1. Recovery Speed and Reverse Recovery Time - RL105GP-TP is a standard recovery diode (>500ns), while AG01AWK is a fast recovery diode (trr = 100ns). - AG01AWK is suitable for higher-frequency switching circuits (e.g., switching power supplies, high-frequency rectification), whereas RL105GP-TP is only appropriate for line-frequency or low-frequency rectification. Direct substitution may cause RL105GP-TP to overheat and fail under high-frequency operation. 2. Forward Voltage Drop (Vf) and Rated Current - RL105GP-TP: Vf ≤ 1.1V at 1A; AG01AWK: Vf ≤ 1.8V at 600mA. - AG01AWK exhibits a significantly higher Vf, leading to greater conduction loss and lower efficiency at the same current. Its rated current of 500mA is also lower than the 1A rating of RL105GP-TP, requiring derating and potentially limiting power handling capability. 3. Reverse Leakage Current and Voltage Withstanding Characteristics - RL105GP-TP leakage current is only 5µA @ 600V, while AG01AWK reaches 100µA @ 600V (a 20× difference). - The higher leakage current of AG01AWK may cause additional power dissipation or voltage stability issues in high-impedance or high-temperature circuits, making it unsuitable for high-precision or low-power applications. 4. Structure and Thermal Design - AG01AWK does not provide capacitance parameters and uses a ceramic package (common for high-frequency diodes); RL105GP-TP specifies a capacitance of 15pF @ 4V. - AG01AWK may be optimized for high frequency, but its high Vf and leakage current offset its speed advantage. The capacitance characteristics of RL105GP-TP are more suitable for suppressing low-frequency noise. Recommendation: If substitution is necessary, it should be limited to low-frequency rectification applications with current ≤ 500mA, and thermal rise and efficiency loss must be evaluated. For switching power supplies or high-frequency applications, a fast recovery diode with lower Vf and matching current rating should be selected.
