Visão Geral

Description

The UF4007 is a standard recovery rectifier diode designed for high-efficiency switching applications. Key features:
- Fast recovery time (~75 ns), reducing switching losses.
- High current capability (1A average forward current).
- Peak repetitive reverse voltage of 1000V, suitable for high-voltage circuits.
- Low forward voltage drop (~1.7V at 1A), improving efficiency.
Commonly used in:
- Power supplies (SMPS, inverters).
- Freewheeling/clamping circuits.
- General-purpose rectification.
Packaged in a DO-41 form factor, it’s robust and widely available. Its performance makes it a cost-effective alternative to slower rectifiers like the 1N4007 in high-frequency applications.

Equivalent

The UF4007 is a fast recovery diode (1A, 1000V). Equivalent alternatives include:
- 1N4007 (slower, general-purpose)
- 1N4937 (fast recovery, 1A, 600V)
- FR107 (fast recovery, 1A, 1000V)
- HER108 (ultrafast, 1A, 1000V)
- SF18 (fast recovery, 1A, 800V)
For ultrafast performance, consider ES1J (1A, 600V) or UF4004-UF4007 series variants. Verify specs for compatibility.

Features

The UF4007 is a fast recovery rectifier diode with the following key features:
- Type: Ultrafast rectifier diode
- Max Reverse Voltage (VRRM): 1000V
- Average Forward Current (IF(AV)): 1A
- Peak Forward Surge Current (IFSM): 30A (non-repetitive)
- Forward Voltage Drop (VF): ~1.7V at 1A
- Reverse Recovery Time (trr): ≤75ns (ultrafast switching)
- Operating Temperature: -65°C to +175°C
- Package: DO-41 (axial leaded)
Designed for high-efficiency switching applications, it’s commonly used in power supplies, inverters, and freewheeling circuits. Its ultrafast recovery minimizes switching losses.

Pinout

The UF4007 is a fast recovery rectifier diode with 2 pins (anode and cathode).
Key Functions:
- High-speed switching (50 ns recovery time)
- Peak reverse voltage: 1000V
- Average forward current: 1A
- Low forward voltage drop (~1.7V at 1A)
Applications:
- Power supplies
- Freewheeling diodes
- Reverse polarity protection
Pinout:
1. Anode (A) – Positive terminal
2. Cathode (K) – Negative terminal (marked with a stripe)
Compact and efficient for high-voltage, fast-recovery needs.

Application

The UF4007 is a fast recovery diode commonly used in:
1. Power Supplies – Rectification in switch-mode power supplies (SMPS).
2. DC-DC Converters – High-frequency voltage conversion.
3. Freewheeling Diodes – Protecting circuits from back EMF in inductive loads.
4. Reverse Polarity Protection – Safeguarding circuits from incorrect power connections.
5. High-Speed Switching – Applications requiring fast recovery (50ns typical).
Its low forward voltage drop (1V max) and high efficiency make it suitable for high-frequency and energy-sensitive designs.

Package

The UF4007 is a fast recovery rectifier diode available in a DO-41 package. This is a standard axial-leaded package with a cylindrical shape, commonly used for through-hole mounting. The DO-41 package has a typical diameter of 2.7mm and a length of around 5.2mm, making it suitable for general-purpose rectification in power supplies and other electronic circuits.
