This listing is a pair of On Semiconductor MJL1302DG MJL3281DG high power bipolar transistors for power amplifier application.
These transistors have linear current gain characteristics across a wide range of operating current and are thus exceptionally suitable for all kinds( that is, either class A or class AB) of power amplifier application.
These power transistors have thermal sensing within the packing for best thermal protection ( external circuitry needed)
