BCR133WH6327XTSA1

Overview

The Infineon BCR133WH6327XTSA1 is an NPN silicon digital transistor housed in a SOT-323 surface-mount package. It integrates a single transistor with two internal bias resistors, specifically R1 and R2, both nominally rated at 10 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Electrical characteristics include a DC current gain (hFE) minimum of 30 at IC = 5 mA, and a transition frequency (fT) typical value of 130 MHz at IC = 10 mA. Total power dissipation is rated at 250 mW for the SOT-323 variant. The component operates within a junction temperature range of -65 °C to +150 °C and complies with AEC-Q101 qualification standards.

Feature Summary

• Integrates an NPN transistor with dual built-in bias resistors (R1=10kΩ, R2=10kΩ) to simplify circuit design
• Provides high-speed switching capability with a typical transition frequency of 130 MHz
• Features robust thermal performance with a total power dissipation rating of 250 mW in the SOT-323 package
• Qualified according to AEC-Q101 automotive standards for reliability

Applications

• Switching circuits requiring integrated base drive
• Inverter logic applications
• Interface circuits between different logic families
• Drive circuits for low-power loads

Procurement Notes

Verify the specific suffix WH6327XTSA1 against official Infineon documentation to confirm the exact tape-and-reel packaging configuration and RoHS compliance status. Ensure that the ordering code matches the required SOT-323 variant, as other suffixes may indicate different packages like SOT-23 or SOT-363. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a compact NPN digital transistor with matched internal bias resistors is required. The 10 kΩ resistor ratio suits general-purpose switching and interface tasks. Consider the 50 V breakdown voltage and 100 mA current limit for load requirements. The SOT-323 package offers a small footprint suitable for space-constrained designs. Verify thermal constraints if operating near the maximum power dissipation limit.

Part Context

The BCR133 series includes variants such as BCR133 (SOT-23), BCR133S (SOT-363, dual isolated transistors), and BCR133W (SOT-323). The 'W' designation typically corresponds to the SOT-323 package. All variants share similar electrical characteristics but differ in pinout and physical dimensions. This specific model represents the single-transistor version in the compact SOT-323 form factor.

Replacement Considerations

Direct substitutes within the same family include BCR133 (SOT-23) and BCR133W (SOT-323). Note that BCR133S contains two isolated transistors and has a different pinout. When replacing, ensure the new component matches the 10 kΩ resistor values and the 50 V/100 mA ratings. Verify package compatibility for PCB mounting.
