Sony: PS Vita sells 1.2 million units more than expected

Sony: PS Vita sells 1.2 million units worldwide March 1 news, according to foreign media reports, Sony recently stated that since the launch of the PlayStaion Vita has reached 1.2 million units worldwide sales, exceeding expectations.

In December 2011, Vita was first sold in Japan and other Asian markets. Last week, Vita began listing in North America, Latin America, Europe and other regions. Sony did not disclose sales figures for various regions, so it was not clear that sales in the first week of listing.

Sony also announced that 2 million copies of the game have been sold for PS Vita.

On the other hand, Sony's competitor Nintendo 3DS sold 1.5 million units in December last year, but this figure did not reach expectations.

When the semiconductor diode is turned on, it is equivalent to the switch closing (circuit is turned on), and when it is turned off, it is equivalent to the switch opening (circuit cut), so the diode can be used for switching, and the commonly used model is 1N4148. Since the semiconductor diode has a unidirectional conduction characteristic, the PN junction is turned on under a positive bias, and the resistance in the on state is small, about several tens to several hundreds of ohms; in the reverse bias, it is off. The resistance is very large. Generally, the silicon diode is above 10 Μ Ω, and the bismuth tube is also several tens of kilo ohms to several hundred kilo ohms. With this feature, the diode will act as a control for the current to turn on or off in the circuit, making it an ideal electronic switch.
