Product details
Overview
3.0SMCJ64AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) designed for primary overvoltage protection in automotive power rails and DC input stages. It features a 64V reverse standoff voltage (VRWM), 71.1–78.6V breakdown voltage (VBR), 103V maximum clamping voltage (VC) at 29.1A peak pulse current (IPP), and IEC-61000-4-2 ESD immunity up to 30kV (air/contact). It is AEC-Q101 qualified and used in 12V/24V vehicle subsystems including body control modules and infotainment power supplies.
For engineers reviewing the 3.0SMCJ64AQ-13 datasheet, 3.0SMCJ64AQ-13 pinout, 3.0SMCJ64AQ-13 application, or 3.0SMCJ64AQ-13 equivalent, key selection criteria include clamping voltage margin relative to system rail tolerance, peak pulse current handling under ISO 7637-2 Pulse 1/2b stress, thermal derating above +25°C ambient, and SMC package solder joint reliability per J-STD-020 Level 1 moisture sensitivity.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its specified breakdown range (71.1–78.6V at 1mA test current). Its glass-passivated silicon junction ensures stable VBR tolerance and low leakage (<5µA at VRWM), critical for low-power always-on circuits.
It responds to transients with sub-nanosecond turn-on time and clamps energy within a 10×1000µs waveform envelope, delivering 3000W peak pulse power dissipation without degradation. The device is rated for continuous operation from –55°C to +150°C junction temperature and supports automotive PPAP compliance via IATF 16949 manufacturing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single high-energy transients like ISO 7637-2 Pulse 5a without failure |
| Reverse Standoff Voltage (VRWM) | 64V - maximum continuous DC operating voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 71.1–78.6V @ 1mA - defines precise avalanche initiation threshold for predictable clamping onset |
| Max Clamping Voltage (VC) | 103V @ 29.1A IPP - limits downstream voltage stress during worst-case surge events |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling electrostatic discharge |
| Operating Temperature | –55°C to +150°C - enables deployment in engine bay, battery management, and ADAS sensor modules |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability with change control, PPAP support, and IATF 16949 manufacturing |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating; weight ≈ 0.21g; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked band) | Transient current sink node | Connected to protected line (e.g., 24V rail); conducts avalanche current to ground during overvoltage |
| Anode | Reference/ground return path | Connected to system ground plane; completes clamping loop with minimal inductance for fast response |
Key Features
| Feature | Design Value |
|---|---|
| 3000W peak pulse power | Enables robust protection against severe load dump (ISO 7637-2 Pulse 5a) without derating or parallel devices |
| Glass-passivated die | Ensures long-term VBR stability and low parametric drift across temperature and lifetime stress |
| Lead-free, RoHS 3 & "Green" compliant | Meets automotive environmental requirements: <900ppm Br, <900ppm Cl, <1000ppm Sb |
| IEC-61000-4-2 ESD immunity | Eliminates need for secondary ESD protection on board-level interfaces exposed to user access points |
| Uni-directional configuration | Prevents unwanted conduction during normal forward-biased operation in DC power paths |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protects 12V/24V supply inputs of BCM microcontrollers and CAN transceivers from load dump and jump-start surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed directly at connector entry point before LDO regulators. Use Value: Limits rail voltage to ≤103V during ISO 7637-2 Pulse 5a (100V/350ms), preventing regulator latch-up and MCU brownout. |
Use Scenario: Shields 24V digital input channels of programmable logic controllers from field-wiring induced transients. IC Role / Device Role / Timing Role: Front-end transient suppressor mounted adjacent to terminal block, before optocoupler input stage. Use Value: Clamps 1kV/500Ω ring wave surges to <103V, preserving optocoupler CTR and enabling >100,000-cycle surge endurance. |

Use Scenario: Guards 12V auxiliary power rail of OBC control boards against battery reversal and alternator ripple spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between fuse output and buck converter input, with cathode to rail. Use Value: Withstands 3000W pulses while maintaining <5µA leakage at 64V, minimizing standby current loss in always-on systems. |
Use Scenario: Secures 12V power input of cellular/V2X telematics modules mounted in vehicle cabins. IC Role / Device Role / Timing Role: First-line defense against ESD events from USB/RS232 connectors and conducted noise from infotainment systems. Use Value: Delivers 30kV IEC-61000-4-2 contact discharge suppression without requiring additional TVS arrays or ferrite beads. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A | Lower peak power (400W), SMA package, same VRWM/VBR range | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy surges like ESD or switching noise | Select only for cost-sensitive non-automotive applications where 3000W surge immunity is unnecessary |
| 1.5SMCJ64A | Same 3000W rating but non-automotive grade; no AEC-Q101 qualification or PPAP support | Lacks automotive change control, traceability, and IATF 16949 manufacturing documentation | Acceptable for industrial prototypes or non-safety-critical consumer designs; not for production automotive use |
Compared with SMAJ64A and 1.5SMCJ64A, the 3.0SMCJ64AQ-13 uniquely combines AEC-Q101 qualification, 3000W clamping capability, and SMC package thermal robustness-making it the only choice for production automotive power rail protection requiring full ISO 7637-2 compliance.

FAQ
What is the meaning of the 'Q' suffix in 3.0SMCJ64AQ-13?
The 'Q' suffix denotes AEC-Q101 qualification, confirming that this part meets the stress-test requirements for automotive discrete semiconductors-including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. It also signifies PPAP readiness and manufacturing in IATF 16949-certified facilities, unlike standard industrial variants.
Can 3.0SMCJ64AQ-13 be used in bidirectional signal lines?
No. This is a unidirectional TVS diode with a cathode band marking; it conducts only when reverse-biased beyond its breakdown voltage. For bidirectional data lines (e.g., CAN, LIN), a bidirectional variant such as 3.0SMCJ64CA-13 must be used-its symmetrical VBR allows clamping of both positive and negative transients.
How does thermal derating affect its 3000W rating?
The 3000W peak pulse power is specified at TA = +25°C. Above this temperature, power handling decreases per Figure 1 in DS30818: at +85°C ambient, it is derated to ~75% (2250W); at +125°C, to ~45% (1350W). Layout with ≥8mm² copper pad area is required to maintain effective heat dissipation during surge events.
Is the SMC package compatible with standard reflow profiles?
Yes. The SMC package is rated for moisture sensitivity level 1 (MSL-1), meaning it can be stored indefinitely at ≤30°C/60% RH and processed using standard lead-free reflow profiles (peak 260°C, 20–40 sec above 217°C) without baking. Matte tin-plated leads ensure reliable solder wetting per MIL-STD-202, Method 208.
