2N5485_D27Z

Overview

The onsemi 2N5485_D27Z is an N-channel Junction Field-Effect Transistor (JFET) designed for RF and analog switching applications. It utilizes silicon technology and is housed in a TO-92-3 through-hole package. Key electrical parameters include a gate-source breakdown voltage of -25 V, a continuous drain current of 10 mA, and a power dissipation rating of 350 mW. The device operates within a temperature range of -55°C to +150°C and features a forward transconductance ranging from 0.0035 S to 0.007 S.

Feature Summary

• Single N-channel configuration optimized for low on-resistance analog switching
• Silicon-based construction supporting high junction temperatures up to 150°C
• Interchangeable source and drain terminals in compatible packages

Applications

• Low on-resistance analog switches
• Electronic switching circuits
• RF amplifier stages

Procurement Notes

Verify the specific suffix _D27Z against official manufacturer documentation to confirm packaging and handling specifications. Confirm availability status as related variants may be obsolete or restricted. Ensure compliance with RoHS directives by checking the detailed certification data provided in the component datasheet before procurement.

Selection Notes

Select this component when an N-channel JFET with a -25 V gate-source breakdown voltage and 10 mA continuous drain current is required. Consider the TO-92-3 package for through-hole mounting constraints. Verify that the specified transconductance range meets the circuit's gain requirements and that the operating temperature range aligns with the environmental conditions.

Part Context
