2N656S is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is TRANS NPN 60V 12A TO-5AA. Review the specifications below when checking this part for your BOM.
The Microchip Technology 2N656S is an NPN silicon planar bipolar junction transistor housed in a TO-5AA metal can package. It features a collector-emitter breakdown voltage of 60 V and a maximum continuous collector current of 12 A. The device is rated for 4 W power dissipation with a base current capability of 0.5 mA. Operating junction temperature ranges from -65°C to 200°C, supporting robust performance in demanding environments.
Verify the specific suffix 'S' against official Microchip documentation to confirm package type and lead configuration. Ensure the procurement source provides valid traceability for the TO-5AA metal can format. Cross-reference the manufacturer part number with the latest datasheet revision to confirm electrical parameters match the required design specifications.
Select this component when high current handling up to 12 A is required alongside moderate voltage ratings. The wide operating temperature range makes it suitable for industrial or military contexts. Consider the through-hole TO-5AA package constraints during PCB layout planning to ensure proper thermal management and mechanical stability.
This transistor belongs to the family of NPN silicon annular transistors originally developed for general-purpose and switching uses. The 2N656 designation represents the standard variant, while the 2N656S specifies the particular packaging and lead style offered by Microchip Technology for integration into legacy and modern electronic systems.
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with original Raytheon or Motorola equivalents only if explicitly supported by manufacturer cross-reference lists.
