1N4751A-TR Description

Short technical summary and product information.

The 1N4751A-TR is a silicon planar power Zener diode from Vishay, designed for voltage stabilization and clipping circuits requiring high power rating. It features a nominal Zener voltage of 30V with ±5% tolerance and a power dissipation of 1.3W (valid when leads at 4mm from case are at ambient temperature, tp=10ms). Key electrical characteristics include a maximum impedance of 40Ω, forward voltage of 1.2V at 200mA, and reverse leakage current of 5µA at 22.8V. The device operates with a junction temperature up to 175°C and can be stored from -65°C to +175°C.

 

The diode is housed in a DO-204AL (DO-41) axial leaded package, suitable for through-hole mounting. It has a thermal resistance junction-to-ambient of 110 K/W. The component is rated MSL level 1 (unlimited) and is offered in tape and reel packaging with 5000 units per reel. RoHS3 compliance is indicated but unverified.
