1N5355B Description

Short technical summary and product information.

The 1N5355B is a 5W Zener voltage regulator diode from On Semiconductor, part of the 1N53 series. It features a nominal Zener voltage of 18V with a tolerance of ±5%. The device is designed for through-hole mounting in a T-18 axial lead package.

 

Key electrical characteristics include a maximum forward voltage of 1.2V at 1A, a maximum reverse leakage current of 500nA at 13.7V, and a maximum Zener impedance of 2.5Ω at the test current. The diode offers an ESD rating of Class 3 (>16 kV) per the Human Body Model and a surge power rating of 180W at 8.3 ms.

 

Thermal specifications include a maximum steady state power dissipation of 5W at 25°C lead temperature (derating 40 mW/°C above 25°C), a junction-to-lead thermal resistance of 25°C/W, and an operating temperature range of -65°C to 200°C. The maximum soldering lead temperature is 260°C for 10 seconds.

 

The device is housed in a void-free, transfer-molded plastic case with corrosion-resistant leads. It is suitable for voltage regulation, overvoltage protection, and general purpose Zener applications.
