STMICROELECTRONICS STTH1212D Standard Power Diode, 1.2 kV, 12 A, Single, 590 mV, 50 ns, 100 AThe STTH1212D is an ultrafast Soft Recovery Diode with high reverse voltage capability. The high quality design of this diode has produced a device with low leakage current, regularly reproducible characteristics and intrinsic ruggedness. These characteristics make it ideal for heavy duty applications that demand long term reliability. The improved performance in low leakage current and therefore thermal runaway guard band, is an immediate competitive
The STTH1212D is an ultrafast Soft Recovery Diode with high reverse voltage capability. The high quality design of this diode has produced a device with low leakage current, regularly reproducible characteristics and intrinsic ruggedness. These characteristics make it ideal for heavy-duty applications that demand long term reliability. The improved performance in low leakage current and therefore thermal runaway guard band, is an immediate competitive advantage for this device.
- Very low conduction and switching losses
- High frequency and high pulsed current operation
- High junction temperature
- 30A RMS forward current
- 1.6�C/W Junction to case thermal resistance
Applications
Power Management, Industrial, Motor Drive & Control

Great room divider.
Color: White, Size: 3 Panel Standard
This is a game changer. I use this when I have a lot of guests sleeping over. it divides my offer for privacy. I wouldn't be able to use a tension rod and curtain so this does the job. it divides a huge space area.

Lightweight and Easy-to-Assemble
Color: Black, Size: 3 Panel Standard
These privacy screens are three separate panels, which is really convenient if you don’t need to use all of them at once. I’m currently using two to section off part of my craft room for storage, and it’s working perfectly.
They’re lightweight and super easy to move around, so I can rearrange my space whenever I need to. Assembly was simple—everything went together quickly without any hassle.

Great for Privacy, Just a Little Flimsy
Color: Black, Size: 3 Panel Standard
I recently got this room divider to create a bit more privacy in my home office, and it's been really handy. The thick polyester fabric helps block out distractions, and it's great that it's waterproof, so no worries about spills messing it up. The metal feet keep it stable enough, though I've noticed it can feel a bit wobbly if bumped. It's also super easy to fold and store when not in use, which is a huge plus if you have limited space like I do. Overall, it’s a practical addition, though handling it gently might be a good idea.
