Fast recovery diode for PFC and output rectification
The STMicroelectronics STTH30AC06CP is a 600 V, 15 A per diode fast-recovery rectifier in a common-cathode pair configuration, housed in a through-hole TO-3PF package. The wide junction temperature range from -65°C to 175°C covers industrial and automotive environments with high thermal cycling.
In a 100 kHz PFC boost stage, the fast recovery characteristic limits the current tail that would otherwise heat the diode and the companion MOSFET. The forward voltage drop is 1.95 V at 15 A, a trade-off that accepts a moderate conduction loss for the speed gain. The 10 µA reverse leakage at 600 V rated voltage is typical for this class of fast epitaxial diode.
The STTH30AC06CP is marked obsolete by STMicroelectronics.
