CMJA5050 TR13 PBFREE

Overview

The CMJA5050 TR13 PBFREE is a single-channel current regulator diode manufactured by Central Semiconductor. It operates within a maximum peak working voltage of 50 V and provides an adjustable regulation current ranging from 50 mA to 80 mA. The device features a maximum limit voltage of 8.5 V and supports a power dissipation of 1.0 W. It is housed in a surface-mount DFN-123F-2 package with SMD/SMT termination. The component is rated for operation across an extended temperature range from -65°C to +150°C.

Feature Summary

• Provides stable current regulation with adjustable output characteristics
• Designed for compact surface-mount integration via DFN-123F-2 packaging
• Capable of reliable operation under extreme thermal conditions

Applications

• Constant current sources for LED driving circuits
• Biasing networks for semiconductor sensors
• Current limiting protection in low-power electronic systems

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation, as variations such as BK may indicate distinct binning or testing criteria within the same family. Confirm RoHS compliance status through the latest datasheet before finalizing procurement specifications. Ensure that the ordering quantity aligns with the standard factory pack size of 3500 units to avoid handling discrepancies during assembly.

Selection Notes

Select this component when a fixed current source is required within a 50 V operational envelope. The wide operating temperature range makes it suitable for harsh environments where standard silicon devices might fail. Consider the DFN-123F-2 footprint constraints during PCB layout to ensure adequate thermal dissipation for the 1.0 W power rating.

Part Context

This device belongs to the CMJA5050 series of current regulator diodes produced by Central Semiconductor. The series is engineered to provide precise current control without the complexity of active feedback loops. It serves as a passive alternative to more complex constant current drivers in cost-sensitive applications requiring high reliability.
