With peak pulse power of 500 W and 600 W, respectively, SP4044 and SP4045 Series are integrated with additional zener diode to protect each I/O pin. Units can handle minimum of ±30 kV ESD, and can safely absorb up to 24 A of lightning-induced surges while presenting only 1.5 pF per I/O-to-Ground connection. Very low dynamic resistance of 0.22 Ω for SP4044 and 0.3 Ω for SP4045 produces low clamping voltages, allowing devices to protect modern/small geometry chipsets against ESD transients.
