2SB1188T100Q is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Rohm Semiconductor. Its product description is TRANS PNP 32V 2A MPT3. Review the specifications below when checking this part for your BOM.
The 2SB1188T100Q is a PNP silicon epitaxial planar transistor rated for -32V collector-emitter voltage and -2A continuous collector current. It features a low collector-emitter saturation voltage of -0.5V typical at -2A/-0.2A bias. The device operates with a maximum junction temperature of +150°C and offers a DC current gain (hFE) ranging from 120 to 390 depending on the sub-classification.
Verify the specific hFE bin (QR or QR2) required for your circuit design, as gain ranges vary between 120-270 and 180-390. Confirm package compatibility with ROHM CPT3 or MPT3 standards. Check for RoHS compliance status before finalizing procurement plans.
Select this component when a robust PNP transistor with high current handling (-2A) and low saturation voltage is needed. Ensure the application does not require radiation tolerance or extreme reliability levels associated with aerospace or medical systems. Verify thermal management capabilities for the intended operating environment.
This part belongs to the 2SB1188/1182/1240 family of medium power transistors manufactured by ROHM Semiconductor. It serves as a complement to NPN types like the 2SD1766 and 2SD1758. The T100 suffix indicates tape and reel packaging with a quantity of 1000 units per reel.
Direct substitutes include the 2SB1182 and 2SB1240 within the same ROHM family. Complementary NPN replacements are the 2SD1766, 2SD1758, and 2SD1862.
