This specification covers the detail requirements for microminiature 1.5 watt silicon, low leakage, voltage regulator diodes with tolerances of 5 percent, 2 percent, and 1 percent. Four levels of product assurance are provided for each device type as specified in MIL-S-19500, and two level of product assurance for die.

See figures 1 (similar to DO-41), 2, and 3.

Maximum ratings are as shown in columns 8 and 10 of table III herein and as follows:
PT = 1.5 W (derate at 10 mW/°C above TA = +25°C) −55°C < Top < +175°C; −65°C < TSTG < +175°C




Primary electrical characteristics are as shown in columns 2, 9, 12, and 14 of table III herein and as follows:

3.3 V dc ≤ Vz ≤ 200 V dc

1N4460D through 1N4496D and 1N6485D through 1N6491D are 1 percent voltage tolerance.

1N4460C through 1N4496C and 1N6485C through 1N6491C are 2 percent voltage tolerance.

1N4460 through 1N4496 and 1N6485 through 1N6491 are 5 percent voltage tolerance.
RΘJL = 42°C/W (max) at L = .375 inch (9.52 mm) (nonsurface mount)


RΘJEC = 20°C/W (max) (surface mount)
