Rated for 1500W peak pulse power under the 10/1000µs waveform, the part clamps at 125V maximum when conducting 12A peak pulse current. That clamping voltage is the voltage the protected circuitry must survive — a key number for the downstream component voltage rating selection. ## DO-214AB footprint and temperature range The junction temperature range spans -65°C to 150°C, covering outdoor telecom cabinets, industrial enclosures, and under-hood electronics where ambient temperatures can push 85°C and above. The base product number is SMCJ70; the suffix denotes the lead-free, RoHS-compliant finish. ## Active production — no LTB on record Submit an RFQ against your BOM quantity; the part is sourced to order through our distribution channel.","metaTitle":"SMCJ70E3/TR13 TVS Diode – 70V Standoff, 1500W, DO-214AB","metaDescription":"SMCJ70E3/TR13 Zener TVS, 70V reverse standoff, 125V clamping at 12A, 1500W peak pulse.
