The 500W peak pulse power rating at 10/1000µs waveform gives you the energy budget for common industrial surge events. ## Unidirectional clamping in a standard SMA footprint This device protects one polarity only (unidirectional,) – the cathode band marks the protected rail, anode to ground. The DO-214AC (SMA) package is a widely used surface-mount outline; the same footprint serves many TVS families, so swapping in a different voltage rating or a bidirectional variant (like SMAJ5.0CA) requires no board change. The 52A peak pulse current at the 10/1000µs waveform tells you the surge current the part can sink before the clamp voltage rises above 9.6V. ## Active production – sourcing via tape and reel","metaTitle":"SMAJ5.0E3/TR13 Zener TVS Diode – 5V Standoff, 500W, DO-214AC","metaDescription":"Microchip SMAJ5.0E3/TR13 Zener TVS diode, 5V reverse standoff, 500W peak pulse power, unidirectional, DO-214AC (SMA) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"SMAJ5.0","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AC (SMA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"6.4V","Voltage - Clamping (Max) @ Ipp":"9.6V","Voltage - Reverse Standoff (Typ)":"5V","Current - Peak Pulse (10/1000µs)":"52A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7b3ddece4863b4621debe180df56adc8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SMAJ5.0E3/TR13 RoHS compliant?","answer":"The evidence does not list a RoHS compliance statement.

The SMAJ5.0CA is a bidirectional device – it clamps both positive and negative transients. Both share the same 5V standoff, 500W peak pulse power, and DO-214AC footprint, so they are footprint-compatible but not electrically interchangeable without a circuit review."},{"question":"What is the peak pulse power of SMAJ5.0E3/TR13?","answer":"500W measured with a 10/1000µs waveform.
