Présentation

Description

The SM6T33CAY is a transient voltage suppressor (TVS) diode designed to protect sensitive electronics from voltage spikes and transients, such as ESD, lightning, and inductive load switching. Key features:
- Breakdown Voltage (VBR): 36.7V (min) to 40.5V (max)
- Clamping Voltage (VC): 53.3V at 10A (typical)
- Peak Pulse Power: 600W (10/1000μs waveform)
- Low Leakage Current: <1μA (at working voltage)
- Bi-directional Protection: Safeguards against both positive and negative surges.
Packaged in a SMB (DO-214AA) surface-mount form factor, it’s ideal for automotive, industrial, and telecom applications where robust surge protection is critical.
For detailed specs, refer to the datasheet from STMicroelectronics or other distributors.

Equivalent

The SM6T33CAY is a 33V TVS diode for surge protection. Equivalent alternatives include:
- ON Semiconductor SMAJ33A
- Littelfuse SMBJ33A
- STMicroelectronics SMBJ33A
- Vishay 1.5SMC33A (higher power)
These are similar in voltage rating and function but check datasheets for exact specs like peak pulse power and package size.

Pinout

The SM6T33CAY is a transient voltage suppressor (TVS) diode in a SMB package, designed for overvoltage protection.
- Pin Count: 2 pins (anode and cathode).
- Function: Protects sensitive electronics from voltage transients (e.g., ESD, surges) by clamping excess voltage to 33V (standoff voltage).
- Key Parameters:
- Breakdown Voltage (VBR): ~36.7V (min).
- Peak Pulse Power: 600W (8/20μs pulse).
- Low Clamping Voltage: Ensures fast response to transient events.
Commonly used in automotive, industrial, and telecom applications for safeguarding power and signal lines.
