Overview
The SD4933MR is an N-channel DMOS RF power transistor designed for ISM applications up to 100 MHz. It operates at a drain-source voltage of 50 V with a breakdown voltage (V(BR)DSS) of 200 V. The device delivers a minimum output power (P_OUT) of 300 W with a gain of 24 dB at 30 MHz. It features a moisture-resistant package suitable for extreme environments and offers a 20:1 all-phase load mismatch capability.
Feature Summary
- Moisture resistant package engineered for cyclic high moisture operation and severe storage conditions
- High ruggedness with 20:1 all phases load mismatch capability
- Excellent thermal stability
Applications
- Industrial, Scientific, and Medical (ISM) applications
- HF/VHF radio frequency power amplification
Procurement Notes
Verify the specific ordering suffix and package variant against the manufacturer's current datasheet before procurement. Confirm RoHS compliance status and environmental directives alignment. Check availability through authorized distributors as supply levels fluctuate. Ensure the component grade matches industrial requirements. Validate that the M177MR package form factor fits the target PCB layout constraints.
Selection Notes
Select this component for designs requiring high power output in the HF/VHF range. Ensure the operating frequency remains within the 100 MHz limit. Verify that the system can handle the 200 V breakdown voltage margin. Consider the thermal management needs associated with 300 W output power. Confirm compatibility with 50 V supply rails typical for ISM band equipment.
Part Context
The SD4933MR belongs to STMicroelectronics' family of RF MOSFET transistors. It is part of the broader SD4933 series, which includes variants like the SD4933. These devices are specifically engineered for robust performance in demanding radio frequency environments, emphasizing durability and power efficiency.
Replacement Considerations
The SD4933 is a closely related variant within the same product family. Verify pinout compatibility and electrical parameter equivalence before substitution. Consult official replacement lists for confirmed cross-references.
