Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or official channels. Confirm that the M243 package matches design requirements. Check for ECOPACK compliance if environmental regulations apply. Ensure proper handling due to ESD sensitivity. Review preliminary data status as specifications may change without notice.

Selection Notes

Select based on required frequency range up to 1 GHz and 13.6 V operation. Consider the 40 V drain-source voltage rating for system headroom. Evaluate thermal management needs given the 1.4 °C/W junction-to-case resistance. Verify impedance matching for 945 MHz operation using provided input and load impedance values.

Part Context

The PD85025C belongs to the LdmoST family of lateral MOSFETs designed for RF power amplification. It utilizes ST's LDMOS technology for superior linearity and reliability. The device is housed in the M243 epoxy-sealed package, which is lead-free compliant.

Replacement Considerations
