BC857BHZGT116

Overview

The BC857BHZGT116 is a PNP general-purpose amplification transistor designed for automotive applications. It complies with the AEC-Q101 standard, ensuring high reliability in vehicle environments. The device utilizes an SST3 (SOT-23) surface-mount package with three terminals. Key electrical specifications include a collector-emitter voltage of -45V and a continuous collector current of -0.1A. The DC current gain (hFE) is graded within the range of 210 to 480. Power dissipation is rated at 0.2W, with an operating storage temperature range from -65°C to 150°C.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q101 standards
• Complementary pairing with the BC847BHZG NPN transistor
• High-voltage capability suitable for signal amplification

Applications

• General signal amplification in automotive electronic systems
• Low-frequency amplification circuits requiring high reliability
• Complementary amplifier stages paired with NPN counterparts

Procurement Notes

Verify that the ordering suffix matches the specific tape-and-reel configuration required for automated assembly processes. Confirm that the component grade corresponds to the automotive AEC-Q101 specification rather than standard industrial grades. Ensure the hFE binning aligns with circuit design requirements for consistent gain performance across production batches.

Selection Notes

Select this component when designing for automotive environments where AEC-Q101 compliance is mandatory. It serves as the PNP counterpart to the BC847BHZG, facilitating complementary circuit designs. Consider the SOT-23 package constraints for thermal management and board space. Verify that the -45V voltage rating meets the maximum operational limits of the target application circuit.

Part Context

This part belongs to Rohm Semiconductor's BC857 series of small-signal transistors. The 'HZ' suffix indicates automotive-grade qualification under AEC-Q101, distinguishing it from standard commercial variants like the BC857BT. The 'T116' suffix typically denotes the specific packaging format, such as tape and reel quantity, intended for surface-mount technology manufacturing lines.

Replacement Considerations

Publicly confirmed substitutes include the BC847BHZG for complementary NPN functionality. Other compatible parts within the same automotive family may be considered if pinout and electrical characteristics match exactly.
