The ±10% tolerance on the nominal zener voltage means the actual breakdown sits between 10.8 V and 13.2 V at the test current — a band that covers most 12 V rail-clamping and reference applications without tighter binning. With a maximum impedance of 9 Ohms (Zzt), the diode holds the regulation slope tight enough for a 12 V bus in a linear regulator pre-regulator or a low-power TVS role. The 5 µA reverse leakage at 9.1 V confirms the junction is clean — no early breakdown eating into the standby budget. ## Temperature grade and through-hole mounting The DO-41 axial body solders into a 0.036-inch (0.9 mm) diameter hole on a standard 0.100-inch pitch — no reflow profile needed, just a wave or hand-solder step. Supplied on tape and reel (TR suffix), the parts are sequenced for automated insertion equipment. The reel quantity is set by the manufacturer; confirm the exact count per reel at RFQ time.","metaTitle":"Microchip 1N4742E3/TR13 Zener Diode, 12 V, 1 W, DO-41","metaDescription":"Active Microchip Technology 1N4742E3/TR13 zener diode, 12 V nominal, 1 W, DO-41 axial, ±10% tolerance.
