Product details
Overview
SMC3K64CA-M3/57 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMC (DO-214AB) package, rated for 3000 W peak pulse power (10/1000 μs), with a standoff voltage of 64 V, breakdown voltage range 71.1–78.6 V, and clamping voltage of 103 V at 29.1 A. It protects MOSFETs and sensor signal lines in automotive powertrain control modules against inductive switching transients.
For engineers reviewing the SMC3K64CA-M3/57 datasheet, SMC3K64CA-M3/57 pinout, SMC3K64CA-M3/57 application, or SMC3K64CA-M3/57 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with wave-solder-free PCB assembly processes.
Technical Context
This TVS diode operates as a voltage-clamped surge protector with low incremental surge resistance and sub-nanosecond response time, enabling effective suppression of fast-rising transients induced by relay or solenoid switching. Its bidirectional polarity supports AC-coupled signal line protection without polarity concerns.
The device is thermally rated for junction temperatures up to +150 °C and derates linearly above 25 °C ambient, maintaining 3000 W pulse capability only at TA ≤ 25 °C. It meets UL 497B safety recognition (E136766) and J-STD-020 MSL Level 1, permitting reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 3000 W - sustains single high-energy surges common in 12 V automotive load-dump events |
| Standoff Voltage (VWM) | 64 V - maximum continuous reverse voltage before conduction begins; sets operating margin below system rail |
| Breakdown Voltage (VBR) | 71.1–78.6 V at 1 mA - defines onset of avalanche clamping; tight tolerance ensures predictable turn-on |
| Clamping Voltage (VC) | 103 V at 29.1 A - limits transient voltage seen by downstream ICs during full-rated surge current |
| Operating Temperature | –55 °C to +150 °C - supports under-hood automotive environments and industrial motor drives |
| Package | SMC (DO-214AB) - industry-standard 8.0 mm × 8.0 mm copper pad footprint with matte tin leads |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
SMC3K64CA-M3/57 uses the standard SMC (DO-214AB) surface-mount package: two-terminal, bidirectional configuration with no polarity marking. The molded case meets UL 94 V-0 flammability rating; terminals are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Transient current return path | Both terminals function identically in bidirectional mode; no dedicated cathode/anode designation |
| Anode (Cathode) | Transient current entry point | Terminal symmetry enables placement flexibility on differential or AC signal lines without orientation check |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or floating signal paths without polarity-sensitive layout constraints |
| 3000 W peak pulse rating | Meets ISO 7637-2 Pulse 5a load-dump immunity requirements for 12 V vehicle systems |
| AEC-Q101 qualification | Validated for automotive use including HTGB, TC, and UHAST testing per stress test plan |
| MSL Level 1 (260 °C) | Supports single-reflow assembly without baking; eliminates moisture-related popcorning risk |
| UL 497B recognition (E136766) | Confirms compliance with telecom and industrial surge protection safety standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMC3K64CAHM3/57 | AEC-Q101 qualified variant with identical electrical specs; HM3 suffix denotes automotive qualification grade | Required for new automotive designs where AEC-Q101 compliance is mandatory per OEM specification | Select SMC3K64CAHM3/57 when automotive qualification documentation and traceability are contractually required |
| SMAJ64A | Lower 400 W peak power rating; SMA package (smaller thermal mass); unidirectional only | Suitable for lower-energy consumer electronics; not appropriate for automotive load-dump scenarios | Choose SMAJ64A only for cost-sensitive, non-automotive applications with <1 kA surge exposure |
Compared with SMC3K64CA-M3/57, the HM3 variant adds formal AEC-Q101 certification without electrical change, while SMAJ64A trades pulse robustness and bidirectionality for smaller size and lower cost-making it unsuitable for automotive or industrial surge immunity.

FAQ
What does the "-M3/57" suffix mean in SMC3K64CA-M3/57?
The "-M3" suffix indicates halogen-free, RoHS-compliant, commercial-grade construction with JESD 201 Class 2 whisker resistance; "/57" specifies packaging in 7-inch plastic tape-and-reel format containing 850 units. This configuration is optimized for automated SMT placement and meets IPC-A-610 Class 2 acceptability standards for industrial electronics.
Is SMC3K64CA-M3/57 suitable for new automotive designs?
No-Vishay explicitly marks SMC3K64CA-M3/57 as "Not for New Designs." For new automotive projects, engineers must select the AEC-Q101-qualified SMC3K64CAHM3/57 variant, which shares identical electrical parameters but includes full automotive qualification documentation and traceability required by Tier 1 suppliers.
What is the maximum clamping voltage of SMC3K64CA-M3/57 under full-rated surge current?
The maximum clamping voltage of SMC3K64CA-M3/57 is 103 V measured at 29.1 A peak pulse current using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range (–55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can SMC3K64CA-M3/57 be used in bottom-side wave soldering processes?
No-Vishay explicitly states that SMC3K64CA-M3/57 is "not recommended for PCB bottom side wave mounting." Its SMC package and internal construction are optimized for reflow soldering only; wave soldering may cause thermal stress, delamination, or premature failure due to asymmetric heating and flux entrapment.
How does SMC3K64CA-M3/57 differ from the SMAJ64A TVS diode?
SMC3K64CA-M3/57 delivers 3000 W peak pulse power in a larger SMC package with bidirectional clamping and AEC-Q101 qualification, whereas SMAJ64A offers only 400 W in an SMA package, is unidirectional, and lacks automotive qualification. Their VWM and VC values differ significantly, making them non-interchangeable in high-energy applications.
