Product details
Overview
SM6T7V5CAHM3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 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 capability with 10/1000 μs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SM6T7V5CAHM3_A/H datasheet, SM6T7V5CAHM3_A/H pinout, SM6T7V5CAHM3_A/H application, or SM6T7V5CAHM3_A/H equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, halogen-free RoHS compliance, low clamping ratio (VC/VBR ≈ 1.59), and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VWM, and VC specifications for positive and negative surges. Its glass-passivated junction ensures stable leakage (<500 μA at VWM) and robust surge handling up to 150 °C junction temperature.
The device delivers 600 W peak pulse power per 10/1000 μs waveform when mounted on 5.0 mm × 5.0 mm copper pads, and exhibits low inductance due to SMB package geometry - critical for fast transient response in automotive CAN/LIN bus protection and sensor front-end circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA test current - defines reliable conduction onset for overvoltage events |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage exceeds 500 μA |
| VC @ IPPM | 11.3 V at 53.0 A - clamped voltage during 600 W transient, limiting stress on downstream ICs |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform, per industry-standard surge test |
| TJ max. | +150 °C - enables operation in under-hood automotive environments and industrial enclosures |
| RθJA | 100 °C/W - thermal resistance from junction to ambient, measured on standard 0.2" × 0.2" copper pads |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
SMB (DO-214AA) surface-mount package with matte tin-plated leads, UL 94 V-0 molding compound, and no polarity marking (bidirectional configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges without derating on standard layouts |
| Low clamping voltage (11.3 V) | Provides tighter voltage margin for 5 V logic and microcontroller I/O rails compared to higher-VC alternatives |
| AEC-Q101 qualified + halogen-free | Meets automotive supply chain requirements for reliability and environmental compliance (HM3 suffix) |
| MSL Level 1, 260 °C reflow | Supports lead-free SMT assembly without moisture sensitivity concerns or baking requirements |
| Glass-passivated junction | Ensures stable leakage performance and long-term reliability under thermal cycling and humidity exposure |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role: Bidirectional clamping element placed between signal line and ground, absorbing energy before it reaches the protected IC. Use Value: Maintains signal integrity below 11.3 V clamp level while surviving repeated 600 W surges - critical for ASIL-B compliant modules. | Use Scenario: Shielding PLC digital input channels from field-side surge coupling caused by relay coil de-energization or lightning-induced ground potential rise. IC Role / Device Role: Primary transient suppression device across input terminals, working in parallel with upstream series impedance. Use Value: Limits transient voltage to safe levels for optocoupler or Schmitt-trigger input stages without requiring additional RC filtering. |
| Consumer Power Adapter Protection | Telecom Line Interface |
Use Scenario: Safeguarding secondary-side DC output rails of AC/DC adapters against ESD and fast transient bursts during plug insertion or cable movement. IC Role / Device Role: Low-capacitance TVS placed directly at connector entry point to shunt transients before reaching regulation circuitry. Use Value: Halogen-free construction and MSL Level 1 compatibility support high-volume automated manufacturing and green compliance mandates. | Use Scenario: Protecting Ethernet PHY or RS-485 transceiver pins from induced surges on unshielded twisted-pair cabling in building automation networks. IC Role / Device Role: Bidirectional clamping device connected between differential pair and ground, suppressing common-mode transients. Use Value: Symmetrical VBR and VC ensure equal protection for both signal polarities - essential for full-duplex communication links. |
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 | Same VWM (6.4 V), slightly higher VC (11.5 V), lower PPPM (400 W), SMA package (larger RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for automotive load dump where 600 W rating is required | Choose SM6T7V5CAHM3_A/H for higher surge margin and AEC-Q101 qualification in automotive designs |
| 1.5KE7.5CA | Same VBR range but through-hole DO-201 package, 1500 W PPPM, higher VC (12.0 V), no AEC-Q101 or MSL Level 1 rating | Not suitable for SMT production or space-constrained PCBs; lacks automotive qualification | Choose SM6T7V5CAHM3_A/H for surface-mount compatibility, reflow readiness, and automotive-grade reliability |
Compared with SMAJ7.5CA and 1.5KE7.5CA, SM6T7V5CAHM3_A/H offers superior surge robustness in compact SMB form factor, guaranteed AEC-Q101 qualification, and optimized thermal performance for high-density automotive and industrial PCBs.

FAQ
What does the "CA" suffix indicate in SM6T7V5CAHM3_A/H?
The "CA" suffix in SM6T7V5CAHM3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression for both positive and negative polarity surges. Unlike unidirectional variants (e.g., SM6T7V5A), SM6T7V5CAHM3_A/H has no polarity marking and functions identically regardless of voltage polarity applied across its terminals - essential for protecting AC-coupled or differential signal lines.
Is SM6T7V5CAHM3_A/H qualified for automotive applications?
Yes, SM6T7V5CAHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure (HM3 suffix) and documentation. It meets rigorous automotive reliability requirements including temperature cycling, highly accelerated life testing (HALT), and ESD immunity - making it suitable for engine control units, body electronics, and ADAS sensor modules where sustained operation from −65 °C to +150 °C is required.
What is the clamping voltage of SM6T7V5CAHM3_A/H under a 600 W transient?
The clamping voltage (VC) of SM6T7V5CAHM3_A/H is 11.3 V when subjected to its rated 600 W peak pulse power with a 10/1000 μs waveform, corresponding to a peak pulse current (IPPM) of 53.0 A. This value is measured per JEDEC standards on specified PCB pad layout and represents the maximum voltage seen by protected circuitry during worst-case surge conditions.
How does the HM3 suffix differ from E3 or M3 in SM6T7V5CAHM3_A/H?
The HM3 suffix in SM6T7V5CAHM3_A/H indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from E3 (RoHS-compliant commercial grade) and M3 (halogen-free RoHS-compliant commercial grade). The HM3 variant is specifically intended for automotive applications requiring both environmental compliance and certified reliability, verified per JESD22-A108 and JESD22-A110 test protocols.
What is the thermal resistance of SM6T7V5CAHM3_A/H, and how does it affect layout design?
SM6T7V5CAHM3_A/H 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. This value assumes standard SMB footprint layout; reducing pad size or omitting thermal vias increases RθJA, potentially limiting surge repetition rate or derating peak power - so PCB layout must follow Vishay's recommended pad dimensions to maintain rated 600 W performance.
