KSK596ABU

Overview

The KSK596ABU is a silicon N-channel Junction Field-Effect Transistor (JFET) manufactured by onsemi. It utilizes the FBET process to achieve low output noise voltage and excellent transient characteristics. The device is housed in a TO-92S1 through-hole package. Key electrical ratings include a maximum gate-drain voltage of -20 V, a continuous drain current of 1 mA, and a power dissipation of 100 mW at 25°C ambient temperature. The junction temperature rating reaches 150°C.

Feature Summary

• Designed specifically for capacitor microphone applications in audio equipment and telephones
• Features excellent voltage characteristic performance
• Provides excellent transient characteristic response

Applications

• Audio equipment circuits
