CMXT3906 TR TIN/LEAD

Overview

The CMXT3906 TR TIN/LEAD is a dual PNP bipolar junction transistor array manufactured by Central Semiconductor Corp. It utilizes silicon technology and is housed in an SOT-26 (SOT-23-6) surface-mount package. The device supports a maximum collector-emitter voltage of 40V and a continuous collector current of 200mA per element. Key electrical parameters include a transition frequency of 250MHz, a power dissipation rating of 350mW, and a DC current gain minimum of 100 at 10mA and 1V. The component operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual PNP configuration integrating two independent transistors in a single compact package for space-constrained designs.
• High-speed switching capability with a 250MHz transition frequency suitable for RF and high-frequency applications.
• Robust thermal performance allowing operation up to a junction temperature of +150°C.

Applications

• General-purpose signal amplification circuits requiring dual complementary or matched PNP elements.
• High-frequency switching applications utilizing the specified transition frequency characteristics.
• Compact consumer electronics where board space is limited due to the small SOT-26 footprint.

Procurement Notes

Verify the specific ordering suffix 'TIN/LEAD' against the manufacturer's current datasheet to confirm lead content status. Standard RoHS-compliant versions typically use tin plating. Ensure the procurement specification matches the required environmental compliance for the target assembly process.

Selection Notes

Select this component when a dual PNP configuration is required in a small outline package. Compare the 200mA current limit and 40V voltage rating against circuit requirements. Consider the SOT-26 thermal resistance if multiple elements are driven simultaneously to ensure power dissipation limits are not exceeded.

Part Context

This part belongs to the CMXT3906 family of dual PNP transistors from Central Semiconductor. It shares core electrical specifications with the standard CMXT3906 but differs in packaging material or plating composition indicated by the suffix. It serves as a compact alternative to discrete single-transistor solutions.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the CMXT3906 TR PBFREE. Verify pinout compatibility and electrical tolerances before substitution. Other generic MMBT3906-based dual arrays may require schematic review due to potential differences in saturation voltage or gain ranges.
