Each is marked \"Z1318\" with the International Rectifier logo. They come from an original bag with a typed ECG label reading \"ECG-5197A Z-1318 Vol Regl D 22V 10W\". Each has a threaded mounting stud, hex base, and a single solder-lug terminal with a mounting hole. Lug holes are free of solder; no signs of installation. Cases show heavy surface oxidation from long-term storage, as pictured.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003eOriginal International Rectifier manufacture, logo-marked\u003cbr\u003eMarked \"Z1318\" on the case\u003cbr\u003e22 V nominal zener voltage\u003cbr\u003e10 W power dissipation\u003cbr\u003eDO-4 stud package, 10-32 thread\u003cbr\u003eHex base for wrench tightening\u003cbr\u003eSingle solder-lug top terminal\u003cbr\u003eCross-references to ECG5197A \/ NTE5197A\u003cbr\u003e5 pieces\u003cbr\u003e\u003cbr\u003eCompatibility:\u003cbr\u003eReplaces ECG5197A and NTE5197A 22V 10W DO-4 stud zener diodes. NTE lists the NTE5197A at 22 V ±5%, 115 mA test current, 380 mA max DC zener current, with the anode connected to the stud on standard types (the NTE5197AK is the reverse, cathode-to-stud version). Stud polarity of these International Rectifier units has not been tested; confirm with a multimeter's diode-test function before installing.\u003cbr\u003e\u003cbr\u003eQ\u0026amp;A\u003cbr\u003eQ: What is the Z1318?\u003cbr\u003eA: A 22 V, 10 W zener (voltage regulator) diode in a DO-4 stud package, made by International Rectifier. The original ECG label cross-references it to the ECG5197A.\u003cbr\u003eQ: Is the stud the anode or the cathode?\u003cbr\u003eA: On the ECG\/NTE5197A the stud is the anode. These units have not been tested, so confirm with a multimeter's diode-test function before installing.\u003cbr\u003eQ: What thread is the stud?\u003cbr\u003eA: DO-4 packages use a 10-32 thread.\u003cbr\u003eQ: Are mounting nuts or washers included?\u003cbr\u003eA: No. Only the 5 diodes shown are included.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003eItems are new old stock, sold as pictured.
