ECCN:
PCN Information:
Description:To further strengthen the security and continuity of supply for our customers, Littelfuse will be adding a new assembly and test site for Axial Leaded DO-41 DO-15 and DO-201 packages. The electrical performance of the affected Series will remain within existing datasheet specifications. There will be no change to the fit, form, and function of the products. Implementation Date for Change: July 23, 2025
In order to support our fast-growing demand and secure continuity of supply for our customers, the TVS STD products listed will now be built on 6-inch wafers in addition to 5-inch wafers. The 6-inch wafers will be processed using new 6-inch capable furnaces and equipment, with optimized 6-inch wafer process steps.Effective date: Aug 1st, 2023
TVS STD Axial Leaded packages additional Epoxy Molding Compound approval.Effective 18 April 2023, Littelfuse will be adding a new epoxy molding compound (EMC) for our Axial Leaded packages commercial TVS products. This urgent addition is necessary due to circumstances beyond Littelfuse, as the current supplier recently obsoleted the EMC used by the Affected Series. There will be no change to the datasheet specifications for the Affected Series. There will be no change to the form, fit, function, or reliability of the products.

Features & Applications
The 1.5KE43A is a Transil diode provides high overvoltage protection by clamping action. Their instantaneous response to transient over voltages makes them particularly suited to protect voltage sensitive devices such as MOS Technology and low voltage supplied IC’s.
Features:
- Peak pulse power: 1500 W (10/1000 µs)
- Breakdown voltage range: From 6.8 V to 440 V
- Uni and bidirectional types
- Low clamping factor
- Fast response time
- UL 497B file number: QVGQ2.E136224
