Richardson RFPD announces new 50 V moisture-resistant DMOS transistor from ST
Richardson RFPD Inc. announces immediate availability and full design support capabilities for a new diffused metal oxide semiconductor (DMOS) transistor from STMicroelectronics (ST).
The SD4933MR is an N-channel field-effect RF power transistor intended for use in 50V industrial, scientific and medical (ISM) applications up to 100 MHz. The device benefits from the latest generation of environmentally-designed packaging and is ruggedized against cyclic high-moisture operating and severe storage conditions.
Key features of the SD4933MR include:
- POUT = 300 W minimum with 24 dB gain @ 30 MHz
- Moisture-resistant package for extreme environments
- Improved ruggedness V(BR)DSS > 200V
- 20:1 all phases load mismatch capability under CW conditions
- Same footprint as SD4933
- Excellent thermal stability
- 200 °C maximum junction temperature
- Passes THB 85/85 reliability test
