Description and Introduction

DUAL FORWARD-CONDUCTING P-GATE THYRISTORS PROGRAMMABLE OVERVOLTAGE PROTECTORS The TISP61089A is a solid-state overvoltage protector designed for telecommunications applications. Below are the manufacturer specifications, descriptions, and features:

### **Manufacturer Specifications:**
- **Manufacturer:** Bourns (formerly from Texas Instruments)
- **Type:** Thyristor Overvoltage Protector (TISP)
- **Peak Off-State Voltage (VDRM):** 89 V
- **Breakover Voltage (VBO):** 100 V (typical)
- **Maximum Clamping Voltage (VCL):** 135 V at 100 A
- **Maximum Surge Current (IPP):** 100 A (8/20 µs waveform)
- **Holding Current (IH):** 150 mA (minimum)
- **Operating Temperature Range:** -40°C to +85°C
- **Package:** SOT-23 (Surface Mount)

### **Descriptions:**
- The TISP61089A is a bidirectional thyristor-based surge protector designed to safeguard sensitive electronic circuits from overvoltage transients, such as lightning strikes or power surges.
- It is commonly used in telecommunications equipment, DSL modems, and other high-speed data line protection applications.
- The device triggers into a low-voltage state when an overvoltage event occurs, diverting excess current away from the protected circuit.

### **Features:**
- **Bidirectional Protection:** Guards against both positive and negative voltage surges.
- **Fast Response Time:** Quickly clamps transient voltages to safe levels.
- **Low Capacitance:** Minimizes signal distortion in high-frequency applications.
- **High Surge Current Handling:** Capable of withstanding large transient currents (100 A peak).
- **Solid-State Reliability:** No moving parts, ensuring long-term durability.
- **Compact SOT-23 Package:** Suitable for space-constrained PCB designs.

For detailed electrical characteristics and application notes, refer to the official datasheet from Bourns or Texas Instruments.
