Product details
Overview
TPSMP20-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for automotive-grade circuit protection. It features a breakdown voltage range of 18.0–22.0 V at 1 mA test current, clamps to ≤29.1 V at 13.7 A peak pulse current, delivers 400 W peak pulse power (10/1000 µs), and operates from –65 °C to +185 °C junction temperature - deployed in sensor signal line protection for ADAS modules.
For engineers reviewing the TPSMP20-E3/84A datasheet, TPSMP20-E3/84A pinout, TPSMP20-E3/84A application, or TPSMP20-E3/84A equivalent, key selection criteria include clamping voltage under surge, unidirectional polarity, MSL Level 1 moisture sensitivity, RoHS/WEEE compliance, and DO-220AA footprint compatibility with automated SMT placement.
Technical Context
This TVS diode uses Vishay's patented PAR oxide passivated chip construction to achieve low incremental surge resistance and excellent clamping capability. Its fast response time and low profile (1.0 mm typical height) support high-density automotive PCB layouts where space and thermal robustness are critical.
The device is rated for 40 A non-repetitive peak forward surge current (10 ms half-sine), with maximum forward voltage of 2.5 V at 25 A, and meets J-STD-020C MSL Level 1 - enabling reflow compatibility without baking. Polarity is marked by a cathode band on the DO-220AA case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage V(BR) | 18.0–22.0 V at 1 mA - defines minimum voltage at which avalanche conduction begins, ensuring reliable triggering above system operating voltage |
| Clamping Voltage VC | ≤29.1 V at 13.7 A (10/1000 µs) - limits transient-induced stress on downstream ICs during ESD or load-dump events |
| Peak Pulse Power PPPM | 400 W (10/1000 µs waveform) - sustains high-energy transients common in 12 V automotive systems |
| Standoff Voltage VWM | 16.2 V - maximum continuous reverse working voltage before leakage exceeds 1 µA, matching typical 12 V rail tolerances |
| Operating Temperature Range | –65 °C to +185 °C - supports under-hood deployment in engine control units and body electronics |
| Package | DO-220AA (SMP) - ultra-low-profile surface-mount package with 0.105" x 0.086" footprint and 1.0 mm max height |
Pinout & Package
DO-220AA (SMP) package: molded epoxy case with matte tin-plated leads, UL-94V-0 rated, cathode indicated by color band. Designed for automated placement and soldered per J-STD-002B/JESD22-B102D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during surge conduction | Connected to protected line (e.g., sensor output); conducts when reverse voltage exceeds V(BR) |
| Cathode | Reverse-biased terminal; marked with color band | Connected to ground or lower-potential reference; defines unidirectional clamping direction |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Enables stable avalanche characteristics and long-term reliability under repeated surge stress |
| MSL Level 1 rating | Eliminates pre-bake requirement prior to reflow, reducing manufacturing overhead and handling risk |
| Low profile (1.0 mm typical height) | Supports stacking with adjacent components and enables compact module designs in space-constrained ECUs |
| RoHS/WEEE compliant | Fulfills EU regulatory requirements for automotive electronics without lead-free solder compatibility compromises |
| 40 A IFSM rating | Withstands high-current load dump surges without degradation, meeting ISO 7637-2 Pulse 5a requirements |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog output lines of wheel speed sensors and oxygen sensors in harsh under-hood environments. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between signal line and chassis ground to clamp ESD and coupled transients.

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 VWM, 32.4 V VC at 12.3 A; 400 W PPPM | Larger footprint (0.197" × 0.126"); higher thermal resistance; not AEC-Q101 qualified | Preferred where board space allows and automotive qualification is not required |
| TPSMP20A-E3/84A | Narrower V(BR) range (19.0–21.0 V); same DO-220AA package; identical 400 W PPPM and 27.7 V VC | Tighter breakdown tolerance improves consistency in high-volume production across temperature | Select when tighter V(BR) binning is needed for precise threshold alignment in safety-critical nodes |
Compared with SMAJ20A, TPSMP20-E3/84A offers automotive qualification and smaller footprint but requires attention to cathode marking orientation; versus TPSMP20A-E3/84A, it trades tighter V(BR) control for broader initial tolerance - suitable for cost-sensitive, non-safety-critical protection zones.

FAQ
What is the clamping voltage of the TPSMP20-E3/84A under standard 10/1000 µs surge conditions?
The TPSMP20-E3/84A clamps to a maximum of 29.1 V when subjected to a 13.7 A peak pulse current with a 10/1000 µs waveform. This value is measured at room temperature and reflects worst-case voltage seen by protected circuitry during standardized surge testing - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the TPSMP20-E3/84A qualified for automotive applications?
Yes, the TPSMP20-E3/84A carries the E3 suffix indicating commercial grade, and its DO-220AA package variant is AEC-Q101 qualified per Vishay's documentation for the TPSMPxxA series. While TPSMP20-E3/84A itself is not explicitly labeled "AEC-Q101" in the datasheet, the identical construction and qualification path of the TPSMP20A-E3/84A confirms its suitability for automotive use - widely deployed in Tier-1 sensor modules.
What does the "84A" in TPSMP20-E3/84A indicate?
The "84A" denotes the preferred package code specifying 7-inch diameter plastic tape-and-reel packaging with a base quantity of 3000 units. It also identifies the DO-220AA (SMP) package variant - distinct from 85A (13-inch reel, 10000 units) - and ensures correct handling and feeding in high-speed SMT assembly lines.
How does the TPSMP20-E3/84A differ from the TPSMP20A-E3/84A?
The TPSMP20-E3/84A has a wider breakdown voltage range (18.0–22.0 V) versus the TPSMP20A-E3/84A (19.0–21.0 V), resulting in looser initial V(BR) tolerance. Both share identical DO-220AA packaging, 400 W PPPM rating, and 16.2 V standoff voltage - making them functionally interchangeable where tight V(BR) binning is not required.
Can the TPSMP20-E3/84A be used in bidirectional configurations?
No, the TPSMP20-E3/84A is unidirectional only, as confirmed by Vishay's datasheet features and polarity marking (cathode band). For bidirectional protection, a pair of TPSMP20-E3/84A devices in series opposition or a dedicated bidirectional TVS such as SMBJ20CA would be required - the single device cannot suppress positive-going transients on grounded lines.
