N‑MOSFET transistor EB44475428 200V 17.8A

The N‑MOSFET transistor EB44475428 200V 17.8A is an N‑channel power MOSFET specified for a 200 V drain‑source voltage and a continuous current capability of 17.8 A. It is engineered for switching and power management tasks in electronic circuits, providing low on‑resistance switching and reliable thermal handling when operated within its rated limits. Typical applications include power supplies, motor control stages, and load switching elements in DC systems.

Advantages

This N‑channel MOSFET offers a balance of voltage rating and current capacity suitable for medium‑power designs, with low conduction losses under proper gate drive conditions. Its robust voltage rating makes it suitable for circuits requiring 200 V blocking capability, while the continuous current rating supports sustained loads when mounted on appropriate thermal management structures. The device's switching characteristics enable efficient on/off control in PWM and high‑frequency applications when used within specified limits.

Suitable for

• Switching stages in DC‑DC converters and power supplies
• Motor driver outputs for small to medium motors
• Load switching and reverse current protection in battery systems
• General-purpose power switching in industrial and consumer electronics

Key specifications

• Device type: N‑channel MOSFET
• Drain‑source voltage (Vds): 200 V
• Continuous drain current: 17.8 A
• Intended use: switching and power management
• Thermal considerations: requires appropriate heat sinking or PCB thermal design for sustained currents

How to use

Operate the MOSFET with a gate drive voltage appropriate for full enhancement while ensuring gate‑source voltage limits are not exceeded. Place the device on a PCB with sufficient copper area or attach a heat sink to manage dissipation during continuous operation near the current rating. Observe safe operating area (SOA) and thermal limits: avoid sustained operation at maximum ratings without adequate cooling. Implement gate resistors and, where required, snubbers or transient protection to limit voltage spikes during switching.

Usage recommendations

For reliable performance, design the circuit to keep junction temperature below the specified maximum by using thermal vias, heatsinking, and conservative duty cycles. Use appropriate gate drivers to achieve fast but controlled switching transitions, and include transient suppression measures such as TVS diodes or RC snubbers when operating in inductive environments.
