The 1N749A is a Zener diode from On Semiconductor with a nominal Zener voltage of 4.3V at 20mA test current. It has a ±5% tolerance and a maximum Zener impedance of 22Ω. The diode can handle up to 95mA maximum Zener current and dissipates 500mW at lead temperatures up to 75°C. It is housed in a DO-35 (DO-204AH) glass axial lead package for through-hole mounting. The operating temperature range is -65°C to 200°C. Typical applications include voltage regulation, overvoltage protection, and clamping circuits. The device has a forward voltage of 1.5V at 200mA and a reverse leakage current of 2µA at 1V.
