SP4020 and SP4021 Series TVS Diode Arrays

Littelfuse's single-channel TVS diode arrays provide higher power handling and lower capacitance

Image of Littelfuse's SP4020 and SP4021 Series TVS Diode ArraysThe Littelfuse SP4020 and SP4021 series TVS diode arrays can safely provide up to 30 A (SP4020)/25 A (SP4021) protection against lightning induced surges and up to 750 W (SP4020)/600 W (SP4021) of power handling capability. This revolutionary design offers 2x the power handling capability of alternative solutions, and yields a 16% improvement in low loading capacitance (2.5 pF TYP) than competitive products. It is ideal for protecting telecommunications interfaces and other high-speed data without sacrificing signal integrity.

  • Superb surge protection
    • Peak pulse power: 750 W (SP4020); 600 W (SP4021)
    • Lightning, IEC61000-4-5: 30 A (SP4020), 25 A (SP4021)
  • Low capacitance of 2.5 pF (TYP)
  • Enhanced ESD capability
  • ESD, IEC61000-4-2, ±30 kV contact
  • Low dynamic resistance
    • RDYN is 0.7 Ω for SP4020
    • RDYN is 0.52 Ω for SP4021
  • Compared to similar market solutions, the SP4020 and SP4021 series provide remarkably more overhead to electrical threats defined by regulatory standards
    • 2x higher power handling capability for the SP4020
    • 1.5x higher power handling capability for the SP4021
  • 16% lower capacitance than other solutions helps to preserve signal integrity and minimize data loss while offering a more robust device against electrical threats
  • Enhanced ESD protection far exceeds the highest level of the IEC61000-4-2 standard (±8 kV), providing maximum reliability for equipment during installation and servicing
  • Provides low clamping voltages for sensitive chipsets, protecting them from catastrophic failure and maximizing system reliability
