I am working on some Thermal Analysis for our project, and we are moving along OK. But I am looking for some Temp Parameters, could you please validate and/or provide the Theta JA, Theta JC, Max Junction Temp, Operating Temp Range, and Junction Temp Range.
MFG PN | Description | Θ JA | Θ JC | Max Tj | Operating Temp | Junction Temp |
BAT720 | DIODE SMT ZHCS500 SCH 40V 500MA | 220 | 125 | -40°C to +125°C | 125 | |
BZV55-B2V4,115 | DIODE ZENER 2.4V 500MW LLDS | 380 | 300 | 200 | UNKNOWN | -65°C to +200°C |
According to the BAT720 Datasheet http://cache.nxp.com/documents/data_sheet/BAT720.pdf
Section 5. Limiting values - Tamb=Tj is -55 +125 C
Section 6. Thermal characteristics - Rth(j-a) - thermal resistance from junction to ambient in free air = 500 K/W
According to the BZV55 Datasheet http://cache.nxp.com/documents/data_sheet/BZV55_SER.pdf
Section 5. Limiting values - Tj junction temperature -65 +200 C
Section 6. Thermal characteristics
Rth(j-a) - thermal resistance from junction to ambient in free air = 380 K/W
Rth(j-sp) - thermal resistance from junction to solder point = 300 K/W
Have a great day,
Andrei
