Feature Benefit Bullets

Package Body Material: PLASTIC/EPOXY

The use of plastic/epoxy material makes the transistor lightweight and durable, ensuring a longer lifespan for the product.

Polarity or Channel Type: N-CHANNEL

N-channel transistors typically have lower ON-resistance and higher electron mobility, making them more efficient for switching applications.

Configuration: SEPARATE, 2 ELEMENTS WITH BUILT-IN DIODE

The separate configuration with built-in diode allows for more versatile usage and better performance in certain circuit applications.

Transistor Application: SWITCHING

Designed specifically for switching applications, this transistor can efficiently control and regulate the flow of current in electronic circuits.

Maximum Drain-Source On Resistance: 0.1 ohm

The low on-resistance of 0.1 ohm ensures minimal power loss and higher efficiency during operation, making it an ideal choice for switching applications.
