cheap genuine RD15HVF1 do'nt exist

                on eBay or UTsource (above)   its all fake UT source did refund
 left is the genuine a bit smaller then the TO220 IRF stamped as RD15HVF1
The original RD15xx types have a small Gate to source C ca 80pF and the source at pin 2
The fake have high gate - C  this one 800-900pF  and its source is pin 3 like all IRF -types
The IRF510 has the lowest gate capacity of about 400pF the best of the rest

Misubishi's   RD15HVF1 is an  UNIQUE  VHF power FET.
With its Source at pin2 = cooling flange,  the only right  place of course
No other manufacturers deliver comparable divices.
It must be hard to produce. The eBay offered types are all fake cheap IRF5xx imitations in fact fraude.
The RD15xxx is relative expensive for a small FET  5-7€  from vendors that will easy take 50$ or more for shipment.
Not sold by  Farnell Digi Key Reicheld  and Mouser
In RF high power FET segment there is plenty of choice  but   it's crisis in HF VHF  medium power land. The classic bipolar RF medium power transistors are no longer produced.

                                          this is how a  real RD15HVF1 is measured
