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. CAUTION NOTES: 1. Each of the two active output transistors can dissipate 36W. This is an output FET rating only; normal operation at worst case conditions and maximum duty cycle only causes 19 watts internal heat generation in each active output FET. Use 40 watts maximum to size heatsink. 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 linearly to 70V at – 40°C from T C = +25°C. WARNING—AMPLIFIER PROTECTION The SA50CE contains an internal logic chip that turns on and turns off output MOSFET drivers at a certain sequence. Noises or oscillation caused by external wiring inductance, lack of proper power supply bypass capacitors, ground, sup- ply 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 SA50CE. A well laid out PC board with low impedance copper ground plane and excellent bypassing is necessary for the SA50CE to function properly. A low ESR high frequency bypass capacitor, such as a 0.1 µf 100V X7R ceramic, or better, should be mounted as close to the Vs and ground pins as possible to avoid radiation of high frequency transients on the power supply wiring. The Apex EK-SA50CE evaluation board is recommended for fast and easy breadboarding of circuits using the SA50CE. |
