Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S2KDF-13 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
• Current - Reverse Leakage @ Vr: 5 µA @ 800 V
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Capacitance @ Vr, F: 8 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: 2-SMD, Flat Lead
• Mounting Type: Surface Mount
• Supplier Device Package: D-Flat

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The S2KDFQ-13 meets all electrical, mechanical, and compliance requirements and is therefore a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the S2KDF-13 and S2KDFQ-13 are Active product status components manufactured by Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is based on application requirements:

S2KDF-13 is suitable for general-purpose applications requiring standard rectifier performance with RoHS3 compliance and unlimited moisture sensitivity rating.

S2KDFQ-13 is suitable for automotive and high-reliability applications, as it carries AEC-Q101 qualification in addition to all standard compliance certifications. The AEC-Q101 qualification indicates enhanced reliability testing and qualification for automotive-grade applications.

Both parts are ROHS3 compliant, REACH unaffected, and maintain identical electrical performance across the specified operating temperature range of -55°C to 150°C junction temperature.
