1N4743A-T Description

Short technical summary and product information.

The 1N4743A-T is a 13V Zener diode from Diodes Incorporated, designed for 1W power dissipation. It features a nominal Zener voltage of 13V with ±5% tolerance and a test current of 19mA. The diode offers a maximum Zener impedance of 10Ω at IZT and 700Ω at IZK. Reverse leakage current is 5µA at 9.9V. The forward voltage is 1.2V at 200mA. This device is housed in a DO-41 (DO-204AL) glass package with axial leads for through-hole mounting. It is RoHS compliant with lead-free terminal finish (Sn96.5Ag3.5). The operating temperature range is -65°C to 175°C. Thermal resistance is 175°C/W. The diode is not recommended for new designs; the DFLZxx series is suggested as replacement.
