Rated for a collector-emitter breakdown voltage of 50 V and a continuous collector current of 800 mA, it dissipates up to 500 mW — figures that define its switching and amplification envelope in low-to-medium power circuits. The DC current gain (hFE) is a minimum of 100 at 150 mA collector current with Vce = 10 V, providing consistent gain margin for driver and relay-coil applications. Vce saturation is specified at 1 V maximum with a base current of 50 mA driving 500 mA collector current — this saturation voltage governs the on-state power loss in switching service. ## Temperature range and leakage performance Operating junction temperature spans -65°C to 200°C, a military-grade range that suits avionics, downhole instrumentation, and engine-bay electronics where ambient extremes exceed commercial limits. Collector cutoff current is a maximum 50 nA at rated voltage — this low leakage keeps the transistor firmly off in high-impedance bias networks and battery-powered sleep circuits where every microamp counts. The TO-18 metal can (supplier device package TO-18) is a hermetic, three-lead through-hole package with the collector connected internally to the case — the metal envelope acts as a heat path and an electrical node, so the PCB layout must account for case potential.","metaTitle":"Microchip 2N2222AL NPN Transistor, 50V, 800mA, TO-18","metaDescription":"Microchip Technology 2N2222AL NPN transistor in TO-18 metal can. 50V Vce breakdown, 800mA Ic, 500mW power, -65°C to 200°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Microchip Technology","Series":"-","Package":"Bulk","Power - Max":"500 mW","Mounting Type":"Through Hole","Package / Case":"TO-206AA, TO-18-3 Metal Can","Product Status":"Active","Transistor Type":"NPN","lifecycle_stage":"eol_hot","Base Product Number":"2N2222","Operating Temperature":"-65°C~200°C(TJ)","Frequency - Transition":"-","Supplier Device Package":"TO-18","Vce Saturation (Max) @ Ib, Ic":"1V @ 50mA, 500mA","Current - Collector (Ic) (Max)":"800 mA","Current - Collector Cutoff (Max)":"50nA","DC Current Gain (hFE) (Min) @ Ic, Vce":"100 @ 150mA, 10V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.2349","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6daf2ff874b65a532d1a51a8a4837500.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 2N2222AL?","answer":"The base product number 2N2222 covers a family of pin-compatible NPN transistors in the TO-18 package; the 2N2222AL is Microchip's specific variant."},{"question":"What compliance documentation does Microchip Technology provide for 2N2222AL?","answer":"Microchip Technology typically provides compliance data sheets upon request — confirm the required documentation at the time of ordering."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/2N2222AL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/2N2222AL when reusing this data.
