Description and Introduction

HSMP-3894 · PIN switch diode The HSMP-3894 is a surface mount PIN diode manufactured by HP (Hewlett-Packard). Here are its key specifications:

1. **Type**: PIN Diode  
2. **Package**: SOT-23  
3. **Applications**: RF switching, attenuation, and modulation  
4. **Frequency Range**: Up to 3 GHz  
5. **Forward Voltage (VF)**: Typically 1V at 10 mA  
6. **Reverse Breakdown Voltage (VR)**: 50V minimum  
7. **Capacitance (CT)**: Typically 0.25 pF at 0V, 1 MHz  
8. **Reverse Recovery Time (trr)**: Typically 1 μs  
9. **Operating Temperature Range**: -65°C to +150°C  

These specifications are based on historical HP datasheets for the HSMP-3894. For exact details, refer to the official documentation.

Application Scenarios & Design Considerations

HSMP-3894 · PIN switch diode

Alternative Part Number

  • BAT15-099 --: Silicon Schottky diode in SOT-23 with similar low capacitance and fast switching, suitable replacement for HSMP3894 in RF detector and mixer circuits.
  • HSMS-2850 --: Zero-bias Schottky detector diode from the same HP/Avago lineage, pin-compatible in many RF detection applications and widely available.
  • SMS7630-079 --: Low-barrier Schottky diode with comparable RF characteristics and SOT-23 package, commonly used as a drop-in alternative for HP Schottky detector diodes.
