BC68-25PASX

Overview

The BC68-25PASX is an NPN medium power transistor from the BC68PAS series, manufactured by Nexperia. It operates with a collector-emitter voltage of 20 V and supports a continuous collector current of 2 A, with a peak pulse current capability of 3 A. The device features two current gain selections; the BC68-25PAS variant specifies a minimum DC current gain (hFE) of 160 at IC = 500 mA and VCE = 1 V. It is housed in an ultra-thin DFN2020D-3 (SOT1061D) leadless SMD plastic package measuring 2 x 2 x 0.65 mm, designed for reduced PCB area requirements and excellent thermal conductivity via an exposed heatsink.

Feature Summary

• High collector current capability supporting up to 2 A continuous operation
• Two distinct current gain selections available within the series
• Leadless very small SMD plastic package with medium power capability
• Exposed heatsink structure providing excellent thermal and electrical conductivity

Applications

• Linear voltage regulators
• Low-side switches
• Battery-driven devices
• Power management circuits
• MOSFET drivers
• Amplifiers

Procurement Notes

Verify that the specific ordering suffix matches the required current gain bin, as the BC68PAS series offers multiple hFE options. Confirm the component status is production-grade rather than preliminary or objective data. Ensure the procurement channel sources from authorized Nexperia distributors to guarantee authenticity. Check the most recent datasheet revision for any updates to limiting values or thermal characteristics before finalizing design-in specifications.

Selection Notes

Select the BC68-25PAS variant when a guaranteed minimum DC current gain of 160 is required at 500 mA collector current. Consider the DFN2020D-3 package dimensions if strict board space constraints exist. Evaluate the thermal resistance parameters against the intended PCB copper area and layer count to ensure junction temperature limits are not exceeded during operation. Verify compatibility with automatic optical inspection processes due to the visible side pads.

Part Context

The BC68PAS series consists of NPN medium power transistors designed for surface-mount applications. The PNP complement is the BC69PAS series. These components utilize an ultra-thin DFN2020D-3 leadless package with side-wettable flanks to enhance solder joint reliability and thermal performance. The series is suitable for general-purpose switching and amplification tasks where compact form factors and high current handling are prioritized.

Replacement Considerations

The BC69PAS series serves as the direct PNP complement. For pin-compatible replacements, verify that alternative transistors match the 20 V collector-emitter voltage rating and 2 A continuous current capacity. Ensure substitute packages maintain similar thermal dissipation characteristics given the exposed pad design.
