Application Notes
Derating:
The operating case temperature range of the VHB75 series is -40°C to +100°C. When operating the VHB75, proper derating or
cooling is needed. Following is the derating curve of VHB75 without heat sink.
Where:
The power dissapation (Pd) is
Pd= Pi - Po = Po (1-
n )/ n
The thermal resistances are listed below.
The temperature rise (
∆T):
∆T = Pd * Rca
Remote ON/OFF Control
The VHB75 series allows the user to switch the module on and off electronically with the remote on/off feature. The VHB75
series is available with “positive logic” or “negative logic” options.
