2SC4097T106Q

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SC4097T106Q is a medium power NPN silicon epitaxial planar transistor housed in the UMT3 (SOT-323) surface-mount package. It features a collector-emitter voltage of 32V and a maximum continuous collector current of 500mA. The device offers a DC current gain ranging from 120 to 390 depending on the classification rank, with a transition frequency of 250MHz. Absolute maximum ratings include a power dissipation of 200mW at 25°C ambient temperature and a junction temperature limit of 150°C.

Single Bipolar Transistors Feature Summary

• High collector current capability of 500mA for medium power applications
• Low collector-emitter saturation voltage optimized for low voltage operation
• Complements the 2SA1577 PNP transistor for push-pull configurations

Single Bipolar Transistors Applications

• Low frequency amplifiers

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (Q or R) required for your design, as gain ranges differ between classifications. Confirm the T106 taping code matches your automated assembly equipment reel specifications. Ensure the component meets RoHS compliance standards if applicable to your manufacturing requirements. Check for any automotive qualification status if intended for vehicle electronics.

Single Bipolar Transistors Selection Notes

Select this transistor when a compact SOT-323 footprint is needed for medium current switching or amplification. Consider the 32V VCEO rating against your circuit's peak voltage requirements. Evaluate the 200mW power dissipation limit under your expected thermal conditions. Pair with the complementary 2SA1577 for balanced differential or push-pull stages.

Single Bipolar Transistors Part Context

This component belongs to ROHM's general-purpose medium power transistor lineup designed for consumer electronics and industrial control boards. The UMT3 package provides a small form factor suitable for space-constrained printed circuit board layouts. It serves as a standard discrete solution for signal conditioning and load driving tasks in low-to-medium power systems.
