• Manufacturer: STMicroelectronics or similar
• MPN: 1.5KE5.0A
• Description: This is also a transient voltage suppressor diode, designed to handle 1500 W peak pulse power dissipation for reliable transient voltage protection. It has a standoff voltage of 5.0 V, similar to the SMBJ5.0A, ensuring compatibility with your existing design.
• Pins: 2 (1 - Cathode, named "K"; 2 - Anode, named "A")
• Element Properties:
  • License: https://creativecommons.org/licenses/by/4.0/
  • Manufacturer Name: STMicroelectronics or a preferred alternative
  • Designator Prefix: D

• Power Dissipation: It can handle higher power spikes compared to SMBJ series, offering additional robustness to your design.
• Package Type: The 1.5KE series usually come in a DO-201 package which is bigger than the SMB package of the SMBJ5.0A, thus easier to handle in terms of soldering and physical inspection.
• Compatibility: With a similar working peak reverse voltage (5.0V), it ensures that the protection level remains consistent with the requirements of your Raspberry Pi PSU interface.

• Board Space: Given the larger package size (DO-201), ensure your PCB layout has enough space for this replacement.
• Mounting and Heat Dissipation: Verify whether the increased power dissipation capacity aligns with your thermal management strategy.
