P1086

Overview

The P1086 is a P-Channel JFET switch designed for low-level analog applications. It operates within a Drain-Gate Voltage of -30 V and a Gate-Source Voltage of 30 V. The device features a Gate-Source Breakdown Voltage of 30 V and a Zero-Gate Voltage Drain Current of 10 mA. Key electrical parameters include a Drain-Source On Resistance of 75 Ω, an Input Capacitance of 45 pF, and a Reverse Transfer Capacitance of 10 pF. Total Device Dissipation is rated at 350 mW with a thermal resistance from junction to case of 125 °C/W.

Feature Summary

Designed specifically for low-level analog switching in sample and hold circuits
Suitable for use in chopper stabilized amplifier configurations
Fabricated using process technology sourced from production line 88

Applications

Sample and hold circuits
Chopper stabilized amplifiers
Low-level analog switching

Procurement Notes

Verify the current lifecycle status before procurement as the component may be obsolete or discontinued by Fairchild Semiconductor. Confirm that the TO-92 package dimensions and pinout match the design requirements. Ensure that the absolute maximum ratings, particularly regarding junction temperature limits, are respected in the final application design to prevent serviceability impairment.

Selection Notes

Select this component when a P-Channel JFET switch is required for analog signal routing. Consider the 75 Ω on-resistance and 45 pF input capacitance for signal integrity analysis. Verify that the -55°C to +150°C operating temperature range meets environmental specifications. Ensure the circuit design accommodates the specific gate-source cutoff voltage characteristics for proper switching control.

Part Context

The P1086 is a discrete semiconductor device manufactured originally by Fairchild Semiconductor Corporation. It belongs to the category of Junction Field Effect Transistors (JFETs) configured as switches. The datasheet indicates it was produced under Fairchild's manufacturing standards, with documentation reflecting revisions from November 2002. It is distinct from linear regulators or other power management ICs sharing similar numerical prefixes.
