* Pulse Test: Pulse Width

≤300µs, Duty Cycle≤2%

Ordering Information

* 1. Affix “-S-” means the standard TO126 Package.(see package dimensions). If the affix is ”-STS-” instead of “-S-”, that mean the short-lead TO126 package.

2. Suffix “-TU” means the tube packing, The Suffix “TU” could be replaced to other suffix character as packing method.
