Product Overview

ITT WEP170 delivers general purpose line rectification rated for 1000V peak reverse voltage and 2.5A average forward current. Encapsulated in a DO-41 axial outline with a printed cathode band, it serves as a drop-in replacement across vintage linear supplies, radio restorations, and legacy control circuits.

Key Features

• 1000V peak inverse voltage (PIV / VRRM) rating
• 2.5A average rectified forward current
• DO-41 axial lead package with clear cathode polarity band
• Direct cross reference to HEP170, ECG125, and NTE125 rectifiers
• Solid-state silicon junction construction for reliable line rectification

Applications

• Rebuilding vintage linear DC power supply stages and tube amplifier bias supplies
• Replacing damaged secondary bridge rectifiers on legacy industrial control boards
• Constructing hobbyist bench power supplies and high-voltage DC multiplier circuits

Frequently Asked Questions

What are the direct cross-reference part numbers for the WEP170?

The WEP170 cross-references directly to industry standard replacement rectifiers including ECG125, HEP170, NTE125, and R170-B.

How is polarity identified on this diode?

The printed band around the black cylindrical body marks the cathode terminal.

What package footprint does this diode use for board layout?

It uses a standard DO-41 axial outline fitting standard through-hole PCB lead spacings or point-to-point terminal strips. The price-break table on this page shows the price per piece at every step.

Built for the quiet, unglamorous job of turning wall AC into clean DC, this NOS rectifier drops straight onto the bench ready to put a vintage power supply back to work.
