Product details
Overview
TPSMP27HE3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for automotive-grade overvoltage protection of signal lines and ICs. It features a 24.3 V to 29.7 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 µs), 10.2 A peak pulse current (IPPM), and clamps to 39.1 V at rated surge, meeting AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the TPSMP27HE3/84A datasheet, TPSMP27HE3/84A pinout, TPSMP27HE3/84A application, or TPSMP27HE3/84A equivalent, key selection criteria include its 1.0 mm profile, low incremental surge resistance, RoHS-compliant matte tin terminals, and validated performance under 150 °C junction temperature with <1 µA leakage at 21.8 V stand-off voltage.
Technical Context
The TPSMP27HE3/84A employs Vishay's patented PAR oxide-passivated chip construction to achieve stable breakdown characteristics and excellent clamping response. Its unidirectional configuration enables precise anode-to-cathode surge shunting with fast response time (<1 ns) and low dynamic impedance during transient events.
Rated for 185 °C maximum junction temperature and MSL Level 1 reflow compatibility (260 °C peak), it delivers 2.5 W steady-state power dissipation on infinite heatsink and withstands 40 A non-repetitive forward surge current (10 ms half-sine), supporting robust protection in automotive sensor interfaces and power supply rails.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28A-E3/5AT | Higher VBR (25.2–27.8 V), lower PPPM (400 W same), but SMA package (2.2 mm height) and no AEC-Q101 qualification | Not suitable for automotive under-hood use; acceptable for industrial/commercial board-level protection where height and qualification are not critical | Select TPSMP27HE3/84A when AEC-Q101 compliance, 1.0 mm profile, or MSL Level 1 reflow are required |
| TPSMP27AHE3/84A | Narrower VBR range (25.7–28.4 V), tighter 5 % tolerance vs. TPSMP27HE3/84A's 10 %, identical package and ratings | Preferred for precision-clamp applications where tighter breakdown consistency improves margin against overvoltage failure | Choose TPSMP27HE3/84A for cost-sensitive volume production where ±10 % VBR meets design margin; select TPSMP27AHE3/84A for tighter tolerance needs |
Compared with SMAJ28A-E3/5AT, the TPSMP27HE3/84A offers automotive qualification and half the height; versus TPSMP27AHE3/84A, it trades tighter VBR tolerance for broader manufacturing yield and lower unit cost-both alternatives retain DO-220AA footprint but differ in qualification scope and parametric tightness.

FAQ
What is the breakdown voltage range of the TPSMP27HE3/84A?
The TPSMP27HE3/84A has a specified breakdown voltage (VBR) range of 24.3 V minimum to 29.7 V maximum at 1 mA test current. This 10 % tolerance band ensures reliable triggering above typical 24 V nominal system voltages while accommodating process variation, and is verified per ANSI/IEEE C62.35 standards in the Vishay datasheet Document Number 88471.
Is the TPSMP27HE3/84A qualified for automotive use?
Yes, the TPSMP27HE3/84A is AEC-Q101 qualified and designated as high-reliability/automotive grade (suffix "A" in base P/NHE3). It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance per AEC-Q101 Rev D, making it suitable for engine control units, body electronics, and ADAS modules where automotive-grade reliability is mandatory.
What does the "HE3/84A" suffix mean in TPSMP27HE3/84A?
The "HE3" suffix indicates RoHS-compliant, high-reliability construction with matte tin-plated leads and JESD201 Class 2 whisker resistance; "84A" specifies the preferred packaging: 3000-piece 7-inch plastic tape-and-reel delivery mode. This ordering code aligns with Vishay's standard nomenclature in Document Number 88471 and ensures correct reel orientation and moisture sensitivity handling.
How does the TPSMP27HE3/84A compare to the TPSMP27AHE3/84A variant?
The TPSMP27HE3/84A has a wider VBR range (24.3–29.7 V) than the TPSMP27AHE3/84A (25.7–28.4 V), reflecting a ±10 % vs. ±5 % tolerance. Both share identical DO-220AA package, 400 W PPPM rating, AEC-Q101 qualification, and thermal specs; the "A" variant offers tighter parametric control for designs requiring stricter clamping consistency.
What is the maximum clamping voltage of the TPSMP27HE3/84A at rated surge current?
The TPSMP27HE3/84A clamps to a maximum of 39.1 V at its rated peak pulse current (IPPM) of 10.2 A under 10/1000 µs waveform conditions. This value is measured per Figure 1 and Table on page 2 of Vishay Document Number 88471 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
