Littelfuse SMBJ33CA is a 1-element bi-directional transient voltage suppression (TVS) diode designed for protecting sensitive electronic circuitry from voltage spikes and transient surges. It features a single diode configuration in a compact 2-pin DO-214 surface mount package, capable of dissipating peak pulse power of 600 W. The device's rated minimum breakdown voltage of 36.7 V and maximum reverse stand-off voltage of 33 V provide effective surge protection while clamping voltage limits voltage spikes to 53.3 V.
The diode supports an operating temperature range from -65°C up to 150°C, ensuring stable performance across harsh environmental conditions. With an ESD protection capability and a maximum peak pulse current of 11.3 A, the SMBJ33CA is suitable for industrial and consumer electronics applications requiring robust transient overvoltage protection.
Compact physical dimensions (4.57 mm length, 3.94 mm width, 2.237 mm height) enable space-saving PCB design. The device is RoHS compliant and fits seamlessly into electronic manufacturing and repair contexts where fast and reliable TVS diodes are essential.
Key applications include protection of power supplies, data lines, and communication interfaces in automotive, industrial control, and consumer electronic devices. Single diode, bi-directional for effective transient voltage suppression.
600 W peak pulse power dissipation for high surge tolerance. Surface mount DO-214 package for compact PCB integration. Wide operating temperature range ensures reliability under diverse conditions. ESD protection safeguards sensitive semiconductor components.
