Product details
Overview
TPSMP15-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for automotive-grade ESD and surge protection. It features a breakdown voltage range of 13.5 V to 16.3 V at 1 mA test current, 22.0 V clamping voltage at 18.2 A peak pulse current, 400 W peak pulse power rating (10/1000 µs), and operates from –65 °C to +185 °C junction temperature - deployed in sensor signal line protection for ADAS camera modules.
For engineers reviewing the TPSMP15-E3/84A datasheet, TPSMP15-E3/84A pinout, TPSMP15-E3/84A application, or TPSMP15-E3/84A equivalent, key selection criteria include clamping voltage vs. protected IC's absolute maximum rating, unidirectional polarity alignment with DC-biased lines, DO-220AA footprint compatibility, and AEC-Q101 qualification status for automotive use.
Technical Context
The TPSMP15-E3/84A uses patented PAR oxide passivated chip construction to achieve low incremental surge resistance and excellent clamping capability under fast transient events. Its unidirectional configuration supports DC-biased signal paths such as CAN transceiver I/O or LIN bus lines, where reverse leakage must remain below 1.0 µA at 12.1 V standoff voltage.
Rated for MSL Level 1 per J-STD-020C and solderable at 260 °C for 40 seconds, the device is optimized for high-speed automated placement on automotive PCBs with 5.0 × 5.0 mm copper pads per terminal. Its 1.0 mm typical height enables compact layout in space-constrained ECUs and sensor housings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage V(BR) | 13.5 V min / 16.3 V max at 1 mA - defines minimum trigger threshold before clamping activation |

Use Scenario: Protecting MIPI CSI-2 differential clock and data lines in rear-view or surround-view cameras exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between connector and serializer IC input, clamping transients before they reach sensitive analog front-end. Use Value: 22.0 V clamping voltage ensures serializer IC (e.g., MAX9271) remains within its 24 V abs max rating during 400 W surges. |
Use Scenario: Safeguarding LIN bus transceiver inputs in door module ECUs subjected to battery reverse connection and jump-start events. IC Role / Device Role / Timing Role: Standoff-rated TVS on LIN RX/TX pins, absorbing reverse-polarity energy while maintaining <1 µA leakage at 12 V. Use Value: 12.1 V VWM allows full 12 V system operation; 185 °C TJ max supports placement near power relays. |
| Engine Control Unit Sensor Interface | Infotainment Display Data Lines |
Use Scenario: Shielding analog outputs of pressure and temperature sensors in engine bay against alternator ripple and ignition noise. IC Role / Device Role / Timing Role: Low-leakage TVS on 0–5 V sensor output lines, placed adjacent to ADC input to minimize trace inductance. Use Value: ≤1.0 µA IR at 12.1 V prevents offset error in 12-bit sensor signal chains operating at microamp bias currents. |
Use Scenario: Guarding eDP or LVDS video data lanes between head unit SoC and TFT display in hot-cold thermal cycling environments. IC Role / Device Role / Timing Role: High-speed unidirectional suppressor with <100 pF junction capacitance (typical), minimizing signal integrity impact. Use Value: DO-220AA footprint enables dense routing; 185 °C rating supports operation behind sun-loaded dash displays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/5A | DO-214AC package; 15 V nominal V(BR); 24.4 V VC at 17.4 A; 400 W PPPM; same AEC-Q101 grade | Larger footprint (2.79 mm height); higher clamping voltage increases risk for 24 V-tolerant receivers | Choose when board space allows larger package and clamping margin permits higher VC |
| TPSMAJ15A-QH | Same DO-214AC package; identical electrical specs; QH suffix denotes enhanced automotive screening beyond AEC-Q101 | Higher cost; tighter parametric binning; intended for safety-critical ADAS subsystems | Choose only if functional safety requirements (e.g., ISO 26262 ASIL-B) mandate extended screening |
Compared with SMAJ15A-E3/5A and TPSMAJ15A-QH, the TPSMP15-E3/84A delivers identical surge robustness in a 45 % lower profile package, enabling direct replacement in height-constrained automotive modules without layout revision - provided polarity and standoff voltage match system requirements.

FAQ
What is the clamping voltage of the TPSMP15-E3/84A at its rated peak pulse current?
The TPSMP15-E3/84A has a maximum clamping voltage (VC) of 22.0 V at 18.2 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected downstream ICs remain within their absolute maximum voltage ratings during surge events. The TPSMP15-E3/84A maintains this clamping performance across its full operating temperature range.
Is the TPSMP15-E3/84A qualified for automotive applications?
Yes, the TPSMP15-E3/84A carries the E3 suffix indicating commercial-grade AEC-Q101 qualification. It meets stress test requirements for temperature cycling, humidity, mechanical shock, and surge endurance defined in the AEC-Q101 standard. The TPSMP15-E3/84A is approved for use in non-safety-critical automotive systems including body control modules, lighting, and infotainment interfaces.
What does the "84A" in TPSMP15-E3/84A indicate?
The "84A" in TPSMP15-E3/84A is Vishay's preferred package code specifying 7-inch diameter plastic tape-and-reel packaging with a base quantity of 3000 units. This format is optimized for high-volume SMT assembly lines and ensures consistent feeding performance in pick-and-place equipment. The TPSMP15-E3/84A is not available in bulk or tube formats.
How does the DO-220AA package of the TPSMP15-E3/84A compare to DO-214AC in size?
The DO-220AA (SMP) package of the TPSMP15-E3/84A measures 2.67 mm × 1.15 mm with a 1.0 mm typical height, whereas DO-214AC (SMA) is 4.5 mm × 2.79 mm with 2.79 mm height. The TPSMP15-E3/84A occupies ~40 % less board area and is ~64 % lower in profile - critical for modern automotive modules with strict Z-axis constraints. Both share cathode-band polarity marking.
Can the TPSMP15-E3/84A be used in bidirectional configurations?
No, the TPSMP15-E3/84A is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts in reverse bias above V(BR) but blocks forward current beyond VF ≈ 2.5 V at 25 A. For bidirectional protection (e.g., AC-coupled USB or Ethernet lines), a separate symmetric TVS array or dual-diode configuration is required. Using the TPSMP15-E3/84A in bidirectional roles risks forward conduction failure.
