Description and Introduction

Photocoupler GaAlAs IRed & Photo-IC The TLP250F is an optocoupler manufactured by Toshiba. Below are its specifications, descriptions, and features based on available factual information:  

### **Manufacturer Specifications:**  
- **Manufacturer:** Toshiba  
- **Type:** Photocoupler (Optocoupler) with built-in IGBT/MOSFET gate drive circuit  
- **Isolation Voltage (Viso):** 2500 Vrms (min)  
- **Supply Voltage (VCC):** 10 V to 35 V  
- **Output Current (IO):** ±1.5 A (peak)  
- **Propagation Delay Time (tPLH / tPHL):** 0.5 µs (max)  
- **Operating Temperature Range:** -40°C to +100°C  
- **Package:** 8-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The TLP250F is a high-speed photocoupler designed for driving power MOSFETs and IGBTs in applications such as motor control, inverters, and power supplies.  
- It integrates a GaAlAs LED optically coupled to a photodetector with a built-in driver circuit.  
- Provides electrical isolation between input and output for safety and noise immunity.  

### **Features:**  
- **High Isolation Voltage:** 2500 Vrms ensures safe operation in high-voltage applications.  
- **High Output Current:** Capable of driving IGBTs and MOSFETs with ±1.5 A peak output.  
- **Fast Switching:** Low propagation delay (0.5 µs max) for high-speed operation.  
- **Wide Supply Voltage Range:** Operates from 10 V to 35 V, compatible with various power systems.  
- **Undervoltage Lockout (UVLO):** Protects the output stage when supply voltage is insufficient.  
- **Compact Package:** 8-pin DIP for easy PCB mounting.  

This information is sourced from Toshiba’s official datasheets and product documentation.

Application Scenarios & Design Considerations

Photocoupler GaAlAs IRed & Photo-IC

Alternative Part Number

  • HCPL-3120 --: Industry-standard 2.5A gate drive optocoupler with the same function and pinout as the TLP250F, widely available and directly interchangeable in most IGBT/MOSFET drive circuits.
  • PC923 --: Optocoupler gate driver with comparable output current and isolation ratings, commonly used as a drop-in replacement for the TLP250 family in inverter and motor drive designs.
  • FOD3180 --: 2.5A high-speed gate drive optocoupler with similar isolation voltage and propagation characteristics, suitable as a functional substitute for the TLP250F.
  • FOD3120 --: 2.5A output gate drive optocoupler with DIP-8 footprint and similar isolation ratings, a common cross-reference for the TLP250 family.
  • FOD3150 --: 2.5A output gate drive optocoupler in DIP-8 offering equivalent drive capability and isolation, suitable as a functional replacement for the TLP250F.
