Product details
Overview
3.0SMCJ8.0A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features an 8.0V reverse standoff voltage (VRWM), 8.89–9.83V breakdown voltage (VBR) at 1.0mA test current, 13.6V maximum clamping voltage (VC) at 220.6A peak pulse current (IPP), and IEC-61000-4-2 ESD rating of 30kV (air/contact). It is used in automotive infotainment power inputs to suppress load dump and ISO 7637-2 transients.
For engineers reviewing the 3.0SMCJ8.0A-13 datasheet, 3.0SMCJ8.0A-13 pinout, 3.0SMCJ8.0A-13 application, or 3.0SMCJ8.0A-13 equivalent, this page delivers verified electrical parameters, SMC package mechanical data, clamping performance under 10/1000μs surge, thermal derating behavior, and direct alternatives with documented VBR/VC/IPP trade-offs - all critical for robust front-end protection design.
Technical Context
This TVS operates as a unidirectional avalanche clamp: it remains high-impedance below 8.0V VRWM, triggers at 8.89–9.83V VBR, and limits transient energy by shunting up to 220.6A (10×1000μs waveform) while holding voltage ≤13.6V. Its glass-passivated die ensures stable breakdown and low leakage (<50μA at VRWM).
Thermally rated for -55°C to +150°C junction operation, it supports automotive-grade reliability with JEDEC-compliant construction and meets AEC-Q200 stress requirements when specified with Q-suffix variants. The SMC package enables 3000W peak pulse dissipation on standard PCB land patterns (8.00mm² copper area).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs surges without failure under defined mounting conditions |
| Reverse Standoff Voltage | 8.0V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 8.89–9.83V @ 1.0mA - precise avalanche onset range enabling predictable trigger margin above VRWM |
| Clamping Voltage | 13.6V @ 220.6A - maximum voltage seen by protected circuit during worst-case transient |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling electrostatic discharge |
| Junction Temp Range | -55°C to +150°C - supports under-hood automotive and industrial ambient environments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with matte tin-plated leads; UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020; weight ≈0.21g. Cathode band denotes polarity for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes clamping loop during overvoltage event |
| Cathode | High-side connection point | Connected to protected line (e.g., 12V rail); carries full surge current into anode during clamping |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Ensures stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| 3000W peak pulse rating | Enables protection against severe transients like ISO 7637-2 Pulse 5a (load dump) in 12V systems |
| Low clamping ratio (VC/VRWM = 1.7) | Minimizes voltage overshoot on protected ICs, reducing risk of latch-up or damage in downstream logic |
| RoHS-compliant & halogen-free | Meets automotive and industrial environmental compliance mandates without compromising surge performance |
Applications
| Automotive Power Input | Industrial PLC I/O Port |
|---|---|
Use Scenario: 12V battery-fed infotainment head unit exposed to load dump (ISO 7637-2 Pulse 5a) and jump-start surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converter input. Use Value: Limits transient voltage to ≤13.6V, preventing damage to 16V-rated input capacitors and controller ICs. |
Use Scenario: 24V digital input module receiving signals from field sensors in factory automation. IC Role / Device Role / Timing Role: Interface-level TVS protecting optocoupler input and microcontroller GPIO. Use Value: Absorbs 220.6A surges from inductive switching noise while maintaining <50μA leakage at 24V nominal. |
| Telecom PoE PSE Port | Medical Equipment Power Entry |
Use Scenario: Power Sourcing Equipment (PSE) port delivering IEEE 802.3af/at power over Ethernet. IC Role / Device Role / Timing Role: Secondary surge suppression stage after primary gas discharge tube (GDT). Use Value: Provides fast-response clamping (ns-scale) to complement GDT's slower action, limiting let-through voltage to safe levels for PHY ICs. |
Use Scenario: AC/DC adapter input stage in Class II medical devices requiring reinforced isolation and surge immunity. IC Role / Device Role / Timing Role: Line-to-ground transient suppressor on secondary-side DC bus. Use Value: Meets IEC 60601-1 Ed. 3.2 surge withstand requirements (±2kV line-earth) with validated 13.6V clamping ceiling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Lower peak power (600W), same VRWM/VBR/VC, SMB package (smaller footprint, lower thermal mass) | Suitable for lower-energy transients (e.g., IEC 61000-4-5 Level 3) but not ISO 7637-2 Pulse 5a | Select when board space is constrained and surge energy is ≤600W; verify thermal derating at elevated ambient temperatures. |
| 1.5SMCJ8.0A | Same SMC package, lower peak power (1500W), identical VRWM/VBR/VC specs | Valid for moderate transients (e.g., EFT bursts, lower-current load dumps) but insufficient for full 3000W events | Choose where cost optimization is prioritized and worst-case surge energy is confirmed ≤1500W via system-level testing. |
Compared with SMBJ8.0A and 1.5SMCJ8.0A, the 3.0SMCJ8.0A-13 delivers double the surge energy handling of the latter and five times that of the former - making it the only option among the three qualified for automotive load dump protection without parallel staging.

This device belongs to Diodes' 3.0SMCJ series of high-power TVS diodes, engineered specifically for demanding transient suppression in automotive, industrial, and communications infrastructure where robustness against ISO 7637-2, IEC 61000-4-5, and ESD events is mandatory.
FAQ
What is the maximum clamping voltage of the 3.0SMCJ8.0A-13 under a 10×1000μs surge?
The maximum clamping voltage is 13.6V when subjected to its rated peak pulse current of 220.6A, measured per the 10×1000μs waveform defined in Figure 2 of DS30818. This value is guaranteed across the full operating temperature range and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events.
Is the 3.0SMCJ8.0A-13 suitable for bidirectional signal line protection?
No - the "A" suffix denotes unidirectional configuration with a cathode band; it conducts only in reverse breakdown. For bidirectional protection (e.g., RS-485, USB D+/D−), the "CA" variant (e.g., 3.0SMCJ8.0CA-13) must be used, which has symmetrical breakdown in both polarities and no polarity marking.
How does the 3.0SMCJ8.0A-13 perform at elevated ambient temperatures?
Its peak pulse power derates linearly above +25°C: at +100°C ambient, it retains ~65% of rated 3000W capability per Figure 1. This requires careful PCB layout with ≥8.00mm² copper pad area and thermal vias to maintain junction temperature within -55°C to +150°C limits during surge events.
Does this part meet AEC-Q200 qualification?
The base 3.0SMCJ8.0A-13 is not AEC-Q200 qualified; however, Diodes offers automotive-grade equivalents with "Q" suffix (e.g., 3.0SMCJ8.0AQ-13), manufactured in IATF 16949-certified facilities and tested to AEC-Q200 stress requirements. These variants are listed on Diodes' automotive products webpage.
