• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): 30 mA
• Voltage - Forward (Vf) (Max) @ If: 370 mV @ 1 mA
• Current - Reverse Leakage @ Vr: 1 µA @ 10 V
• Operating Temperature - Junction (Max): 125°C
• Mounting Type: Surface Mount
• Package / Case: SOT-523
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

The CDBH3-00340-HF is the direct equivalent substitute for the obsolete CDBH3-00340-G. Both components are manufactured by Comchip Technology and share identical electrical and mechanical specifications across all critical parameters.
