Description and Introduction

BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS The TISP4300M3BJR is a solid-state protector designed for telecommunications applications. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
- Bourns  

### **Description:**  
- The TISP4300M3BJR is a **three-terminal solid-state overvoltage protector** used to safeguard sensitive telecom equipment from voltage transients, such as lightning strikes and power cross events.  

### **Features:**  
1. **High Surge Current Capability** – Handles high transient currents.  
2. **Low Capacitance** – Minimizes signal distortion, making it suitable for high-speed data lines.  
3. **Fast Response Time** – Quickly clamps transient voltages to protect downstream components.  
4. **Three-Terminal Configuration** – Protects between tip, ring, and ground in telecom applications.  
5. **Solid-State Silicon Technology** – Provides reliable, long-term protection without wear-out mechanisms.  
6. **RoHS Compliant** – Meets environmental standards.  

### **Key Specifications:**  
- **Breakdown Voltage (VBR):** 300 V (typical)  
- **Clamping Voltage (VC):** 700 V (max at 100 A)  
- **Peak Surge Current (IPP):** 100 A (8/20 µs waveform)  
- **Capacitance (CT):** Typically 50 pF (low for high-frequency applications)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Applications:**  
- **Telecommunication Line Protection** (e.g., DSL, T1/E1, ISDN)  
- **Network Interface Devices (NIDs)**  
- **Central Office Equipment**  

For detailed electrical characteristics and application notes, refer to the official Bourns datasheet.

Application Scenarios & Design Considerations

BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS

Alternative Part Number

  • P3100SCLRP --: Thyristor surge protection device in the same SMB/DO-214AA package with comparable 300V-class breakover voltage, suitable as a functional replacement for telecom overvoltage protection.
  • TISP4350M3BJR --: Same TISP series family with slightly higher breakover voltage rating; electrically close and pin-compatible, but verify clamping voltage margin in the target circuit.
  • P3500SCLRP --: SIDACtor-type protector in SMB package with similar surge handling; a viable cross-series alternative when exact TISP4300M3BJR availability is limited.
  • P0300SCMCLRP --: SIDACtor thyristor surge protector in the same overvoltage protection role with comparable voltage and current ratings, from a leading brand in this product family.
  • P3100SBLRP --: Similar SIDACtor surge protection device with matching package style and breakdown voltage class, suitable as a functional replacement.
  • TISP61089BDR-S --: Bourns TISP series thyristor surge protector with similar clamping behavior and telecom protection characteristics, offering an alternative source.
