Microchip Technology 1N3345RB is a Zener diode featuring a 140V nominal breakdown voltage with a ±5% tolerance. This 50W power-rated component is housed in a DO-5 (DO-203AB) package, designed for chassis or stud mounting. It exhibits a maximum impedance of 60 Ohms at its Zener voltage and a reverse leakage of 10 µA at 114V. The forward voltage drop is a maximum of 1.5V at 10A. Operating across a wide temperature range of -65°C to 175°C, its robust construction and high power dissipation make it suitable for applications in power regulation, voltage clamping, and surge protection within industrial and high-reliability systems.
