Equivalent & Substitute Parts for P4SMA6.8CA-M3/61

Part Overview

The P4SMA6.8CA-M3/61 from Vishay General Semiconductor - Diodes Division is a bidirectional transient voltage suppressor (TVS) diode designed for general-purpose circuit protection. This device clamps transient voltages to a safe level, safeguarding sensitive electronic components. Rated for a 5.8V reverse standoff voltage, a 10.5V maximum clamping voltage at 38.1A peak pulse current, and 400W peak pulse power, it is housed in a surface mount DO-214AC (SMA) package. The part is ROHS3 compliant, supports -65°C to 150°C operating temperature, and is currently active. The need for alternative models arises due to supply chain optimization, multiple sourcing, or inventory requirements.
