Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ150A is a transient voltage suppressor (TVS) diode manufactured by FAIRCHILD. Below are its specifications, descriptions, and features based on factual data from Ic-phoenix technical data files:

### **Specifications:**
- **Peak Pulse Power Dissipation (Pppm):** 400W (10/1000μs waveform)  
- **Standoff Voltage (VWM):** 150V  
- **Breakdown Voltage (VBR):** 166.5V (min) to 184V (max)  
- **Clamping Voltage (VC):** 243V (max) at 1A  
- **Peak Pulse Current (IPP):** 1.65A (8/20μs waveform)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**
- The SMAJ150A is designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive load switching.  
- It is a unidirectional TVS diode, meaning it clamps voltage spikes in one polarity.  
- Compliant with RoHS standards.  

### **Features:**
- **Fast Response Time:** Typically less than 1ps.  
- **Low Leakage Current:** <1μA at standoff voltage.  
- **High Surge Capability:** Handles high transient energy.  
- **Reliable Performance:** Robust construction for industrial applications.  

This information is strictly based on manufacturer-provided data.

Alternative Part Number

  • P6SMB160A --: SMB-packaged unidirectional TVS with comparable 150-160V standoff and clamping performance, widely available and a common drop-in for SMAJ150A.
  • 1SMB150A --: SMB unidirectional TVS diode with 150V standoff and similar surge rating, from a different series and manufacturer, suitable as a functional replacement.
  • SMBJ150A --: SMB unidirectional TVS with 150V standoff and 600W peak pulse power, matching the SMAJ150A rating class in a different product family.
  • P6SMB150A --: Same 150V standoff unidirectional TVS in SMB package with comparable clamping voltage and peak pulse power, widely available and pin-compatible.
  • 1SMB150AT3G --: SMB 150V unidirectional transient voltage suppressor with equivalent standoff and breakdown voltage, suitable drop-in replacement from another manufacturer.
