Product details
Overview
TPSMP13AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the PAR® family, designed for high-reliability overvoltage protection of sensitive electronics. It features a 12.4 V to 13.7 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 µs), 22.0 A peak pulse current (IPPM), and clamps to ≤18.2 V at rated surge - ideal for safeguarding automotive sensor signal lines and microcontroller I/O ports against ESD and load dump transients.
For engineers reviewing the TPSMP13AHM3/84A datasheet, TPSMP13AHM3/84A pinout, TPSMP13AHM3/84A application, or TPSMP13AHM3/84A equivalent, key selection criteria include its AEC-Q101 qualification, DO-220AA (SMP) package with 1.0 mm profile, TJ = 185 °C rating, unidirectional polarity, and MSL Level 1 reflow compatibility - all critical for automotive-grade board-level surge protection design.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver low incremental surge resistance and fast response time (<1 ns), enabling effective clamping of fast-rising transients such as ISO 7637-2 pulses and IEC 61000-4-2 ESD events. Its unidirectional configuration supports DC-biased signal line protection without forward conduction interference.
The device operates across -65 °C to +185 °C junction temperature range and maintains stable VBR with a +0.081 %/°C temperature coefficient. Its 1.0 mm height and matte tin-plated terminals meet J-STD-002 and JESD 22-B102 solderability requirements for automated SMT assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise clamping onset threshold for reliable overvoltage detection |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| IPPM | 22.0 A (10/1000 µs waveform) - peak surge current it safely shunts without failure |
| VC @ IPPM | ≤18.2 V - clamped voltage during full-rated surge, limiting stress on downstream ICs |
| PPPM | 400 W - peak pulse power handling capacity for transient energy absorption |
| TJ max | +185 °C - enables operation in under-hood automotive environments and high-power density PCBs |
| Package | DO-220AA (SMP) - ultra-low-profile surface-mount package with 1.0 mm typical height |
Pinout & Package
TPSMP13AHM3/84A is housed in a DO-220AA (SMP) package: a two-terminal, unidirectional surface-mount device with cathode indicated by a color band. The package measures 2.67 mm × 1.27 mm × 1.0 mm (L × W × H) and features matte tin-plated leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side connection | Connected to ground or lower-potential rail in unidirectional protection configuration |

|
Use Scenario: Overvoltage suppression on 5 V/12 V DC input rails of wall adapters and external power supplies subject to AC line transients. IC Role / Device Role / Timing Role: Primary-stage TVS connected between input rail and chassis ground to limit surge energy entering secondary-side regulation circuitry. Use Value: Withstands 40 A non-repetitive forward surge (IFSM) and dissipates 2.5 W continuously, supporting robust front-end protection without thermal shutdown. |
Use Scenario: ESD and cable discharge protection for USB 2.0 data lines and VBUS in head unit and telematics control units. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on VBUS line to suppress ±15 kV contact ESD per IEC 61000-4-2 without signal distortion. Use Value: Achieves <1 ns response time and 185 °C TJ rating, enabling placement adjacent to USB connectors in thermally dense infotainment assemblies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same DO-214AC (SMA) package; lower PPPM (400 W same), but higher VC (21.5 V) and larger footprint (4.5 mm × 2.7 mm) | Limited to non-automotive or less space-constrained designs due to 2.2 mm height and no AEC-Q101 certification | Choose SMAJ13A only if board layout allows larger package and AEC-Q101 is not required. |
| TPSMD13A | Same Vishay PAR® family, DO-218AB package; identical VBR, VC, and PPPM, but 2.4 mm height and higher IPPM (24.9 A) | Better suited for high-energy surge environments (e.g., alternator output lines), but incompatible with ultra-low-profile layouts | Select TPSMD13A when higher surge margin is needed and 1.4 mm extra height is acceptable. |
Compared with SMAJ13A and TPSMD13A, the TPSMP13AHM3/84A uniquely combines AEC-Q101 qualification, 1.0 mm profile, and DO-220AA packaging - making it the only option among the three validated for space-limited automotive sensor nodes requiring zero-height overhead and production-grade reliability.

FAQ
What is the breakdown voltage tolerance for TPSMP13AHM3/84A?
The TPSMP13AHM3/84A has a specified breakdown voltage (VBR) range of 12.4 V to 13.7 V at 1.0 mA test current, corresponding to a ±5 % tolerance. This tight tolerance ensures predictable clamping behavior in precision protection circuits and is confirmed in the Electrical Characteristics table of Vishay document 88471. The device's temperature coefficient of +0.081 %/°C further guarantees stable VBR performance across its full -65 °C to +185 °C operating range.
Is TPSMP13AHM3/84A suitable for bidirectional signal line protection?
No, the TPSMP13AHM3/84A is strictly unidirectional and must be used with correct polarity - cathode connected to the protected line, anode to ground. It does not provide symmetrical clamping for AC or bidirectional signals. For bidirectional protection, Vishay offers the TPSMP13CA variant (not TPSMP13AHM3/84A), which features complementary breakdown characteristics. Using TPSMP13AHM3/84A on AC-coupled lines risks forward conduction and potential damage during negative half-cycles.
Does TPSMP13AHM3/84A require derating at elevated ambient temperatures?
Yes, TPSMP13AHM3/84A requires derating per Figure 2 in Vishay document 88471: its peak pulse power (PPPM) decreases linearly above 25 °C ambient, reaching ~50 % of rated 400 W at 125 °C. However, its 185 °C maximum junction temperature allows continued operation in high-ambient environments when PCB copper area and thermal vias are optimized per the recommended 5.0 mm × 5.0 mm pad layout. Steady-state power dissipation remains fixed at 2.5 W up to 75 °C ambient.
What is the meaning of the "HM3/84A" suffix in TPSMP13AHM3/84A?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. The "/84A" indicates packaging: 7-inch plastic tape-and-reel with 3000 units per reel, using carrier tape code 84A. This ordering format is defined in the "Ordering Information" section of Vishay document 88471 and confirms full compliance traceability for automotive production use - distinct from non-HM3 variants that lack AEC-Q101 validation.
Can TPSMP13AHM3/84A be used in place of TPSMP13A without layout changes?
Yes - TPSMP13AHM3/84A is a direct replacement for TPSMP13A in the same DO-220AA (SMP) package with identical pinout, dimensions, and electrical specifications. The HM3 suffix adds halogen-free, RoHS, and AEC-Q101 compliance but does not alter form, fit, or function. Layouts designed for TPSMP13A (e.g., marking code AVP, VBR 12.4–13.7 V) are fully compatible with TPSMP13AHM3/84A, and no PCB modifications are required for drop-in substitution in automotive or industrial applications.
