Product details
Overview
TPSMA13AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching and lightning-induced transients on power rails and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 22.0 A peak pulse current (IPPM), 18.2 V maximum clamping voltage (VC) at IPPM, 400 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the TPSMA13AHE3_A/H datasheet, TPSMA13AHE3_A/H pinout, TPSMA13AHE3_A/H application, or TPSMA13AHE3_A/H equivalent, key selection criteria include unidirectional polarity, SMA (DO-214AC) package compatibility, AEC-Q101 qualification status, TJ = 185 °C capability, and clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping across temperature. Its unidirectional structure enables forward conduction during overvoltage events while maintaining low leakage (<1.0 µA at VWM = 11.1 V) and fast response time to sub-nanosecond transients.
The device is rated for 400 W peak pulse power (10/1000 µs), 40 A non-repetitive forward surge current (8.3 ms half-sine), and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is AEC-Q101 qualified (HE3 suffix), RoHS-compliant, and halogen-free option available via HM3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - defines precise voltage threshold at which avalanche conduction begins under 1.0 mA test current |
| VWM | 11.1 V - maximum continuous reverse operating voltage before significant leakage occurs |
| VC @ IPPM | 18.2 V - clamped voltage seen by protected circuit during 22.0 A 10/1000 µs surge, limiting stress on downstream components |
| IPPM | 22.0 A - peak surge current capability at rated clamping voltage, derated above 25 °C per fig. 2 |
| PPPM | 400 W - transient energy handling capacity using standard 10/1000 µs waveform, critical for automotive load-dump immunity |
| TJ max. | +185 °C - enables operation in high-temperature engine bay or industrial control environments without derating |
| Polarity | Unidirectional - provides reverse-biased clamping only; requires correct orientation relative to DC rail polarity |

Applications
| Automotive Sensor Protection | Industrial Power Input Stage |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from ESD and load-dump transients in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between signal line and ground, absorbing surges before they reach sensitive input pins. Use Value: Limits transient voltage to ≤18.2 V during 22 A surges, preserving signal integrity and preventing latch-up in 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding 24 V DC input rails of PLC modules and motor drives against inductive kickback and lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power entry point, coordinated with upstream fuses and downstream regulators. Use Value: Clamps 400 W transients within 1 ns, reducing risk of MOSFET gate oxide failure and enabling robust 24 V system design. |
| Consumer Power Adapter Output | Telecom Line Interface |
Use Scenario: Secondary-side surge suppression on 12 V/19 V outputs of AC-DC adapters used in laptops and monitors. IC Role / Device Role / Timing Role: Final-stage TVS on regulated output, guarding against reverse polarity connection and hot-plug transients. Use Value: Withstands 40 A 8.3 ms forward surge (IFSM), ensuring survival during accidental short-circuit recovery events. |
Use Scenario: Protection of Ethernet PHY interfaces and DSL line drivers against induced surges on outdoor-facing telecom ports. IC Role / Device Role / Timing Role: Bidirectionally referenced unidirectional clamp (cathode to VCC, anode to GND) on differential pair common-mode path. Use Value: Delivers 18.2 V clamping at 22 A while maintaining <1.0 µA leakage at 11.1 V, minimizing standby power impact. |
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 (12.4–13.7 V), but SMB package (DO-214AA); 600 W PPPM; 30 A IPPM | Higher surge rating but larger footprint; less suitable for space-constrained automotive modules | Select when higher pulse energy margin is required and PCB layout allows SMB size |
| 1.5KE13A | Through-hole TO-204AA (DO-41); same VBR/VC; 1500 W PPPM; 122 A IPPM | Not surface-mountable; incompatible with automated SMT assembly; used in legacy or high-energy industrial designs | Choose only for through-hole prototyping or where manual assembly and extreme surge capacity are prioritized |
Compared with SMBJ13A and 1.5KE13A, the TPSMA13AHE3_A/H offers optimal balance of AEC-Q101 qualification, SMA footprint compatibility, and 400 W surge handling - making it the preferred choice for new SMT-based automotive and industrial designs requiring production-grade reliability.

FAQ
What is the clamping voltage of the TPSMA13AHE3_A/H under a 10/1000 µs surge?
The TPSMA13AHE3_A/H has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 22.0 A using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream ICs see limited overvoltage stress during transient events. The TPSMA13AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is the TPSMA13AHE3_A/H AEC-Q101 qualified?
Yes, the TPSMA13AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number: 88405, Revision: 23-Jan-2024). The HE3 suffix explicitly denotes RoHS-compliant, AEC-Q101 qualified construction. This qualification covers stress tests including high-temperature reverse bias, high-temperature operating life, and temperature cycling - validating the TPSMA13AHE3_A/H for automotive under-hood applications.
What does the "HE3" suffix mean in TPSMA13AHE3_A/H?
The "HE3" suffix in TPSMA13AHE3_A/H indicates RoHS-compliant construction with AEC-Q101 qualification and meets JESD 201 Class 2 whisker resistance. The "_A/H" denotes revision code A and packaging in 7″ tape-and-reel (H = 1800 units per reel). This suffix distinguishes the TPSMA13AHE3_A/H from non-automotive variants and confirms its suitability for high-reliability production environments.
Can the TPSMA13AHE3_A/H be used in bidirectional protection circuits?
No, the TPSMA13AHE3_A/H is unidirectional only, as stated in the Vishay datasheet. It conducts in reverse bias during overvoltage events but blocks forward current beyond ~3.5 V. For bidirectional protection, two TPSMA13AHE3_A/H devices must be connected in series opposition, or a dedicated bidirectional TVS such as SMBJ13CA should be selected instead of the TPSMA13AHE3_A/H.
What is the maximum junction temperature rating for the TPSMA13AHE3_A/H?
The TPSMA13AHE3_A/H is rated for a maximum junction temperature (TJ) of +185 °C, enabling reliable operation in high-temperature environments such as engine control units, industrial motor drives, and enclosed power supplies. This rating is validated per AEC-Q101 testing and supports extended lifetime performance without derating up to this limit when mounted per recommended pad layout.
