Product details
Overview
DM6W24AQ-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 features 24 V reverse standoff voltage (VRWM), 38.9 V max clamping voltage (VC) at 118 A peak pulse current (IPP), and 4600 W peak pulse power (10/1000 µs). Used in engine control units and body electronics to safeguard microcontrollers and CAN transceivers against high-energy transients.
For engineers reviewing the DM6W24AQ-13 datasheet, DM6W24AQ-13 pinout, DM6W24AQ-13 application, or DM6W24AQ-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VCC, thermal resistance (RθJC = 1.0 °C/W), AEC-Q101 qualification status, and DO-218 heatsink-anode polarity configuration for PCB layout and thermal management.
Technical Context
This unidirectional TVS diode operates with anode-connected heatsink polarity, enabling low-inductance mounting directly to copper planes for optimal thermal dissipation during 10 ms exponential load-dump events per ISO16750-2 Pulse 5a. Its breakdown voltage (VBR = 26.7–29.5 V @ 5 mA) ensures reliable triggering before downstream component overvoltage.
The device sustains 600 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and maintains <15 µA reverse leakage at VRWM up to +175 °C junction temperature, supporting under-hood deployment in modern 12 V automotive systems with stringent thermal and reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - Maximum continuous reverse operating voltage before clamping begins; sets system-level overvoltage threshold for 12 V battery architectures. |
| VBR min/max | 26.7 / 29.5 V @ 5 mA - Confirmed breakdown range ensures predictable turn-on with margin above VRWM for noise immunity. |
| VC @ IPP | 38.9 V @ 118 A (10/1000 µs) - Clamping voltage defines worst-case stress on protected ICs; critical for 3.3 V or 5 V logic rail survivability. |
| PPK | 4600 W - Peak pulse power rating validated for ISO16750-2 load-dump simulation; enables single-device protection without parallel staging. |
| RθJC | 1.0 °C/W - Low junction-to-case thermal resistance allows direct heatsink coupling; supports >6 W steady-state dissipation at TC = +25 °C. |
| TJ range | −55 to +175 °C - Full automotive temperature range compliance; qualified for under-hood ECU and transmission control module placement. |
Pinout & Package
DO-218 (Type E) surface-mount package with integrated heatsink tab; polarity marked by bar symbol denoting cathode and circle indicating anode - heatsink tab is electrically connected to anode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Positive surge return path | Electrically tied to case; must be soldered to large copper pour for thermal conduction and low-inductance grounding in load-dump paths. |
| Cathode (Top Surface Lead) | Surge current input node | Connected to protected line (e.g., battery rail); clamps to anode when transient exceeds VRWM, diverting energy to chassis ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use with PPAP capability and IATF 16949 manufacturing; eliminates requalification risk in Tier 1 BOMs. |
| ISO16750-2 & ISO7637-2 compliant | Passes Pulse 5a (load dump) and Pulse 1/2a/3a/3b testing without derating; reduces need for external filtering or staged protection. |
| Lead-free, halogen-free "Green" construction | Meets RoHS 3 (2015/863/EU) and automotive green standards (<900 ppm Br/Cl, <1000 ppm Sb); supports global vehicle homologation. |
| Low RθJC (1.0 °C/W) | Enables >90% of rated 4600 W pulse power to be dissipated through the heatsink tab, minimizing PCB trace heating and thermal runaway risk. |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) Battery Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T (Vishay) | Same VRWM (24 V), but lower PPK (400 W), DO-214AC package, RθJC = 45 °C/W. | Limited to low-energy transients; unsuitable for ISO16750-2 load-dump without parallel devices. | Select only for cost-sensitive non-automotive 12 V systems with verified <1 kW surge profiles. |
| TPSMD24 (Texas Instruments) | 24 V VRWM, 4000 W PPK, DO-218AB package, but not AEC-Q101 qualified; RθJC = 1.2 °C/W. | Lacks PPAP documentation and IATF 16949 traceability; requires full requalification for automotive production. | Acceptable for prototyping or industrial designs where automotive certification is not mandated. |
Compared with SMAJ24A-E3/57T and TPSMD24, DM6W24AQ-13 uniquely combines AEC-Q101 qualification, 4600 W pulse rating, and 1.0 °C/W thermal resistance in a single DO-218 device-enabling simplified, high-reliability load-dump protection without derating or secondary components.

FAQ
What is the maximum clamping voltage of DM6W24AQ-13 under standard test conditions?
The maximum clamping voltage (VC) is 38.9 V at 118 A peak pulse current using a 10/1000 µs waveform, measured per IEC 61000-4-5. This value is guaranteed across the full −55 °C to +175 °C junction temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Is DM6W24AQ-13 suitable for bidirectional surge protection?
No - DM6W24AQ-13 is a unidirectional TVS diode with anode-connected heatsink polarity. It conducts only during positive transients on the cathode relative to anode. For bidirectional protection (e.g., data lines), a symmetric dual-diode array or separate complementary device is required.
How does the DO-218 package's heatsink-anode configuration impact PCB layout?
The anode is internally bonded to the metal heatsink tab, requiring direct soldering to a large copper area (≥250 mm² recommended) for thermal performance. Cathode connects via top-surface lead; routing must minimize loop inductance between cathode trace and heatsink plane to preserve clamping speed and prevent voltage overshoot.
Does DM6W24AQ-13 require derating at elevated ambient temperatures?
Yes - power derating follows Figure 1 in DS41001: PM(AV) drops linearly from 6.0 W at TC = +25 °C to 0 W at TC = +125 °C. At +100 °C case temperature, maximum continuous power is 2.4 W. Peak pulse power remains 4600 W if heatsink maintains TC ≤ +25 °C during transient.
