Product details
Overview
SM6T7V5A-E3/52 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 - deployed for overvoltage protection of ICs and MOSFETs in automotive sensor signal lines.
For engineers reviewing the SM6T7V5A-E3/52 datasheet, SM6T7V5A-E3/52 pinout, SM6T7V5A-E3/52 application, or SM6T7V5A-E3/52 equivalent, key selection criteria include unidirectional polarity, cathode-band marking, 100 °C/W junction-to-ambient thermal resistance, RoHS-compliant matte tin plating, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
This TVS diode operates as a clamping-type transient suppressor, leveraging an avalanche breakdown mechanism to limit voltage spikes across protected circuits. Its low-inductance SMB package and glass-passivated junction enable fast response (<1 ns) to ESD and switching transients while maintaining stable VBR tolerance (±5%) and low leakage (<500 μA at VWM).
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient, with thermal resistance RθJA = 100 °C/W on standard 0.2" × 0.2" copper pads. It supports single-pulse surge handling up to 100 A IFSM (10 ms half-sine) and meets J-STD-020 MSL Level 1 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA test current - defines precise avalanche onset range for reliable clamping threshold |
| VWM | 6.40 V - maximum continuous reverse voltage before significant leakage; ensures no conduction during normal operation |
| VC @ IPPM | 11.3 V at 53.0 A (10/1000 μs) - limits transient voltage seen by downstream circuitry to safe levels |
| PPPM | 600 W - peak transient energy absorption capability under standardized surge waveform |
| IFSM | 100 A - surge current rating for 10 ms half-sine wave, critical for inductive load switch-off protection |
| RθJA | 100 °C/W - thermal resistance determines junction temperature rise under sustained power dissipation |
| TJ max | +150 °C - maximum allowable junction temperature for long-term reliability in high-ambient environments |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case with matte tin-plated leads; cathode indicated by band marking on one end.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog output lines of engine coolant temperature sensors exposed to load-dump transients in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between sensor output and ECU input, conducting only during overvoltage events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Same SMB package; higher VWM = 7.0 V, VBR min = 7.78 V, VC = 12.0 V at 49.2 A | Slightly higher clamping voltage reduces margin for 5 V logic protection but improves noise immunity in noisy 12 V systems | Select SMBJ7.0A when tighter VWM/VBR margin is needed and 12.0 V clamping is acceptable |
| P6SMB7.0A | Same footprint; lower PPPM = 600 W (same), but VC = 12.5 V at 48 A and RθJA = 110 °C/W | Higher thermal resistance limits sustained surge duty cycle; less suitable for repetitive transients | Choose P6SMB7.0A only for cost-sensitive, low-duty-cycle applications where thermal budget allows |
Compared with SM6T7V5A-E3/52, SMBJ7.0A offers higher standoff and slightly looser clamping, while P6SMB7.0A trades thermal performance for legacy compatibility - SM6T7V5A-E3/52 delivers optimal balance of low VC, tight VBR tolerance, and MSL-1 process readiness.

FAQ
What is the polarity configuration of SM6T7V5A-E3/52?
The SM6T7V5A-E3/52 is a unidirectional Transient Voltage Suppressor. Its cathode is marked by a band on the SMB package body, and it conducts only when the cathode is biased positive relative to the anode - making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants (e.g., SM6T7V5CA) that protect AC or floating signals.
Does SM6T7V5A-E3/52 meet automotive qualification standards?
The base SM6T7V5A-E3/52 is RoHS-compliant and commercial-grade; however, Vishay offers AEC-Q101 qualified versions under ordering codes SM6T7V5AHE3_X (RoHS + AEC-Q101) and SM6T7V5AHM3_X (halogen-free + AEC-Q101). These variants undergo stress testing per AEC-Q101 Rev D and are intended for under-hood and safety-critical automotive use.
What is the maximum clamping voltage of SM6T7V5A-E3/52 under standard test conditions?
The SM6T7V5A-E3/52 has a maximum clamping voltage (VC) of 11.3 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 53.0 A. This value is measured per Figure 1 in Vishay document 88385 and defines the upper voltage limit imposed on protected circuitry during surge events.
Can SM6T7V5A-E3/52 be used in bidirectional signal protection?
No - SM6T7V5A-E3/52 is strictly unidirectional and must not be used on AC or polarity-agnostic lines. For bidirectional protection, Vishay specifies the SM6T7V5CA variant (with "CA" suffix), which features symmetrical breakdown in both directions and no polarity marking. Using SM6T7V5A-E3/52 in bidirectional roles risks permanent conduction or failure.
What is the thermal resistance and recommended pad layout for SM6T7V5A-E3/52?
SM6T7V5A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay document 88385. Deviation from this pad size increases thermal resistance and may cause premature thermal runaway during repeated surges.
