Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor, now part of ON Semiconductor, to ensure authenticity. Confirm the specific suffix '10S' corresponds to the standard BD136 variant specifications. Check for RoHS compliance status if required by your manufacturing standards. Ensure the package type matches the SOT-32 footprint on your PCB design. Request the official datasheet from the authorized distributor to validate the electrical parameters against your circuit requirements.

Selection Notes

Select this component when a PNP transistor with 45 V breakdown and 1.5 A current capacity is required in a small surface-mount form factor. Consider the thermal resistance and heat dissipation capabilities of the SOT-32 package for your specific power load. Compare the hFE gain requirements of your application against the minimum specified value. Evaluate the operating temperature range to ensure suitability for your environmental conditions. Verify pinout compatibility with existing designs if replacing a different package style.

Part Context

The BD136 series comprises medium-power NPN and PNP transistors widely used in consumer electronics and industrial control systems. These devices are known for their reliability and cost-effectiveness in low-to-medium power applications. The BD13610S specifically denotes the PNP variant within this family. This series has been a staple in discrete semiconductor markets for decades, offering a balance of performance and availability for various analog and digital switching needs.

Replacement Considerations

Equivalent parts include the MJE13003 or other generic PNP transistors with similar 45V/1.5A ratings. Ensure the replacement package matches SOT-32 dimensions and pinout. Verify that the substitute's thermal characteristics meet the original design's heat dissipation requirements. Check for any differences in gain bandwidth product if used in high-frequency applications.
