A 5 kW device in R-6 axial package is typically deployed at the board entry point on 24 V power rails, protecting downstream ICs from EFT and surge events that exceed the downstream supply's absolute-maximum rating. The reverse standoff of 22 V sets the normal operating bias — the TVS stays in high-impedance mode and does not conduct until the transient pushes the line above 24.4 V breakdown. ## Single-channel unidirectional — clamping direction matters One bidirectional channel sounds like it handles both polarities, but in TVS nomenclature a bidirectional-channel count of 1 indicates a unidirectional device — it clamps one polarity only. The other polarity is protected only if the circuit ground reference naturally absorbs it or a complementary TVS is placed on the opposite rail. In a 24 VDC power path this is usually fine; in an AC-coupled signal line a unidirectional TVS will not protect negative-going transients. Confirm the clamping direction against the actual fault scenario before committing the BOM line. ## R-6 axial package and through-hole mounting R-6 axial package mounts in standard 0.025 inch lead dia holes on a 0.300 inch lead spacing — the same footprint as DO-201AD. The axial lead form factor allows heat sinking through the leads into the PCB copper; no thermal pad or exposed paddle is involved. Tape & Box packaging is the standard reel-free option for through-hole components and matches the automated axial insertion equipment common in power-supply and protection-module assembly. The 150 °C maximum junction temperature rating places this device in the industrial/military temperature band — the upper limit is set by the junction-to-lead thermal resistance and the maximum allowable case temperature for the Zener junction. At the 5 kW peak pulse rating the transient thermal impedance matters: repeated high-energy pulses close together can accumulate junction heat. For a continuous 24 V rail with infrequent surge events the temperature margin is adequate; for a motor drive output stage with repetitive transients the designer should check the pulse-derating curve in the Comchip datasheet before committing to full load. The -55 °C low end covers cold-start and outdoor equipment deployment.","metaTitle":"Comchip 5KP22CA-G TVS Diode, 5kW Peak Pulse, 22V Standoff","metaDescription":"Comchip 5KP22CA-G unidirectional TVS diode, 5kW peak pulse, 22V standoff, 35.5V clamping, R-6 axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Comchip Technology","Type":"Zener","Series":"-","Package":"Tape & Box (TB)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"R-6, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"5000W (5kW)","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"R-6","Voltage - Breakdown (Min)":"24.4V","Voltage - Clamping (Max) @ Ipp":"35.5V","Voltage - Reverse Standoff (Typ)":"22V","Current - Peak Pulse (10/1000µs)":"140.85A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5352","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f17d96ee753176076f08e0ee812e523.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 5KP22CA-G and how do I get a price?","answer":"Quantity breaks and full-lot traceability are available on request."},{"question":"What is 5KP22CA-G used for?","answer":"The 5KP22CA-G is a unidirectional Zener-based TVS diode for general-purpose transient voltage suppression on 24 V power rails.
