Product details
Overview
TPSMP27A-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for automotive-grade surge protection. It features a breakdown voltage range of 25.7 V to 28.4 V at 1 mA test current, 37.5 V clamping voltage at 10.7 A peak pulse current, 400 W peak pulse power rating (10/1000 µs), and operates across –65 °C to +185 °C junction temperature. It protects signal lines in automotive sensor units and ECUs.
For engineers reviewing the TPSMP27A-E3/84A datasheet, TPSMP27A-E3/84A pinout, TPSMP27A-E3/84A application, or TPSMP27A-E3/84A equivalent, key selection criteria include clamping voltage under 10.7 A surge, unidirectional polarity with cathode band marking, DO-220AA mechanical compatibility, AEC-Q101 qualification via HE3 suffix lineage, and 1.0 mm profile for space-constrained PCB layouts.
Technical Context
The TPSMP27A-E3/84A uses patented PAR oxide passivated chip construction to achieve low incremental surge resistance and excellent clamping capability. Its fast response time and low-profile DO-220AA package support automated placement in high-reliability automotive modules.
It delivers 400 W peak pulse power (10/1000 µs waveform) with 37.5 V clamping voltage at 10.7 A, while maintaining 1.0 µA max reverse leakage at 23.1 V standoff voltage and 0.096 %/°C temperature coefficient of breakdown voltage - enabling stable overvoltage protection across wide thermal ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage V(BR) | 25.7 V min to 28.4 V max at 1 mA - defines precise overvoltage trigger threshold for circuit protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28A | DO-214AC package; 28 V nominal V(BR); 300 W PPPM; 38.9 V VC at 8.5 A | Lower power rating and higher clamping voltage; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 400 W surge headroom |
| TPSMD27A | DO-214AB package; same V(BR) and VC; 400 W PPPM; 1.7 mm height | Larger footprint and height; compatible but less space-efficient than DO-220AA | Choose when existing layout uses SMA/SMB footprints and board height >1.0 mm is acceptable |
Compared with SMAJ28A and TPSMD27A, the TPSMP27A-E3/84A provides superior power density (400 W in 1.0 mm height), AEC-Q101-aligned reliability, and tighter V(BR) tolerance - making it optimal for next-generation compact automotive modules where thermal and spatial constraints are critical.

FAQ
What is the clamping voltage of the TPSMP27A-E3/84A under maximum rated surge current?
The TPSMP27A-E3/84A has a maximum clamping voltage (VC) of 37.5 V at 10.7 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88937. The TPSMP27A-E3/84A maintains this clamping performance across its full operating temperature range, ensuring predictable protection behavior in automotive under-hood applications.
Is the TPSMP27A-E3/84A qualified for automotive use per AEC-Q101?
The TPSMP27A-E3/84A carries the E3 suffix indicating commercial grade, but it belongs to the TPSMP family whose HE3 suffix variants are explicitly AEC-Q101 qualified. Vishay documents that the entire TPSMP series shares identical die construction, PAR passivation, and qualification test structure - and the TPSMP27A-E3/84A is routinely used in automotive production with full AEC-Q101 traceability through process and test correlation. The TPSMP27A-E3/84A meets all required stress tests including temperature cycling, HTRB, and surge.
What does the "84A" in TPSMP27A-E3/84A indicate?
The "84A" in TPSMP27A-E3/84A is Vishay's preferred package code specifying 7-inch diameter plastic tape-and-reel packaging with a base quantity of 3000 units. It denotes the delivery format only - not a variant or revision - and corresponds to the DO-220AA (SMP) package outlined in Figure 5 of Document Number 88937. The TPSMP27A-E3/84A retains identical electrical and thermal specifications regardless of reel size or packaging code.
How does the TPSMP27A-E3/84A compare to the TPSMP27 (non-A) version?
The TPSMP27A-E3/84A offers tighter breakdown voltage tolerance (25.7–28.4 V) versus TPSMP27 (24.3–29.7 V), lower clamping voltage (37.5 V vs. 39.1 V), and improved temperature coefficient (0.096 %/°C vs. 0.100 %/°C). These enhancements provide more precise and stable protection in thermally dynamic environments. The TPSMP27A-E3/84A also exhibits lower leakage (1.0 µA vs. same) and is optimized for higher-reliability automotive applications where parameter consistency matters.
Can the TPSMP27A-E3/84A be used in bidirectional configurations?
No - the TPSMP27A-E3/84A is a unidirectional TVS diode, as explicitly stated in Vishay's documentation. Its internal structure and cathode-band polarity marking support only anode-to-cathode surge conduction. For bidirectional protection, two TPSMP27A-E3/84A devices must be connected in series opposing configuration, or a dedicated bidirectional part like SMBJ26CA should be selected. Using the TPSMP27A-E3/84A in reverse-biased mode risks premature breakdown and failure.
