The reverse standoff voltage of 70.1 V defines the continuous working voltage the diode can hold off without conduction; the circuit must never bias it above this in normal operation. Breakdown starts at 77.9 V minimum — this is where the TVS snaps into avalanche and begins clamping. The 10/1000 µs shape is the standard IEC 61000-4-5 surge waveform, so the 1.5 kW rating is directly comparable to the test level your end equipment must pass. ## Peak pulse capability and what the 1.5 kW figure decides Peak pulse power of 1500 W (1.5 kW) is the product of clamping voltage and peak pulse current at the stated waveform — it tells you the surge energy the device can absorb without degradation. This is the primary selection parameter for a TVS in a protection chain: the upstream clamp must survive the surge that the downstream load cannot. As ambient approaches the upper end, the clamping voltage characteristic shifts per the datasheet temperature coefficient; for precision over-voltage detection, this shift is a board-level design consideration. ## Package, mounting, and application fit The DO-214AB (SMC) package is the standard surface-mount footprint for 1.5–3 kW TVS diodes — the cathode bar in the center of the package marks the unidirectional polarity. Recommended pad layout matches the anode and cathode pads to the thermal impedance of the die; the SMC's exposed die-attach paddle gives better thermal cycling performance than the smaller SMC variants used below 1 kW. Listed as general-purpose — this covers power-supply input protection, signal-line transient suppression, and industrial control modules where a 70.1 V working voltage suits 48 V nominal rails with adequate margin. Power-line protection is flagged No, meaning it is not rated for direct AC line attachment; use a specific AC-line TVS series for that position. Single bidirectional channel — the CA suffix designates the bidirectional polarity direction across the cathode and anode. Polarity matters: reverse-bias the cathode relative to the anode for normal standby; the TVS fires in the forward direction only if the transient reverses polarity through the protection node. Carries an Active lifecycle status from Vishay General Semiconductor — production is not flagged for discontinuation or last-time-buy on the current record. No official successor order code appears in the ledger for the 1.5SMC82CA base number. Sourced to order against BOM quantity through independent distribution channels.","metaTitle":"Vishay 1.5SMC82CA-M3/9AT TVS Diode, 70.1V, DO-214AB","metaDescription":"1.5SMC82CA-M3/9AT is a unidirectional TVS (TransZorb) diode, 70.1V standoff, 77.9V min breakdown, 113V clamping at 13.3A.
