Additional Details:

The HFA04SD60SPBF is typically available in a TO-252 (D-PAK) package. Key specifications include a repetitive peak reverse voltage (VRRM) of 600V, a forward current (IF) of 4A, and a reverse recovery time (trr) of approximately 28 ns. The forward voltage (VF) is typically around 1.6V at 4A. It is designed to operate within a temperature range of -65°C to +175°C. The hyperfast recovery characteristics make it ideal for high-frequency applications where switching losses must be minimized. Proper heat sinking is recommended to maintain optimal performance and ensure long-term reliability. Its soft recovery characteristics are particularly beneficial in applications sensitive to EMI noise, such as motor drives and power supplies.
