Product Overview

The SP0503BAHTG is a 4-pin 3-channel 8V surface-mount Unidirectional TVS Diode Array with matte tin (Sn) plated leads. It is used to meet the International Electrotechnical Compatibility. The SPA® diode can help protect sensitive digital or analog input circuits on data, signal or control lines with voltage levels up to 5VDC. The monolithic silicon array is comprised of specially designed structures for transient voltage suppression (TVS). The size and shape of this structure has been tailored for transient protection. The low capacitance and clamp voltage are ideal for high speed signal line protection.
  • <1ns Fast response time
  • 30pF Typical low input capacitance
  • -55 to 125°C Operating temperature range
