Product details
Overview
TPSMC8.2HE3_A/H 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 clamping voltage (VC) at IPPM, supporting automotive-grade protection in motor control and sensor interfaces.
For engineers reviewing the TPSMC8.2HE3_A/H datasheet, TPSMC8.2HE3_A/H pinout, TPSMC8.2HE3_A/H application, or TPSMC8.2HE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low clamping ratio (VC/VBR ≈ 1.65), and compatibility with high-reliability PCB layouts using 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for fast response (<1 ps typical) and low incremental surge resistance, enabling effective suppression of ESD and inductive switching spikes. Its unidirectional configuration allows integration into DC-biased power rails without reverse leakage concerns at VWM.
The device operates across -65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is qualified to AEC-Q101 for automotive under-hood applications and exhibits <200 μA reverse leakage at VWM and 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.38 V / 9.02 V - Ensures reliable triggering above 6.63 V operating rail while avoiding false trips during normal transients |
| VWM | 6.63 V - Maximum continuous reverse voltage before significant leakage; matches 5 V–6.5 V logic/sensor supply domains |
| VC @ IPPM | 12.5 V - Clamped voltage during 120 A surge; limits downstream IC stress to safe levels below 13.5 V absolute max ratings |
| PPPM | 1500 W - Sustains 10/1000 μs surge energy up to 1.5 J; suitable for ISO 7637-2 Pulse 1/2a/5a automotive load dump events |
| IFSM | 200 A - Withstands 8.3 ms half-sine surge without bond wire failure; supports high-current motor driver protection |
| TJ max | +185 °C - Enables placement near heat sources (e.g., power MOSFETs, engine control units) without derating |
| AEC-Q101 | Qualified - Validated for automotive use including temperature cycling, humidity bias, and mechanical shock per AEC standard |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, matte tin-plated leads, cathode indicated by color band. Complies with UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Lower PPPM (600 W), higher VC (12.8 V), same DO-214AA package but smaller pad layout | Limited to lower-energy transients (e.g., IEC 61000-4-5 Level 3); not AEC-Q101 qualified | Select SMBJ8.0A only for cost-sensitive consumer or industrial applications where 1500 W rating and automotive qualification are unnecessary |
| TPSMC8.2AHE3_A/H | Narrower VBR tolerance (±5 % vs. ±10 %), tighter VWM (7.02 V), identical package and AEC-Q101 status | Better suited for precision 6.8 V–7.2 V rails where tighter clamping threshold improves margin | Choose TPSMC8.2AHE3_A/H when design requires guaranteed VBR ≤ 8.61 V and minimal variation across temperature and lot |
Compared with SMBJ8.0A, TPSMC8.2HE3_A/H delivers 2.5× higher surge power and automotive qualification; compared with TPSMC8.2AHE3_A/H, it trades tighter VBR control for broader tolerance and lower unit cost in high-volume production.

FAQ
What is the maximum clamping voltage of the TPSMC8.2HE3_A/H under a 120 A transient?
The TPSMC8.2HE3_A/H has a maximum clamping voltage (VC) of 12.5 V when subjected to its rated 120 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuitry remains within safe voltage limits during standardized surge events. The TPSMC8.2HE3_A/H maintains this performance across its full operating temperature range.
Is the TPSMC8.2HE3_A/H suitable for automotive under-hood applications?
Yes, the TPSMC8.2HE3_A/H is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications such as engine control units, transmission control modules, and battery management systems. Its DO-214AB package and matte tin plating meet automotive reflow and corrosion requirements, and the TPSMC8.2HE3_A/H is validated for thermal cycling and humidity bias per AEC standards.
What does the "HE3_A/H" suffix indicate in TPSMC8.2HE3_A/H?
The "HE3" denotes RoHS-compliant, AEC-Q101-qualified construction with JESD 201 Class 2 whisker resistance; "A" indicates ±10 % VBR tolerance; "H" specifies packaging in 7-inch plastic tape and reel with 850 units per reel. This full suffix confirms compliance, tolerance grade, and delivery format-critical for production traceability and process validation of the TPSMC8.2HE3_A/H.
How does the TPSMC8.2HE3_A/H compare to bidirectional TVS diodes in signal line protection?
The TPSMC8.2HE3_A/H is unidirectional and intended for DC-biased lines like 12 V power rails or LIN bus signals referenced to ground. Unlike bidirectional devices, it avoids leakage during negative excursions and provides lower VC for positive surges. For AC-coupled or floating signals, a bidirectional TVS would be required-but the TPSMC8.2HE3_A/H offers superior clamping efficiency and lower capacitance in properly biased applications.
What PCB layout guidance applies to the TPSMC8.2HE3_A/H for optimal surge performance?
Vishay specifies mounting the TPSMC8.2HE3_A/H on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads at each terminal to achieve rated 1500 W pulse power. Minimize trace inductance by placing the device as close as possible to the protected node and grounding the cathode pad directly to a solid ground plane. Avoid thermal reliefs on pads to ensure mechanical and thermal robustness during surge events involving the TPSMC8.2HE3_A/H.
