BCR48PNE6327BTSA1

Overview

The BCR48PNE6327BTSA1 is a dual digital transistor from Infineon Technologies, configured as an NPN/PNP pair in a PG-SOT363-6 package. It integrates resistors with the transistors to simplify circuit design. Key electrical parameters include a collector-base voltage (V_CBO) of 50 V and a collector-emitter saturation voltage (V_CE(sat)) of 0.3 V maximum. The device features a transition frequency (f_T) of 100 MHz and a minimum current gain (h_FE) of 70. Internal resistor configurations are available with ratios such as R1/R2 = 1 or specific values like 47 kΩ/47 kΩ and 2.2 kΩ/47 kΩ. Power dissipation is rated at 250 mW.

Feature Summary

• Dual configuration combining NPN and PNP transistors for complementary switching applications
• Integrated base resistors reduce component count and simplify biasing networks
• Low saturation voltage ensures efficient switching with minimal power loss
• Surface-mount SOT363 package enables compact PCB layout

Applications

• General-purpose switching circuits requiring complementary logic levels
• Driver stages for LEDs or small loads where space is constrained
• Logic level translation between different voltage domains

Procurement Notes

Verify the exact suffix against official Infineon documentation, as 'E6327BTSA1' may indicate specific tape-and-reel packaging or quality certifications distinct from standard variants. Confirm availability status as some BCR series components have been discontinued or replaced by newer generations. Request FIT reports and material content sheets for compliance verification before integration into production designs.

Selection Notes

Select this component when a matched NPN/PNP pair is required for push-pull or differential switching applications. Ensure the 50 V voltage rating meets the system's peak transient requirements. Verify that the 100 MHz transition frequency is sufficient for the intended switching speed. Compare internal resistor values against the driving source impedance to ensure proper turn-on and turn-off times.

Part Context

This part belongs to Infineon's BCR digital transistor family, which integrates bipolar junction transistors with built-in resistors. These devices are designed to replace discrete transistor-resistor combinations, saving board space and assembly time. The BCR48 variant specifically offers a dual configuration suitable for applications needing both positive and negative switching capabilities in a single footprint.

Replacement Considerations

Check Infineon's product change notification documents for direct replacements if this specific suffix is obsolete. Alternative dual digital transistors from other manufacturers may require external resistor adjustments due to differing internal resistance values.
