Description and Introduction

Transistor for low frequency small-signal amplification 2 in 1 The part HN1A01FE is manufactured by TOSHIBA. It is a photocoupler (optocoupler) with the following specifications:  

- **Type**: Photocoupler with a GaAlAs infrared LED and a phototransistor  
- **Isolation Voltage**: 5000 Vrms (min)  
- **Collector-Emitter Voltage (VCEO)**: 80 V  
- **Current Transfer Ratio (CTR)**: 50% (min) at IF = 5 mA, VCE = 5 V  
- **Input Forward Current (IF)**: 50 mA (max)  
- **Operating Temperature Range**: -55°C to +110°C  
- **Package**: DIP4 (4-pin Dual In-line Package)  

This device is commonly used for signal isolation in electronic circuits.
