Product details
Overview
3.0C26CA-M3 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 3000 W peak pulse power (10/1000 μs), 42.1 V maximum clamping voltage at 538 A IPPM, and 26 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment against lightning and inductive switching transients.
For engineers reviewing the 3.0C26CA-M3 datasheet, 3.0C26CA-M3 pinout, 3.0C26CA-M3 application, or 3.0C26CA-M3 equivalent, key selection criteria include its bidirectional polarity, 175 °C max junction temperature, 1.0 μA reverse leakage at VWM, 30 kV ESD immunity per IEC 61000-4-2, and SMC package compatibility with automated PCB assembly.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche breakdown when transient voltage exceeds its 28.9–31.9 V breakdown range (at 1 mA), limiting downstream circuit voltage to ≤42.1 V under 10/1000 μs surges up to 538 A. Its low incremental surge resistance ensures stable clamping performance across repetitive events.
Designed for unidirectional layout integration despite bidirectional functionality, it features no polarity marking, meets MSL Level 1 per J-STD-020, and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26CA | Lower PPPM (600 W), same VWM (26 V), SMB package (smaller footprint, higher RthJA) | Not suitable for 3000 W surge events; limited to lower-energy consumer-grade interfaces | Select only where surge threat level is defined below 600 W and space constraints prohibit SMC |
| 5.0SMDJ26CA | Higher PPPM (5000 W), same VWM (26 V), larger SMD package (DO-214AC), higher VC (42.8 V) | Better suited for extreme surge environments (e.g., utility metering), but requires larger PCB area | Choose when system-level testing confirms >3000 W threat and layout allows DO-214AC footprint |
Compared with SMBJ26CA and 5.0SMDJ26CA, the 3.0C26CA-M3 delivers optimal balance of 3000 W surge handling, SMC package manufacturability, and 42.1 V clamping-making it ideal for industrial and telecom designs requiring proven reliability without over-engineering.

FAQ
What is the breakdown voltage range of the 3.0C26CA-M3?
The 3.0C26CA-M3 has a specified breakdown voltage (VBR) range of 28.9 V to 31.9 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures consistent avalanche initiation across production lots and defines the minimum voltage at which the device begins clamping transients. The 3.0C26CA-M3 maintains tight VBR tolerance to guarantee predictable protection behavior in safety-critical circuits.
Does the 3.0C26CA-M3 require polarity-aware PCB layout?
No-the 3.0C26CA-M3 is a bidirectional TVS diode with no polarity marking on the SMC package, as confirmed in the Vishay datasheet Note under Mechanical Data. Either terminal functions as anode or cathode depending on transient polarity, allowing orientation-agnostic placement. This simplifies layout, reduces assembly errors, and supports symmetric routing on differential or AC-coupled lines-key for robust 3.0C26CA-M3 deployment.
What is the maximum clamping voltage of the 3.0C26CA-M3 under a 10/1000 μs surge?
The 3.0C26CA-M3 exhibits a maximum clamping voltage (VC) of 42.1 V when subjected to its rated peak pulse current (IPPM) of 538 A under the standard 10/1000 μs waveform. This value is measured and guaranteed per the Electrical Characteristics table in Document Number 98266. Designers use this 42.1 V VC to verify margin between clamped voltage and the absolute maximum ratings of protected ICs in the 3.0C26CA-M3 application.
Is the 3.0C26CA-M3 compliant with lead-free reflow standards?
Yes-the 3.0C26CA-M3 is RoHS-compliant and rated for lead-free reflow with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL Level 1 requirements. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards, and the -M3 suffix confirms qualification to JESD 201 Class 2 whisker resistance. These attributes ensure reliable 3.0C26CA-M3 assembly in modern high-volume SMT lines.
How does the 3.0C26CA-M3 perform under repeated surge stress?
The 3.0C26CA-M3 is characterized for non-repetitive pulse operation per datasheet Note (1), meaning its 3000 W rating applies to single or infrequent transients. For repetitive surge conditions, derating is required above TA = 25 °C using the published Peak Pulse Power Derating Curve (Fig. 1). Thermal resistance values (RthJA = 90 °C/W, RthJM = 4.0 °C/W) allow calculation of safe repetition rates-critical for validating long-term 3.0C26CA-M3 reliability in cyclic industrial systems.
