Product details
Overview
MRF6VP41KHR5 from NXP Semiconductors (formerly Freescale) is a 1000 W peak, 50 V lateral N-channel RF power MOSFET designed for broadband push-pull amplifier stages in industrial, scientific, and medical (ISM) systems operating up to 500 MHz. It delivers 20 dB power gain and 64% drain efficiency at 450 MHz under pulsed conditions (100 μs, 20% duty cycle), with 10:1 VSWR tolerance and integrated ESD protection.
For engineers reviewing the MRF6VP41KHR5 datasheet, MRF6VP41KHR5 pinout, MRF6VP41KHR5 application, or MRF6VP41KHR5 equivalent, this device requires attention to gate bias stability, thermal management at TC = 150°C, impedance matching networks per frequency band (352.2/450/500 MHz), and push-pull layout constraints - especially given its dual-gate/dual-drain configuration and 0.03 °C/W pulsed thermal impedance.
Technical Context
This device is a matched pair of enhancement-mode LDMOS transistors in a single NI-1230 package, configured for balanced push-pull operation. Its series-equivalent large-signal impedance parameters are characterized at 352.2 MHz (CW), 450 MHz (pulsed), and 500 MHz (pulsed), enabling precise input/output network synthesis using Zsource = 0.5 + j6.5 Ω (352.2 MHz) and Zload = 1.58 + j1.22 Ω (450 MHz).
It operates with VGS(th) = 1.68 V (typ), supports gate-source voltage range of –6 V to +10 V, and withstands 110 VDS breakdown. The device is qualified for continuous-wave operation up to 50 VDD with adequate heatsinking, and features integrated ESD protection meeting HBM Class 2 (2000 V), MM Class A (125 V), and CDM Class IV (2000 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MRFE6VP61KHR5 | Higher Pout (1200 W peak), same 50 V, 10–500 MHz range; improved gain flatness and lower Crss (2.8 pF vs. 3.3 pF). | Better suited for multi-octave broadband systems requiring tighter gain ripple; higher cost and larger thermal footprint. | Select when >1000 W peak is needed or when system-level gain flatness over 10–500 MHz is critical. |
| CGHV1F025S | GaN-on-SiC process; 250 W CW at 1.3 GHz; not pin-compatible; higher gain (22 dB), higher efficiency (75%), but narrower bandwidth (1.2–1.4 GHz). | Targeted at L/S-band radar, not ISM bands; requires redesigned matching networks and gate bias circuitry. | Choose only for new designs targeting >1 GHz operation where GaN's high-frequency advantage outweighs redesign effort. |
Compared with MRFE6VP61KHR5, MRF6VP41KHR5 offers lower cost and proven thermal reliability in legacy ISM systems; compared with CGHV1F025S, it provides broader low-VHF/UHF coverage and mature support infrastructure, though at lower frequency ceiling and efficiency.

FAQ
What is the maximum continuous-wave (CW) output power rating for the MRF6VP41KHR5?
The MRF6VP41KHR5 is rated for 1000 W CW output at 352.2 MHz with 67% drain efficiency, VDD = 50 Vdc, and IDQ = 150 mA. Its total device dissipation is 1333 W at TC = 25°C under CW conditions, as specified in Rev. 6 (2012) of the datasheet. Operation above 352.2 MHz in CW mode requires derating based on thermal impedance curves and measured efficiency data.
Does the MRF6VP41KHR5 support single-ended operation, or is it strictly for push-pull configurations?
The MRF6VP41KHR5 is explicitly designed for push-pull operation, as confirmed by its dual-gate/dual-drain pinout, characterization data (e.g., Zsource/Zload measured "gate-to-gate" and "drain-to-drain"), and feature list stating "Designed for Push–Pull Operation." Single-ended use is not supported - attempting it risks imbalance, instability, and thermal runaway due to internal device coupling and unmatched parasitics.
What are the recommended gate bias conditions for Class C operation of the MRF6VP41KHR5?
For Class C operation, the MRF6VP41KHR5 leverages its extended negative gate-source voltage range (–6 V). Typical quiescent gate voltage VGS(Q) is 1.5–3.5 Vdc at IDQ = 150 mA and VDD = 50 Vdc. To achieve deep Class C, apply a negative DC offset (e.g., –1.5 to –3.0 V) superimposed on the RF drive, ensuring gate voltage never exceeds +10 V or drops below –6 V. Bias network must suppress oscillation and maintain stability across 10–500 MHz.
How does the thermal performance of the MRF6VP41KHR5 differ between pulsed and CW operation?
Pulsed operation (e.g., 100 μs, 20% duty cycle at 450 MHz) yields ZθJC = 0.03 °C/W, enabling rapid junction temperature estimation. CW operation at 352.2 MHz gives RθJC = 0.15 °C/W - five times higher - demanding significantly more aggressive heatsinking. Both values assume case temperature monitoring at the package base; actual thermal design must account for mounting interface resistance and ambient airflow per AN1955 guidelines.
Is the MRF6VP41KHR5 RoHS-compliant and lead-free?
Yes, the MRF6VP41KHR5 is RoHS-compliant and lead-free, consistent with NXP's product environmental compliance policy. The NI-1230 package uses lead-free metallization and complies with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements. Full compliance documentation, including substance declarations and test reports, is available via NXP's official product page and environmental portal.
