Product details
Overview
DM6W14A-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 delivers 4600W peak pulse power (10/1000µs), clamps at 23.2V under 198A peak current, and features a 14V reverse standoff voltage with low thermal resistance (1.0°C/W) for high-reliability engine control and body electronics.
For engineers reviewing the DM6W14A-13 datasheet, DM6W14A-13 pinout, DM6W14A-13 application, or DM6W14A-13 equivalent, key selection criteria include clamping voltage vs. system rail tolerance, IFSM rating for surge margin, thermal derating above +25°C, and DO-218 package compatibility with high-power PCB layouts.
Technical Context
This unidirectional TVS diode operates with anode-connected heatsink polarity and is optimized for fast response to load dump transients (ISO16750-2) and repetitive surges (ISO7637-2 Pulse 1/2a/3a/3b). Its 1.0°C/W junction-to-case thermal resistance enables sustained power dissipation up to 6W at TC = +25°C, with derating to zero at +175°C case temperature.
Electrical behavior is defined by a 15.6–17.2V breakdown range at 5mA test current, <10µA reverse leakage at 14V VRWM, and 23.2V clamping voltage at 198A IPP. It meets AEC-Q200 stress testing requirements and is qualified for automotive-grade reliability per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 4600W (10/1000µs waveform; sustains single-event load dump surges without failure) |
| Clamping Voltage | 23.2V @ 198A IPP (limits downstream IC voltage during worst-case surge, protecting 24V-rated components) |
| Reverse Standoff | 14V (matches nominal 12V automotive battery systems with margin for ripple and cold-crank dips) |
| Breakdown Voltage | 15.6–17.2V @ 5mA (ensures reliable turn-on before system overvoltage damages sensitive nodes) |
| Thermal Resistance | 1.0°C/W (junction-to-case; enables efficient heat transfer to heatsink or copper pour for continuous operation) |
| Surge Current | 600A IFSM (8.3ms half-sine; withstands repeated cranking-induced surges without degradation) |
| Operating Temp | −55°C to +175°C (supports under-hood placement in engine control units and transmission modules) |
Pinout & Package
Package: DO-218 (Type E) molded plastic case with matte tin-plated terminals; heatsink tab is anode (polarity indicator marked by bar symbol); weight ≈2.74g; UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Current entry point during clamping | Must be soldered to large copper area or heatsink for thermal management and low-inductance path |
| Cathode (Top Lead) | Current exit point during clamping | Connected to protected line (e.g., battery feed); polarity critical-reverse connection disables protection |
Key Features
| Feature | Design Value |
|---|---|
| 4600W Peak Pulse Power | Handles full ISO16750-2 load dump energy (up to 120V, 400ms) without failure when properly heatsinked |
| Low Clamping Ratio | VC/VRWM = 1.66 (23.2V / 14V) ensures tight voltage limiting relative to system rail, reducing stress on downstream regulators |
| AEC-Q200 Qualified | Validated for automotive use via temperature cycling, humidity bias, mechanical shock, and vibration tests per JEDEC standards |
| Lead-Free & Halogen-Free | RoHS 3 compliant (<900ppm Br/Cl, <1000ppm Sb); compatible with lead-free reflow and green manufacturing requirements |
| DO-218 Thermal Performance | 1.0°C/W RθJC enables >5W steady-state dissipation at TC ≤ +75°C-critical for under-hood ECU designs |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Protects microcontroller power rails and CAN transceivers from alternator load dump spikes during battery disconnect events. IC Role / Device Role: Unidirectional TVS placed between battery input and DC-DC converter input stage.

| Transmission Control Module (TCM) | Advanced Driver Assistance Systems (ADAS) Power Supply |
Use Scenario: Safeguards solenoid driver ICs and position sensor interfaces against cranking-induced voltage reversals and inductive kickback. IC Role / Device Role: High-energy TVS mounted directly on power entry connector with direct heatsink coupling. Use Value: 600A IFSM rating withstands repeated 8.3ms surges during gear-shift actuation, preserving solenoid timing accuracy. |
Use Scenario: Secures 5V/3.3V power domains feeding radar SoCs and camera ISPs against conducted transients from adjacent high-power actuators. IC Role / Device Role: Secondary-level clamping after front-end filter, placed near point-of-load regulators. Use Value: Low 1.0°C/W thermal resistance allows integration into compact ADAS domain controllers without external heatsinks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A | Lower PPK (400W), DO-214AC package, RθJC ≈ 40°C/W | Suitable only for low-energy surges (ISO7637-2 Pulse 1/3); not rated for load dump | Select when cost-sensitive non-automotive industrial designs require basic ESD/surge protection with minimal board space. |
| SMCJ14A | PPK = 1500W, DO-214AB package, RθJC ≈ 10°C/W, same VRWM | Meets ISO7637-2 but lacks ISO16750-2 load dump qualification; limited thermal headroom | Choose for mid-tier automotive modules where 1500W clamping suffices and DO-218 footprint is unavailable. |
Compared with SMAJ14A and SMCJ14A, DM6W14A-13 provides 3× higher surge energy handling and 10× better thermal performance-enabling robust protection in high-temperature, high-reliability under-hood applications where sustained clamping stability is mandatory.

FAQ
What is the maximum operating temperature for DM6W14A-13?
The DM6W14A-13 supports junction temperatures from −55°C to +175°C, with case temperature derating starting at +25°C. At TC = +100°C, its steady-state power dissipation drops to ~3.5W based on the published derating curve (Figure 1), making it suitable for under-hood ECU mounting without active cooling.
Is DM6W14A-13 pin-compatible with other DO-218 TVS diodes?
Yes-DM6W14A-13 uses the standard DO-218 (Type E) outline with anode-heatsink/cathode-lead polarity. Its pad layout matches Diodes' DO-218 package drawings (D2 = 10.0mm, E = 8.5mm, H = 15.5mm), enabling drop-in replacement with other DO-218 TVS devices like SMBJ14A or SMCJ14A, provided thermal and electrical specs align.
Does DM6W14A-13 meet AEC-Q200 requirements?
Yes-DM6W14A-13 is explicitly qualified to AEC-Q200 Rev D stress test standards per Diodes' product definitions page. This includes passing temperature cycling, humidity bias, mechanical shock, and vibration tests required for automotive passive components, with full qualification data available upon request.
How does the clamping voltage change with temperature?
Clamping voltage increases with junction temperature at a typical coefficient of +0.08%/°C. At TJ = +125°C, VC rises to approximately 24.5V (vs. 23.2V at +25°C), remaining within safe margins for 28V-rated downstream ICs. This positive tempco is inherent to silicon avalanche structure and documented in Diodes' thermal characterization data.
