Product details
Overview
TPSMP22-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for automotive-grade surge protection with 22 V breakdown voltage (VBR = 19.8–24.2 V), 400 W peak pulse power (10/1000 µs), 12.5 A peak pulse current (IPPM), and clamping voltage of 31.9 V at IPPM. It protects signal lines in automotive sensor units and ECUs.
For engineers reviewing the TPSMP22-E3/84A datasheet, TPSMP22-E3/84A pinout, TPSMP22-E3/84A application, or TPSMP22-E3/84A equivalent, key selection criteria include unidirectional polarity, 1.0 mm profile, MSL Level 1 rating, AEC-Q101-compatibility via HE3 suffix variants, and 185 °C max junction temperature.
Technical Context
This TVS diode uses patented PAR oxide passivated chip construction to achieve low incremental surge resistance and excellent clamping capability. Its fast response time and low forward voltage (VF = 2.5 V at 25 A) support robust protection of sensitive downstream ICs during ESD and load-dump transients.
Rated for automotive environments, it operates across –65 °C to +185 °C, meets RoHS/WEEE compliance, and is qualified per J-STD-020C MSL Level 1. The DO-220AA package enables automated placement and supports 260 °C solder dip for 40 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 19.8 V / 24.2 V - defines precise breakdown threshold for reliable triggering during overvoltage events |
| VWM | 17.8 V - maximum continuous reverse working voltage before leakage rises significantly |
| IPPM | 12.5 A - peak surge current it safely clamps under 10/1000 µs waveform, critical for ISO 7637-2 compliance |
| VC @ IPPM | 31.9 V - clamping voltage limiting stress on protected circuitry during worst-case surge |
| PPPM | 400 W - peak pulse power handling capacity, enabling protection against high-energy transients |
| TJ max | +185 °C - extended junction temperature rating supporting under-hood automotive deployment |
| IR @ VWM | 1.0 µA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity |
Pinout & Package
DO-220AA (SMP) surface-mount package with 1.0 mm typical height, matte tin-plated leads, UL-94V-0 epoxy, and cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to protected line side; conducts during forward-biased surge conditions |
| Cathode | Reverse-biased clamping node | Connected to ground or low-impedance return path; defines unidirectional clamping direction |
Key Features
| Feature | Design Value |

Applications
| Automotive Sensor Protection | ECU Power Line Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from ESD and coupled transients in engine bay or chassis modules. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between signal line and ground, triggered only during negative-going surges relative to ground. Use Value: Limits voltage to ≤31.9 V during 12.5 A surges, preventing latch-up or damage to 3.3 V/5 V interface ICs while maintaining <1.0 µA leakage at 17.8 V. | Use Scenario: Safeguarding 12 V power rails in body control modules and ADAS domain controllers against load-dump pulses (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Standoff device absorbing up to 400 W of transient energy within 10/1000 µs waveform, with fast response to limit voltage overshoot. Use Value: Clamps 12 V rail to 31.9 V during 12.5 A surge, preserving downstream DC-DC converters and microcontrollers rated for ≤36 V absolute max. |
| Infotainment Display Interface | ADAS Camera Data Lines |
Use Scenario: Shielding LVDS or FPD-Link III video data lines connecting head unit to digital displays from ESD events during assembly or field use. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp (CJ ~10–100 pF per datasheet curve) placed inline with differential pairs. Use Value: Maintains signal integrity with <1.0 µA leakage at 17.8 V and fast response, avoiding distortion of high-speed video signals up to 3 Gbps. | Use Scenario: Protecting MIPI CSI-2 serial data lanes from ESD in surround-view camera modules exposed to harsh environmental conditions. IC Role / Device Role / Timing Role: Cathode-grounded TVS suppressing negative transients on data lines while preserving common-mode noise rejection. Use Value: With 19.8–24.2 V VBR, it avoids false triggering during normal 2.5–3.3 V logic swings yet clamps fast ESD spikes to safe levels below receiver input limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-E3/5A | DO-214AC (SMA) package; 22 V VBR; 400 W PPPM; higher profile (2.29 mm); 1.0 µA IR at 17.8 V | Larger footprint; less suitable for ultra-thin automotive modules; same clamping voltage (31.9 V) | Select when legacy SMA layout exists or higher thermal mass is needed for repeated surge duty cycles |
| TPSMP22A-E3/84A | Same DO-220AA package; tighter VBR tolerance (20.9–23.1 V); identical PPPM, IPPM, and VC | Improved consistency for production binning; preferred where tighter breakdown spec improves system margin | Choose for new designs requiring tighter VBR control without changing PCB layout or thermal design |
Compared with SMAJ22A-E3/5A, TPSMP22-E3/84A offers 56 % lower profile and identical surge capability-critical for modern compact ECUs-while TPSMP22A-E3/84A provides tighter VBR tolerance for improved design margin without layout change.

FAQ
What is the breakdown voltage range of the TPSMP22-E3/84A?
The TPSMP22-E3/84A has a specified breakdown voltage (VBR) range of 19.8 V to 24.2 V at 10 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent triggering behavior across production lots while accommodating thermal drift and manufacturing tolerances. The TPSMP22-E3/84A maintains this specification under standard test conditions defined in Vishay Document 88937.
Is the TPSMP22-E3/84A suitable for automotive applications?
Yes, the TPSMP22-E3/84A is designed for automotive use, featuring a DO-220AA package qualified to MSL Level 1, operating junction temperature up to +185 °C, and compliance with RoHS/WEEE directives. While the E3 suffix denotes commercial grade, its construction-including PAR oxide passivation and 260 °C solder dip rating-supports under-hood deployment. For AEC-Q101 qualification, the HE3-suffix variant (e.g., TPSMP22HE3/84A) is required.
What is the clamping voltage of the TPSMP22-E3/84A at its rated peak pulse current?
The TPSMP22-E3/84A exhibits a maximum clamping voltage (VC) of 31.9 V at its rated peak pulse current (IPPM) of 12.5 A under a 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay Document 88937 and represents the upper bound of voltage seen by protected circuitry during worst-case surge events.
Does the TPSMP22-E3/84A have bidirectional or unidirectional polarity?
The TPSMP22-E3/84A is a unidirectional TVS diode, as explicitly stated in the Vishay datasheet features section. Its cathode is marked by a color band, and it conducts only during reverse-bias overvoltage conditions. It does not provide symmetrical clamping for both polarities-bidirectional protection requires a separate part such as TPSMP22A-E3/84A or dual-diode configurations.
What packaging format is used for the TPSMP22-E3/84A?
The TPSMP22-E3/84A is supplied in 7-inch diameter plastic tape and reel packaging, with a base quantity of 3000 units per reel (package code 84A). This format supports automated SMT placement and is compatible with standard pick-and-place equipment. The DO-220AA (SMP) case outline dimensions are fully documented in Figure 6 of Vishay Document 88937.
