FMMT411TA

Single Bipolar Transistors Overview

The FMMT411TA is an NPN silicon planar bipolar transistor designed for low-voltage avalanche mode operation. It features a collector-base voltage of 80 V, a collector-emitter voltage of 15 V, and a continuous collector current of 900 mA. The device dissipates up to 800 mW of power and operates within a temperature range of -55 °C to +150 °C. Packaged in a surface-mount SOT23 (Type DN) housing, it delivers a typical avalanche current of 35 A with fast edge generation capabilities.

Single Bipolar Transistors Feature Summary

• Specifically engineered for reliable low-voltage avalanche mode operation
• Produces high-current pulses with fast edges due to tight process control and low inductance packaging
• Qualified to JEDEC standards for high reliability applications

Single Bipolar Transistors Applications

• Laser diode drivers for ranging and measurement (LIDAR)
• Fast edge switch generators
• High-speed pulse generators

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TA' corresponds to the required reel packing quantity of 3000 units. Confirm that the component meets all applicable RoHS and halogen-free environmental requirements for your manufacturing process. Ensure design compliance with the manufacturer's standard terms and conditions regarding product selection and application suitability.

Single Bipolar Transistors Selection Notes

Select this component when low-voltage avalanche characteristics are required for generating fast electrical pulses. Evaluate circuit layout parasitics carefully, as excessive inductance reduces current pulse height and slew rates. Verify thermal performance through measurement, as PCB thermal resistance depends on design factors and proximity to other components.
