5399 – Silicon Rectifier LRM Diode

LRM 5399 – Silicon Rectifier Diode (1.5A, 1000V, DO-15)

The LRM 5399 Silicon Rectifier Diode is a high-voltage, general-purpose rectifier designed for reliable AC-to-DC conversion in a wide range of electronic applications. Built to handle a maximum forward current of 1.5A and a peak repetitive reverse voltage of 1000V, this diode is engineered to perform under demanding electrical conditions.

Packaged in the compact and robust DO-15 (DO-204AC) axial-lead through-hole format, the LRM 5399 is easy to mount on standard PCBs, breadboards, and prototype circuits. The color band on the body clearly identifies the cathode end, reducing the chance of installation error.

Key Features:

• Maximum Forward Current: 1.5A
• Peak Repetitive Reverse Voltage (VRRM): 1000V
• Package: DO-15 (Axial Lead, Through Hole)
• Low reverse leakage current for improved energy efficiency
• High surge current capability — handles temporary overloads reliably
• High-temperature soldering supported: 260°C / 10 seconds
• Operating Temperature Range: –50°C to +150°C
• RoHS compliant — Lead-free, environment-safe construction
• Flame-retardant epoxy molding compound

Applications:

• AC to DC power supply rectification
• Inverters and UPS systems
• Battery chargers
• RO water purifiers and DTH set-top box power boards
• Freewheeling diode in motor control circuits
• Voltage converters and regulators
• General-purpose circuit protection

Why Choose LRM 5399?

With 1000V blocking capability, the LRM 5399 outperforms standard diodes like the 1N4007 in high-voltage applications. Its low forward voltage drop and high surge tolerance make it a top pick for engineers, students, and electronics repair professionals across India.
