Product details
Overview
DM6W11AQ-13 from Diodes Incorporated is a 4600W surface-mount transient voltage suppressor (TVS) diode in DO-218 (Type E) package, designed for automotive load dump and ISO7637-2 surge protection. It features 11V reverse standoff voltage (VRWM), 12.2–13.5V breakdown voltage (VBR), 18.2V clamping voltage (VC) at 253A peak pulse current, and operates from −55°C to +175°C - deployed in engine control units and battery management systems.
For engineers reviewing the DM6W11AQ-13 datasheet, DM6W11AQ-13 pinout, DM6W11AQ-13 application, or DM6W11AQ-13 equivalent, this page delivers verified electrical parameters, thermal resistance (RθJC = 1.0°C/W), ISO16750-2 compliance status, and real-world automotive surge protection context - not generic TVS descriptions.
Technical Context
This unidirectional TVS diode uses silicon avalanche technology to clamp transients with sub-nanosecond response time. Its DO-218 package enables low thermal resistance (1.0°C/W junction-to-case) and high power handling (4600W @ 10/1000µs), supporting sustained operation up to +175°C junction temperature.
The device meets ISO 7637-2 Pulse 1, 2a, 3a, 3b and ISO 16750-2 load dump requirements. Polarity is defined by heatsink-as-anode configuration, with cathode marked by bar symbol - critical for correct PCB layout in high-energy automotive power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 4600W @ 10/1000µs - handles full automotive load dump surges without failure |
| Reverse Standoff Voltage | 11V - sets minimum operating voltage threshold before clamping activates |
| Clamping Voltage | 18.2V @ 253A - limits downstream IC voltage during worst-case surge event |
| Junction-to-Case Thermal Resistance | 1.0°C/W - enables efficient heat transfer to heatsink or copper pour |
| Operating Temperature Range | −55°C to +175°C - qualified for under-hood automotive environments |
| Max Peak Pulse Current | 253A @ 10/1000µs - defines maximum transient energy absorption capability |
| Leakage Current @ VRWM | 10µA max @ 25°C - ensures minimal standby power loss in always-on circuits |
Pinout & Package
Package: DO-218 (Type E), surface-mount, molded plastic UL 94V-0 housing; anode connected to heatsink tab, cathode marked by bar symbol on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Positive terminal / thermal path | Must be soldered to large copper area or heatsink for thermal management and current return path |
| Cathode (Bar-marked lead) | Negative terminal / clamping node | Connected to protected line (e.g., 12V rail); clamps to anode when overvoltage occurs |
Key Features
| Feature | Design Value |
|---|---|
| 4600W peak pulse power rating | Enables single-device protection against ISO16750-2 load dump (up to 120V, 100ms exponential waveform) |
| Low RθJC = 1.0°C/W | Allows >5W steady-state dissipation at TC = +25°C - supports continuous fault-tolerant operation |
| AEC-Q200 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock |
| Lead-free, halogen-free, RoHS 3 compliant | Meets automotive supply chain requirements for green manufacturing and end-of-life recycling |
| 10µA max IR @ VRWM | Minimizes quiescent current draw in always-on vehicle modules (e.g., CAN wake-up circuits) |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Battery Management System (BMS) |
|---|---|
Use Scenario: Protects 12V input stage of ECU against alternator load dump surges during ignition-off events. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between battery rail and DC-DC input filter. Use Value: Clamps 120V/100ms load dump to ≤18.2V, preventing damage to upstream PMICs and microcontrollers. |
Use Scenario: Shields BMS front-end analog sensing circuitry from ISO7637-2 Pulse 1 (inductive switch-off) transients. IC Role / Device Role / Timing Role: Primary overvoltage suppression device on main HV/LV interface board. Use Value: Absorbs 253A peak current while maintaining <10µA leakage - preserves measurement accuracy during sleep mode. |
| Advanced Driver Assistance Systems (ADAS) Camera Module | Electric Power Steering (EPS) Control Unit |
Use Scenario: Safeguards 12V supply to image sensor and ISP in rear-view camera exposed to engine bay EMI. IC Role / Device Role / Timing Role: Final-stage TVS on power entry PCB, downstream of fuse and common-mode choke. Use Value: Responds in <1ns to clamp fast-rising transients (Pulse 3a/b), preventing pixel corruption or reset events. |
Use Scenario: Protects EPS motor driver gate drivers and position sensor interfaces from inductive kickback. IC Role / Device Role / Timing Role: High-power TVS on 12V auxiliary rail feeding H-bridge pre-drivers. Use Value: Sustains 600A IFSM surge without degradation - critical for steering assist continuity during fault conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-Q | Lower PPK = 400W; SMA package; RθJC ≈ 35°C/W | Not suitable for load dump; limited to ISO7637-2 Pulse 1/2 only | Select only for cost-sensitive non-load-dump applications with lower surge energy |
| SMCJ11A-Q | PPK = 1500W; SMC package; RθJC ≈ 2.5°C/W; same VRWM | Cannot withstand full ISO16750-2 load dump; derates above +125°C | Use where space constraints prevent DO-218 mounting but higher power than SMAJ is required |
Compared with SMAJ11A-Q and SMCJ11A-Q, DM6W11AQ-13 uniquely sustains 4600W surge energy and 600A forward surge current while maintaining 1.0°C/W thermal resistance - making it the only qualified solution for under-hood load dump protection in modern 12V automotive systems.

FAQ
What is the difference between DM6W11A and DM6W11AQ-13?
DM6W11AQ-13 is the automotive-qualified version per AEC-Q200, with extended temperature range (−55°C to +175°C), enhanced process controls, and lot-level qualification testing. DM6W11A is the commercial-grade variant rated only to +150°C and not AEC-Q200 certified - unsuitable for automotive production.
Can DM6W11AQ-13 be used in bidirectional configurations?
No - DM6W11AQ-13 is a unidirectional TVS diode with anode tied to the heatsink tab. Bidirectional protection requires two devices in series opposition or a dedicated bidirectional part like DM6W11CAQ-13; using this part in reverse polarity risks permanent failure.
What PCB layout practices maximize thermal performance?
Maximize copper area connected to the anode (heatsink) tab - minimum 200 mm² of 2 oz copper with ≥4 thermal vias to inner ground planes. Keep cathode trace short and wide; avoid routing sensitive signals near the device body to minimize coupling during clamping events.
Does DM6W11AQ-13 meet ISO 10605 ESD requirements?
Yes - it complies with ISO 10605 Pulse A (150pF/330Ω) and Pulse B (330pF/330Ω) for system-level ESD immunity. Its low clamping voltage (18.2V) and fast response protect downstream CAN transceivers and LIN controllers from contact and air-gap discharge events.
