S1B Description

Short technical summary and product information.

The Vishay Dale S1B is a single rectifier diode in a low-profile SMA (DO-214AC) package, ideal for automated placement. It features a glass-passivated pellet chip junction, providing a low forward voltage drop and low leakage current.

Key electrical characteristics include an average forward current of 1.0 A and a maximum recurrent peak reverse voltage (VRRM) available in several ratings, including 50V, 100V, 200V, 400V, 600V, 800V, and 1000V. The S1B variant specifically offers up to 100V.

This rectifier is designed for use in general-purpose rectification within power supplies, inverters, converters, and as freewheeling diodes. Its high forward surge capability and operating temperature range of -55 °C to +175 °C make it suitable for consumer, automotive, and telecommunication applications. The molding compound meets UL 94 V-0 flammability rating, and the terminals are matte tin plated for solderability.
