Zener TVS diode, 1.5SMCJ series, bidirectional, 110V standoff, 122V breakdown min, 177V clamping @ 8.4A, 1500W peak pulse, -55°C to 150°C junction, SMC (DO-214AB) surface-mount, tape & reel.","salesMarkdown":"## What a 1.5SMCJ TVS does in your circuit The 1.5SMCJ110CA_R1_00001 is a bidirectional Zener-based transient voltage suppressor — it sits on a supply rail and stays invisible until a voltage spike exceeds the breakdown threshold, at which point it clamps the event to a defined voltage and shunts the surge current away from downstream circuitry. The reverse standoff of 110 V defines the working voltage the diode ignores in normal operation; the minimum breakdown of 122 V is the trigger point; the clamping maximum of 177 V at a peak pulse current of 8.4 A is what the downstream circuit sees during the transient event. The 1500 W peak pulse rating is measured at the standard 10/1000 µs waveform — a slow-rise, slow-decay surge typical of switching transients and inductive load dump. The 8.4 A peak pulse current at that waveform tells you the diode is sized for secondary-surge protection on 110 V nominal lines, not for primary lightning-surge columns where peak currents run far higher. If your target waveform is shorter (8/20 µs) the clamping voltage and effective peak current shift — check the V-I curve in the Panjit datasheet for the specific waveform in your application. ## Junction temperature range and thermal margin The thermal resistance from junction to ambient is package-dependent; the SMC (DO-214AB) body style shares the same footprint as the common SMA package but with a higher current rating, so the land pattern and thermal pad treatment follow standard SMC layout practice.","metaTitle":"Panjit 1.5SMCJ110CA_R1_00001 TVS Diode, 177V Clamping","metaDescription":"Bidirectional Zener TVS diode, 110V standoff, 122V breakdown min, 177V clamping at 8.4A peak pulse, 1500W peak, -55 to 150°C, SMC (DO-214AB).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Panjit International Inc.","Type":"Zener","Series":"1.5SMCJ","Package":"Tape & Reel (TR) Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC (DO-214AB)","Voltage - Breakdown (Min)":"122V","Voltage - Clamping (Max) @ Ipp":"177V","Voltage - Reverse Standoff (Typ)":"110V","Current - Peak Pulse (10/1000µs)":"8.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a271c765b4bf7e62ca251a7791548580.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative in the 1.5SMCJ series?","answer":"The 1.5SMCJ series spans multiple standoff voltage ratings across the same SMC (DO-214AB) footprint with identical pinout — selecting an alternative requires matching the standoff voltage to your working rail.
