2SK3796-3-TL-E

Overview

The 2SK3796-3-TL-E is an N-channel JFET from onsemi, packaged in the SMCP (SOT-416) form factor. It operates with a Drain-to-Source Voltage of 30V and a Gate-to-Drain Voltage of -30V. The device supports a continuous Drain Current of 10mA and dissipates up to 100mW. For the '-3' ranking suffix, the Drain Current at zero gate bias (IDSS) ranges from 1.2mA to 3.0mA. The typical Forward Transfer Admittance (|yfs|) is 6.5mS at VDS=10V. Input Capacitance (Ciss) is typically 4pF, while Reverse Transfer Capacitance (Crss) is 1.1pF at 1MHz.

Feature Summary

• Low input capacitance for high-frequency signal integrity
• Minimal gate leakage current for stable biasing
• Lead-free construction compliant with environmental standards

Applications

• Low-frequency general-purpose amplifiers
• Impedance conversion circuits
• Analog switches

Procurement Notes

Verify the ordering suffix matches the required IDSS binning category. Confirm the package type aligns with the PCB land pattern design. Ensure the component meets lead-free specifications if mandated by project requirements. Validate that the supply chain source provides authentic documentation matching the manufacturer's datasheet.

Selection Notes

Select this component based on the specific IDSS range required for the circuit design. The '-3' suffix indicates a drain current between 1.2mA and 3.0mA. Verify that the 30V breakdown voltage suits the operating conditions. Consider the small signal characteristics and low capacitance for high-impedance applications.

Part Context

This part belongs to the 2SK3796 family, differentiated by IDSS rankings. Variants include the -2-TL-E (0.6-1.5mA) and -4-TL-E (2.5-6.0mA). All share identical electrical limits and package dimensions. The SMCP package offers a compact footprint suitable for space-constrained designs.

Replacement Considerations

Direct substitutes within the same family are the 2SK3796-2-TL-E and 2SK3796-4-TL-E, provided their IDSS ranges fit the design constraints. Cross-vendor replacements require verification of pinout compatibility and matching electrical parameters such as V(BR)GDS and |yfs|.
