N-P-N Planar Transistors
For High·Voltage Switching and
• For operation at junction
lomperature up to 2000 C
• Planar construction for
low noise and low leakage
These devices are available with either 1%·
inch leads fTO-5 package) or %-inch leads
(TO·39 package). The longer-lead versions are
specified by suffix "L" after the type num-
ber; the shorter-lead versions are spacified by
suffix "s" after the type number.
RCA·40346, ·40346V1, ·40346V2, ·40412, ·40412V1, and
-40412V2 are silicon n·p-n transistors having high breakdown
voltages, high frequency·response capability, and fast switch·
These transistors are intended for a wide variety of low· and
medium·power, high·voltage applications. Types 40346,
40346V1, and 40346V2 are especially useful in such de·
vices as neon indicator and NIXIE* driver circuits and
in differential and operational amplifiers. Types 40412,
40412V1, and 40412V2 are especially suited for class·A
acldc audio·amplifier service.
Types 40346 and 40412 are supplied in a JEDEC TO·
39 (S) or TO-5 (L) package; types 40346V1 and 40412V1,
with a factory·attached heat radiator for greater free·air
dissipation,capability; and types 40346V2 and 40412V2 are
supplied with an attached flange for increased power dissi·
pation and mounting convenience.
