Product details
Overview
DM6W16A-13 from Diodes Incorporated is a 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), 26.0 V maximum clamping voltage (VC) at 177 A peak pulse current, 4600 W peak pulse power (10/1000 µs), and DO-218 (Type E) package with anode-heatsink polarity. It is deployed in 12 V automotive power rails to safeguard ECUs against load dump transients.
For engineers reviewing the DM6W16A-13 datasheet, DM6W16A-13 pinout, DM6W16A-13 application, or DM6W16A-13 equivalent, key selection criteria include clamping voltage margin vs. system rail tolerance, thermal resistance (RθJC = 1.0 °C/W), ISO16750-2 compliance, junction temperature range (–55°C to +175°C), and lead-free, halogen-free "Green" qualification per AEC-Q standards.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped crowbar device during transient overvoltage events, conducting surge current from cathode to anode when reverse voltage exceeds breakdown (VBR min = 17.8 V). Its low RθJC (1.0 °C/W) enables effective heat transfer to the heatsink-mounted anode terminal under high-energy 10 ms exponential load dump waveforms.
The device meets ISO 10605 (Pulse A/B), ISO 7637-2 (Pulse 1, 2a, 3a, 3b), and ISO 16750-2 requirements. Its 150 µA max reverse leakage at VRWM and 250 µA max at TJ = +175°C ensures minimal standby power loss in always-on automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 16 V - Maximum continuous reverse operating voltage before significant leakage; sets minimum system rail margin for 12 V nominal systems. |
| VBR (min) | 17.8 V @ 5 mA - Guaranteed breakdown initiation threshold; defines earliest clamping onset under surge conditions. |
| VC @ IPP | 26.0 V @ 177 A (10/1000 µs) - Clamped voltage seen by protected circuit; must remain below IC absolute maximum ratings. |
| PPK | 4600 W (10/1000 µs) - Peak surge energy handling capacity; supports full ISO 16750-2 load dump specification. |
| RθJC | 1.0 °C/W - Thermal resistance from junction to case; enables >5 W steady-state dissipation at TC = +25°C with minimal temperature rise. |
| TJ Range | –55°C to +175°C - Full automotive-grade operating envelope; validated for under-hood ECU placement. |
| IR @ VRWM | 10 µA max @ +25°C - Low leakage preserves battery life in always-on modules such as CAN gateways and body controllers. |
Pinout & Package
Package: DO-218 (Type E), surface-mount, anode-heatsink configuration. Molded plastic body (UL 94V-0), matte tin-plated terminals, polarity indicated by bar (cathode) and circle (anode) markings. Weight: 2.74 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode (Lead) | Surge current input node | Connected to protected line (e.g., battery feed); conducts transient current into anode/heatsink during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| 4600 W peak pulse power | Supports full ISO 16750-2 load dump waveform (10 ms exponential) without failure at TC ≤ +125°C. |
| Low RθJC (1.0 °C/W) | Enables >5× higher steady-state power handling than standard SMA packages; reduces thermal derating in compact layouts. |
| Automotive-qualified reliability | Qualified per AEC-Q standards; suitable for safety-critical ECUs requiring long-term field reliability under thermal cycling. |
| Halogen- and antimony-free "Green" | Meets EU RoHS 3 and automotive chemical content requirements (<900 ppm Br/Cl, <1000 ppm Sb). |
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 transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Lower PPK (400 W), SMA package, RθJC ≈ 45 °C/W, VRWM = 16 V, VC = 26.0 V @ 12.3 A | Not suitable for load dump; limited to ISO 7637-2 Pulse 1/2a only; requires larger board area for thermal relief | Select when cost sensitivity outweighs surge energy requirement and thermal constraints allow. |
| SMCJ16A | PPK = 1500 W, SMC package, RθJC ≈ 12 °C/W, same VRWM/VC, but lower IFSM (100 A) | Acceptable for moderate-duty BCMs but fails ISO 16750-2 load dump testing above +85°C case temperature | Choose for non-load-dump applications where footprint and cost are prioritized over full automotive surge compliance. |
Compared with SMAJ16A and SMCJ16A, DM6W16A-13 delivers 3× higher surge energy capacity and 12× better thermal performance-enabling single-device compliance with ISO 16750-2 in space-constrained under-hood designs without external heatsinking.

FAQ
What is the maximum clamping voltage of DM6W16A-13 under a 10/1000 µs surge?
The maximum clamping voltage (VC) is 26.0 V at 177 A peak pulse current under the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and reflects worst-case device behavior during surge events, ensuring protected circuits remain within safe voltage limits.
Is DM6W16A-13 qualified for automotive applications?
Yes-DM6W16A-13 is built to meet AEC-Q reliability standards and complies with ISO 16750-2 (load dump) and ISO 7637-2 (transient pulses). It is rated for –55°C to +175°C junction temperature and carries Diodes' automotive "Q"-grade qualification documentation, though the non-Q version remains fully compliant for many Tier 2/3 applications.
How should the anode (heatsink) terminal be mounted for optimal thermal performance?
The anode tab must be soldered to a minimum 200 mm² copper pad (2 oz. thickness) or directly to an internal ground plane layer via multiple thermal vias. Per Diodes' layout guidelines, use the recommended DO-218 (Type E) pad dimensions (X = 3.50 mm, Y = 3.00 mm, Y2 = 15.80 mm) to ensure mechanical stability and thermal conduction under repeated surge stress.
Does DM6W16A-13 have polarity marking, and how is it identified?
Yes-polarity is marked on the device body: a bar symbol denotes the cathode lead, and a circle symbol identifies the anode (heatsink) terminal. This matches the DO-218 (Type E) top-view orientation shown in the datasheet, and correct orientation is critical to ensure proper clamping direction and thermal path integrity.
