Product details
Overview
TPSMA10HE3/61T 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 10 V breakdown voltage (VBR = 9.5–10.5 V at 1 mA), 8.65 V stand-off voltage (VWM), 27.6 V clamping voltage (VC) at 27.6 A peak pulse current, 400 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - ideal for automotive power rail protection.
For engineers reviewing the TPSMA10HE3/61T datasheet, TPSMA10HE3/61T pinout, TPSMA10HE3/61T application, or TPSMA10HE3/61T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, clamping performance under 10/1000 µs surge, thermal derating above 25 °C, and compatibility with standard SMA PCB footprints used in automotive ECUs and industrial sensor interfaces.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its unidirectional architecture provides fast response time (<1 ns) and excellent clamping ratio (VC/VBR ≈ 2.76), enabling robust protection of downstream MOSFETs and ICs against inductive switching spikes and lightning-induced surges.
Rated for 400 W peak pulse power per 10/1000 µs waveform and 40 A non-repetitive forward surge current (8.3 ms half-sine), the device meets MSL Level 1 moisture sensitivity and supports reflow soldering up to 260 °C peak. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification per Vishay's automotive-grade product line.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 9.5–10.5 V at 1 mA - defines minimum voltage at which clamping initiates reliably during overvoltage events |
| Stand-off Voltage VWM | 8.65 V - maximum continuous operating voltage before leakage exceeds 5 µA, ensuring no false triggering |
| Clamping Voltage VC | 27.6 V at 27.6 A (10/1000 µs) - limits voltage seen by protected circuit during worst-case surge |
| Peak Pulse Power PPPM | 400 W (10/1000 µs) - determines energy-handling capability for transient suppression without failure |
| Junction Temperature Range | −65 °C to +185 °C - enables use in under-hood automotive environments and high-ambient industrial settings |
| Package | SMA (DO-214AC) - industry-standard surface-mount outline with 0.208" x 0.157" footprint and cathode band marking |
| AEC-Q101 Qualified | Yes (HE3 suffix) - validated for automotive reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
SMA (DO-214AC) package with axial lead configuration: molded plastic body, matte tin-plated terminals, cathode indicated by color band. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay's recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode of internal PN junction | Connected to protected circuit's higher-potential node (e.g., VCC, signal line); conducts during reverse-biased overvoltage |
| Anode | Cathode of internal PN junction | Typically tied to ground or lower-potential reference; completes clamping path during transient events |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | TJmax = +185 °C supports under-hood automotive placement without thermal derating penalties |
| Low clamping ratio | VC/VBR ≈ 2.76 ensures minimal overvoltage stress on protected ICs during 10/1000 µs surges |
| AEC-Q101 qualification | Validated for automotive applications including temperature cycling, HTRB, and ESD per JESD22-A110/A111 |
| MSL Level 1 rating | Enables single-reflow assembly without baking; peak reflow temperature up to 260 °C supported |
| Passivated anisotropic rectifier | Reduces leakage drift over temperature and improves long-term reliability in harsh environments |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |

Use Scenario: Protecting PoE-powered devices (e.g., IP cameras) from surge coupling into 48 V DC feed lines via Ethernet cables during lightning strikes. IC Role / Device Role / Timing Role: Unidirectional TVS installed on each DC input line relative to chassis ground to divert common-mode surges. Use Value: Withstands IEC 61000-4-5 Level 4 (4 kV) surges while maintaining <1 µA leakage at 48 V nominal, preserving power efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same VBR range (9.5–10.5 V), but SMB package (DO-214AA); 600 W PPPM rating; slightly higher VC (30.0 V) | Larger footprint (0.236" × 0.157") and 50 % higher peak power - suited for higher-energy surges where board space allows | Select SMBJ10A when system-level surge tests exceed 400 W requirements or when thermal margin must be increased via larger copper area |
| 1.5SMC10A | Same VBR, but SMC (DO-214AB) package; 1500 W PPPM; VC = 17.0 V at 88.2 A; higher IFSM (200 A) | Substantially higher surge handling and lower clamping voltage - intended for primary-side AC/DC input protection | Choose 1.5SMC10A only for front-end AC line or DC bus protection where 1500 W energy absorption is mandated; not drop-in for SMA layouts |
Compared with SMBJ10A and 1.5SMC10A, the TPSMA10HE3/61T delivers optimal balance of compact SMA footprint, AEC-Q101 qualification, and 400 W surge capability - making it the preferred choice for space-constrained, thermally demanding automotive and industrial PCBs where strict qualification and proven reliability are mandatory.

FAQ
What is the exact breakdown voltage range for TPSMA10HE3/61T?
The TPSMA10HE3/61T has a guaranteed breakdown voltage (VBR) range of 9.5 V to 10.5 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This specification is confirmed in Vishay's official datasheet (Document Number: 88405, Revision: 23-Jan-2024) and applies directly to the TPSMA10HE3/61T variant within the TPSMA6.8A–TPSMA43A family.
Is TPSMA10HE3/61T qualified to AEC-Q101?
Yes, TPSMA10HE3/61T is AEC-Q101 qualified - confirmed by the "HE3" suffix in its part number, which denotes RoHS-compliant and AEC-Q101-qualified construction per Vishay's ordering nomenclature. The qualification covers temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD) per JESD22-A114.
What is the clamping voltage of TPSMA10HE3/61T at its rated peak pulse current?
The TPSMA10HE3/61T clamps to a maximum of 27.6 V at 27.6 A peak pulse current (10/1000 µs waveform), as specified in the Electrical Characteristics table of the Vishay datasheet. This value defines the upper voltage limit imposed on protected circuits during standardized surge events.
Does TPSMA10HE3/61T have unidirectional or bidirectional polarity?
TPSMA10HE3/61T is unidirectional only - explicitly stated in the Features section of the Vishay datasheet. Its polarity is marked by a cathode band, and it conducts only when the cathode is at higher potential than the anode, making it suitable for DC rail and signal-line protection where reverse conduction is not required.
What is the maximum operating junction temperature for TPSMA10HE3/61T?
The TPSMA10HE3/61T supports a maximum junction temperature (TJ) of +185 °C, enabling reliable operation in under-hood automotive environments and high-ambient industrial enclosures. This rating is maintained across its full power derating curve per Figure 2 in the Vishay datasheet (88405).
