BCM856SH6433XTMA1

Overview

The BCM856SH6433XTMA1 is a PNP silicon AF transistor array from Infineon Technologies, packaged in SOT363. It contains two galvanically isolated internal transistors with precision matching (∆IC ≤ 10%). Key electrical parameters include a collector-emitter voltage (VCEO) of 65 V and a maximum collector current (IC) of 100 mA. The device features a transition frequency (fT) of 250 MHz at IC = 20 mA. It operates within a junction temperature range of -65 °C to 150 °C and complies with AEC Q101 standards.

Feature Summary

• Precision matched transistor pair for accurate current mirror applications
• Two internally isolated transistors providing galvanic separation
• Low collector-emitter saturation voltage for efficient switching
• Automotive qualified according to AEC Q101 standards

Applications

• Current mirror circuits requiring high matching accuracy
• Analog signal processing in automotive electronics
• Low-voltage switching applications
• Audio frequency amplification stages

Procurement Notes

Verify the specific suffix XTMA1 against official Infineon documentation to confirm tape-and-reel packaging specifications and orientation requirements. Ensure the component meets RoHS compliance and AEC Q101 qualification status required for your target application environment before finalizing procurement orders.

Selection Notes

Select this component when dual isolated PNP transistors with tight current matching are necessary. The SOT363 package suits space-constrained designs. Consider the 65 V VCEO rating and 100 mA IC limit for circuit design. Verify thermal resistance RthJS of 140 K/W for heat dissipation planning under specified operating conditions.

Part Context

This part belongs to the BCM856S family of PNP transistor arrays. It serves as the complement to the NPN type BCM846S. The series is designed for general-purpose analog and switching applications where matched characteristics and isolation between pairs are critical performance factors.

Replacement Considerations

Check for direct pin-compatible alternatives within the same SOT363 footprint. Verify that substitute parts meet the 65 V VCEO and 100 mA IC ratings. Ensure replacement components offer comparable ∆IC matching and fT performance if used in precision analog circuits.
