Product details
Overview
SM6T7V5AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) 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-designed for protecting MOSFETs and ICs against inductive switching transients in automotive sensor signal lines.
For engineers reviewing the SM6T7V5AHM3_A/H datasheet, SM6T7V5AHM3_A/H pinout, SM6T7V5AHM3_A/H application, or SM6T7V5AHM3_A/H equivalent, key selection considerations include its AEC-Q101 qualification, halogen-free RoHS-compliant construction (HM3 suffix), low-inductance SMB package, and verified clamping performance under standardized surge waveforms.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to deliver fast response (<1 ns) to transient overvoltages. Its electrical behavior is defined by three critical thresholds: VWM = 6.40 V (maximum reverse stand-off), VBR = 7.13–7.88 V (breakdown at 10 mA), and VC = 11.3 V (clamping at IPPM = 53.0 A).
Thermal design relies on RθJA = 100 °C/W (junction-to-ambient, typical) and RθJL = 20 °C/W (junction-to-lead), with maximum junction temperature rated at +150 °C. It meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.40 V - Maximum DC or continuous AC reverse voltage before leakage exceeds 500 μA; sets operating margin below breakdown. |
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - Confirmed breakdown range ensures reliable turn-on during transients without premature conduction. |
| VC @ IPPM | 11.3 V at 53.0 A (10/1000 μs) - Clamping voltage limits downstream voltage stress during 600 W surge events. |
| PPPM | 600 W - Peak pulse power handling capability defines protection level against standardized lightning/surge waveforms. |
| TJ max | +150 °C - Maximum junction temperature enables use in under-hood automotive environments with sustained thermal loads. |
| Package | SMB (DO-214AA) - Surface-mount outline with 0.220" × 0.130" footprint; optimized for automated placement and high-current PCB pad layout. |
Pinout & Package
SMB (DO-214AA) package with molded plastic body, matte tin-plated leads, and cathode band marking on the anode-side end. Terminals are solderable per J-STD-002 and JESD 22-B102; polarity indicated by band (cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected circuit ground or low-side reference. | Provides return path during clamping; must be routed with low-inductance trace to minimize overshoot. |
| Cathode | Current exit terminal in forward bias; connected to protected line (e.g., sensor supply or signal). | Acts as transient sink-voltage clamping occurs between cathode and anode when VAK ≥ VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-enables use in safety-critical sensor modules. |
| Halogen-free & RoHS-compliant (HM3) | Meets JEDEC JESD201 Class 2 whisker resistance and global environmental compliance without compromising thermal or electrical performance. |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) when properly mounted on 5.0 mm × 5.0 mm copper pads. |
| Low clamping ratio (VC/VBR ≈ 1.49) | Minimizes overvoltage exposure to downstream ICs-critical for 5 V logic and automotive CAN/LIN transceivers. |
Applications
| Automotive Sensor Protection | Industrial PLC Input Protection |

IC Role / Device Role / Timing Role: Primary-level unidirectional clamp on VCC and data lines referenced to local ground plane. Use Value: Low RθJL = 20 °C/W enables rapid heat dissipation during multi-pulse events, sustaining clamping performance across burst sequences. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same SMB package, but lower PPPM = 400 W; VC = 12.0 V at 33.3 A; not AEC-Q101 qualified. | Approved for commercial/industrial use only; unsuitable for automotive under-hood deployment. | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom is unnecessary. |
| SMCJ7.0A | Larger SMC (DO-214AB) package; PPPM = 1500 W; VC = 12.0 V at 125 A; AEC-Q101 available in HE3 variant. | Requires larger PCB area and higher mounting pad thermal mass; suited for higher-energy threat environments. | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits SMC footprint. |
Compared with SMAJ7.5A and SMCJ7.0A, SM6T7V5AHM3_A/H uniquely balances AEC-Q101 compliance, 600 W surge capacity, and compact SMB packaging-making it optimal for space-constrained automotive sensor nodes where qualification and footprint are co-primary constraints.

FAQ
What is the maximum clamping voltage of the SM6T7V5AHM3_A/H under standard test conditions?
The SM6T7V5AHM3_A/H 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 JEDEC standards and confirmed in the Vishay SM6T datasheet revision 09-Jan-2024. The clamping performance remains stable across its specified operating temperature range of -65 °C to +150 °C. SM6T7V5AHM3_A/H achieves this with low dynamic impedance and minimal overshoot due to its optimized chip geometry and low-inductance SMB package.
Is SM6T7V5AHM3_A/H qualified for automotive applications?
Yes, SM6T7V5AHM3_A/H is AEC-Q101 qualified, as indicated by the "HM3" suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification per AEC-Q101 requirements. This qualification makes SM6T7V5AHM3_A/H suitable for use in engine control units, ADAS sensor interfaces, and other automotive subsystems where reliability under thermal and mechanical stress is mandatory.
What does the "HM3" suffix mean in SM6T7V5AHM3_A/H?
The "HM3" suffix in SM6T7V5AHM3_A/H specifies halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance and AEC-Q101 qualification. It distinguishes this variant from commercial-grade "E3" or "M3" versions and confirms compliance with automotive environmental and reliability standards. The "_A/H" denotes packaging configuration: 7" tape-and-reel (H) with revision code A. SM6T7V5AHM3_A/H is therefore traceable, qualified, and optimized for high-reliability production environments.
How does SM6T7V5AHM3_A/H compare to bidirectional TVS diodes like SM6T7V5CA?
SM6T7V5AHM3_A/H is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., 5 V supply rails), offering tighter VWM/VBR ratios and lower leakage. In contrast, SM6T7V5CA is bidirectional and used on AC or floating signal lines (e.g., RS-485), with symmetrical clamping in both directions. SM6T7V5AHM3_A/H provides superior leakage control (<500 μA at 6.40 V) versus bidirectional variants, making it preferable for low-power sensor interfaces where standby current matters.
What PCB layout guidance applies to SM6T7V5AHM3_A/H for optimal surge performance?
For optimal surge performance, SM6T7V5AHM3_A/H must be mounted on minimum recommended copper pads: 0.2" × 0.2" (5.0 mm × 5.0 mm) per terminal, per Vishay's datasheet Figure 2 derating curve. Short, wide traces to ground and protected line reduce parasitic inductance, preserving clamping speed. Thermal vias under pads improve heat dissipation, especially critical given its RθJA = 100 °C/W. SM6T7V5AHM3_A/H should be placed as close as possible to the protected connector or IC pin to minimize loop inductance.
