Product details
Overview
TPSMB10AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 10 V breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 14.5 V maximum clamping voltage at 41.4 A, and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB10AHE3_A/I datasheet, TPSMB10AHE3_A/I pinout, TPSMB10AHE3_A/I application, or TPSMB10AHE3_A/I equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, 10 V VBR tolerance (±5%), and low 0.064 %/°C temperature coefficient of breakdown voltage.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under high-temperature stress (TJ = 185 °C), with junction passivation optimized for reliability in automotive and industrial environments. Its unidirectional configuration enables robust forward-biased surge handling while maintaining tight VBR tolerance (9.5–10.5 V at 1 mA) and low incremental surge resistance.
The device meets MSL Level 1 per J-STD-020 (260 °C peak reflow), has matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and is qualified to AEC-Q101 - confirmed by the HE3 suffix and ordering code structure in the Vishay documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 9.5 V min / 10.0 V nominal / 10.5 V max at 1 mA - defines precise clamping onset threshold for overvoltage events |
| Stand-off Voltage VWM | 8.55 V - maximum continuous reverse voltage before leakage exceeds 5 µA, ensuring no false triggering |
| Peak Pulse Power PPPM | 600 W at 10/1000 µs waveform - sustains high-energy transients without failure under standard test conditions |
| Maximum Clamping Voltage VC | 14.5 V at 41.4 A IPPM - limits downstream voltage stress during worst-case surge events |
| Junction Temperature Range | -65 °C to +185 °C - supports operation in under-hood automotive and high-ambient industrial environments |
| Temperature Coefficient αT | 0.064 %/°C - enables accurate VBR derating across temperature for reliable system-level design |
| AEC-Q101 Qualified | Yes - verified for automotive-grade reliability per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode indicated by color band. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); mounting pad layout requires 5.0 mm × 5.0 mm copper pads per terminal per Vishay thermal derating guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts surge current to ground when VRM exceeds VBR |
| Anode | Reference/ground return path | Typically tied to system ground plane; completes clamping loop during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Passivated anisotropic rectifier technology | Enables stable VBR and low leakage (<5 µA at VWM) across -65 °C to +185 °C operating range |
| 600 W peak pulse power (10/1000 µs) | Withstands repetitive 0.01 % duty cycle surges common in automotive load-dump and inductive switch-off scenarios |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and single-reflow processing at 260 °C peak without baking or special handling |
| AEC-Q101 qualification (HE3 suffix) | Validates reliability for automotive powertrain, body control, and ADAS subsystems requiring long-term field stability |
| Low 0.064 %/°C VBR tempco | Minimizes clamping voltage drift over temperature - critical for precision protection in wide-ambient applications |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against ISO 7637-2 pulse 1 (inductive switch-off) and pulse 2a (load dump). IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp transients before they reach LDOs or microcontrollers. Use Value: Limits rail voltage to ≤14.5 V during 41.4 A surges, preserving downstream IC integrity without sacrificing response time. | Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events in factory automation systems. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly at connector entry point to shunt fast transients before signal conditioning circuitry. Use Value: Sub-1 ns response ensures clamping occurs before sensitive op-amps or ADC inputs are overstressed. |
| Consumer Power Adapter Input Stage | Telecom Line Card Surge Suppression |
Use Scenario: Secondary-side DC output protection in wall adapters subjected to lightning-induced surges via connected devices. IC Role / Device Role / Timing Role: Standoff-rated TVS on 5–12 V output rails to prevent overvoltage damage to USB-PD controllers or charging ICs. Use Value: 8.55 V VWM allows safe operation under normal regulation while clamping at 14.5 V during transients. | Use Scenario: Front-end protection of Ethernet PHY interfaces or DSL line drivers exposed to induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Unidirectional TVS on differential pairs or bias rails to absorb common-mode energy without distorting signal integrity. Use Value: 600 W rating handles telecom-specific surge waveforms (IEC 61000-4-5) without degradation after repeated strikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMB package, 10 V VBR, but rated for 400 W PPPM (vs. 600 W); not AEC-Q101 qualified | Limited to commercial/industrial use; unsuitable for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and higher surge margin |
| TPSMB10AHM3_A/I | Identical electrical specs and AEC-Q101 qualification; halogen-free molding compound (HM3 vs. HE3) | Required where RoHS + halogen-free compliance is mandated (e.g., EU automotive Tier 1 supply chains) | Choose HM3 variant if material compliance drives BOM requirements over standard RoHS |
Compared with SMAJ10A and TPSMB10AHM3_A/I, the TPSMB10AHE3_A/I delivers superior 600 W surge capability and AEC-Q101 validation in a RoHS-compliant package - making it optimal for automotive power rail protection where both reliability and regulatory compliance are mandatory.

FAQ
What is the exact breakdown voltage range for TPSMB10AHE3_A/I at 1 mA test current?
The TPSMB10AHE3_A/I has a guaranteed breakdown voltage (VBR) range of 9.5 V minimum to 10.5 V maximum at 1 mA test current, with 10.0 V nominal. This ±5 % tolerance is confirmed in the Vishay Electrical Characteristics table (Document #88406, page 2) and applies across the full operating temperature range when derated per the provided αT coefficient.
Is TPSMB10AHE3_A/I AEC-Q101 qualified, and how is that reflected in the part number?
Yes, TPSMB10AHE3_A/I is AEC-Q101 qualified. The "HE3" suffix in the part number explicitly denotes RoHS-compliant and AEC-Q101-qualified construction, as stated in the Vishay Mechanical Data section. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT).
What does the "_A/I" suffix mean in TPSMB10AHE3_A/I?
The "_A/I" suffix indicates revision "A" and packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units. Per Vishay's Ordering Information table (page 3), "I" denotes the 13″ reel format, while "A" is the revision code - distinct from the HE3 qualification suffix which precedes it.
What is the maximum clamping voltage of TPSMB10AHE3_A/I, and at what current is it specified?
The maximum clamping voltage (VC) of TPSMB10AHE3_A/I is 14.5 V, measured at a peak pulse current (IPPM) of 41.4 A using the standardized 10/1000 µs waveform. This value is listed in the Electrical Characteristics table (Document #88406, page 2) and defines the upper voltage limit imposed on protected circuits during worst-case surge events.
Can TPSMB10AHE3_A/I be used in bidirectional configurations?
No, TPSMB10AHE3_A/I is unidirectional only, as explicitly stated in the Vishay Features section. It conducts surge current from cathode to anode only and must be oriented with the banded end toward the protected line. For bidirectional protection, a separate device such as TPSMB10CAHE3_A/I would be required - not the TPSMB10AHE3_A/I variant.
