz, since BJTs tolerate capacitive gate-charge issues that affect some MOSFETs at low gate-drive voltages. At 2 A and 24 V, the BJT's saturation voltage of roughly 200–400 mV is only slightly higher than an equivalent MOSFET's conduction drop, making thermal performance comparable in low-duty-cycle switching applications.
