Product details
Overview
3.0SMCJ11CA-13 from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 11.0 V reverse standoff voltage (VRWM), 18.2 V maximum clamping voltage (VC) at 164.8 A peak pulse current (IPP), and 3000 W peak pulse power dissipation per 10×1000 µs waveform - enabling reliable surge suppression in industrial power supplies and automotive ECUs.
For engineers reviewing the 3.0SMCJ11CA-13 datasheet, 3.0SMCJ11CA-13 pinout, 3.0SMCJ11CA-13 application, or 3.0SMCJ11CA-13 equivalent, key selection criteria include clamping performance under IEC 61000-4-2 ESD (30 kV air/30 kV contact), bi-directional symmetry for AC-coupled or floating interfaces, and SMC package thermal derating above +25°C ambient.
Technical Context
This TVS operates as a voltage-clamped shunt protector: during transients exceeding VRWM = 11.0 V, it avalanches to limit voltage across protected circuitry to ≤18.2 V. Its glass-passivated junction ensures stable breakdown and low leakage (≤5.0 µA at VRWM), while bi-directional symmetry eliminates polarity concerns in differential or AC signal paths.
The device meets IEC 61000-4-2 Level 4 ESD immunity (30 kV air, 30 kV contact) and supports high-reliability applications with operating junction temperature range of –55°C to +150°C, JEDEC-qualified reliability, and RoHS-compliant, halogen-free "Green" construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000 W - sustains 10×1000 µs surges without failure, suitable for lightning-induced transients per IEC 61000-4-5. |
| Reverse Standoff Voltage | 11.0 V - maximum continuous DC or RMS voltage before clamping initiates; sets minimum operating margin for 12 V systems. |
| Clamping Voltage | 18.2 V @ 164.8 A - limits transient voltage seen by downstream ICs; enables safe operation of 16 V-rated components. |
| ESD Rating | 30 kV (air) / 30 kV (contact) per IEC 61000-4-2 - protects against human-handling ESD events without external shielding. |
| Package | SMC (DO-214AB) - surface-mount outline with 7.75–8.13 mm body length, optimized for 8 mm² copper land area per terminal. |
| Operating Temperature | –55°C to +150°C - supports under-hood automotive, industrial motor drives, and outdoor power equipment. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic, UL 94V-0 rated, matte tin-plated leads, 0.21 g typical weight. Bi-directional configuration - no cathode band; terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient shunt path | Either terminal serves as input/output; bidirectional conduction allows placement on AC lines or floating buses without orientation check. |
| Cathode Band (N/A) | Polarity indicator | Not present - confirms bi-directional functionality; eliminates risk of reverse installation in differential or isolated circuits. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Enables single-device protection against severe surges (e.g., ISO 7637-2 Pulse 1/2/5a in 12 V automotive systems). |
| Glass-passivated die | Ensures stable breakdown voltage over lifetime and improved humidity resistance vs. epoxy-passivated alternatives. |
| Bi-directional architecture | Supports protection of AC-coupled interfaces (e.g., RS-485, CAN FD, Ethernet PHYs) without polarity-sensitive layout constraints. |
| JEDEC-qualified reliability | Validated for high-reliability use per AEC-Q standards; suitable for PPAP-capable automotive programs when paired with Q-suffix variants. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

Use Scenario: Protecting 12 V DC input rails in programmable logic controllers (PLCs) exposed to load dump and inductive switching transients. IC Role / Device Role: Shunt-type transient suppressor placed at board-level input connector to clamp surges before they reach DC-DC converters and microcontrollers. Use Value: Clamps 164.8 A transients to ≤18.2 V, preventing latch-up or permanent damage to 24 V-tolerant interface ICs and maintaining system uptime. |
Use Scenario: Safeguarding LIN bus and sensor supply lines in BCMs subjected to battery reversal, jump-start spikes, and ESD during assembly. IC Role / Device Role: Bi-directional TVS on 12 V sensor rail and LIN transceiver VCC line to absorb both positive and negative polarity transients. Use Value: Eliminates need for dual unidirectional devices; maintains signal integrity during 30 kV ESD events without disrupting LIN communication timing. |
| RS-485 Communication Interface | Smart Energy Meter Input Stage |
|
Use Scenario: Protecting differential RS-485 transceivers (e.g., MAX1487) in utility substation telemetry links exposed to induced lightning surges. IC Role / Device Role: Common-mode TVS across A/B lines and to ground, leveraging bi-directional symmetry to suppress both polarities of common-mode transients. Use Value: Limits common-mode voltage excursion to <18.2 V, preserving transceiver common-mode range and preventing false data corruption or receiver saturation. |
Use Scenario: Securing AC/DC auxiliary power input (rectified 24 V) in DIN-rail energy meters deployed in electric utility substations. IC Role / Device Role: Primary surge clamp on rectified DC bus, coordinated with MOVs and fuses to meet IEC 61000-4-5 Level 3 (2 kV line-earth). Use Value: Absorbs 3000 W surge energy without degradation, extending meter service life in high-lightning-risk regions and reducing field return rates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA-13 (Diodes Inc.) | Same VRWM (11 V) and VC (18.2 V), but lower PPK = 600 W and IPP = 33 A - uses SMB package (smaller footprint, lower thermal mass). | Limited to lower-energy transients (e.g., HBM ESD only); unsuitable for ISO 7637-2 or IEC 61000-4-5 surges. | Select when space-constrained PCBs require smaller footprint and surge threat level is limited to board-level ESD. |
| 1.5SMC11CA (ON Semiconductor) | Identical VRWM (11 V), VC (18.2 V), and PPK (3000 W), but rated for 1500 W average power handling and slightly higher IR (10 µA max). | Same surge capability but tighter thermal design margin due to older SMC package variant; not qualified to latest JEDEC reliability standards. | Acceptable for legacy designs where second-source qualification is required, but prefer 3.0SMCJ11CA-13 for new automotive or industrial programs. |
Compared with SMBJ11CA-13, the 3.0SMCJ11CA-13 delivers five times higher surge energy handling; versus 1.5SMC11CA, it offers enhanced process control, JEDEC reliability validation, and tighter leakage specification - critical for long-life industrial deployments.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ11CA-13 under standard test conditions?
The maximum clamping voltage (VC) is 18.2 V when subjected to a 10×1000 µs transient waveform at a peak pulse current (IPP) of 164.8 A. This value is measured per IEC 61000-4-5 test methodology and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is the 3.0SMCJ11CA-13 suitable for automotive applications?
Yes - it meets JEDEC reliability standards and is part of Diodes' AEC-Q qualified product family. While the -13 suffix denotes commercial-grade packaging, the underlying die and process are used in automotive-qualified variants (e.g., 3.0SMCJ11CAQ-13), making it appropriate for non-safety-critical automotive subsystems like infotainment power rails and sensor interfaces.
How does the bi-directional configuration affect PCB layout?
The absence of a cathode band means both terminals are functionally identical; no orientation check is needed during placement. This simplifies automated assembly, eliminates polarity-related rework, and enables symmetric routing on differential lines such as RS-485 or CAN, where consistent impedance and layout balance are critical.
What thermal derating applies above +25°C ambient temperature?
Per Figure 1 in DS30818 Rev. 18, peak pulse power must be linearly derated from 100% at +25°C to ~50% at +125°C ambient. For example, at +85°C, maximum usable PPK is ~75% of 3000 W (i.e., 2250 W), requiring system-level thermal analysis to ensure adequate copper land area and airflow for sustained surge duty cycles.
