Product details
Overview
DM6W14AQ-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 14V reverse standoff voltage (VRWM), 15.6–17.2V breakdown voltage (VBR), 23.2V clamping voltage (VC) at 198A peak pulse current, and operates from –55°C to +175°C.
For engineers reviewing the DM6W14AQ-13 datasheet, DM6W14AQ-13 pinout, DM6W14AQ-13 application, or DM6W14AQ-13 equivalent, this part supports high-reliability automotive power rail protection where low thermal resistance (1.0°C/W), high-temperature stability, and ISO16750-2 compliance are critical selection criteria.
Technical Context
This unidirectional TVS diode uses an avalanche junction structure optimized for fast response (<1 ns) to transient overvoltages on 12V/24V automotive systems. Its DO-218 package integrates a heatsink-anode configuration with low RθJC (1.0°C/W) to sustain 4600W peak pulse power (10/1000µs) without thermal runaway.
The device meets AEC-Q200 stress test requirements and delivers <10µA reverse leakage at VRWM up to +175°C. Clamping performance is validated across ISO7637-2 Pulse 1, 2a, 3a, 3b and ISO16750-2 load dump waveforms, with typical capacitance of ~30pF at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 4600W (10/1000µs waveform) - sustains full load dump surges without failure |
| Reverse Standoff Voltage | 14V - sets minimum operating margin above nominal 12V battery rail |
| Clamping Voltage | 23.2V @ 198A - limits downstream IC voltage stress during surge events |
| Thermal Resistance | 1.0°C/W (Junction-to-Case) - enables direct heatsink mounting for thermal management |
| Operating Temperature | –55°C to +175°C - qualified for under-hood automotive environments |

| Leakage Current | ≤10µA @ VRWM, +175°C - ensures minimal standby power loss in hot-cranking conditions |
Pinout & Package
Package: DO-218 (Type E), surface-mount, molded plastic (UL 94V-0), heatsink-anode polarity (bar = cathode, circle = anode). Weight: 2.74g.
| 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 |
|---|---|---|---|
| SMAJ14A-Q | Lower PPK (400W), SMA package, RθJC = 35°C/W | Not suitable for load dump; limited to ISO7637-2 Pulse 1/3 only | Select only for cost-sensitive non-load-dump circuits with adequate board-level heatsinking |
| SMCJ14A-Q | PPK = 1500W, SMC package, RθJC = 10°C/W, same VRWM | Meets ISO16750-2 but fails 4600W load dump requirement | Use where space constraints prevent DO-218 mounting but higher surge rating than SMAJ is needed |
Compared with SMAJ14A-Q and SMCJ14A-Q, DM6W14AQ-13 uniquely delivers 4600W load dump capability in a thermally optimized DO-218 package-enabling single-device compliance with OEM-level surge standards without external heatsinks or parallel devices.

FAQ
What is the maximum clamping voltage of DM6W14AQ-13 at rated peak pulse current?
The clamping voltage VC is 23.2V at IPP = 198A (10/1000µs waveform), measured per JEDEC standard test conditions. This value is guaranteed across the full operating temperature range (–55°C to +175°C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Can DM6W14AQ-13 replace DM6W14A in existing designs?
Yes-DM6W14AQ-13 is the automotive-qualified version of DM6W14A, sharing identical electrical specs, package (DO-218), and pinout. The "Q" suffix indicates AEC-Q200 qualification, including extended temperature validation, enhanced process controls, and lot-level traceability required for automotive production.
How should the anode heatsink tab be mounted for optimal thermal performance?
The anode tab must be soldered to a minimum 200 mm² copper area (2 oz. thickness) or directly to a metal chassis using thermally conductive adhesive or screw mounting. Achieving RθJC = 1.0°C/W requires full tab contact-partial soldering or air gaps degrade thermal performance and risk thermal runaway during repeated surges.
Does DM6W14AQ-13 meet RoHS 3 and halogen-free requirements?
Yes-this device complies with EU Directive 2015/863/EU (RoHS 3), contains <900ppm bromine and chlorine (total <1500ppm), and <1000ppm antimony compounds. It carries Diodes' "Green" designation and uses matte tin lead-free plating per MIL-STD-202, Method 208.
