SPA13003-S-AC is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists onsemi. Its product description is BIP NPN 1A 400V. Review the specifications below when checking this part for your BOM.
The SPA13003-S-AC is a high-voltage, fast-switching NPN power transistor manufactured by onsemi. It utilizes high voltage Multi Epitaxial Planar technology to achieve high switching speeds and medium voltage capability. The device employs a Cellular Emitter structure with planar edge termination to enhance switching performance while maintaining a wide Reverse Biased Safe Operating Area (RBSOA). Designed for lighting applications and low-cost switch-mode power supplies, it offers very high switching speed and low spread of dynamic parameters for reliable operation.
Verify the specific suffix 'S-AC' against official datasheets to confirm package type and pinout configuration, as variations exist within the 13003 family. Confirm RoHS compliance status and check for end-of-life notifications or alternative part recommendations from onsemi before finalizing procurement plans.
Select this component when high switching speed and medium voltage capability are required in compact designs. The Cellular Emitter structure makes it suitable for applications demanding fast turn-on and turn-off times. Ensure the thermal management design accommodates the specific package's thermal resistance characteristics for the intended power dissipation levels.
This part belongs to the 13003 series of high-voltage NPN power transistors. Similar variants include STD13003 and ST13003-K, which share core technological features like Multi Epitaxial Planar construction but may differ in packaging options such as IPAK or DPAK. The series is generally targeted at efficient, cost-effective power switching solutions.
Cross-reference with other 13003 series parts like STD13003 or MJE13003. Verify that the replacement matches the required voltage rating, current handling, and package footprint. Note that some alternatives may offer different switching speeds or safe operating area characteristics.
