Product details
Overview
TPSMC16AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 66.7 A peak pulse current (IPPM), and clamps to 22.5 V at rated surge. It is used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power systems.
For engineers reviewing the TPSMC16AHE3_A/I datasheet, TPSMC16AHE3_A/I pinout, TPSMC16AHE3_A/I application, or TPSMC16AHE3_A/I equivalent, key selection considerations include its AEC-Q101 qualification, 185 °C maximum junction temperature, unidirectional polarity, low clamping ratio (VC/VBR = 1.41), and RoHS-compliant matte tin-plated terminals solderable per J-STD-002.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive surge stress. Its 10/1000 µs waveform rating reflects standardized lightning/surge immunity testing per ANSI/IEEE C62.35, and thermal derating above 25 °C follows Fig. 2 in the datasheet.
The device operates as a voltage-clamping shunt protector: when reverse voltage exceeds VBR (15.2–16.8 V), it avalanches into low-impedance conduction, limiting transient energy to downstream circuitry. Its 3.5 V forward voltage at 100 A supports robust surge handling without latch-up, and MSL Level 1 rating confirms suitability for standard reflow profiles up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 13.6 V - maximum continuous reverse operating voltage before leakage rises significantly |
| PPPM | 1500 W - peak transient power dissipation capability with 10/1000 µs waveform, critical for IEC 61000-4-5 compliance |
| IPPM | 66.7 A - peak surge current handled at VC = 22.5 V, determines minimum trace width and PCB copper area needed |
| VC @ IPPM | 22.5 V - clamped voltage during full-rated surge, sets upper bound on protected circuit's voltage tolerance |
| TJ max. | +185 °C - enables operation in under-hood automotive or high-ambient industrial environments without thermal shutdown |
| Polarity | Unidirectional - protects against positive transients only; requires correct cathode orientation toward protected line |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic case meeting UL 94 V-0 flammability rating. Cathode identified by color band. Terminals are matte tin plated, solderable per J-STD-002 and JESD 22-B102, and qualified per JESD 201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to ground or low-side reference | Provides return path for surge current; must be routed with low-inductance connection to minimize VL = L·di/dt overshoot |
| Cathode | Current exit point during reverse avalanche; connected to protected line | Acts as clamping node - voltage at this terminal is limited to ≤22.5 V during 1500 W surge events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard |
| 185 °C junction rating | Enables use in engine control units, DC-DC converters, and motor drives where ambient exceeds 125 °C |
| 1500 W peak pulse power | Meets IEC 61000-4-5 Level 4 (4 kV) surge immunity requirements with margin for system-level design |
| Low incremental surge resistance | Minimizes VC rise under fast-rising transients, improving protection effectiveness for nanosecond-scale spikes |
| MSL Level 1 (260 °C peak) | Allows single-pass lead-free reflow without moisture-induced popcorn failure or delamination |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Protection |

IC Role / Device Role / Timing Role: Fast-response TVS between VBUS and GND to absorb plug/unplug transients and cable ESD. Use Value: 22.5 V clamping ensures USB PD sink ICs (e.g., TUSB320) remain within absolute maximum ratings during 15 kV air discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16AHE3/A | Same VBR (15.2–16.8 V), but lower PPPM = 600 W and smaller SMB (DO-214AA) package | Lower surge capacity suits consumer-grade 12 V rails; not recommended for automotive load dump | Select when space-constrained layout and <600 W surge immunity suffice; verify thermal pad area matches SMB footprint |
| TPSMC16AHM3_A/I | Identical electrical specs and SMC package; halogen-free, RoHS-compliant, AEC-Q101 qualified | No functional difference; differs only in material composition (halogen-free molding compound) | Choose for strict halogen-free compliance programs (e.g., EU automotive Tier 1); otherwise TPSMC16AHE3_A/I is fully interchangeable |
Compared with TPSMC16AHE3_A/I, SMBJ16AHE3/A offers reduced surge robustness in a smaller footprint, while TPSMC16AHM3_A/I provides identical performance with halogen-free construction - enabling direct substitution where material compliance is mandated.

FAQ
What is the clamping voltage of the TPSMC16AHE3_A/I at its rated peak pulse current?
The TPSMC16AHE3_A/I clamps to a maximum of 22.5 V when subjected to its rated peak pulse current of 66.7 A (10/1000 µs waveform). This value is measured per standard test conditions in the datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The clamping voltage directly impacts system-level immunity margin and must be verified against downstream IC absolute maximum ratings. TPSMC16AHE3_A/I maintains this performance across its full operating temperature range.
Is the TPSMC16AHE3_A/I qualified for automotive applications?
Yes, the TPSMC16AHE3_A/I is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified variants. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 requirements. This qualification makes TPSMC16AHE3_A/I suitable for use in engine control units, body electronics, and ADAS power supplies where automotive-grade reliability is mandatory.
What is the meaning of the "A" in TPSMC16AHE3_A/I?
The "A" in TPSMC16AHE3_A/I is the revision code denoting the specific manufacturing revision level of the device, as defined in Vishay's ordering nomenclature. It appears after the base part number and before the packaging suffix ("_A/I"). Revision codes track process or material changes that do not affect form, fit, or function - for example, minor die process optimizations or mold compound revisions. TPSMC16AHE3_A/I remains fully compatible with prior "_B" or "_C" revisions unless explicitly noted otherwise in Vishay's change notifications.
Does the TPSMC16AHE3_A/I have bidirectional polarity?
No, the TPSMC16AHE3_A/I is unidirectional only, as explicitly stated in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It protects against positive voltage transients on the cathode side relative to the anode and must be oriented accordingly in-circuit. For bidirectional protection, a separate device such as the TPSMC16CAHE3_A/I would be required. Using TPSMC16AHE3_A/I in reverse-biased configurations risks permanent damage due to lack of symmetrical avalanche structure.
What is the maximum junction temperature rating for the TPSMC16AHE3_A/I?
The TPSMC16AHE3_A/I has a maximum junction temperature (TJ) rating of +185 °C, validated per Vishay's thermal characterization and AEC-Q101 qualification. This enables reliable operation in high-ambient environments such as under-hood automotive locations or enclosed industrial power supplies. Thermal design must ensure that power dissipation under surge conditions - combined with steady-state leakage and ambient temperature - does not exceed this limit. Derating curves in Figure 2 of the datasheet guide safe operation above 25 °C ambient.
