Description and Introduction

N-channel junction FET The BF862 is an N-channel JFET (Junction Field-Effect Transistor) manufactured by **PHILIPS** (now NXP Semiconductors). Here are its key specifications:

- **Type**: N-channel JFET  
- **Maximum Drain-Source Voltage (VDS)**: 25V  
- **Maximum Gate-Source Voltage (VGS)**: ±20V  
- **Maximum Continuous Drain Current (ID)**: 30mA  
- **Power Dissipation (Ptot)**: 300mW  
- **Gate-Source Cutoff Voltage (VGS(off))**: -0.3V to -1.5V  
- **Zero-Gate-Voltage Drain Current (IDSS)**: 5mA to 15mA  
- **Input Capacitance (Ciss)**: 8pF (typical)  
- **Output Capacitance (Coss)**: 3pF (typical)  
- **Reverse Transfer Capacitance (Crss)**: 1.5pF (typical)  
- **Noise Figure (NF)**: Low noise, suitable for RF applications  
- **Package**: SOT23 (3-pin)  

The BF862 is commonly used in **high-frequency, low-noise amplifier circuits**, such as RF and audio applications.  

(Note: PHILIPS' semiconductor division became NXP Semiconductors, so newer datasheets may reference NXP.)
