RCA3054 and RCA3055 are silicon n-p-n transistors intended
for a wide variety of high-current applications_ The home-
taxial-base construction of these devices renders them highly
resistant to second breakdown over a wide range of oper-
The VERSAWATT case has a proven thermal-cycle capability_
This capability is assured by real-time quality controls in our
manufacturing locations_ The RCA3054 and RCA3055 are
supplied in the JEDEC TO-220AB straight-lead version of the
package. They are also available on special order in a variety
of lead-form configurations. Two popular v~riations have leads
formed to fit TO-66 sockets (specify formed lead No. 6201)
or printed-circuit boards (specify formed lead No_ 6207).
Detailed information on these and other VERSAWATT
outlines is contained in "RCA's Lineup of Power Transistors"
