THAT Offers Transistor Array in Die Form |

Milford , MA - The new THAT 380G, a transistor array consisting of four PNP and four NPN transistors on a single substrate, is now available from THAT Corporation. The array is manufactured in THAT’s proprietary dielectric isolation (DI) process, with each transistor electrically isolated in its own insulating tub. The result is extremely low collector-to-substrate capacitance, giving the 380G transistors fT’s of 350 MHz (NPN) and 325 MHz (PNP) and ensuring inter-device DC isolation approaching that of physically separate devices. Latch-up free operation is also assured since no substrate currents are allowed to flow to the individual transistors. The devices exhibit low noise -- 0.75 nV/root-Hz for the PNP, 0.80 nV/root-Hz for the NPN -- and excellent VBE matching (typically ±500 µV) between pairs of devices of the same polarity. And because the 380G transistors don’t rely on reverse-biased PN junctions for electrical isolation, they continue to operate at much higher temperatures than conventional junction-isolated devices. Inter-device breakdown voltages are in the hundreds of volts. The THAT 380G, available only in die form, is suitable for use in multi-chip modules, hybrids, and chip-on-board applications, and is priced at $4.90 in thousand-piece quantities.
