Product details
Overview
3.0SMCJ10CA-13 from Diodes Incorporated is a bi-directional 3000W surface-mount transient voltage suppressor (TVS) with 10V reverse standoff voltage, 17.0V max clamping voltage at 176.5A peak pulse current, and IEC-61000-4-2 ESD rating of 30kV (air/contact). It protects DC power rails and signal lines in industrial motor drives, telecom power supplies, and automotive body control modules against lightning-induced surges and ESD events.
For engineers reviewing the 3.0SMCJ10CA-13 datasheet, 3.0SMCJ10CA-13 pinout, 3.0SMCJ10CA-13 application, or 3.0SMCJ10CA-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, peak pulse current handling under 10/1000μs waveform, thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust protection of AC-coupled interfaces and floating bus lines without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5.0μA at 10V VRWM) over temperature.
The device sustains 3000W peak pulse power per 10×1000μs waveform and supports 300A non-repetitive forward surge current (8.3ms half-sine), making it suitable for high-energy transients in 48V industrial systems and 12V/24V automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - Handles high-energy lightning surges per IEC 61000-4-5 Level 4 (4kV line-to-line). |
| Reverse Standoff Voltage | 10.0V - Maximum continuous DC or RMS voltage before significant leakage; sets minimum operating rail margin. |
| Max Clamping Voltage | 17.0V @ 176.5A - Limits transient voltage seen by downstream ICs; critical for protecting 12V-rated components. |
| Breakdown Voltage | 11.10–12.27V @ 1.0mA - Tight VBR tolerance ensures predictable turn-on during fast-rising transients. |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - Protects human-accessible ports without external ESD diodes. |
| Operating Temp Range | −55°C to +150°C - Qualified for under-hood automotive and industrial environments with wide thermal cycling. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic, UL 94V-0 rated, 0.21g weight. Matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Bi-directional terminal pair | No polarity marking; symmetrical terminals enable AC line protection without orientation dependency. |
| Anode (Cathode) | Bi-directional terminal pair | Identical electrical behavior in reverse bias; both pins conduct equally during positive/negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Ensures stable VBR and low leakage drift over 1000+ thermal cycles in harsh environments. |
| 3000W peak pulse power | Supports single-event surge immunity up to 4kV (line-earth) in 2Ω source impedance per IEC 61000-4-5. |
| IEC-61000-4-2 ESD 30kV (air/contact) | Eliminates need for secondary ESD protection on exposed connectors in industrial HMI and sensor nodes. |
| RoHS-compliant, halogen-free "Green" | Meets automotive PPAP requirements for Br <900ppm, Cl <900ppm, Sb <1000ppm; supports IATF 16949 manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-13 (Diodes Inc.) | Same VRWM and VC, but 600W PPK; SMC package replaced by smaller SMB (DO-214AA). | Lower energy handling limits use to low-risk consumer or office equipment; unsuitable for industrial surge testing. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 only. |
| 1.5SMC10CA (ON Semiconductor) | Same 10V VRWM, 17V VC, but 1500W PPK; identical SMC package and pinout. | Half the peak power rating reduces margin for multi-pulse or long-duration transients in heavy industrial settings. | Acceptable for cost-sensitive designs where full 3000W capability is not required by end-equipment standards. |
Compared with SMBJ10CA-13 and 1.5SMC10CA, the 3.0SMCJ10CA-13 delivers double the pulse power of the latter and five times that of the former-enabling compliance with IEC 61000-4-5 Level 4 while retaining SMC footprint compatibility for drop-in upgrades.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ10CA-13 under standard test conditions?
The maximum clamping voltage is 17.0V when subjected to a 10×1000μs waveform at 176.5A peak pulse current, measured per JEDEC-standard test method. This value is guaranteed across the full −55°C to +150°C operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 3.0SMCJ10CA-13 suitable for automotive applications?
Yes-the device meets AEC-Q101 stress test requirements and is manufactured in IATF 16949-certified facilities. While the standard part lacks PPAP documentation, its electrical and thermal specifications align with automotive body electronics needs, including LIN bus and 12V power rail protection in door modules and lighting ECUs.
How does the bi-directional configuration affect PCB layout compared to uni-directional TVS diodes?
The bi-directional 3.0SMCJ10CA-13 has no cathode band and identical terminals, eliminating polarity-aware placement errors. This simplifies layout for AC-coupled interfaces like RS-485 or CAN bus, reduces assembly defects, and allows direct replacement of uni-directional parts in differential signal paths without redesigning trace routing.
What is the thermal derating behavior above +25°C ambient temperature?
Per Figure 1 in DS30818 Rev. 18, peak pulse power derates linearly from 100% at +25°C to ~50% at +125°C ambient. At +150°C, it retains ~35% of rated 3000W capability. This must be factored into worst-case surge margin calculations for enclosed enclosures or high-temperature engine bay locations.
