CPH6904-TL-E

Overview

The CPH6904-TL-E is a dual N-channel JFET in a CPH6 surface-mount package. It integrates two chips equivalent to the CPH3910 into one component, improving mounting efficiency. Key electrical parameters include a Drain-to-Source Voltage (VDSX) of 25 V and a Drain Current (ID) of 50 mA. The device operates with a Drain Current (IDSS) range of 20 to 40 mA at VDS = 5 V. Forward Transfer Admittance (|yfs|) ranges from 30 to 40 mS. Input Capacitance (Ciss) is 6.0 pF and Reverse Transfer Capacitance (Crss) is 2.3 pF at 1 MHz. Noise Figure (NF) is between 2.1 and 2.8 dB at 100 MHz. Allowable Power Dissipation (PD) is 400 mW per unit, with a total dissipation (PT) of 700 mW.

Feature Summary

• Dual configuration integrating two J-FETs within a single CPH6 package for improved mounting efficiency
• Equivalent performance to two individual CPH3910 devices consolidated into one component

Applications

• Low noise amplifier circuits
• Impedance conversion stages
• Analog switch applications

Procurement Notes

Verify the specific ordering suffix TL-E confirms tape and reel packaging with a minimum quantity of 3,000 pieces per reel. Confirm the component is Pb-Free compliant as indicated by the datasheet designation. Ensure the procurement documentation references the correct JEITA/JEDEC package standards SC-74, SOT-26, or SOT-457 for mechanical compatibility.

Selection Notes

Select this component when a dual N-channel JFET solution is required in a compact surface-mount footprint. The CPH6904 serves as a direct replacement for using two separate CPH3910 units, reducing board space. Verify that the 25 V breakdown voltage and 400 mW power dissipation limits align with the circuit's maximum operating conditions.

Part Context

This device belongs to onsemi's JFET product line designed for analog signal processing. It utilizes the CPH6 package, which corresponds to JEITA and JEDEC standards SC-74, SOT-26, and SOT-457. The component is manufactured as a Pb-Free device intended for general-purpose electronic applications requiring dual JFET functionality.

Replacement Considerations

The datasheet explicitly states the CPH6904 is formed with two chips being equivalent to the CPH3910 placed in one package. Designers replacing discrete CPH3910 components should account for the combined thermal characteristics and the specific pinout differences inherent to the CPH6 package.
