The 1N4733APE3/TR8 is a 5.1 V Zener diode rated for 1 W continuous power dissipation in a DO-204AL (DO-41) axial-lead package. The ±5% tolerance on the nominal voltage means the actual Zener voltage at the test current falls between 4.845 V and 5.355 V — tight enough for most 5 V rail clamping or reference applications, but not a precision voltage reference. The 7 Ohm maximum Zzt impedance at the Zener knee means the voltage shift per mA of current change is small, so the diode holds the rail reasonably flat under varying load. The 10 µA maximum reverse leakage at 1 V reverse bias confirms the diode blocks cleanly below the Zener threshold.

Frequently asked questions
What package does the 1N4733APE3/TR8 come in?
It is supplied in a DO-204AL (DO-41) axial-lead package, on Tape & Reel (TR). The supplier device package is DO-204AL (DO-41).
What is the tolerance on the 1N4733APE3/TR8 Zener voltage?
The tolerance is ±5% on the 5.1 V nominal Zener voltage, so the actual Vz is between 4.845 V and 5.355 V at the test current.
