Yageo KEMET 1.5SMC440
1.5SMC440 variants from Yageo KEMET
1.5SMC440 Overview
What changes between part numbers, and what to check before you lock the BOM — TVS Diodes.
1.5SMC440 is a Yageo KEMET order-code family — not a single orderable MPN. This page lists 2 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
1.5SMC, DO-214AB, 376V, 602V, RE Other listed variants describe: Trans Voltage Suppressor Diode,.
Suffix examples in this family: A/TR13, CA/TR13. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: 1.5SMC440A/TR13, 1.5SMC440CA/TR13.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: A/TR13, CA/TR13. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- TVS Diodes — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

Ordering Code Differences
How suffixes on 1.5SMC440 map to package, grade, and reel options.
1.5SMC440 uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: A/TR13, CA/TR13.
Full MPN examples: 1.5SMC440A/TR13, 1.5SMC440CA/TR13.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right 1.5SMC440 TVS Diodes
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For 1.5SMC440, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "1.5SMC440" — include the full suffix (e.g. A/TR13, CA/TR13). RFQ with reel/tube preference and required date code.
