1. Introduction

The ES1C is a 1A 150V ultra fast recovery rectifier diode in the standard SMA (DO-214AC) surface-mount package. It features a maximum reverse recovery time of 35ns for low switching losses in high-frequency power supplies. Its fast switching characteristic makes it ideal for continuous conduction mode and critical conduction mode flyback converters.

The ES1C is an industry-standard fast recovery part number compatible across all major manufacturers including Vishay, ON Semiconductor, Diodes Incorporated, STMicroelectronics, MCC, Good-Ark, and Taiwan Semiconductor. YINT Electronics manufactures this model as a fully compatible drop-in replacement with identical SMA package dimensions and matched recovery time. The device handles 30A surge current for startup and transient conditions.

Engineers looking for an ES1C replacement or ES1C alternative can specify the YINT ES1C as a direct equivalent. It offers 35ns fast recovery for low switching loss above 20 kHz and low forward voltage drop for standard efficiency operation. YINT's manufacturing includes 100% electrical testing on every device, giving designers full confidence in their high-frequency power supply designs.

2. Product Overview

The ES1 series is one of the most widely used fast recovery diode families in switching power supplies. It covers forward current ratings from 1A with reverse voltages from 50V to 600V in the compact SMA footprint. Each part delivers the fast trr needed for efficient high-frequency rectification in flyback, forward, and resonant converter topologies.

The ES1C is a 1A 150V variant suitable for 12V to 100V DC output stages. Its maximum 35ns recovery time minimizes turn-off losses in converters switching above 20 kHz. The 30A surge current rating provides margin for startup, capacitive loads, and short-duration fault conditions without device failure. The 0.95V maximum forward voltage is typical for fast recovery type diodes at rated current.

YINT produces the full ES1 series from ES1A through ES1J in SMA package. This complete voltage coverage lets customers source all SMA fast recovery diode needs from one manufacturing partner, simplifying supply chain management and reducing qualification costs. The ES1C uses advanced epitaxial silicon technology with optimized lifetime control for consistent trr, VF, and IR performance across every production lot. YINT's 19+ years of experience in semiconductor manufacturing means every device benefits from mature, proven production processes that deliver reliable long-term performance.
