Over-voltage Protection Thyristor
PXXX0LB
PXXX0LB
Description
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, and TIA-968
(formerly known as FCC Part 68)..
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

Definition
CO Off-state Capacitance — typical capacitance
measured in off state
di/dt Rate of Rise of Current — maximum rated value of
the acceptable rate of rise in current over time
IS Switching Current — maximum current required to
switch to on state
IDRM Leakage Current — maximum peak off-state current
measured at VDRM
IH Holding Current — minimum current required to
maintain on state
IPP Peak Pulse Current — maximum rated peak impulse
current
IT On-state Current — maximum rated continuous
on-state current
ITSM Peak One-cycle Surge Current — maximum rated
one-cycle AC current
VS Switching Voltage — maximum voltage prior to
switching to on state
VDRM
Peak Off-state Voltage — maximum voltage that can
be applied while maintaining off state
VF On-state Forward Voltage — maximum forward
voltage measured at rated on-state current
VT On-state Voltage — maximum voltage measured at
rated on-state current

* For surge ratings, see table below.
Notes:
• All measurements are made at an ambient temperature of 25. IPP applies to -40through +85temperature range.
• Off-state capacitance (CO) is measured at 1 MHz with a 2 V bias and is typical value.
