Given that D1 in your project is an SMBJ5.0A, which is a transient voltage suppressor (TVS) diode from Littelfuse Inc. designed to protect electronic equipment against voltage spikes, I recommend the following replacement based on the project needs:
Recommended Replacement: 1.5KE5.0A
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")
Manufacturer Name: STMicroelectronics or a preferred alternative
Designator Prefix: D
Why 1.5KE5.0A?
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.
Things to Consider:
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.
Please verify these parameters suit your project's specific needs before making a final decision. If your space or thermal management setups are constrained, you might need to consider alternatives or adjustments in your design.
