Product details
Overview
TPSMA13AHE3/5AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 22.0 A peak pulse current (IPPM), 18.2 V maximum clamping voltage (VC) at IPPM, and 400 W peak pulse power (10/1000 µs). It is used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the TPSMA13AHE3/5AT datasheet, TPSMA13AHE3/5AT pinout, TPSMA13AHE3/5AT application, or TPSMA13AHE3/5AT equivalent, key selection criteria include its unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low clamping ratio (VC/VBR ≈ 1.40), and compatibility with automated SMT assembly per J-STD-002.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by reverse-biased avalanche breakdown. Its passivated anisotropic rectifier technology ensures stable leakage performance up to 150 °C and enables reliable operation under repetitive surge conditions (0.01 % duty cycle).
The device is optimized for high-temperature environments with TJmax = 185 °C and meets MSL Level 1 (260 °C peak reflow). Its 10/1000 µs waveform response delivers consistent 400 W peak pulse power dissipation without thermal runaway when mounted on 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - defines precise avalanche initiation threshold for predictable clamping onset |
| VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 1 µA, ensuring no false triggering in normal operation |
| VC @ IPPM | 18.2 V - clamped voltage during 22.0 A transient, limiting downstream component stress to safe levels |
| IPPM | 22.0 A - peak surge current capability under standard 10/1000 µs waveform, validated at TA = 25 °C |
| PPPM | 400 W - transient energy absorption capacity, enabling robust protection against lightning and inductive switching spikes |
| TJmax | 185 °C - extended junction temperature rating supports under-hood automotive and high-ambient industrial use |
| Polarity | Unidirectional - provides reverse-bias surge suppression only; requires correct orientation in series with protected line |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic case with matte tin-plated leads. Cathode indicated by color band. Compliant with UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit; conducts during forward surge or ESD events |
| Cathode | Avalanche clamping terminal | Connected to higher-potential side; initiates controlled breakdown when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process reduces leakage drift over temperature and time, supporting long-term reliability in harsh environments |
| AEC-Q101 qualification | Validated for automotive-grade stress testing including HTGB, HTRB, and temperature cycling - required for engine control and ADAS modules |
| MSL Level 1 | Rated for peak reflow at 260 °C without moisture-induced damage, eliminating pre-bake requirements in SMT lines |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive CMOS inputs |
| 400 W peak pulse power | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV surge) on 12 V supply rails with proper PCB layout |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same VBR (13.0 V) and VC (22.0 V), but SMB (DO-214AA) package - 2.5 mm wider body, 0.5 mm taller, higher thermal mass | Lower power density; better thermal dissipation in high-duty-cycle scenarios but requires larger PCB area | Select SMBJ13A when board space allows and sustained surge repetition is expected beyond 0.01 % duty cycle |
| TPSMA13AHM3/5AT | Identical electrical specs and SMA package; differs only in halogen-free molding compound and JESD 201 Class 2 whisker resistance - same AEC-Q101 qualification | No functional difference; chosen where halogen-free compliance or enhanced whisker resistance is mandated by OEM spec | Choose TPSMA13AHM3/5AT when RoHS + halogen-free + whisker resistance are contractually required |
Compared with SMBJ13A and TPSMA13AHM3/5AT, the TPSMA13AHE3/5AT offers identical clamping performance in the smallest standardized SMA footprint, with RoHS compliance and AEC-Q101 validation - making it optimal for space-constrained automotive and industrial modules requiring rapid SMT throughput.

FAQ
What is the maximum clamping voltage of the TPSMA13AHE3/5AT under a 10/1000 µs surge?
The TPSMA13AHE3/5AT has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 22.0 A using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with specified PCB mounting conditions (0.2" × 0.2" copper pads), and represents the upper limit of voltage seen by downstream components during transient events.
Is the TPSMA13AHE3/5AT qualified for automotive applications?
Yes, the TPSMA13AHE3/5AT is AEC-Q101 qualified, as confirmed by Vishay's documentation for the HE3 suffix variant. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and humidity testing - making the TPSMA13AHE3/5AT suitable for engine control units, body electronics, and ADAS subsystems.
What does the "HE3" suffix indicate in TPSMA13AHE3/5AT?
The "HE3" suffix in TPSMA13AHE3/5AT denotes a RoHS-compliant, AEC-Q101-qualified version with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance. The "/5AT" denotes packaging in 7" tape-and-reel format with 1800 units per reel, per Vishay's ordering nomenclature.
How does the TPSMA13AHE3/5AT differ from the TPSMA13AHM3/5AT?
The TPSMA13AHE3/5AT and TPSMA13AHM3/5AT share identical electrical specifications, package (SMA), and AEC-Q101 qualification. The HM3 variant adds halogen-free molding compound and enhanced whisker resistance per JESD 201 Class 2 - otherwise, both are functionally interchangeable in designs where halogen-free content is not mandated.
What is the standoff voltage (VWM) and why is it critical for TPSMA13AHE3/5AT placement?
The TPSMA13AHE3/5AT has a standoff voltage (VWM) of 11.1 V, meaning it remains non-conductive with leakage <1 µA up to this reverse voltage. This parameter is critical because it must exceed the maximum normal operating voltage of the protected line - e.g., used on a 12 V rail only if system tolerances ensure rail never exceeds 11.1 V continuously, avoiding premature conduction and power loss.
