Product details
Overview
SMC3K58CAHM3/57 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, rated for 3000 W peak pulse power (10/1000 μs), with breakdown voltage 64.4–71.2 V, stand-off voltage 58 V, and clamping voltage 93.6 V at 32.1 A surge current. It protects automotive sensor signal lines and MOSFET gates against inductive switching transients.
For engineers reviewing the SMC3K58CAHM3/57 datasheet, SMC3K58CAHM3/57 pinout, SMC3K58CAHM3/57 application, or SMC3K58CAHM3/57 equivalent, key selection criteria include bidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, UL 497B safety recognition, and halogen-free RoHS-compliant construction.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by overvoltage events exceeding its breakdown threshold. Its low incremental surge resistance and fast response time ensure effective suppression of transient energy before downstream components are damaged.
Designed for unidirectional PCB top-side mounting only, it meets MSL level 1 per J-STD-020 and withstands lead-free reflow up to 260 °C peak. The device is not recommended for bottom-side wave soldering due to thermal stress limitations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000 W (10/1000 μs waveform - defines maximum transient energy absorption capability) |
| Breakdown Voltage VBR | 64.4–71.2 V at 1.0 mA - ensures reliable turn-on above normal operating voltage |
| Stand-off Voltage VWM | 58 V - maximum continuous reverse voltage without conduction |
| Clamping Voltage VC | 93.6 V at 32.1 A IPPM - limits voltage seen by protected circuit during surge |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive and industrial environments |
| Qualification | AEC-Q101 qualified - validated for automotive reliability and lifetime requirements |
| Safety Certification | UL 497B recognized (E136766) - approved for use in safety-critical signal line protection |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Bidirectional polarity - no marking on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Transient current return path | Both terminals function identically in bidirectional operation - symmetric clamping in either polarity |
| Anode (Cathode) | Transient current entry point | No functional distinction between terminals - device conducts equally in both directions above VBR |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional polarity | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 3000 W peak pulse power | Supports high-energy transients common in automotive load-dump and inductive switch-off events |
| AEC-Q101 qualification | Validates robustness for automotive electronics including engine control, ADAS sensors, and body modules |
| UL 497B safety recognition | Permits use in telecom and industrial interfaces requiring certified surge protection |
| MSL Level 1 rating | Allows standard SMT reflow without moisture sensitivity handling - simplifies manufacturing |
Applications
| Automotive Sensor Protection | Industrial Motor Drive I/O |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from ESD and load-switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed directly at connector or IC input pins to shunt surge current away from sensitive inputs. Use Value: Limits transient voltage to ≤93.6 V while absorbing 3000 W pulses - prevents latch-up or gate oxide damage in AEC-Q100 qualified ICs. | Use Scenario: Safeguarding PLC digital I/O channels and encoder feedback lines exposed to relay coil flyback and contact arcing. IC Role / Device Role / Timing Role: Standoff protector across isolated input/output terminals to clamp induced surges before isolation barrier or microcontroller input. Use Value: Maintains 58 V DC operating margin while clamping 10/1000 μs transients to 93.6 V - preserves signal integrity and system uptime. |
| Telecom Line Interface | Consumer Power Adapter Feedback Loop |
Use Scenario: Shielding Ethernet PHY magnetics secondary side and PoE detection circuitry from lightning-induced surges and EFT. IC Role / Device Role / Timing Role: Primary-level TVS on low-voltage data lines, coordinated with gas discharge tubes or MOVs on primary side. Use Value: UL 497B certification enables compliance with IEC 61000-4-5 Level 4 (4 kV) testing when used in series with appropriate impedance. | Use Scenario: Protecting optocoupler feedback paths and voltage sense resistors in AC/DC adapters against output overvoltage faults and transformer ringing. IC Role / Device Role / Timing Role: Fast-response clamp across secondary-side error amplifier inputs to prevent false regulation or shutdown. Use Value: 1.0 μA max leakage at 58 V ensures minimal impact on feedback accuracy; 93.6 V clamping prevents op-amp saturation during fault conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMC3K58CAHM3_A/57 | Same electrical specs; updated suffix denotes revised internal test flow and traceability - identical form, fit, and function | No change in automotive or industrial use cases; fully interchangeable in existing designs | Select when new design-in requires latest Vishay revision control and enhanced lot traceability |
| SMAJ58A | Lower 400 W rating, SMA package (smaller footprint), 64.4–71.2 V VBR range preserved but lower IPPM (12.3 A) and higher VC (93.6 V same) | Suitable for space-constrained consumer electronics where 3000 W surge immunity is not required | Choose for cost-sensitive, non-automotive applications with lower surge exposure and tighter board area budgets |
Compared with SMC3K58CAHM3/57, SMC3K58CAHM3_A/57 offers identical performance with improved process control, while SMAJ58A trades surge capacity and ruggedness for compact size and lower cost - critical for tiered protection architecture decisions.

FAQ
What is the maximum clamping voltage of the SMC3K58CAHM3/57 under full-rated surge current?
The SMC3K58CAHM3/57 has a maximum clamping voltage (VC) of 93.6 V at 32.1 A peak pulse current (IPPM), measured using the standardized 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. Designers must verify that downstream components tolerate this clamped voltage under surge conditions.
Is the SMC3K58CAHM3/57 suitable for automotive applications?
Yes, the SMC3K58CAHM3/57 is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, ADAS sensor interfaces, and body electronics. Its 150 °C maximum junction temperature, MSL Level 1 rating, and halogen-free HM3 construction meet stringent automotive manufacturing and reliability requirements. It is not recommended for bottom-side wave soldering per Vishay guidelines.
How does the SMC3K58CAHM3/57 differ from the base SMC3K58CA-M3/57 variant?
The SMC3K58CAHM3/57 differs from SMC3K58CA-M3/57 by its HM3 suffix, indicating AEC-Q101 qualification, enhanced whisker resistance (JESD 201 Class 2), and automotive-grade screening. Both share identical electrical parameters and SMC package, but only the HM3 version is approved for automotive applications. The M3 variant is commercial grade only.
What is the meaning of the "/57" suffix in SMC3K58CAHM3/57?
The "/57" suffix in SMC3K58CAHM3/57 indicates packaging in 7-inch diameter plastic tape and reel, with a base quantity of 850 units per reel. This format is optimized for automated SMT placement and aligns with industry-standard feeding equipment. The part remains electrically and mechanically identical regardless of reel size designation.
Does the SMC3K58CAHM3/57 require derating at elevated ambient temperatures?
Yes, the SMC3K58CAHM3/57 requires derating above TA = 25 °C. Peak pulse power decreases linearly with increasing junction temperature, following the derating curve in Figure 2 of the Vishay datasheet (Document Number: 89433). At 125 °C ambient, the usable PPPM drops to approximately 50 % of the 3000 W rating - designers must apply thermal modeling to ensure TJ remains ≤150 °C during surge events.
