High Surge Current (D-rated) SIDACtor Device
DO-214AA SIDACtor solid state protection devices with a D surge rating protect
telecommunications equipment such as modems, line cards, fax machines, and other CPE.
These SIDACtor devices withstand simultaneous surges incurred in GR 1089 lightning
tests. (See "First Level Lightning Surge Test" on page 4-5.) Surge ratings are twice that of a
device with a C surge rating. This allows a discrete surface mount version of Littelfuse's
patented "Y" configuration. (US Patent 4,905,119)
SIDACtor 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-A
(formerly known as FCC Part 68).
* For surge ratings, see table below.
** Contact factory for release date.
*** The 2.2 A version cannot be used to meet 4.4 A requirements.
General Notes:
All measurements are made at an ambient temperature of 25 C. I
PP
applies to -40 C through +85 C temperature range.
I
PP
is a repetitive surge rating and is guaranteed for the life of the product.
Listed SIDACtor devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities.
V
DRM
is measured at I
DRM.
V
S
is measured at 100 V/s.
Special voltage (V
S
and V
DRM
) and holding current (I
H
) requirements are available upon request.
Off-state capacitance (C
O
) is measured at 1 MHz with a 2 V bias and is a typical value.
