Product details
Overview
3.0SMCJ10AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) designed for primary overvoltage protection on DC power rails and signal lines. It features a 10V reverse standoff voltage (VRWM), 17.0V maximum clamping voltage (VC) at 176.5A peak pulse current, and IEC-61000-4-2 ESD immunity of 30kV (air/contact). It is used in automotive infotainment power inputs to absorb load dump and ISO 7637-2 transients.
For engineers reviewing the 3.0SMCJ10AQ-13 datasheet, 3.0SMCJ10AQ-13 pinout, 3.0SMCJ10AQ-13 application, or 3.0SMCJ10AQ-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability under 10/1000μs waveform, thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device: when reverse voltage exceeds its breakdown threshold (11.1–12.27V), it avalanches into low-impedance conduction to shunt surge energy away from downstream circuitry. Its glass-passivated silicon die ensures stable breakdown characteristics and low leakage (<5.0μA at VRWM).
The device is rated for 3000W peak pulse power (10×1000μs waveform), supports 300A non-repetitive forward surge (8.3ms half-sine), and maintains operation across –55°C to +150°C junction temperature - enabling use in under-hood automotive environments without derating below +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10/1000μs surges up to this level without failure |
| Reverse Standoff Voltage (VRWM) | 10.0V - maximum continuous DC voltage before significant leakage begins |
| Clamping Voltage (VC) | 17.0V @ 176.5A - limits transient voltage seen by protected ICs during surge events |
| Breakdown Voltage (VBR) | 11.1–12.27V @ 1.0mA - defines precise avalanche initiation range for predictable triggering |
| ESD Rating | 30kV air/contact per IEC-61000-4-2 - protects against human-handling electrostatic discharge |
| Operating Temperature | –55°C to +150°C - qualified for under-hood automotive and industrial power supply applications |
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 (banded end) | Surge current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage |
| Anode | Reference/ground return | Typically tied to system ground plane; completes low-inductance surge path |
Key Features
| Feature | Design Value |
|---|---|
| 3000W peak pulse power | Enables robust protection against ISO 7637-2 Pulse 5a (load dump) in 12V automotive systems |
| Glass-passivated die construction | Ensures stable VBR tolerance and long-term reliability under thermal cycling |
| Lead-free, RoHS-compliant finish | Meets automotive and industrial environmental compliance requirements without SnPb reflow concerns |
| IEC-61000-4-2 ESD rating | Eliminates need for secondary ESD protection on board-level interfaces |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-13-F | 600W rating, SMB package, same VRWM and VC but lower IPP (88.2A) | Insufficient for ISO 7637-2 Pulse 5a; suitable only for IEC-61000-4-4/5 surges | Select when space-constrained layouts preclude SMC and surge energy is ≤600W |
| 1.5SMC10A-Q | 1500W rating, same SMC package, higher VC (18.2V), lower PPK | Marginally adequate for 12V automotive; fails 3000W validation tests | Choose only for cost-sensitive non-automotive applications where 1500W suffices |
Compared with SMBJ10A-13-F and 1.5SMC10A-Q, the 3.0SMCJ10AQ-13 delivers 2× and 2× higher peak power handling respectively, enabling single-device compliance with automotive load dump standards - critical where PCB area allows SMC footprint and reliability under repeated surge stress is mandatory.

FAQ
What is the difference between 3.0SMCJ10AQ-13 and standard 3.0SMCJ10A-13?
The "Q" suffix denotes AEC-Q101 qualification: this variant undergoes additional stress testing (HTGB, HTRB, TCT, UHAST) and is manufactured in IATF 16949-certified facilities. It includes PPAP documentation support and change control per automotive requirements - unlike the commercial-grade -13 version.
Can 3.0SMCJ10AQ-13 be used in bidirectional configurations?
No - the "Q" suffix part is unidirectional only, indicated by its cathode band marking. Bidirectional variants (e.g., 3.0SMCJ10CAQ-13) have no polarity marker and symmetric breakdown in both directions. Using this part in reverse-biased AC applications would result in immediate conduction and failure.
What is the minimum PCB pad size required for reliable thermal performance?
Per Diodes' datasheet, the recommended land pattern uses 8.00 mm² copper pads (e.g., 2.0mm × 4.0mm) per terminal, 0.013mm thick, to sustain full 3000W pulse rating. Smaller pads cause thermal derating - at 4.0 mm², peak power drops to ~1800W per Figure 1.
Does this TVS require a series impedance for optimal clamping performance?
Yes - a low-inductance series resistor or ferrite bead (typically 0.5–2Ω) between the TVS anode and system ground improves clamping response by limiting di/dt and reducing ground bounce. Without it, parasitic inductance can raise effective clamping voltage by up to 20% during fast transients.
