The 287V maximum clamping voltage at 1.7A peak pulse current sets the upper bound the downstream circuitry must survive — a 160V-rated capacitor or MOSFET with a 300V Vds margin would be adequate. No power line protection (bidirectional) — this is a unidirectional device intended for DC rails where the transient polarity is known. ## Active production — ordering the exact code The base product number is SMAJ160; the suffix indicates lead-free / RoHS-compliant construction.","metaTitle":"SMAJ160E3/TR13 TVS Diode – 160V, 500W, DO-214AC","metaDescription":"SMAJ160E3/TR13 Zener TVS diode, 160V reverse standoff, 500W peak pulse power, DO-214AC (SMA) surface mount.

For a 24V system, select a TVS with a reverse standoff near 24V (e.g., SMAJ24A). Using a 160V-rated part would leave the 24V rail unprotected because the breakdown threshold is 178V, well above any transient the 24V bus would see."},{"question":"Is SMAJ160E3/TR13 RoHS compliant?","answer":"Yes — the suffix in the ordering code indicates Microchip's lead-free / RoHS-compliant finish.
