Product details
Overview
3.0C58CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for high-energy surge protection with 3000 W peak pulse power (10/1000 μs), 93.6 V clamping voltage at 32.1 A, and 58 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C58CA-M3/H datasheet, 3.0C58CA-M3/H pinout, 3.0C58CA-M3/H application, or 3.0C58CA-M3/H equivalent, key selection criteria include clamping voltage vs. device operating voltage, bidirectional polarity for AC-coupled lines, SMC package thermal performance (RthJA = 90 °C/W), and IEC 61000-4-2 ESD immunity up to 30 kV.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector triggered by transient overvoltage events. Its bidirectional structure enables symmetrical clamping on both polarities without external polarity management, and its low incremental surge resistance ensures minimal voltage overshoot during fast 8/20 μs surges (121 V @ 248 A).
Designed for robustness in harsh environments, it features a 175 °C maximum junction temperature, meets MSL Level 1 per J-STD-020, and uses halogen-free, RoHS-compliant molding compound with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before conduction begins; must exceed system nominal rail voltage (e.g., 48 V DC bus) with margin. |
| VBR (min/max) | 64.4 V / 71.2 V - Breakdown occurs within this range at 1 mA test current; defines turn-on threshold consistency across production lots. |
| VC @ IPPM | 93.6 V @ 32.1 A (10/1000 μs) - Clamped voltage seen by protected circuit during worst-case surge; determines downstream component voltage stress. |
| PPPM | 3000 W - Peak pulse power handling capability under standardized 10/1000 μs waveform; validates suitability for IEC 61000-4-5 Level 4 surges. |
| IPPM (8/20 μs) | 248 A - Peak surge current survivability under lightning-like 8/20 μs waveform; critical for AC mains and outdoor interface protection. |
| TJ max | 175 °C - Maximum junction temperature rating; supports operation in high-ambient industrial enclosures without derating below full power. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 7.11 mm × 6.22 mm × 2.62 mm (L × W × H); thermal pad layout optimized for FR4 PCB with 2 oz copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (unmarked end) | Surge return path | Internally symmetric - either terminal serves as reference; no functional distinction between pins in bidirectional operation. |
| Anode (unmarked end) | Surge return path | Electrically identical to cathode; device conducts equally in both directions above VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity awareness or external diode pairing. |
| 30 kV ESD immunity (IEC 61000-4-2) | Eliminates need for additional ESD suppression stages on exposed ports such as RS-485 or USB upstream interfaces. |
| Low Rsurge (incremental) | Minimizes voltage overshoot during fast transients, reducing risk of latch-up or gate oxide damage in protected MOSFETs and ICs. |
| MSL Level 1 rating | Permits standard reflow soldering without moisture sensitivity concerns - no baking required prior to assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | Lower PPPM (600 W), same VWM/VC, SMB package (smaller footprint, higher RthJA) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance | Select when space-constrained and surge threat level is limited to IEC 61000-4-5 Level 2. |
| SMCJ58A | Unidirectional, identical VWM/VC/PPPM, same SMC package | Requires external polarity management; not suitable for AC or floating signals | Choose only for DC-rail-only protection where polarity is fixed and known. |
Compared with 3.0C58CA-M3/H, SMBJ58CA offers smaller size but sacrifices >80 % peak power handling, while SMCJ58A matches power and package but lacks bidirectional capability - making 3.0C58CA-M3/H the sole choice for compact, polarity-agnostic, high-energy protection.

FAQ
What is the clamping voltage of the 3.0C58CA-M3/H under a 10/1000 μs surge?
The 3.0C58CA-M3/H has a maximum clamping voltage (VC) of 93.6 V at 32.1 A under the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees predictable overvoltage limiting during common surge events like inductive switching. The 3.0C58CA-M3/H maintains this clamping performance across its specified operating temperature range.
Is the 3.0C58CA-M3/H suitable for protecting 48 V DC systems?
Yes - the 3.0C58CA-M3/H has a 58 V stand-off voltage (VWM) and 64.4–71.2 V breakdown range, providing sufficient margin above 48 V nominal operation while ensuring reliable conduction only during transients. Its 93.6 V clamping voltage remains safely below the 100 V absolute maximum rating of most 48 V system components, making the 3.0C58CA-M3/H a validated choice for such applications.
Does the 3.0C58CA-M3/H require special handling due to moisture sensitivity?
No - the 3.0C58CA-M3/H is rated MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and subjected to standard lead-free reflow profiles (peak 260 °C) without baking or dry-pack requirements. This simplifies manufacturing logistics and eliminates moisture-related yield loss, a key advantage of the 3.0C58CA-M3/H in high-volume SMT lines.
How does the 3.0C58CA-M3/H perform under lightning-surge conditions (8/20 μs)?
The 3.0C58CA-M3/H withstands up to 248 A under the 8/20 μs waveform, with a corresponding clamping voltage of 121 V. This performance aligns with IEC 61000-4-5 Level 4 requirements for medium-risk installations. The 3.0C58CA-M3/H's low incremental surge resistance ensures minimal overshoot, preserving downstream component integrity during fast-rising lightning-induced transients.
What is the thermal resistance of the 3.0C58CA-M3/H when mounted on a standard FR4 PCB?
When mounted on a standard FR4 PCB with 2 oz copper using the recommended footprint, the 3.0C58CA-M3/H exhibits a junction-to-ambient thermal resistance (RthJA) of 90 °C/W. Its junction-to-mount thermal resistance (RthJM) is 4.0 °C/W, enabling effective heat transfer to thermal pads or copper planes - critical for sustained surge duty cycles and high-temperature industrial operation of the 3.0C58CA-M3/H.
