P4802AAL Description

Short technical summary and product information.

The P4802AAL is a two-chip SIDACtor thyristor from Littelfuse, designed to protect baseband equipment from damaging overvoltage transients. It provides robust peak surge current capability enabling voice through DS-1 equipment to comply with various global regulatory standards such as TIA-968-A/B, ITU K.20/21, GR 1089, and IEC 61000-4-5.

 

Key electrical characteristics include a repetitive peak off-state voltage (VDRM) of 220V to 300V at IDRM=5µA, and a switching voltage (VS) of 440V to 600V at 100V/µs. The maximum on-state voltage (VT) is 4V at IT=2.2A. Holding current (IH) is 150mA minimum, switching current (IS) is 800mA maximum, and on-state current (IT) is 2.2A maximum. Capacitance is 20pF (pins 1-2) and 35pF (pins 3-2) at 1MHz with 2V bias.

 

The device is housed in a 3-SIP (TO-220 Modified) through-hole package. It features low voltage overshoot, low on-state voltage, and does not degrade surge capability after multiple surge events within limits. The part fails short circuit when surged in excess of ratings, ensuring fail-safe operation. It is RoHS compliant and Pb-free E3.
