CTXA-4202S

Diode Arrays Overview

The CTXA-4202S is a fast recovery diode manufactured by Sanken Electric USA Inc. It features a peak repetitive reverse voltage (VRM) of 200 V and an average forward current (IF(AV)) rating of 20 A. The device exhibits a typical forward voltage drop (VF) of 0.90 V at 10 A, with a maximum of 1.2 V. Its reverse recovery time (trr) is typically 18 ns, with a maximum limit of 25 ns under specified test conditions. The component utilizes a TO3P-3L package and offers a thermal resistance (Rth(j-c)) of 2.5 °C/W.

Diode Arrays Procurement Notes

Verify the specific datasheet revision before procurement, as the document indicates this part is not recommended for new designs. Confirm that the TO3P-3L package dimensions and screw torque requirements align with your heatsink mounting specifications. Ensure storage conditions remain within standard temperature and humidity ranges to prevent lead rust or solderability issues prior to assembly.

Diode Arrays Selection Notes

Select this component when designing PFC circuits requiring a 200 V rating and 20 A average current capability. The low thermal resistance makes it suitable for applications demanding efficient heat dissipation. Consider the 25 ns maximum reverse recovery time for switching frequency requirements. Note that the device is marked as not recommended for new designs, so evaluate alternative future-proof options if long-term supply assurance is critical.

Diode Arrays Part Context

The CTXA-4202S belongs to Sanken Electric's portfolio of fast recovery and high-power diodes. It shares functional similarities with other models in the series, such as the CTXS-4202S, which also targets CCM PFC applications.
