Features, Applications

V(BR) Unidirectional to 540V V(BR) Bidirectional to 440V Peak Pulse Power 400W

Plastic package has Underwriters Laboratory Flammability Classification 94V-0 Glass passivated junction 400W peak pulse power capabililty on 10/1000s waveform, repetition rate (duty cycle): 0.01% Excellent clamping capability Low incremental surge resistance Very fast response time

Case: JEDEC DO-204AL molded plastic body over passivated junction Terminals: Axial leads, solderable per MIL-STD-750, Method 2026 High temperature soldering guaranteed: 265C/10 seconds, 0.375" (9.5mm) lead length, 5lbs. (2.3 kg) tension Polarity: For unidirectional types the color band denotes the cathode, which is positive with respect to the anode under normal TVS operation Mounting Position: Any Weight: 0.012 oz., 0.3 g Packaging Codes Options (Antistatic): 1K per Bulk box, 5.5K per 13" paper Reel (52mm horiz. tape), 3K per horiz. tape & Ammo box, 30K/carton

For bi-directional, use or CA suffix for types P4KE6.8 thru types P4KE440 (e.g. P4KE6.8C, P4KE440CA). Electrical characteristics apply in both directions.

Parameter Peak power dissipation with a 10/1000s waveform Peak pulse current wih 10/1000s waveform(1) Steady state power dissipation = 75C, lead lengths 0.375" (9.5mm)(2) Peak forward surge current, 8.3ms single half sine-wave unidirectional only (3) Maximum instantaneous forward voltage at 25A for unidirectional only (4) Typical thermal resistance junction-to-lead

Typ. thermal resistance junction-to-ambient, LLead = 10mm Operating junction and storage temperature range
