2SD2118TLQ

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SD2118TLQ is an NPN silicon epitaxial planar transistor designed for strobe flash applications. It features a low collector-emitter saturation voltage of 0.25V typical at IC/IB = 4A/0.1A and excellent DC current gain characteristics. The device supports a maximum collector current of 5A (DC) and 10A (pulse), with a collector-emitter breakdown voltage of 20V and a transition frequency of 150MHz. Packaged in the CPT3 (TO-252) surface-mount format, it offers high power dissipation capabilities suitable for demanding switching environments.

Single Bipolar Transistors Procurement Notes

Verify the specific 'QR' hFE rank and 'TL' packaging configuration against project requirements before ordering. Confirm that the CPT3 package dimensions align with the target PCB land pattern. Ensure thermal management strategies account for the specified power dissipation limits under actual operating conditions.

Single Bipolar Transistors Selection Notes

Select this component when low saturation voltage is critical for minimizing power loss during high-current pulses. Consider the 2SD2118TLQ for designs requiring robust NPN switching paired with complementary PNP devices from the same series. Evaluate thermal constraints carefully given the high peak current ratings available in the TO-252 package.

Single Bipolar Transistors Part Context

This part belongs to the 2SD2097/2098/2118 family of low VCE(sat) transistors manufactured by ROHM Semiconductor. These components are engineered specifically for strobe flash applications where rapid switching and minimal voltage drop are essential. The family shares similar structural characteristics but varies in packaging and specific electrical rankings.

Single Bipolar Transistors Replacement Considerations

Direct replacements include other members of the 2SD2097/2098/2118 family such as the 2SD2098 or 2SD2097, provided the hFE ranking and package type match the design requirements. Verify pinout compatibility between CPT3 variants before substitution.
