API Delevan recommends a 4-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended for the top and bottom layers. Additionally, a thermal pad on the bottom of the device should be connected to a heat sink or a thermal management system.
The PT500-2000 requires a bias voltage of 15V to 30V, and a bias current of 1mA to 10mA. The recommended bias circuit includes a voltage regulator, a current-limiting resistor, and a decoupling capacitor. API Delevan provides a reference design for biasing in their application notes.
The PT500-2000 is rated for a maximum power handling of 2000W, but this can be affected by factors such as operating frequency, duty cycle, and ambient temperature. API Delevan recommends derating the power handling by 20% to ensure reliable operation.
API Delevan recommends using overvoltage protection (OVP) and overcurrent protection (OCP) circuits to prevent damage to the device. These circuits can be implemented using voltage supervisors, current sense resistors, and protection ICs.
The PT500-2000 is a sensitive electronic component and requires proper storage and handling to prevent damage. API Delevan recommends storing the device in a dry, cool place, away from direct sunlight and moisture. Handling should be done with anti-static wrist straps and mats to prevent electrostatic discharge (ESD) damage.
