1N5344BG Description

Short technical summary and product information.

The 1N5344BG is a 5-watt Zener voltage regulator diode from On Semiconductor, part of the 1N53 series. It features a nominal Zener voltage of 8.2V with a tolerance of ±5%. The device is designed for through-hole mounting in a T-18 axial lead package, with a cathode indicated by a polarity band.

 

Key electrical characteristics include a forward voltage of 1.2V at 1A, reverse leakage current of 10µA at 6.2V, and a Zener impedance of 1.5Ω. The diode can dissipate up to 5W at a lead temperature of 25°C (derated at 40mW/°C above 25°C) and has a junction-to-lead thermal resistance of 25°C/W. It operates over a temperature range of -65°C to 200°C.

 

The device offers an ESD rating of Class 3 (>16 kV) per the Human Body Model and a surge rating of 180W at 8.3ms. The maximum lead temperature for soldering is 260°C for 10 seconds. The 1N5344BG is suitable for voltage regulation, overvoltage protection, and other general-purpose Zener applications.
