PXXXXSX SERIES
Thyristor Surge Suppressors (TSS) Data Sheet
Description
DO-214AA Thyristor solid state protection thyristor protect
telecommunications equipment such as modems, line cards,
fax machines, and other CPE.
P Series devices are used to enable equipment to meet
various regulatory requirements including GR 1089, ITU
K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968
(formerly known as FCC Part 68).
Features
Compared to surge suppression using other technologies, P Series devices offer absolute surge protection
regardless of the surge current available and the rate of applied voltage (dv/dt). P Series devices:
■ Cannot be damaged by voltage
■ Eliminate hysteresis and heat dissipation typically found with clamping devices
■ Eliminate voltage overshoot caused by fast-rising transients
■ Are non-degenerative
■ Will not fatigue
■ Have low capacitance, making them ideal for high-speed transmission equipment
■ Meets MSL level 1, per J-STD-020
■ Safety certification: UL: E244458
