Littelfuse 1-Element Uni-Directional TVS Diode, 5 kW Peak Pulse Power, Surface Mount DO-214 Package 5.0SMDJ33A

Littelfuse 5.0SMDJ33A is a high-performance 1-element uni-directional transient voltage suppression diode, engineered to protect sensitive electronic equipment from voltage transients such as lightning-induced surges and switching spikes. This device is packaged in a compact surface mount DO-214 package allowing for optimal board space utilization.

Capable of handling a peak pulse power dissipation of 5 kW at the 10x1000μs waveform, the 5.0SMDJ33A features a minimum breakdown voltage of 36.7 V and a maximum reverse stand-off voltage of 33 V, providing excellent surge protection. It exhibits a low clamping voltage of typically 53.3 V and a fast response time typically less than 1.0 picosecond, which ensures rapid suppression of transient voltage events to safeguard downstream circuitry.

Designed with a single diode configuration, it offers uni-directional voltage protection with strong ESD resilience and low maximum reverse leakage current of 5 μA above 22 V to minimize power dissipation during normal operation. The device is built with a glass passivated chip junction and features built-in strain relief ensuring mechanical and thermal reliability.

Operating within a broad temperature range from -65°C up to 150°C, this diode is suitable for demanding industrial and commercial electronics, including power supplies, telecommunications, and automotive electronic systems where transient suppression is critical. The matte tin lead-free plating supports high-temperature soldering cycles at 260°C for up to 40 seconds, facilitating durable assembly in manufacturing processes.

Littelfuse 5.0SMDJ33A is halogen-free and RoHS compliant, reflecting an environmentally responsible design with excellent clamping capability and minimal incremental surge resistance. Applications include circuit board protection in consumer electronics, industrial instrumentation, HVAC control systems, and other sensitive electronic equipment where voltage surge protection is mandatory.
