- **Package:** SOT-23  
- **Collector-Emitter Voltage (Vceo):** 12V  
- **Collector Current (Ic):** 100mA  
- **Power Dissipation (Pd):** 200mW  
- **DC Current Gain (hFE):** 100 (min)  
- **Transition Frequency (fT):** 250MHz  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**  
The ZC831BTA is a high-performance NPN transistor designed for general-purpose amplification and switching applications. It features low saturation voltage and high current gain, making it suitable for low-power circuits.  

### **Features:**  
- High current gain (hFE)  
- Low saturation voltage  
- Fast switching speed  
- Small SOT-23 package for space-constrained designs  
- Suitable for RF and low-noise applications

Application Scenarios & Design Considerations

SILICON 28V HYPERABRUPT VARACTOR DIODES

Alternative Part Number

  • BAT54 --: Schottky diode in SOT-23 with similar low forward voltage and fast switching, widely available and pin-compatible for many small-signal applications.
  • 1N5711 --: Small-signal Schottky diode with low capacitance and fast switching, suitable as a functional substitute where the ZC831BTA is used for signal detection or clamping.
  • BAS40 --: General-purpose Schottky diode in SOT-23 offering comparable current rating and low forward drop, a common cross-reference for small Zetex Schottky parts.
