Description and Introduction

Zener TVSs The SMCJ33CA is a Transient Voltage Suppressor (TVS) diode manufactured by Microsemi. Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Peak Pulse Power (10/1000μs):** 1500W  
- **Breakdown Voltage (VBR):** 36.7V (min) – 40.5V (max)  
- **Standoff Voltage (VRWM):** 33V  
- **Clamping Voltage (VC):** 53.3V at 10A  
- **Peak Pulse Current (IPP):** 28.1A  
- **Leakage Current (IR):** 1μA (max) at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- The SMCJ33CA is a bidirectional TVS diode designed to protect sensitive electronics from high-voltage transients such as ESD, lightning, and inductive load switching.  
- It is part of the SMCJ series, which offers high surge capability in a compact SMC package.  

### **Features:**  
- **Bidirectional Protection:** Safeguards against both positive and negative transient voltages.  
- **Low Clamping Voltage:** Provides effective protection by limiting voltage spikes.  
- **Fast Response Time:** Responds quickly to transient events (typically in picoseconds).  
- **High Surge Capability:** Capable of handling large transient currents.  
- **RoHS Compliant:** Meets environmental standards.  

This information is strictly based on the manufacturer's datasheet for the SMCJ33CA TVS diode by Microsemi.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1.5SMC33CA --: Same 33V bidirectional TVS in a similar SMC package with comparable 1500W peak pulse rating; widely available and pin-compatible.
  • P6SMB33CA --: Bidirectional 33V TVS with 600W rating in SMB package; suitable drop-in for lower-surge applications and easy to source.
  • SMAJ33CA --: Bidirectional 33V TVS in SMA package with 400W rating; good compact alternative when lower surge capability is acceptable.
  • 1.5SMC36CA --: Bidirectional TVS diode in the 1.5SMC series with a comparable 36V standoff voltage and 1500W peak pulse power, suitable for similar transient protection.
  • P6SMB36CA --: Bidirectional SMB-package TVS diode with 36V standoff and 600W peak pulse power, offering a lower-power alternative in a similar form factor.
  • SMDJ33CA --: 3000W bidirectional TVS in SMC package with 33V standoff voltage; higher surge rating provides margin while remaining footprint-compatible.
