Additional Details

The TISP4400M3BJR-S is typically housed in a DO-214AA (SMB) package, which allows for efficient heat dissipation. Key specifications include the peak pulse current rating, breakover voltage, and holding current. The device operates by switching to a low-voltage on-state when the voltage exceeds its breakover voltage, thereby clamping the surge voltage and diverting the surge current away from the protected equipment. Its bidirectional protection capability makes it suitable for AC and DC applications. Bourns is a reputable manufacturer known for its high-quality surge protection devices, making the TISP4400M3BJR-S a reliable choice for protecting telecommunications equipment.
