BCR148WE6327BTSA1

Overview

The Infineon BCR148WE6327BTSA1 is an NPN Silicon Digital Transistor 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 ratings include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a total power dissipation (Ptot) of 250 mW at case temperatures up to 124°C. The device features a DC current gain (hFE) minimum of 70 at IC = 5 mA and a transition frequency (fT) of 100 MHz. It operates within a junction temperature range of -65°C to +150°C and complies with AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates dual bias resistors (R1=47kΩ, R2=47kΩ) for simplified circuit design
• Automotive qualified according to AEC-Q101 standards
• High switching speed with a transition frequency of 100 MHz
• Low saturation voltage for efficient signal inversion

Applications

• Switching circuits
• Inverter applications
• Interface driver circuits

Procurement Notes

Verify the specific ordering suffix 'E6327BTSA1' against official Infineon documentation to confirm tape-and-reel specifications and marking codes. Ensure component authenticity through authorized distribution channels. Confirm RoHS compliance status as indicated in the datasheet before final procurement integration.

Selection Notes

Select this component when a single NPN digital transistor with integrated 47kΩ bias resistors is required. The SOT-323 package suits space-constrained designs. Verify that the 50V VCEO rating meets the application's voltage requirements and that the 100mA current capacity is sufficient for the load.

Part Context

This part belongs to the BCR148 series of NPN silicon digital transistors from Infineon Technologies. The series includes variants like BCR148S (dual transistor in SOT-363) and standard BCR148 (SOT-23). The BCR148WE6327BTSA1 specifically denotes the SOT-323 package variant within this family.

Replacement Considerations

Direct substitutes within the same series include BCR148WH6327XTSA1. Cross-package equivalents such as BCR148B6327HTSA1 (SOT-23) may be considered if pinout compatibility allows.
