BCR148WH6327XTSA1

Overview

The BCR148WH6327XTSA1 is an NPN silicon digital transistor from the Infineon BCR148 series, housed in a SOT-323 surface-mount package. It integrates two bias resistors with nominal values of 47 kΩ each (R1 and R2). The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Total power dissipation is rated at 250 mW with a junction temperature limit of 150 °C. Key electrical characteristics include a DC current gain (hFE) of 70 minimum, a transition frequency (fT) of 100 MHz, and a collector-base cutoff current (ICBO) of 100 nA maximum.

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number against official datasheets. Confirm that the ordering suffix matches the required SOT-323 package configuration. Ensure compliance with automotive quality standards if deployed in vehicle systems. Validate thermal resistance parameters against specific PCB layout conditions to maintain safe operating temperatures.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for low-power switching tasks. The SOT-323 package suits space-constrained designs. Verify that the 50 V voltage rating and 100 mA current capacity align with the target application's load requirements. Consider the 250 mW power dissipation limit relative to ambient thermal conditions.

Part Context

This component belongs to the BCR148 series of NPN silicon digital transistors manufactured by Infineon Technologies. The series includes variants such as BCR148S and BCR148W, which differ primarily in package type and internal transistor configuration. The BCR148W specifically utilizes the SOT-323 form factor, distinguishing it from the dual-transistor SOT363 (BCR148S) and standard SOT23 (BCR148) versions.

Replacement Considerations

Direct substitutes within the same family include BCR148SH6327XTSA1 and BCR148H6327XTSA1. These alternatives share identical electrical specifications but utilize different packages (SOT363 and SOT23, respectively). Pinout compatibility must be verified before substitution due to physical footprint differences.
