Notes
(1) IO1 is rated at 1.75A @ TA = 25°C for PC boards where thermal resistance from mounting point to ambient is sufficiently controlled where
TJ(Max) does not exceed 175°C; This equates to R
θJA(PCB)
≤
85°C/W.
(2) TA = 25°C @ IO=0A and VRWM = 0V for ten 8.3mS surges at 1 minute intervals.
(3) PCB = FR4, 0.0625 Inch (1.59mm) thick, single layer, 1.0-Oz Cu, Pad Size, (1.0” x 1.0”), (645mm x 645mm) , horizontal in still air.
(4) PCB = FR4, 0.0625 Inch (1.59mm) thick, single layer, 1.0-Oz Cu, Pad Size, (0.070” x 0.155”)‡, (1.78mm x 3.94mm) ‡, horizontal in still air.
IO1 is rated at 1.5A @ TA = 25°C for PC boards where R
θJA(PCB)
≤
111°C/W. Derate at 10mA/°C above TA = 25°C in this case.

* The additional contact provides a connection to the lid in the application. Connecting the metal lid to a known electrical potential stops deep
dielectric discharge in space applications; see the Space Weather link

on the Semelab web site. Package variant
to be specified at order.
†
The DLCC3 package design takes full advantage of the proven high reliability pedigree of the HTCC surface mount packaging technology,
which is easily integrated for automated assembly. Semelab has taken the existing standards for ceramic surface mount package manufacture
and added additional design features to enhance thermal performance, to present a competitive alternative for high reliability applications.

Soldering temperature should be 260°C for a
maximum of 10 seconds.
The physical dimensions for the DLCC3 ceramic package are designed
to be different from the published dimensions for the “D-5B” and “E-
MELF” outlines. The DLCC3 design fully utilises the recommended
solder footprint for the “D-5B” / “E-MELF” Package, and as such
presents a drop in replacement for existing board designs.

SCREENING OPTIONS
Space Level (JQRS/ESA) and High Reliability options are
available in accordance with the
High Reliability and
Screening Options Handbook
available for download from
the from the TT electronics Semelab web site.
ESA Quality Level Products are based on the testing
procedures specified in the generic ESCC 5000 and in the
corresponding part detail specifications.
Semelab’s QR216 and QR217 processing specifications
(JQRS), in conjunction with the companies ISO 9001:2000
approval present a viable alternative to the American MIL-
PRF-19500 space level processing.
QR217 (Space Level Quality Conformance) is based on the
quality conformance inspection requirements of MIL-PRF-
19500 groups A (table V), B (table VIa), C (table VII) and
also ESA / ESCC 5000 (chart F4) lot validation tests.
QR216 (Space Level Screening) is based on the screening
requirements of MIL-PRF-19500 (table IV) and also ESA
/ESCC 5000 (chart F3).
JQRS parts are processed to the device data sheet and
screened to QR216 with conformance testing to Q217
groups A and B in accordance with MIL-STD-750 methods
and procedures.
Additional conformance options are available, for example
Pre-Cap Visual Inspection, Buy-Off Visit or Data Packs.
These are chargeable and must be specified at the order
stage (See Ordering Information). Minimum order
quantities may apply.
Alternative or additional customer specific conformance or
screening requirements would be considered. Contact
Semelab sales with enquires.

samples must be ordered
3) All destructive samples are marked the same as other production parts unless
otherwise requested.
MARKING DETAILS
Parts can be laser marked with approximately 7 characters
on two lines and always includes cathode identification.
Typical marking would include part or specification number,
week of seal or serial number subject to available space and
legibility.
Customer specific marking requirements can be arranged at
the time of order.
Example Marking:
Example ordering information:
The following example is for the 1N6626D3A / 1N6626D3B
part with package variant A, JQRS screening, additional
Group C conformance testing and a Data pack.
