1500W peak pulse power, 5V rail clamp
The SMCJ5.0AE3/TR13 is a unidirectional Zener TVS diode from Microchip Technology, rated for 1500W peak pulse power (10/1000µs waveform). It clamps a 5V nominal rail with a breakdown voltage of 6.4V min and a clamping voltage of 9.2V max at 163A peak pulse current. This part is designed for general-purpose transient suppression on low-voltage DC buses, signal lines, and power inputs where a single unidirectional clamp is needed.
Voltage thresholds and pulse current handling
The 5V reverse standoff voltage means the diode does not conduct at normal rail voltage up to 5V. Breakdown starts at 6.4V, and the clamping voltage is held to 9.2V at the full 163A pulse — a tight clamp for a 5V rail, keeping downstream components safe during surges.
Active production, tape-and-reel delivery
Product status is Active, so no last-time-buy pressure. Package is DO-214AB (SMC), a common footprint for 1500W TVS diodes. Surface-mount mounting suits high-volume reflow soldering.
