Product details
Overview
TPSMP8.2HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of low-voltage signal lines and power rails. It features a 7.38 V minimum breakdown voltage (VBR), 6.63 V stand-off voltage (VWM), 24.0 V clamping voltage (VC) at 200 A peak pulse current, and 300 W peak pulse power rating - optimized for automotive and industrial sensor interface protection.
For engineers reviewing the TPSMP8.2HM3/84A datasheet, TPSMP8.2HM3/84A pinout, TPSMP8.2HM3/84A application, or TPSMP8.2HM3/84A equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, ultra-low 1.0 mm profile, MSL Level 1 moisture sensitivity, and uni-directional polarity with cathode band marking - critical for space-constrained, high-temperature PCB layouts in automotive ECUs and industrial I/O modules.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2) and EFT (IEC 61000-4-4) transients. Its 10/1000 μs waveform-rated PPPM of 300 W and clamping ratio (VC/VBR) of ~3.25 support robust protection of 5 V–6.6 V logic interfaces without excessive overshoot.
The device operates within -65 °C to +185 °C junction temperature range and is rated for 40 A non-repetitive forward surge current (IFSM). Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and HM3 suffix confirms halogen-free, RoHS-compliant, and JESD 201 Class 2 whisker-tested construction.

Pinout & Package
TPSMP8.2HM3/84A is a two-terminal unidirectional TVS diode in DO-220AA (SMP) surface-mount package. Polarity is marked by a cathode band on the case; the terminal adjacent to the band is the cathode (K), and the opposite end is the anode (A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive input terminal in reverse-biased protection configuration | Connected to protected line (e.g., CAN_H, LIN, sensor output); conducts only during forward surge |
| Cathode (K) | Negative reference terminal; marked by color band | Connected to ground or lower-potential rail; provides clamping path during transient overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| 185 °C maximum junction temperature | Supports operation in engine control units, transmission modules, and other high-thermal-load locations |
| 1.0 mm typical height | Enables use in ultra-thin modules such as ADAS camera housings and compact motor drivers |
| MSL Level 1 (260 °C peak reflow) | Eliminates pre-baking requirement and simplifies standard lead-free SMT assembly |
| Low clamping ratio (VC/VBR ≈ 3.25) | Minimizes overvoltage margin needed for protected ICs, improving system-level robustness |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | DO-214AC (SMA) package; 8.0 V nominal VBR; 400 W PPPM; higher 2.3 mm height | Less suitable for ultra-low-profile designs; requires larger PCB pad area and higher reflow thermal mass | Choose SMAJ8.0A only if higher pulse power (400 W) is required and board height >2.3 mm is acceptable |
| TPSMA6.8A | DO-214AC (SMA) package; 6.8 V nominal VBR; 400 W PPPM; AEC-Q101 qualified; 2.3 mm height | Lower VWM (5.8 V) may cause leakage or false triggering in 6.6 V systems; not drop-in compatible | Prefer TPSMP8.2HM3/84A when VWM ≥ 6.6 V and height ≤ 1.0 mm are mandatory design constraints |
Compared with SMAJ8.0A and TPSMA6.8A, TPSMP8.2HM3/84A delivers identical AEC-Q101 qualification and superior height efficiency (1.0 mm vs. 2.3 mm), while matching 6.63 V VWM and 24.0 V clamping for precise 5 V–6.6 V rail protection - making it optimal for next-gen automotive modules where Z-axis space is constrained.

FAQ
What is the exact breakdown voltage range for TPSMP8.2HM3/84A?
The TPSMP8.2HM3/84A has a guaranteed breakdown voltage (VBR) range of 7.38 V to 9.02 V at 10 mA test current, per Vishay Document Number 88471. This range ensures consistent clamping behavior across production lots and supports reliable overvoltage detection in 5 V–6.6 V systems without premature conduction.
Is TPSMP8.2HM3/84A suitable for automotive under-hood applications?
Yes, TPSMP8.2HM3/84A is AEC-Q101 qualified and rated for a maximum junction temperature of +185 °C, making it suitable for under-hood automotive applications such as engine control units, transmission control modules, and body electronics where ambient temperatures exceed 125 °C.
Does TPSMP8.2HM3/84A have a bidirectional configuration option?
No, TPSMP8.2HM3/84A is strictly unidirectional, as confirmed in the "FEATURES" section of the datasheet. For bidirectional protection, Vishay offers separate part numbers such as TPSMP8.2CA; the "A" suffix in TPSMP8.2HM3/84A denotes ±5 % VBR tolerance, not polarity.
What is the moisture sensitivity level (MSL) rating for TPSMP8.2HM3/84A?
TPSMP8.2HM3/84A meets MSL Level 1 per J-STD-020, with a maximum lead-free reflow peak temperature of 260 °C. This eliminates the need for dry-packaging or baking prior to assembly, simplifying manufacturing for high-volume SMT lines.
How does the clamping voltage of TPSMP8.2HM3/84A compare to its breakdown voltage?
At 200 A peak pulse current (10/1000 μs), TPSMP8.2HM3/84A clamps to 24.0 V - resulting in a clamping ratio (VC/VBR) of approximately 3.25 using the minimum VBR of 7.38 V. This ratio reflects efficient transient energy absorption with minimal overshoot into protected circuitry.
