BCR148SE6327BTSA1

Overview

The BCR148SE6327BTSA1 is an NPN silicon digital transistor from the BCR148 series, featuring two internally isolated transistors within a single SOT-363 multichip package. It integrates bias resistors of 47 kΩ each (R1 and R2) with a typical ratio of 1. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 70, a transition frequency (fT) of 100 MHz, and a total power dissipation of 250 mW at a case temperature up to 115°C. It operates within a junction temperature range of -65°C to 150°C.

Procurement Notes

Verify the specific suffix 'E6327BTSA1' against official Infineon documentation to confirm reel orientation and tape-and-reel specifications. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the procurement source provides valid traceability data for automotive-grade components.

Selection Notes

Select this component when dual isolated switching functionality is required in a compact SOT-363 footprint. The integrated 47 kΩ resistors are suitable for standard logic interface levels. Consider the 250 mW power dissipation limit and thermal resistance values when designing for high ambient temperatures or dense PCB layouts.

Part Context

This part belongs to the BCR148 series, which includes variants like BCR148 (SOT-23) and BCR148W (SOT-323). The 'S' designation specifically denotes the dual-transistor SOT-363 package. All variants share similar electrical parameters but differ in physical pinout and thermal characteristics due to their distinct package geometries.

Replacement Considerations

Direct substitutes within the same series include BCR148S (generic package code) or other BCR148 variants if the package form factor can be adapted. Verify pin compatibility and thermal performance before swapping between SOT-23, SOT-323, and SOT-363 packages.
