Product details
Overview
3.0SMCJ6.5AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in automotive power rails and industrial DC inputs. It features a 6.5V reverse standoff voltage (VRWM), 7.22–7.98V breakdown voltage (VBR) at 10mA, and clamps transients to ≤11.2V at 267.9A peak pulse current (IPP), meeting AEC-Q101 requirements for automotive-grade reliability.
For engineers reviewing the 3.0SMCJ6.5AQ-13 datasheet, 3.0SMCJ6.5AQ-13 pinout, 3.0SMCJ6.5AQ-13 application, or 3.0SMCJ6.5AQ-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, IEC-61000-4-2 ESD robustness (30kV air/30kV contact), and SMC package thermal performance under repetitive surge conditions.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated die construction, enabling fast response (<1ps) to ESD and lightning-induced surges. Its unidirectional configuration provides low-leakage (<500µA at VRWM) and precise clamping during positive-polarity transients on DC supply lines.
The device complies with AEC-Q101 stress tests including temperature cycling, high-temperature operating life, and surge robustness, and is rated for continuous operation from –55°C to +150°C junction temperature. Its SMC package supports 3000W peak pulse power dissipation per the 10×1000µs waveform standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10×1000µs transients without failure in automotive load-dump or ISO 7637-2 pulse 5a scenarios |
| Reverse Standoff Voltage | 6.5V - maximum continuous DC voltage before significant leakage; sets minimum system rail compatibility |
| Breakdown Voltage | 7.22–7.98V @ 10mA - defines onset of avalanche conduction; ensures reliable triggering above nominal rail |
| Clamping Voltage | ≤11.2V @ 267.9A - limits downstream voltage stress during worst-case surge; critical for 12V system IC survival |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling and cable-discharge events |
| Operating Temperature | –55°C to +150°C - qualified for under-hood automotive environments and industrial enclosures |
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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; forms cathode-to-rail clamping topology |
| Cathode | Protected line terminal | Connected to input rail (e.g., battery+); conducts surge current to ground when voltage exceeds VRWM |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 qualified - enables use in engine control units, ADAS sensors, and body electronics without additional qualification effort |
| Clamping ratio | VC/VRWM = 1.72 - low ratio ensures minimal overvoltage margin; preserves headroom for 12V system ICs with 13.2V absolute max ratings |
| Leakage control | ≤500µA @ 6.5V - prevents excessive quiescent current drain in always-on vehicle modules |
| Thermal robustness | 150°C max junction temperature - supports placement near heat-generating components without derating |
Applications
| Automotive Body Control Module | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting LIN bus power rail and microcontroller VDD from load dump and jump-start transients in door module ECUs. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between battery feed and LDO input; responds within picoseconds to suppress >100V spikes. Use Value: Enables compliance with ISO 16750-2 pulse 5a (load dump) by limiting rail voltage to <11.2V, preventing LDO dropout or MCU latch-up. |
Use Scenario: Safeguarding 24V DC input terminals of programmable logic controllers against field-wiring faults and inductive kickback. IC Role / Device Role / Timing Role: Front-end TVS in multi-stage protection network; absorbs bulk surge energy before downstream MOVs and GDTs. Use Value: Handles 3000W peak pulses without degradation, extending protection circuit lifetime in factory automation environments with frequent motor switching. |
| Automotive Infotainment Power Supply | Telecom Remote Radio Unit |
Use Scenario: Shielding USB-C PD controller and display driver power inputs from battery-line transients during vehicle start-stop cycles. IC Role / Device Role / Timing Role: Unidirectional clamp on 5V/12V rails; activated only during positive overvoltage events to avoid interfering with normal bidirectional signaling. Use Value: Maintains <500µA leakage at 6.5V, eliminating standby current penalty while delivering sub-11.2V clamping for sensitive SoCs. |
Use Scenario: Protecting 48V DC power interface of 5G remote radio heads from lightning-induced surges on outdoor power-over-ethernet (PoE++) feeds. IC Role / Device Role / Timing Role: First-line transient suppressor mounted directly at connector entry point; coordinates with secondary TVS array for staged energy handling. Use Value: Withstands 267.9A peak current per 10×1000µs waveform, reducing need for oversized PCB traces and enabling compact outdoor enclosure designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | 600W peak power, same VRWM and VBR range, SMB package | Lower surge capacity; suitable only for non-load-dump applications like ESD-only protection | Select when board space is constrained and surge energy is limited to IEC-61000-4-2 or ISO 10605 levels |
| 1.5SMCJ6.5A | 1500W peak power, identical electrical specs, same SMC package | Half the pulse power rating; insufficient for ISO 7637-2 pulse 5a compliance | Choose only for cost-sensitive industrial controls where full 3000W capability is not required |
Compared with SMBJ6.5A and 1.5SMCJ6.5A, the 3.0SMCJ6.5AQ-13 delivers double the surge energy handling of the 1.5kW variant and five times that of the SMB variant-making it the sole option qualified for automotive load-dump immunity without external parallel staging.

FAQ
What is the meaning of the 'Q' suffix in 3.0SMCJ6.5AQ-13?
The 'Q' suffix denotes AEC-Q101 qualification, confirming the device has passed stress tests for automotive applications-including temperature cycling, high-temperature operating life, and surge robustness. It is manufactured in IATF 16949-certified facilities and supports PPAP documentation for Tier 1 automotive suppliers.
Can 3.0SMCJ6.5AQ-13 be used in bidirectional signal lines?
No-this is a unidirectional TVS diode with a cathode band marking. It clamps only positive transients on the cathode side relative to anode (ground). For bidirectional protection (e.g., data lines), a bi-directional variant such as 3.0SMCJ6.5CA-13 must be selected instead.
How does its clamping voltage compare to competing 6.5V TVS devices?
At 267.9A IPP, its maximum clamping voltage is 11.2V-among the lowest in the 3000W SMC class. Competing devices like ON Semiconductor's SMAJ6.5A specify 11.5V, resulting in 0.3V higher stress on protected ICs during worst-case surges.
Is lead-free and RoHS compliance verified for this part?
Yes-3.0SMCJ6.5AQ-13 features matte tin-plated leads, conforms to EU RoHS directives 2011/65/EU and 2015/863/EU, and is halogen- and antimony-free ("Green" per Diodes' definition: <900ppm Br, <900ppm Cl, <1000ppm Sb).
