1N4728A Description

Short technical summary and product information.

The Vishay Dale 1N4728A is a silicon planar power Zener diode suitable for applications requiring voltage stabilization and clipping. It operates with a nominal Zener voltage range of 3.3V to 75V, with the 1N4728A specifically rated at 3.3V.

 

This diode offers a power dissipation capacity of up to 1.3W and features a standard voltage tolerance of ±5%. It is housed in a DO-41 (DO-204AL) axial package, designed for through-hole mounting. The junction temperature can reach up to 175°C, with a storage temperature range of -65°C to +175°C.

 

Key electrical characteristics include a maximum forward voltage of 1.2V at 200mA and a typical reverse leakage current of 100μA at 1V. The diode is rated for a test current up to 76mA. The DO-41 package has a weight of approximately 310 mg and is molded with UL 94 V-0 rated compound. It is supplied in bulk packaging with a standard package quantity of 5000 units per reel.
