Description and Introduction

PNP Epitaxial Silicon Transistor The part **KSA928AYBU** is manufactured by **FAIRCHILD**. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Transistor Type:** PNP Bipolar Junction Transistor (BJT)  
- **Collector-Emitter Voltage (VCE):** -120V  
- **Collector-Base Voltage (VCB):** -120V  
- **Emitter-Base Voltage (VEB):** -5V  
- **Collector Current (IC):** -50mA  
- **Power Dissipation (PD):** 200mW  
- **DC Current Gain (hFE):** 60 to 240 (at IC = -2mA, VCE = -5V)  
- **Transition Frequency (fT):** 50MHz  
- **Operating Junction Temperature (TJ):** -55°C to +150°C  
- **Package Type:** SOT-23 (SC-59)  

### **Descriptions:**  
- The **KSA928AYBU** is a high-voltage PNP transistor designed for general-purpose amplification and switching applications.  
- It is suitable for low-power circuits requiring a small footprint due to its SOT-23 package.  

### **Features:**  
- **High Voltage Capability** (up to -120V VCE)  
- **Low Noise** for signal amplification  
- **Compact SOT-23 Package** for space-constrained designs  
- **Wide hFE Range** (60 to 240) for flexibility in circuit design  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

PNP Epitaxial Silicon Transistor

Alternative Part Number

  • 2SA928A --: Original Japanese 2SA-series PNP transistor that the KSA928A is a direct clone of; same low-noise audio characteristics and pinout.
  • BC560C --: Low-noise PNP audio transistor with comparable voltage and current ratings, widely available and suitable for audio preamp stages.
  • 2N5087 --: General-purpose low-noise PNP transistor with similar gain and voltage ratings, usable as a functional substitute in many audio circuits.
  • MPSA56 --: General-purpose PNP transistor with higher voltage rating and similar current capability; usable replacement where slightly different noise/gain characteristics are acceptable.
