BSR58 Description

Short technical summary and product information.

The BSR58 is an N-Channel JFET manufactured by On Semiconductor (onsemi). It is designed for low-power chopper or switching applications, sourced from process 51. The device is a low-frequency low-noise amplifier JFET.

 

Key electrical specifications include a maximum drain-gate voltage of 40 V, maximum gate-source voltage of -40 V, forward gate current of 50 mA, and total power dissipation of 250 mW. The zero-gate voltage drain current (IDSS) ranges from 8.0 to 80.0 mA at VDS=15V. Gate-source cutoff voltage is between 0.8 and 4.0 V, and drain-source on resistance is 60 Ω maximum. The device offers fast switching with delay and rise times of 10 ns and turn-off time of 100 ns.

 

The BSR58 is offered in a surface-mount SOT-23-3 package (also known as TO-236-3, SC-59). It is available in tape and reel packaging with a standard quantity of 3000 pieces. The operating junction temperature range is -55°C to +150°C, and the storage temperature range is the same.
