Product details
Overview
DM6W17A-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode designed for automotive load dump and ISO 7637-2 surge protection in high-power 12V/24V systems. It delivers 4600W peak pulse power (10/1000µs), clamps at 27.6V max under 167A peak current, and features a 17V reverse standoff voltage with 1.0°C/W junction-to-case thermal resistance in DO-218 package.
For engineers reviewing the DM6W17A-13 datasheet, DM6W17A-13 pinout, DM6W17A-13 application, or DM6W17A-13 equivalent, key selection criteria include ISO16750-2 compliance, low clamping voltage vs. standoff ratio (VC/VRWM ≈ 1.62), high IFSM (600A), thermal stability up to +175°C, and RoHS/halogen-free qualification for automotive-grade reliability.
Technical Context
This unidirectional TVS diode operates as a clamping device across power rails to divert high-energy transients-such as load dump surges (up to 100V, 10ms exponential) and ISO 7637-2 pulses-away from downstream ICs and sensors. Its DO-218 package enables direct heatsink mounting via the anode terminal, leveraging low RθJC (1.0°C/W) for sustained power handling.
The device exhibits tight VBR tolerance (18.9–20.9V at 5mA), low IR (≤10µA @ VRWM), and stable VC performance across temperature (−55°C to +175°C). Its 6W steady-state power rating and derating curve support continuous operation in engine bay environments where case temperatures exceed 125°C.
Key Specifications

IC Role / Device Role / Timing Role: High-energy TVS mounted directly on PCB heatsink adjacent to motor driver ICs. Use Value: 1.0°C/W RθJC allows sustained 6W dissipation during repeated EPS assist cycles, avoiding thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A | Lower PPK (400W), SMA package, RθJC ≈ 50°C/W, no heatsink capability | Suitable only for low-energy pulses (e.g., ESD, data lines); not rated for ISO16750-2 load dump | Select when space-constrained and surge energy <500W; avoid for battery rail protection |
| SMCJ17A | PPK = 1500W, SMC package, RθJC ≈ 10°C/W, limited to 100A IPP | Meets ISO 7637-2 Pulse 1/2a but fails load dump (100V/10ms) due to lower energy capacity | Acceptable for non-load-dump automotive subsystems; insufficient for main battery rail |
Compared with SMAJ17A and SMCJ17A, DM6W17A-13 uniquely supports full ISO16750-2 load dump with 4600W rating and heatsink-integrated thermal management-critical for primary power rail protection where sustained surge energy exceeds 1000W.

FAQ
What is the maximum clamping voltage of DM6W17A-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 27.6V at 167A peak pulse current (IPP) under 10/1000µs waveform conditions. This value is guaranteed across −55°C to +175°C operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Can DM6W17A-13 be used in bidirectional surge protection configurations?
No. DM6W17A-13 is a unidirectional TVS diode with anode-heatsink polarity. Its electrical characteristics-including breakdown voltage and clamping behavior-are specified only for reverse-biased operation. For bidirectional protection, a dedicated symmetric TVS array or two series-opposed unidirectional devices would be required.
How does the DO-218 package enhance thermal performance compared to standard SMC or SMA packages?
The DO-218 (Type E) package integrates a large metal heatsink pad as the anode terminal, enabling direct thermal coupling to PCB copper or external heatsinks. Its RθJC of 1.0°C/W is over 10× lower than SMCJ17A (≈10°C/W) and 50× lower than SMAJ17A (≈50°C/W), allowing sustained power dissipation critical for load dump events.
Is DM6W17A-13 compliant with AEC-Q200 for automotive applications?
Yes. DM6W17A-13 is qualified to AEC-Q200 standards per Diodes Incorporated's product definitions and JEDEC reliability testing protocols. It is rated for operation from −55°C to +175°C and meets humidity, temperature cycling, and mechanical shock requirements defined in the AEC-Q200 stress test schedule.
