P1087_D74Z

Overview

The P1087-D74Z is a single P-channel JFET switch manufactured by onsemi, housed in a TO-92 through-hole package. It features a maximum power dissipation of 350 mW and operates within a temperature range of -55°C to +150°C. The device specifies a gate-source breakdown voltage of 30 V and an off-state drain current ranging from 80 µA to 240 µA at Vgs=0. Its on-resistance is rated at 150 Ohms.

Feature Summary

• P-Channel Junction Field Effect Transistor (JFET) configuration for switching applications
• High thermal stability supporting operation up to 150°C
• Through-hole mounting capability via standard TO-92 leaded package

Applications

• Analog signal routing and switching circuits
• Low-noise preamplifier input stages
• Audio signal path control systems

Procurement Notes

Verify the specific suffix D74Z against official datasheets to confirm packaging and tape-and-reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory declarations may vary by production batch and region. Ensure the component matches the required pinout and electrical tolerances for the target design.

Selection Notes

Select this component when a low-leakage P-channel JFET is required for analog switching. The TO-92 package suits prototyping and low-volume designs where surface-mount options are unavailable. Evaluate the 150 Ohm on-resistance against circuit impedance requirements to ensure acceptable signal attenuation during conduction.

Part Context

This part belongs to onsemi's discrete transistor portfolio, specifically within the JFET category. It serves as a passive switching element distinct from MOSFETs or bipolar transistors, offering high input impedance characteristics suitable for precision analog signal handling rather than high-power switching tasks.
