It clamps transients to 125V maximum at 12A peak pulse current, making it a fit for protecting 48V to 70V DC power buses, telecom lines, and industrial control inputs against surges. The DO-214AB (SMC) package is surface-mount, with a wide operating temperature range from -65°C to 150°C junction, suited for outdoor or under-hood environments where thermal cycling is a factor. The 12A peak pulse current (Ipp) at the clamping voltage gives the actual current the diode will shunt during a surge. If your application has a known source impedance, you can calculate whether the diode will stay within its SOA — for example, a 1000V transient through a 50-ohm source yields 20A, which exceeds this rating, so a higher-power TVS or series resistance would be needed.","metaTitle":"SMCJ70CE3/TR13 TVS Diode – 1500W, 70V, DO-214AB","metaDescription":"SMCJ70CE3/TR13 Zener TVS diode, 1500W peak pulse power, 70V reverse standoff, DO-214AB SMC package.

Both share the same 70V reverse standoff voltage, 1500W peak pulse power, and DO-214AB package. Choose the bidirectional version when the signal or power rail swings both positive and negative relative to ground, such as on AC-coupled lines or bipolar supplies."},{"question":"Is SMCJ70CE3/TR13 RoHS compliant?","answer":"The evidence does not explicitly list RoHS compliance status, but Microchip's standard TVS diodes in this series are typically RoHS-compliant and lead-free.
