- High 400 V reverse voltage capability for robust high-voltage rectification in industrial and power conversion designs
- Dual-anode common-cathode configuration in TO-247 package enables compact, high-current bridge or center-tap rectifier layouts
Applications
STTH100W04CW is designed for high-voltage, high-current rectification in industrial power supplies, motor drive inverters, and UPS systems. Its ultra-fast soft recovery makes it well-suited for switch-mode power supply output stages and free-wheeling diode applications where low EMI is critical. The common-cathode dual configuration simplifies PCB layout in full-bridge rectifier and synchronous rectification circuits operating up to 400 V.

Frequently Asked Questions
What is the maximum forward voltage of STTH100W04CW under full load?
The STTH100W04CW has a maximum forward voltage (VF) of 1.75 V at rated current, measured under standard test conditions. This low conduction drop helps reduce power dissipation in high-current 100 A rectifier stages across industrial and power supply applications.
How does the soft recovery factor of STTH100W04CW benefit switch-mode power supply designs?
With a soft factor of 0.3, the STTH100W04CW produces a gradual reverse-recovery current waveform rather than an abrupt snap-off, significantly reducing voltage spikes and EMI in switch-mode power supplies operating above 10 kHz. This allows designers to use smaller snubber networks and simplify EMI filtering in 400 V bus systems.
Which package does STTH100W04CW use, and what are its thermal advantages for a 100 A design?
STTH100W04CW is housed in a TO-247 (JEDEC R-PSFM-T3) through-hole package, which provides a large copper lead frame and exposed tab for direct heatsink mounting. This enables efficient thermal dissipation when handling 100 A continuous forward current in industrial rectifier and inverter stages where junction temperature management is critical.
In which high-voltage rectifier topologies can STTH100W04CW replace slower recovery diodes?
STTH100W04CW can replace standard recovery rectifiers in full-bridge, center-tap, and boost converter topologies at voltages up to 400 V. Its ultra-fast recovery time reduces switching losses at frequencies above 20 kHz, making it a direct upgrade in motor drive output stages, PFC boost stages, and UPS inverter circuits where conventional 1 µs recovery diodes generate excessive losses.
