JANSM2N3439L is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is TRANS NPN 350V 1A TO-5AA. Review the specifications below when checking this part for your BOM.
The JANSM2N3439L is a silicon NPN power bipolar junction transistor (BJT) manufactured by Microchip Technology. Designed for high-voltage applications, this component features a collector-emitter voltage rating of 350V and a continuous collector current capacity of 1A. The device dissipates up to 800mW of power and is housed in a surface-mount package. It belongs to the RH Power BJT sub-category within the broader class of bipolar transistors.
Verify the specific suffix configuration against the official Microchip datasheet to ensure compatibility with required radiation hardness or military specifications. Confirm that the ordering information matches the exact electrical parameters needed for the target design. Cross-reference the manufacturer's latest product change notifications to account for any recent manufacturing updates or material changes that may affect integration.
Select this component when the design requires a robust NPN transistor capable of handling 350V potentials in a surface-mount form factor. Ensure the thermal management strategy accommodates the 800mW power dissipation limit under maximum load conditions. Compare against through-hole alternatives if higher current ratings or different mounting constraints are present in the system architecture.
This part is part of Microchip's portfolio of discrete semiconductors, specifically within the bipolar junction transistor category. It shares core electrical specifications with other variants in the 2N3439 series but differs in packaging and potential qualification levels. The JAN prefix typically indicates a specific quality or screening level defined by the manufacturer for specialized electronic components.
Direct substitutes include the JANTX2N3439P and JANTXV2N3439U4, which share identical 350V/1A ratings. Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit within the existing footprint.
The maximum collector-emitter voltage rating is 350V.
No, the JANSM2N3439L variant is specified as a surface-mount device (SMD/SMT).
The JANSM2N3439L utilizes silicon (Si) technology.
