MJE 13001 explodes in a GMT-TR20 USB Charger
This transistor comes from a GMT-TR20 USB phone charger which was distributed with the L7, L9 and other phones. After the explosion a trace to the transistor was destroyed and the PCB was blackened. Wire was run to replace the damaged traces and after the transistor was replaced the charger worked again. Credit: http://gushh.net/blog
