• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 490 mV @ 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 160 µA @ 20 V
• Capacitance @ Vr, F: 46 pF @ 10V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: PowerDI™ 323
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C ~ 125°C

Technology:

• Schottky diode classification

Parts meeting all these criteria are electrically and mechanically interchangeable with the PD3S220L-7-2477.

Parameter Comparison

Engineering Selection Recommendations

The PD3S220L-7 is the direct substitute for the obsolete PD3S220L-7-2477. Both parts are manufactured by Diodes Incorporated and share identical electrical and mechanical specifications. The primary distinction is product status: PD3S220L-7-2477 is Obsolete, while PD3S220L-7 is Active and in full production.

Both parts carry ROHS3 Compliant and REACH Unaffected certifications, ensuring regulatory compliance for new designs and production. The PD3S220L-7 is available in Tape & Reel (TR) packaging with Moisture Sensitivity Level (MSL) 1 (Unlimited), providing superior handling and storage characteristics compared to the obsolete variant.

For all new designs and component procurement, the PD3S220L-7 is the appropriate selection. Existing designs using PD3S220L-7-2477 can transition to PD3S220L-7 without circuit modification or re-qualification, as all functional and mechanical parameters are identical.
