MBT6429DW1T1G

Overview

The MBT6429DW1T1G is a dual NPN bipolar junction transistor manufactured by onsemi. It utilizes silicon technology and is housed in an SC-70-6 surface-mount package. The device supports a maximum DC collector current of 200 mA and operates with a collector-emitter voltage (VCEO) of 45 V and a collector-base voltage (VCBO) of 55 V. The emitter-base voltage (VEBO) is rated at 6 V. Key electrical characteristics include a collector-emitter saturation voltage of 600 mV, a power dissipation capability of 150 mW, and a gain-bandwidth product (fT) of 700 MHz. The minimum DC current gain (hFE) is specified as 500. The component functions within a temperature range from -55°C to +150°C.

Feature Summary

• Dual NPN configuration integrating two transistors in a single compact package for space-constrained designs.
• High DC current gain ensures efficient signal amplification with low base drive requirements.
• Wide operating temperature range supports functionality in extreme thermal environments.

Applications

• General-purpose signal amplification circuits
• Switching applications requiring moderate current handling
• Low-power analog interface stages

Procurement Notes

Verify the specific ordering suffix and manufacturer lot codes against official onsemi documentation to ensure authenticity. Confirm that the SC-70-6 package dimensions match the target PCB footprint. Check RoHS compliance status through the manufacturer's environmental declarations. Validate that the component meets the required automotive or industrial qualification standards if applicable to the end-use environment.

Selection Notes

Select this component when a dual NPN topology is required in a small form factor. Compare the 150 mW power dissipation limit against the expected thermal load in the application. Ensure the 45 V collector-emitter voltage rating exceeds the maximum circuit voltage. Consider the 700 MHz transition frequency for high-speed switching or amplification needs relative to the signal bandwidth.

Part Context

This part belongs to the MBT6429DW1 series of dual NPN transistors. It shares similar electrical characteristics with other devices in the family but differs in packaging and specific pinout configurations. The SC-70-6 package distinguishes it from single-transistor counterparts like the MMBT6429LT1G, which uses an SOT-23-3 package. This series is designed for applications requiring multiple matching transistors in a minimal board area.

Replacement Considerations

Direct substitutes may include NSVMMBT6429LT1G, though it features a single transistor in an SOT-23-3 package rather than a dual configuration in SC-70-6. Verify pin compatibility and thermal performance before substitution. Other dual NPN devices in SC-70-6 packages should be evaluated for matching VCEO, IC, and hFE specifications.
