The ±2% tolerance on the nominal voltage means it holds the regulation band tighter than the standard 5% Zener — useful if you are building a reference or a fixed shunt regulator where the output voltage tolerance matters more than the absolute value. A 5.6 V Zener at 1 W can sink about 178 mA continuous before hitting the dissipation limit at 25 °C ambient — derate for elevated temperature. The low 5-Ohm Zzt impedance (max) keeps the voltage stable under varying current, which helps in clamp circuits or as a low-cost voltage reference. ## Temperature range and package reality This Zener works in engine-bay electronics, downhole tools, or sealed outdoor modules where the ambient hits extremes. The DO-41 axial body is through-hole; it hand-solders easily and tolerates rework well, but for automated assembly the Tape & Reel packaging (TR suffix) feeds pick-and-place if you use a carrier tape adapter. Reverse leakage is specified at 10 µA max at 2 V reverse — low enough that it won't drain a battery-powered circuit in standby. Forward voltage drop is 1.2 V max at 200 mA, typical for a 1 W Zener. ## Active production — no LTB clock ticking Microchip lists the 1N4734CE3/TR13 as Active. No end-of-life notice, no last-time-buy window. This part can be designed into new builds without worrying about a sunset date.","metaTitle":"1N4734CE3/TR13 Microchip Zener 5.6V 1W ±2% DO-41","metaDescription":"Microchip 1N4734CE3/TR13 Zener diode, 5.6 V nominal, 1 W, ±2% tolerance, DO-41 axial.
