Description and Introduction

SMD Type, 6 V - 60 V The SMD1812P075TSA is a PTC resettable fuse manufactured by Bourns.  

### **Specifications:**  
- **Part Number:** SMD1812P075TSA  
- **Type:** PTC Resettable Fuse (Polymeric Positive Temperature Coefficient)  
- **Package:** 1812 (4527 Metric)  
- **Hold Current (I_H):** 0.75A  
- **Trip Current (I_T):** 1.5A  
- **Max Voltage (Vmax):** 30V  
- **Max Current (Imax):** 40A  
- **Power Rating:** 1.2W at 20°C  
- **Resistance (Rmin/Rmax):** 0.08Ω / 0.40Ω  
- **Operating Temperature Range:** -40°C to +85°C  

### **Description:**  
The SMD1812P075TSA is a surface-mount resettable fuse designed to protect circuits from overcurrent conditions. It automatically resets when the fault is removed, eliminating the need for replacement.  

### **Features:**  
- **Resettable:** Returns to a low-resistance state after fault removal.  
- **Surface-Mount Design:** Suitable for automated PCB assembly.  
- **Fast Trip Response:** Quickly responds to overcurrent events.  
- **RoHS Compliant:** Meets environmental standards.  
- **Reliable Overcurrent Protection:** Safeguards sensitive components.  

This information is based on Bourns' official datasheet for the SMD1812P075TSA.

Application Scenarios & Design Considerations

SMD Type, 6 V - 60 V

Alternative Part Number

  • MF-MSMF075-2 --: Same 1812-size resettable PTC fuse with 0.75A hold current and comparable voltage rating; widely available and directly interchangeable.
  • 0ZCG0075BF2B --: 1812 SMD PPTC fuse rated 0.75A hold current, matching form factor and electrical characteristics for drop-in replacement.
  • LVR075S-2 --: PolySwitch-style resettable fuse with 0.75A hold current; similar trip behavior and 1812 footprint, suitable as an alternative.
