Product details
Overview
TPSMC13AHE3_B/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 transients and lightning-induced surges on power and signal lines. It features 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 82.4 V maximum clamping voltage at 82.4 A peak pulse current, and operates up to +185 °C junction temperature - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the TPSMC13AHE3_B/H datasheet, TPSMC13AHE3_B/H pinout, TPSMC13AHE3_B/H application, or TPSMC13AHE3_B/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, SMC package mechanical data, and direct alternative part comparisons for high-reliability surge protection design.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under repeated surge stress. Its unidirectional polarity enables forward-biased operation during overvoltage events on DC-biased lines, and its 185 °C maximum junction temperature supports under-hood automotive deployment without thermal derating penalties.
The device meets JESD201 Class 2 whisker resistance and MSL Level 1 (260 °C reflow), with matte tin-plated terminals solderable per J-STD-002 and JESD22-B102. Its 10/1000 µs waveform response delivers sub-nanosecond turn-on and low incremental surge resistance (Rdyn ≈ 0.22 Ω), critical for protecting MOSFET gate drivers and microcontroller I/O pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V at 1 mA - defines precise voltage threshold where clamping initiates, enabling accurate overvoltage margining against 12 V nominal systems. |
| VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 2 µA; ensures no false triggering in 12 V rail applications. |
| IPPM | 82.4 A (10/1000 µs) - peak surge current capability that determines survivability against ISO 7637-2 Pulse 1/2a/5a transients. |
| VC | 18.2 V at IPPM - clamped voltage seen by protected IC; limits stress on downstream 20 V-rated components. |
| PPPM | 1500 W - peak pulse power handling capacity, validated on 8.0 mm × 8.0 mm copper pads, defining PCB layout thermal requirements. |
| TJ max | +185 °C - enables operation in engine control units and power inverters without external heatsinking or derating. |
| AEC-Q101 | Qualified - confirms reliability for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: SMC (DO-214AB), molded in UL 94 V-0 rated compound, cathode indicated by color band. Dimensions: 7.11 mm × 6.22 mm × 2.90 mm (L × W × H), with 3.20 mm minimum cathode/anode pad length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or surge clamping | Connected to lower-potential side of protected line (e.g., ground or return path); must route with low-inductance trace to minimize VL = L·di/dt overshoot. |
| Cathode | Current exit point during reverse-biased clamping | Connected to higher-potential line (e.g., 12 V rail or signal line); color band identifies this terminal for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Supports robust immunity to ISO 7637-2 Pulse 5a (load dump) in 12 V automotive systems without cascaded protection stages. |
| 185 °C maximum junction temperature | Eliminates thermal derating in under-hood ECUs and motor controllers, maintaining full surge rating across full operating range. |
| AEC-Q101 qualified (HE3 suffix) | Validates long-term reliability under automotive temperature cycling, humidity bias, and high-temperature reverse bias stress. |
| Low clamping ratio (VC/VBR = 1.40) | Minimizes overvoltage exposure to protected ICs - e.g., keeps 13 V-rated CAN transceivers below absolute maximum ratings during surge. |
| MSL Level 1, 260 °C reflow compatible | Enables single-pass lead-free assembly without moisture sensitivity concerns or baking requirements. |

The TPSMC13AHE3_B/H has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated 82.4 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88407 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 20 V absolute maximum rated ICs.
Is the TPSMC13AHE3_B/H qualified for automotive applications?
Yes, the TPSMC13AHE3_B/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in revision 19-Jan-2024 of datasheet 88407. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), validating its suitability for under-hood and powertrain applications.
What does the "HE3" suffix indicate in TPSMC13AHE3_B/H?
The "HE3" suffix in TPSMC13AHE3_B/H denotes RoHS-compliant construction and AEC-Q101 qualification per Vishay's ordering nomenclature. It distinguishes this variant from "HM3" (halogen-free + AEC-Q101) and non-qualified base parts, and confirms compliance with JESD201 Class 2 whisker resistance and MSL Level 1 reflow profile.
What is the maximum operating junction temperature for the TPSMC13AHE3_B/H?
The TPSMC13AHE3_B/H has a maximum operating junction temperature (TJ) of +185 °C, verified per Vishay's primary characteristics table and thermal derating curves in datasheet 88407. This enables uninterrupted operation in high-ambient environments such as engine compartments and industrial motor drives without power derating.
How does the TPSMC13AHE3_B/H compare to the SMAJ13A in terms of surge capability?
The TPSMC13AHE3_B/H delivers 1500 W peak pulse power (10/1000 µs), whereas the SMAJ13A is rated for only 400 W. This three-fold difference reflects distinct package thermal mass (SMC vs. SMA) and internal construction - making TPSMC13AHE3_B/H suitable for ISO 7637-2 Pulse 5a load dump protection, while SMAJ13A is limited to lower-energy transients like ESD or switching noise.
