Product details
Overview
DM6W15AQ-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode designed for automotive load dump and ISO7637-2 surge protection in 12V/24V systems. It features a 15V reverse standoff voltage (VRWM), 4600W peak pulse power (10/1000µs), 24.4V clamping voltage at 189A peak current, and DO-218 package with anode-heatsink polarity. Used in engine control units and body electronics to safeguard CAN/LIN transceivers and microcontrollers.
For engineers reviewing the DM6W15AQ-13 datasheet, DM6W15AQ-13 pinout, DM6W15AQ-13 application, or DM6W15AQ-13 equivalent, key selection criteria include clamping voltage margin vs. system rail, thermal resistance (RθJC = 1.0°C/W), ISO16750-2 compliance, and automotive-grade AEC-Q qualification - all confirmed in Diodes' DS40427 Rev. 6-2.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device triggered by overvoltage events exceeding its 15V VRWM threshold. Its breakdown voltage (VBR) is specified at 16.7–18.5V (min/max) with 5mA test current, ensuring precise turn-on behavior under transient stress.
The device sustains 600A non-repetitive forward surge current (IFSM, 8.3ms half-sine) and delivers stable clamping up to +175°C junction temperature. Its low thermal resistance (1.0°C/W) enables direct heatsink mounting via the anode terminal, critical for high-energy load dump dissipation in automotive power nets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin above 12V nominal battery rail. |
| VC @ IPP | 24.4 V @ 189 A - Clamped voltage during 10/1000µs surge; ensures downstream ICs see <25V stress under worst-case load dump. |
| PPK | 4600 W - Peak pulse power handling capability; meets ISO16750-2 Load Dump Test Pulse 5a (12V system). |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables efficient heat transfer to PCB copper or external heatsink. |
| TJ Range | −55 to +175 °C - Full automotive temperature range; qualified per AEC-Q standards for under-hood reliability. |
| IFSM | 600 A - Peak forward surge current rating (8.3ms); supports robust protection against alternator-induced surges. |
Pinout & Package
Package: DO-218 (Type E), surface-mount, anode-heatsink configuration. Molded plastic body (UL 94V-0), 2.74g weight, lead-free matte tin plating. Polarity marked with bar (cathode) and circle (anode) on top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink) | Current return path and thermal interface | Must be soldered to large copper pour or heatsink; serves dual electrical/thermal function - critical for 4600W dissipation. |
| Cathode | Transient current sink | Connected to protected line (e.g., battery rail); conducts surge current to ground/anode when VR > VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| ISO16750-2 Load Dump Compliance | Validated for Pulse 5a (12V system, 35V/100ms) - eliminates need for external series impedance in primary protection stage. |
| Low Clamping Ratio (VC/VRWM) | 1.63 - Tight ratio minimizes overvoltage stress on downstream 3.3V/5V logic without requiring additional clamping stages. |
| AEC-Q Qualified Reliability | Qualified to JEDEC standards referenced in AEC-Q - ensures long-term stability in automotive environments with thermal cycling and vibration. |
| Halogen & Antimony Free | <900ppm Br, <900ppm Cl, <1000ppm Sb - meets automotive "Green" material requirements without compromising surge performance. |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) Battery Rail |
|---|---|
Use Scenario: Protects ECU main 12V supply from alternator load dump surges during battery disconnect events. IC Role / Device Role: Primary shunt TVS at input filter stage, clamping transients before DC-DC converters and MCU power rails. Use Value: Withstands 4600W pulses while holding clamped voltage to 24.4V - prevents latch-up or damage to 28V-rated input regulators. |
Use Scenario: Shields BCM microcontroller, CAN transceivers, and LED drivers from ISO7637-2 Pulse 1 (inductive switch-off) and Pulse 3b (capacitive coupling). IC Role / Device Role: Unidirectional TVS placed between battery rail and local ground plane, leveraging DO-218 anode-heatsink for thermal management. Use Value: 1.0°C/W RθJC allows direct PCB copper thermal spreading - avoids discrete heatsinks in space-constrained modules. |
| Infotainment Head Unit Power Supply | ADAS Camera Module Input Protection |
Use Scenario: Guards infotainment system's 12V input against cranking surges and jump-start transients in shared vehicle battery networks. IC Role / Device Role: First-line transient suppressor upstream of EMI filters and buck converters powering SoCs and audio codecs. Use Value: 15V VRWM provides sufficient headroom above 13.5V nominal battery, while 24.4V clamping protects 24V-tolerant PMICs. |
Use Scenario: Secures 12V input of rear-view or surround-view camera modules exposed to harsh under-vehicle electrical noise. IC Role / Device Role: Automotive-grade TVS mounted directly at connector entry point, rated for −40°C to +105°C ambient operation. Use Value: AEC-Q qualification and −55°C to +175°C TJ range ensure reliability across full automotive lifecycle, including hot-soak conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-Q | Lower PPK (400W), SMA package, RθJC = 35°C/W | Not suitable for ISO16750-2 Load Dump; limited to ISO7637-2 Pulse 1/2a/3b only | Select only for cost-sensitive non-load-dump applications where board space is constrained and thermal budget permits higher junction rise. |
| SMCJ15A-Q | Same VRWM (15V), but PPK = 1500W, SMC package, RθJC = 2.5°C/W | Meets ISO7637-2 but fails ISO16750-2 Load Dump due to insufficient peak power | Use where moderate surge energy exists and DO-218 footprint is unavailable; requires larger thermal pad than DM6W15AQ-13. |
Compared with SMAJ15A-Q and SMCJ15A-Q, DM6W15AQ-13 uniquely delivers 4600W peak power in a thermally optimized DO-218 package - enabling single-stage load dump protection without derating or parallel devices, reducing BOM count and layout complexity.

FAQ
What is the difference between DM6W15A and DM6W15AQ-13?
DM6W15AQ-13 is the automotive-qualified version: it carries the 'Q' suffix indicating AEC-Q qualification per JEDEC standards referenced in AEC-Q200, whereas DM6W15A is the commercial-grade variant. Both share identical electrical specs (VRWM = 15V, VC = 24.4V, PPK = 4600W), but only the 'Q' version guarantees extended temperature operation (−55°C to +175°C TJ), enhanced process controls, and full automotive PPAP documentation support.
Can DM6W15AQ-13 be used in 24V systems?
Yes - DM6W15AQ-13 is rated for 15V VRWM and 24.4V clamping, making it suitable for 24V nominal systems where transient suppression must protect components rated up to 28V. Its 4600W peak power and −55°C to +175°C junction range meet ISO16750-2 Pulse 5b (24V system, 58V/100ms), provided proper PCB thermal design supports heat dissipation.
How is the DO-218 anode-heatsink polarity implemented in layout?
The DO-218 package uses the metal heatsink tab as the anode terminal, marked with a circle on the top surface; the cathode is the smaller lead, marked with a bar. Layout requires connecting the heatsink tab to the system ground plane or dedicated thermal pad, while routing the cathode to the protected line - ensuring low-inductance paths and ≥200mm² copper area for optimal thermal performance.
Does DM6W15AQ-13 require external series impedance for ISO16750-2 compliance?
No - DM6W15AQ-13 is designed for direct connection to battery rails and meets ISO16750-2 Load Dump (Pulse 5a) without external series resistance. Its 4600W rating and low clamping voltage (24.4V) allow it to absorb full surge energy while maintaining safe voltage levels for downstream regulators and ICs rated to 28V.
