Description and Introduction

HSMP-4890 · Low inductance PIN switch diode The part HSMP-4890 is manufactured by Agilent (now part of Keysight Technologies). It is a PIN diode designed for high-speed switching applications. Key specifications include:

- **Type**: PIN Diode
- **Package**: SOT-23
- **Reverse Voltage (Vr)**: 50V  
- **Forward Current (If)**: 100mA  
- **Capacitance (Ct)**: 0.25pF (typical at 0V, 1MHz)  
- **Forward Voltage (Vf)**: 1V (typical at 10mA)  
- **Reverse Recovery Time (trr)**: 4ns (typical)  
- **Operating Temperature Range**: -55°C to +150°C  

This diode is commonly used in RF and microwave switching, attenuation, and modulation applications.  

(Note: Agilent's semiconductor division became part of Avago Technologies in 2005, which later merged with Broadcom. However, legacy datasheets may still reference Agilent.)
