FEATURES
♦ Plastic package has Underwriters Laboratory
Flammability Classification 94V-0
♦ Glass passivated junction
♦ 400W peak pulse power capability with a 10/1000µs
waveform, repetition rate
(duty cycle): 0.01%
♦ Excellent clamping capability

♦ Fast response time: typically less
than 1.0ps from 0 Volts to V(BR) for
uni-directional and 5.0ns for bi-directional types
♦ Devices with V(BR)≥10V ID are typically ID less than 1.0µA
♦ High temperature soldering guaranteed:
265°C/10 seconds, 0.375" (9.5mm) lead length,
5lbs. (2.3 kg) tension
MECHANICAL DATA
Case: JEDEC DO-204AL molded plastic body over
passivated junction
Terminals: Axial leads, solderable per MIL-STD-750,
Method 2026
Polarity: For uni-directional types the color band denotes
the cathode, which is posititive with respect to the anode
under normal TVS operation
Mounting Position: Any
Weight: 0.012 ounce, 0.3 gram
DEVICES FOR BIDIRECTIONAL APPLICATIONS
For bi-directional use C or CA suffix for types P4KE7.5 thru types P4KE440 (e.g. P4KE7.5CA, P4KE440CA).
Electrical characteristics apply in both directions.
