The reverse standoff of 64 V defines the normal working rail this diode guards without conduction: the protected circuit runs below 64 VDC, and the diode stays off until a voltage spike pushes it into breakdown above 71.1 V minimum. For a 48 VDC rail, the 64 V standoff gives roughly 33 % headroom above the nominal bus voltage — adequate for most industrial 48 V distributions, but confirm the transient amplitude and energy in the target system exceed the 10/1000 µs 1500 W test level before committing. ## Peak pulse handling and thermal margin 1500 W peak pulse capacity is a single-event rating under the specified waveform — the diode absorbs the transient energy and returns to blocking once the event clears; repeated or overlapping transients above this level will push the junction toward its 150 °C maximum.","metaTitle":"1.5SMCJ64A TVS Diode, 64V Standoff, 103V Clamping, Diotec","metaDescription":"Diotec 1.5SMCJ64A unidirectional TVS Zener, 1500 W peak pulse, 64 V standoff, 103 V clamping, DO-214AB SMC.
