Alpha Communications 027 Rectifier Diode 400 Piv

Product Description

The ALPHA COMMUNICATIONS 027 is a rectifier diode rated at 400 PIV (peak inverse voltage), equivalent in specification to the common 1N4004 general-purpose silicon rectifier. Rectifier diodes convert alternating current to direct current and are used as protective or power-conditioning components in low-voltage electronic circuits. This part is sold individually and is intended for use by electronics-competent technicians performing component-level repair or replacement on intercom and access control equipment.

This diode is suited for intercom accessory applications where a standard 400 PIV rectifier is required. Typical uses include power supply circuits, reverse-polarity protection, and signal rectification within intercom panel assemblies. The part is sold as a single unit and is appropriate for bench technicians, intercom installers, and service professionals working on low-voltage door and communication systems.

Key Features

• 400 PIV rating for standard general-purpose rectification tasks
• Equivalent specification to the 1N4004 silicon rectifier diode
• Sold individually for precise replacement quantities
• Compact through-hole package suitable for PCB-level repair

Compatibility

Designed as an OEM-style replacement rectifier diode for ALPHA COMMUNICATIONS intercom accessory assemblies requiring a 400 PIV general-purpose silicon rectifier.

Installation Notes

Installation should be performed by a qualified technician familiar with low-voltage electronic component work. De-energize and fully discharge the circuit board before removing or installing any diode. Observe correct polarity orientation before soldering - reversing the diode will prevent proper rectification and may damage downstream components. Follow applicable low-voltage wiring codes and the equipment manufacturer's service documentation.
