Product details
Overview
TPSMP43HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-energy surge protection of sensitive electronics. It features 43 V breakdown voltage (VBR = 38.7–47.3 V), 400 W peak pulse power (10/1000 µs), 6.5 A peak pulse current (IPPM), and clamps to ≤61.9 V at rated surge - used in automotive power line and sensor interface protection.
For engineers reviewing the TPSMP43HM3/84A datasheet, TPSMP43HM3/84A pinout, TPSMP43HM3/84A application, or TPSMP43HM3/84A equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction rating, low-profile 1.0 mm height, and MSL Level 1 reflow compatibility - critical for under-hood automotive modules and industrial I/O protection.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced transients, and load-dump spikes. Its unidirectional configuration provides forward conduction path while clamping reverse surges above VWM = 34.8 V.
Rated for TJ = –65 °C to +185 °C and qualified per AEC-Q101, the device supports automotive-grade reliability with halogen-free, RoHS-compliant construction and matte tin-plated leads solderable per J-STD-002. The DO-220AA package delivers high power density in a footprint of 3.61 mm × 1.88 mm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 38.7 V min / 47.3 V max at 1 mA - defines precise clamping onset threshold for overvoltage events |
| Stand-off Voltage VWM | 34.8 V - maximum continuous reverse voltage before leakage exceeds 1 μA, ensuring no false triggering |
| Peak Pulse Power PPPM | 400 W (10/1000 µs waveform) - sustains high-energy transients without failure in automotive load-dump scenarios |
| Clamping Voltage VC | ≤61.9 V at 6.5 A IPPM - limits downstream voltage stress on protected ICs or MOSFETs |
| Junction Temperature Range | –65 °C to +185 °C - enables operation in engine bay, powertrain, and industrial control environments |
| Package | DO-220AA (SMP) - 3.61 mm × 1.88 mm surface-mount outline with 1.0 mm typical height for space-constrained PCBs |
Pinout & Package
TPSMP43HM3/84A is a two-terminal unidirectional TVS diode in DO-220AA (SMP) package. Polarity is marked by a cathode band on the body; the anode and cathode terminals are non-polarized in layout but functionally asymmetric - cathode connects to protected line, anode to ground or lower potential rail.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge input terminal | Connected to signal/power line requiring protection; conducts during reverse overvoltage |
| Anode | Reference/return terminal | Connected to system ground or low-impedance return path; completes clamping current loop |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics |
| 185 °C maximum junction temperature | Supports placement near heat sources (e.g., power converters) without derating penalties |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free assembly without moisture sensitivity concerns |
| Low profile (1.0 mm typical height) | Reduces board clearance issues in stacked or shielded enclosures |
| Halogen-free & RoHS-compliant | Meets global environmental compliance requirements for automotive and industrial OEMs |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against ISO 7637-2 load dump pulses up to 60 V. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between power rail and chassis ground. Use Value: Limits transient voltage to ≤61.9 V at 6.5 A, preventing damage to 36 V-rated DC-DC controllers and microcontrollers. |
Use Scenario: Shielding 4–20 mA current-loop sensors in factory automation from EFT and surge coupling. IC Role / Device Role / Timing Role: Fast-response shunt protector across sensor output terminals. Use Value: Sub-1 ns response ensures clamping occurs before transients propagate into analog front-end amplifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A-E3/61 | DO-214AC (SMA) package; 43 V VBR, 400 W PPPM, but 2.2 mm height vs. 1.0 mm | Less suitable for ultra-low-profile automotive modules due to taller package | Select when existing SMA footprint exists and height constraint is relaxed |
| TPSMP43A | Same family, tighter VBR tolerance (±5 %): 40.9–45.2 V vs. TPSMP43's 38.7–47.3 V; identical DO-220AA package | Better precision for systems requiring tighter clamping threshold control | Prefer for new designs where ±5 % VBR improves margin against false triggering |
Compared with SMAJ43A-E3/61, TPSMP43HM3/84A offers 55 % lower profile and AEC-Q101 qualification; compared with TPSMP43A, it trades VBR tolerance for cost-effective standard-grade performance while retaining identical mechanical and thermal specs.

FAQ
What is the exact breakdown voltage range for TPSMP43HM3/84A?
The TPSMP43HM3/84A has a specified breakdown voltage (VBR) range of 38.7 V minimum to 47.3 V maximum at 1 mA test current, per Vishay Document 88471. This wide tolerance reflects its standard-grade (non-A) variant designation and ensures robust clamping behavior across manufacturing variance and temperature drift.
Is TPSMP43HM3/84A AEC-Q101 qualified?
Yes, TPSMP43HM3/84A is AEC-Q101 qualified. The HM3 suffix denotes halogen-free, RoHS-compliant construction and full AEC-Q101 stress testing, including high-temperature operating life, temperature cycling, and ESD robustness - confirmed in the Vishay datasheet revision 22-Jul-16.
What does the "/84A" suffix mean in TPSMP43HM3/84A?
The "/84A" suffix in TPSMP43HM3/84A indicates the preferred packaging option: 7-inch diameter plastic tape and reel containing 3000 units. This is defined in the Ordering Information section of the Vishay datasheet and aligns with standard SMT handling requirements for automated placement.
Can TPSMP43HM3/84A be used in bidirectional configurations?
No, TPSMP43HM3/84A is strictly unidirectional. Its electrical structure and marking (cathode band only) support clamping in reverse bias only. For bidirectional protection, Vishay offers separate part numbers such as the SMBJ series - TPSMP43HM3/84A must not be substituted without circuit redesign.
What is the maximum clamping voltage of TPSMP43HM3/84A at rated surge current?
The maximum clamping voltage (VC) of TPSMP43HM3/84A is 61.9 V at its rated peak pulse current (IPPM) of 6.5 A, measured under the standard 10/1000 µs waveform. This value is guaranteed across temperature and ensures downstream components see no more than 61.9 V during worst-case transients.
