Description and Introduction

NPN Epitaxial Silicon Transistor The KSD882YS is a PNP bipolar junction transistor (BJT) manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Transistor Type:** PNP  
- **Maximum Collector-Base Voltage (VCB):** -30V  
- **Maximum Collector-Emitter Voltage (VCE):** -30V  
- **Maximum Emitter-Base Voltage (VEB):** -5V  
- **Continuous Collector Current (IC):** -3A  
- **Total Power Dissipation (Ptot):** 1.25W  
- **DC Current Gain (hFE):** 60 to 320 (depending on operating conditions)  
- **Operating Junction Temperature (Tj):** -55°C to +150°C  
- **Package Type:** SOT-89  

### **Description:**
The KSD882YS is designed for general-purpose amplification and switching applications. It is suitable for low to medium power circuits and offers good current gain and saturation characteristics.

### **Features:**
- High current capability (up to 3A)  
- Low saturation voltage  
- Complementary NPN type available (KSC2383YS)  
- Compact SOT-89 surface-mount package  
- Suitable for switching and amplification in consumer electronics, power management, and industrial applications  

For detailed electrical characteristics, refer to the official datasheet from ON Semiconductor (formerly Fairchild).

Application Scenarios & Design Considerations

NPN Epitaxial Silicon Transistor

Alternative Part Number

  • 2SD882 --: Original Japanese 2SD882 NPN power transistor that the KSD882 is a clone of; same 30V/3A ratings and TO-126 package, direct drop-in replacement.
  • MJE172 --: PNP complementary is not suitable, but MJE172 is a widely available NPN 60V/3A TO-126 transistor with higher voltage margin and similar current gain, usable in most KSD882 applications.
  • BD137 --: NPN 60V/1.5A TO-126 audio/power transistor; lower current rating but adequate for many low-power circuits and readily available as a general substitute.
  • BD241C --: NPN power transistor rated 3A/100V in TO-220, offering higher voltage margin and similar switching performance.
