BCW70,235

Overview

The BCW70,235 is a PNP general-purpose transistor manufactured by Nexperia USA Inc. It operates within a collector-emitter voltage (VCEO) of -45 V and supports a maximum DC collector current of -100 mA. The device features a transition frequency (fT) of 100 MHz and a total power dissipation of 250 mW at 25 °C ambient temperature. It utilizes the SOT-23 (TO-236AB) surface-mount package with three leads. The component is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• PNP bipolar junction transistor designed for low-current switching and amplification tasks
• Automotive-grade reliability certified to AEC-Q101 qualification standards
• Compact SOT-23 plastic surface-mounted package suitable for space-constrained designs

Applications

• General purpose switching circuits
• Low-frequency amplification stages
• Automotive electronic control modules

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and tape-and-reel specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability. Confirm that the delivered components match the exact part number designation without unauthorized substitutions or alternate marking codes.

Selection Notes

Select this component when a PNP configuration is required for low-voltage, low-current signal processing. The AEC-Q101 qualification makes it suitable for automotive environments where robustness is critical. Compare its 100 mA current rating and 45 V breakdown voltage against circuit requirements to ensure adequate headroom for saturation and cutoff operations in the intended application.

Part Context

This device belongs to the BCW69/BCW70 series of NXP/Nexperia general-purpose transistors. It serves as the PNP counterpart to the BCW69 and complements the BCX70 NPN transistor family. The series is widely utilized in consumer electronics and industrial control systems requiring small-signal handling capabilities in compact surface-mount form factors.

Replacement Considerations

The BCW69 is a direct functional substitute within the same series, distinguished primarily by its DC current gain range. Designers must verify that the alternative's hFE characteristics align with the original circuit biasing requirements before implementation.
