CPH5901G-TL-E

Overview

The CPH5901G-TL-E is a composite semiconductor device manufactured by onsemi, integrating an N-Channel JFET and an NPN Bipolar Junction Transistor (BJT) within a single package. Designed for high-frequency applications, the component operates with a maximum collector-emitter voltage of 50V and supports collector currents up to 150mA for the BJT section, while the JFET section handles gate-source voltages up to 15V and drain currents between 6mA and 20mA. The device is housed in a surface-mount SC-88 (SOT-363) package, featuring five terminals and lead-free construction compliant with environmental standards. It is rated for operation at temperatures up to 150°C and is classified under ECCN code EAR99.

Feature Summary

• Integrates an N-Channel JFET and an NPN BJT into a single composite structure for space-constrained designs
• Optimized for high-frequency amplification tasks including AM radio stages
• Supports low-frequency audio amplification applications
• Utilizes a compact surface-mount package suitable for automated assembly

Applications

• High-frequency amplifier circuits
• AM radio signal amplification stages
• Low-frequency audio amplifier stages

Procurement Notes

Verify the manufacturer designation carefully, as this component was originally developed by Sanyo Semicon Device and is now distributed by onsemi. Confirm that the specific suffix TL-E corresponds to the required packaging format and terminal finish specifications. Ensure compliance with RoHS directives and check for any specific handling requirements related to the composite nature of the internal JFET and BJT structures during integration.

Selection Notes

Select this component when a design requires both JFET input characteristics and BJT output drive capabilities within a minimal footprint. It is suitable for applications needing high-frequency performance combined with low-frequency amplification functions. Consider the 50V voltage rating and current limits to ensure they align with the circuit's operational boundaries. Evaluate the thermal management requirements given the 150°C maximum operating temperature limit.

Part Context

This part belongs to the CPH series of composite transistors, which combine different transistor types to provide specialized amplification functions. Originally produced by Sanyo, these devices are widely used in consumer electronics for RF and audio processing. The transition to onsemi distribution maintains the original technical specifications and pinout configurations, ensuring continuity for existing designs.

Replacement Considerations

Direct substitutes include the CPH5901 and CPH5902 from Sanyo Semicon Device, which share similar functional descriptions. Other potential replacements may include components from Toshiba Semiconductor such as the 2SK711 series, though verification of pin compatibility and electrical parameters is required.
