Description and Introduction

HSMP-381F · Low distortion PIN attenuator diode The HSMP-381F is a surface mount PIN diode manufactured by Agilent (now part of Keysight Technologies). Here are its key specifications:

- **Type**: Silicon PIN Diode  
- **Package**: SOT-23  
- **Forward Voltage (VF)**: 1.0V (typical) at 10mA  
- **Reverse Breakdown Voltage (VR)**: 30V (min)  
- **Capacitance (Ct)**: 0.25pF (typical) at 0V, 1MHz  
- **Reverse Recovery Time (trr)**: 4ns (typical)  
- **Forward Current (IF)**: 100mA (max)  
- **Power Dissipation (Pd)**: 250mW (max)  

It is designed for high-speed switching, attenuation, and RF applications.
