Product Description
Littelfuse SP721ABTG is a 6-element bi-directional transient voltage suppression (TVS) diode array designed for electrostatic discharge (ESD) and over-voltage protection in sensitive electronic input circuits. This 8-pin SOIC surface-mount device integrates SCR/Diode bipolar structures offering reliable safeguarding of up to six external signal or bus lines.
The device features two protection SCR/Diode structures per input, activating clamping to positive or negative voltage rails upon transient pulse detection. Triggering occurs at thresholds approximately one diode voltage drop above or below the supply lines, enabling rapid response to transient events.
Designed for robust industrial use, it operates over a temperature range from -40°C to 105°C, ensuring reliable performance in demanding environments. The package dimension is a compact 5 mm length, 4 mm width, and 1.5 mm height, facilitating its integration into dense circuit layouts.
Key technical specifications include a maximum reverse stand-off voltage of 30 V, a test current rating of 1 A, and peak pulse current capacity of 2 A. The maximum reverse leakage current is minimal at 20 μA, assuring low power loss during normal circuit operation.
This Littelfuse TVS Diode Array is primarily utilized in electronic protection applications within industrial, automotive, and consumer electronics manufacturing, providing high level ESD and surge protection to improve circuit reliability and longevity.
Features 6-element SCR/Diode array for multi-line protection. Bi-directional operation suitable for various signal directions. Compact SOIC 8-pin surface mount design. Wide operating temperature range from -40°C to 105°C.
High peak pulse current of 2 amperes for transient events. Low leakage current ensuring efficient operation. Fast response triggering above and below supply voltage rails. Suitable for use in harsh industrial and electronic environments.
