Product details
Overview
DM6W10A-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode designed for automotive load dump and ISO7637-2 surge protection. It delivers 4600W peak pulse power at 10/1000µs, features a 10V reverse standoff voltage (VRWM), clamps to ≤17.0V at 271A peak current, and operates from –55°C to +175°C in DO-218 package - deployed in engine control units and battery management systems.
For engineers reviewing the DM6W10A-13 datasheet, DM6W10A-13 pinout, DM6W10A-13 application, or DM6W10A-13 equivalent, key selection criteria include verified ISO16750-2 compliance, low thermal resistance (RθJC = 1.0°C/W), high-temperature stability up to +175°C, and automotive-grade qualification per AEC-Q standards.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to clamp transient overvoltages in automotive power rails. Its unidirectional polarity and heatsink-anode configuration enable efficient heat dissipation during 8.3ms load dump events, with guaranteed clamping performance across –55°C to +175°C junction temperature range.
The device meets ISO 10605 (Pulse A/B), ISO 7637-2 (Pulse 1, 2a, 3a, 3b), and ISO 16750-2 load dump requirements. Its 1.0°C/W junction-to-case thermal resistance and 6W steady-state power rating support reliable operation under sustained thermal stress in under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 4600W @ 10/1000µs - sustains automotive load dump surges without failure |
| Reverse Standoff Voltage | 10V - blocks normal 12V system voltage while remaining inactive until surge onset |
| Clamping Voltage | ≤17.0V @ 271A - limits downstream IC voltage to safe level during transients |
| Junction-to-Case Thermal Resistance | 1.0°C/W - enables direct heatsink mounting for thermal management in high-power surges |
| Operating Temperature Range | –55°C to +175°C - qualified for under-hood automotive applications including ECU and BCM |
| Surge Current Rating | 600A IFSM @ 8.3ms half-sine - withstands repetitive load dump events per ISO16750-2 |
| Leakage Current | ≤15µA @ VRWM - minimizes standby power loss in always-on vehicle subsystems |
Pinout & Package
Package: DO-218 (Type E), surface-mount, molded plastic UL 94V-0 housing; heatsink tab serves as anode terminal; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Positive surge return path | Primary thermal interface - must be soldered to copper pour or heatsink for RθJC = 1.0°C/W |
| Cathode (Top Marked Pin) | Transient clamping node | Connected to protected line (e.g., battery rail); conducts avalanche current during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| ISO16750-2 Load Dump Compliance | Validated for 12V system load dump surges up to 35V for 400ms - protects against alternator disconnection events |
| Low Thermal Resistance | RθJC = 1.0°C/W enables >90% of surge energy to dissipate through heatsink, not PCB traces |
| AEC-Q Qualified Reliability | Qualified per JEDEC standards referenced in AEC-Q - supports automotive production without additional qualification |
| Halogen & Antimony Free | <900ppm Br, <900ppm Cl, <1000ppm Sb - meets automotive green material requirements (JIS C0950) |
| RoHS 3 Compliant | Fully compliant with EU Directive 2015/863/EU - suitable for global automotive supply chain deployment |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower peak power (400W), DO-214AC package, RθJC ≈ 50°C/W | Not qualified for ISO16750-2 load dump; limited to infotainment or low-energy modules | Select only for non-automotive 12V systems with <50A surge exposure |
| SMCJ10A | Higher peak power (1500W), DO-214AB package, RθJC ≈ 10°C/W | Lacks AEC-Q qualification and ISO16750-2 validation; unsuitable for safety-critical ECU use | Acceptable for industrial 12V controls where automotive certification is not required |
Compared with SMAJ10A and SMCJ10A, DM6W10A-13 uniquely combines 4600W surge capacity, 1.0°C/W thermal resistance, and full AEC-Q/ISO16750-2 compliance - enabling single-device protection in high-reliability automotive power domains where thermal margin and standard conformance are non-negotiable.

FAQ
What is the maximum clamping voltage of DM6W10A-13 at rated peak current?
The DM6W10A-13 clamps to a maximum of 17.0V at 271A peak pulse current (10/1000µs waveform), as specified in the Electrical Characteristics table. This value is measured at TA = +25°C and remains stable across its full operating temperature range due to low thermal coefficient design.
Is DM6W10A-13 qualified for automotive use per AEC-Q200?
DM6W10A-13 is qualified to JEDEC standards referenced in AEC-Q200 for high-reliability automotive applications. While it is not explicitly labeled "AEC-Q200 certified" in marketing materials, Diodes confirms qualification per applicable stress tests (including temperature cycling, humidity bias, and surge endurance) as defined in the AEC-Q200 standard.
Can DM6W10A-13 be used in 24V commercial vehicle systems?
DM6W10A-13 is rated for 10V VRWM and optimized for 12V automotive systems. For 24V applications, Diodes offers DM6W24A-13 (24V VRWM, 38.9V clamping), which shares identical DO-218 packaging, thermal performance, and qualification - making it the appropriate variant for commercial vehicle battery rails.
What is the recommended PCB layout for optimal thermal performance?
For optimal thermal performance, the anode (heatsink tab) must be soldered to ≥250 mm² of 2oz copper connected to internal ground or thermal plane. Pad dimensions should follow Diodes' DO-218 Type E layout: 3.3mm (G) × 11.0mm (X1) with 3.0mm (Y) spacing. Avoid thermal relief on the anode pad to maintain RθJC ≤ 1.0°C/W.
