MJD44H11T4G

MJD44H11T4G is an onsemi NPN power transistor in DPAK (case 369C), supplied on a 2,500-piece tape and reel, lead-free — for linear power stages, relay and solenoid driving and general-purpose amplification at real current. The ratings are the selection point: 80 V collector-emitter voltage and 8 A collector current, with saturation voltage of 1.0 V maximum at IC = 8 A and IB = 400 mA, and hFE of 40 minimum at IC = 4 A, VCE = 1 V — gain specified at amperes, not milliamperes, which is what separates a power transistor table from a small-signal one. One ordering caution that the maker's own tables settle: in the current revision the T4G code sits in the main ordering table while the T5G row sits in the discontinued section (which also lists two NJV-prefixed codes) — so the T4G must not inherit the T5G's mark, and this page makes no current-status claim beyond that table placement. Selection advice: at 8 A the DPAK copper area is the heatsink — budget board copper and check saturation dissipation at your duty cycle before committing the footprint. onsemi status wording for this code was not captured for this record, so no status is claimed here — the offered lot is confirmed against your requirement before quotation. Parameters verified against the onsemi MJD44H11 datasheet ordering and electrical tables.
