DESCRIPTION
The SMTPBxx series has been designedto protect
telecommunication equipment against lightning
and transient induced by AC power lines.
FEATURES
BIDIRECTIONAL CROWBAR PROTECTION.
BREAKDOWN VOLTAGE RANGE:
From 62 V To 270 V.
HOLDING CURRENT: IH = 150 mA min
REPETITIVE PEAK PULSE CURRENT :
IPP = 100 A, 10/1000 µs.
BENEFITS
NO AGEING AND NO NOISE
IF DESTROYED, THE SMTPB FALLS INTO
SHORT CIRCUIT, STILL ENSURING
