2.2kV Transistor with Innovative Package

We often hear about applications where a high voltage transistor would be useful. STMicroelectronics has recently introduced a 2.2kV transistor. It's a hybrid emitter switched bipolar transistor. There are several parts in this family including the 2.2kV, 3A
STC03DE220HV.

As if the voltage rating wasn't enough, what makes it especially interesting is a notch between the collector pin and the other pins in the TO-247 type package. The notch serves to increase the creepage voltage (see glossary at http://www.highvoltageinfo.com/glossary.php) to permit the part to operate at higher voltage than a typical TO-247 device.

For more information, see the spec sheet at http://www.st.com/stonline/products/literature/ds/12919.pdf
