Transient Voltage Suppression (TVS) Diodes
Invisible Protection
When no problems exist, Crydom TVS
Diodes are totally invisible to the circuits
they're protecting. But when potentially
damaging transients occur, they provide
high-speed "clamping" to prevent damage
– and then return to their electronically
invisible state.
LCE SERIES (1500 WATT) AXIAL TRANSIENT
VOLTAGE SUPPRESSORS (LOW CAPACI-
TANCE DEVICE)
Designed for data line interface circuit pro-
tection, the LCE series offers low shunt
capacitance to prevent signal degradation.
These devices can be used across trans-
mission lines with signal levels up to 100 MHz.
For bi-directional applications, two LCE
suppressors are required, connected in
anti-parallel with respect to each other,
across the circuit to be protected.
FEATURES
• Glass passivated junction
• Low capacitance: 100 pF (max.)
• Stand-off voltage range: 6.5 -90 V
• Low zener impedance
• Uni-directional
• 100% surge tested

MAXIMUM RATINGS
• Peak pulse power (PPK): 1500 watts
(10 X 1000 µs)
• 5 watt steady state
• Response time: 1 X 10-12 s (theoretical)
• Forward surge rating: 70 A, 8.3 ms half
sine wave (uni-directional devices only)
• Operating and storage temperature:
-55°C to +175°C
MECHANICAL CHARACTERISTICS
• Case: Molded plastic over glass
passivated junction
• Terminals: Axial leads, solderable per
MIL-STD-202 Method 208
• Marking: Cathode band, device code, logo
• Weight: 1.5 grams (approx.)
Note: Suffix “A” denotes 5% tolerance device. No suffix denotes 10% tolerance device. For bi-directional protection, two TVS devices must be used when testing. Test TVS in
avalanche direction. Do not pulse in forward direction. Electrical specifications @ 25°C.
