Product details
Overview
SMC5K60CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 60 V stand-off voltage (VWM), and 96.8 V maximum clamping voltage at 51.7 A IPPM - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the SMC5K60CA-M3/H datasheet, SMC5K60CA-M3/H pinout, SMC5K60CA-M3/H application, or SMC5K60CA-M3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 175 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT assembly per J-STD-002.
Technical Context
This TVS operates as a voltage-clamped shunt protector triggered by transient overvoltage events exceeding its reverse stand-off voltage of 60 V. Its bidirectional architecture enables symmetrical clamping on both polarities without polarity marking, supporting AC-coupled or floating signal lines.
The device delivers 5000 W peak pulse power under 10/1000 μs waveform and sustains 125 A peak pulse current under 8/20 μs waveform, with thermal resistance RthJA = 90 °C/W and RthJM = 4.0 °C/W - enabling robust thermal performance in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping initiates; defines safe operating margin for 48 V automotive or 54 V industrial bus systems. |
| VBR min/max | 66.7 V / 73.7 V at 1.0 mA IT - breakdown threshold range ensures reliable turn-on while avoiding false triggering during normal transients. |
| VC @ IPPM | 96.8 V at 51.7 A (10/1000 μs) - clamping voltage limits downstream IC stress to safe levels during surge events. |
| PPPM | 5000 W (10/1000 μs) - energy-handling capacity sufficient for ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4 surges. |
| TJ max | +175 °C - extended junction temperature rating supports under-hood automotive and high-ambient industrial environments. |
| ESD Rating | ±30 kV HBM (contact & air) - exceeds IEC 61000-4-2 requirements for system-level ESD immunity. |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no cathode band; matte tin-plated leads, halogen-free, RoHS-compliant, MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Transient current return path | Bidirectional terminals - either end serves as current sink during positive or negative transients; no polarity marking required. |
| Anode (Cathode) | Transient current return path | Identical function to opposite terminal; symmetric layout simplifies PCB routing and eliminates orientation dependency. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses, or ungrounded interfaces without polarity constraints. |
| 5000 W peak pulse power (10/1000 μs) | Supports high-energy transients from inductive switching (e.g., solenoid drivers) and lightning-induced surges in industrial control cabinets. |
| AEC-Q101 qualification | Validates long-term reliability under automotive thermal cycling (-55 °C to +175 °C), vibration, and humidity bias stress conditions. |
| Low clamping ratio (VC/VWM = 1.61) | Minimizes overvoltage exposure to protected ICs - critical for safeguarding 65 V-rated MOSFETs or 75 V input LDOs. |
| UL 497B recognition (E136766) | Confirms compliance with safety standards for telecom and industrial signal-line protection applications requiring certified components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA-E3/5A (Vishay) | Lower PPPM (400 W), SMA package (smaller footprint), same VWM and bidirectional structure. | Suitable for space-constrained consumer electronics but insufficient for automotive load dump or industrial 4 kV surges. | Select SMC5K60CA-M3/H when ≥5000 W surge handling and AEC-Q101 qualification are mandatory. |
| 1.5KE60CA (ON Semiconductor) | Higher VBR (66.7–73.7 V), same VWM, through-hole DO-201 package, 5000 W rating, not AEC-Q101 qualified. | Acceptable for industrial bench equipment but unsuitable for automated SMT production or automotive under-hood use. | Choose SMC5K60CA-M3/H for surface-mount manufacturability, MSL Level 1 reflow compatibility, and automotive qualification. |
Compared with SMAJ60CA-E3/5A and 1.5KE60CA, the SMC5K60CA-M3/H uniquely combines 5000 W surge capability, AEC-Q101 qualification, SMC package for high-current SMT reliability, and UL 497B safety recognition - making it the only option qualified for automotive power distribution and industrial 4 kV surge immunity in a single component.
