Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 240 V
• Current - Average Rectified (Io) (per Diode): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 240 V
• Operating Temperature - Junction: -65°C ~ 150°C

Mechanical Parameters:

• Diode Configuration: 1 Pair Series Connection
• Mounting Type: Surface Mount
• Package / Case: SOT-563, SOT-666
• Technology: Standard

Compliance Parameters:

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

Substitute parts must match all parameters listed above without deviation. Parts meeting these criteria are electrically and mechanically interchangeable within the specified operating conditions.
