1. Introduction

The 1N4006 is a 1A 800V standard recovery rectifier diode in the DO-41 through-hole package. It converts AC to DC in power supplies and general-purpose rectification circuits where 800V reverse blocking is required. The device has a forward voltage of 1.1V max and a peak surge current rating of 30A.

The 1N4006 is a JEDEC-registered industry standard part used across all major diode manufacturers including ON Semiconductor, Vishay, Diodes Incorporated, STMicroelectronics, MCC, and Good-Ark. YINT Electronics manufactures the 1N4006 as a fully compatible drop-in replacement in the DO-41 package. The device handles medium-voltage rectification in industrial and consumer equipment.

Engineers looking for a 1N4006 replacement or 1N4006 alternative can specify the YINT 1N4006 as a direct equivalent. It offers the same 800V reverse voltage rating and 30A surge capability with reliable parameter control. YINT uses automated assembly and 100% electrical testing on every device for consistent performance.

2. Product Overview

The 1N400x series is the most widely used standard rectifier diode family in electronics. It covers reverse voltages from 50V (1N4001) to 1000V (1N4007) in the DO-41 through-hole package. The 1N4006 at 800V fills the gap between 600V (1N4005) and 1000V (1N4007) for applications with intermediate voltage requirements.

The 1N4006 handles full-wave and half-wave rectification in power supplies, chargers, and ballasts with 800V peak input. The 1.1V forward drop and 30A surge rating provide reliable operation under startup and fault conditions. It is also a common choice for freewheeling and snubber circuits in higher-voltage switching converters.

YINT produces the full 1N400x series from 1N4001 through 1N4007, offering complete voltage coverage in the standard DO-41 package. YINT's 19+ years of semiconductor manufacturing experience means every device benefits from mature production processes and proven long-term reliability.
