Substitute Part Grouping Explanation

Substitution of rectifier diodes is determined by equivalence across electrical ratings and mechanical compatibility. The NHP620LFST1G qualifies for substitution with parts that maintain identical specifications in the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 6 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 6 A
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 500 nA @ 200 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: SOT-1023, 4-LFPAK
• Supplier Device Package: LFPAK4 (5x6)
• Operating Temperature - Junction: -55°C to 175°C
• Mounting Type: Surface Mount

Parts meeting these criteria are electrically and mechanically interchangeable within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the NHP620LFST1G and NRVHP620LFST1G are active production parts from onsemi with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

NHP620LFST1G is the standard general-purpose variant suitable for applications without automotive qualification requirements.
