Product details
Overview
TPSMC10HE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping inductive switching and lightning-induced transients on power rails and signal lines. It features 10.0 V nominal breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 14.5 V maximum clamping voltage at 103 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMC10HE3_A/H datasheet, TPSMC10HE3_A/H pinout, TPSMC10HE3_A/H application, or TPSMC10HE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity, low clamping ratio (VC/VBR = 1.45), 1.0 µA max reverse leakage at VWM, and compatibility with reflow soldering per J-STD-020 MSL level 1.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable breakdown characteristics across temperature. Its 10/1000 µs waveform rating of 1500 W and 103 A peak pulse current (IPPM) are validated under 0.31" × 0.31" copper pad mounting per JEDEC standards.
The device exhibits a positive temperature coefficient of VBR (+0.064 %/°C), enabling predictable voltage drift over -65 °C to +185 °C operating range. It meets AEC-Q101 stress testing requirements and is RoHS-compliant with matte tin-plated leads qualified per JESD 201 Class 2 whisker test.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 V / 10.0 V / 10.5 V - ensures reliable conduction onset above system operating voltage while avoiding false triggering |
| VWM | 8.55 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA, matching 9–12 V automotive rail margins |
| VC @ IPPM | 14.5 V - clamps transients to safe levels for 12 V logic and MOSFET gate drivers during 103 A surge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower PPPM (400 W), same VBR (10.0 V), SMA package (smaller thermal mass) | Not rated for AEC-Q101; limited to consumer/industrial use below 150 °C | Select when cost and board space constrain 1500 W requirement and automotive qualification is unnecessary |
| TPSMC10AHM3_A/H | Identical electrical specs; halogen-free molding compound vs. RoHS-compliant only in HE3 version | Required for halogen-free compliance programs (e.g., EU WEEE, certain Tier 1 automotive OEMs) | Choose HM3 suffix where material composition mandates exceed RoHS-only requirements |
Compared with SMAJ10A and TPSMC10AHM3_A/H, the TPSMC10HE3_A/H delivers automotive-grade reliability (AEC-Q101), higher surge handling (1500 W vs. 400 W), and broader temperature operation (185 °C vs. 150 °C), making it optimal for under-hood and mission-critical industrial deployments.

FAQ
What is the clamping voltage of TPSMC10HE3_A/H at its rated peak pulse current?
The TPSMC10HE3_A/H has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current (IPPM) of 103 A using a 10/1000 µs waveform. This value is measured under standardized test conditions with 0.31" × 0.31" copper pads and defines the upper voltage limit imposed on protected circuitry during surge events. The TPSMC10HE3_A/H maintains this clamping performance across its full operating temperature range.
Is TPSMC10HE3_A/H qualified for automotive applications?
Yes, TPSMC10HE3_A/H is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature operating life, temperature cycling, unbiased highly accelerated stress testing, and mechanical shock - all required for automotive electronic components. The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified versions, making TPSMC10HE3_A/H suitable for engine control units, body electronics, and ADAS power domains.
What is the reverse leakage current specification for TPSMC10HE3_A/H at its stand-off voltage?
At its stand-off voltage (VWM) of 8.55 V and ambient temperature of 25 °C, the TPSMC10HE3_A/H exhibits a maximum reverse leakage current (IR) of 1.0 µA. At elevated junction temperature (TJ = 150 °C), leakage increases to a maximum of 200 µA - a value still compatible with low-power always-on systems. This low leakage preserves battery life in automotive and IoT applications where TPSMC10HE3_A/H is commonly deployed.
Does TPSMC10HE3_A/H have a defined polarity, and how is it marked?
TPSMC10HE3_A/H is a unidirectional TVS diode with clearly defined polarity: the cathode is identified by a color band on the SMC (DO-214AB) package body. During circuit operation, the cathode connects to the line being protected (e.g., 12 V rail), and the anode connects to ground. This configuration enables clamping action only for positive transients exceeding VBR; negative excursions are blocked. Polarity must be observed during PCB layout to ensure correct protection behavior.
What is the maximum operating junction temperature for TPSMC10HE3_A/H?
The TPSMC10HE3_A/H is rated for a maximum operating junction temperature (TJ) of +185 °C, significantly exceeding standard commercial-grade TVS diodes (typically +150 °C). This extended rating allows direct placement near heat-generating components such as power MOSFETs or DC/DC converters in automotive and industrial designs. Derating curves in the datasheet (Fig. 2) define allowable pulse power reduction above 25 °C ambient to maintain TJ ≤ 185 °C.
