ABC858C-HF

Single Bipolar Transistors Overview

The ABC858C-HF is a silicon PNP bipolar junction transistor (BJT) manufactured by Comchip Technology, designed for automotive applications. It features a single configuration housed in an SOT-23-3 surface-mount package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 30 V and a collector-base voltage (VCBO) of 30 V. The device supports a continuous collector current of 100 mA with a gain-bandwidth product (fT) of 100 MHz. DC current gain (hFE) ranges from a minimum of 125 to a maximum of 800. The emitter-base voltage (VEBO) is rated at 5 V, and the collector-emitter saturation voltage is 650 mV. Operating temperatures span from -55°C to +150°C.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official documentation. Ensure storage conditions maintain integrity prior to assembly. Check specific automotive qualification standards required for your application. Validate package marking against datasheet specifications upon receipt.

Single Bipolar Transistors Selection Notes

Select this component when automotive reliability is required alongside standard PNP switching capabilities. The SOT-23-3 package suits space-constrained designs. Consider the hFE range of 125 to 800 for circuit gain requirements. Verify thermal management needs given the 150°C maximum junction temperature limit. Compare against non-automotive equivalents if cost is a primary driver but automotive grade is not mandatory.

Single Bipolar Transistors Part Context

This part belongs to Comchip Technology's lineup of silicon bipolar transistors. It shares the BC858 series naming convention but carries the 'A' prefix indicating automotive grade. It differs from the standard BC858C-HF by meeting stricter automotive quality standards while maintaining similar electrical characteristics. The 'HF' suffix denotes halogen-free construction.

Single Bipolar Transistors Replacement Considerations

BC858C-HF is a functional equivalent with identical electrical ratings but lacks automotive qualification. BC858BW-HF offers higher minimum gain but is also automotive-grade. Verify pinout compatibility and thermal performance before substitution.
