Overview
The CP206-2N4856-CM is a silicon N-channel JFET die designed for analog switching and chopper applications. It features a 21 x 18 mils die size with an 8.0 mils thickness. The device supports a drain-source voltage of 40 V and operates within a junction temperature range of -65 to +175 °C. Electrical characteristics include a maximum gate leakage current of 0.25 nA at 20 V, an on-state resistance of 25 Ω, and input capacitance of 18 pF. The suffix CM indicates the component is supplied as singulated die in a waffle pack tray, having undergone 100% visual inspection per MIL-STD-750.
Feature Summary
- Silicon N-channel small signal JFET structure optimized for analog switching
- High operating and storage junction temperature capability up to 175 °C
- Low input capacitance and fast switching times suitable for precision circuits
- Die form factor allows for custom packaging and integration
Applications
- Analog switching circuits
- Chopper amplifier applications
- Precision low-level signal processing
Procurement Notes
Verify the specific wafer process status before ordering, as the CP206 process has been discontinued and transitioned to End of Life. Confirm if the replacement CP216 process meets all design requirements. Ensure the CM suffix is correctly specified to receive singulated die in a waffle pack tray with 100% visual inspection according to MIL-STD-750 standards.
Selection Notes
Select this bare die when custom packaging or specific substrate integration is required rather than standard discrete packages. Consider the CP216-2N4856-CM as the direct replacement due to the discontinuation of the CP206 wafer process. Evaluate thermal management capabilities given the high maximum junction temperature rating of 175 °C for the application environment.
Part Context
This component belongs to the Central Semiconductor 2N4856 series of N-channel JFETs. It corresponds to the standard 2N4856 transistor specification but is provided as a bare die (CP206 process) instead of a packaged device. The CM suffix specifically denotes the packaging format as singulated die in a waffle pack tray.
Replacement Considerations
The CP206 wafer process is discontinued. The official replacement part numbers are CP216-2N4856-CM, CP216-2N4856-CT, and CP216-2N4856-WN. Verify electrical parameter continuity between the CP206 and CP216 processes during qualification.
