The 1N4730A is a 3.9V Zener Diode from On Semiconductor, part of the 1N4728A-1N4758A series. It is designed for voltage regulation and clamping applications requiring a precise 3.9V reference.
Key electrical specifications include a nominal zener voltage of 3.9V with a tolerance of ±5%, a test current of 64 mA, and a maximum zener impedance of 9 Ω at the test current. The device can dissipate up to 1W of power at lead temperatures up to 50°C, with a derating factor of 6.67 mW/°C above that. The maximum leakage current is 50 µA at a reverse voltage of 1V.
The diode is packaged in a DO-41 (DO-204AL) glass axial lead case, suitable for through-hole mounting. It has an operating temperature range of -65°C to +200°C.
The nominal zener voltage is 3.9 V.
The power dissipation is 1 W at lead temperatures up to 50°C, derated above 50°C at 6.67 mW/°C.
The device is available in a DO-41 (DO-204AL) axial lead through-hole glass package.
The maximum zener impedance (Zzt) is 9 Ω at a test current of 64 mA.
The maximum leakage current is 50 µA at a reverse voltage of 1 V.
