78H05A

The 78H05A is a kind of positive 3 terminal fixed linear voltage regulator. It is capable of delivering a continuous load current in excess of 5 A at a norminal regulated output voltage of 5 V. Besides, it is available in 2 lead hermetic TO-204MA (formerly called TO-3) package.

There are some features of the 78H05A as follows: (1)5.0 A output current; (2)internal current and thermal overload protection; (3)internal short circuit protection; (4)low dropout voltage (typically 2.3 V @ 5.0 A); (5)50 W power dissipation; (6)metal 2 lead TO-204MA type package.

The following is about the maximum ratings of the 78H05A: (1)input voltage: 40 V; (2)input to output differential, output short circuited: 35 V; (3)internal power dissipation: 50 W @ 25 case; (4)operating junction temperature: 0 to 150 for 78H05ASC (commercial), -55 to +150 for 78H05ASM (mil temp) and -55 to +150 for 78H05ASP (mil process); (5)storage temperature range: -55 to +150; (6)pin temperature (soldering 60 sec): 300.
