PCN Information:
Description of Change:Littelfuse IXYS Integrated Circuits Division (ICD) would like to inform you that we have qualified an additional material for use in back-side metallization process, for the part numbers listed in this PCN.*Effective date: December 30, 2025
Description and Reason for Change:Littelfuse IXYS Integrated Circuits Division (ICD) would like to inform you about the qualification of an additional EMC (Epoxy Mold Compound) to ensure security of supply
Description of ChangeLittelfuse IXYS Integrated Circuits Division (ICD) would like to inform you of a change to the data sheet parameter “Input Control Current to Deactivate”, with the addition of an “Input Control Voltage to Deactivate” parameter.Reason for ChangeTo ensure the security of supply for these products, an alternative supplier of the input LED was qualified and put into production. This more efficient LED can maintain the activated state of the Solid State Relays (SSRs) at lower input currents than its predecessor. Reducing the minimum input control current to 0.1 mA guarantees the SSRs will deactivate as expected.
Detailed Description of ChangeLittelfuse IXYS Integrated Circuits Division (ICD) would like to inform you of a change to the data sheet parameter “Input Control Current to Deactivate”, with the addition of an “Input Control Voltage to Deactivate” parameter and the Moisture Sensitivity Level (MSL) classification change from MSL1 to MSL3. The minimum “Input Control Current to Deactivate” rating is being reduced from 0.4 mA to 0.1 mA. A new parameter, “Input Control Voltage to Deactivate”, is being added to the data sheet with a minimum rating of 0.8 V.Reason for ChangeTo ensure the security of supply for these products, an alternative supplier of the input LED was qualified and put into production. This more efficient LED can maintain the activated state of the Solid State Relays (SSRs) at lower input currents than its predecessor. Reducing the minimum input control current to 0.1 mA guarantees the SSRs will deactivate as expected. In order to simplify circuit design where the input current cannot be accurately predicted, a secondary deactivation input control parameter is being provided. This supplementary deactivation parameter is based on the voltage applied to the input LED. As stated in the updated data sheets, the minimum voltage applied to the input LED that will sustain operation is 0.8 V. The Moisture Sensitivity Level (MSL) classification of the PBA150 is being temporarily changed from MSL1 to MSL3. This change is a containment action implemented to prevent a potential issue with mechanical stress on bond wires, which may be exacerbated by residual moisture in a minor percentage of PBA150 devices. MSL3 rating will be maintained until further notice from Littelfuse. These changes are effective immediately and will be documented in the updated data sheet on the Littelfuse website.
