1 Amp Rectifier Diodes (50-Pack) | General Purpose 1N400x Series

This bulk 50-pack of 1 Amp rectifier diodes is an essential component for a wide range of basic electronic circuits, particularly in automotive, alarm, and DIY projects. Commonly used for blocking reverse current flow, these reliable diodes are perfect for creating simple one-way electrical valves to protect components, isolate circuits, or convert AC to DC in low-power applications.

Key Features & Specifications:

• Current Rating: 1 Amp (1000mA) Maximum Average Forward Current

• Peak Repetitive Reverse Voltage: Varies by specific model (typically 50V to 1000V for the 1N4001-1N4007 series). Please verify exact voltage rating.

• Type: General Purpose Silicon Rectifier Diode

• Polarity: Anode and Cathode (marked with a stripe on the cathode end).

• Pack Quantity: 50 Pieces

Primary Applications & Benefits:

• Alarm & Automotive Installations: Used to prevent backfeed in wiring systems, such as isolating turn signal circuits to prevent hyper-flashing when adding LED bulbs, or in relay coils to suppress voltage spikes.

• Indicator Flashers: A key component in building simple electronic flasher circuits for LEDs or lamps.

• Polarity Protection: Safeguards sensitive circuits from damage if the power supply is connected backwards.

• Basic Rectification: Converts AC to pulsed DC in low-current power supplies, battery chargers, or hobbyist projects.

• Flyback Diode / Snubber: Used across relay coils or solenoids to clamp the inductive voltage spike when de-energized, protecting switching transistors or ICs.

How It Works:
A diode allows current to flow freely in one direction (from anode to cathode) while blocking it in the reverse direction. The cathode end is marked with a painted band or stripe.

Common Use Cases:

• LED Turn Signal Resistor Alternative: Wired in series to create a voltage drop and prevent hyper-flash without the heat of a load resistor.

• Relay Coil Protection: Placed in parallel (reverse-biased) across a relay coil to absorb the back-EMF spike.

• Circuit Isolation: Preventing one circuit from feeding back into another when multiple power sources or grounds are involved.

Package Includes: 50 x 1 Amp General Purpose Rectifier Diodes.
