CMJA5050 TR PBFREE

Current Regulation - Diodes, Transistors Overview

The CMJA5050 TR PBFREE is a surface-mount current regulator diode manufactured by Central Semiconductor Corp. It operates within a peak operating voltage of 50 V and supports a maximum regulator current ranging from 55 mA to 88 mA. The device features a maximum limiting voltage of 8.5 V and functions reliably across an extended temperature range from -65°C to +150°C. Packaged in a DFN-123F-2 footprint, this single-configuration component is designed for precise current control applications requiring robust thermal performance and compact form factors.

Current Regulation - Diodes, Transistors Feature Summary

• Provides stable current regulation with adjustable output capabilities between 50 mA and 80 mA.
• Engineered for high-temperature environments with operational limits extending up to 150°C.
• Utilizes a compact surface-mount DFN-123F-2 package suitable for space-constrained designs.

Current Regulation - Diodes, Transistors Applications

• Constant current sources for LED driving circuits
• Biasing networks for transistor amplifiers
• Current limiting protection in sensitive electronic loads

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific current rating variant required, as specifications indicate a range of 55 mA to 88 mA. Confirm the DFN-123F-2 package dimensions match the target PCB layout. Ensure the supplier provides official datasheets confirming RoHS compliance and lead-free status for the TR PBFREE suffix.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed or adjustable constant current source is needed within a 50 V limit. Consider the wide operating temperature range if the application involves harsh thermal conditions. Verify that the required current falls within the documented 55 mA to 88 mA range before finalizing the design.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the CMJA series of current regulator diodes from Central Semiconductor. It is distinct from the CMJD and CMJH series, which typically feature lower current ratings and different voltage profiles. The CMJA series is specifically designed for higher current applications compared to other surface-mount regulators in the manufacturer's portfolio.
