TPSMB33A Description

Short technical summary and product information.

The Littelfuse TPSMB33A is a surface mount TVS Diode designed to protect sensitive electronic equipment from voltage transients. It offers a high peak pulse power dissipation of 600W at a 10/1000 µs waveform and a clamping voltage of 45.7V.

 

This automotive-grade component is AEC-Q101 qualified and features ESD protection up to 30 kV (Air and Contact) per IEC 61000-4-2, and EFT protection per IEC 61000-4-4. Its fast response time, typically less than 1.0 ns, ensures effective suppression of transient events.

 

The TPSMB33A is housed in a DO-214AA (SMB) package, making it suitable for applications where board space optimization is important. It operates within a junction temperature range of -65°C to 175°C and meets MSL Level 1 requirements. The device is RoHS compliant and halogen-free.

 

Ideal for automotive applications, the TPSMB33A protects I/O interfaces, VCC bus, and other vulnerable circuits from lightning-induced transients and other voltage surges.
