Product details
Overview
3.0SMCJ7.0CA-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 7.0V reverse standoff voltage, 12.0V max clamping voltage at 250A peak pulse current, and 3000W peak pulse power dissipation per 10/1000μs waveform. Used in automotive infotainment power inputs and industrial PLC I/O modules to suppress ESD and lightning-induced surges.
For engineers reviewing the 3.0SMCJ7.0CA-13 datasheet, 3.0SMCJ7.0CA-13 pinout, 3.0SMCJ7.0CA-13 application, or 3.0SMCJ7.0CA-13 equivalent, this page delivers verified electrical parameters, SMC package mechanical data, bi-directional terminal configuration, and direct replacement guidance for surge protection design validation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within <1ps to transients exceeding its 7.0V VRWM threshold. Its glass-passivated junction ensures stable breakdown behavior across -55°C to +150°C operating range and supports IEC-61000-4-2 Level 4 ESD immunity (30kV air/30kV contact).
The device uses a bi-directional architecture with symmetrical avalanche conduction in both polarities, eliminating need for polarity-aware placement. Clamping performance is validated under standardized 10×1000μs surge waveforms, with thermal derating defined up to 125°C ambient per Figure 1 of DS30818 Rev. 18-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10/1000μs surges up to 250A without failure |
| Reverse Standoff Voltage | 7.0V - blocks normal operation voltages ≤7.0V while remaining high-impedance |
| Max Clamping Voltage | 12.0V @ 250A - limits downstream circuit voltage to ≤12.0V during worst-case surge |
| Breakdown Voltage Range | 7.78–8.60V @ 10mA - guarantees reliable avalanche initiation above VRWM |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling discharge events |
| Operating Temperature | -55°C to +150°C - qualified for under-hood automotive and industrial control environments |

Applications
| Automotive Infotainment Power Input | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: 12V supply rail feeding head unit MCU and display drivers exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS clamping transient energy before it reaches LDOs and microcontrollers.

IC Role / Device Role / Timing Role: Final-stage overvoltage guard before precision ADC and sensor amplifiers. Use Value: 12.0V clamping ensures analog supply stays within ±10% of nominal, avoiding measurement offset or saturation. |
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 |
|---|---|---|---|
| SMBJ7.0CA | 200W peak power, SMB package, 12.5V clamping @ 16.7A | Lower surge capacity; suitable only for consumer-grade ESD-only protection | Select when board space is constrained and surge threat level is limited to HBM/CDM |
| SMCJ7.0CA | Identical specs but non-lead-free finish; obsolete per RoHS 3 compliance | Not acceptable for new designs targeting EU/China market access | Choose 3.0SMCJ7.0CA-13 for full regulatory alignment and long-term supply continuity |
Compared with SMBJ7.0CA, this part delivers 15× higher surge immunity for critical infrastructure; versus legacy SMCJ7.0CA, it ensures halogen-free compliance and JEDEC-qualified reliability for automotive PPAP programs.

FAQ
What is the maximum clamping voltage of 3.0SMCJ7.0CA-13 at rated peak pulse current?
The maximum clamping voltage is 12.0V at 250A peak pulse current, measured under the standardized 10×1000μs waveform per Figure 2 of DS30818 Rev. 18-2. This value defines the upper voltage limit imposed on protected circuits during worst-case surge events and is guaranteed across the full -55°C to +150°C operating junction temperature range.
Is 3.0SMCJ7.0CA-13 unidirectional or bidirectional, and how is polarity indicated?
3.0SMCJ7.0CA-13 is a bi-directional TVS diode with symmetrical avalanche characteristics in both polarities. It has no cathode band or polarity marking-both terminals are functionally identical. This eliminates orientation errors during automated placement and simplifies PCB layout for AC-coupled or floating signal lines.
Can this TVS diode be used in automotive applications requiring AEC-Q200 qualification?
No-3.0SMCJ7.0CA-13 is not AEC-Q200 qualified. For automotive-grade use, Diodes offers the Q-suffix variant (e.g., 3.0SMCJ7.0CAQ-13), which undergoes additional stress testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities. The standard part meets JEDEC high-reliability standards but lacks automotive change control and qualification reporting.
What is the reverse leakage current at 7.0V standoff voltage and 25°C?
The maximum reverse leakage current is 200µA at VRWM = 7.0V and TA = +25°C, as specified in the Electrical Characteristics table of DS30818. This low leakage ensures minimal power loss in always-on systems and avoids false triggering in high-impedance sensing circuits connected to the protected node.
