At the 207 V clamping voltage, the peak current works out to 7.6 A, which is the current the diode shunts during the transient. The 128 V reverse standoff voltage means this diode sits across a 120 V nominal rail and stays off until a transient pushes past the 143 V breakdown threshold. It clamps at 207 V maximum, protecting downstream components rated for that voltage or higher. The bidirectional channel handles positive and negative surges equally — useful on AC lines or DC rails where reverse polarity transients are possible. ## DO-214AB package and board-fit realities Surface-mount in a DO-214AB (SMC) package — the larger of the common DO-214 sizes, which means the copper pad on the PCB needs to match the tab footprint for thermal transfer. The junction temperature range is -55°C to 150°C, so it handles hot environments like power supplies or motor drives without derating at the high end. No special handling beyond standard ESD precautions — the part is a two-terminal device with clear cathode band marking, so orientation is obvious even without a bench. ## Active production and sourcing posture Sourced through independent distribution channels.","metaTitle":"1.5SMC150CA R7G TVS Diode, 1500W, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC150CA R7G bidirectional Zener TVS diode, 1500W peak pulse power, 128V standoff, 207V clamp.
