ZXTN25020DFLTA

Single Bipolar Transistors Overview

The ZXTN25020DFLTA is a single NPN silicon epitaxial planar transistor in an SOT-23 package. It features a collector-emitter voltage (VCEO) of 20V and a continuous collector current (IC) of 2A. The device achieves low saturation voltage, typically 60mV at IC=1A with IB=100mA. Electrical characteristics include a DC current gain (hFE) ranging from 300 to 900 at IC=10mA, and a transition frequency (fT) of 215MHz at IC=50mA. Power dissipation is rated at 350mW, with an operating temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the complete part number includes the 'TA' suffix for reel packaging containing 3,000 units per carrier. Confirm compliance with EU RoHS directives and Halogen/Antimony-free requirements if specified by project standards. Ensure the ordering code matches the exact marking '1A1' on the SOT-23 component body.

Single Bipolar Transistors Selection Notes

Select this component when a low VCE(sat) is required for NPN switching applications up to 2A. The SOT-23 package limits thermal performance compared to larger packages; verify PCB copper area meets the 25mm x 25mm FR4 standard for accurate derating calculations. Consider the 20V rating against potential transient spikes in the target circuit.

Single Bipolar Transistors Part Context

This device belongs to the ZXTN250 series of low saturation transistors manufactured by Diodes Incorporated. It utilizes a specific epitaxial planar process designed to minimize voltage drop during conduction. The product is intended for general-purpose switching and amplification tasks where space constraints favor the compact SOT-23 footprint.

Single Bipolar Transistors Replacement Considerations

Consult official Diodes Incorporated documentation for qualified substitutes. Verify pinout compatibility and electrical parameters such as VCEO, IC, and VCE(sat) before substituting.
