Product details
Overview
3.0SMCJ5.0CA-13 from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It delivers 3000W peak pulse power dissipation at 10×1000μs waveform, clamps transients to ≤9.2V at 326.1A peak current, and maintains ≤1000μA reverse leakage at 5.0V standoff voltage. It is used in automotive infotainment power inputs and industrial PLC I/O modules.
For engineers reviewing the 3.0SMCJ5.0CA-13 datasheet, 3.0SMCJ5.0CA-13 pinout, 3.0SMCJ5.0CA-13 application, or 3.0SMCJ5.0CA-13 equivalent, key selection criteria include clamping voltage vs. protected IC VDD, peak pulse current capability under IEC 61000-4-5 surge, standoff voltage margin relative to operating rail, and SMC package thermal performance on 8mm² copper land.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with breakdown voltage specified at 6.40–7.07V (min/max) under 10mA test current. Its glass-passivated junction ensures stable avalanche characteristics and low capacitance (<100pF typical), enabling effective suppression of fast-rising ESD (±30kV air/contact per IEC 61000-4-2) and lightning-induced surges without signal distortion.
Thermal derating follows a defined curve: peak pulse power drops linearly to 50% at +125°C ambient and fully de-rates above +150°C junction temperature. The device sustains 300A non-repetitive forward surge (8.3ms half-sine) when mounted on 8.00mm² copper land, confirming suitability for high-energy industrial transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - Sustains 10×1000μs surge events without failure in telecom/industrial power rails. |
| Reverse Standoff Voltage | 5.0V - Maximum continuous DC voltage before significant leakage; sets minimum operating margin above 3.3V/5V rails. |
| Clamping Voltage @ IPP | 9.2V @ 326.1A - Limits transient voltage seen by downstream ICs during 10×1000μs surge, protecting 12V-tolerant interfaces. |
| Breakdown Voltage Range | 6.40–7.07V @ 10mA - Ensures reliable avalanche initiation within tight tolerance, critical for consistent protection timing. |
| ESD Rating | ±30kV air / ±30kV contact (IEC 61000-4-2) - Meets Level 4 immunity for exposed connectors in medical and automotive applications. |
| Junction Temperature Range | −55°C to +150°C - Supports operation in engine bay, outdoor enclosures, and industrial control cabinets without derating. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA | 200W peak power, same 5.0V VRWM and bi-directional configuration but lower clamping (9.2V) and smaller SMC footprint. | Limited to low-energy surges (e.g., USB ports); insufficient for IEC 61000-4-5 Level 3+ or automotive load dump. | Select only for space-constrained consumer electronics where 3000W rating is unnecessary. |
| 1.5SMCJ5.0CA | 1500W peak power, identical SMC package and electrical specs except halved PPK; same thermal derating and JEDEC qualification. | Suitable for cost-sensitive industrial controls with moderate surge exposure (e.g., indoor factory automation). | Choose when full 3000W headroom is not required and BOM cost reduction is prioritized without sacrificing footprint or reliability. |
Compared with SMBJ5.0CA and 1.5SMCJ5.0CA, the 3.0SMCJ5.0CA-13 provides double the surge energy handling of the latter and 15× more peak power than the former-enabling single-device protection in high-risk environments like automotive power domains and outdoor telecom infrastructure.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ5.0CA-13 under standard test conditions?
The maximum clamping voltage is 9.2V, measured at 326.1A peak pulse current using the standardized 10×1000μs waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range (−55°C to +150°C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 3.0SMCJ5.0CA-13 suitable for automotive applications?
Yes-the device is JEDEC-qualified for high reliability and manufactured in IATF 16949-certified facilities. While the standard part lacks AEC-Q200 certification, Diodes offers automotive-grade Q-suffix variants (e.g., 3.0SMCJ5.0CAQ-13) with full PPAP documentation, making it suitable for non-safety-critical automotive subsystems like infotainment and body electronics.
How does the bi-directional configuration affect PCB layout compared to uni-directional TVS diodes?
Bi-directional operation eliminates polarity marking requirements: no cathode band is present, and either terminal may connect to the protected line or ground. This simplifies layout in AC-coupled or floating interfaces (e.g., RS-485, CAN bus stubs) and avoids orientation errors during automated assembly-reducing rework and field failure risk.
What thermal derating applies to the 3.0SMCJ5.0CA-13 at elevated ambient temperatures?
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, power handling drops to zero. Derating assumes mounting on 8.00mm² copper land; reduced copper area requires additional derating per thermal simulation or empirical testing.
