Product details

The TTC004B,Q is a 160 V, 1.5 A NPN bipolar transistor in a TO-126N through-hole package, rated for 10 W continuous power dissipation at a junction temperature up to 150 °C. Vce saturation is specified at 500 mV max at a forced-beta condition of 50 mA base drive into 500 mA collector current, which gives a reasonable guide for saturated-switch designs at moderate current.

The TO-126N (also listed as TO-225AA / TO-126-3) is a three-lead through-hole package with a metal tab for heatsinking — the tab is internally connected to the collector, so the PCB copper or an external heatsink must account for that electrical potential. Mounting is through-hole, so the lead pitch and hole pattern match the standard TO-126 footprint; the Bulk packaging means it ships as individual units, not on tape and reel.

Lifecycle and compliance

The collector cutoff current (ICBO) is specified at 100 nA maximum, which is a standard figure for a silicon transistor of this voltage class and indicates a clean junction.

Frequently asked questions

What is the closest functional complement to TTC004B,Q?

The TTA004B,Q is the PNP complement — same 10 W power rating, same 100 MHz fT, same 160 V Vce and 1.5 A Ic ratings, but PNP polarity. It shares the same TO-126N package and through-hole mounting, so a push-pull or complementary output stage can use the same heatsink layout and PCB footprint for both halves.
