hi joe thanks for your response.it has 3 pins on one side and on
thicker pin like a small heatsink looks like this

i'd appreciate any help on where to get another or an equivalant.i've
looked through shed loads of smt code books online cant find same
code.i've tried contacting kenwood????
thankyou-
It could be a transistor as the other poster mentioned, but it could
also be a voltage regulator IC. Your best bet would be to obtain a
schematic and/or parts location diagram for your radio to help ID the
component. Then your next stop would be Digi-Key or Mouser to look for
a
replacement.
Also, try to determine what caused the part to fail before installing
the new one so it doesn't meet the same fate.

========================================
The OP did not mention the handheld radio model ,other than it is from
Kenwood. *An instruction manual with circuit diagramme(s) of the
relevant radio can highly likely be found at : *www.mods.dk

hi,
thanks to all responders .there are three on the same board.the model
is a th-26 handheld 2m.i've checked all the surrounding resistors and
nearby passives .i think its a power supply problem.i dont want to
power it up yet until i find out what this part doesi dont want to take
another one of these ants lol out and check it out of circuit.smt is not
my thing.i've searched for a free schematic so if anyone out there's got
the schematic that'll be great .i'll take on board what you guys have
said many thanks for taking the time.

More than likely your talking about a transistor maybe a mosfet
The center lead is the collector or drain.
Look for the same numbers on other parts
and measure the forward to back ratio. To determine the kind of
semi it is. should be quite ez. Mostly they using transistors like
this for switching or buffers
so I don't think it could be a darlington.
It's either a npn or pnp.
less likely a FET n channel or p channel
It could still be a zener or a dual diode
Zeners they connect the 2 leads together
And a dual diode will have the same reading on each junction.
