Littelfuse Uni-Directional TVS Diode 400 W Power 2-Pin DO-214 SMAJ33A

Littelfuse SMAJ33A is a uni-directional TVS diode designed for transient voltage suppression in electronic circuits. This device is capable of dissipating peak pulse power of 400 W, making it suitable for protecting sensitive components against voltage spikes and surges in industrial, electronic, and commercial applications.

The diode features a robust single-element configuration in a compact 2-pin DO-214 surface mount package, allowing for easy integration on printed circuit boards where space is limited. With a minimum breakdown voltage of 36.7 V and a maximum reverse stand-off voltage of 33 V, it effectively clamps voltage transients to safe levels.

Its electrical parameters include a clamping voltage of 53.3 V and a maximum peak pulse current rating of 7.5 A, ensuring reliable protection against electrostatic discharge (ESD) and transient overvoltages. The operating temperature range from -65°C to 150°C allows usage in various temperature-sensitive environments without performance degradation.

Physically, the small dimensions (4.5 mm length, 2.79 mm width, 2.087 mm height) and low maximum reverse leakage current of 1 μA support high efficiency and low power loss in circuits. This product does not conform to automotive standards but is widely applicable in industrial and consumer electronics for surge protection.

Typical use cases include power supply protection, signal line protection, and safeguarding semiconductor devices in manufacturing, instrumentation, and communication equipment. This diode features a uni-directional single-element configuration.
