JAN1N4946

Product Overview

Category

The JAN1N4946 belongs to the category of semiconductor diodes.

Use

It is commonly used in electronic circuits for rectification and voltage regulation.

Characteristics

  • Forward voltage drop: 1V
  • Maximum reverse voltage: 100V
  • Maximum forward current: 1A
  • Fast switching speed

Package

The JAN1N4946 is typically available in a DO-41 package.

Essence

This diode is essential for converting alternating current (AC) to direct current (DC) and for protecting circuits from reverse voltage.

Packaging/Quantity

It is usually packaged in reels or tubes, with quantities varying based on manufacturer specifications.

Specifications

  • Forward Voltage Drop: 1V
  • Reverse Voltage: 100V
  • Forward Current: 1A
  • Reverse Recovery Time: <4ns
  • Operating Temperature Range: -65°C to 175°C

Detailed Pin Configuration

The JAN1N4946 has two pins, an anode, and a cathode. The anode is connected to the positive terminal of the circuit, while the cathode is connected to the negative terminal.

Functional Features

  • Rectification: Converts AC to DC by allowing current flow in only one direction.
  • Voltage Regulation: Maintains a relatively constant output voltage.

Advantages

  • Fast switching speed
  • Low forward voltage drop
  • High reverse voltage capability

Disadvantages

  • Limited maximum forward current compared to some other diode models
  • Sensitive to temperature variations

Working Principles

The JAN1N4946 operates based on the principle of creating a depletion region within the diode when reverse-biased, preventing current flow. When forward-biased, it allows current to pass through with minimal resistance.

Detailed Application Field Plans
