1. Introduction

The SS26 is a 2A 60V Schottky barrier rectifier diode in the standard SMA (DO-214AC) surface-mount package. It provides low forward voltage drop below 0.7V for high-efficiency rectification in DC/DC converters and polarity protection circuits. Its fast switching characteristic makes it ideal for applications above 20 kHz where switching losses matter.

The SS26 is an industry-standard Schottky part number compatible across all major manufacturers including Vishay, ON Semiconductor, Diodes Incorporated, STMicroelectronics, Taiwan Semiconductor, MCC, and Good-Ark. YINT Electronics manufactures this model as a fully compatible drop-in replacement with identical SMA package dimensions and improved electrical margins. The device handles 50A surge current for startup and fault conditions.

Engineers looking for an SS26 replacement or SS26 alternative can specify the YINT SS26 as a direct equivalent. It offers low forward voltage for high efficiency and tight reverse leakage control for reliable performance across temperature. YINT's manufacturing includes 100% electrical testing on every device, giving designers full confidence in their power supply and protection circuits.

2. Product Overview

The SS series is one of the most popular Schottky diode families used in low-voltage power electronics. It covers forward current ratings from 1A to 5A with reverse voltages from 20V to 100V in the compact SMA footprint. Each part delivers the low VF and fast switching needed for efficient DC/DC conversion, reverse polarity protection, and freewheeling applications.

The SS26 is a 2A 60V variant suitable for 12V, 24V, and 48V DC systems. Its low forward voltage of 0.7V maximum reduces power dissipation and improves efficiency in output rectification stages. The 50A surge current rating provides margin for startup, capacitive loads, and short-duration fault conditions without device failure.

YINT produces the full SS series from SS12 through SS56 in SMA package. This complete coverage lets customers source all SMA Schottky needs from one manufacturing partner, simplifying supply chain management and reducing qualification costs. The SS26 uses advanced Schottky barrier technology with optimized metal-silicon junction for consistent 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.
