Product details
Overview
TPSMC10HE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping inductive switching transients and lightning-induced surges on power and signal lines. It features a 10 V nominal breakdown voltage (VBR = 9.5–10.5 V at 1 mA), 8.55 V stand-off voltage (VWM), 14.5 V maximum clamping voltage (VC) at 103 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the TPSMC10HE3/9AT datasheet, TPSMC10HE3/9AT pinout, TPSMC10HE3/9AT application, or TPSMC10HE3/9AT equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, low 20 μA reverse leakage at VWM, unidirectional polarity, and SMC package compatibility with high-reliability PCB layouts requiring MSL Level 1 reflow.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable clamping under repetitive surge stress and elevated ambient temperatures. Its 185 °C maximum junction temperature enables operation in under-hood automotive environments and industrial motor drive control units without thermal derating penalties up to 125 °C ambient.
The device delivers 14.5 V clamping voltage at 103 A (10/1000 μs), with <0.064 %/°C temperature coefficient of VBR, ensuring predictable overvoltage response across temperature. It meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 (260 °C peak reflow), supporting automated assembly in high-volume production.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 / 10.0 / 10.5 V at 1 mA - defines precise voltage threshold where avalanche conduction begins, critical for matching system overvoltage trip margins |
| VWM | 8.55 V - maximum continuous reverse operating voltage before leakage exceeds 20 μA, sets safe DC bias limit for protected line |
| VC @ IPPM | 14.5 V at 103 A - clamped voltage during worst-case surge, determines maximum stress on downstream ICs like MCUs or gate drivers |
| PPPM | 1500 W (10/1000 μs) - peak surge energy handling capacity, supports IEC 61000-4-5 Level 4 compliance when properly laid out |
| TJ max | 185 °C - enables sustained operation in high-temp zones (e.g., engine control modules), eliminating need for thermal margin derating |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation toward protected circuit side |
| MSL Rating | Level 1 per J-STD-020 - allows unlimited floor life and single reflow at 260 °C peak, simplifying SMT manufacturing flow |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic case with matte tin-plated leads; cathode indicated by color band; dimensions: 7.11 × 6.60 × 2.90 mm (L × W × H); mounting pad layout per Vishay spec: 8.13 mm × 4.69 mm overall, 3.20 mm minimum pad length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference; must be routed with minimal inductance to preserve clamping speed |
| Cathode | Protected line connection point | Connected to line being safeguarded (e.g., 12 V rail or CAN_H); color band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - supports use in ADAS sensors and body control modules without additional qualification |
| 185 °C junction rating | Enables direct placement near heat sources (e.g., power MOSFETs or motor drivers) without thermal throttling or external heatsinking |
| 1500 W peak pulse power | Withstands 103 A surge current (10/1000 μs), meeting ISO 7637-2 Pulse 1/2/5a and IEC 61000-4-5 4 kV combination wave requirements |
| Low 20 μA leakage @ VWM | Minimizes standby power loss in battery-powered systems (e.g., telematics modules), preserving system efficiency |
| MSL Level 1, 260 °C peak | Eliminates moisture sensitivity concerns and baking steps - reduces manufacturing cost and cycle time in high-mix SMT lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower PPPM (400 W), same SMC package, VC = 16.0 V @ 24.9 A, non-AEC-Q101 | Not qualified for automotive; suitable for consumer-grade power supplies with lower surge exposure | Select SMAJ10A only for cost-sensitive, non-automotive designs where 1500 W surge headroom is unnecessary |
| TPSMC10AHM3/9AT | Identical electrical specs; halogen-free molding compound and JESD201 Class 2 whisker rating - same AEC-Q101 qualification | No functional difference; used where RoHS + halogen-free compliance is mandated (e.g., EU automotive Tier 1 BOMs) | Choose TPSMC10AHM3/9AT when material compliance (halogen-free + RoHS) is contractually required alongside AEC-Q101 |
Compared with SMAJ10A and TPSMC10AHM3/9AT, the TPSMC10HE3/9AT offers the full 1500 W surge capability and AEC-Q101 qualification in a RoHS-compliant package - making it the preferred choice for automotive and industrial applications demanding both reliability and regulatory alignment.

FAQ
What is the maximum clamping voltage of the TPSMC10HE3/9AT under surge conditions?
The TPSMC10HE3/9AT has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 103 A with a 10/1000 μs waveform. This value is measured per standard test conditions and ensures downstream components such as microcontrollers or interface ICs remain within their absolute maximum voltage ratings during transient events. The TPSMC10HE3/9AT maintains this clamping performance across its full operating temperature range.
Is the TPSMC10HE3/9AT qualified for automotive applications?
Yes, the TPSMC10HE3/9AT is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control, body electronics, and ADAS sensor modules. The "HE3" suffix denotes RoHS-compliant construction and AEC-Q101 qualification per Vishay's ordering nomenclature. This qualification covers stress tests for temperature cycling, humidity, mechanical shock, and surge endurance - all validated for the exact TPSMC10HE3/9AT variant.
What does the "9AT" suffix mean in TPSMC10HE3/9AT?
The "9AT" suffix in TPSMC10HE3/9AT is a Vishay internal revision and packaging code indicating the specific tape-and-reel configuration and manufacturing lot traceability. It corresponds to the standard 7-inch reel packaging (850 units per reel) with the "H" package code and complies with JEDEC standards for moisture sensitivity and solderability. The TPSMC10HE3/9AT retains identical electrical and thermal specifications as other TPSMC10HE3 variants bearing different revision codes.
Can the TPSMC10HE3/9AT replace the TPSMC10A in existing designs?
Yes, the TPSMC10HE3/9AT is a direct replacement for the base TPSMC10A, sharing identical electrical characteristics, SMC (DO-214AB) package dimensions, and pinout. The "HE3" suffix adds AEC-Q101 qualification and RoHS compliance, making it suitable for upgraded automotive and industrial designs without layout or schematic changes. The TPSMC10HE3/9AT maintains the same 9.5–10.5 V VBR, 8.55 V VWM, and 14.5 V VC as the TPSMC10A.
What is the reverse leakage current of the TPSMC10HE3/9AT at its working voltage?
The TPSMC10HE3/9AT exhibits a maximum reverse leakage current (IR) of 20 μA at its stand-off voltage (VWM) of 8.55 V and ambient temperature of 25 °C. At elevated temperature (TJ = 150 °C), leakage increases to 200 μA - still within acceptable limits for most low-power sensor and control applications. This low leakage ensures minimal impact on system quiescent current, especially critical in battery-operated devices using the TPSMC10HE3/9AT.
