Notes
1.
Output current rating may be limited by duty cycle, ambient temperature, and heatsinking. Under any set of conditions, do not exceed the
specified current rating or a junction temperature of 150°C.
Maximum power dissipation at indicated ambient temperature in free air with no heatsink used.
Per SEMI G42-88 specification.
ESD1 testing is performed in accordance with the Human Body Model (C
ZAP
= 100 pF, R
ZAP
= 1500
).
ESD2 testing is performed in accordance with the Machine Model (C
ZAP
= 200 pF, R
ZAP
= 0
).
Lead soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
