Clamp voltage is 77.4V maximum at the 19.4A peak pulse current — the figure to budget for downstream device stress. The breakdown voltage min of 53.3V ensures the device starts conducting before the protected circuitry sees a damaging overvoltage. ## Package, mounting, and temperature range Microchip Technology continues production.","metaTitle":"SMCJ48CAE3/TR13 – Microchip 1500W Bidirectional TVS Diode","metaDescription":"Active-production SMCJ48CAE3/TR13 Zener TVS, 1500W peak pulse, 48V reverse standoff, DO-214AB SMC package.

Both share the same 48V standoff and 1500W peak pulse rating, but the bidirectional variant clamps both polarities. If the original design uses a unidirectional part, confirm the circuit can tolerate the symmetrical breakdown characteristic before substituting."},{"question":"What is the difference between SMCJ48CAE3/TR13 and SMCJ48CA/TR13?","answer":"The '' suffix on SMCJ48CAE3/TR13 indicates Microchip's lead (Pb)-free and RoHS-compliant finish. The non- variant (SMCJ48CA/TR13) may contain lead in the solder plating.
