Additional Details:

The SMF48A-M-08 features a standoff voltage (Vrwm) of 48V and a peak pulse power dissipation of 200W. It operates over a temperature range of -65°C to +150°C. The device meets MSL Level 1 per J-STD-020, indicating that it is not moisture sensitive. The ‘-M’ in the part number often indicates a specific manufacturing or testing process. The '08' might be related to tape and reel packaging. The unidirectional configuration of the SMF48A-M-08 ensures that it conducts only when the voltage exceeds the breakdown voltage in one direction, providing targeted protection against positive voltage transients. Vishay is a reputable manufacturer known for its high-quality semiconductor devices, making the SMF48A-M-08 a reliable choice for circuit protection applications.
