Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verify availability through authorized distributors or secondary markets. Confirm that replacement parts meet all original electrical specifications, including voltage ratings and thermal resistance values. Ensure the substitute component supports the required TO-220AC package style and mounting torque specifications for reliable integration into existing designs.

Selection Notes

Select this component for high-voltage rectification tasks requiring fast recovery characteristics. The TO-220AC package facilitates heat dissipation via conduction, suitable for applications where the case temperature remains within operational limits. Consider the 1000 V reverse voltage rating when designing circuits exposed to high transient voltages. Evaluate thermal management requirements based on the 25 W power dissipation rating at a 100°C case temperature.
