Overview
The BCP49H6419XTMA1 is an NPN silicon Darlington bipolar junction transistor manufactured by Infineon Technologies. It is housed in a surface-mount PG-SOT223-4 package and rated for a maximum collector-emitter voltage (VCEO) of 60 V and a continuous DC collector current of 500 mA. The device features a typical current gain (hFE) of 10,000 at 100 mA and 5 V, with a maximum power dissipation of 1.5 W. It operates within a temperature range of -40°C to +150°C and includes an integrated base-emitter resistor.
Feature Summary
- Darlington configuration provides high current gain for efficient switching and amplification
- Integrated base-emitter resistor simplifies circuit design and improves stability
- Robust thermal performance supports operation up to 150°C junction temperature
Applications
- High-side and low-side switching applications
- Relay driver circuits
- Motor control interfaces
- Power amplifier stages
Procurement Notes
Verify the complete ordering code matches the required suffix XTMA1 to ensure correct packaging and tape-and-reel specifications. Confirm that the SOT223-4 footprint aligns with the target PCB layout. Check for any specific handling requirements related to the Darlington structure's saturation characteristics during integration.
Selection Notes
Select this component when high current drive capability is required from a low-power control signal. The integrated resistor eliminates the need for external biasing components, reducing board space. Ensure the load current does not exceed 500 mA and that the thermal management strategy accommodates the 1.5 W dissipation limit under worst-case operating conditions.
Part Context
This part belongs to the BCP49 series of NPN Darlington transistors designed for general-purpose power switching. The series offers a balance of high gain and moderate speed, suitable for applications where driving inductive loads or high-current devices is necessary without complex driver circuits.
Replacement Considerations
Cross-reference with other NPN Darlington transistors in the SOT223-4 package offering similar VCEO and IC ratings. Verify pinout compatibility and thermal resistance values before substitution to ensure equivalent performance in the existing design.
