Product details
Overview
TPSMP22HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of signal lines and power rails. It features 22 V nominal breakdown voltage (VBR = 19.8–24.2 V), 400 W peak pulse power (10/1000 µs), 12.5 A peak pulse current (IPPM), 31.9 V clamping voltage (VC), and AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMP22HM3/84A datasheet, TPSMP22HM3/84A pinout, TPSMP22HM3/84A application, or TPSMP22HM3/84A equivalent, this device is selected for robust ESD/surge protection in space-constrained, high-temperature environments-especially where TJ = 185 °C operation, MSL Level 1 reflow compatibility, and low-profile mounting (1.0 mm height) are required.
Technical Context
The TPSMP22HM3/84A employs passivated anisotropic rectifier technology to achieve fast response time and low incremental surge resistance. Its unidirectional configuration enables integration into DC-biased circuits with defined polarity, such as power supply inputs and sensor signal paths.
Designed for automotive-grade reliability, it supports continuous operation up to +185 °C junction temperature and meets JESD201 Class 2 whisker resistance. The DO-220AA package provides mechanical robustness and thermal performance suitable for automated SMT placement on FR-4 PCBs with 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 19.8 V / 24.2 V - ensures reliable triggering above 17.8 V stand-off while tolerating manufacturing variation |
| VC @ IPPM | 31.9 V - limits downstream voltage stress during 12.5 A transient events |
| PPPM | 400 W (10/1000 µs) - sustains high-energy surges common in automotive load-dump and ISO 7637-2 tests |
| IFSM | 40 A - withstands 10 ms half-sine surge without failure, supporting inrush and fault-current handling |
| TJ max | +185 °C - enables under-hood deployment without derating in harsh thermal environments |
| VWM | 17.8 V - blocks normal operating voltage while allowing margin for ripple and tolerance |
| Leakage @ VWM | 1.0 µA - minimizes standby power loss in battery-powered systems |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control units against load dump transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery rail and DC-DC input, absorbing energy before it reaches downstream regulators. Use Value: Withstands 400 W pulses and clamps to ≤31.9 V, preventing regulator overvoltage failure while maintaining AEC-Q101 compliance. | Use Scenario: Safeguarding analog outputs of pressure or temperature sensors in factory automation PLCs exposed to cable-induced surges. IC Role / Device Role / Timing Role: TVS placed at sensor connector interface, shunting fast transients (<1 ns rise time) before they couple into precision ADC front-ends. Use Value: 12.5 A IPPM and 31.9 V VC ensure signal integrity remains intact during 1 kV/500 A surge events per IEC 61000-4-5. |
| Consumer USB Power Delivery Protection | Automotive Camera Module ESD Protection |
Use Scenario: Guarding 5 V/9 V/15 V USB PD power paths in portable docking stations against hot-plug and ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS installed between USB-C CC/VBUS lines and PMIC input, providing sub-nanosecond response. Use Value: 1.0 µA leakage at 17.8 V VWM avoids quiescent current penalty; 1.0 mm profile fits compact USB-C port layouts. | Use Scenario: Shielding MIPI CSI-2 data lines and 12 V bias supply in rear-view camera modules from ESD and ignition noise. IC Role / Device Role / Timing Role: Dual placement: one TPSMP22HM3/84A on power rail, another on shielded coax outer conductor to divert common-mode surges. Use Value: AEC-Q101 qualification and 185 °C rating ensure reliability across full vehicle temperature range (-40 °C to +125 °C ambient). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-E3/61 | DO-214AC (SMA) package; 22 V VBR; 400 W PPPM; 13.9 A IPPM; 35.5 V VC | Higher clamping voltage (+3.6 V) and larger footprint (2.5 mm height) limit suitability in ultra-thin automotive modules | Select when legacy SMA layout exists and 3.6 V higher clamping is acceptable for protected IC's absolute maximum rating margin |
| SMCJ22AHE3/73 | DO-214AB (SMC) package; 22 V VBR; 1500 W PPPM; 61.5 A IPPM; 35.5 V VC | Higher power rating but 4.5 mm height and 7.1 mm length preclude use in space-constrained PCBs | Choose for industrial motor drives requiring >1 kW surge handling where board area permits larger SMC footprint |
Compared with SMAJ22A-E3/61 and SMCJ22AHE3/73, the TPSMP22HM3/84A delivers identical 22 V breakdown and 400 W rating in a 1.0 mm profile DO-220AA package-enabling automotive-grade protection where height and thermal mass are constrained, without compromising AEC-Q101 compliance or clamping performance.

FAQ
What is the breakdown voltage tolerance for TPSMP22HM3/84A?
The TPSMP22HM3/84A has a specified breakdown voltage range of 19.8 V to 24.2 V at 1.0 mA test current (VBR min/max), corresponding to ±10 % tolerance around the nominal 22 V rating. This tolerance is confirmed in the Electrical Characteristics table of Vishay document 88471, and applies directly to the TPSMP22HM3/84A variant.
Is TPSMP22HM3/84A suitable for bidirectional transient protection?
No, the TPSMP22HM3/84A is unidirectional only, as explicitly stated in the Features section of its datasheet. It must be oriented with cathode toward the protected line and anode to ground. For bidirectional protection, a separate symmetric TVS or back-to-back configuration would be required-TPSMP22HM3/84A itself does not support reverse-polarity surge suppression.
Does TPSMP22HM3/84A meet RoHS and halogen-free requirements?
Yes, the HM3 suffix in TPSMP22HM3/84A indicates halogen-free, RoHS-compliant construction, as documented in the Mechanical Data section of Vishay's 88471 datasheet. This includes compliance with JEDEC J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance testing.
What is the maximum clamping voltage of TPSMP22HM3/84A under surge conditions?
The maximum clamping voltage (VC) of TPSMP22HM3/84A is 31.9 V at 12.5 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured and guaranteed per the Electrical Characteristics table in Vishay document 88471 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can TPSMP22HM3/84A be used in reflow soldering processes?
Yes, TPSMP22HM3/84A is rated for MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, making it fully compatible with standard lead-free reflow profiles. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102 solderability requirements, ensuring reliable joint formation without special baking or handling.
