What Is the CL01-12 High Voltage Diode?
The CL01-12 is a silicon high voltage rectifier diode with a 12kV VRRM rating and 350mA average forward current rating.
Its primary function is to allow current to flow in the forward direction while blocking high reverse voltage. This makes it suitable for converting high-voltage AC into high-voltage DC and for protecting high-voltage rectifier circuits from reverse voltage.
The CL01-12 is designed as a standard-recovery diode, making it more appropriate for conventional high-voltage rectification than applications requiring extremely fast switching.
|
12kV High Voltage Rectification A key specification of the CL01-12 is its 12kV repetitive peak reverse voltage (VRRM). This rating makes the diode suitable for high-voltage rectifier circuits where the reverse voltage across the diode can reach several kilovolts. When selecting a high voltage diode, the VRRM rating should be selected with sufficient margin above the maximum repetitive reverse voltage generated by the actual circuit. For this reason, the CL01-12 can be considered for high-voltage systems requiring a nominal 12kV-class rectifier diode, provided the actual circuit voltage, transient conditions, temperature, and safety margins are properly evaluated. |
Low Reverse Leakage Current The maximum reverse leakage current is specified at: IR ≤ 5μA at VR = VRRM and Ta = 25°C, according to the supplied specification table. Low reverse leakage is beneficial in high-voltage rectifier circuits because excessive reverse current can increase standby losses and affect the behavior of high-voltage DC circuits. |
|
350mA Forward Current Capability The CL01-12 has an average forward current rating of 350mA. This makes it suitable for medium-current high-voltage rectification applications where both high reverse-voltage capability and continuous forward-current handling are required. The specified 30A IFSM surge forward current provides additional capability for short-duration current surges under the specified test conditions. |
Wide Temperature Capability The CL01-12 has a maximum junction temperature of: Tj = 130°C The supplied specification table gives a temperature range of: -40°C to +130°C This makes the component suitable for many industrial environments where electronic components may experience elevated operating temperatures. Actual thermal performance should always be evaluated according to forward current, mounting conditions, ambient temperature, heat dissipation, and circuit design. |
