DESCRIPTION APPEARANCE

This “Ultrafast Recovery” rectifier diode series is military qualified to MIL-PRF-

19500/585 and is ideal for high-reliability applications where a failure cannot be

tolerated. These industry-recognized 1.5 to 2.0 Amp rated rectifiers for working

peak reverse voltages from 200 to 1000 volts are hermetically sealed with voidless-

glass construction using an internal “Category I” metallurgical bond. These devices

are also available in axial-leaded packages for thru-hole mounting (see separate

data sheet for 1N6620 thru 1N6625). Microsemi also offers numerous other rectifier

products to meet higher and lower current ratings with various recovery time speed

requirements including standard, fast and ultrafast device types in both through-hole

and surface mount packages.

Package “A”

or D-5A

MicroNote 050

MAXIMUM RAT ING S MECHANICAL AND PACKAGING

• Junction Temperature: -65oC to +175oC

• Storage Temperature: -65oC to +175oC

• Peak Forward Surge Current @ 25oC: 20 Amps (except

1N6625 which is 15 Amps)

Note: Test pulse = 8.3 ms, half-sine wave.

• Average Rectified Forward Current (IO) at TEC=+110oC:

1N6620 thru 1N6622: 2.0 Amps

1N6623 thru 1N6625: 1.5 Amps

(Derate linearly at 1.5%/oC for TEC > +110oC)

• Average Rectified Forward Current (IO) at TA=25oC:

1N6620 thru 1N6622: 1.2 Amps

1N6623 thru 1N6625: 1.0 Amp

(Derate linearly at 0.67%/ oC for TA>+25oC. This IO

rating is typical for PC boards where thermal resistance

from mounting point to ambient is sufficiently controlled

where TJ(max) is not exceeded.)

• Thermal Resistance junction to endcap (RθJEC): 20oC/W

• Capacitance at VR= 10 V: 10 pF

• Solder temperature: 260oC for 10 s (maximum)

• CASE: Hermetically sealed voidless hard glass

with Tungsten slugs

• TERMINATIONS: End caps are Copper with

Tin/Lead (Sn/Pb) finish. Note: Previous inventory

had solid Silver end caps with Tin/Lead plating.

• MARKING: Cathode band only

• POLARITY: Cathode indicated by band

• Tape & Reel option: Standard per EIA-481-B

• Weight: 193 mg

• See package dimensions and recommended pad

SYMBOLS & DEFINITI ONS

Symbol Definition

VBR Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current.

VRWM Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating

temperature range.

VF Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
