NOTES: 1. Each of the two active output transistors can dissipate 60W.
2. Unless otherwise noted: T_C = 25°C, Vcc = 12Vdc.
3. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to
achieve high MTTF. For guidance, refer to the heatsink data sheet.
4. Guaranteed but not tested.
5. Derate to 70V below T_C = +25°C.
CAUTION
The SA51 is constructed from MOSFET transistors. ESD handling procedures must be observed.
The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or
subject to temperatures in excess of 850°C to avoid generating toxic fumes.
WARNING—AMPLIFIER PROTECTION
The SA51 contains an internal logic chip that turns on and
turns off output MOSFET drivers at a certain sequence. Noise
or oscillation caused by external wiring inductance, lack of
proper power supply bypass capacitors, ground, supply, and
local internal loops may be fed back to this logic chip and cause
it to turn on one or more MOSFET drivers at the wrong time,
thus destroying the SA51. A well laid out PC board with low
impedance copper ground plane is necessary for the SA51
to function properly. The Apex EK-SA51 evaluation board
is recommended for fast and easy breadboarding of circuits
using the SA51.
