onsemi 1N4743ATR is a high-quality Zener diode designed for electronic and electrical circuits requiring voltage regulation and stabilization. This single element general purpose diode has a nominal zener voltage of 13 V and a maximum power dissipation rating of 1 watt. Housed in a DO-41 package, it features a through-hole mounting style with 2 pins, allowing for easy and reliable circuit board installation.
The device operates effectively across a wide temperature range from -65°C to 200°C, making it suitable for industrial, commercial, and laboratory applications. Its maximum zener impedance of 10 ohms and a tight voltage tolerance of ±5% ensure stable performance in precision circuits. The maximum reverse leakage current of 5 microamps further reduces inefficiencies in circuit operation.
The compact physical dimensions of 5.2mm length and 2.72mm height enable application in space-constrained environments. These technical attributes allow the diode to be widely used in power supplies, voltage reference sources, and protective circuits against voltage surges in manufacturing and electronic assembly industries.
The diode has a through-hole mount type with 2 pins for secure installation. It supports a maximum power dissipation of 1 watt with a test current of 19 mA. The zener voltage tolerance is ±5% enabling precise voltage regulation.
The temperature operating range is from -65°C to 200°C for reliable performance in harsh conditions. Maximum zener impedance is 10 ohms to control voltage fluctuations effectively. The device exhibits a maximum reverse leakage current of 5 microamps reducing unwanted current flow.
Compact DO-41 package dimensioned 5.2mm length x 2.72mm height ensures fitting in limited space. Suited for industrial, laboratory, and manufacturing electronics requiring voltage stabilization.
