Description and Introduction

TECHNICAL SPECIFICATIONS OF SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMCJ90A is a transient voltage suppressor (TVS) diode manufactured by Vishay. Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Peak Pulse Power (10/1000µs):** 1500 W  
- **Standoff Voltage (VWM):** 76.6 V  
- **Breakdown Voltage (VBR):** 85.1 V (min) – 94.2 V (max)  
- **Clamping Voltage (VC):** 137 V at 10 A  
- **Maximum Reverse Leakage Current (IRM):** 1 µA at VWM  
- **Junction Capacitance (CJ):** 1000 pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- The SMCJ90A is designed to protect sensitive electronics from high-voltage transients such as ESD, lightning, and inductive switching.  
- It is a unidirectional TVS diode, meaning it clamps positive voltage transients only.  
- Meets industry standards for surge protection (IEC 61000-4-2, 4-4, 4-5).  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection for sensitive components.  
- **Fast Response Time:** Reacts quickly to transient events (pico-second range).  
- **High Surge Capability:** Can handle large transient currents.  
- **RoHS Compliant:** Environmentally friendly and lead-free.  

This information is strictly based on Vishay's datasheet for the SMCJ90A TVS diode.

Application Scenarios & Design Considerations

Alternative Part Number

  • 1SMC90A --: Same 1500W unidirectional TVS diode with 90V standoff voltage and SMC package, direct functional equivalent.
  • P6SMB90A --: Unidirectional TVS with 90V standoff in SMB package; lower power rating (600W) but usable in less demanding clamping applications.
  • SMAJ90A --: Unidirectional 90V TVS in SMA package; 400W rating suits lower surge requirements and offers a smaller footprint alternative.
  • 1SMC90AT3G --: Unidirectional 1500W TVS diode with 90V standoff in SMC package, directly interchangeable with SMCJ90A.
  • SMDJ90A --: 3000W unidirectional TVS diode with 90V standoff in SMC package; higher surge rating provides margin while remaining electrically compatible for clamping a 90V rail.
  • 1.5SMC90A --: Same 1500W peak pulse power, 90V standoff unidirectional TVS in the SMC (DO-214AB) package; widely available and a direct functional drop-in.
