Characteristic Symbol Value Unit JEDEC Class
Electrostatic Discharge - Human Body Model ESD HBM 4,000 V 3A
Electrostatic Discharge - Machine Model ESD MM ≥ 400 V C
Notes: 6. For a device surface mounted on 15mm X 15mm FR4 PCB with high coverage of single sided 1 oz copper, in still air conditions; the device is measured
when operating in a steady-state condition.
7. Thermal resistance from junction to solder-point (at the end of the collector lead).
8. Refer to JEDEC specification JESD22-A114 and JESD22-A115.
