Product details
Overview
SM6T7V5CA-M3/52 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), 11.3 V maximum clamping voltage (VC) at 53.0 A peak pulse current, 600 W peak pulse power (10/1000 μs), and operates across –65 °C to +150 °C junction temperature range. It is used to protect automotive sensor interfaces and industrial I/O lines against ESD and inductive switching surges.
For engineers reviewing the SM6T7V5CA-M3/52 datasheet, SM6T7V5CA-M3/52 pinout, SM6T7V5CA-M3/52 application, or SM6T7V5CA-M3/52 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.59), halogen-free RoHS-compliant construction, AEC-Q101 qualification eligibility via HM3 suffix, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
The SM6T7V5CA-M3/52 implements a silicon avalanche diode structure optimized for fast response (<1 ns) to transient overvoltages. Its bidirectional configuration enables symmetric clamping in AC-coupled or floating signal paths without polarity constraints.
It delivers 600 W peak pulse power handling per the standardized 10/1000 μs waveform, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation under repetitive surge conditions when mounted per recommended pad layout.

FAQ
What is the clamping voltage of the SM6T7V5CA-M3/52 under a 600 W transient?
The SM6T7V5CA-M3/52 has a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current of 53.0 A - corresponding to a 600 W transient per the 10/1000 μs waveform. This value is measured with the device mounted on 0.2" × 0.2" copper pads per JEDEC standards, ensuring realistic system-level performance representation for the SM6T7V5CA-M3/52.
Is the SM6T7V5CA-M3/52 suitable for automotive applications?
Yes, the SM6T7V5CA-M3/52 is halogen-free and RoHS-compliant (M3 suffix), and belongs to the AEC-Q101-qualified SM6T family. While the base M3 version is commercial grade, ordering codes ending in HM3 (e.g., SM6T7V5CAHM3_X) denote full AEC-Q101 qualification. The SM6T7V5CA-M3/52 shares identical electrical and thermal characteristics with qualified variants, making it suitable for automotive design-in pending final qualification confirmation per application requirements.
How does the bidirectional configuration of the SM6T7V5CA-M3/52 affect its PCB layout?
The SM6T7V5CA-M3/52 has no polarity marking - its bidirectional symmetry eliminates orientation constraints during placement. Layout requires only two equal-length traces to the protected line and return/ground, with recommended 0.2" × 0.2" copper pads per terminal to maintain specified thermal and surge performance. No silkscreen polarity indicator is needed, simplifying pick-and-place programming and reducing assembly errors for the SM6T7V5CA-M3/52.
What is the maximum reverse leakage current for the SM6T7V5CA-M3/52 at its stand-off voltage?
At the specified stand-off voltage (VWM) of 6.40 V, the SM6T7V5CA-M3/52 exhibits a maximum reverse leakage current (ID) of 500 μA at 25 °C. This low leakage ensures minimal power loss in always-on circuits and avoids false triggering in high-impedance sensor interfaces, directly supporting stable operation of precision analog front-ends protected by the SM6T7V5CA-M3/52.
Can the SM6T7V5CA-M3/52 replace unidirectional TVS diodes in existing designs?
No - the SM6T7V5CA-M3/52 is strictly bidirectional and cannot substitute for unidirectional TVS diodes (e.g., SM6T7V5A) in DC-biased applications where forward conduction must be blocked. Attempting replacement may cause unintended conduction during normal operation. For DC rails, use the unidirectional SM6T7V5A variant; the SM6T7V5CA-M3/52 is intended only for AC, floating, or dual-rail signal paths requiring symmetrical clamping.
