STMICROELECTRONICS TVS Low Voltage Transil Diode, Unidirectional, 3.3V, DO-216A
STMICROELECTRONICS 3.3V TVS diode for ESD protection. 200W pulse power, unidirectional, DO-216AA package. For portable electronics.
The STMICROELECTRONICS Low Voltage Transil Diode is a specialised Transit™ diode engineered for the protection of sensitive electronics. Designed for use in portable equipment and miniaturised electronic devices, it offers robust defence against Electrostatic Discharge (ESD) and transient overvoltage events that can cause critical component failure.
This unidirectional diode utilises a high-speed clamping action to divert dangerous voltage spikes away from the protected circuit. With a substantial 200W peak pulse power dissipation (10/1000µs), it can absorb significant transient energy. It features a stand-off voltage of 3.3V and a low clamping factor (VCL/VBR), ensuring the protected line voltage is kept to a safe maximum of 6.8V during an event, safeguarding downstream components.
Its exceptionally fast response time is crucial for reacting to rapid ESD strikes before damage can occur. The component is supplied in a compact, surface-mount DO-216AA (SMB) package outline, which is JEDEC registered, making it suitable for high-density PCB designs common in modern portable electronics.
