Product details
Overview
3.0SMCJ5.0AQ-13 from Diodes Incorporated is a unidirectional 5.0V standoff, 3000W peak pulse power transient voltage suppressor (TVS) diode in SMC package, rated for 9.2V clamping at 326.1A peak pulse current, AEC-Q101 qualified, and designed to protect automotive power and signal lines against ISO7637-2 Pulse 1/2a/3a/3b transients and ISO10605 ESD events.
For engineers reviewing the 3.0SMCJ5.0AQ-13 datasheet, 3.0SMCJ5.0AQ-13 pinout, 3.0SMCJ5.0AQ-13 application, or 3.0SMCJ5.0AQ-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, peak pulse current capability under 10/1000μs waveform, AEC-Q101 qualification status, and SMC package thermal performance on 8mm² copper land.
Technical Context
This TVS operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds 5.0V standoff (VRWM), with breakdown occurring between 6.40V–7.07V at 10mA test current. It delivers 3000W peak pulse power per 10×1000μs waveform and sustains 300A non-repetitive forward surge current under 8.3ms half-sine conditions.
Designed for automotive-grade reliability, it features -55°C to +175°C operating junction temperature, RoHS-compliant matte tin plating, and IATF16949-certified manufacturing. Its 9.2V clamping voltage at 326.1A ensures robust protection of 5V rail components such as CAN transceivers, microcontrollers, and sensor interfaces.
Key Specifications

| Lead-Free & Halogen-Free | Meets RoHS 3 and automotive green chemistry requirements (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Engine Control Unit (ECU) Power Input | CAN FD Transceiver Interface |
|---|---|
Use Scenario: 12V battery-supplied ECU subjected to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor. Use Value: Clamps transients to ≤9.2V, preventing damage to 5V LDOs and MCU VDD pins during ISO7637-2 Pulse 1 and Pulse 2a events. |
Use Scenario: CAN FD node exposed to ESD and coupled noise on differential bus lines. IC Role / Device Role / Timing Role: TVS mounted across CANH–CANL or from each line to chassis ground. Use Value: Absorbs ±30kV contact discharge (ISO10605) while maintaining signal integrity due to low capacitance and fast response. |
| Automotive Camera Module Power Rail | Body Control Module (BCM) Sensor Inputs |
Use Scenario: 5V-powered image sensor and ISP subjected to ignition-induced transients. IC Role / Device Role / Timing Role: TVS installed at camera module PCB edge, upstream of DC-DC converter. Use Value: Limits voltage excursion to 9.2V during 10/1000μs surges, preserving pixel data integrity and avoiding reset faults. |
Use Scenario: BCM analog inputs (e.g., ambient light, rain sensor) connected to exterior harnesses. IC Role / Device Role / Timing Role: TVS placed at connector entry point, referenced to local ground plane. Use Value: Suppresses induced spikes from nearby high-current loads (e.g., wiper motor), ensuring ADC accuracy and reducing false triggers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-Q | 600W peak power, same 5.0V VRWM and 9.2V VC, but lower IPP (65.2A) | Suitable only for lower-energy transients (e.g., ISO10605 only); insufficient for ISO7637-2 Pulse 1 | Select when space-constrained layout requires SMB package and surge severity is limited to ESD-level events. |
| 1.5SMCJ5.0A | 1500W peak power, identical VRWM/VC/IPP specs scaled by 0.5×, same SMC package | Lower energy handling limits use to infotainment or interior modules not exposed to engine bay transients | Choose where cost optimization is critical and full 3000W immunity is not required by system-level test plan. |
Compared with SMBJ5.0A-Q and 1.5SMCJ5.0A, the 3.0SMCJ5.0AQ-13 uniquely supports full ISO7637-2 compliance at engine-bay severity levels while retaining SMC thermal mass and AEC-Q101 traceability-making it the only option among the three qualified for powertrain-critical 5V rail protection.

FAQ
What is the difference between 3.0SMCJ5.0AQ-13 and 3.0SMCJ5.0A-13?
The "Q" suffix denotes AEC-Q101 qualification and PPAP capability, with manufacturing in IATF16949-certified facilities. The non-Q version lacks automotive-specific qualification documentation, change control, and traceability-making it unsuitable for production automotive designs despite identical electrical specs.
Can 3.0SMCJ5.0AQ-13 be used for bidirectional protection?
No-it is unidirectional, as confirmed by absence of "C" in the part number and marking code "HDE". For bidirectional 5V protection, use 3.0SMCJ5.0CAQ-13 (marked "DHS"), which provides symmetrical clamping for AC-coupled or floating lines.
What PCB layout practices maximize thermal performance?
Mount on ≥8.00mm² copper land areas per terminal, use thermal vias under pads, and avoid narrow traces. Derating begins above +25°C ambient-consult Figure 1 for 75% power at +85°C and 50% at +125°C to ensure long-term reliability.
Is this device compliant with China RoHS and REACH?
Yes-Diodes Incorporated confirms full compliance with China RoHS II (GB/T 26572-2011) and REACH SVHC thresholds. Full substance declarations and test reports are available via Diodes' Quality Portal using document DS40742 Rev. 12-2.
