Description and Introduction

Current regulator diode Here are the factual details about part J502 manufacturer SI specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Part Number:** J502  
### **Manufacturer:** SI (Siliconix or Vishay Siliconix)  

#### **Specifications:**  
- **Type:** JFET (Junction Field-Effect Transistor)  
- **Polarity:** N-Channel  
- **Maximum Drain-Source Voltage (Vds):** 40V  
- **Maximum Gate-Source Voltage (Vgs):** 40V  
- **Drain Current (Id):** 10mA (typical)  
- **Power Dissipation (Pd):** 350mW  
- **Input Capacitance (Ciss):** 5pF (typical)  
- **Output Capacitance (Coss):** 3pF (typical)  
- **Reverse Transfer Capacitance (Crss):** 1.5pF (typical)  
- **Gate-Source Cutoff Voltage (Vgs(off)):** -0.5V to -4.0V  

#### **Description:**  
The J502 is a low-noise, high-input-impedance N-channel JFET designed for small-signal amplification applications. It is commonly used in audio preamplifiers, impedance converters, and sensor interfaces due to its low leakage current and stable performance.  

#### **Features:**  
- **Low Noise:** Optimized for high-fidelity audio and sensitive signal processing.  
- **High Input Impedance:** Suitable for buffering and impedance matching.  
- **Low Leakage Current:** Ensures minimal signal distortion.  
- **Compact Package:** Typically available in TO-92 or similar through-hole packages.  

These details are based on manufacturer datasheets and technical documentation. For exact performance characteristics, refer to the official SI (Siliconix/Vishay) datasheet.
