1500 Watt Axial Leaded Transient Voltage Suppressors
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
• Stand-off voltage range 6.5 to 90 Volts
• Uni-directional
• Glass passivated junction
• Low capacitance: 100pF (max)
• Low zener impedance
• 100% surge tested
MAXIMUM RATING
• Peak Pulse Power (Ppk): 1500 Watts (10 x 1000µs)@25°C
(see diagram on page 3 for wave form)
• 5 watt steady state
• Response time: 1 x 10-12 seconds (theoretical)
• Forward surge rating: 70 Amps, 8.3ms half sine wave, (uni-
directional devices only)
• Operating & storage temperature: -55°C to +150°C
MECHANICAL CHARACTERISTICS
• Case: DO-201AD; Molded plastic over glass
passivated junction
• Terminals: Axial leads, solderable per MIL-STD-202
Method 208
• Solderable leads = 230°C for 10 seconds (1.59mm from case)
• Marking: cathode band, device code, logo
• Weight: 1.5 grammes (approx)
Agency Approvals: Recognized under the Components
Program of Underwriters Laboratories.
