Product details
Overview
SM6T6V8A-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 6.45 V minimum breakdown voltage (VBR), 5.80 V stand-off voltage (VWM), 10.5 V maximum clamping voltage (VC) at 57 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor signal lines, industrial I/O interfaces, and MOSFET gate protection.
For engineers reviewing the SM6T6V8A-E3/52 datasheet, SM6T6V8A-E3/52 pinout, SM6T6V8A-E3/52 application, or SM6T6V8A-E3/52 equivalent, key selection criteria include clamping performance under 10/1000 μs transients, unidirectional polarity with cathode band marking, SMB (DO-214AA) package compatibility with automated SMT placement, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
The SM6T6V8A-E3/52 operates as a unidirectional avalanche diode with glass-passivated junction, delivering precise voltage clamping during ESD and inductive switching events. Its low-inductance SMB package and 100 °C/W junction-to-ambient thermal resistance support reliable operation up to +150 °C junction temperature under pulsed stress.
It meets J-STD-020 MSL Level 1 moisture sensitivity and is rated for 100 A non-repetitive forward surge current (IFSM). The device exhibits 1000 μA maximum reverse leakage at VWM = 5.80 V and maintains stable clamping across temperature due to a temperature coefficient αT of 5.7 × 10−4/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA test current - defines precise avalanche initiation threshold for repeatable clamping onset |
| VWM | 5.80 V - maximum continuous reverse operating voltage before leakage exceeds 1000 μA |
| VC @ IPPM | 10.5 V at 57.0 A (10/1000 μs) - limits protected circuit voltage during worst-case transient |
| PPPM | 600 W - peak pulse power handling capacity under standardized lightning/surge waveform |
| IFSM | 100 A - withstands single half-sine surge without degradation, critical for relay/coil suppression |
| TJ max. | +150 °C - enables use in under-hood automotive and high-temperature industrial environments |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant, MSL Level 1, 260 °C reflow peak.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts during overvoltage to shunt energy to ground |
| Anode | Reference node | Typically tied to system ground or low-impedance return path for clamping action |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without failure in properly laid out PCBs |
| Glass passivated junction | Ensures long-term stability and low parameter drift under thermal cycling and humidity stress |
| Low inductance SMB package | Minimizes voltage overshoot during fast transients (e.g., ESD > 1 ns rise time) |
| AEC-Q101 qualification path | HE3/M3 suffix variants available for automotive applications requiring qualified components |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and consumer enclosures |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp transients before they reach IC input pins. Use Value: Limits voltage to ≤10.5 V during 57 A surge, preventing latch-up or oxide damage in 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding digital input modules against field-wiring induced surges and relay contact bounce in factory automation systems. IC Role / Device Role / Timing Role: Front-end transient suppressor on 24 V DC input channels, coordinated with series impedance and filtering. Use Value: Withstands 100 A surge per IEC 61000-4-4, enabling compliance with industrial immunity standards without derating. |
| MOSFET Gate Protection | Consumer Power Adapter Surge Suppression |
Use Scenario: Clamping gate-source voltage spikes caused by transformer leakage in flyback or half-bridge SMPS designs. IC Role / Device Role / Timing Role: Fast-response unidirectional clamp connected directly across MOSFET gate and source terminals. Use Value: 10.5 V clamping ensures gate oxide remains below absolute maximum rating even during 100 ns dv/dt events. |
Use Scenario: Secondary-side transient suppression in AC/DC adapters exposed to mains-borne surges and ESD during plug insertion. IC Role / Device Role / Timing Role: Standoff-rated TVS on 5 V/12 V output rails to protect USB ports and downstream PMICs. Use Value: 5.80 V VWM allows normal regulation while clamping to 10.5 V - sufficient margin above 5 V rail with tolerance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | Lower VBR (6.0–6.67 V), same SMB package, 400 W PPPM | Less robust for high-energy transients; suitable only where 400 W suffices | Select when cost sensitivity outweighs need for full 600 W surge margin |
| 1.5SMC6.8A | Same VBR range, higher VC (10.8 V), 1500 W PPPM, larger SMC package | Requires PCB layout change; used where higher surge immunity is mandatory | Choose for mission-critical industrial equipment needing >600 W headroom and proven field reliability |
Compared with SMAJ6.0A and 1.5SMC6.8A, the SM6T6V8A-E3/52 delivers optimal balance of 600 W surge capability, SMB footprint, and tight 6.45–7.14 V breakdown tolerance - making it preferred for space-constrained automotive and industrial designs requiring validated AEC-Q101 path and J-STD-020 compliance.

FAQ
What is the clamping voltage of SM6T6V8A-E3/52 under standard surge conditions?
The SM6T6V8A-E3/52 has a maximum clamping voltage (VC) of 10.5 V at 57.0 A peak pulse current with a 10/1000 μs waveform. This value is measured per JEDEC standards and ensures protected circuits remain within safe voltage limits during common surge events such as inductive switching or ESD. The SM6T6V8A-E3/52 achieves this with minimal overshoot due to its low-inductance SMB package.
Is SM6T6V8A-E3/52 suitable for automotive applications?
Yes - while the SM6T6V8A-E3/52 itself is commercial-grade (E3 suffix), it belongs to the AEC-Q101-qualified SM6T family. Automotive-grade versions use HE3 or HM3 suffixes (e.g., SM6T6V8AHE3_A). The SM6T6V8A-E3/52 shares identical electrical characteristics and SMB packaging, making it ideal for prototyping and non-automotive-qualified systems where the same robustness is needed without formal qualification documentation.
What does the "-E3/52" suffix indicate in SM6T6V8A-E3/52?
The "-E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/52" specifies packaging in 7-inch plastic tape-and-reel format with 750 units per reel. This configuration supports automated SMT assembly and complies with J-STD-002 solderability and JESD22-B102 whisker resistance standards. The SM6T6V8A-E3/52 is optimized for high-volume manufacturing environments.
How does SM6T6V8A-E3/52 compare to bidirectional TVS diodes like SM6T6V8CA?
The SM6T6V8A-E3/52 is unidirectional and intended for DC-line protection where polarity is fixed (e.g., VCC-to-ground), offering tighter VBR tolerance and lower leakage. In contrast, SM6T6V8CA is bidirectional, suited for AC or differential signal lines (e.g., RS-485), but exhibits doubled leakage at low VWM. For single-polarity rails, the SM6T6V8A-E3/52 provides superior standoff integrity and lower standby power loss.
What thermal considerations apply to SM6T6V8A-E3/52 in continuous operation?
The SM6T6V8A-E3/52 has a typical RθJA of 100 °C/W and maximum power dissipation (PD) of 5.0 W on infinite heatsink at TA = 50 °C. In real-world PCB layouts with 0.2" × 0.2" copper pads per terminal, derating is required above 25 °C ambient. Continuous DC leakage must stay below 1000 μA at 5.80 V to avoid thermal runaway - verified by the SM6T6V8A-E3/52's specified TJ max. of +150 °C.
