STMicroelectronics SMA6J33
SMA6J33 variants from STMicroelectronics
SMA6J33 Overview
What changes between part numbers, and what to check before you lock the BOM — TVS Diodes.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: A-TR, CA-TR. 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 Variants
Compare 2 SMA6J33 part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| SMA6J33A-TR | 600W TVS Diode, 33V, Unidirectional, SMA, 60.8V Clamp | STMicroelectronics | Active | Compliant | In Stock | |
| SMA6J33CA-TR | 600W Bidirectional TVS Diode, 33V, SMA, 57A Peak Pulse Current | STMicroelectronics | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on SMA6J33 map to package, grade, and reel options.
How to Choose the Right SMA6J33 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 SMA6J33, 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 "SMA6J33" — include the full suffix (e.g. A-TR, CA-TR). RFQ with reel/tube preference and required date code.
