Product details
Overview
DM6W22AQ-13 from Diodes Incorporated is a 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 4600W peak pulse power (10/1000µs), 22V reverse standoff voltage (VRWM), 35.5V max clamping voltage at 130A IPP, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the DM6W22AQ-13 datasheet, DM6W22AQ-13 pinout, DM6W22AQ-13 application, or DM6W22AQ-13 equivalent, key selection criteria include clamping performance under ISO16750-2 Pulse 5a, thermal resistance (RθJC = 1.0°C/W), anode-heatsink polarity, and compliance with automotive change control and PPAP requirements.
Technical Context
This unidirectional TVS diode operates with heatsink-as-anode polarity and delivers robust transient suppression using silicon avalanche technology. Its 1.0°C/W junction-to-case thermal resistance enables high-power dissipation at elevated case temperatures, supporting sustained operation up to +175°C junction temperature.
The device meets ISO 16750-2 Pulse 5a (load dump) and ISO 7637-2 Pulse 1, 2a, 3a, and 3b waveforms. With 10µA max reverse leakage at VRWM and only 150µA at +175°C, it maintains low standby power loss in battery-sensitive automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 4600W (10/1000µs waveform; sustains automotive load-dump surges without failure) |
| Reverse Standoff Voltage | 22V (stable blocking up to battery system nominal voltage + margin) |
| Clamping Voltage | 35.5V @ 130A IPP (limits downstream IC stress during 80V+ transients) |
| Junction-to-Case Thermal Resistance | 1.0°C/W (enables direct heatsink mounting for reliable 6W steady-state dissipation) |
| Operating Temperature Range | −55°C to +175°C (validated for engine compartment and transmission control environments) |
| AEC-Q101 Qualified | Yes (qualified per stress test standard for automotive discrete semiconductors) |
Pinout & Package
Package: DO-218 (Type E), surface-mount molded plastic housing with heatsink-integrated anode terminal. Polarity marked by bar symbol denoting cathode; heatsink tab is electrically connected to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Positive surge current path and thermal interface | Must be soldered to PCB copper pour ≥ 200 mm² for RθJC = 1.0°C/W performance |
| Cathode (Top Surface Pad) | Surge return path and voltage reference node | Connected to protected line (e.g., 12V rail); clamps to anode when transient exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| 4600W Peak Pulse Power | Handles full ISO16750-2 Pulse 5a (87V, 400ms) without degradation when mounted to heatsink |
| Low Clamping Ratio (VC/VRWM = 1.61) | Minimizes overvoltage stress on downstream CAN transceivers and microcontrollers |
| 1.0°C/W Thermal Resistance | Enables 6W continuous power dissipation at TC = +25°C without forced cooling |
| AEC-Q101 Qualification | Validated for automotive use with PPAP documentation support and IATF 16949 manufacturing |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) 12V Rail |
|---|---|
Use Scenario: Protects ECU main 12V supply against alternator load-dump events (ISO16750-2 Pulse 5a) and battery reversal transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed upstream of DC-DC converter input. Use Value: Limits transient voltage to ≤35.5V, preventing damage to 40V-rated input MOSFETs and LDOs. |
Use Scenario: Shields BCM power domain from ISO7637-2 Pulse 1 (inductive switch-off) and Pulse 3b (capacitive coupling). IC Role / Device Role / Timing Role: Primary surge suppression device on fused 12V distribution bus. Use Value: Absorbs 130A peak current while maintaining <10µA leakage at 22V, minimizing sleep-current impact. |
| Advanced Driver Assistance Systems (ADAS) Camera Module | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Safeguards image sensor and SerDes power rails in automotive camera modules exposed to harness-induced surges. IC Role / Device Role / Timing Role: Secondary protection stage after fuse and primary TVS, placed near connector entry. Use Value: 35.5V clamping ensures compatibility with 3.3V/5V analog front-end ICs operating behind DC-DC regulation. |
Use Scenario: Protects H-bridge gate drivers and current-sense amplifiers from motor back-EMF and battery transients. IC Role / Device Role / Timing Role: High-energy TVS mounted directly to metal chassis heatsink adjacent to motor driver IC. Use Value: 1.0°C/W RθJC allows direct thermal coupling to EPS housing, sustaining repeated 4600W pulses without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Lower PPK (400W), SMA package, RθJC ≈ 50°C/W, no AEC-Q101 qualification | Limited to non-automotive or low-energy industrial I/O protection | Select only for cost-sensitive non-automotive designs where 4600W surge immunity is not required |
| SMCJ22A | PPK = 1500W, SMC package, RθJC ≈ 3.5°C/W, AEC-Q101 qualified but lower energy rating | Suitable for moderate-load-dump zones (e.g., infotainment), not under-hood ECUs | Choose when footprint constraints prevent DO-218 use and 1500W peak power suffices |
Compared with SMAJ22A and SMCJ22A, DM6W22AQ-13 delivers 3× higher surge energy handling and 35× lower thermal resistance-critical for sustained load-dump survival in engine bay locations where ambient temperatures exceed +125°C.

FAQ
What is the maximum clamping voltage of DM6W22AQ-13 at rated peak pulse current?
The maximum clamping voltage VC is 35.5V at 130A peak pulse current (IPP) under 10/1000µs waveform 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.
How is polarity identified on the DM6W22AQ-13 DO-218 package?
Polarity is marked with a bar symbol on the top surface indicating the cathode terminal; the metal heatsink tab is the anode and must be connected to the positive side of the protected circuit. This anode-heatsink configuration enables direct thermal coupling to PCB copper or external heatsinks.
Does DM6W22AQ-13 meet automotive qualification standards beyond AEC-Q101?
Yes-DM6W22AQ-13 is PPAP-capable and manufactured in IATF 16949-certified facilities. It complies with ISO 16750-2 (Pulse 5a load dump) and ISO 7637-2 (Pulse 1, 2a, 3a, 3b), and carries RoHS 3 and halogen-free "Green" certification per Diodes' definitions.
What is the recommended PCB layout for optimal thermal performance?
Mount the anode (heatsink tab) to a minimum 200 mm² copper pour connected via ≥4 thermal vias (0.3mm diameter) to inner-layer ground planes. Use the suggested pad dimensions from Diodes' DO-218 outline: X = 3.50 mm, Y = 3.00 mm, Y1 = 9.50 mm, Y2 = 15.80 mm, ensuring full tab coverage.
