Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix LXHF corresponds to the correct packaging and marking requirements for your assembly process. Confirm the specific hFE binning (Y rank: 120 to 240) matches your circuit's gain requirements. Ensure compliance with the intended use restrictions outlined in the datasheet, particularly regarding automotive or unintended applications if applicable.

Single Bipolar Transistors Selection Notes

Select this component when a small-form-factor NPN transistor with moderate voltage ratings and high current gain is required. The Y rank provides a guaranteed minimum gain of 120, suitable for general-purpose amplification. Consider the 120 mW power dissipation limit and the 150 °C junction temperature rating when designing thermal management solutions for the SSM package.

Single Bipolar Transistors Part Context

This part belongs to the 2SC4738 series of silicon NPN epitaxial transistors. It is complementary to the 2SA1832 PNP transistor. The series includes variants with different hFE classifications (Y, GR, BL) and packaging options (LF, LXGF, LXHF). The LXHF suffix denotes a specific tape-and-reel packaging configuration for automated assembly.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same family include 2SC4738-GR,LXHF and 2SC4738-BL,LXHF, which share identical electrical ratings but differ in hFE gain bins. Verify pinout compatibility and package dimensions (SSM/SOT-416) before substitution.
