DESCRIPTION
APPEARANCE
This Microsemi Powermite
surface mount low noise Zener package series
provides a higher power handling capability that are also RoHS compliant.
In addition to its size advantages, Powermite
package features include a
full-metallic bottom that eliminates the possibility of solder flux entrapment
during assembly, and a unique locking tab acts as an efficient heat path
from die to mounting plane for external heat sinking with very low thermal
resistance junction to case (bottom).
Its innovative design makes this
device ideal for use with automatic insertion equipment.
DO-216

FEATURES
APPLICATIONS / BENEFITS
Surface mount equivalent to JEDEC registered
1N4099 thru 1N4135 and 1N4614 thru 1N4627
series except with additional power capability
RoHS compliant
Options for screening in accordance with Mil-PRF-
19500/435 for JAN, JANTX, JANTXV and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers. For example,
designate MX1PMT4099 for a JANTX (consult factory
for Tin-Lead plating if required).
Optional 100% avionics screening available by
adding MA prefix for 100% temperature cycle,
thermal impedance, and 24 hour HTRB testing
(consult factory for Tin-Lead plating if required).
Extensive selection from 1.8 to 100 V
Regulates voltage over a broad operating current
and temperature range
Low noise density (1-3 kHz) at test current
Low reverse leakage current
Tight tolerances available in plus or minus 2% or 1%
with C or D suffix respectively
Hermetically sealed surface mount package
Nonsensitive to ESD per MIL-STD-750 Method 1020
Compatible with automatic insertion equipment
Full metallic bottom eliminates flux entrapment
