Overview
The SD1019-02 is an NPN silicon RF power transistor designed for VHF applications. It operates within the 136 MHz band with a 13.5 V common emitter configuration. Key electrical parameters include a minimum output power (P_OUT) of 30 W and a gain of 4.5 dB. Absolute maximum ratings at T_case = 25°C specify a collector-base voltage (V_CBO) of 65 V, collector-emitter voltage (V_CEO) of 35 V, and emitter-base voltage (V_EBO) of 20 V. The device utilizes nichrome aluminum metallization to achieve infinite VSWR at rated operating conditions.
Feature Summary
- Designed primarily for VHF communications using epitaxial silicon NPN planar technology.
- Utilizes nichrome aluminum metallization to ensure infinite VSWR at rated operating conditions.
Applications
- VHF communications systems
- RF and microwave transistor circuits
Procurement Notes
Verify the manufacturer designation carefully, as the SD1019 part number appears across multiple vendors including Microsemi Corporation and Advanced Semiconductor. Confirm that the specific suffix '-02' aligns with your required datasheet revision and electrical specifications before procurement. Cross-reference the official component document to ensure compatibility with your circuit design requirements.
Selection Notes
Select this component for VHF band operations requiring high output power. Ensure thermal management supports the total power dissipation limits defined in the absolute maximum ratings. Verify that the operating voltage remains within the 35 V collector-emitter limit and that the frequency range matches the 136 MHz design target.
Part Context
The SD1019 series belongs to the RF and Microwave Transistors category, specifically optimized for VHF applications. This family includes variants such as SD1019-02, SD1019-2, and SD1019-5 from Advanced Semiconductor, and standard SD1019 units from Microsemi Corporation. These transistors share similar structural designs for VHF communication use cases.
Replacement Considerations
Potential substitutes include the SD1480 from STMicroelectronics or other VHF RF transistors like the MS1252, MS1401, and SD1224-02 from Advanced Power Technology. Verify pinout compatibility and electrical parameter equivalence before substitution.
