Product Description
Littelfuse SMCJ33A is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed for surface mount applications requiring transient voltage suppression up to 1.5 kW peak pulse power dissipation. The device is housed in a DO-214 package featuring two pins for PCB mounting.
Engineered to protect sensitive electronic circuits from transient voltage spikes, this TVS diode offers a minimum breakdown voltage of 36.7 V and a maximum reverse stand-off voltage of 33 V, providing superior clamping at 53.3 V. It supports a broad operating temperature range of -65°C to 150°C, making it suitable for demanding industrial, automotive (non-automotive standard), telecommunications, and consumer electronics applications.
The SMCJ33A device exhibits a maximum peak pulse current of 28.2 A, ensuring robust transient voltage suppression, and has a very low maximum reverse leakage current of 1 μA to maximize efficiency. Its compact form factor with 7.11 mm length, 6.22 mm width, and 2.417 mm height allows integration into densely packed circuit boards.
Electrostatic Discharge (ESD) protection is included, enhancing device durability in environments where electrostatic events occur. The device complies with Littelfuse's high-quality manufacturing standards and is part of the SMCJ series of TVS Diodes.
Designed for surface mount placement with a compact DO-214 case. Single element diode configuration for uni-directional transient protection. 1500 W (1.5 kW) peak pulse power capacity at 10/1000 µs waveform. Operating temperature range from -65°C to 150°C.
Clamping voltage effectively limits voltage transients to protect circuits. Low leakage current reduces power consumption. Suitable for industrial, laboratory, telecommunications, and commercial electronics.
This Littelfuse SMCJ33A diode is an essential component in electronics requiring reliable transient voltage suppression for operational safety and longevity. Explore more from Littelfuse and related categories at EnvMart for comprehensive electronic component selection.
