Product details
Overview
3.0SMCJ58A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 58V reverse standoff voltage, 93.6V max clamping voltage at 32.1A peak pulse current, and glass-passivated die construction for robust ESD protection in DC power rails and I/O lines. It delivers IEC-61000-4-2 ±30kV air/contact ESD immunity and operates from –55°C to +150°C.
For engineers reviewing the 3.0SMCJ58A-13 datasheet, 3.0SMCJ58A-13 pinout, 3.0SMCJ58A-13 application, or 3.0SMCJ58A-13 equivalent, this part is selected for high-energy surge suppression in automotive power modules, industrial PLC inputs, telecom DC feeds, and PoE-powered equipment where clamping voltage margin and thermal stability under repetitive transients are critical.
Technical Context
This TVS diode uses a planar junction silicon structure with glass passivation to ensure stable breakdown characteristics and low leakage (<5µA at VRWM). Its unidirectional configuration provides asymmetric clamping-low forward voltage drop during overvoltage events on the cathode-biased side while blocking reverse conduction until breakdown.
The device is rated for 3000W peak pulse power (10/1000µs waveform), supports 300A non-repetitive forward surge current (8.3ms half-sine), and exhibits tight VBR tolerance (64.4–71.2V at 1mA test current), enabling precise coordination with downstream overvoltage protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W (10/1000µs waveform); sustains high-energy lightning-induced surges without thermal runaway |
| Reverse Standoff Voltage (VRWM) | 58V; maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 64.4–71.2V @ 1mA; defines reliable turn-on threshold for transient clamping |
| Max Clamping Voltage (VC) | 93.6V @ 32.1A IPP; limits voltage seen by protected ICs during worst-case surge |
| Peak Pulse Current (IPP) | 32.1A (10/1000µs); quantifies surge-handling capacity under standardized transient stress |
| ESD Rating | ±30kV contact/air per IEC-61000-4-2; protects against human-body and system-level electrostatic discharge |
| Operating Temperature | –55°C to +150°C; validated for under-hood automotive and industrial ambient conditions |
Pinout & Package
Package: SMC (DO-214AB), surface-mount molded plastic body with matte tin-plated leads; UL 94V-0 flammability rating; 0.21g weight; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR |
| Anode | Reference node | Typically tied to system ground or low-impedance return path; completes clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Ensures stable VBR and low leakage across temperature and lifetime; eliminates passivation-related failure modes |
| 3000W peak pulse rating | Supports Level 4 IEC 61000-4-5 surge immunity (4kV line-to-earth) in compact SMC footprint |
| RoHS-compliant & halogen-free | Meets EU RoHS 3 (2015/863/EU) and "Green" definition (<900ppm Br/Cl, <1000ppm Sb) |
| Cathode band marking | Enables unambiguous polarity identification during automated optical inspection and placement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A (Diodes Inc.) | 2000W PPK, same VRWM/VC but lower IPP (22.2A), smaller SMB package | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is ≤Level 3 |
| 1.5SMCJ58A (ON Semiconductor) | 1500W PPK, identical VRWM/VC specs but lower thermal mass and derating above 25°C | Requires larger copper area for equivalent thermal performance; not AEC-Q200 qualified | Choose only for cost-sensitive consumer designs with verified thermal layout |
Compared with SMBJ58A and 1.5SMCJ58A, the 3.0SMCJ58A-13 delivers 50% higher peak power handling and superior thermal stability in SMC package-critical for automotive and industrial applications requiring sustained surge immunity without derating penalties.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ58A-13 under standard test conditions?
The maximum clamping voltage (VC) is 93.6V at 32.1A peak pulse current, measured using the standardized 10/1000µs double-exponential waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range (–55°C to +150°C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 3.0SMCJ58A-13 suitable for bidirectional signal line protection?
No-the 3.0SMCJ58A-13 is a unidirectional TVS diode, identifiable by its cathode band marking. It clamps only when the cathode is positive relative to the anode. For bidirectional AC or differential signal lines, the bi-directional variant 3.0SMCJ58CA-13 must be used, which has symmetric clamping in both polarities and no polarity indicator.
How does the SMC package affect PCB layout and thermal performance?
The SMC (DO-214AB) package requires a minimum 8.00mm² copper pad area per terminal for rated 3000W pulse handling, as specified in the datasheet. Its 6.9mm × 4.4mm footprint supports higher thermal mass than SMB/SMA packages, enabling better heat dissipation during repetitive surges and reducing need for external heatsinking in most industrial applications.
Does the 3.0SMCJ58A-13 meet automotive qualification standards?
The standard 3.0SMCJ58A-13 is not AEC-Q200 qualified; however, Diodes offers automotive-grade variants with Q-suffix (e.g., 3.0SMCJ58AQ-13) that undergo additional stress testing, PPAP documentation, and manufacturing in IATF 16949-certified facilities. These Q-parts are required for under-hood and safety-critical vehicle systems.
