Alpha 27 1N4004 Rectifier Diode-400 PIV

Keep your intercom, entry and access-control systems reliable with the Alpha Communications Alpha 27 1N4004 rectifier diode. Designed for use in Intercom & Entry Accessories, this diode provides essential reverse-voltage protection (400 PIV) while maintaining a low forward voltage drop to reduce heat and improve power efficiency. With a surge overload rating up to 30A peak, it withstands inrush currents and transient events common in security, surveillance and monitoring equipment. Low reverse leakage and a diffused junction construction ensure consistent performance over time, reducing maintenance and downtime for critical door entry and access systems. The lead-free, RoHS-compliant finish meets modern environmental and regulatory requirements for commercial installations. Ideal for technicians and systems integrators, the Alpha 27 1N4004 is a compact, cost-effective component for power supplies, intercom stations, intrusion detection modules and CCTV power circuits. Upgrade or service your intercom and security electronics with a dependable rectifier diode that balances durability and efficiency—order the Alpha 27 today for your next installation or repair.
