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.

2. Maximum power dissipation at indicated ambient temperature in free air with no heatsink used.

3. Per SEMI G42-88 specification.

4. ESD1 testing is performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 Ω).

5. ESD2 testing is performed in accordance with the Machine Model (CZAP = 200 pF, RZAP = 0 Ω).

6. 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.
