Frequently Asked Questions
What is the maximum reverse voltage and forward current rating of the STTH2002CT?
The STTH2002CT supports a maximum reverse voltage of 200 V and a continuous forward current of 30 A, making it suitable for high-power rectification in industrial and consumer power conversion applications.
How fast is the reverse recovery time of STTH2002CT, and why does it matter for switching power supplies?
The STTH2002CT has a reverse recovery time of approximately 25 ns, which is critical in switching power supplies operating above 100 kHz because slower recovery leads to higher switching losses and increased electromagnetic interference.
In which package does the STTH2002CT come, and what thermal performance can be expected?
The STTH2002CT is housed in a TO-220AB through-hole package with a maximum junction temperature of 175°C, allowing effective heat sinking and supporting continuous 30 A operation in demanding power electronics designs.
Can STTH2002CT be used in a 48 V bus PFC stage, and what switching frequency is it optimized for?
Yes, the STTH2002CT is well suited for PFC stages on a 48 V bus; its 25 ns recovery time allows clean operation at switching frequencies up to 150 kHz, minimizing diode-related losses at the required 200 V blocking voltage.
