onsemi Small Signal Schottky Diode 100 V 200 mA Surface Mount SOD-523 1SS400T1G

onsemi 1SS400T1G Small Signal Schottky Diode is a surface mount device designed for high-speed switching and rectification applications. Rated for a peak reverse repetitive voltage (Vrrm) of 100 V and maximum continuous forward current of 200 mA, this diode offers robust performance in compact form factor.

Encapsulated in an SOD-523 package, it measures 1.3 mm in length, 0.9 mm in width, and 0.7 mm in height, making it ideal for dense PCB assemblies where board space is limited. The diode configuration is single, with two pins for electrical connection, optimized for efficient small signal switching.

This diode features a low maximum forward voltage (Vf) of 1.2 V to minimize conduction losses and a very fast peak reverse recovery time (trr) of 4 ns, suitable for applications requiring quick switching transitions such as power management and signal rectification in telecommunications, consumer electronics, and automotive electronics.

The device supports a wide operating temperature range from -55°C up to 150°C, ensuring reliability in extreme thermal conditions. Additionally, the diode conforms to AEC-Q101 automotive standards, underscoring its suitability for automotive and industrial environments requiring stringent quality and durability.

Applications include general-purpose rectification, DC/DC converters, clamping and protection circuits, and ultra-fast switching circuits in industrial, automotive, and consumer electronic devices.

Maximum continuous forward current of 200 mA ensures reliable operation under moderate load. Peak reverse repetitive voltage rating of 100 V provides good voltage blocking capability. Low forward voltage of 1.2 V minimizes power loss in switching applications.

Small signal diode configuration suitable for high-speed switching tasks. Compact package size of 1.3mm length, 0.9mm width, and 0.7mm height for space-constrained PCB layouts. Automotive grade AEC-Q101 qualification guarantees high quality and reliability.

Operating temperature range from -55°C to 150°C supports harsh environments. Fast peak reverse recovery time of 4 ns enhances switching efficiency. Peak non-repetitive forward surge current of 500 mA allows tolerance for transient current spikes.
