BC847CMB,315

Overview

The BC847CMB,315 is an NPN general-purpose bipolar junction transistor manufactured by Nexperia. It features a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. The device utilizes a DFN1006B-3 (SOT883B) leadless surface-mount package with dimensions of 1.0 x 0.6 mm. Electrical characteristics include a minimum DC current gain (hFE) of 420 at 2 mA and 5 V, a transition frequency of 100 MHz, and a power dissipation capability of 250 mW.

Feature Summary

• High DC current gain selection for sensitive signal amplification
• Ultra-small leadless DFN package for dense board layouts
• Low saturation voltage for efficient switching operations

Applications

• General-purpose switching circuits
• Small-signal amplification stages
• Digital logic interface buffering

Procurement Notes

Verify the specific suffix '315' corresponds to the DFN1006B-3 package variant during procurement. Confirm RoHS compliance status and check for automotive qualification requirements if applicable to the target application environment. Ensure ESD handling protocols are followed due to the small form factor.

Selection Notes

Select this component when space constraints require a leadless footprint smaller than standard SOT-23 packages. Choose the C gain group for applications demanding high beta values in amplifier designs. Verify thermal management capabilities as the small package limits heat dissipation compared to larger through-hole alternatives.

Part Context

This part belongs to the BC847 series of NPN general-purpose transistors. It serves as a compact alternative to traditional plastic packages like SOT-23, offering similar electrical performance in a significantly reduced footprint. The series is widely used in portable electronics and consumer devices where board real estate is limited.

Replacement Considerations

Direct pin-compatible replacements include other manufacturers' BC847C variants in DFN1006B-3 packages. Verify that substitute parts meet the same hFE range and voltage ratings. Cross-reference datasheets for thermal resistance differences between leadless and plastic packages.
