Description and Introduction

Surface mount transient voltage suppressor. 1500 watts peak power. Reverse stand-off voltage VRWM = 150 V. Test current IT = 1 mA. The SMCJ150A is a Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronics from voltage transients and surges.  

### **Manufacturer:**  
- **Littelfuse** (primary manufacturer)  
- Other manufacturers may include **STMicroelectronics**, **Vishay**, or **ON Semiconductor** (check datasheets for exact sourcing).  

### **Specifications:**  
- **Voltage Rating (V₃ᵣₘ):** 150V  
- **Breakdown Voltage (V₆ᵣ):** 166.5V (min) – 184V (max)  
- **Peak Pulse Power (Pₚₚₘ):** 1500W (10/1000μs waveform)  
- **Standoff Voltage (Vᵣᵥₘ):** 150V  
- **Clamping Voltage (Vc):** 243V (at 10A)  
- **Maximum Reverse Leakage Current (Iᵣ):** 1µA  
- **Junction Capacitance (Cj):** ~100pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**  
- **Type:** Unidirectional TVS diode (clamps positive transients only).  
- **Package:** DO-214AB (SMC) surface-mount package.  
- **Application:** Protects circuits from ESD, lightning, and inductive load switching.  

### **Features:**  
- High surge capability (1500W peak pulse power).  
- Fast response time (<1ns).  
- Low clamping voltage for effective protection.  
- RoHS compliant.  

For exact specifications, always refer to the manufacturer’s datasheet.

Application Scenarios & Design Considerations

Surface mount transient voltage suppressor. 1500 watts peak power. Reverse stand-off voltage VRWM = 150 V. Test current IT = 1 mA.

Alternative Part Number

  • 1.5SMC150A --: Same 1500W unidirectional TVS clamping voltage class in a different series naming, widely available and drop-in compatible.
  • P6SMB150A --: 600W SMB unidirectional TVS with matching 150V standoff and similar clamping, suitable when lower power rating is acceptable.
  • SMAJ150A --: 400W SMA unidirectional TVS with the same 150V standoff voltage, usable for lower-surge applications with smaller footprint.
  • TPSMB150A --: Automotive-grade 600W SMB unidirectional TVS with 150V standoff; good alternative when AEC-Q101 qualification or higher reliability is required.
