Product details
Overview
SMC5K13CA-M3/H from Vishay General Semiconductor is a bidirectional 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), 13 V stand-off voltage (VWM), and 21.5 V maximum clamping voltage (VC) at 233 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMC5K13CA-M3/H datasheet, SMC5K13CA-M3/H pinout, SMC5K13CA-M3/H application, or SMC5K13CA-M3/H equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT assembly using matte tin-plated leads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector triggered by transient overvoltage events. Its bidirectional structure enables symmetrical clamping above ±14.4 V breakdown (VBR min), with fast response time and low dynamic impedance ensuring effective suppression of 8/20 μs lightning surges up to 40 kW and 10/1000 μs switching transients.
Thermal performance is defined by RthJA = 90 °C/W (JEDEC 51-2A, FR4, 2 oz Cu) and RthJM = 4.0 °C/W (JEDEC 51-14 TDIM), supporting reliable operation up to TJ = 175 °C. The device meets MSL Level 1 and passes JESD201 Class 2 whisker testing, confirming robustness for reflow soldering at 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum reverse working voltage before clamping begins; defines safe operating margin for 12 V nominal systems. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Ensures consistent turn-on across production lots; guarantees clamping activation above system operating voltage. |
| VC @ IPPM | 21.5 V at 233 A (10/1000 μs) - Limits protected circuit voltage during worst-case surge; keeps downstream components below absolute maximum ratings. |
| PPPM | 5000 W (10/1000 μs) - Sustains high-energy transients common in automotive load-dump and industrial motor switching. |
| TJ max | +175 °C - Enables use in under-hood automotive environments and high-temperature industrial enclosures without derating. |
| ESD immunity | ±30 kV HBM (contact/air) per IEC 61000-4-2 - Provides robust electrostatic discharge protection for exposed connectors and sensor interfaces. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, industrial-grade (M3 suffix). Case molded to UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Surge current return path | Bidirectional construction eliminates polarity marking; either terminal serves as anode or cathode depending on transient polarity. |
| Anode (Cathode) | Surge current injection node | Terminal symmetry allows flexible PCB layout; no orientation constraints during placement or routing. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without external polarity management. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, body control, and ADAS modules subject to extended temperature cycling and vibration stress. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for sensitive gate drivers and microcontrollers. |
| MSL Level 1 rating | Supports standard reflow profiles up to 260 °C peak without moisture-induced popcorn failure or delamination. |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V power rails feeding ECUs, lighting modules, and window lift controllers against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed at power entry point to clamp voltage spikes before they reach downstream regulators and logic ICs. Use Value: Maintains rail integrity below 22 V during 5000 W surges, preventing brownout resets and latch-up in automotive microcontrollers. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA, 0–10 V) from ESD and field-wiring transients in factory automation sensors. IC Role / Device Role / Timing Role: Bidirectional voltage clamp on differential or single-ended signal paths, placed adjacent to connector pins. Use Value: Limits transient-induced offset errors and prevents op-amp saturation, preserving measurement accuracy during EMC testing. |

IC Role / Device Role / Timing Role: Clamp positioned across half-bridge supply rails to absorb energy from flyback diodes and parasitic inductance. Use Value: Reduces MOSFET avalanche stress by limiting VDS excursion to ≤22 V, extending device lifetime and reducing thermal derating needs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA-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 with lower surge exposure; not rated for AEC-Q101 or 40 kW events | Select when board area is critical and surge threat level is limited to IEC 61000-4-5 Level 3 (0.5 kV/1.0 kV). |
| 1.5KE13CA (ON Semiconductor) | Higher VC (24.4 V @ 205 A), through-hole DO-201 package, same 5000 W rating, non-AEC-Q101 | Used in legacy industrial power supplies where manual assembly or wave soldering is required; lacks automotive qualification | Choose for cost-sensitive, non-automotive designs requiring proven reliability but no surface-mount requirement. |
Compared with SMAJ13CA-E3/5A and 1.5KE13CA, the SMC5K13CA-M3/H delivers superior surge handling (40 kW capability), automotive-grade qualification, and optimized thermal resistance for high-reliability SMT deployment-making it the preferred choice for next-generation automotive and industrial power systems.

FAQ
What is the breakdown voltage range for SMC5K13CA-M3/H?
The SMC5K13CA-M3/H has a guaranteed breakdown voltage (VBR) range of 14.4 V to 15.9 V measured at 1 mA test current. This tight tolerance ensures predictable clamping onset across temperature and production lots, critical for protecting 12 V systems where overvoltage margins must be precisely controlled. The device maintains this specification over its full operating junction temperature range of –55 °C to +175 °C.
Is SMC5K13CA-M3/H qualified for automotive applications?
Yes, the SMC5K13CA-M3/H is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including powertrain, chassis, and body control modules. This qualification includes rigorous stress testing for temperature cycling, humidity, mechanical shock, and accelerated life testing. The "M3" suffix denotes industrial grade, while AEC-Q101 compliance is verified per the full family specification document 87024 (Revision 10-Sep-2024).
What is the maximum clamping voltage of SMC5K13CA-M3/H under a 10/1000 μs surge?
The SMC5K13CA-M3/H exhibits a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current of 233 A under the standard 10/1000 μs waveform. This value is measured per Fig. 3 in Vishay document 87024 and represents the upper limit of voltage seen by protected circuitry during worst-case transient events, enabling accurate downstream component voltage rating selection.
Does SMC5K13CA-M3/H have polarity markings on the package?
No, the SMC5K13CA-M3/H does not feature a cathode band or other polarity marking because it is a bidirectional TVS diode. Its symmetrical structure allows either terminal to serve as anode or cathode depending on the polarity of the transient event. This eliminates orientation constraints during PCB layout and automated placement, simplifying design and manufacturing for AC-coupled or floating signal paths.
What is the thermal resistance from junction to ambient for SMC5K13CA-M3/H?
The junction-to-ambient thermal resistance (RthJA) for SMC5K13CA-M3/H is 90 °C/W, measured per JEDEC 51-2A on a standard FR4 PCB with 2 oz copper. This value assumes the recommended mounting pad layout shown in the datasheet outline drawing. Effective heatsinking via thermal vias or copper pour can reduce actual operating temperature rise, especially important in high-duty-cycle surge environments.
