Product details
Overview
3.0SMCJ11A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 11V reverse standoff voltage, 12.2–13.5V breakdown range at 1mA, and 18.2V max clamping voltage at 164.8A peak pulse current. It features glass-passivated die construction, IEC-61000-4-2 ESD immunity (30kV air/contact), and is rated for automotive-grade reliability per AEC-Q standards when qualified with Q-suffix variants.
For engineers reviewing the 3.0SMCJ11A-13 datasheet, 3.0SMCJ11A-13 pinout, 3.0SMCJ11A-13 application, or 3.0SMCJ11A-13 equivalent, key selection criteria include clamping voltage margin versus system rail, 8.3ms surge current handling (300A IFSM), JEDEC-compliant thermal performance (−55°C to +150°C), and SMC package compatibility with high-power PCB layouts requiring UL 94V-0 molded plastic housing.
Technical Context
This TVS diode operates as a unidirectional clamping device in DC power rails and signal lines, triggering conduction above its 12.2V minimum breakdown threshold to divert transient energy away from downstream ICs. Its 18.2V clamping voltage at 164.8A ensures robust protection for 12V systems under IEC 61000-4-5 10/1000μs surge events.
The SMC package enables high thermal dissipation with 0.21g mass and 8.00mm² copper land requirement, while glass passivation delivers stable leakage (<5μA at 11V) and long-term reliability across −55°C to +150°C junction temperature range. It supports both industrial and automotive applications where AEC-Q200-compliant variants are available.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs transients without failure |
| Reverse Standoff Voltage (VRWM) | 11.0V - maximum continuous DC voltage before leakage exceeds 5μA |
| Breakdown Voltage (VBR) | 12.2–13.5V @ 1mA - precise conduction onset for predictable clamping |
| Clamping Voltage (VC) | 18.2V @ 164.8A - limits voltage seen by protected circuit during surge |
| Peak Surge Current (IPP) | 164.8A - handles IEC 61000-4-5 Level 4 surges on 12V lines |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human handling events |
| Operating Temperature | −55°C to +150°C - suitable for under-hood automotive and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A (Diodes Inc.) | Lower 600W peak power, same 11V VRWM and 18.2V VC, SMB package (smaller footprint, lower thermal mass) | Best suited for space-constrained consumer electronics with lower surge exposure (IEC 61000-4-2 only) | Select when board area is critical and surge threat level is limited to ESD and minor inductive spikes |
| 1.5SMC11A (ON Semiconductor) | Same 11V VRWM and 18.2V VC, but 1500W peak power and slightly higher IR (10μA vs. 5μA at VRWM) | Valid for industrial control where full 3000W capability is not required and cost optimization is prioritized | Choose when legacy design reuse or dual-sourcing mandates ON Semi footprint compatibility (SMC package identical) |
Compared with SMBJ11A and 1.5SMC11A, the 3.0SMCJ11A-13 delivers double the surge energy handling of the SMBJ and twice the peak power of the 1.5SMC series-making it the only option among the three qualified for sustained 3000W transients in automotive and heavy industrial settings.

FAQ
What is the difference between 3.0SMCJ11A-13 and 3.0SMCJ11CA-13?
The "A" suffix denotes unidirectional operation with cathode band marking, while "CA" indicates bidirectional configuration with no polarity indicator. Both share identical VRWM (11V), VBR (12.2–13.5V), and VC (18.2V), but the unidirectional version offers lower leakage (<5μA vs. 10μA for bi-directional at VRWM) and is preferred for DC rail protection where polarity is fixed.
Can 3.0SMCJ11A-13 be used in place of a 12V Zener diode for overvoltage protection?
No-it is not a regulating device. Unlike Zener diodes, this TVS operates only during transient overvoltage events and does not regulate steady-state voltage. Its role is clamping, not regulation; using it as a Zener replacement would result in uncontrolled conduction and potential failure under continuous overvoltage conditions.
What PCB layout practices maximize thermal performance for this SMC package?
Mount the device on ≥8.00mm² copper land areas per pad (as specified in datasheet note 6), use thermal vias under pads connected to internal ground planes, and avoid placing heat-sensitive components within 2mm. The SMC's 0.21g mass and UL 94V-0 molding require adequate copper area to sustain 3000W pulses without solder joint fatigue.
Is 3.0SMCJ11A-13 qualified for automotive applications per AEC-Q200?
The base part is not AEC-Q200 qualified; however, Diodes offers automotive-grade equivalents with "Q" suffix (e.g., 3.0SMCJ11AQ-13) that meet AEC-Q200 stress testing, PPAP documentation, and IATF 16949 manufacturing requirements. These variants share identical electrical specs but include extended reliability validation for under-hood deployment.
