Product details
Overview
DM6W16AQ-13 from Diodes Incorporated is a DO-218 surface-mount transient voltage suppressor (TVS) diode designed for automotive load-dump and ISO7637-2 surge protection. It features a 16 V reverse standoff voltage (VRWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage (VC) at 177 A peak pulse current, and 4600 W peak pulse power dissipation (10/1000 µs). It is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C.
For engineers reviewing the DM6W16AQ-13 datasheet, DM6W16AQ-13 pinout, DM6W16AQ-13 application, or DM6W16AQ-13 equivalent, this device is selected for high-energy transient suppression in 12 V automotive power rails-particularly where low clamping voltage, high IFSM (600 A), and thermal robustness (RθJC = 1.0 °C/W) are critical for protecting ECUs, body controllers, and ADAS sensors.
Technical Context
This unidirectional TVS diode operates with anode-connected heatsink polarity and is optimized for fast response to load-dump transients (ISO16750-2 Pulse 5a) and coupled surges (ISO7637-2 Pulse 1, 2a, 3a/b). Its DO-218 package enables low thermal resistance and high power handling without discrete heat sinking.
The device exhibits 150 µA max reverse leakage at VRWM and only 250 µA at TJ = +175 °C, ensuring minimal standby power loss. Its 10/1000 µs clamping performance is validated across temperature, with derating curves confirming stable 4600 W capability up to TC = +125 °C before linear reduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 16 V - Maximum continuous reverse operating voltage before significant leakage; sets minimum system bus margin for 12 V nominal automotive rails. |
| VBR (min/max) | 17.8–19.7 V @ 5 mA - Ensures reliable turn-on above normal transients while avoiding false triggering during battery ripple or cranking dips. |
| VC @ IPP | 26.0 V @ 177 A (10/1000 µs) - Limits downstream voltage stress to safe levels for 30 V-rated CAN transceivers and microcontrollers. |
| PPK | 4600 W - Sustains single-pulse load-dump energy (up to 10 ms exponential) without failure, per ISO16750-2 requirements. |
| RθJC | 1.0 °C/W - Enables direct PCB copper pour heatsinking; allows >5 W steady-state dissipation at TC = +25 °C with minimal temperature rise. |
| IFSM | 600 A @ 8.3 ms - Withstands high-current alternator surge events without bond-wire fusing or junction degradation. |
| TJ Range | –55 °C to +175 °C - Fully specified for under-hood ECU environments, including engine control modules and transmission controllers. |
Pinout & Package
DO-218 (Type E) molded plastic package with heatsink-integrated anode terminal; cathode marked by bar on top surface. Anode connects directly to heatsink tab for optimal thermal path and low-inductance surge conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (+) | Surge current entry point and thermal interface | Connected to PCB copper pour or chassis ground; serves as primary heat sink and low-impedance return path for transient energy. |
| Cathode (–) | Protected circuit connection node | Links to sensitive IC power rail (e.g., MCU VDD); clamps voltage to ≤26.0 V when transient exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| 4600 W peak pulse power | Meets ISO16750-2 Pulse 5a (load dump) without external heatsink, enabling compact placement near protected ICs. |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage stress on downstream 24 V tolerant components, reducing need for secondary protection stages. |
| AEC-Q101 qualification | Validated for automotive use with HTOL, temperature cycling, and ESD testing-supports PPAP documentation for Tier 1 suppliers. |
| Lead-free, halogen-free, RoHS 3 compliant | Enables compliance with EU automotive recycling directives and eliminates brominated flame retardants in high-reliability assemblies. |
| 1.0 °C/W thermal resistance | Permits >5× higher steady-state power handling than SMA packages, supporting dual-role use in both surge suppression and thermal monitoring paths. |
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 unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-Q | Lower PPK (400 W), SMA package, RθJC = 35 °C/W, VRWM = 16 V, VC = 26.0 V @ 15.3 A | Not suitable for load-dump; limited to ISO7637-2 Pulse 1/2a only; requires external heatsink for >1 W continuous dissipation | Select when space-constrained and surge energy is below 100 mJ; avoid for alternator-related transients. |
| TPSMD16A | Same DO-218 package, PPK = 3000 W, VRWM = 16 V, VC = 26.5 V @ 113 A, RθJC = 1.2 °C/W | Lower peak power margin reduces safety factor for worst-case ISO16750-2 Pulse 5a; not AEC-Q101 qualified | Acceptable for non-safety-critical cabin modules where full load-dump immunity is not mandated. |
Compared with SMAJ16A-Q and TPSMD16A, DM6W16AQ-13 delivers 15% higher clamping efficiency, 54% greater peak power headroom, and certified automotive qualification-making it the only choice for front-end protection in engine bay and EPS applications requiring full ISO16750-2 compliance.

FAQ
What is the maximum clamping voltage of DM6W16AQ-13 under standard test conditions?
The maximum clamping voltage (VC) is 26.0 V when subjected to a 10/1000 µs waveform with a peak pulse current (IPP) of 177 A. This value is guaranteed across the full operating temperature range (–55 °C to +175 °C) and reflects worst-case device behavior under standardized surge testing per IEC 61000-4-5 methodology.
Is DM6W16AQ-13 compatible with lead-free reflow soldering processes?
Yes. The device uses matte tin-plated terminals and is rated for soldering per MIL-STD-202, Method 208. Its DO-218 package supports peak reflow temperatures up to 260 °C for 30 seconds, and it complies with J-STD-020 moisture sensitivity level 1-requiring no baking prior to assembly.
How does the heatsink-as-anode configuration affect PCB layout?
The anode is electrically and thermally tied to the exposed metal tab, which must be connected to a large copper pour or chassis ground plane. This configuration reduces thermal impedance and inductance but requires isolation of the cathode pad from ground planes to prevent shorting. Layout must follow Diodes' recommended pad dimensions (X = 3.50 mm, Y1 = 9.50 mm) for mechanical reliability.
Can DM6W16AQ-13 be used in bidirectional surge protection circuits?
No. It is a unidirectional TVS diode with anode-heatsink polarity and is not rated for reverse surge conduction. For bidirectional protection (e.g., data lines), a symmetric device such as the DMP1001S or SMAJ16CA-Q must be used instead. Using DM6W16AQ-13 in reverse bias risks permanent breakdown above 16 V.
