1. Introduction

The UF4007 is a 1A 1000V ultra fast recovery rectifier diode in the DO-41 through-hole package. It switches in 75ns and handles high-frequency rectification in switching power supplies, flyback converters, and freewheeling circuits.

The UF4007 is a JEDEC-registered industry standard part cross-compatible with ON Semiconductor, Vishay, Diodes Incorporated, STMicroelectronics, MCC, and Good-Ark. YINT Electronics manufactures the UF4007 as a fully compatible drop-in replacement in the DO-41 package. Its 75ns recovery time reduces switching losses in circuits running above 20 kHz.

Engineers looking for a UF4007 replacement or UF4007 alternative can specify the YINT UF4007 as a direct equivalent. It delivers the same 1000V reverse voltage, 1A forward current, and 75ns reverse recovery time with tight parameter control.

2. Product Overview

The UF400x series covers reverse voltages from 50V (UF4001) to 1000V (UF4007) in the DO-41 through-hole package. Each device delivers 1A continuous forward current with 30A surge capability and sub-100ns recovery for high-frequency operation.

The UF4007 is the highest-voltage variant rated for 1000V reverse blocking with 75ns maximum reverse recovery time. It replaces slower 1N4007 standard rectifiers in switching power supplies and improves efficiency by reducing power loss during reverse recovery. The 1.7V forward drop at 1A and 30A surge rating provide reliable operation under startup and transient conditions.

YINT produces the full UF400x series and complementary fast recovery families. This enables customers to source all rectifier needs from one manufacturing partner with consistent quality and supply.

10. FAQ

Q1: Is YINT UF4007 a direct replacement for ON Semi / Vishay UF4007?
A: Yes. The YINT UF4007 has identical electrical specs and DO-41 package dimensions. It is a drop-in replacement for UF4007 from all major manufacturers.

Q2: What is the difference between UF4007 and 1N4007?
A: The UF4007 has 75ns reverse recovery time, while the 1N4007 has 2µs standard recovery. Use UF4007 for circuits switching above 20 kHz.

Q3: What is the maximum forward voltage?
A: 1.7V at 1A forward current at 25°C. Typical values are 1.2-1.4V under normal operating conditions.

Q4: Can UF4007 be used in 220V AC rectifier circuits?
A: Yes. The 1000V rating provides adequate margin for 220VAC mains rectification in half-wave and full-wave bridge configurations.

Q5: What is the surge current capability?
A: 30A peak for one half-cycle at 60 Hz (8.3ms). This handles startup inrush and fault transients.

Q6: What package is UF4007 available in?
A: DO-41 (DO-204AL) through-hole. For surface mount, consider US1M (SMA) or RS1M (SMA) equivalents.
