Product details
Overview
TPSMP8.2AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the PAR® family, designed for high-reliability automotive and industrial surge protection. It features a breakdown voltage of 7.79–8.61 V at 10 mA, clamps to ≤24.8 V at 200 A peak pulse current, and delivers 300 W peak pulse power with 185 °C junction capability.
For engineers reviewing the TPSMP8.2AHM3_A/I datasheet, TPSMP8.2AHM3_A/I pinout, TPSMP8.2AHM3_A/I application, or TPSMP8.2AHM3_A/I equivalent, this device is selected for robust ESD/surge protection on low-voltage signal lines and power rails where space-constrained, AEC-Q101-qualified, low-profile (1.0 mm height) TVS performance is required.
Technical Context
The TPSMP8.2AHM3_A/I uses passivated anisotropic rectifier technology to achieve fast response time and low incremental surge resistance. Its unidirectional configuration supports DC-biased protection paths, and its DO-220AA (SMP) package enables automated placement while meeting MSL Level 1 and JESD201 Class 2 whisker requirements.
Rated for operation from –65 °C to +185 °C, it maintains stable clamping under thermal stress and delivers consistent 300 W peak pulse power (10/1000 μs waveform) when mounted on standard 5.0 mm × 5.0 mm PCB copper pads - critical for automotive ECUs and sensor interfaces exposed to load dump or ISO 7637-2 transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - defines precise breakdown threshold for reliable triggering before downstream IC damage |
| VWM | 7.02 V - maximum continuous reverse operating voltage; ensures no leakage conduction during normal 5 V or 6.5 V rail operation |
| VC @ IPPM | ≤24.8 V at 200 A - clamping voltage limits protected circuit stress during 10/1000 μs surges |
| PPPM | 300 W - peak pulse power rating determines survivability against automotive load dump and ISO 16750-2 pulses |
| IR @ VWM | ≤50 μA - ultra-low reverse leakage preserves signal integrity and battery life in always-on sensor nodes |
| TJ max. | +185 °C - enables under-hood deployment without derating in engine control or ADAS modules |
| Package | SMP (DO-220AA) - 3.61 mm × 2.18 mm footprint with 1.0 mm profile, optimized for high-density automotive PCB layouts |
Pinout & Package
TPSMP8.2AHM3_A/I is housed in the SMP (DO-220AA) surface-mount package: cathode-indicating band on one end, anode on the opposite. The package has two terminals only, with no internal leads or multi-pin structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line; conducts transient energy to ground or lower-potential rail during overvoltage events |
| Anode | Reference/return node | Typically tied to system ground or negative rail; completes clamping path with minimal inductance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - eliminates need for additional qualification effort in Tier-1 designs |
| Junction passivation | Enhanced moisture and contamination resistance improves long-term reliability in humid or chemically aggressive under-hood environments |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning - simplifies SMT manufacturing flow |
| Low profile (1.0 mm typical height) | Enables placement beneath connectors or in tight board-to-board spacing - critical for compact ADAS camera modules |
| Halogen-free & RoHS-compliant | Meets global environmental compliance mandates including China RoHS II and EU Directive 2011/65/EU |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., temperature, pressure) in engine control units against ISO 7637-2 pulse 1, 2a, and 5a. IC Role / Device Role: Unidirectional TVS placed between signal line and ground to clamp transients before they reach the transceiver's input pins. Use Value: Clamps to ≤24.8 V at 200 A while maintaining <50 μA leakage at 7.02 V - prevents false triggering and preserves signal fidelity during normal operation. | Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers exposed to inductive kickback from solenoid valves and relay coils. IC Role / Device Role: Standoff-rated TVS on each input channel to absorb repetitive 400 V/1 A transients without degradation. Use Value: 300 W peak pulse power and 185 °C junction rating ensure sustained operation in hot control cabinets without thermal runaway. |
| Consumer Power Adapter Protection | Automotive Body Control Module (BCM) |
Use Scenario: Secondary-side overvoltage suppression on 5 V/9 V USB-C PD adapter outputs to meet UL 62368-1 surge immunity requirements. IC Role / Device Role: Low-leakage unidirectional TVS placed across output capacitor to limit transient overshoot during load step or fault recovery. Use Value: 7.02 V standoff allows clean regulation under nominal conditions; 24.8 V clamping protects connected devices during 1 kV/0.5 kΩ surge testing. | Use Scenario: Protecting LIN bus and power supply rails in door module ECUs subjected to battery reversal and jump-start conditions. IC Role / Device Role: Bidirectionally referenced but unidirectionally configured TVS on 12 V supply line to shunt reverse polarity energy via external diode or dedicated protection IC. Use Value: 185 °C rating and AEC-Q101 qualification ensure uninterrupted function during extended under-hood thermal cycling up to 125 °C ambient. |
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 | Higher VBR (7.6–8.4 V), same DO-214AC package, 400 W PPPM, but not AEC-Q101 qualified | Targeted at industrial/commercial systems without automotive qualification mandates | Select SMAJ8.0A only if AEC-Q101 is not required and higher clamping margin is acceptable |
| TPSMA6.8A | Lower VBR (6.45–7.14 V), same SMP package, 250 W PPPM, AEC-Q101 qualified | Better suited for 5 V logic rail protection where tighter VWM/VBR margin is needed | Choose TPSMA6.8A when protecting 3.3 V or 5 V circuits requiring lower trigger voltage and still needing automotive qualification |
Compared with SMAJ8.0A and TPSMA6.8A, the TPSMP8.2AHM3_A/I uniquely balances 8.2 V-class breakdown, 300 W surge capacity, AEC-Q101 compliance, and 1.0 mm profile - making it optimal for space-constrained automotive signal line protection where both precision triggering and thermal resilience are mandatory.

FAQ
What is the exact breakdown voltage range for TPSMP8.2AHM3_A/I?
The TPSMP8.2AHM3_A/I has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at a test current of 10 mA, measured per ANSI/IEEE C62.35. This range ensures consistent triggering behavior across production lots and temperature extremes, supporting reliable design margining for 8 V nominal systems.
Is TPSMP8.2AHM3_A/I compatible with lead-free reflow soldering?
Yes, TPSMP8.2AHM3_A/I meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 260 °C and is rated for standard lead-free soldering profiles. Its matte tin-plated terminals comply with JESD 22-B102 and support robust wetting without preconditioning.
Does TPSMP8.2AHM3_A/I support bidirectional transient suppression?
No, TPSMP8.2AHM3_A/I is a unidirectional TVS diode and must be used in DC-biased configurations only. For bidirectional protection, a separate device such as the TPSMP8.2CA or a back-to-back diode arrangement is required - the TPSMP8.2AHM3_A/I itself does not conduct in reverse bias beyond its specified VWM.
What is the maximum clamping voltage of TPSMP8.2AHM3_A/I under surge conditions?
The TPSMP8.2AHM3_A/I clamps to a maximum of 24.8 V when subjected to its rated peak pulse current of 200 A (10/1000 μs waveform). This value is verified per Fig. 1 and Table on page 2 of Vishay document 88471 and defines the upper voltage limit imposed on protected circuitry during transient events.
How does the SMP (DO-220AA) package of TPSMP8.2AHM3_A/I compare to SMA (DO-214AC)?
The SMP (DO-220AA) package of TPSMP8.2AHM3_A/I measures 3.61 mm × 2.18 mm with 1.0 mm typical height - 30 % smaller footprint and 40 % lower profile than SMA (DO-214AC). This enables higher board density and better thermal performance per unit area in automotive and portable applications.
