Product details
Overview
TPSMP8.2HM3/85A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the eSMP® Series, designed for high-reliability overvoltage protection of sensitive electronics. It features a 7.38 V to 9.02 V breakdown voltage (VBR), 6.63 V stand-off voltage (VWM), 24.0 V clamping voltage at 200 A peak pulse current (VC), and 300 W peak pulse power rating - optimized for automotive and industrial signal-line protection.
For engineers reviewing the TPSMP8.2HM3/85A datasheet, TPSMP8.2HM3/85A pinout, TPSMP8.2HM3/85A application, or TPSMP8.2HM3/85A equivalent, key selection criteria include its AEC-Q101 qualification, DO-220AA (SMP) package with 1.0 mm profile, 185 °C junction temperature rating, low incremental surge resistance, and uni-directional polarity for DC-biased rail protection.
Technical Context
The TPSMP8.2HM3/85A employs passivated anisotropic rectifier technology to achieve fast response time and stable clamping under transient stress. Its junction passivation enables operation up to 185 °C and supports MSL Level 1 reflow compatibility (260 °C peak).
Designed for 10/1000 μs waveform compliance per ANSI/IEEE C62.35, it delivers 24.0 V clamping at 200 A IPPM with ≤50 μA reverse leakage at VWM, making it suitable for protecting microcontroller I/O, sensor interfaces, and power supply rails against ESD and lightning-induced surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.38 V / 9.02 V - ensures reliable triggering above normal operating voltage while avoiding false trips on ripple or noise |
| VWM | 6.63 V - maximum continuous reverse voltage before conduction begins; matches typical 5 V or 6.5 V logic/system rails |
| VC @ IPPM | 24.0 V at 200 A - limits transient voltage seen by downstream ICs during 10/1000 μs surge events |
| PPPM | 300 W - peak pulse power handling capability for short-duration transients per JEDEC standard waveforms |
| TJ max. | 185 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures |
| IR @ VWM | ≤50 μA - minimal leakage preserves battery life and signal integrity in always-on circuits |
| Package | DO-220AA (SMP) - surface-mount, low-profile (1.0 mm height), halogen-free, RoHS-compliant, AEC-Q101 qualified |
Pinout & Package
TPSMP8.2HM3/85A uses the DO-220AA (SMP) package: a compact, molded surface-mount case with matte tin-plated leads, cathode indicated by a color band, and footprint optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to protected line (e.g., signal or supply rail); conducts during reverse-biased surge |
| Cathode | Clamping reference / ground connection | Connected to system ground or low-impedance return; defines polarity and clamping threshold |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.5A | Higher VBR (7.65–8.45 V), same DO-214AC package, 400 W PPPM rating | Less precise VWM margin for 5 V systems; better suited for 8–9 V supply rails | Select SMAJ8.5A when higher surge power handling is required and board layout allows larger DO-214AC footprint |
| TPSMA6.8A | Lower VBR (6.45–7.14 V), same AEC-Q101 qualification, DO-214AC package, 400 W PPPM | Better fit for 3.3 V or 5 V logic rails with tighter clamping margin but reduced standoff headroom | Choose TPSMA6.8A where lower clamping voltage is prioritized over VWM margin in low-voltage microcontroller I/O protection |
Compared with SMAJ8.5A and TPSMA6.8A, the TPSMP8.2HM3/85A offers superior space efficiency (DO-220AA vs. DO-214AC), identical AEC-Q101 qualification, and optimal VBR/VWM balance for 5 V–6.5 V automotive and industrial signal lines - making it the preferred choice when PCB area and thermal reliability are constrained.

FAQ
What is the breakdown voltage range of the TPSMP8.2HM3/85A?
The TPSMP8.2HM3/85A has a specified breakdown voltage (VBR) range of 7.38 V minimum to 9.02 V maximum at 10 mA test current. This range ensures robust triggering above typical 5 V or 6 V system rails while avoiding premature conduction due to noise or ripple. The value is measured per ANSI/IEEE C62.35 standards using a square-wave pulse, and the TPSMP8.2HM3/85A maintains this specification across its full operating temperature range.
Is the TPSMP8.2HM3/85A suitable for automotive applications?
Yes, the TPSMP8.2HM3/85A is AEC-Q101 qualified and rated for junction temperatures up to 185 °C, making it fully suitable for under-hood and cabin automotive applications. Its DO-220AA package meets MSL Level 1, and its passivated anisotropic rectifier structure ensures stable clamping performance across thermal cycling and humidity bias tests. The TPSMP8.2HM3/85A is explicitly listed in Vishay's automotive-grade product documentation for use in sensor, infotainment, and body-control modules.
What is the clamping voltage of the TPSMP8.2HM3/85A at its rated peak pulse current?
The TPSMP8.2HM3/85A clamps to a maximum of 24.0 V at its rated peak pulse current of 200 A (10/1000 μs waveform). This clamping voltage is guaranteed under standardized test conditions with 5.0 mm × 5.0 mm copper pads per terminal and represents the maximum voltage imposed on protected circuitry during a transient event. The low dynamic impedance of the TPSMP8.2HM3/85A ensures repeatable clamping performance across multiple surge events.
Does the TPSMP8.2HM3/85A have polarity markings, and how is it oriented on the PCB?
Yes, the TPSMP8.2HM3/85A features a visible cathode band on the molded case, indicating the cathode terminal. During PCB layout, the cathode must be connected to the system ground or lowest-potential reference node, while the anode connects to the line being protected. This orientation is essential because the TPSMP8.2HM3/85A is a unidirectional device - reverse-biasing it relative to the protected circuit renders it non-functional for transient suppression.
What packaging configuration does the TPSMP8.2HM3/85A ship in?
The TPSMP8.2HM3/85A ships in 13-inch diameter plastic tape and reel packaging, with a base quantity of 10,000 units per reel (ordering code "85A"). This format supports high-speed automated pick-and-place assembly and complies with EIA-481 standards. The HM3 suffix confirms halogen-free, RoHS-compliant construction and JESD201 Class 2 whisker resistance - all verified for the TPSMP8.2HM3/85A per Vishay's official documentation.
