SMP4117ATR

Overview

The SMP4117ATR is an N-Channel JFET in a surface-mount SOT23 package, supplied on a 7-inch tape and reel. It features a gate-to-source breakdown voltage of -40V and a typical gate leakage current of 120fA at 20V. The device exhibits an input capacitance of 1.8pF and a forward transconductance ranging from 70 to 210μS. Maximum ratings include a continuous power dissipation of 350mW and an operating junction temperature range of -55°C to 150°C.

Feature Summary

Ultra-low gate leakage current for high-impedance signal integrity
High radiation tolerance via proprietary InterFET geometry
Low input capacitance to minimize circuit loading
RoHS, REACH, and CMR compliant construction

Applications

General purpose buffers and signal mixers
Military radar and satellite communications systems
Medical imaging and ultrasound monitoring equipment

Procurement Notes

Verify the specific suffix 'ATR' confirms the 7-inch tape and reel packaging format with a maximum quantity of 3,000 pieces per reel. Ensure the ordering part number matches the required electrical binning options, as custom test parameters are available directly from the manufacturer. Confirm compliance requirements align with project specifications before finalizing procurement.

Selection Notes

Select this component when ultra-high input impedance and low leakage are critical design constraints. The SOT23 package facilitates automated surface-mount assembly processes. Consider the A-variant specifications for tighter cutoff voltage limits if precise biasing is required. Evaluate thermal derating curves to ensure adequate heat dissipation within the specified operating temperature range.

Part Context

This device belongs to the 2N4117/A series of N-Channel JFETs designed for mid-to-high frequency applications. It serves as a direct industry standard cross-reference for parts such as SST4117 and MMBF4117. The product line includes through-hole and bare die variants alongside the surface-mount option.
