International Rectifier Announces Production of TempSENSE HEXFET Power MOSFETs

May 07, 2000 by Jeff Shepard

International Rectifier (El Segundo, CA) have announced the production of their first TempSENSE HEXFET power MOSFET, which can provide cost-effective temperature sensing for automotive system protection by using an on-chip temperature sensing diode.

The IRLBD59N04E is a 40V, 20 mohms, N-channel MOSFET. Temperature sensing is provided by two anti-parallel, electrically isolated, poly-silicon diodes. The diode's forward voltage falls approximately 0.4V with a bias current of 250uA when the MOSFET reaches its maximum permitted temperature value.

The new device will meet the rigid Q101 automotive stress test qualification procedure at 175 degrees C when the devices are released into production in July 2000. The Q101 certification process is designed to ensure high-reliability component performance in harsh automotive environments. The 175-degree C temperature rating is necessary for engine compartment and other high-temperature applications. Thus, the IRLBD59N04E is well-suited for electric power-assist steering, anti-lock brakes and fuel-injection systems, as well as power door locks, window lifts and car audio circuits.

Samples are available immediately. Pricing is $0.80 in 10,000-unit quantities. Data sheets are available on the company's website with complete specifications.
