Product details
Overview
3.0SMCJ5.0A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection on DC power rails and signal lines. It features a 5.0V reverse standoff voltage, 9.2V max clamping voltage at 326.1A peak pulse current, and IEC-61000-4-2 ESD immunity up to 30kV (air/contact), making it suitable for industrial power supply input protection.
For engineers reviewing the 3.0SMCJ5.0A-13 datasheet, 3.0SMCJ5.0A-13 pinout, 3.0SMCJ5.0A-13 application, or 3.0SMCJ5.0A-13 equivalent, this TVS diode delivers verified clamping performance under 10/1000μs surge waveforms, supports JEDEC-compliant high-reliability deployment, and requires attention to SMC package thermal land design per J-STD-020 Level 1 moisture sensitivity handling.
Technical Context
This unidirectional TVS operates as a voltage-clamped crowbar device triggered by transient overvoltage events exceeding its 5.0V VRWM. Its glass-passivated silicon junction ensures stable breakdown at 6.40–7.07V (tested at 10mA), with sub-100ns response time to suppress fast-rising ESD and lightning-induced surges.
The device sustains 3000W peak pulse power per 10×1000μs waveform and handles up to 300A non-repetitive forward surge current (8.3ms half-sine). Thermal derating begins above +25°C ambient, with full power rated only at TA ≤ +25°C and linear reduction per Figure 1 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - Sustains single 10×1000μs transients without failure; defines maximum energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 5.0V - Maximum continuous DC or RMS voltage before significant leakage; sets operating rail compatibility |
| Breakdown Voltage (VBR) | 6.40–7.07V @ 10mA - Confirmed avalanche initiation range; ensures reliable triggering above normal operating voltage |
| Max Clamping Voltage (VC) | 9.2V @ 326.1A - Upper voltage limit seen by protected circuit during worst-case 3000W surge; determines downstream IC survivability |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - Validated immunity level for system-level ESD testing compliance |
| Operating Temperature | −55°C to +150°C - Enables use in automotive engine compartments and industrial outdoor enclosures |
Pinout & Package
Package: SMC (DO-214AB), surface-mount molded plastic body with matte tin-plated leads; UL 94V-0 flammability rating; 0.21g weight; cathode band indicates polarity for unidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection to protected line | Connected to ground or low-impedance return path; completes clamping loop during overvoltage event |
| Cathode | High-side connection to protected line | Marked by visible band; ties to power rail or signal line requiring protection; conducts surge current to ground |
Key Features
| Feature | Design Value |
|---|---|

| Glass Passivated Die | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure |
| IEC-61000-4-2 ESD Rating | Eliminates need for additional ESD stages in front-end interfaces like USB, RS-485, or sensor inputs |
| RoHS & Halogen-Free Compliance | Meets EU Directive 2015/863/EU and automotive "Green" requirements (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 12V DC input stage of programmable logic controllers (PLCs) exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converters and microcontrollers. Use Value: Limits transient voltage to ≤9.2V during 3000W surges, preventing latch-up or gate oxide damage in downstream 5V/3.3V logic. |
Use Scenario: CAN bus power rail protection in BCM units subject to battery reversal and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS tied between VBAT and chassis ground to absorb negative-going spikes. Use Value: Withstands −300A reverse surge (per IEC 61000-4-5) while maintaining <10µA leakage at 5V, preserving sleep-mode current budget. |
| RS-485 Transceiver Interface | Smart Meter AC/DC Power Supply |
Use Scenario: Differential data line protection in utility-grade RS-485 nodes deployed in substations. IC Role / Device Role / Timing Role: Paired back-to-back devices (or bi-directional variant) across A/B lines to clamp common-mode surges. Use Value: Sub-100ns response ensures clamping occurs before transceiver input structures experience destructive voltage stress. |
Use Scenario: Secondary-side 5V output rail protection in DIN-rail mounted smart meters with auxiliary power supplies. IC Role / Device Role / Timing Role: Final-stage TVS after isolation barrier, guarding metering SoC and RTC backup circuits. Use Value: 9.2V clamping guarantees safe operation of 5V LDOs and flash memory even during sustained 100ms overvoltage events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A | 600W peak power, same VRWM and VC; smaller SMB package (lower thermal mass) | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable for load dump | Select when board space is constrained and surge threat level is limited to ESD and minor coupling events. |
| 1.5SMCJ5.0A | 1500W peak power, identical SMC package footprint and pinout | Half the energy handling; requires parallel placement for 3000W equivalence | Choose for cost-sensitive designs where dual-device layout and routing overhead are acceptable trade-offs. |
Compared with SMBJ5.0A and 1.5SMCJ5.0A, the 3.0SMCJ5.0A-13 provides double the surge energy margin of the latter and five times the peak power of the former-critical for automotive and industrial applications where single-point protection must survive worst-case ISO 7637-2 and IEC 61000-4-5 transients without redundancy.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ5.0A-13 under a 3000W surge?
The maximum clamping voltage is 9.2V when subjected to a 326.1A peak pulse current defined by the 10×1000μs waveform. This value is measured at TA = +25°C and represents the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is the 3.0SMCJ5.0A-13 suitable for bidirectional signal line protection?
No-it is a unidirectional TVS diode with a cathode band marking; bidirectional protection requires either a dedicated bi-directional variant (e.g., 3.0SMCJ5.0CA-13) or a back-to-back pair of unidirectional devices. Using this part on AC or differential lines without polarity awareness risks permanent conduction.
How does the SMC package affect thermal performance in high-density PCB layouts?
The SMC package requires 8.00mm² copper land area per terminal for rated 3000W performance. Reduced pad size or insufficient internal copper layers causes thermal derating; Figure 1 in DS30818 shows >50% power loss at +100°C ambient unless thermal vias and plane coupling are implemented.
Does the 3.0SMCJ5.0A-13 meet AEC-Q200 stress test requirements for passive components?
While not AEC-Q200 certified out-of-box, this part is manufactured in IATF 16949-certified facilities and qualified to JEDEC standards referenced in AEC-Q; automotive-grade equivalents (e.g., 3.0SMCJ5.0AQ-13) carry full PPAP documentation and extended temperature validation.
