1SMB15AT3 Description

Short technical summary and product information.

The 1SMB15AT3 is a 600W peak power unidirectional transient voltage suppressor diode from ON Semiconductor, part of the 1SMB5.0AT3 series. It is designed to protect voltage-sensitive components from high voltage, high energy transients. Key electrical characteristics include a working peak reverse voltage of 15V, a maximum clamping voltage of 24.4V, and a zener breakdown voltage range of 6.7V to 199V for the series. The device features a fast response time of typically 1.0 ns, low reverse leakage current of 5.0 µA maximum above 10V, and an ESD rating of Class 3 (>16 kV) per the Human Body Model. It also meets UL 497B for isolated loop circuit protection.

 

The 1SMB15AT3 is housed in a surface mount SMB (DO-214AA) package with modified L-bend leads for improved solder joint contact area. It supports an operating and storage temperature range of -65°C to +150°C and a maximum soldering temperature of 260°C for 10 seconds. The device is supplied in tape and reel packaging with a standard quantity of 2500 units. Pb-free packages are available as indicated in the datasheet.

 

Typical applications include communication systems, automotive electronics, numerical controls, process controls, medical equipment, business machines, and power supplies. The device's high surge capability and low zener impedance make it suitable for a wide range of industrial and consumer applications requiring transient protection.
