2SK932-24-TB-E

Jfets Overview

The onsemi 2SK932-24-TB-E is an N-channel JFET in a CP (SC-59/SOT-23-3) surface-mount package. It features a drain-to-source voltage of 15 V and a maximum drain current of 50 mA. The device belongs to the '24' rank, with a zero-gate voltage drain current (IDSS) range of 14.5 mA to 24.0 mA at VDS = -5 V. Key electrical parameters include a forward transfer admittance (|yfs|) of 25 mS to 50 mS, an input capacitance (Ciss) of approximately 10 pF, and a noise figure as low as 1.5 dB. It operates up to a junction temperature of 150°C and dissipates 200 mW.

Jfets Feature Summary

• Adopts FBET process technology for enhanced performance
• Provides large forward transfer admittance (|yfs|)
• Features small input capacitance (Ciss)
• Delivers ultralow noise figure suitable for sensitive applications

Jfets Applications

• AM tuner RF amplification
• Low noise amplifier circuits

Jfets Procurement Notes

Verify the specific ordering suffix '-24-' to confirm the IDSS binning range of 14.5 mA to 24.0 mA, as other suffixes like '-23-' indicate different current characteristics. Confirm the package type is CP (SC-59) and that the component is Pb-Free. Ensure the supplier provides the official datasheet PDF (2SK932/D) for final technical validation before integration.

Jfets Selection Notes

Select this part when a low-noise N-channel JFET with high transconductance is required in a compact SOT-23 footprint. The '24' rank offers higher saturation current than the '23' rank. Verify that the 15 V breakdown voltage and 50 mA continuous drain current meet the circuit requirements. Consider the 10 pF input capacitance for high-frequency signal integrity.

Jfets Part Context

This component is part of the 2SK932 family from onsemi, designed specifically for RF front-end applications. It utilizes the proprietary FBET process to achieve superior noise performance compared to standard JFETs. The device is available in tape-and-reel packaging for automated assembly.

Jfets Replacement Considerations

The 2SK932-23-TB-E is a direct pin-compatible alternative within the same family but differs in IDSS ranking (10.0 mA to 17.0 mA). Verify if the lower saturation current of the '-23' variant meets the specific biasing needs of the application.

Jfets FAQ

What is the difference between the 2SK932-23-TB-E and 2SK932-24-TB-E?

The primary difference is the Zero-Gate Voltage Drain Current (IDSS) ranking. The 2SK932-24-TB-E has an IDSS range of 14.5 mA to 24.0 mA, while the 2SK932-23-TB-E has an IDSS range of 10.0 mA to 17.0 mA.

What is the typical noise figure of the 2SK932-24-TB-E?

The typical noise figure is 1.5 dB, measured at VDS = 5 V, Rg = 1 kΩ, ID = 1 mA, and f = 1 kHz.

What package does the 2SK932-24-TB-E use?

It uses the CP package, which is equivalent to SC-59 or SOT-23-3, with a 3-pin configuration.
