2N5638 Description

Short technical summary and product information.

The 2N5638 is an N-channel JFET (Junction Field-Effect Transistor) manufactured by On Semiconductor. It is designed for low-level analog switching, sample and hold circuits, and chopper stabilized amplifiers. Key electrical specifications include a drain-source voltage (Vdss) of 30V, zero-gate voltage drain current (IDSS) of 50 mA typical, and a maximum drain-source on-resistance (rDS(on)) of 30 Ω at VGS=0V and ID=1.0mA. The device features low input capacitance (Ciss) of 10pF and reverse transfer capacitance (Crss) of 4.0pF, contributing to fast switching speeds with typical turn-on delay of 4ns, rise time 5ns, turn-off delay 5ns, and fall time 10ns. The JFET is housed in a through-hole TO-92-3 package (TO-226-3), suitable for easy PCB mounting. Maximum power dissipation is 350mW at 25°C case temperature, with junction-to-case thermal resistance of 125°C/W and junction-to-ambient of 357°C/W. The operating temperature range is -55°C to 150°C. This device is indicated as RoHS3 compliant and REACH unaffected, though compliance data is unverified.
