NPN Transistor EB587696124 30V 0.1A SOT‑143

NPN transistor EB587696124 30V 0.1A SOT‑143 is a surface‑mount small‑signal transistor designed for compact electronic circuits. The transistor supports a maximum collector‑emitter voltage of 30 V and a maximum collector current of 0.1 A. Packaged in SOT‑143, it is intended for general‑purpose switching and low‑power amplification where board space and automated assembly are important.

Advantages

The SOT‑143 surface‑mount package allows for space‑saving PCB layouts and compatibility with automated pick‑and‑place assembly. The device’s 30 V voltage rating and 0.1 A current capability suit many low‑power switching and signal amplification tasks. As a general‑purpose NPN transistor, it offers straightforward integration into standard biasing and driver circuits and is suitable for use in dense electronic assemblies.

Suitable for

• Low‑power switching in compact consumer electronics
• Small‑signal amplification in audio, sensor, or communication circuits
• Surface‑mount designs requiring automated assembly
• Prototyping and production of space‑constrained PCBs

Key specifications

• Transistor type: NPN small‑signal
• Maximum collector‑emitter voltage (Vce): 30 V
• Maximum collector current (Ic): 0.1 A
• Package: SOT‑143 surface‑mount
• Application class: general‑purpose switching and small‑signal amplification

How to use

Install the SOT‑143 device on the PCB following the recommended footprint and soldering profile for surface‑mount components. Use standard biasing networks and base resistors appropriate for NPN transistors to set operating point and limit base current. Observe the maximum collector‑emitter voltage of 30 V and keep collector current below 0.1 A during operation. For switching applications, ensure the transistor is driven into saturation or cutoff with suitable base drive; for amplification, operate it within its linear region with correct biasing and bypassing to achieve desired gain and stability.

Usage recommendations

Avoid exceeding the specified voltage and current limits and provide adequate thermal relief on the PCB. Verify soldering temperature profiles compatible with SOT‑143 and use proper ESD handling to protect the transistor during assembly and testing.
