Product details
Overview
TPSMC16HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for clamping fast-rising voltage transients on power and signal lines. It features 1500 W peak pulse power (10/1000 μs), 14.4–17.6 V breakdown voltage (VBR), 12.9 V stand-off voltage (VWM), 23.5 V maximum clamping voltage (VC) at 63.8 A, and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the TPSMC16HE3_A/I datasheet, TPSMC16HE3_A/I pinout, TPSMC16HE3_A/I application, or TPSMC16HE3_A/I equivalent, this page delivers verified electrical specs, thermal limits (TJ = –65 °C to +185 °C), packaging details, real-world use cases, and validated alternative parts - all aligned with Vishay's 88407 specification document.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature reliability and low incremental surge resistance. Its unidirectional polarity enables precise reverse-biased clamping during overvoltage events on DC supply rails or signal paths.
It delivers 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), 3.5 V max forward voltage at 100 A, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance - confirming suitability for automated SMT assembly in harsh-environment designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.4 V / 17.6 V - defines minimum and maximum voltage at which device enters avalanche conduction under 1 mA test current |
| VWM | 12.9 V - maximum continuous reverse working voltage before leakage exceeds 1 μA; sets safe operating margin below clamping threshold |
| VC @ IPPM | 23.5 V - clamped voltage across device at 63.8 A peak pulse current; determines worst-case overvoltage seen by protected IC |
| PPPM | 1500 W - peak pulse power handling capability with 10/1000 μs waveform; defines transient energy absorption capacity |
| TJ max. | +185 °C - maximum junction temperature rating; enables operation in under-hood automotive or industrial environments |
| IFSM | 200 A - non-repetitive forward surge current (8.3 ms half-sine); supports robustness against load-dump or inductive kick events |
| Polarity | Unidirectional - provides reverse-biased clamping only; requires correct orientation relative to DC rail polarity |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, molded epoxy case meeting UL 94 V-0; cathode indicated by color band; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or lower-potential node; completes clamping path when cathode is tied to protected line |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V rail or signal trace); initiates avalanche conduction upon overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress requirements |
| 185 °C junction rating | Enables deployment in engine control units, body controllers, and other high-ambient-temperature locations without derating |
| 1500 W peak pulse power | Provides sufficient energy absorption to suppress ISO 7637-2 Pulse 1, 2a, 3a/b, and IEC 61000-4-5 surges in 12 V systems |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during transients, reducing stress on downstream MOSFETs, MCUs, and CAN transceivers |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profile usage without baking, simplifying manufacturing logistics |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|

IC Role / Device Role / Timing Role: Low-capacitance TVS connected across differential pair or single-ended output to ground. Use Value: Sub-100 ns response time and 23.5 V clamping prevent latch-up or parametric shift in precision ADC front-ends. |

IC Role / Device Role / Timing Role: Discrete TVS mounted adjacent to connector to shunt ESD current before reaching controller IC. Use Value: Meets IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) with minimal board space due to compact SMC footprint. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5AT | Lower PPPM (400 W), same VWM (12.8 V), higher VC (25.5 V), SMA package (smaller thermal mass) | Limited to lower-energy transients; not rated for automotive under-hood temperatures (TJ max = 150 °C) | Select when cost or board area is critical and surge energy remains below 400 W; verify thermal derating in enclosed enclosures. |
| 1.5SMC16A | Same PPPM (1500 W), identical VBR/VWM/VC, DO-214AB package, but no AEC-Q101 qualification or MSL Level 1 rating | Not approved for automotive production; suitable for industrial or consumer applications where qualification is not mandated | Choose for non-automotive designs requiring identical clamping performance without qualification overhead or tape-and-reel packaging constraints. |
Compared with SMAJ16A-E3/5AT and 1.5SMC16A, TPSMC16HE3_A/I uniquely combines AEC-Q101 qualification, +185 °C operation, MSL Level 1, and 1500 W clamping in a single DO-214AB variant - making it the preferred choice for Tier-1 automotive subsystems and high-reliability industrial controls where long-term field stability is mandatory.

FAQ
What is the breakdown voltage range of the TPSMC16HE3_A/I?
The TPSMC16HE3_A/I has a specified breakdown voltage (VBR) range of 14.4 V to 17.6 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures consistent avalanche initiation across production lots and temperature extremes, directly supporting design margin calculations for 12 V system protection. The TPSMC16HE3_A/I data is confirmed in Vishay document 88407, page 2.
Is the TPSMC16HE3_A/I suitable for automotive applications?
Yes, the TPSMC16HE3_A/I is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive modules including body control units, lighting drivers, and ADAS sensor interfaces. Its DO-214AB package, MSL Level 1 rating, and 1500 W pulse power align with ISO 16750-2 and ISO 7637-2 compliance requirements. All qualifications apply to the exact TPSMC16HE3_A/I part number.
What is the maximum clamping voltage of the TPSMC16HE3_A/I at its rated peak pulse current?
The TPSMC16HE3_A/I exhibits a maximum clamping voltage (VC) of 23.5 V at its rated peak pulse current (IPPM) of 63.8 A, tested with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is critical for verifying compatibility with downstream IC absolute maximum ratings. The parameter is explicitly listed in the Electrical Characteristics table for TPSMC16 on page 2 of document 88407.
Does the TPSMC16HE3_A/I have bidirectional or unidirectional polarity?
The TPSMC16HE3_A/I is unidirectional only, as stated in the Features section of Vishay document 88407. It functions as a reverse-biased avalanche diode, conducting only when cathode voltage exceeds anode voltage by more than VBR. This configuration is optimal for DC rail protection where polarity is fixed, and it avoids leakage issues associated with bidirectional variants in asymmetric bias conditions.
What packaging format is used for the TPSMC16HE3_A/I?
The TPSMC16HE3_A/I is supplied in 13-inch diameter plastic tape and reel, with a base quantity of 3500 units per reel (ordering code suffix "I"). The device uses the DO-214AB (SMC) package with matte tin-plated leads, compliant with J-STD-002 solderability and JESD 22-B102 whisker resistance Class 2. This packaging supports high-volume SMT assembly without preconditioning.
