The 1N4742A-TR is a 12V Zener diode from Vishay Semiconductors, part of the 1N4728A to 1N4761A series. It offers a nominal Zener voltage of 12V with a tolerance of ±5%, making it suitable for voltage regulation and clipping applications. The diode can dissipate up to 1.3W of power (with leads at 4mm from case at ambient temperature) and has a maximum forward voltage of 1.2V at 200mA. It features a maximum Zener impedance of 9Ω at 1kHz and a reverse leakage current of 5µA at 9.1V. The device is designed for through-hole mounting in a DO-204AL (DO-41) axial lead package. It is rated for operation up to a junction temperature of 175°C. Typical applications include voltage stabilization in power supplies and general purpose voltage reference circuits. The part is RoHS3 compliant and has an MSL of 1 (unlimited).
