The UPA1890GR-9JG-E1 is a power MOSFET manufactured by NEC (now Renesas Electronics). Designed for efficient power switching, this MOSFET is likely utilized in DC-DC converters, power management circuits, and load switch applications. A defining characteristic is likely low on-resistance, minimizing power losses. The 'E1' suffix indicates environmental compliance (RoHS) and potentially a specific package variant.

Applications:

• DC-DC Converters
• Power Management Circuits
• Load Switching
• Synchronous Rectification
• Point-of-Load (POL) Converters

Features:

• Low On-Resistance (Rds(on)): Reduces conduction losses for improved efficiency.
• High-Speed Switching: Minimizes switching losses at higher frequencies.
• Logic Level Drive: Allows direct driving from logic circuits, simplifying design.
• Surface Mount Package: Facilitates automated assembly and space-saving designs.
• RoHS Compliant: Meets environmental regulations regarding hazardous substances.

Benefits:

• Improved Energy Efficiency: Lower on-resistance translates to less power dissipation.
• Simplified Circuit Design: Logic-level gate drive eliminates the need for driver circuitry.
• Compact Solution: Surface mount package allows for smaller and denser circuit layouts.
• Enhanced Thermal Performance: Reduced power dissipation leads to lower operating temperatures.
• Environmentally Responsible: RoHS compliance meets environmental regulations.

Technical Specifications:

Typical specifications for this MOSFET series include:

• Drain-Source Voltage (V DSS): Approximately 30V
• Gate-Source Voltage (V GS): Approximately ±20V
• Continuous Drain Current (I D): Several Amperes (dependent on package and cooling conditions)
• On-Resistance (R DS(on)): Very low, in the milliohm range (dependent on V GS and I D)
• Gate Threshold Voltage (V GS(th)): Suitable for logic-level drive
• Total Gate Charge (Q g): Low for fast switching speeds
