Microsemi 1N5985, 1N6031-1 Technical data

查询1N6022A供应商

SCOTTSDALE DIVISION

The popular 1N5985 thru 1N6031 series of 0.5 watt Zener Voltage Regulators
provides a selection from 2.4 to 200 volts in standard 5% or 10% tolerances as
well as tighter tolerances identified by different suffix letters on the part number.
These glass axial-leaded DO-35 Zeners are also available in various military
screening levels by adding a prefix identifier as described in the Features
section. Microsemi also offers numerous other Zener products to meet higher
and lower power applications.

IMPORTANT: For the most current data, consult

• JEDEC registered 1N5985 to 1N6031

• Similar to operating current conditions of the BZX55

Pro Electron series of Zener products in Europe

• Internal bonds optionally available with “-1” suffix

• Options for screening in accordance with MIL-PRF-

19500 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers with “-1” suffix.

• Surface mount equivalents available as MLL5985 to
MLL6031 in the DO-213AA MELF style package
including “-1” suffix options (consult factory for others)

• DO-7 glass body axial-leaded Zener equivalents are
also available

• Power dissipation at 25
in Figure 1).

• Operating and Storage temperature: -65

• Thermal Resistance: 250

(10 mm) lead length from body, or 310
ambient when mounted on FR4 PC board (1 oz Cu)
with 4 mm2 copper pads and track width 1 mm, length
25 mm

• Steady-State Power: 0.5 watts at T
(10 mm) from body or 0.48 W at T
mounted on FR4 PC board as described for thermal
resistance above (also see Figure1)

• Forward voltage @200 mA: 1.1 volts (maximum)

• Solder Temperatures: 260

1. Zener Impedance is derived from the 1 kHz ac voltage which results when an ac current having an rms value equal to 10% of
dc zener current (I

or IZK) is superimposed on IZT or IZK. See MicroNote 202 for dynamic impedance variation with other

ZT

operating currents.

2. Voltage Measurements to be performed 20 seconds after application of the dc test current.

3. The maximum zener current I
