1N5373BRLG Description

Short technical summary and product information.

The 1N5373BRLG is a 5W Zener voltage regulator diode from On Semiconductor (onsemi), part of the 1N53 series. It provides a nominal Zener voltage of 68V with ±5% tolerance in a through-hole axial lead package.

 

Key electrical characteristics include a Zener impedance of 44Ω, reverse leakage current of 500nA at 51.7V, and forward voltage of 1.2V at 1A. The diode is rated for 5W power dissipation with derating above 25°C at 40mW/°C. It offers an ESD rating of Class 3 (>16kV) per Human Body Model and a surge rating of 180W for 8.3ms.

 

The device is housed in a T-18, axial lead case and supports operating and storage temperatures from -65°C to 200°C. The junction-to-lead thermal resistance is 25°C/W. The Pb-free version (G suffix) is available, packaged in tape and reel with 4000 pieces per reel.
