LRC
Functional alternative with matching voltage and higher power (500mW), but in a larger package (SOD-123).
Find and compare replacements for the PDZ24B_R1_00001, a 24V 400mW Zener diode in a SOD-323 package. Review functional alternatives and parametric downgrades.
Most alternatives are in different packages, requiring a PCB redesign.
The only package-compatible option has a 50% lower power rating.
No direct, risk-free drop-in replacement was found. The closest package match, LM3Z24VT1G, has a significant power downgrade.
Functional alternatives with higher power ratings (e.g., LBZT52C24T1G) are available but require a board spin due to different packages.
The primary risks are either mechanical incompatibility (package mismatch) or electrical overstress (power downgrade).

| Feature / factor | PDZ24B_R1_00001 | LBZT52C24T1G | ZMM24 | LM3Z24VT1G | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOD-323 | SOD-123 | LL-34 | SOD-323 | SOD-123 / LL-34 / SOD-323 — Larger package requires PCB layout change.; ZMM24: Different package requires PCB layout change.; LM3Z24VT1G: Package is a direct match. |
| Voltage | 24.0 V | 24.0 V | 24.0 V | 24.2 V | 24.0 V / 24.2 V — Nominal voltage matches target.; ZMM24: Nominal voltage matches target.; LM3Z24VT1G: Nominal voltage is very close, likely within tolerance. |
| Power | 400 mW | 500 mW | 500 mW | 200 mW | 500 mW / 200 mW — Higher power rating provides more margin.; ZMM24: Higher power rating provides more margin.; LM3Z24VT1G: Power rating is 50% lower than target. |
| Impedance | 30 Ohm | - | - | 70 Ohm | 70 Ohm — Higher impedance may affect regulation performance. |
No direct drop-in replacement has been identified. Functional alternatives like LBZT52C24T1G offer higher power but require a PCB layout change due to a different package.
