MRF101AN

Overview

The MRF101AN is an N-channel enhancement-mode lateral MOSFET (LDMOS) transistor designed for RF power applications up to 250 MHz. It operates at a drain-source voltage of 50 Vdc and delivers continuous wave output power ranging from 104 W to 130 W across frequencies between 13.56 MHz and 87.5 MHz. The device features a TO-220-3 package with Pin 1 as Gate, Pin 2 as Source, and Pin 3 as Drain. It includes integrated ESD protection and is characterized for operation from 30 V to 50 V.

Feature Summary

• Mirror pinout versions available to simplify push-pull configurations
• Integrated ESD protection with extended negative gate-source voltage range
• Suitable for linear applications and Class C operation
• Extremely rugged design capable of withstanding high load mismatch

Applications

• Industrial, scientific, and medical (ISM) equipment such as plasma etching and laser generation
• HF and VHF communications systems
• Radio and VHF TV broadcast transmitters
• MRI and other medical imaging applications

Procurement Notes

Verify the specific ordering suffix and package variant against the official datasheet before procurement. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing process. Ensure that the supply chain source provides valid traceability documentation. Check for any end-of-life notifications or recommended replacement parts if long-term availability is required for the project lifecycle.

Selection Notes

Select the MRF101AN when designing broadband RF power amplifiers requiring high ruggedness and performance up to 250 MHz. Consider the mirror pinout configuration if utilizing a two-up push-pull topology to simplify layout. Evaluate thermal management requirements based on the specified junction-to-case thermal resistance. Ensure the application voltage does not exceed the maximum rated drain-source voltage of 133 V.
