The SM4T33CAY is a state-of-the-art transient voltage suppression (TVS) diode designed and manufactured by STMicroelectronics, a global leader in semiconductor solutions. This robust device is engineered to protect sensitive electronic circuits from voltage transients induced by system level events such as load dump, lightning, and electrostatic discharge (ESD).
Key Features
- Stand-off Voltage: The SM4T33CAY offers a stand-off voltage of 33V, which is the maximum voltage that the device can tolerate without conducting significant current.
- Peak Pulse Power: It has an impressive peak pulse power dissipation of 400W (10/1000µs), ensuring high power protection for sensitive components against surges.
- Low Clamping Voltage: The device provides a low clamping voltage, which is the maximum voltage drop across the protector when subjected to a peak pulse current.
- Fast Response Time: With a rapid response to transient over-voltages, it ensures that the components in your electronic system are shielded promptly.
- Low Leakage Current: Exhibiting a low leakage current, the SM4T33CAY ensures minimal power loss when the device is in the standby state.
- Compliance: It complies with IEC 61000-4-2 and IEC 61000-4-5 standards, which are related to ESD and surge immunity, respectively.
