Product details
Overview
TPSMC8.2AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 8.2 V nominal breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 124 V maximum clamping voltage at 124 A peak pulse current, and operates up to +185 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the TPSMC8.2AHE3_A/H datasheet, TPSMC8.2AHE3_A/H pinout, TPSMC8.2AHE3_A/H application, or TPSMC8.2AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 124 V clamping performance at rated surge, TJ = 185 °C capability, and SMC package compatibility with high-reliability board layouts requiring MSL level 1 handling.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable breakdown behavior and low incremental surge resistance under repetitive transient stress. Its 10/1000 µs waveform response supports protection against inductive switching spikes and lightning-induced surges in DC power rails and low-voltage signal paths.
The device is optimized for automotive-grade reliability: it meets AEC-Q101 qualification, operates from –65 °C to +185 °C, and is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine). The cathode-band-marked SMC package ensures correct orientation during automated placement and soldering per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.79 V / 8.20 V / 8.61 V at 10 mA - defines precise voltage threshold where clamping initiates under transient stress |
| VWM | 7.02 V - maximum continuous reverse voltage before leakage exceeds 200 µA, sets safe operating margin below VBR |
| IPPM | 124 A (10/1000 µs) - peak surge current the device safely clamps without failure, directly tied to 1500 W PPPM rating |
| VC @ IPPM | 12.1 V - clamped voltage seen by protected circuit at 124 A surge, determines maximum stress on downstream components |
| TJ max | +185 °C - enables operation in under-hood automotive environments and high-power industrial enclosures without derating |
| Polarity | Unidirectional - provides reverse-biased clamping only; requires correct cathode-anode orientation relative to protected line polarity |
| MSL Level | Level 1 (J-STD-020) - allows unlimited floor life and reflow up to 260 °C peak, simplifying SMT manufacturing flow |
Pinout & Package
TPSMC8.2AHE3_A/H uses the SMC (DO-214AB) surface-mount package: molded epoxy case with matte tin-plated leads, 0.305" × 0.220" body, cathode indicated by a color band. Leads are solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference; carries full surge current during clamping event |
| Cathode | Protected line connection point | Connected to line being protected (e.g., 5 V rail or sensor output); voltage referenced to anode during conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics use including engine control units and ADAS power domains |
| 1500 W peak pulse power (10/1000 µs) | Supports robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surge events |
| Low clamping ratio (VC/VBR ≈ 1.48) | Minimizes overvoltage stress on protected ICs while maintaining fast response and low leakage |
| 185 °C junction rating | Enables deployment in high-temperature zones without thermal derating or heatsinking |
| MSL Level 1 moisture sensitivity | Eliminates bake requirements and supports standard reflow profiles in high-volume production |

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), smaller SMB package (DO-214AA), 8.0 V VBR, 12.8 V VC at 49.1 A | Limited to lower-energy transients; not AEC-Q101 qualified; unsuitable for under-hood automotive use | Select when space-constrained layouts require smaller footprint and surge energy remains ≤600 W |
| TPSMC8.2AHE3_A/I | Identical electrical specs; differs only in packaging: 3500-unit 13" tape-and-reel vs. 850-unit 7" reel | No functional difference; same AEC-Q101 qualification, RoHS compliance, and thermal performance | Choose based on production volume and SMT line feeder configuration-not for performance differentiation |
Compared with SMBJ8.0A, TPSMC8.2AHE3_A/H delivers 2.5× higher surge power handling and automotive qualification; compared with TPSMC8.2AHE3_A/I, it offers identical protection performance but optimized for smaller batch procurement and 7" reel compatibility.

FAQ
What is the breakdown voltage tolerance for TPSMC8.2AHE3_A/H?
The TPSMC8.2AHE3_A/H has a specified breakdown voltage range of 7.79 V (min) to 8.61 V (max) at 10 mA test current, with 8.20 V nominal. This ±5% tolerance ensures consistent clamping initiation across production lots while allowing design margin for worst-case transient thresholds in automotive and industrial applications.
Is TPSMC8.2AHE3_A/H compatible with lead-free reflow processes?
Yes, TPSMC8.2AHE3_A/H is fully compatible with lead-free reflow. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and its MSL Level 1 rating permits exposure to peak temperatures up to 260 °C without preconditioning-making it suitable for standard Pb-free SAC305 reflow profiles.
Does TPSMC8.2AHE3_A/H support bidirectional transient suppression?
No, TPSMC8.2AHE3_A/H is unidirectional only. It clamps reverse-biased transients between cathode and anode. For bidirectional protection (e.g., AC lines or data buses), a separate bidirectional TVS such as SMAJ8.0CA must be selected-TPSMC8.2AHE3_A/H cannot be used in symmetrical configurations.
What is the maximum leakage current of TPSMC8.2AHE3_A/H at its stand-off voltage?
At 7.02 V stand-off voltage (VWM) and 25 °C, TPSMC8.2AHE3_A/H exhibits a maximum reverse leakage current of 200 µA. At elevated temperature (TJ = 150 °C), leakage increases to 2000 µA-still within specification and verified per the datasheet's electrical characteristics table.
How does the temperature coefficient affect TPSMC8.2AHE3_A/H's breakdown voltage?
TPSMC8.2AHE3_A/H has a typical VBR temperature coefficient (αT) of +0.056 %/°C. This means VBR increases linearly with junction temperature: at 125 °C, VBR rises by approximately 5.6%, shifting from 8.20 V to ~8.65 V-critical for designs operating near thermal limits where clamping threshold must remain predictable.
