BCP68/ZLF

Overview

The BCP68/ZLF is an NPN bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. It features a collector-emitter voltage rating of 20 V and a maximum continuous collector current of 2 A. The device has a power dissipation capacity of 650 mW and a transition frequency of 170 MHz. It is housed in a surface-mount SOT-223 package with a maximum junction temperature of 150°C. The minimum DC current gain (hFE) is specified as 160 at the manufacturer's test conditions.

Feature Summary

• NPN single transistor configuration for general-purpose switching and amplification
• High current handling capability up to 2 A
• Surface-mount SOT-223 packaging for automated assembly

Applications

• General-purpose switching circuits
• Amplifier stages
• Driver applications requiring moderate current

Procurement Notes

Verify the specific suffix ZLF against official Nexperia documentation to confirm lead-free status and RoHS compliance details. Ensure the ordering part number matches the exact electrical specifications required for the design, as suffixes can indicate variations in tape and reel or environmental certifications. Cross-reference with the latest datasheet revision for any updates on mechanical dimensions or thermal characteristics.

Selection Notes

Select this component when an NPN transistor with 20 V breakdown and 2 A current capacity is needed in a compact SOT-223 footprint. Consider the 170 MHz transition frequency for high-speed switching requirements. Evaluate thermal management needs given the 650 mW power dissipation limit in the specified package. Compare hFE minimums against circuit beta requirements to ensure adequate drive margins.

Part Context

The BCP68 belongs to Nexperia's portfolio of general-purpose NPN transistors designed for robust performance in consumer and industrial electronics. The ZLF suffix typically denotes a lead-free variant compliant with environmental directives. This family offers a balance of current handling and voltage ratings suitable for versatile discrete semiconductor applications.

Replacement Considerations

Consult official Nexperia substitution guides for verified equivalents. Generic replacements must match the 20 V, 2 A, SOT-223 specifications and NPN polarity. Verify pinout compatibility and thermal resistance values before implementation.
