BCR 148W H6433

Overview

The BCR 148W H6433 is an NPN Silicon Digital Transistor from the Infineon BCR148 series, housed in a SOT-323 package. It integrates bias resistors R1 and R2, both nominally 47 kΩ with a ratio of 1:1. Key electrical parameters include a collector-emitter breakdown voltage (V(BR)CEO) of 50 V, a maximum collector current (IC) of 100 mA, and a total power dissipation (Ptot) of 250 mW at a case temperature up to 124°C. The device features a transition frequency (fT) of 100 MHz and a DC current gain (hFE) minimum of 70.

Feature Summary

• Integrates dual bias resistors (R1=47 kΩ, R2=47 kΩ) for simplified circuit design
• Qualified according to AEC-Q101 standards for automotive applications
• Provides high switching speed with a transition frequency of 100 MHz
• Offers low saturation voltage and high current gain for efficient signal processing

Applications

• Switching circuits
• Inverter circuits
• Interface driver circuits

Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm the specific suffix H6433 corresponds to the required tape-and-reel packaging format. Ensure compliance with RoHS directives and check for any regional supply restrictions before finalizing procurement plans.

Selection Notes

Select this component when a single NPN digital transistor with integrated 47kΩ bias resistors is required in a compact SOT-323 footprint. Consider the BCR148S variant if two isolated transistors are needed, or the BCR148 for a standard SOT-23 package. Verify thermal constraints against the specified junction-to-solder point resistance.

Part Context

This part belongs to the BCR148 series of NPN silicon digital transistors manufactured by Infineon Technologies. The series includes variants like BCR148 and BCR148S, differing primarily in package type (SOT-23, SOT-323, SOT-363) and internal configuration (single vs. dual transistors). All share similar electrical characteristics but vary in physical dimensions and pinout arrangements.

Replacement Considerations

Direct substitutes within the same family include BCR148E6433HTMA1 (SOT-23) and BCR148SH6327XTSA1 (SOT-363). Cross-brand replacements require matching VCEO, IC, R1/R2 values, and package dimensions. Verify pin compatibility and thermal performance before substitution.
