Any remaining inventory is limited to existing stock in the distribution channel, and procurement should plan for a last-time-buy or a qualified replacement. ## 20 ns reverse recovery — the switching parameter that defines the part The 20 ns trr means the diode turns off quickly, reducing switching losses. ## 4 A per diode, common-cathode pair — load sharing in a single package Each diode in the common-cathode pair is rated for 4 A average rectified current. The forward voltage drop is 1.1 V at 4 A. ## Package and mounting — TO-220-3 through-hole The three leads are the two anodes and the common cathode tab. For high-reliability or vibration-prone environments, consider adding a dab of adhesive under the body or a through-hole staking compound.","metaTitle":"STTH802CT Fast Recovery Diode, 200 V, 4 A, TO-220-3","metaDescription":"STTH802CT fast recovery diode, 200 V reverse, 4 A per diode, 20 ns trr, TO-220-3 common cathode pair.
