Description and Introduction

SMALL SIGNAL SCHOTTKY DIODES The part **TMMBAT42FILM** is manufactured by **STMicroelectronics (ST)**. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Type:** Schottky Barrier Diode  
- **Package:** SOD-123FL (Miniature Surface Mount)  
- **Maximum Reverse Voltage (VR):** 30V  
- **Average Forward Current (IF):** 200mA  
- **Peak Forward Surge Current (IFSM):** 1A  
- **Forward Voltage Drop (VF):** 0.38V (at 100mA)  
- **Reverse Leakage Current (IR):** 0.5µA (at VR = 25V)  
- **Junction Temperature (TJ):** -65°C to +125°C  
- **Storage Temperature (TSTG):** -65°C to +150°C  

### **Description:**  
The **TMMBAT42FILM** is a Schottky barrier diode designed for high-speed switching applications. It features low forward voltage drop and fast switching characteristics, making it suitable for power management, reverse polarity protection, and signal clamping in compact electronic circuits.  

### **Features:**  
- **Low Forward Voltage Drop** (enhances efficiency)  
- **Fast Switching Speed** (ideal for high-frequency applications)  
- **Miniature SOD-123FL Package** (saves PCB space)  
- **High Surge Current Capability** (robust performance)  
- **AEC-Q101 Qualified** (for automotive applications)  

This information is sourced from STMicroelectronics' official documentation. For detailed application notes, refer to the manufacturer's datasheet.

Application Scenarios & Design Considerations

SMALL SIGNAL SCHOTTKY DIODES

Alternative Part Number

  • BAS42 --: Small-signal Schottky diode with similar 40V/200mA ratings and low forward voltage, suitable drop-in replacement in most circuits.
  • 1N5711 --: Schottky diode with comparable low forward voltage and fast switching, widely available and electrically similar for signal detection.
  • BAT42 --: Direct equivalent Schottky barrier diode with same 40V/200mA class ratings, commonly used as an alternative to the ST part.
  • BAT43 --: Schottky diode in the same family with slightly higher current capability, often used as a drop-in substitute for BAT42 applications.
