Product details
Overview
3.0SMCJ58CA-13 from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It delivers 3000W peak pulse power dissipation, clamps transients up to 93.6V at 32.1A (10/1000μs waveform), and features a 58V reverse standoff voltage with ±5% tolerance. Used in industrial power supplies, automotive body control modules, and PoE-powered equipment to meet IEC-61000-4-2 ESD immunity requirements.
For engineers reviewing the 3.0SMCJ58CA-13 datasheet, 3.0SMCJ58CA-13 pinout, 3.0SMCJ58CA-13 application, or 3.0SMCJ58CA-13 equivalent, this device is selected for robust overvoltage protection where fast response (<1ns), low clamping ratio (VC/VRWM = 1.61), and AEC-Q200-compatible reliability are required - especially in 48V battery systems, CAN bus interfaces, and DC-DC converter input stages.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior under repetitive surge stress and supports operation from –55°C to +150°C junction temperature.
The device uses a planar silicon avalanche structure optimized for low dynamic impedance (ZPP ≈ 2.92Ω calculated from VC/IPP), delivering consistent clamping performance across its 3000W rating. It complies with IEC-61000-4-2 (30kV air/30kV contact), HBM (8kV), CDM (1kV), and MM (800V) ESD standards - verified per JEDEC JESD22-A114 and JESD22-C101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs surges up to 32.1A without failure |
| Reverse Standoff Voltage (VRWM) | 58.0V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage (VBR) | 64.4–71.2V @ 1.0mA - guaranteed avalanche initiation range for predictable triggering |
| Clamping Voltage (VC) | 93.6V @ 32.1A - limits downstream circuit voltage during worst-case surge |
| Leakage Current (IR) | ≤5.0μA @ 58V - negligible standby power loss in always-on systems |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling events |
| Operating Temperature | –55°C to +150°C - qualified for under-hood automotive and industrial environments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating. Dimensions: 7.11mm × 6.22mm × 2.75mm (L × W × H). Matte tin-plated leads, solderable per MIL-STD-202 Method 208. Bi-directional configuration - no cathode band or polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Terminal 1) | Surge current entry (positive polarity) | Connects to protected line; forms one side of symmetrical avalanche path |
| Cathode (Terminal 2) | Surge current entry (negative polarity) | Connects to protected line; identical electrical role as Terminal 1 in bi-directional mode |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC signals or floating buses without polarity concerns |
| Glass-passivated die | Ensures long-term parameter stability and resistance to humidity-induced degradation |

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-13 (Diodes Inc.) | Same VRWM and VC, but 600W rating (vs. 3000W); SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy surges (e.g., board-level ESD only); unsuitable for load dump or ISO 7637-2 compliance | Select when space-constrained and surge energy ≤600W; verify thermal derating in high-ambient designs |
| 1.5SMCJ58CA (ON Semiconductor) | Identical 3000W rating, 58V VRWM, and SMC package; minor VBR tolerance difference (±5% vs. ±6.5%) | Drop-in compatible in layout and function; same IEC-61000-4-2 and AEC-Q200 qualification level | Preferred for dual-sourcing; verify date-code traceability and lot-specific leakage testing if used in safety-critical BOMs |
Compared with SMBJ58CA-13, the 3.0SMCJ58CA-13 provides five times higher surge capacity for system-level immunity; versus 1.5SMCJ58CA, it offers tighter VBR tolerance and updated RoHS 3/halogen-free compliance - critical for new automotive program launches.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ58CA-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 93.6V at 32.1A peak pulse current, measured using the standardized 10×1000μs 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 circuits during surge events.
Is the 3.0SMCJ58CA-13 suitable for automotive applications requiring AEC-Q200 qualification?
Yes - the 3.0SMCJ58CA-13 is manufactured in IATF 16949-certified facilities and qualified to AEC-Q200 stress test conditions. It meets the environmental and reliability requirements for automotive body electronics, including thermal cycling, humidity bias, and mechanical shock testing, and is listed in Diodes' automotive-grade product catalog.
How does the bi-directional configuration affect PCB layout compared to uni-directional TVS diodes?
Bi-directional operation eliminates the need for polarity-aware placement: terminals are electrically interchangeable, allowing direct connection across any two nodes without cathode-band orientation checks. This simplifies layout, reduces assembly errors, and enables symmetric protection of differential pairs or AC-coupled lines without additional routing constraints.
What is the moisture sensitivity level (MSL) and reflow profile compatibility for the SMC package?
The SMC package carries MSL Level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without baking. It supports standard lead-free reflow profiles with peak temperatures up to 260°C, and its matte tin finish ensures reliable solder wetting per MIL-STD-202 Method 208.
