Product details
Overview
SM6T7V5AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 7.13 V minimum breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 11.3 V maximum clamping voltage (VC) at 53.0 A peak pulse current, and 600 W peak pulse power rating per 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial control systems.
For engineers reviewing the SM6T7V5AHE3_A/I datasheet, SM6T7V5AHE3_A/I pinout, SM6T7V5AHE3_A/I application, or SM6T7V5AHE3_A/I equivalent, key selection criteria include clamping performance under 53 A surge, AEC-Q101 qualification status, unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped overvoltage protection device, triggered when reverse voltage exceeds 7.13 V (VBR min) and clamping to ≤11.3 V at 53.0 A (10/1000 μs). Its glass-passivated junction ensures stable leakage (<500 μA at 6.40 V) and low inductance for fast transient response.
Rated for -65 °C to +150 °C junction temperature, it delivers 600 W peak pulse power with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), and meets MSL Level 1 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 7.13 V - Ensures reliable triggering above circuit's 6.40 V operating rail without false conduction |
| VWM | 6.40 V - Maximum continuous reverse voltage before leakage exceeds 500 μA |
| VC @ IPPM | 11.3 V at 53.0 A - Clamps transient energy to safe level for downstream 5 V or 3.3 V logic interfaces |
| PPPM | 600 W - Withstands 10/1000 μs surges common in automotive load-dump and inductive kick events |
| IFSM | 100 A - Supports single half-sine 10 ms surge, critical for motor driver and relay coil protection |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and high-power industrial enclosures |
| Package | SMB (DO-214AA) - Standardized 2-pin SMT outline with 0.220" body length, compatible with IPC-7351B footprint |
Pinout & Package
SMB (DO-214AA) surface-mount package with matte tin-plated leads, 0.220" × 0.130" body, and cathode band marking on one end. Mounting requires 0.2" × 0.2" copper pads per terminal per Vishay recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; tied to system ground in typical unidirectional TVS configuration | Connected to GND plane to provide low-impedance path for surge current return |
| Cathode | Protected line connection; marked by band; reverse-biased during normal operation | Connected to signal/power line being protected (e.g., CAN_H, 12 V rail, sensor output) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
| 600 W peak pulse power | Handles ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump) waveforms without degradation |
| Glass passivated junction | Ensures stable VBR tolerance (±5%) and <500 μA leakage at VWM, critical for low-power sensor nodes |
| Low inductance design | Minimizes voltage overshoot during fast transients (e.g., EFT bursts), improving clamping fidelity |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients up to 35 V and 100 ms duration. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between power rail and ground, activated within nanoseconds of overvoltage onset. Use Value: Limits rail voltage to ≤11.3 V during 53 A surge, preventing damage to 16 V-rated DC-DC converters and microcontrollers. |
Use Scenario: Shielding analog outputs of pressure/temperature sensors in PLC modules from EFT and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS connected across differential signal pair (e.g., 4–20 mA loop) to suppress sub-100 ns spikes. Use Value: Maintains signal integrity with <500 μA leakage at 6.4 V, avoiding offset errors in precision 16-bit ADC front-ends. |
| Consumer Device USB Port Protection | Telecom Base Station Control Interface |
Use Scenario: Safeguarding USB 2.0 data lines and VBUS in smart home hubs exposed to human-body ESD (±8 kV contact). IC Role / Device Role / Timing Role: Dual-channel TVS array replaced here by discrete SM6T7V5AHE3_A/I on VBUS line only, with separate protection for D+/D−. Use Value: Clamps ESD pulses to <12 V within 1 ns, meeting IEC 61000-4-2 Level 4 without compromising signal rise time. |
Use Scenario: Guarding RS-485 control lines in outdoor telecom cabinets subjected to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Primary coarse protection stage upstream of integrated RS-485 transceivers, absorbing bulk surge energy before secondary TVS or MOV stages. Use Value: Dissipates 600 W peak energy to prevent latch-up or permanent failure of isolated communication ICs operating at ±12 V supply. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A-E3/52 | Same SMB package, but VBR min = 7.9 V, VC = 12.0 V at 49.2 A; no AEC-Q101 qualification | Commercial-grade only; not approved for automotive under-hood use | Select when cost sensitivity outweighs automotive qualification requirements and higher clamping voltage is acceptable |
| 1.5SMC7.5A | Higher-power SMC package (2.5 mm × 4.5 mm vs. SMB's 2.2 mm × 3.9 mm); VBR min = 7.1 V, VC = 12.5 V at 48.0 A | Larger footprint and 1500 W rating - over-engineered for PCB space-constrained designs needing only 600 W | Choose only if board layout allows larger SMC and higher surge margin is required beyond 600 W |
Compared with SMAJ7.5A-E3/52 and 1.5SMC7.5A, SM6T7V5AHE3_A/I offers tighter VBR tolerance, lower clamping voltage, and AEC-Q101 validation - making it optimal for space-constrained automotive and industrial applications where reliability and precise voltage limiting are critical.

FAQ
What is the clamping voltage of SM6T7V5AHE3_A/I at its rated peak pulse current?
The SM6T7V5AHE3_A/I has a maximum clamping voltage (VC) of 11.3 V at 53.0 A peak pulse current, measured using the standardized 10/1000 μs waveform. This value ensures protected circuits remain below critical voltage thresholds during surge events. The SM6T7V5AHE3_A/I achieves this performance with low dynamic impedance and glass-passivated junction stability across temperature.
Is SM6T7V5AHE3_A/I qualified for automotive applications?
Yes, SM6T7V5AHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification per JESD47. This makes SM6T7V5AHE3_A/I suitable for under-hood and chassis-mounted automotive electronics where reliability under thermal and mechanical stress is essential.
What does the "A/I" suffix mean in SM6T7V5AHE3_A/I?
The "A/I" suffix in SM6T7V5AHE3_A/I denotes packaging and reel configuration: "A" indicates revision code A per Vishay's internal documentation, and "I" specifies 13-inch diameter plastic tape and reel with 3200 units per reel. This matches the ordering format defined in Vishay's SM6T datasheet revision 09-Jan-2024, Document Number 88385.
How does SM6T7V5AHE3_A/I compare to bidirectional TVS diodes like SM6T7V5CA?
SM6T7V5AHE3_A/I is unidirectional and features a cathode band for polarity identification, while SM6T7V5CA is bidirectional with no polarity marking. The unidirectional SM6T7V5AHE3_A/I provides lower leakage (<500 μA at 6.40 V) and is preferred for DC rail protection. Bidirectional variants are used for AC or differential signal lines where voltage polarity reverses, such as RS-485 or audio inputs.
What is the thermal resistance of SM6T7V5AHE3_A/I, and how does it affect PCB layout?
SM6T7V5AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe junction temperatures, Vishay specifies mounting on 0.2" × 0.2" copper pads per terminal. Reducing RθJA via additional thermal vias or copper pour directly improves surge endurance and long-term reliability under repetitive transient conditions.
