Frequently Asked Questions
What is the maximum repetitive reverse voltage the STTH2002DI can block in a switching power supply?
The STTH2002DI is rated for a maximum repetitive reverse voltage of 200 V, making it suitable for rectification stages in offline power supplies operating from 85 V to 132 V AC mains. Combined with its 20 A average forward current capability, it handles typical 100 W to 300 W converter designs without requiring external voltage-snubber circuits.
How does the ultra-fast recovery time of the STTH2002DI reduce losses in a motor drive freewheeling application?
In freewheeling diode duty, a slower recovery diode conducts a reverse current spike each time the motor switch turns on, dissipating extra energy as heat. The STTH2002DI ultra-fast recovery characteristic minimizes this reverse-recovery charge, reducing switching losses at the 20 A operating point and allowing the inverter to run at higher frequencies above 20 kHz without excessive diode heating.
What forward voltage drop should be expected when the STTH2002DI conducts 20 A in a high-current rectifier stage?
At full 20 A forward current, the STTH2002DI exhibits a maximum forward voltage of 0.95 V. This results in a worst-case conduction power loss of 19 W at full load, which the TO-220AC package can dissipate efficiently when mounted to a suitable heatsink with appropriate thermal interface material, keeping junction temperatures well within the rated maximum.
