1N5913BUR-1 thru 1N5956BUR-1

(or MLL5913B thru MLL5956B)

METALLURGICALLY BONDED GLASS

SURFACE MOUNT 1.5 WATT ZENERS

S C O T T S D A L E D I V I S I O N

DESCRIPTION

APPEARANCE

This surface mountable 1.5 W Zener diode series in the JEDEC DO-213AB

package is similar in electrical features to the JEDEC registered 1N5913B

thru 1N5956B axial-leaded package for 3.3 to 200 V. It is an ideal selection

for applications of high density and low parasitic requirements. Due to its

glass hermetic qualities and metallurgically enhanced internal contacts, it

may also be used for high reliability applications when required by a source

control drawing (SCD) or screening in accordance with MIL-PRF-19500 as

described in Features below. Zener voltage tolerance options are identified

by part number suffix including tight-tolerance. A variety of other Zener

product offerings and packages are available by Microsemi to meet higher

DO-213AB

or lower power and test current applications.

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

FEATURES

APPLICATIONS / BENEFITS

•

Electrically similar to the JEDEC registered 1N5913B

• Regulates voltage over a broad operating current

thru 1N5956B zener series

and temperature range

•

Zener voltages available 3.3V to 200V

• Wide selection from 3.3 to 200 V

• Leadless package for surface mounting

• Ideal for high density mounting

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, e.g. MX1N5913BUR-1,

MV1N5923CUR-1, MSP1N5952DUR-1, etc.

Surface mount equivalents also available as

SMBJ5913B to SMBJ5956B, SMBG5913B to

SMBG5956B, SMAJ5913B to SMAJ5956B, or as

1PMT5913B to 1PMT5956B (see separate data

sheets)

• Metallurgically enhanced internal contact design for

greater reliability and lower thermal resistance

•

Standard voltage tolerances are +/- 5% with B suffix

•

and 10 % with A suffix identification

Tight tolerances available in plus or minus 2% or

1% with C or D suffix respectively

• Nonsensitive to ESD

• Hermetically sealed glass package

• Specified capacitance (see Figure 2)

Plastic body axial-leaded Zener equivalents are also

available as 1N5913BP to 1N5956BP (see separate

data sheet)

• Inherently radiation hard as described in Microsemi

MicroNote 050

MAXIMUM RATINGS

MECHANICAL AND PACKAGING

•

Power dissipation at 25^ºC: 1.5 watts (also see

derating in Figure 1).

• CASE: Hermetically sealed DO-213AB glass MELF

package

•

Operating and Storage temperature: -65^ºC to +175^ºC

• TERMINALS: End caps, tin-lead plated solderable

Thermal Resistance: 40 ^ºC/W junction to end cap, or

120^ºC/W junction to ambient when mounted on FR4

PC board (1 oz Cu) with recommended footprint (see

last page)

per MIL-STD-750, method 2026

• POLARITY: Cathode indicated by band. Diode to

be operated with the banded end positive with

respect to the opposite end for Zener regulation

•

Steady-State Power: 1.50 watts at T_EC< 115^oC, or

1.25 watts at T_A= 25^ºC when mounted on FR4 PC

board and recommended footprint as described for

thermal resistance (also see Figure 1)

• MARKING: Cathode band only

• TAPE & REEL optional: Standard per EIA-481-B

with 12 mm tape, 1500 per 7 inch reel or 5000 per

13 inch reel (add “TR” suffix to part number)

• WEIGHT: 0.05 grams

• See package dimensions on last page

•

Forward voltage @200 mA: 1.2 volts (maximum)

Solder Temperatures: 260 ^ºC for 10 s (max)
