IC Role / Device Role: Bidirectional protection not required - unidirectional configuration simplifies layout and reduces capacitance vs. bidirectional alternatives. Use Value: 1.0 mm height fits behind compact connectors; AEC-Q101 qualification eliminates need for additional qualification testing in Tier 1 BOMs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | DO-214AC (SMA) package; 30 V VBR (min/max 26.7–33.3 V); 300 W PPPM; 1.9 mm height | Lower surge rating and taller profile limit use in space-constrained automotive modules | Select when legacy SMA footprint compatibility is required and 400 W rating is not mandatory |
| TPSMD30A | DO-218AB (SMF) package; same VBR range; 400 W PPPM; 2.3 mm height; higher thermal mass | Greater board area usage and slower thermal response than SMP; suited for less thermally aggressive zones | Prefer when higher IFSM (100 A) and long-term power handling (5 W) outweigh low-profile needs |

FAQ
What is the clamping voltage of TPSMP30AHM3/84A at its rated peak pulse current?
The TPSMP30AHM3/84A has a maximum clamping voltage (VC) of 41.4 V at 9.7 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 and ensures downstream circuitry remains within safe operating limits during standardized surge events. The TPSMP30AHM3/84A achieves this with low incremental surge resistance inherent to its passivated anisotropic rectifier structure.
Is TPSMP30AHM3/84A suitable for automotive applications?
Yes, the TPSMP30AHM3/84A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications including engine control units, body control modules, and ADAS sensor interfaces. Its DO-220AA package meets MSL Level 1, and its ±5 % VBR tolerance (denoted by "A") ensures consistent clamping behavior across production lots. The TPSMP30AHM3/84A is explicitly listed in Vishay's automotive-grade product documentation.
What does the "HM3/84A" suffix indicate in TPSMP30AHM3/84A?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with matte tin-plated leads and JESD 201 Class 2 whisker resistance. The "/84A" indicates packaging in 7-inch plastic tape-and-reel format with 3000 units per reel. This ordering code aligns with Vishay's standard delivery mode for high-volume SMT assembly. The TPSMP30AHM3/84A uses the same die and qualification as other HM3-suffix variants in the TPSMP30A family.
How does TPSMP30AHM3/84A compare to bidirectional TVS diodes in signal line protection?
The TPSMP30AHM3/84A is unidirectional and optimized for DC-biased lines such as power rails or grounded-signal interfaces - offering lower leakage (<1.0 µA at 25.6 V) and tighter VBR tolerance than comparable bidirectional devices. It is not intended for AC-coupled or floating differential lines. For applications requiring symmetric clamping (e.g., RS-485), a bidirectional variant like TPSMP30AHM3/84A's counterpart would be necessary - but the TPSMP30AHM3/84A excels where unidirectional protection suffices with superior thermal and surge performance.
What is the recommended PCB pad layout for TPSMP30AHM3/84A?
Vishay specifies a 5.0 mm × 5.0 mm copper pad for each terminal to meet the thermal and surge test conditions used to rate the TPSMP30AHM3/84A at 400 W. These pads must be connected to internal ground/power planes via multiple thermal vias. The DO-220AA outline requires 2.67 mm × 1.27 mm land pattern with 0.105 inch (2.67 mm) overall length. Proper pad design ensures the TPSMP30AHM3/84A achieves its full rated power dissipation and avoids premature failure during repetitive surge events.
