Features

The SM6T33A is a 33V unidirectional TVS diode designed for transient voltage suppression in sensitive electronics. Key features:
- Voltage Ratings: Standoff voltage 28.1V, breakdown voltage 31.2V, clamping voltage 53.3V (at 24.2A).
- High Surge Protection: Handles 24.2A peak pulse current (8/20µs).
- Low Leakage: 1µA max at standoff voltage.
- Fast Response: Reacts in <1ns to transients.
- Package: SMB (DO-214AA) for compact PCB mounting.
- Applications: Protects automotive, industrial, and telecom systems from ESD, lightning, and inductive spikes.
Ideal for safeguarding power lines, data interfaces, and communication ports against overvoltage events.

Pinout

The SM6T33A is a transient voltage suppressor (TVS) diode designed for ESD and surge protection.
- Pin Count: 2 pins (unidirectional) or 3 pins (bidirectional variant, if applicable).
- Function: Clamps transient voltages (up to 33V breakdown voltage) to protect sensitive electronics from surges, ESD, and lightning.
- Key Features:
- Peak Pulse Power: ~600W (8/20μs waveform).
- Low Clamping Voltage.
- RoHS compliant.
Commonly used in power lines, data interfaces (USB, HDMI), and automotive circuits.
