Microchip Technology 1N4551A is a Zener diode designed for voltage regulation applications. This component features a nominal Zener voltage of 4.7 V with a ±10% tolerance. It is capable of dissipating a maximum power of 50 W, making it suitable for high-power regulation tasks. The diode exhibits a low impedance of 0.12 Ohms (Max) at its test current. It is housed in a DO-5 (DO-203AB) stud mount package, facilitating efficient thermal management and robust mounting. The operating temperature range is from -65°C to 175°C. Applications for this device include power supplies, voltage clamping, and surge protection in industrial and automotive systems. Forward voltage is rated at a maximum of 1.5 V at 10 A, with a reverse leakage of 100 µA at 1 V.
