Frequently Asked Questions

What are the current and voltage ratings of the STTH20W02CW, and how do they suit high-power designs?

The STTH20W02CW is rated for 20 A continuous forward current and 200 V reverse blocking voltage, with a non-repetitive peak forward current of 80 A and a maximum forward voltage of 1.4 V at rated current. These ratings make it suitable for high-power rectification in switch-mode power supplies and motor drive circuits that demand low conduction losses and reliable surge handling.

What advantage does the common cathode dual configuration offer in SMPS or inverter designs?

The common cathode dual configuration of the STTH20W02CW allows both diode elements to share a single cathode terminal, directly enabling center-tap rectifier circuits without external bussing. This simplifies PCB layout and reduces component count in output-stage designs for SMPS and inverters, while the TO-247 package provides low thermal resistance for heat sinking at 20 A operation.

How does the ultra-fast recovery characteristic of the STTH20W02CW reduce losses in high-frequency power converters?

Ultra-fast recovery diodes like the STTH20W02CW have a short reverse recovery time, which reduces the charge stored in the junction that must be swept out during turn-off. In high-frequency power converters operating above 50 kHz, this shorter recovery time directly lowers switching losses and reduces EMI, improving overall efficiency and thermal performance compared to standard recovery rectifiers at 200 V and 20 A.
