15 March 2013 Question by: Rapid Customer | Product code: 81-0441
Q. (also 81-0442) Puzzled by datasheets, two different manufacturers. Both devices have two different power ratings, spread across two datasheet columns. I'll take the smaller, but what does it mean? Power dissipation at Tc = 25°C PD 625 mW Derate above 25°C 5.0 mW/°C then on the next row, Power dissipation at Tc = 25°C PD 1.5 W Derate above 25°C 12 mW/°C
A. Hi Matthew. Thank you for your question. Basically this is the amount of power the case will dissipate dependent on the temperature it is running at. The calculation is based on an average of 25 deg but shows to average power at set temperatures: Power dissipation at Tc = 25°C Derate above 25°C PD 625 mW 5.0 mW/°C Power dissipation at Tc = 25°C Derate above 25°C PD 1.5 W 12 mW/°C

31 March 2012 Question by: Rapid Customer | Product code: 81-0441
Q. bc549c does not appear in the technical spec area. I need to know if it is TO 92 a,b or c, quite important.
A. HI Max, the bc549C unit is a TO92 and the unit is a C type
