Product details
Overview
TPSMC8.2HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for clamping voltage transients on power and signal lines. It features 7.38 V to 9.02 V breakdown voltage (VBR), 6.63 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 120 A peak pulse current (IPPM), and 12.5 V maximum clamping voltage (VC) - used to protect MOSFETs and ICs in automotive power supplies.
For engineers reviewing the TPSMC8.2HE3_A/I datasheet, TPSMC8.2HE3_A/I pinout, TPSMC8.2HE3_A/I application, or TPSMC8.2HE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction rating, low clamping ratio (VC/VBR ≈ 1.65), and MSL Level 1 reflow compatibility at 260 °C.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation. Its unidirectional architecture provides forward conduction only during reverse overvoltage events, enabling precise clamping without interfering with normal DC bias paths.
Rated for TJ = –65 °C to +185 °C, it supports automotive under-hood applications where thermal derating is critical. The device meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements, with matte tin-plated leads compliant to J-STD-002 and JESD22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.38 V / 9.02 V - defines minimum voltage at which clamping initiates reliably under 10 mA test current |
| VWM | 6.63 V - maximum continuous reverse working voltage before leakage exceeds 200 μA |
| VC @ IPPM | 12.5 V - clamped voltage seen by protected circuit during 120 A 10/1000 µs surge |
| PPPM | 1500 W - peak transient energy absorption capability per single non-repetitive pulse |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V supply rails in engine control modules against load dump transients up to ±120 V. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery+ and chassis ground to clamp surges before reaching MCU power inputs. Use Value: Limits rail voltage to ≤12.5 V during 120 A transients, preserving 5 V LDO regulator input integrity and avoiding brownout resets. | Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and switching noise in factory automation PLCs. IC Role / Device Role / Timing Role: TVS placed across differential signal pair (e.g., RS-485 A/B) to shunt fast transients while maintaining signal integrity. Use Value: Sub-1 ns response time prevents >10 kV ESD pulses from propagating into ADC front-end, eliminating data corruption. |
| Consumer Device USB Port Protection | Telecom Base Station DC Feed Protection |
Use Scenario: Safeguarding USB VBUS lines in portable docking stations exposed to hot-plug induced transients. IC Role / Device Role / Timing Role: Unidirectional TVS connected between VBUS and GND to absorb 10/1000 µs surges from cable coupling.

IC Role / Device Role / Timing Role: TVS installed at DC input connector to divert common-mode transients before entering DC-DC converter stage. Use Value: Withstands 200 A 8.3 ms half-sine surge (IFSM), preventing fuse blowout and maintaining uninterrupted base station uptime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Lower PPPM (600 W), same DO-214AA (SMB) package, VC = 12.3 V at 48.4 A | Not rated for AEC-Q101; limited to consumer/industrial use; insufficient for automotive load dump | Select only for cost-sensitive non-automotive designs with lower surge exposure |
| TPSMC8.2AHE3_A/I | ±5 % VBR tolerance (7.79–8.61 V) vs. ±10 % for TPSMC8.2HE3_A/I (7.38–9.02 V); identical package and ratings | Narrower VBR window improves clamping consistency in precision power rails | Choose when tighter voltage matching is required for regulated 5 V or 3.3 V system margins |
Compared with SMBJ8.0A, TPSMC8.2HE3_A/I delivers 2.5× higher surge power and automotive qualification; versus TPSMC8.2AHE3_A/I, it trades tighter VBR tolerance for broader voltage coverage and lower cost - ideal for general-purpose 12 V rail clamping.

FAQ
What is the breakdown voltage range of the TPSMC8.2HE3_A/I?
The TPSMC8.2HE3_A/I has a specified breakdown voltage (VBR) range of 7.38 V to 9.02 V at 10 mA test current, per Vishay Document 88407. This ±10 % tolerance reflects the nominal 8.2 V designation and ensures reliable clamping initiation across manufacturing lots and temperature extremes up to +185 °C junction temperature.
Is the TPSMC8.2HE3_A/I suitable for automotive applications?
Yes, the TPSMC8.2HE3_A/I is AEC-Q101 qualified and rated for TJ = –65 °C to +185 °C, making it suitable for under-hood automotive applications including engine control units, body control modules, and ADAS power supplies. Its 1500 W peak pulse power and 200 A IFSM meet ISO 7637-2 load dump requirements.
What does the "HE3_A/I" suffix mean in TPSMC8.2HE3_A/I?
The "HE3" denotes RoHS-compliant, matte tin-plated leads meeting JESD201 Class 2 whisker resistance; "A" indicates ±10 % VBR tolerance; "I" specifies packaging in 13-inch tape-and-reel with 3500 units per reel. This full suffix identifies the exact construction, compliance, and logistics configuration of the TPSMC8.2HE3_A/I part.
What is the maximum clamping voltage of the TPSMC8.2HE3_A/I during a surge event?
The TPSMC8.2HE3_A/I exhibits a maximum clamping voltage (VC) of 12.5 V at its rated peak pulse current (IPPM) of 120 A under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuits see no more than 12.5 V during worst-case transient events.
Does the TPSMC8.2HE3_A/I have bidirectional polarity?
No, the TPSMC8.2HE3_A/I is unidirectional only, as explicitly stated in the Vishay datasheet. It functions as a reverse-biased avalanche diode for clamping positive transients on lines referenced to ground. For AC or bipolar signal protection, a separate bidirectional variant (e.g., TPSMC8.2CA) would be required - not the TPSMC8.2HE3_A/I.
