Product details
Overview
TPSMP20HE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) in DO-220AA (SMP) package, with 18.0 V to 22.0 V breakdown voltage (VBR), 13.7 A peak pulse current (IPPM), 29.1 V clamping voltage (VC) at IPPM, and AEC-Q101 qualification for under-hood electronics protection.
For engineers reviewing the TPSMP20HE3/84A datasheet, TPSMP20HE3/84A pinout, TPSMP20HE3/84A application, or TPSMP20HE3/84A equivalent, key selection criteria include unidirectional clamping performance, 1.0 mm profile for space-constrained PCB layouts, MSL Level 1 reflow compatibility, and automotive-grade reliability per JESD201 Class 2 whisker testing.
Technical Context
The TPSMP20HE3/84A employs patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and excellent clamping capability under 10/1000 µs transients. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining low leakage (<1.0 µA at VWM = 16.2 V).
Designed for surface-mount placement on FR-4 PCBs with 5.0 × 5.0 mm copper pads per terminal, it delivers 400 W peak pulse power (PPPM) at VBR ≥ 13 V, operates from −65 °C to +185 °C junction temperature, and meets RoHS 2002/95/EC and WEEE 2002/96/EC directives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 18.0 V min / 22.0 V max at 1.0 mA test current - defines precise overvoltage triggering threshold |
| Clamping Voltage VC | 29.1 V max at 13.7 A IPPM - limits downstream IC voltage stress during surge |
| Peak Pulse Power PPPM | 400 W (10/1000 µs waveform) - supports high-energy automotive load-dump immunity |
| Stand-off Voltage VWM | 16.2 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| Junction Temperature Range | −65 °C to +185 °C - enables operation in engine compartment and powertrain environments |
| Package | DO-220AA (SMP), 1.0 mm typical height - ultra-low profile for automated SMT assembly |
| AEC-Q101 Qualified | Yes - validated for automotive electronic units requiring high-reliability transient suppression |
Pinout & Package
DO-220AA (SMP) package: single-axis molded case with cathode band marking; matte tin-plated leads solderable per J-STD-002 and JESD22-B102; meets UL 94 V-0 flammability rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ20A | DO-214AC (SMA) package; 20 V VBR range; 400 W PPPM; no AEC-Q101 qualification | Limited to industrial/commercial use; lacks automotive reliability validation and JESD201 Class 2 whisker resistance | Select SMAJ20A only for non-automotive designs where cost sensitivity outweighs qualification requirements |
| TPSMD20A | DO-218AB (SMC) package; same VBR/VC specs; 500 W PPPM; AEC-Q101 qualified | Higher surge capacity but 2.3 mm height - unsuitable for ultra-low-profile layouts constrained to ≤1.0 mm | Choose TPSMD20A when higher energy absorption is required and board height allows ≥2.3 mm clearance |
Compared with SMAJ20A and TPSMD20A, the TPSMP20HE3/84A uniquely balances AEC-Q101 compliance, 1.0 mm profile, and 400 W surge capability-making it optimal for space-limited automotive modules where both reliability and form factor are critical.

FAQ
What is the clamping voltage of the TPSMP20HE3/84A at its rated peak pulse current?
The TPSMP20HE3/84A has a maximum clamping voltage (VC) of 29.1 V at 13.7 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value ensures downstream components remain within safe operating voltage limits during standardized automotive surge events. The TPSMP20HE3/84A achieves this clamping performance using patented PAR oxide-passivated chip technology for consistent dynamic impedance.
Is the TPSMP20HE3/84A qualified for automotive applications?
Yes, the TPSMP20HE3/84A is AEC-Q101 qualified and designated as high-reliability/automotive grade (HE3 suffix). It passes JESD201 Class 2 whisker testing and meets MSL Level 1 reflow requirements (260 °C peak), making it suitable for under-hood and powertrain applications. The TPSMP20HE3/84A is explicitly listed in Vishay's automotive-grade product documentation (Doc. #88471, Rev. 21-Oct-08).
What does the "HE3/84A" suffix indicate in TPSMP20HE3/84A?
The "HE3" suffix denotes RoHS-compliant, high-reliability/automotive grade construction with JESD201 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 preferred package coding system documented in the TPSMP series datasheet (Document Number 88471).
What is the standoff voltage (VWM) and leakage current specification for the TPSMP20HE3/84A?
The TPSMP20HE3/84A has a maximum standoff voltage (VWM) of 16.2 V and guarantees reverse leakage current ≤1.0 µA at that voltage and 25 °C ambient. At elevated junction temperature (TJ = 150 °C), leakage remains ≤5.0 µA. These values ensure minimal power loss and signal integrity impact in always-on automotive circuits. The TPSMP20HE3/84A maintains these parameters across its qualified operating temperature range.
How does the DO-220AA (SMP) package of the TPSMP20HE3/84A compare to standard SMA packages in terms of board space?
The DO-220AA (SMP) package of the TPSMP20HE3/84A measures 2.67 mm × 1.15 mm with 1.0 mm typical height, offering ~45 % lower profile than DO-214AC (SMA) packages (~2.3 mm height). Its compact footprint and low mass enable high-density placement near connectors and ICs without interfering with adjacent components or shielding cans. The TPSMP20HE3/84A's SMP package is optimized for modern automotive PCBs where Z-axis clearance is strictly limited.
