TRANSIENT VOLTAGE SUPPRESSOR

FEATURES

Underwriters Laboratory Recognition under UL standard

for safety497B: Isolated Loop Circuit Protection

Low profile package with built-in strain relief for surface

mounted applications

DO-214AA(SMB)

Glass passivated junction

Low incremental surge resistance, excellent clamping

capability

600W peak pulse power capability with a 10/1000µs

waveform, repetition rate (dutycycle): 0.01%

Very fast response time

High temperature soldering guaranteed:

250°C/10 seconds at terminals

MECHANICAL DATA

Case:JEDEC DO-214AAmolded plastic over passivated

junction

Terminals: Solder plated, solderable per MIL-STD-750,

method 2026

Polarity: Foruni-directional types the color band denotes

the cathode, which is postitive with respect to the

anode under normal TVS operation
