H* = H2, H4 or H6 for A or C pinning options with 2kVDC, 4kVDC or 6kVDC isolation.
H* = H for B pinning option with 1.6kVDC isolation only.
Besides the standard isolation of 2kVDC, this series offers options of 4kVDC (= "/HH44") or 6kVDC (= "/HH66") makingit
suitable for medical applications and other sophisticated industrial applications. Packaging can be either DIP-24 plastic
or 5-side-shielded DIP24 metal case (= option "/MM") as well as SMD pinning (= option "/SSMMDD"). For all the above
variants, 2 industry-standard pinouts (= option "/AA"or "/CC") are available, and B pinning is available with 1.6kVDC
isolation. Remote on/off control is possible with the //CCTTRRLLoption (A pinning only)

* add suffix "/AA", “/BB”or "/CC" for pinning options,
see next page and Isolation Restrictions.
* add suffix "/MM" for metal case.
* add suffix "/SSMMDD" for SMD package.
* add suffix “//CCTTRRLL” for control pin option
(A Pinning only)
Isolation Restrictions
‘B” Pinning is restricted to 1.6kV isolation due
to the closeness of the input and output pins.
If the options "/MM" for metal case and "/SSMMDD"
for SMD pinout are combined, the maximum
allowed isolation voltage is 2kVDC because of
the shorter distances between pins and the
metal case.
DIP-24 through-hole case and SMD-plastic
case are not affected and offer the full isolation
barriers of 2kV through to 6kVDC.
