Product details
Overview
TPSMA10AHE3/61T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping fast voltage transients on power and signal lines. It features 10.0 V nominal breakdown voltage (VBR), 8.65 V stand-off voltage (VWM), 27.6 V maximum clamping voltage (VC) at 20 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 TPSMA10AHE3/61T datasheet, TPSMA10AHE3/61T pinout, TPSMA10AHE3/61T application, or TPSMA10AHE3/61T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, TJ = 185 °C capability, low clamping ratio (VC/VBR ≈ 2.76), and compatibility with automated SMT assembly under J-STD-020 MSL Level 1.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable breakdown characteristics and low incremental surge resistance. Its unidirectional architecture enables robust clamping of positive-going transients while maintaining low leakage (<5.0 µA at VWM) and fast response time (<1.0 ns).
The device is rated for 40 A non-repetitive forward surge current (IFSM) and exhibits a temperature coefficient of VBR of +0.064 %/°C, enabling predictable voltage shift across its -65 °C to +185 °C operating range - critical for under-hood automotive electronics and industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.50 / 10.0 / 10.50 V - defines precise clamping onset threshold at 1.0 mA test current |
| VWM | 8.65 V - maximum continuous reverse voltage before significant leakage begins |
| VC @ IPPM | 27.6 V at 20 A - clamped voltage during 10/1000 µs transient, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling capacity under standard lightning-surge waveform |
| TJ max. | +185 °C - enables use in high-temperature environments without derating penalties |
| Polarity | Unidirectional - protects against positive transients only; cathode band denotes terminal orientation |
| MSL Level | Level 1 per J-STD-020 - supports reflow soldering up to 260 °C peak without moisture-induced damage |
Pinout & Package
Package: SMA (DO-214AC), surface-mount plastic case with matte tin-plated leads, UL 94 V-0 rated molding compound, and cathode identification via color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode of internal PN junction | Connected to protected line; conducts during overvoltage to shunt energy to ground |
| Anode (non-banded end) | Cathode of internal PN junction | Typically tied to system ground or lower-potential reference plane |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Junction temperature rating | Up to +185 °C - eliminates need for thermal derating in engine control units and DC-DC converters |
| Clamping ratio (VC/VBR) | ≈2.76 - ensures tight voltage margin between operating and failure thresholds |
| Low leakage at VWM | <5.0 µA at 8.65 V - minimizes standby power loss in battery-powered systems |
| Fast response time | <1.0 ns - intercepts ESD and switching transients before IC damage occurs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between power input and ground to absorb >400 W surges.

Use Value: 185 °C operation ensures reliability in sealed telecom enclosures; AEC-Q101 qualification adds margin for long-life deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same VBR (10.0 V), but SMB (DO-214AA) package - larger footprint, 600 W PPPM | Higher power handling suits higher-energy transients; less suitable for space-constrained PCBs | Select when surge energy exceeds 400 W or board layout allows larger pad area |
| 1.5SMC10A | Same VBR, but SMC (DO-214AB) package - 1500 W PPPM, higher IPPM (123 A) | Designed for primary-side AC/DC or telecom line protection; not optimized for automotive SMT volume production | Prefer for front-end AC surge suppression where higher standoff and clamping margin are required |
Compared with SMBJ10A and 1.5SMC10A, the TPSMA10AHE3/61T delivers optimal balance of AEC-Q101 qualification, MSL Level 1 compatibility, compact SMA footprint, and precise 10 V clamping - making it the preferred choice for automotive and industrial SMT designs requiring validated high-temperature reliability.

FAQ
What is the breakdown voltage tolerance of the TPSMA10AHE3/61T?
The TPSMA10AHE3/61T has a specified breakdown voltage (VBR) range of 9.50 V (min) to 10.50 V (max) at 1.0 mA test current, with 10.0 V as the nominal value. This ±5 % tolerance ensures consistent clamping behavior across production lots and supports reliable design margining in automotive and industrial applications where precise overvoltage thresholds are critical.
Is the TPSMA10AHE3/61T AEC-Q101 qualified?
Yes, the TPSMA10AHE3/61T is AEC-Q101 qualified. The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, verified per the full stress test suite including HTGB, H3TRB, TC, and ESD. This qualification makes the TPSMA10AHE3/61T suitable for automotive powertrain, body electronics, and ADAS modules requiring certified component reliability.
What is the maximum clamping voltage of the TPSMA10AHE3/61T under surge conditions?
The TPSMA10AHE3/61T has a maximum clamping voltage (VC) of 27.6 V at 20 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value reflects worst-case device behavior under surge stress and defines the upper voltage limit imposed on protected circuitry - essential for ensuring downstream ICs remain within absolute maximum ratings during transient events.
Does the TPSMA10AHE3/61T support lead-free reflow soldering?
Yes, the TPSMA10AHE3/61T supports lead-free reflow soldering and is rated MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, and the HE3 suffix confirms whisker resistance per JESD 201 Class 2 - enabling robust, high-yield SMT assembly in modern electronics manufacturing.
How does the temperature coefficient affect the TPSMA10AHE3/61T's breakdown voltage?
The TPSMA10AHE3/61T has a VBR temperature coefficient (αT) of +0.064 %/°C. This means VBR increases linearly with junction temperature - e.g., at +125 °C, VBR rises by ~6.4 % above its 25 °C value. Designers must account for this shift when setting safety margins in high-temperature applications such as under-hood automotive electronics or enclosed industrial power supplies.
