1N4734A-TAP Description

Short technical summary and product information.

The 1N4734A-TAP is a silicon planar power Zener diode from Vishay designed for voltage stabilization and clipping circuits. It provides a nominal Zener voltage of 5.6V with a tolerance of ±5% and a maximum power dissipation of 1.3W. The device features a low Zener impedance of 5Ω at the test current of 45mA and offers a forward voltage drop of 1.2V at 200mA forward current.

 

This through-hole component is housed in the industry-standard DO-204AL (DO-41) package with axial leads, making it suitable for manual and automated insertion. It can operate at a junction temperature up to 175°C and has a storage temperature range from -65°C to +175°C. The thermal resistance from junction to ambient is 110K/W.

 

The part is available in ammopack tape packaging (TAP suffix) with a standard quantity of 5000 units per reel. It is intended for use in stabilizing and clipping circuits where a high power rating is required.
