Help with Equivalents

[DieterD]

Hi all,
My sone has two Maplin 150 watt Mosfet amps that we would like to copy, problem is my local supplyer does not stock the following transistors:
2SD872A, 2SD756, 2SD716,

I am not a boffin, but they seem to be high voltage TO92, any one want to suggest alternatives. Unfortunately I only have the stuffing guide and no schematic, but it appears to be similar to a Mosfet design by Penfold.

Any help will be appreciated

2SD872 (The A-version is unknow to me): S-L, 500/400V, 5A, 40W, -/3µs
Possible replacements:
MJE13070
2SC2535
2SC2827
2SC3830

2SD756: Uni, 120V, 0,05A, 0,75W, 350MHz
Possible replacements:
2SC2632
2SC3245A
2SC3248
2SC3800

2SD716: HiFi-NF-E, 100V, 6A, 60W, 12MHz
Possible replacements:
BD245C
BDV95
2SC2681
2SD895...96

None of these transistors are mosfets though.

Hi

According to On semi the 2SD872 is equivalent to the MJE3055T. One just needs to be careful of the Vce.

I cant find a direct replacement for the other two devices. At least not in any references I normally use.
Your suggestion that they may be high voltage TO92 seems to be correct. According to their data sheet they are rated: Vce = 120V.
