Overview
SMA5J6.0CA-M3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 µs), 48.5 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supply rails.
For engineers reviewing the SMA5J6.0CA-M3/61 datasheet, SMA5J6.0CA-M3/61 pinout, SMA5J6.0CA-M3/61 application, or SMA5J6.0CA-M3/61 equivalent, key selection criteria include bidirectional clamping capability, 500 W surge rating with low clamping voltage, halogen-free RoHS-compliant construction (M3 suffix), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped crowbar during transient events, leveraging an avalanche junction to limit reverse voltage across protected circuitry. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity-sensitive layout constraints.
Designed for 10/1000 µs surge waveforms per ANSI/IEEE C62.35, it delivers 48.5 A peak pulse current with ≤10.3 V clamping voltage and exhibits low incremental surge resistance for minimal voltage overshoot. Thermal resistance is 80 °C/W junction-to-ambient when mounted on minimum recommended pad layout.

IC Role / Device Role / Timing Role: Voltage-clamping TVS placed upstream of LDOs and CAN transceivers to limit input surge to safe levels. Use Value: Withstands 500 W surges while clamping to ≤10.3 V, preventing latch-up or gate oxide damage in downstream 3.3 V/5 V logic. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop or 0–10 V sensor outputs) from ESD and inductive switching noise. IC Role / Device Role / Timing Role: Bidirectional transient shunt across differential or single-ended signal pairs to clamp ±kV ESD events. Use Value: Symmetrical clamping ensures protection regardless of signal polarity; low leakage (<1 μA at 6.0 V) avoids measurement drift in precision sensor interfaces. |
| Consumer USB Port ESD Protection | Telecom DSL Line Surge Suppression |
Use Scenario: Secondary-level ESD protection on USB 2.0 VBUS and data lines in portable chargers and docking stations. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing IEC 61000-4-2 ±8 kV contact discharge energy before it reaches USB controller ICs. Use Value: 6.0 V VWM allows full 5 V USB operation; fast avalanche response (<1 ns) prevents propagation of sub-nanosecond ESD pulses. |
Use Scenario: Primary surge suppression on twisted-pair DSL lines exposed to lightning-induced surges in outdoor telecom cabinets. IC Role / Device Role / Timing Role: High-energy bidirectional clamp placed at line interface to divert >100 A surges away from PHY transceivers and transformers. Use Value: 500 W rating and DO-214AC thermal mass enable reliable multi-event endurance without parameter shift or catastrophic failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0A-M3/61 | Unidirectional version; same VWM, VBR, and PPPM, but conducts only in reverse bias; includes cathode band marking. | Requires polarity-aware layout; unsuitable for AC or floating signals where bidirectional clamping is mandatory. | Select SMA5J6.0A-M3/61 only when protecting DC rails with known polarity and space-constrained unidirectional layouts. |
| SMB5J6.0CA-M3/61 | Same electrical specs but in larger SMB (DO-214AA) package; higher thermal mass yields lower RθJA (60 °C/W vs. 80 °C/W). | Better sustained surge handling in high-temperature enclosures; requires larger PCB footprint (4.58 mm × 3.94 mm vs. 4.50 mm × 2.79 mm). | Choose SMB5J6.0CA-M3/61 when thermal derating above 85 °C ambient is required and board area permits larger package. |
Compared with SMA5J6.0A-M3/61, the SMA5J6.0CA-M3/61 enables polarity-agnostic layout and simplifies BOM management for mixed-signal systems; versus SMB5J6.0CA-M3/61, it trades thermal margin for compactness-critical in space-limited automotive modules and portable electronics.

FAQ
What is the polarity configuration of SMA5J6.0CA-M3/61?
The SMA5J6.0CA-M3/61 is a bidirectional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode band or polarity marking, enabling installation without orientation concern. This design ensures identical clamping behavior for positive and negative transients, making SMA5J6.0CA-M3/61 ideal for AC-coupled, floating, or differential signal paths where polarity cannot be guaranteed.
Does SMA5J6.0CA-M3/61 meet automotive qualification standards?
The base SMA5J6.0CA-M3/61 is halogen-free and RoHS-compliant but not AEC-Q101 qualified. For automotive applications requiring AEC-Q101, Vishay offers the variant SMA5J6.0CAHM3_A/H (with HM3 suffix and revision code), which adds full AEC-Q101 qualification while retaining identical electrical specs and SMA package. Always verify the full ordering code when sourcing for automotive use.
What is the maximum clamping voltage of SMA5J6.0CA-M3/61 under surge conditions?
The SMA5J6.0CA-M3/61 clamps to a maximum of 10.3 V when subjected to its rated 48.5 A peak pulse current (IPPM), defined by the 10/1000 µs waveform. This value is measured at the device terminals under standardized test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and represents the upper bound of voltage seen by protected circuitry during a 500 W transient event.
How does the M3 suffix affect the environmental compliance of SMA5J6.0CA-M3/61?
The M3 suffix on SMA5J6.0CA-M3/61 indicates halogen-free, RoHS-compliant construction per IEC 61249-2-21 and EU Directive 2011/65/EU. It confirms absence of brominated flame retardants (BFRs), chlorinated flame retardants (CFRs), and antimony trioxide, while maintaining UL 94 V-0 flammability rating. This makes SMA5J6.0CA-M3/61 suitable for environmentally regulated markets including automotive Tier 1 supply chains.
Can SMA5J6.0CA-M3/61 be used in place of SMA5J6.0A-M3/61?
No-SMA5J6.0CA-M3/61 and SMA5J6.0A-M3/61 are not interchangeable without layout review. The "CA" denotes bidirectional operation with no polarity marking, while "A" indicates unidirectional function with cathode band identification. Substituting one for the other risks incorrect clamping behavior on AC or floating nodes, or unnecessary layout complexity in DC-only designs. Always match the suffix to system-level polarity requirements.
