Product details
Overview
SM6T7V5CA-E3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 600 W peak pulse power (10/1000 μs), 7.13–7.88 V breakdown voltage at 10 mA, 6.40 V stand-off voltage, ≤14.5 V clamping voltage at 53.0 A, and operates from –65 °C to +150 °C - used in automotive sensor interface protection.
For engineers reviewing the SM6T7V5CA-E3/52 datasheet, SM6T7V5CA-E3/52 pinout, SM6T7V5CA-E3/52 application, or SM6T7V5CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, low clamping voltage under 53 A surge, RoHS-compliant commercial-grade packaging, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to provide symmetrical clamping in both polarities without polarity marking. Its low-inductance SMB package enables fast response to transients up to 600 W, while meeting MSL Level 1 and JESD 201 Class 2 whisker resistance standards.
The device delivers stable clamping performance across –65 °C to +150 °C junction temperature, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting reliable operation in automotive and industrial environments where thermal cycling and high-energy surges occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - defines precise voltage threshold where clamping initiates in either direction |
| VWM | 6.40 V - maximum continuous reverse voltage before leakage exceeds 500 μA |
| VC @ IPPM | 14.5 V at 53.0 A (10/1000 μs) - ensures downstream ICs see no more than 14.5 V during worst-case surge |
| PPPM | 600 W - sustains high-energy transients common in automotive load-dump or inductive switching events |
| TJ range | –65 °C to +150 °C - supports under-hood automotive and industrial control applications |
| Package | SMB (DO-214AA) - surface-mount footprint compatible with standard reflow profiles and automated pick-and-place |
Pinout & Package
SM6T7V5CA-E3/52 is a bidirectional two-terminal device housed in an SMB (DO-214AA) package with unmarked terminals - no cathode/anode designation. The case is molded with UL 94 V-0 rated compound, and terminals are matte tin-plated for solderability per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Transient input/output node | Connected across protected line and ground (or differential pair); conducts equally in both directions during overvoltage |
| Terminal 2 | Transient input/output node | Second terminal of symmetrical clamp path; no polarity dependency - simplifies PCB layout for bidirectional signal lines |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal paths (e.g., CAN, RS-485, sensor bridges) without polarity concerns |
| 600 W peak pulse power | Withstands ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 surge events in automotive ECUs |
| Low clamping voltage (14.5 V @ 53 A) | Keeps protected MOSFET gate drivers or MCU I/O pins below absolute maximum ratings during surge |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking - reduces manufacturing overhead |
| RoHS-compliant E3 suffix | Meets global environmental compliance requirements for commercial-grade electronics without halogen restrictions |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine control modules exposed to load-dump transients. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between sensor output and microcontroller ADC input. Use Value: Limits transient voltage to ≤14.5 V, preventing latch-up or damage to 5 V-tolerant ADC inputs during 12 V system surges. | Use Scenario: Safeguarding differential data lines in factory automation PLCs subject to EFT and surge coupling from motor drives. IC Role / Device Role / Timing Role: Line-to-line and line-to-ground TVS on RS-485 bus nodes operating at up to 10 Mbps. Use Value: Maintains signal integrity by clamping common-mode surges without adding capacitance that degrades edge rate. |
| Consumer USB Port ESD | Power Supply Input Stage |
Use Scenario: ESD protection for USB 2.0 D+/D– lines in portable medical devices requiring IEC 61000-4-2 Level 4 compliance. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at USB connector, before series impedance. Use Value: Responds within nanoseconds to ±8 kV contact discharge, limiting voltage seen by USB transceiver to safe levels. | Use Scenario: Secondary-side transient suppression on 5 V/3.3 V DC-DC converter outputs feeding sensitive logic. IC Role / Device Role / Timing Role: Clamp device between regulated rail and ground to absorb switching noise and back-EMF spikes. Use Value: Prevents brownout resets by holding rail voltage above minimum operating threshold during 600 W transient 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 |
|---|---|---|---|
| SMAJ7.5CA | 400 W PPPM, higher VC = 15.0 V @ 38.8 A, same SMB package | Limited to lower-energy transients; not suitable for ISO 7637-2 Pulse 5a validation | Select when cost sensitivity outweighs peak power margin and clamping voltage tightness |
| 1.5SMC7.5CA | 1500 W PPPM, larger SMC (DO-214AB) package, VC = 13.4 V @ 112 A | Requires PCB area increase and different pad layout; better for high-reliability industrial mains input stages | Choose when system-level surge testing exceeds 600 W and board space permits larger footprint |
Compared with SMAJ7.5CA and 1.5SMC7.5CA, SM6T7V5CA-E3/52 offers optimal balance of compact SMB size, 600 W robustness, and low 14.5 V clamping - making it preferred for space-constrained automotive and industrial signal-line protection where both efficiency and reliability matter.

FAQ
What is the clamping voltage of SM6T7V5CA-E3/52 under a 10/1000 μs surge?
The SM6T7V5CA-E3/52 has a maximum clamping voltage (VC) of 14.5 V when subjected to a 10/1000 μs waveform at its peak pulse current of 53.0 A. This value is measured per Figure 1 in the Vishay datasheet 88385 and ensures downstream components remain within safe operating limits during standardized surge events.
Is SM6T7V5CA-E3/52 suitable for automotive applications?
Yes, SM6T7V5CA-E3/52 is qualified for automotive use when ordered with HE3 or HM3 suffixes (AEC-Q101). While the E3/52 variant is commercial-grade, its electrical specs - including 600 W peak power, –65 °C to +150 °C operating range, and MSL Level 1 - align with many non-safety-critical automotive subsystems such as cabin sensors and body control modules.
Does SM6T7V5CA-E3/52 have polarity markings?
No, SM6T7V5CA-E3/52 is a bidirectional TVS diode and carries no polarity marking on the SMB package. Unlike unidirectional variants (e.g., SM6T7V5A), it functions identically in both directions - eliminating orientation errors during automated assembly and simplifying layout for symmetric protection schemes.
What is the standoff voltage (VWM) of SM6T7V5CA-E3/52?
The standoff voltage (VWM) of SM6T7V5CA-E3/52 is 6.40 V - the maximum DC or continuous reverse working voltage the device can withstand without exceeding 500 μA leakage current. This allows reliable operation on 5 V logic rails while maintaining sufficient margin below the 7.13 V minimum breakdown threshold.
Can SM6T7V5CA-E3/52 be used in place of SM6T7V5A?
SM6T7V5CA-E3/52 cannot directly replace SM6T7V5A in unidirectional circuits because it lacks polarity and provides symmetrical conduction. However, it is functionally interchangeable in bidirectional applications like AC signal lines or differential buses - provided layout accommodates the absence of cathode marking and system design expects equal clamping in both directions.
