STMicroelectronics 1-Element Bi-Directional TVS Diode Surface Mount DO-214 Package 1.5 kW Peak Pulse Power SMCJ33CA-TR

STMicroelectronics SMCJ33CA-TR is a high-performance 1-Element Bi-Directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from transient overvoltages and electrostatic discharges. Rated for a peak pulse power dissipation of 1.5 kW, the device supports efficient absorption of transient surges, safeguarding circuits in industrial, commercial, and consumer electronics applications.

This diode is constructed for surface mount applications utilizing a DO-214 package that optimizes PCB space and simplifies assembly processes. It features a bi-directional configuration, enabling protection against voltage surges in both polarities, and supports a broad operating temperature range from -55°C to 150°C, allowing use in harsh environments.

With precise electrical characteristics including a minimum breakdown voltage of 36.7 V, maximum reverse stand-off voltage of 33 V, and a low clamping voltage of 53.3 V, the SMCJ33CA-TR reliably clamps high surge currents up to 29 A peak pulse current. The minimal maximum reverse leakage current of 1 μA minimizes impact on normal circuit operation.

The compact form factor with measurements of 7.15 mm height, 6.25 mm width, and 2.25 mm length ensures ease of integration into space-constrained designs. This TVS diode complies with Transil™ standards for transient voltage suppression and is intended for deployment in applications requiring electrostatic discharge protection compliant with IEC 61000-4-2.
