BCR129SE6327HTSA1

Overview

The BCR129SE6327HTSA1 is an NPN silicon digital transistor from the BCR129 series, housed in a SOT-363 surface-mount package. It integrates two internally isolated transistors with good matching characteristics within a single multichip module. The device features a built-in bias resistor (R1) of 10 kΩ and supports a maximum collector-emitter voltage (VCEO) of 50 V. Key electrical parameters include a DC current gain (hFE) ranging from 120 to 630 at IC = 5 mA, a transition frequency (fT) of 150 MHz, and a total power dissipation (Ptot) of 250 mW for the SOT-363 variant. The component is qualified according to AEC-Q101 standards.

Feature Summary

Procurement Notes

Verify the specific ordering suffix E6327HTSA1 against official Infineon documentation to confirm packaging details and RoHS compliance status. Ensure that the SOT-363 package orientation requirements are met during assembly, as the datasheet notes symmetric types may lack defined Pin 1 orientation in the reel. Cross-reference the part number with authorized distributors to confirm current availability and lead times.

Selection Notes

Select this component when dual isolated NPN switching functionality is required in a minimal footprint. The 10 kΩ internal resistor simplifies base drive networks compared to discrete transistors. Consider the 250 mW power dissipation limit and thermal resistance values when designing for high ambient temperatures or continuous duty cycles. Verify compatibility with the target application's voltage and current requirements against the specified maximum ratings.

Part Context

This part belongs to the BCR129 series of NPN silicon digital transistors, which also includes variants like BCR129 (SOT-23) and BCR129W (SOT-323). The 'S' designation specifically indicates the dual-transistor configuration in the SOT-363 package. This series is designed to replace multiple discrete components, reducing board space and assembly complexity in digital logic and interface applications.

Replacement Considerations

Direct replacements must match the dual-isolated NPN configuration and SOT-363 package. Check for equivalent hFE ranges, VCEO ratings, and internal resistor values. Verify AEC-Q101 qualification if automotive reliability is required. Consult manufacturer cross-reference lists for confirmed substitutes.
