2SB1181TLP

Single Bipolar Transistors Overview

The 2SB1181TLP is a PNP silicon power bipolar junction transistor manufactured by ROHM Semiconductor. It features a maximum collector current of 1.0 A and a collector-emitter breakdown voltage of 80 V. The device is housed in a CPT3 surface-mount package, which corresponds to the SC-63 form factor. Key electrical characteristics include a minimum DC current gain (hFE) of 120 and a maximum collector-emitter saturation voltage of 0.4 V under specified test conditions. The component supports a maximum operating junction temperature of 150 °C.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage for efficient switching performance
• Complementary pairing with specific NPN types such as 2SD1898 and 2SD1733
• Designed for suitability in middle power driver applications

Single Bipolar Transistors Applications

• Middle power driver circuits
• Complementary amplifier stages paired with 2SD1898 or 2SD1733

Single Bipolar Transistors Procurement Notes

Verify the exact suffix against official ROHM documentation to confirm packaging and tape specifications. Confirm RoHS compliance status and lead-free certification requirements for your assembly process. Check for any design-in restrictions or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when an 80V PNP transistor with 1A continuous current capability is required. Ensure the application demands a low saturation voltage around 0.4V. Verify that the CPT3/SC-63 package fits the PCB layout constraints. Consider the complementary 2SD1898 or 2SD1733 if a matched pair is needed for push-pull configurations.

Single Bipolar Transistors Part Context

This part belongs to ROHM's middle power transistor series, designed for general-purpose switching and amplification. It serves as the PNP counterpart to the 2SD1898 and 2SD1733 NPN transistors. The CPT3 package provides a compact solution for surface-mount designs requiring moderate power handling capabilities within standard industrial and consumer electronics applications.

Single Bipolar Transistors Replacement Considerations

Official complementary substitutes include the 2SD1898 and 2SD1733 NPN transistors for matched pairs. Direct replacements should match the 80V, 1A, and CPT3 package specifications. Verify pinout compatibility and thermal characteristics before substituting.
