Product Overview
MRF101AN is NXP rugged LDMOS RF power transistor. It outputs 100W CW power up to 250MHz under 50V supply, with built-in ESD protection to withstand 65:1 VSWR mismatch. TO-220 through-hole package simplifies heat dissipation, suitable for ISM, broadcast, radio and industrial RF equipment.
Core Advantages
Extreme Ruggedness and VSWR Protection
Supports over 65:1 VSWR full-power operation without extra isolation circuits.
High Gain and Efficiency
20~26dB power gain, drain efficiency up to 75%, lowers drive power and cooling cost.
Standard Plastic TO-220 Package
Source-connected tab for direct heatsink mounting, reduces assembly cost vs ceramic packaging.
Wide Frequency Coverage
Covers 1.8MHz~250MHz HF/VHF band for multi-scene RF amplifier design.

Frequently Asked Questions
Q1: Difference between MRF101AN and MRF101BN?
A: Pinout mirror design. MRF101AN:1=Gate,2=Source,3=Drain; BN swaps Gate/Drain pins, convenient for push-pull amplifier layout.
Q2: Why tab connects to source pin?
A: Shortest RF ground path and lowest thermal resistance, no isolation pad needed for heat sink.
Q3: How does built-in ESD protection work?
A: On-chip bidirectional diodes on gate-source block static surge, avoid gate breakdown during assembly & operation.
Q4: Can it cover full HF-VHF wideband?
A: Yes. Narrow band tuning gets max efficiency; transmission line transformers support 1.8~250MHz broadband circuits.
Q5: Is this transistor industrial temperature rated?
A: Yes, junction temp range -40℃~150℃, fits industrial outdoor & high-power continuous working devices.
Q6: Do you supply genuine original NXP MRF101AN?
A: All stock are factory original NXP components, with batch trace code and full quality warranty.
Q7: What heatsink size is recommended for 100W full power?
A: Need heatsink thermal resistance ≤0.5℃/W with forced air cooling for continuous 100W CW output.
