Product details
Overview
3.0SMCJ17CA-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 275V at 10.9A (10×1000μs waveform), and features a 17V reverse standoff voltage with 20.9V minimum breakdown voltage. It is used in industrial power supplies, automotive body electronics, and PoE-powered equipment to protect downstream ICs from ESD and lightning-induced surges.
For engineers reviewing the 3.0SMCJ17CA-13 datasheet, 3.0SMCJ17CA-13 pinout, 3.0SMCJ17CA-13 application, or 3.0SMCJ17CA-13 equivalent, key selection criteria include clamping voltage margin relative to protected circuit VMAX, IPP capability under system-level surge profiles (IEC 61000-4-5), thermal derating above +25°C ambient, and compatibility with SMC footprint layout constraints.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust protection of AC-coupled interfaces or ungrounded differential buses without polarity concerns. Its glass-passivated junction ensures stable leakage (<5µA @ 17V) and repeatable breakdown behavior over temperature (-55°C to +150°C).
The device complies with IEC 61000-4-2 ESD immunity (30kV air/30kV contact) and meets JEDEC high-reliability standards. Clamping performance is specified per 10×1000μs waveform, with peak current limited by thermal mass and package thermal resistance-derating begins above +25°C per Fig. 1 in DS30818 Rev. 18-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs surges up to 10.9A without failure |
| Reverse Standoff Voltage (VRWM) | 17V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage (VBR) | 18.9–20.9V @ 1mA - defines onset of avalanche conduction during overvoltage events |
| Clamping Voltage (VC) | 27.6V @ 10.9A - maximum voltage seen by protected circuit during rated surge |
| ESD Rating | 30kV air / 30kV contact per IEC 61000-4-2 - qualifies for front-panel and connector-level ESD hardening |
| Operating Temperature | -55°C to +150°C - supports under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - surface-mount footprint compatible with IPC-7351B standard land patterns |
Pinout & Package
3.0SMCJ17CA-13 uses the SMC (DO-214AB) plastic package: molded epoxy body, matte tin-plated leads, UL 94V-0 flammability rating, and 0.21g typical weight. Terminals are non-polarized due to bi-directional construction-no cathode band or polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically; bidirectional clamping occurs regardless of voltage polarity |
| Case / Body | Thermal mass & mechanical anchor | Plastic body provides primary heat sinking; requires ≥8mm² copper pad per terminal for full 3000W rating |
Key Features
| Feature | Design Value |
|---|---|
| 3000W peak pulse rating | Enables protection against severe IEC 61000-4-5 Level 4 surges (4kV line-earth) on 24V/48V systems |
| Glass-passivated die | Ensures low leakage (<5µA @ VRWM) and stable VBR over 1000+ surge cycles |
| Bi-directional symmetry | Eliminates orientation errors during placement and protects AC signals or floating buses without external polarity logic |
| RoHS 3 & Halogen-free | Meets EU Directive 2015/863/EU with <900ppm Br, <900ppm Cl, <1000ppm Sb - compliant for green manufacturing |
| JEDEC-qualified reliability | Validated per AEC-Q stress test conditions - suitable for automotive ECUs requiring PPAP documentation |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: 24V DC input rail of programmable logic controller (PLC) exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converter input stage. Use Value: Limits transient voltage to ≤27.6V, preventing damage to 36V-rated input MOSFETs and maintaining system uptime during factory floor surges. |
Use Scenario: LIN bus transceiver power supply in door module subjected to battery disconnect transients. IC Role / Device Role / Timing Role: Standoff protector on VCC line, activated within nanoseconds of overvoltage onset. Use Value: Clamps 100V/10ms load dump spikes to safe levels before LIN PHY ICs experience latch-up or gate oxide stress. |
| POE-Powered Surveillance Camera | RS-485 Communication Interface |
|
Use Scenario: 48V power input of IP camera connected via IEEE 802.3af/at PoE switch in outdoor mounting. IC Role / Device Role / Timing Role: First-line defense against Ethernet cable-induced surges entering via PSE interface. Use Value: Absorbs >2000W common-mode surges while maintaining <5µA leakage to avoid degrading PoE classification accuracy. |
Use Scenario: Termination point of long-haul RS-485 trunk line in building automation system vulnerable to induced lightning currents. IC Role / Device Role / Timing Role: Bi-directional clamp across differential pair (A/B) and ground reference. Use Value: Symmetric clamping prevents data corruption during ±15kV ESD events and holds bus voltage within ±12V common-mode range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17CA-13 | Lower 600W peak power rating; same 17V VRWM, but 27.6V VC at only 21.8A | Suitable for lower-energy threats (IEC 61000-4-2 only); insufficient for IEC 61000-4-5 Level 3+ | Select when board space is constrained (SMB vs SMC) and surge energy is limited to <100mJ |
| 1.5SMCJ17CA-13 | 1500W peak power; identical VRWM/VBR/VC specs but half the IPP (5.45A) | Matches cost-sensitive consumer electronics where full 3000W is not required | Choose for BOM cost reduction where system-level testing confirms 1500W suffices |
Compared with SMBJ17CA-13 and 1.5SMCJ17CA-13, the 3.0SMCJ17CA-13 provides double the surge energy handling of the latter and five times that of the former-critical for industrial and automotive applications where sustained high-current transients must be absorbed without degradation.

FAQ
Is 3.0SMCJ17CA-13 unidirectional or bidirectional?
It is a bi-directional TVS diode, confirmed by the "CA" suffix in the part number and absence of cathode band marking. Electrical characteristics table shows identical parameters for both polarities, and its use in AC-coupled or floating differential interfaces is explicitly supported in the datasheet's application guidance.
What is the maximum clamping voltage at rated peak current?
The maximum clamping voltage is 27.6V at 10.9A peak pulse current, measured using the standardized 10×1000μs waveform per Note 11 in DS30818 Rev. 18-2. This value is guaranteed across -55°C to +150°C operating temperature range and defines the upper voltage limit imposed on protected circuits during surge events.
Can this TVS replace older SMCJ series parts in existing designs?
Yes-3.0SMCJ17CA-13 maintains identical SMC (DO-214AB) package dimensions, solder pad layout, and electrical specifications as legacy SMCJ17CA variants. The "3.0" prefix denotes updated process and qualification (JEDEC high-reliability, RoHS 3), with no changes to pinout, thermal profile, or surge performance.
Does it meet automotive qualification requirements?
While 3.0SMCJ17CA-13 itself is not AEC-Q200 qualified, Diodes offers automotive-grade equivalents (e.g., 3.0SMCJ17CAQ-13) with full PPAP documentation, AEC-Q200 stress testing, and IATF 16949 manufacturing. The standard part shares the same die and construction but lacks formal automotive change control and lot traceability.
