Product details
Overview
SMC5K60A-M3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on power and signal lines. It delivers 5000 W peak pulse power (10/1000 μs), clamps at 96.8 V under 51.7 A surge current, and operates across -55 °C to +150 °C - used in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the SMC5K60A-M3/H datasheet, SMC5K60A-M3/H pinout, SMC5K60A-M3/H application, or SMC5K60A-M3/H equivalent, key selection criteria include its 60 V standoff voltage, AEC-Q101 qualification (via HM3 suffix variants), UL 497B recognition, and MSL Level 1 moisture sensitivity rating for robust reflow compatibility.
Technical Context
This TVS diode uses silicon avalanche junction technology to provide fast response (<1 ns) clamping against ESD and lightning-induced transients. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until breakdown threshold is exceeded.
The device features low incremental surge resistance (typ. 0.4 Ω) and thermal resistance of 90 °C/W (junction-to-ambient), enabling reliable energy dissipation without thermal runaway under repetitive surge stress. It meets IEC 61000-4-2 ±30 kV contact/air discharge immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 60 V - maximum continuous reverse operating voltage before significant leakage begins; defines safe DC bias margin. |
| Breakdown Voltage (VBR) | 66.7–73.7 V at 1 mA - guaranteed avalanche initiation range; ensures predictable clamping onset. |
| Clamping Voltage (VC) | 96.8 V at 51.7 A (10/1000 μs) - peak voltage seen by protected circuit during worst-case surge; limits downstream stress. |
| Peak Pulse Power (PPPM) | 5000 W (10/1000 μs) - maximum single-pulse energy handling capability; supports IEC 61000-4-5 Level 4 compliance. |
| Junction Temperature Range | -55 °C to +150 °C - enables deployment in under-hood automotive and industrial environments with wide thermal cycling. |
| ESD Immunity | ±30 kV HBM (contact/air) - exceeds IEC 61000-4-2 requirements for system-level ESD robustness. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; tied to lower-potential side of protected line. | Connects to ground or return path in unidirectional clamp configuration; defines polarity-sensitive placement. |
| Cathode | Current exit terminal during forward conduction; marked by band; connected to protected line. | Receives transient energy from upstream source; clamps to anode when voltage exceeds VBR; determines PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables protection against severe surges per IEC 61000-4-5, including indirect lightning strikes in industrial power inputs. |
| AEC-Q101 qualified variant available (HM3 suffix) | Validates reliability for automotive applications including body control modules and infotainment power supplies. |
| UL 497B recognized (E136766) | Confirms safety compliance for telecom and industrial equipment requiring certified overvoltage protection. |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT assembly without pre-baking; reduces manufacturing complexity and cost. |
| Low incremental surge resistance (0.4 Ω typ.) | Minimizes voltage overshoot during fast-rising transients, improving protection margin for sensitive ICs like CAN transceivers. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/5A (Vishay) | Lower PPPM (400 W), SMA package (smaller footprint, higher RthJA = 110 °C/W), same VWM/VBR range. | Suitable for space-constrained consumer electronics; insufficient for industrial lightning surge standards. | Select when board area is critical and surge energy is limited to IEC 61000-4-2 only. |
| 1.5KE60A (ON Semiconductor) | Higher leakage (5 μA max at VWM), axial DO-201 package, 1500 W PPPM, non-AEC-Q101, no UL recognition. | Acceptable for cost-sensitive industrial controls but not automotive or safety-certified systems. | Choose only for legacy through-hole designs or non-safety-critical applications with lower surge exposure. |
Compared with SMAJ60A-E3/5A and 1.5KE60A, the SMC5K60A-M3/H provides 12.5× higher pulse power than the SMAJ series and 3.3× higher than the 1.5KE series, while offering AEC-Q101 qualification and UL 497B recognition - making it the only option qualified for automotive-grade surge protection in SMC form factor.

FAQ
What is the clamping voltage of the SMC5K60A-M3/H at its rated peak pulse current?
The SMC5K60A-M3/H clamps to a maximum of 96.8 V at 51.7 A peak pulse current under the standard 10/1000 μs waveform. This value is measured and guaranteed per Vishay's datasheet (Document Number: 87742), and represents the upper limit of voltage imposed on the protected circuit during surge events. Designers use this parameter to verify that downstream components remain within their absolute maximum ratings.
Is the SMC5K60A-M3/H AEC-Q101 qualified?
The SMC5K60A-M3/H itself is not AEC-Q101 qualified; qualification applies only to variants with the HM3 suffix (e.g., SMC5K60AHM3_A/H). The M3/H suffix indicates halogen-free, RoHS-compliant construction and MSL Level 1 rating, but does not imply automotive qualification. For AEC-Q101 compliance, specify the HM3 version and confirm with Vishay's official qualification reports.
What is the maximum reverse leakage current of the SMC5K60A-M3/H at its stand-off voltage?
The SMC5K60A-M3/H exhibits a maximum reverse leakage current of 1.0 μA at its 60 V stand-off voltage (VWM), tested at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes standby power loss in always-on automotive modules - a key advantage over alternatives with higher leakage specs.
Can the SMC5K60A-M3/H be used in bidirectional surge protection circuits?
No - the SMC5K60A-M3/H is strictly unidirectional. To implement bidirectional protection, two SMC5K60A-M3/H devices must be connected in series opposition (anode-to-anode or cathode-to-cathode), or a dedicated bidirectional TVS such as the SMBJ60CA should be selected. Using a single unidirectional device in reverse-biased AC applications risks permanent breakdown.
What is the thermal resistance junction-to-ambient (RthJA) for the SMC5K60A-M3/H?
The SMC5K60A-M3/H has a typical junction-to-ambient thermal resistance (RthJA) of 90 °C/W when mounted on a standard FR4 PCB per JEDEC 51-2A. This value assumes a 2 oz. copper footprint matching the recommended pad layout. Effective thermal management requires adherence to Vishay's mounting guidelines to avoid derating and ensure sustained 5000 W pulse capability.
