The 5.6 V nominal breakdown voltage with ±10% tolerance makes it a straightforward choice for low-voltage rail clamping, shunt regulation, or as a reference in a bias network — the 5 Ohm maximum Zener impedance (Zzt) keeps the voltage shift under a few hundred millivolts across the rated current range. ## Temperature range and thermal budget The 1 W power limit in the DO-41 body means the junction-to-ambient thermal path relies on the lead length and board copper — derate above 25°C ambient per the standard Zener derating curve. The 1.2 V forward drop at 200 mA (If) is typical for the silicon die; reverse leakage is 10 µA max at 2 V reverse bias, confirming the breakdown knee is sharp enough for most regulator circuits. ## Active lifecycle and reel format The TR suffix indicates Tape & Reel packaging, which feeds automated pick-and-place for through-hole insertion (the reel holds the axial leads taped per EIA-296). Sourced to order against BOM quantities; availability and current pricing confirmed at RFQ.","metaTitle":"1N4734E3/TR13 Zener Diode, 5.6 V, 1 W, DO-41, Microchip","metaDescription":"Microchip 1N4734E3/TR13 Zener diode, 5.6 V nominal, 1 W, ±10% tolerance, DO-204AL (DO-41) axial package.
