LCE series
LCE SERIES (1500 WATT) AXIAL TRANSIENT VOLTAGE SUPPRESSORS
(LOW CAPACITANCE DEVICE)
Device for data line interface circuit protection, the LCE series offers low shunt
capacitance to prevent signal degradation. These devices can be used across
transmission lines with signal levels up to 100MHz. For bi-directional applications,
two LCE suppressors are required, connected anti-parallel with respect to each
other, across the circuit to be protected.
FEATURES
G Stand-off voltage range 6.5 to 90 Volts
G Uni-directional
G Glass passivated junction
G Low capacitance: 100pF (max)
G Low zener impedance
G 100% surge tested
MAXIMUM RATING
G Peak Pulse Power (Ppk): 1500 Watts (10 x 1000µs)@25°C
(see diagram on page 3 for wave form)
G 5 watt steady state
G Response time: 1 x 10-12 seconds (theoretical)
G Forward surge rating: 70 Amps, 8.3ms half sine wave, (uni-directional devices only)
G Operating & storage temperature: -55°C to +150°C
MECHANICAL CHARACTERISTICS
G Case: DO-201 AO; Moulded plastic over glass passivated junction
G Terminals: Axial leads, solderable per MIL-STD-202 Method 208
G Solderable leads = 230°C for 10 seconds (1.59mm from case)
G Marking: cathode band, device code, logo
G Weight: 1.5 grammes (approx)
