Taiwan Semiconductor 1-Element Uni-Directional TVS Diode 1.5 kW 2-Pin DO-214 SMCJ43A

Taiwan Semiconductor SMCJ43A is a 1-Element Uni-Directional Transient Voltage Suppressor (TVS) Diode offering 1.5 kW peak pulse power dissipation. Housed in a compact 2-Pin DO-214 surface mount package, it provides reliable transient protection for sensitive electronic circuits.

With a minimum breakdown voltage of 47.8 V and maximum reverse stand-off voltage of 43 V, the SMCJ43A effectively clamps voltage spikes up to 69.4 V, protecting circuits from damage due to voltage surges. The diode operates within a wide temperature range from -55°C to 150°C, suitable for diverse industrial and automotive environments.

This device features a single diode configuration with a glass-passivated junction ensuring enhanced durability and stability under high stress. The maximum peak pulse current of 21.6 A allows it to absorb large transient currents efficiently, while its fast response time and low incremental surge resistance ensure optimum surge suppression performance.

The compact dimensions (7.15 mm length, 6.25 mm width, 2.75 mm height) enable space-saving on printed circuit boards, supporting modern high-density electronic designs. The SMCJ series compliance with FBI standards and UL certification (#E258596) as well as UL94V-0 flammability classification assures quality and safety standards compliance.
