P6KE480C Equivalent & Substitute Parts

Part Overview

The P6KE480C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for telecom applications. This bidirectional zener diode operates with a reverse standoff voltage of 408V and provides clamping protection at 658V maximum. The device is rated for 900mA peak pulse current and 600W peak pulse power dissipation in a through-hole DO-204AC (DO-15) axial package.

The P6KE480C is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this voltage suppression specification.

• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C to 175°C

Mechanical Parameters (Must Match):

• Package / Case: DO-204AC (DO-15)
• Mounting Type: Through Hole

Acceptable Variations:

• Product Status: Active substitutes are preferred over obsolete parts
• Packaging Format: Cut Tape (CT) or other standard packaging formats are acceptable
• RoHS Compliance: ROHS3 Compliant or RoHS Compliant variants are acceptable
