Description and Introduction

TVS Diode Array For ESD and Latch-Up Protection The SMF12.TCT is a Transient Voltage Suppressor (TVS) diode manufactured by SEMTECH. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Peak Pulse Power (PPP):** 400W (8/20µs waveform)  
- **Breakdown Voltage (VBR):** 12V (min)  
- **Standoff Voltage (VRWM):** 10V  
- **Clamping Voltage (VC):** 19.9V at 1A (IPP)  
- **Maximum Reverse Leakage Current (IR):** 1µA at VRWM  
- **Peak Pulse Current (IPP):** 10.1A (8/20µs)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**
- The SMF12.TCT is a surface-mount TVS diode designed to protect sensitive electronics from voltage transients, such as ESD, lightning, and inductive load switching.  
- It is part of SEMTECH’s SMF series, which offers low clamping voltage and fast response times.  
- The device is compliant with RoHS standards and is available in a DO-219AB (SMF) package.  

### **Features:**
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **Fast Response Time:** Reacts quickly to transient events (sub-nanosecond response).  
- **Surface-Mount Package:** Compact DO-219AB (SMF) package for PCB integration.  
- **High Surge Capability:** Handles high transient currents.  
- **RoHS Compliant:** Environmentally friendly and lead-free.
