Features

The STTH112U is a high-efficiency ultrafast diode with the following key features:
- Voltage Rating: 1200V
- Current Rating: 10A average forward current
- Ultrafast Recovery: Low reverse recovery time (typically 35ns)
- Low Forward Voltage Drop: ~1.7V (reduces power losses)
- High Surge Current Capability: Robust performance under transient conditions
- TO-220AC Package: Easy mounting and heat dissipation
- Applications: Used in power supplies, inverters, snubber circuits, and freewheeling diodes
Its fast switching and low losses make it ideal for high-frequency circuits.

Pinout

The STTH112U is a dual ultrafast diode in a SMB (DO-214AA) package.
- Pin Count: 2 (anode and cathode for each diode, common cathode configuration).
- Function: Designed for high-efficiency rectification in switching power supplies, freewheeling, and reverse battery protection.
- Key Features:
- Ultrafast recovery (trr ≤ 35 ns).
- Low forward voltage drop (VF ≈ 0.95V at 1A).
- High surge current capability.
- Voltage rating: 200V (STTH112U).
Commonly used in SMPS, inverters, and automotive applications.
