MMBTA64LT1

Single Bipolar Transistors Overview

The MMBTA64LT1G is a PNP Darlington transistor manufactured by onsemi, housed in an SOT-23-3 surface-mount package. It features a maximum collector-emitter voltage (VCEO) of 30 V and a maximum DC collector current of 500 mA. The device has a minimum DC current gain (hFE) of 10,000 and a power dissipation rating of 225 mW. Operating temperatures range from -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• High current gain capability for sensitive signal amplification
• Compact SMD packaging for space-constrained designs
• Wide operating temperature range for industrial environments

Single Bipolar Transistors Applications

• General-purpose switching applications
• Signal amplification circuits
• Driver stages for relays or LEDs

Single Bipolar Transistors Procurement Notes

Verify the exact suffix against official documentation, as 'MMBTA64LT1' may refer to the standard tape-and-reel variant often designated as MMBTA64LT1G. Confirm RoHS compliance status and specific shipping configuration requirements with the manufacturer or authorized distributor before ordering.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain PNP switch is required in a small footprint. Ensure the circuit design accounts for the 225 mW power dissipation limit and the 30 V voltage rating. Compare against the legacy MMBTA64 if higher current capacity is needed, noting the difference in package and current specifications.

Single Bipolar Transistors Part Context

This part belongs to the MMBTA64L series of PNP Darlington transistors. It serves as a modern, lead-free replacement for older through-hole or non-RoHS compliant variants like the MMBTA64, which is listed as obsolete. The LT1G suffix typically indicates the specific reel packaging and RoHS compliance.

Single Bipolar Transistors Replacement Considerations

The MMBTA64 is an obsolete direct electrical equivalent but differs in current rating (1.2 A vs 500 mA). Verify pinout compatibility and thermal management requirements when substituting.
