Procurement Notes
Verify the specific manufacturer source, as the 2N5492 specification is utilized by multiple vendors including Central Semiconductor and Savantic. Confirm that the received component matches the TO-220-3 flange mount package and NPN polarity. Ensure the datasheet aligns with the required 55V breakdown and 7A current ratings before integration into the final assembly.
Selection Notes
Select this component for designs requiring moderate power amplification or switching within a 55V limit. The TO-220 package facilitates heat sinking via the metal tab. Consider the 800kHz transition frequency when evaluating high-speed switching requirements against lower-frequency linear amplifier needs.
Part Context
The 2N5492 is a standard military-style NPN power transistor designation. While originally associated with Harris Corporation specifications, the part number is widely distributed by various semiconductor manufacturers such as Central Semiconductor Corp. and Savantic, Inc., often maintaining consistent electrical characteristics across different production sources.
Replacement Considerations
Cross-reference with other NPN power transistors in the TO-220 package offering similar V(BR)CEO and I(C) ratings. Verify pinout compatibility and thermal resistance values when substituting with parts from different manufacturers.
