摘要： A semiconductor laser device has a cathode grounded and an anode connected to a collector of a transistor. The transistor has an emitter grounded and a base connected to a first external terminal via a first resistor. A digital transistor has a collector connected to the base of the transistor, an emitter grounded, and a base connected to a second external terminal via a resistor. When a voltage equal to or higher than the predetermined first voltage is applied to the base of the transistor, the transistor is put into a conducting state, and the semiconductor laser device is grounded via the transistor and thereby protected from static electricity and leak current.

摘要： The tip end of the bonding tip is defined between first and second edges. A first inclined surface gets remoter from a first terminal at a position remoter from the first edge. The second inclined surface likewise gets remoter from the first terminal at a position remoter from the second edge. The solder is contoured by first and second contours on the first terminal. The second terminal is located on the solder between the first and second contours. The tip end of the bonding tip is urged against the second terminal. Heat is transferred from the bonding tip to the solder. The melted solder spreads into gaps between the second terminal and the first and second inclined surfaces. The solder is thus prevented from spreading outside the contour of the first terminal. This results in a reliable avoidance of a short circuit between the adjacent first terminals.
