DiodesZetex Uni-Directional TVS Diode 600 W, 2-Pin Surface Mount DO-214 SMBJ20A-13-F

DiodesZetex SMBJ20A-13-F is a high-performance uni-directional transient voltage suppressor (TVS) diode designed for protection against voltage transients and surges in electronic circuits. With a peak pulse power dissipation rating of 600 watts, this diode is engineered to safeguard sensitive components from voltage spikes that could otherwise cause irreversible damage.

The device features a compact and durable DO-214 surface-mount package with a 2-pin configuration, which facilitates easy assembly on printed circuit boards (PCBs) and minimizes board space utilization. Its electrical characteristics include a minimum breakdown voltage of 22.2 V and a maximum reverse stand-off voltage of 20 V, ensuring effective voltage clamping at 32.4 V during transient events.

Operating reliably across a broad temperature range from -55°C to 150°C, the SMBJ20A-13-F model is suitable for industrial, automotive, and commercial electronic applications where robust transient voltage protection is essential. Its low maximum reverse leakage current of 5 μA further ensures minimal impact on circuit performance when operating under normal voltages.

The diode’s design supports a maximum peak pulse current of 18.5 A, allowing it to absorb significant energy pulses without failure, thus enhancing system reliability. This performance combined with the single-element uni-directional topology makes it ideal for protecting DC power lines, data lines, and signal lines from transient overvoltage conditions.

This product carries no specific automotive or industry certifications but is built to comply with general semiconductor standards. Applications include power supplies, telecommunication equipment, industrial control systems, automotive electronics, and consumer devices requiring heightened surge protection.
