Product details
Overview
SMC3K60CAHM3/57 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 66.7–73.7 V at 1 mA, stand-off voltage 60 V, and clamping voltage 96.8 V at 31.0 A peak surge current. It protects automotive-grade sensor signal lines and MOSFET gate drivers against inductive switching transients.
For engineers reviewing the SMC3K60CAHM3/57 datasheet, SMC3K60CAHM3/57 pinout, SMC3K60CAHM3/57 application, or SMC3K60CAHM3/57 equivalent, key selection criteria include AEC-Q101 qualification, bidirectional polarity, 96.8 V clamping at 31.0 A, MSL level 1 compliance, and halogen-free RoHS-compliant construction with matte tin-plated leads.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transient overvoltage events, leveraging avalanche breakdown to shunt surge current away from protected circuitry. Its low incremental surge resistance ensures minimal voltage overshoot under high-current pulses, while fast response time (<1 ns) enables protection of sensitive CMOS inputs and analog sensor interfaces.
The SMC3K60CAHM3/57 is designed for unidirectional PCB mounting only - not recommended for bottom-side wave soldering - and features junction temperature range from –55 °C to +150 °C, enabling use in under-hood automotive environments. Its UL 497B recognition (E136766) confirms suitability for primary-side surge protection in safety-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 3000 W - sustains high-energy transients without failure in automotive load-dump or ISO 7637-2 pulse 5a scenarios |
| Breakdown Voltage VBR | 66.7–73.7 V at 1 mA - defines minimum voltage at which avalanche conduction begins; ensures reliable triggering above system operating voltage |
| Stand-off Voltage VWM | 60 V - maximum continuous reverse working voltage; must exceed normal signal or bus voltage to prevent leakage or false triggering |
| Clamping Voltage VC | 96.8 V at 31.0 A - maximum voltage seen by protected circuit during full-rated surge; determines required IC overvoltage margin |
| Junction Temperature Range | –55 °C to +150 °C - supports operation in engine control units, battery management systems, and industrial motor drives |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT, confirming reliability in harsh environments |

Use Value: Low clamping voltage (96.8 V) prevents overvoltage stress on 12 V or 5 V buck converters feeding PHY ICs, maintaining IEEE 802.3af/at compliance. |
Use Scenario: Input-stage transient protection in universal-input AC/DC adapters for smart home hubs and IoT gateways subjected to mains-borne surges. IC Role / Device Role / Timing Role: Mounted across bulk capacitor terminals to clamp rectified line transients before they propagate into primary-side controller ICs. Use Value: Halogen-free, RoHS-compliant construction meets global environmental regulations; AEC-Q101 grade provides margin beyond consumer-grade reliability expectations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMC3K60CAHM3_A/57 | Same electrical specs and AEC-Q101 qualification; updated suffix denotes revised internal manufacturing flow and traceability controls | No functional difference; fully interchangeable in existing designs; preferred for new builds due to enhanced process consistency | Select SMC3K60CAHM3_A/57 for new designs requiring latest revision; SMC3K60CAHM3/57 remains valid for legacy BOM continuity |
| SMAJ60A-HF | Lower peak pulse power (400 W), smaller SMA package (DO-214AC), unidirectional only, no AEC-Q101 qualification | Suitable for cost-sensitive consumer electronics but not automotive or industrial environments requiring 3000 W immunity | Choose SMAJ60A-HF only for non-automotive applications with lower surge energy requirements and space-constrained layouts |

FAQ
What does the "HM3" suffix mean in SMC3K60CAHM3/57?
The "HM3" suffix in SMC3K60CAHM3/57 indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD 201 class 2 whisker resistance. It distinguishes this automotive-grade variant from commercial "M3" versions lacking AEC-Q101 validation. The SMC3K60CAHM3/57 meets all requirements for under-hood and chassis-mounted electronics.
Is SMC3K60CAHM3/57 suitable for bidirectional signal line protection?
Yes, SMC3K60CAHM3/57 is explicitly specified for bidirectional polarity only, making it ideal for protecting differential buses like CAN, RS-485, or LVDS where transients can occur with either polarity. Its symmetrical VBR and clamping behavior ensure equal protection in both directions without external circuitry.
What is the maximum clamping voltage of SMC3K60CAHM3/57 under full-rated surge current?
The maximum clamping voltage of SMC3K60CAHM3/57 is 96.8 V at 31.0 A peak pulse current (10/1000 μs waveform). This value is measured and guaranteed per Vishay's datasheet (Document Number: 89433), and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Does SMC3K60CAHM3/57 require derating at elevated ambient temperatures?
Yes, SMC3K60CAHM3/57 requires derating above TA = 25 °C per Figure 2 in the datasheet. At 125 °C ambient, its peak pulse power capability drops to approximately 50 % of the 3000 W rating at 25 °C. Thermal design must account for PCB copper area and airflow to maintain safe junction temperature below 150 °C.
Can SMC3K60CAHM3/57 be used in place of older SMC3K60CA-M3/57 parts?
Yes, SMC3K60CAHM3/57 is a direct replacement for SMC3K60CA-M3/57 in all applications, adding AEC-Q101 qualification and whisker-resistant plating while retaining identical electrical parameters, package dimensions, and soldering profile.
