1N5355BG Description

Short technical summary and product information.

The 1N5355BG is a 5 watt Zener voltage regulator diode from onsemi's 1N53 series. It features a nominal zener voltage of 18V with a tolerance of ±5%. The part is designed for through-hole mounting with axial leads and is housed in a void-free, transfer-molded thermosetting plastic case (Case 017AA).

 

Electrically, the device offers a reverse leakage current of 500 nA at 13.7V, a forward voltage of 1.2V at 1A, and a zener impedance of 2.5Ω. It can handle surge power up to 180W for 8.3 ms and has an ESD rating of Class 3 (>16 kV) per the Human Body Model. The operating junction temperature range is -65°C to 200°C, with a junction-to-lead thermal resistance of 25°C/W.

 

This Zener diode is suitable for voltage regulation, clamping, and protection circuits where 5W of continuous power dissipation is required. The Pb-free (G suffix) version is RoHS3 compliant and REACH unaffected.
