Overview
The CP206-2N4393-WN is a silicon N-channel small signal Junction Field-Effect Transistor (JFET) bare die intended for analog switching and chopper applications. It features a 21 x 18 mils die size with an 8.0 mils thickness. The device operates within a junction temperature range of -65 to +175 °C. Key electrical parameters include a maximum gate-drain voltage of 40 V, a drain-source saturation current (IDSS) ranging from 5.0 to 30 mA, and a gate-source cutoff voltage (VGS(OFF)) between 0.5 and 3.0 V. The on-resistance (rDS(ON)) is specified at 100 Ω under standard test conditions.
Feature Summary
- Designed specifically for high-performance analog switching and chopper circuits
- Features low capacitance characteristics to support fast switching speeds
- Provides high off-isolation with negligible leakage current in the off state
- Utilizes a hermetically sealed wafer process suitable for demanding environments
Applications
- Analog switches
- Chopper circuits
- Sample-and-hold circuits
- Normally 'on' switches
- Current limiters
Procurement Notes
Verify the specific suffix designation when ordering, as it determines the physical packaging format. The '-WN' suffix indicates a full unsawn wafer configuration where reject dies are inked. Confirm availability status, as the CP206 wafer process has been discontinued and transitioned to End of Life status by the manufacturer.
Selection Notes
Select this component based on its specific die dimensions and pad layout requirements for custom packaging solutions. Ensure the application circuit can accommodate the specified IDSS range of 5.0 to 30 mA and the VGS(OFF) limits. Verify that the operating environment remains within the -65 to +175 °C junction temperature rating.
Part Context
This part belongs to the Central Semiconductor CP206 series of bare die JFETs. It corresponds to the standard 2N4393 transistor specification but is supplied as a raw semiconductor die rather than a packaged component. The product line targets designers requiring custom hybrid integration or specialized packaging configurations.
Replacement Considerations
The CP206 wafer process is officially discontinued. The documented replacement is the CP216-2N4393-WN. Designers should evaluate the CP216 series for compatibility, noting potential differences in wafer processing or electrical binning compared to the legacy CP206 version.
FAQ
What does the '-WN' suffix indicate for this part?
The '-WN' suffix denotes that the device is supplied as a full unsawn wafer. All dies are 100% tested, and any rejected dies are marked with ink.
What is the typical switching speed of this JFET die?
The datasheet specifies a turn-on time (ton) of 15 ns and a turn-off time (toff) of 50 ns under standard test conditions.
Is this component available in a surface-mount package?
No, this specific part number is a bare die. While other variants in the 2N4393 family exist in packages like SOT-23, the CP206-2N4393-WN must be manually mounted or integrated into a custom substrate.
