1. Reverse Leakage Current (Ir @ Vr): The SSA23L specifies 200µA @ 30V, while the B230A is rated at 500µA @ 30V. The B230A exhibits 150% higher leakage current, which can lead to increased static power dissipation and potential thermal buildup, especially under high-temperature operation or near rated voltage. This may affect system efficiency and high-temperature reliability. 2. Forward Voltage Drop (Vf @ If): The SSA23L measures 490mV, compared to 500mV for the B230A. The B230A shows slightly higher conduction loss (approximately 2%), which may generate marginally more heat in high-current or continuous conduction applications, though the impact is generally negligible for most designs. 3. Junction Capacitance (Cj): Data is not provided for the SSA23L, while the B230A specifies 200pF @ 4V, 1MHz. In high-speed switching circuits (e.g., high-frequency rectification, signal clamping), capacitance directly affects switching speed and noise. If the original design relies on the low capacitance characteristics of the SSA23L, substitution may introduce signal integrity issues.
