Overview of CEP7030L
- Type: N-Channel Logic Level Enhancement Mode Field Effect Transistor (FET)
- Manufacturer: Chino-Excel Technology
Key Specifications
- Drain-Source Voltage (VDS): Typically around 30V.
- Continuous Drain Current (ID): Can handle currents up to approximately 70A.
- Gate-Source Voltage (VGS): Logic level, which means it can be driven directly by low-voltage digital logic circuits such as microcontrollers (e.g., 5V or 3.3V logic levels).
- Low On-Resistance (RDS(on)): A low RDS(on) reduces the power loss and heat generated when the transistor is conducting.
- Enhancement Mode: Requires a positive voltage on the gate relative to the source to turn on, making it energy-efficient when switching.
