IF its a transistor, then if its NPN a diode check measuring from the base +ve to the collector should show roughly 0.6V and likewise to the emitter. Reversing the connection should show no conduction. Likewise, if its a PNP transistor, measuring the from the base -ve to the collector should ALSO show 0.6V and likewise ALSO to the emitter. Reversing this connection should show no conduction. ....and you could always look up the data sheet....
