Product details
Overview
DM6W10AQ-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode in DO-218 (Type E) package, designed for automotive load-dump and ISO7637-2 surge protection. It delivers 4600W peak pulse power at 10/1000µs, features 10V reverse standoff voltage (VRWM), clamps at ≤17.0V under 271A peak pulse current, and operates from −55°C to +175°C - deployed in engine control units, body control modules, and infotainment power rails.
For engineers reviewing the DM6W10AQ-13 datasheet, DM6W10AQ-13 pinout, DM6W10AQ-13 application, or DM6W10AQ-13 equivalent, key selection criteria include ISO16750-2 Pulse A/B compliance, low thermal resistance (RθJC = 1.0°C/W), AEC-Q101 qualification, and anode-heatsink polarity configuration for high-power dissipation in constrained automotive PCB layouts.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to clamp transient overvoltages above its 11.1–12.3V breakdown range (VBR @ 5mA). Its DO-218 package integrates a thermally optimized heatsink-anode structure enabling 6W steady-state power dissipation at TC = +25°C and 4600W non-repetitive pulse handling.
It meets ISO16750-2 Load Dump (Pulse A) and ISO7637-2 Pulse 1/2a/3a/3b immunity requirements with <15µA reverse leakage at VRWM and 17.0V clamping voltage at 271A - critical for protecting 12V automotive electronics against battery-spike-induced failures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 4600W (10/1000µs waveform): sustains single-load-dump events without failure in automotive 12V systems |
| Reverse Standoff Voltage | 10V: blocks normal battery operation up to 13.5V while remaining inactive during steady-state |
| Clamping Voltage | ≤17.0V @ 271A: limits downstream IC voltage stress below 20V during worst-case transients |
| Breakdown Voltage | 11.1–12.3V @ 5mA: ensures reliable turn-on margin above VRWM for robust surge response |
| Thermal Resistance | RθJC = 1.0°C/W: enables efficient heat transfer from junction to heatsink-anode for sustained power handling |
| Operating Temperature | −55°C to +175°C: supports under-hood deployment in engine compartments and transmission control units |
| AEC-Q101 Qualified | Yes: validated for automotive-grade reliability including temperature cycling, HTRB, and surge lifetime testing |
Pinout & Package
Package: DO-218 (Type E), surface-mount molded plastic housing with heatsink-anode construction; polarity marked by bar (cathode) and circle (anode); weight ≈2.74g; UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (+) | Heatsink terminal | Primary thermal path to PCB copper pour; must be connected to large thermal pad for RθJC = 1.0°C/W performance |
| Cathode (−) | Transient current return path | Connected to protected circuit rail; carries full surge current during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| 4600W Peak Pulse Power | Handles ISO16750-2 Load Dump surges (up to 35V, 100ms) without degradation in automotive 12V systems |
| Low Clamping Ratio | VC/VRWM = 1.7: minimizes overvoltage stress on downstream MOSFETs and microcontrollers |
| AEC-Q101 Qualification | Validated for automotive use with PPAP capability and IATF 16949 manufacturing controls |
| Lead-Free & Halogen-Free | RoHS 3 compliant (<900ppm Br/Cl, <1000ppm Sb); compatible with lead-free reflow and green manufacturing |
| Low Thermal Resistance | RθJC = 1.0°C/W: allows 6W continuous dissipation at TC = +25°C with minimal derating |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Protection |
|---|---|
Use Scenario: Protects 12V supply rail of gasoline/diesel ECUs against alternator load dump and cranking transients. IC Role / Device Role / Timing Role: Primary bidirectional TVS clamp placed upstream of DC-DC converters and MCU power inputs. Use Value: Limits voltage excursion to ≤17.0V during 4600W pulses, preventing latch-up or gate oxide damage in 3.3V/5V logic supplies. |
Use Scenario: Shields CAN transceiver VCC and signal lines from coupled surges induced by nearby high-current switching (e.g., window lift motors). IC Role / Device Role / Timing Role: Secondary TVS on BCM 12V rail feeding isolated CAN power domains. Use Value: Maintains <15µA leakage at 10V VRWM to avoid quiescent current penalties in always-on vehicle networks. |
| Infotainment Head Unit Power Supply | ADAS Camera Module Input Protection |
Use Scenario: Guards USB-C PD and display power rails in head units exposed to battery disconnect/reconnect events. IC Role / Device Role / Timing Role: Front-end TVS on fused 12V input before buck regulators and PMICs. Use Value: Withstands 600A IFSM (8.3ms half-sine) without bond wire fusing, ensuring system-level surge resilience. |
Use Scenario: Safeguards 12V input of rear-view or surround-view cameras mounted near chassis ground points. IC Role / Device Role / Timing Role: Single-point TVS on camera module power entry with heatsink-anode thermal anchoring. Use Value: Operates up to +175°C ambient, enabling direct mounting on metal housings without thermal derating loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC package; 400W PPK; RθJC ≈ 45°C/W; no AEC-Q101 qualification | Limited to non-automotive industrial or consumer power rails; unsuitable for load-dump immunity | Select only for cost-sensitive, non-automotive designs where 4600W surge rating is unnecessary |
| SMCJ10A | DO-214AB package; 1500W PPK; RθJC ≈ 10°C/W; AEC-Q101 qualified but lower pulse rating | Acceptable for ISO7637-2 Pulse 1/2a only; cannot meet ISO16750-2 Load Dump (Pulse A) | Choose when space constraints prevent DO-218 mounting but AEC-Q101 compliance is mandatory |
Compared with SMAJ10A and SMCJ10A, DM6W10AQ-13 uniquely combines AEC-Q101 qualification, 4600W pulse rating, and 1.0°C/W thermal resistance - making it the only option capable of meeting full ISO16750-2 Load Dump requirements in thermally constrained automotive modules.

FAQ
What is the maximum clamping voltage of DM6W10AQ-13 at rated peak pulse current?
The maximum clamping voltage VC is 17.0V at IPP = 271A for a 10/1000µs waveform, measured per JEDEC standards. This value is guaranteed across the full operating temperature range (−55°C to +175°C) and ensures downstream components remain within safe voltage margins during surge events.
Is DM6W10AQ-13 suitable for 24V commercial vehicle applications?
No - DM6W10AQ-13 is specified for 12V automotive systems with VRWM = 10V and VBR min = 11.1V. For 24V platforms, Diodes offers DM6W24AQ-13 (VRWM = 24V, VC ≤ 38.9V @ 118A), which maintains identical DO-218 packaging and AEC-Q101 qualification.
How should the heatsink-anode be implemented on the PCB for optimal thermal performance?
The anode must be soldered to a minimum 250 mm² copper thermal pad with ≥4 thermal vias (0.3mm diameter, filled) connecting to internal ground planes. Per Diodes' layout guidelines, this achieves RθJC = 1.0°C/W and prevents junction overheating during 4600W pulses.
Does DM6W10AQ-13 require external series impedance for effective protection?
No - it functions as a shunt protector and requires no series resistor. However, placement must be within 20mm of the protected IC's power pin, with short, wide traces to minimize inductance; adding a 100nF ceramic capacitor in parallel improves high-frequency transient suppression.
