  • Operating temperature range (T J) is -40 °C to +125 °C.
  • Storage temperature range (T S) is -40 °C to +125 °C.
  • Lead solder temperature is a maximum of 230 °C for 10 seconds maximum at a minimum of 1/16" (1.59 mm) from case.
  • The case temperature (T C) is measured as shown on dimensional outline drawings in the “Package Dimensions” section of this catalog.
  • Teccor's electrically-isolated TO-220 devices withstand a high potential test of 2500 V ac rms from leads to mounting tab over the operating temperature range.
  • Typical Reverse Recovery Time (t rr) is 4 µs. (Test conditions = 0.9 A forward current and 1.5 A reverse current.) Electrical Specification Notes (1) See Figure E7.3 for current rating at specified case temperature. (2) For more than one full cycle rating, see Figure E7.4. (3) T C = TJ for test conditions (4) See package outlines for lead form configurations. When ordering special lead forming, add type number as suffix to part number.
