Product details
Overview
TPSMC16AHE3/9AT 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 a 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 TPSMC16AHE3/9AT datasheet, TPSMC16AHE3/9AT pinout, TPSMC16AHE3/9AT application, or TPSMC16AHE3/9AT equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C maximum junction temperature, unidirectional polarity, low clamping ratio (VC/VBR = 1.41), and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable performance under high-temperature stress. Its 10/1000 µs waveform response delivers consistent clamping behavior during inductive switching transients and lightning-induced surges.
The device operates across -65 °C to +185 °C junction temperature range and meets JESD201 Class 2 whisker resistance requirements. Its cathode-band-marked SMC package supports automated assembly and provides robust thermal dissipation on 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - ensures reliable triggering above system operating voltage while avoiding false trips |
| VWM | 13.6 V - maximum continuous reverse voltage before leakage exceeds 1 µA, compatible with 12 V rail systems |
| VC @ IPPM | 22.5 V - clamping voltage limits downstream component stress during 66.7 A transient events |
| PPPM | 1500 W - handles high-energy transients common in automotive load-dump and inductive switch-off scenarios |
| TJ max. | +185 °C - enables operation in under-hood and industrial environments without derating |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct orientation in series with protected line |
| MSL Level | Level 1 (260 °C peak reflow) - supports standard lead-free SMT processes without baking |

Applications
| Automotive Power Line Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients up to 120 V and inductive switching spikes. IC Role / Device Role: Unidirectional TVS placed between power rail and chassis ground to clamp overvoltage before it reaches downstream regulators and microcontrollers. Use Value: TPSMC16AHE3/9AT's 22.5 V clamping voltage and 1500 W rating ensure safe operation of 3.3 V/5 V logic circuits even during worst-case ISO 7637-2 Pulse 5a events. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops) in factory automation sensors from ESD and cable discharge events. IC Role / Device Role: Series-connected TVS on signal path to ground, limiting voltage excursion to ≤22.5 V during ±8 kV contact ESD per IEC 61000-4-2. Use Value: With 1 µA leakage at 13.6 V, TPSMC16AHE3/9AT avoids loading precision current-loop outputs while maintaining fast <1 ns response to transients. |
| Consumer Power Adapter Input Protection | MOSFET Gate Driver Transient Suppression |
Use Scenario: Safeguarding AC-DC adapter primary-side controllers from surge events on mains input lines. IC Role / Device Role: Parallel-connected TVS across bulk capacitor input to absorb line-to-line and line-to-ground surges per IEC 61000-4-5. Use Value: TPSMC16AHE3/9AT's 185 °C rating allows placement near hot components like transformers and MOSFETs without thermal compromise. | Use Scenario: Preventing gate oxide damage in high-side N-channel MOSFET drivers exposed to shoot-through or inductive kickback. IC Role / Device Role: Clamping diode between gate and source to limit VGS to ≤22.5 V during transient overvoltage. Use Value: Low clamping ratio (22.5 V / 16.0 V = 1.41) ensures gate voltage stays well below 25 V absolute maximum rating of most logic-level MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Lower peak pulse power (400 W), smaller SMA package (DO-214AC), same VBR range but higher VC (26.0 V) | Not suitable for automotive load-dump; limited to low-energy consumer ESD protection | Select SMAJ16A only for space-constrained, non-automotive designs where 400 W surge capacity suffices |
| 1.5KE16A | Through-hole TO-218 package, 1500 W rating, but no AEC-Q101 qualification and higher VC (25.5 V) | Requires PCB through-hole mounting; not compliant for automotive production | Choose 1.5KE16A only for prototyping or industrial equipment where AEC-Q101 is not mandated |
Compared with SMAJ16A and 1.5KE16A, TPSMC16AHE3/9AT uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, 1500 W capability, and 22.5 V clamping-making it the only option qualified for volume automotive production with minimal board area impact.

FAQ
What is the breakdown voltage tolerance for TPSMC16AHE3/9AT?
The TPSMC16AHE3/9AT has a specified breakdown voltage range of 15.2 V (minimum) to 16.8 V (maximum) at 1 mA test current, with 16.0 V as the nominal value. This ±5% tolerance ensures predictable turn-on behavior across production lots and temperature extremes, critical for consistent protection in 12 V automotive systems where VBR must exceed VWM (13.6 V) while remaining safely below downstream component ratings. The TPSMC16AHE3/9AT's tight distribution supports robust design margins without over-specifying clamping voltage.
Is TPSMC16AHE3/9AT RoHS-compliant and halogen-free?
Yes, TPSMC16AHE3/9AT carries the HE3 suffix, indicating it is RoHS-compliant and AEC-Q101 qualified-but not halogen-free. For halogen-free compliance, Vishay specifies the HM3 suffix (e.g., TPSMC16AHM3). The HE3 variant uses standard molding compound meeting UL 94 V-0 flammability rating and matte tin-plated leads solderable per J-STD-002. TPSMC16AHE3/9AT is fully traceable and documented per Vishay's material compliance policy (doc# 99912).
What is the maximum clamping voltage of TPSMC16AHE3/9AT at its rated peak pulse current?
The maximum clamping voltage (VC) of TPSMC16AHE3/9AT is 22.5 V when subjected to its rated peak pulse current (IPPM) of 66.7 A under the standardized 10/1000 µs waveform. This value is measured at the device terminals with specified mounting conditions (0.31" × 0.31" copper pads). The 22.5 V clamping level directly determines the maximum stress imposed on protected circuitry, making it a key parameter for validating safety margins in 12 V and 24 V systems. TPSMC16AHE3/9AT maintains this clamping performance across its full operating temperature range.
Does TPSMC16AHE3/9AT support automated optical inspection (AOI) after reflow?
Yes, TPSMC16AHE3/9AT's SMC (DO-214AB) package features a clearly defined cathode band and consistent body geometry that supports reliable AOI detection per IPC-A-610 Class 2/3 standards. Its matte tin plating provides high-contrast reflectivity, and the 0.220"–0.246" body width falls within standard AOI camera resolution thresholds. No special lighting or algorithm tuning is required-TPSMC16AHE3/9AT is routinely inspected in high-volume automotive PCB assembly lines using off-the-shelf AOI platforms.
How does the temperature coefficient of VBR affect TPSMC16AHE3/9AT performance at elevated temperatures?
The TPSMC16AHE3/9AT has a typical VBR temperature coefficient (αT) of +0.078 %/°C, meaning its breakdown voltage increases linearly with junction temperature. At 150 °C, VBR rises by ~9.8% over its 25 °C value (16.0 V → ~17.6 V), ensuring continued protection margin above VWM (13.6 V) across the full -65 °C to +185 °C range. This positive coefficient prevents premature conduction at high ambient, a critical feature for under-hood applications. TPSMC16AHE3/9AT's datasheet provides the exact formula for calculating VBR at any TJ.
