Product details
Overview
DM6W17AQ-13 from Diodes Incorporated is a 4600W 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 17V reverse standoff voltage (VRWM), 27.6V max clamping voltage (VC) at 167A peak pulse current, and 1.0°C/W junction-to-case thermal resistance - enabling robust overvoltage protection in 12V/24V vehicle power systems.
For engineers reviewing the DM6W17AQ-13 datasheet, DM6W17AQ-13 pinout, DM6W17AQ-13 application, or DM6W17AQ-13 equivalent, this part delivers verified ISO16750-2 compliance, high-temperature stability up to +175°C, low leakage (<10 µA at VRWM), and AEC-Q-qualified reliability for engine control units, body electronics, and ADAS power rails.
Technical Context
This unidirectional TVS diode operates as a clamping device with anode-connected heatsink configuration, triggered by reverse-biased avalanche breakdown above its 17V standoff threshold. Its 10/1000µs waveform rating of 4600W and 600A IFSM capability support single-pulse and repetitive surge suppression in automotive battery line transients.
The DO-218 package provides low thermal resistance (RθJC = 1.0°C/W) and high power density, allowing direct mounting to PCB copper pour for effective heat dissipation during 10ms exponential load dump events. Its 2.74g mass and UL 94V-0 molded plastic housing meet mechanical durability requirements for under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 4600W @ 10/1000µs - sustains full-rated surge energy without failure in ISO7637-2 Pulse 5a load dump events |
| Reverse Standoff Voltage | 17V - blocks normal 12V/24V system voltages while remaining inactive until surge exceeds threshold |
| Clamping Voltage | 27.6V @ 167A - limits downstream IC voltage to safe level during worst-case transient, protecting 30V-rated components |
| Junction-to-Case Thermal Resistance | 1.0°C/W - enables efficient heat transfer to heatsink or copper plane, supporting continuous operation at TC ≤ +125°C |
| Operating Temperature Range | −55°C to +175°C - qualified for under-hood placement in engine control modules and transmission ECUs |
| Leakage Current | <10 µA @ 17V, +175°C - ensures minimal standby power loss and signal integrity in always-on vehicle networks |
| Surge Current Rating | 600A @ 8.3ms half-sine - withstands high-energy battery disconnection surges per ISO16750-2 Annex A |
Pinout & Package
Package: DO-218 (Type E), surface-mount, molded plastic with UL 94V-0 flammability rating; heatsink tab is anode (pin 1), cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A-Q | Lower PPK (400W), SMA package, RθJC ≈ 50°C/W | Limited to low-energy ISO7637-2 Pulse 1/2a; unsuitable for load dump | Select only for cost-sensitive non-load-dump circuits where 17V clamping is required but surge energy is <500W |
| SMCJ17A-Q | Same 17V VRWM, 400W PPK, SMC package, RθJC ≈ 10°C/W | Cannot sustain ISO16750-2 load dump; derates to ~200W at +125°C case temp | Use when board space permits larger SMC footprint and application does not require 4600W rating |
Compared with SMAJ17A-Q and SMCJ17A-Q, DM6W17AQ-13 uniquely delivers 4600W surge capacity in a compact DO-218 package with 1.0°C/W thermal resistance - making it the only option among the three qualified for full automotive load dump protection without external heatsinking.

FAQ
What is the maximum clamping voltage of DM6W17AQ-13 at rated peak pulse current?
The maximum clamping voltage (VC) is 27.6V at 167A peak pulse current under 10/1000µs waveform conditions, measured per DS40427 Rev. 6–2. This value is guaranteed across −55°C to +175°C operating junction temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Is DM6W17AQ-13 suitable for bidirectional surge protection?
No - DM6W17AQ-13 is a unidirectional TVS diode with anode-connected heatsink and cathode-marked terminal. It conducts only during reverse-biased overvoltage events. For bidirectional protection (e.g., data lines), separate symmetric devices like P6SMB series or dedicated bidirectional TVS arrays must be used.
How does the DO-218 package improve thermal performance compared to SMA or SMC packages?
The DO-218 (Type E) package achieves 1.0°C/W junction-to-case thermal resistance due to its integrated metal heatsink tab, which provides direct thermal conduction path to PCB copper. In contrast, SMA packages exhibit ~50°C/W and SMC packages ~10°C/W, limiting their sustainable surge energy without external heatsinks.
Does DM6W17AQ-13 require derating at elevated ambient temperatures?
Yes - power derating follows Fig. 1 in DS40427: PM(AV) drops linearly from 6.0W at TC = +25°C to 0W at TC = +125°C. At +100°C case temperature, maximum average power is 1.2W. Surge ratings remain valid only if terminals are maintained at ambient temperature per Note 6.
