Product Parameters
Operating Voltage Range: 60V: DC 3.5-60V / 90V: DC 4-90V
Operating Current: 20A (For over 15A, please enhance heat dissipation)
Static Operating Current: 300uA
On-Circuit Resistance: 60V: 4.6mΩ / 90V: 3.6mΩ
On-Circuit Voltage Drop: Actual operating current * on-circuit resistance, e.g., at 10A, voltage drop = 10 * 0.0036 = 0.046V
Power Loss During Conduction: Squared actual operating current * on-circuit resistance, e.g., at 10A, power consumption = 10 * 10 * 0.0046 = 0.36W
Turn-On Frequency: Within 150Hz
Input Reverse Connection Protection: Yes, reverse connection will not burn out
Operating Temperature: -40~+125°C
Precautions
1. The negative terminal of the main current loop does not need to pass through the module, but the negative terminal on the module must be connected (a thin wire can be used).
2. Can only be used with DC power, operating frequency not exceeding 150Hz, and cannot be used for AC rectification.
3. Beware of surge voltage damage to the chip. For higher operating voltages or inductive loads, add TVS diodes and electrolytic capacitors at the input and output to absorb surge voltage.
4. Due to the large operating current and significant heat generation, enhanced heat dissipation is required (larger heatsink or air cooling).
5. Multiple diodes can be connected in parallel to increase current or increase the number of channels.
6. When using main/secondary batteries in parallel, if the main battery does not have an ideal diode, ensure the secondary battery voltage does not exceed the main battery voltage. If both main and secondary batteries have ideal diodes connected, there is no voltage difference requirement when connected in parallel.
7. Do not use the diode and resistance settings of a multimeter to measure the internal resistance of an ideal diode. This is an incorrect measurement method. The internal resistance can be calculated from the voltage drop across the ideal diode and the current flowing through it. For example: If the current is currently 10A, the voltage drop is 0.015V, and the internal resistance is 0.015V/10A = 0.0015 ohms, the effect of the line voltage drop needs to be considered.
