Product details
Overview
SM6T10A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 10 V breakdown voltage (VBR = 9.5–10.5 V at 1.0 mA), 8.55 V stand-off voltage (VWM), 14.5 V clamping voltage (VC) at 41.0 A peak pulse current, and 600 W peak pulse power rating per 10/1000 μs waveform. It protects MOSFETs and ICs against inductive switching transients in automotive power supplies.
For engineers reviewing the SM6T10A-E3/52 datasheet, SM6T10A-E3/52 pinout, SM6T10A-E3/52 application, or SM6T10A-E3/52 equivalent, key selection criteria include unidirectional polarity, SMB package thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification eligibility (via HE3 suffix), 150 °C max junction temperature, and 100 A IFSM surge rating for robust front-end protection.
Technical Context
The SM6T10A-E3/52 operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to achieve fast response (<1 ns) to transient overvoltages. Its electrical behavior is defined by precise VBR tolerance (±5%), low leakage (<10 μA at VWM), and stable clamping under repetitive 10/1000 μs pulses up to 600 W.
Designed for PCB-level surge immunity, it relies on low-inductance SMB packaging and matte tin-plated leads compliant with J-STD-002 solderability standards. Thermal performance is validated on 0.2" × 0.2" copper pads, with derating applied above 25 °C ambient per Figure 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.50 V / 10.5 V at 1.0 mA - defines reliable turn-on threshold for transient clamping |
| VWM | 8.55 V - maximum continuous reverse voltage before leakage exceeds 10 μA |
| VC @ IPPM | 14.5 V at 41.0 A - limits protected circuit voltage during 600 W transient events |
| PPPM | 600 W (10/1000 μs) - peak surge energy handling capacity for automotive load-dump immunity |
| IFSM | 100 A (10 ms half-sine) - withstands high-current inrush without degradation |
| TJ max | +150 °C - enables operation in under-hood automotive environments |
| RθJA | 100 °C/W - thermal resistance from junction to ambient on standard PCB pad layout |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Suppressing load-dump transients (up to 35 V, 100 ms) on 12 V battery-fed ECUs in passenger vehicles. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC input, clamping within 1 ns to limit downstream voltage to ≤14.5 V. Use Value: Prevents damage to buck converter ICs rated for 16 V absolute maximum input, enabling compliance with ISO 16750-2. | Use Scenario: Protecting analog sensor outputs (e.g., 4–20 mA loop transmitters) from ESD and cable discharge events in factory automation. IC Role / Device Role / Timing Role: TVS connected across signal and ground lines, absorbing ±8 kV contact ESD per IEC 61000-4-2 with <100 ps response. Use Value: Maintains signal integrity below 10 μA leakage at 8.55 V, avoiding offset errors in precision 24-bit ADC front-ends. |
| Consumer Power Adapter Input Stage | Telecom Line Card Surge Protection |
Use Scenario: Safeguarding AC-DC adapter primary-side controllers against lightning-induced surges coupled via mains input. IC Role / Device Role / Timing Role: Mounted across bridge rectifier output, clamping 600 W transients before they reach PWM controller VCC pin. Use Value: Withstands 100 A non-repetitive surge (IFSM), eliminating need for redundant fusing in cost-sensitive adapters. | Use Scenario: Front-end protection of Ethernet PHY interfaces exposed to induced surges on outdoor cabling in telecom base stations. IC Role / Device Role / Timing Role: Paired with common-mode chokes, SM6T10A-E3/52 handles differential-mode surges on individual twisted pairs. Use Value: 14.5 V clamping ensures PHY transceivers (e.g., DP83867IR) remain within 16.5 V ABS MAX rating during 10/1000 μs threats. |
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, but 400 W PPPM, higher VC = 16.0 V at 25.0 A | Limited to lower-energy transients; not suitable for ISO 7637-2 Pulse 5a validation | Select SMAJ10A only when board space constraints prevent larger packages and surge energy is <400 W |
| 1.5SMC10A | Higher-power SMC package (1500 W), same VBR/VWM, VC = 15.0 V at 100 A | Requires larger PCB footprint; better for sustained surge duty cycles | Choose 1.5SMC10A when protecting high-current bus rails where thermal mass improves reliability |
Compared with SMAJ10A and 1.5SMC10A, SM6T10A-E3/52 delivers optimal balance of 600 W surge capability, SMB footprint, and 14.5 V clamping-making it preferred for space-constrained automotive modules requiring ISO-compliant protection without SMC-level board area.

FAQ
What is the clamping voltage of SM6T10A-E3/52 and how is it measured?
The SM6T10A-E3/52 has a maximum clamping voltage (VC) of 14.5 V at 41.0 A peak pulse current, tested using a standardized 10/1000 μs double-exponential waveform per Figure 1 in Vishay document 88385. This value represents the upper voltage limit imposed on the protected line during a 600 W transient event, ensuring downstream ICs remain within safe operating voltage ranges.
Is SM6T10A-E3/52 RoHS-compliant and halogen-free?
Yes, SM6T10A-E3/52 carries the "E3" suffix, indicating it is RoHS-compliant and manufactured to commercial-grade specifications per Vishay's material categorization policy. It is not halogen-free; for halogen-free compliance, the M3-suffixed variant (e.g., SM6T10A-M3/52) must be selected.
Can SM6T10A-E3/52 be used in bidirectional configurations?
No, SM6T10A-E3/52 is a unidirectional TVS diode, identified by its cathode band marking. For bidirectional operation, Vishay specifies the CA-suffixed variant (e.g., SM6T10CA), which provides symmetrical clamping in both polarities and omits the polarity band.
What is the maximum operating temperature for SM6T10A-E3/52?
The SM6T10A-E3/52 has a specified operating junction temperature range of –65 °C to +150 °C. Its thermal resistance (RθJA) is 100 °C/W on standard 0.2" × 0.2" copper pads, meaning power dissipation must be derated above 25 °C ambient to maintain TJ ≤ 150 °C per Figure 2 in the datasheet.
Does SM6T10A-E3/52 meet AEC-Q101 requirements?
The base SM6T10A-E3/52 is not AEC-Q101 qualified; however, Vishay offers automotive-grade versions under ordering codes SM6T10AHE3_B/H and SM6T10AHM3_B/H, which undergo full AEC-Q101 stress testing and are marked with HE3 (RoHS + AEC-Q101) or HM3 (halogen-free + AEC-Q101) suffixes.
