1N4007 1W Diode

Description

A 1N4007 Diode is one of the most widely used general-purpose silicon rectifier diodes in electronics. It is designed to allow electrical current to flow in only one direction (from anode to cathode) while blocking reverse current, making it a staple for power conversion and circuit protection.

Key Features & Specifications

• Diode Type: Silicon Rectifier Diode (Standard Recovery).

• Maximum Repetitive Peak Reverse Voltage ($V_{RRM}$): $1,000\text{V}$ (the highest reverse voltage it can block safely).

• Average Forward Rectified Current ($I_{F(AV)}$): $1\text{A}$ (maximum continuous forward current).

• Non-Repetitive Peak Surge Current ($I_{FSM}$): Up to $30\text{A}$ (handles short current spikes).

• Package Type: DO-41 (axial lead, through-hole design with a glass-passivated plastic body).

Common Applications

• Rectification: Converting AC (Alternating Current) to DC (Direct Current) in power supply circuits (such as bridge rectifiers).

• Flyback Protection / Freewheeling Diode: Placed in reverse-bias across inductive loads like DC motors, relays, or solenoids to absorb high-voltage back-EMF spikes when the circuit switches off, protecting transistors and microcontrollers (like your STM32 or MOSFET modules).

• Reverse Polarity Protection: Protecting sensitive circuit boards if power supply leads are accidentally swapped.

Price Range & Visual Reference

• Price: Extremely affordable, typically costing between ₹1 to ₹3 per piece, or around ₹20 to ₹40 for a pack of 20.

• Visual Identification / Download Image: Look for a small black cylindrical plastic body with a silver/gray band on one end (indicating the cathode side). You can view and save product photos by searching 1N4007 diode on component storefronts like Robu.in or Quartz Components.
