2SA1952TLQ

Single Bipolar Transistors Overview

The ROHM 2SA1952TLQ is a PNP high-speed switching transistor housed in the CPT3 surface-mount package. It supports a collector current of −5A and a collector-emitter voltage of −60V, with a power dissipation rating of 1W at 25°C. Key electrical characteristics include a typical fall time of 0.15µs at −3A and a low saturation voltage of −0.2V at IC/IB = −3/−0.15A. The device features a wide safe operating area and a transition frequency up to 130MHz.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix TLQ against official ROHM documentation to confirm packaging details and reel specifications. Ensure compatibility with the CPT3 footprint dimensions provided in the datasheet. Confirm that the −60V rating aligns with your circuit's maximum voltage requirements. Check for any RoHS compliance statements in the latest product release notes.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with high-speed switching characteristics and moderate current handling is required. It serves as a complement to the 2SC5103 NPN transistor. Consider the CPT3 package size for PCB layout constraints. Evaluate the thermal management needs given the 1W power dissipation limit at 25°C ambient temperature.

Single Bipolar Transistors Part Context

The 2SA1952 series consists of PNP silicon epitaxial planar transistors designed for high-speed switching applications. The TLQ suffix indicates a specific tape-and-reel packaging format suitable for automated assembly. This component belongs to ROHM's general-purpose transistor lineup, optimized for low saturation voltage and fast transient response.

Single Bipolar Transistors Replacement Considerations

The datasheet explicitly states that the 2SA1952 complements the 2SC5103. Verify pinout compatibility and electrical parameters before substituting with other PNP transistors from different manufacturers. Ensure the replacement part meets or exceeds the −60V VCEO and −5A IC ratings.
