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 71.3 A IPPM, and 26 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning-induced surges in industrial and telecom equipment.
For engineers reviewing the 3.0C26CA-M3 datasheet, 3.0C26CA-M3 pinout, 3.0C26CA-M3 application, or 3.0C26CA-M3 equivalent, this device delivers verified bidirectional clamping, MSL Level 1 reflow compatibility, 30 kV ESD immunity per IEC 61000-4-2, and halogen-free RoHS-compliant construction - critical for robust board-level transient suppression in high-reliability designs.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds its 28.9–31.9 V breakdown range (at 1 mA), it avalanches to limit transient energy across protected nodes. Its low incremental surge resistance ensures stable clamping under high-current 8/20 μs surges up to 538 A, while thermal resistance RthJM of 4.0 °C/W enables effective heat transfer to the PCB mount.
Designed for unidirectional or bidirectional line protection without polarity marking, the 3.0C26CA-M3 supports operation from –55 °C to +175 °C junction temperature and meets JESD201 Class 2 whisker resistance, making it suitable for automotive-adjacent industrial environments where thermal cycling and long-term reliability are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 26 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC/AC bias margin for protected circuit. |
| VBR min/max | 28.9 V / 31.9 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 42.1 V at 71.3 A (10/1000 μs) - Clamping voltage under standard surge; determines maximum stress on downstream components. |
| PPPM | 3000 W (10/1000 μs) - Peak surge energy handling capacity; validates suitability for IEC 61000-4-5 Level 3/4 compliance testing. |

Applications
| Industrial Motor Drives | Telecom Power Interfaces |
|---|---|
Use Scenario: Protection of gate drivers and feedback sensing lines in variable-frequency drives subjected to inductive kickback from 48 V–400 V motor windings. IC Role / Device Role / Timing Role: Shunt TVS placed directly across MOSFET gate-source or op-amp input pins to clamp sub-100 ns transients. Use Value: Limits gate voltage to ≤42.1 V during 71.3 A surges, preventing MOSFET destruction and ensuring drive-stage continuity. | Use Scenario: Surge suppression on -48 V DC power feeds and RS-485 data lines in central office and remote radio head equipment. IC Role / Device Role / Timing Role: Bidirectional clamping element between power rail and chassis ground or differential data pair and common-mode reference. Use Value: Maintains signal integrity under 8/20 μs lightning surges up to 538 A while preserving <1 μA leakage at nominal -48 V bias. |
| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
Use Scenario: Input protection for LIN bus transceivers and load-switch controllers exposed to battery dump and load-dump transients in 12 V systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp on supply inputs and communication pins; operates alongside upstream fuses and filters. Use Value: Survives 30 kV ESD contact discharge and clamps dump transients to ≤42.1 V, enabling ASIL-B compatible design without secondary protection. | Use Scenario: Protection of analog front-ends for pressure, temperature, and current sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF at 0 V) shunt device on 0–10 V or 4–20 mA signal paths. Use Value: Adds <1 μA leakage at 26 V bias and clamps fast transients without distorting millivolt-level sensor outputs or introducing offset error. |
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), SMC-compatible but smaller SMB package (DO-214AA). | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 testing. | Select when space-constrained layouts prioritize footprint over surge margin. |
| SMCJ26CA | Identical SMC package and 3000 W rating, but higher VBR (28.9–31.9 V same), slightly higher VC (43.3 V at 69.4 A). | Functionally interchangeable in most 26 V protection circuits; minor clamping variance within design margin. | Valid alternative if 3.0C26CA-M3 lead times are extended; verify layout compatibility with identical SMC outline. |
Compared with SMBJ26CA and SMCJ26CA, the 3.0C26CA-M3 offers identical surge rating to SMCJ26CA but with tighter VBR tolerance and lower clamping voltage - delivering superior protection margin for sensitive 26 V rail interfaces without requiring PCB redesign.

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 during overvoltage events while accommodating process variation. The value is confirmed in Vishay's official datasheet document 98266, revision 09-Jan-2024, and applies strictly to the 3.0C26CA-M3 variant.
Does the 3.0C26CA-M3 support lead-free reflow soldering?
Yes, the 3.0C26CA-M3 is qualified for lead-free reflow with a maximum peak temperature of 260 °C and meets MSL Level 1 per J-STD-020. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, and the -M3 suffix confirms JESD 201 Class 2 whisker resistance. These specifications are explicitly stated in the Vishay 3.0C26CA-M3 datasheet section "Mechanical Data".
What is the maximum clamping voltage of the 3.0C26CA-M3 under a 10/1000 μs surge?
The maximum clamping voltage (VC) of the 3.0C26CA-M3 is 42.1 V at 71.3 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured and guaranteed per the electrical characteristics table in Vishay's datasheet 98266. It defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the 3.0C26CA-M3 bidirectional or unidirectional?
The 3.0C26CA-M3 is a bidirectional Transient Voltage Suppressor, as confirmed by its "CA" suffix (denoting bidirectional), absence of polarity marking, and symmetric VBR/VWM specifications. It provides symmetrical clamping for both positive and negative transients, making it suitable for AC lines, differential signals, and floating nodes - a key feature documented in the "Primary Characteristics" section of the Vishay datasheet.
What package type does the 3.0C26CA-M3 use?
The 3.0C26CA-M3 uses the SMC (DO-214AB) surface-mount package, with dimensions 7.11 mm × 6.22 mm × 2.62 mm and a standard mounting pad layout per JEDEC outlines.
