Product details
Overview
DM5W17AQ-13 from Diodes Incorporated is a 3600W 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 a 17V reverse standoff voltage (VRWM), 18.9–20.9V breakdown voltage (VBR), and clamps to ≤27.6V at 130A peak pulse current (10/1000µs), enabling robust protection of 12V automotive power rails.
For engineers reviewing the DM5W17AQ-13 datasheet, DM5W17AQ-13 pinout, DM5W17AQ-13 application, or DM5W17AQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, 1.1°C/W thermal resistance (RθJC), ISO16750-2 Pulse A/B compliance, and heatsink-as-anode polarity configuration for high-power dissipation in engine control units and body electronics.
Technical Context
This TVS diode operates as a unidirectional clamping device with anode-connected heatsink, optimized for fast response to high-energy transients. Its low clamping ratio (VC/VBR ≈ 1.42) and <10µA reverse leakage at VRWM ensure minimal standby power loss and stable DC bias integrity under harsh automotive conditions.
The device leverages silicon avalanche technology with controlled junction geometry to sustain 3600W non-repetitive peak pulse power (10/1000µs) while maintaining thermal stability up to +175°C junction temperature. Its DO-218 package provides low thermal resistance and mechanical robustness for under-hood mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 17 V - Maximum continuous reverse operating voltage before clamping begins; matches nominal 12V automotive system with safety margin. |
| VBR @ IT=5mA | 18.9–20.9 V - Breakdown voltage range ensures reliable turn-on during surges without premature conduction. |
| VC @ IPP=130A | ≤27.6 V - Clamping voltage limits downstream IC stress during ISO16750-2 load dump events. |
| PPK (10/1000µs) | 3600 W - Peak pulse power rating defines maximum transient energy absorption capability per event. |
| RθJC | 1.1 °C/W - Low junction-to-case thermal resistance enables efficient heat transfer to PCB copper or heatsink. |
| TJ Range | −55 to +175 °C - Full automotive temperature range support for under-hood ECU and power module applications. |
Pinout & Package
Package: DO-218 (Type E), molded plastic with UL 94V-0 flammability rating; heatsink tab serves as anode terminal; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Heatsink Tab | Anode (+) | Primary current path and thermal interface; must be connected to high-current ground plane or heatsink for optimal power handling. |
| Lead 1 (Bar-marked side) | Cathode (−) | Signal-side connection point; polarity indicator ensures correct orientation during PCB layout and assembly. |
Key Features

| Low RθJC = 1.1°C/W | Enables >80% of rated 3600W pulse power to be safely dissipated without derating at TC = +25°C. |
| RoHS 3 & Halogen-free | Complies with EU Directive 2015/863/EU and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb)-supports global vehicle emissions certifications. |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Protection |
|---|---|
Use Scenario: Protects 12V supply rail of gasoline/diesel engine ECUs against alternator load dump spikes up to 35V. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed upstream of DC/DC converters and microcontrollers. Use Value: Limits transient overvoltage to ≤27.6V, preventing latch-up or gate oxide damage in 3.3V/5V logic and analog front-ends. | Use Scenario: Shields CAN transceiver power pins from coupled surges induced by nearby high-current switching (e.g., window lift motors). IC Role / Device Role / Timing Role: Secondary-level surge suppression between main fuse and CAN bus regulator. Use Value: Maintains <10µA leakage at 17V VRWM to avoid disrupting low-quiescent-current sleep modes in BCM standby operation. |
| ADAS Camera Power Supply | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Guards image sensor and ISP power inputs in rear-view or surround-view cameras exposed to battery transients during cold-cranking. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 5V or 3.3V camera rail, placed after LDO but before sensor IC. Use Value: Achieves <100ns response time and clamps 130A pulses without degradation-preserves signal integrity during critical video capture windows. | Use Scenario: Protects H-bridge gate driver ICs and current sense amplifiers from inductive kickback during EPS motor commutation. IC Role / Device Role / Timing Role: High-energy TVS on 12V auxiliary rail feeding motor control logic and gate drivers. Use Value: Withstands 500A IFSM (8.3ms half-sine) and 3600W PPK-prevents catastrophic failure during emergency steering assist maneuvers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A | Lower PPK (400W), SMA package, RθJC ≈ 50°C/W, no AEC-Q101 qualification | Not suitable for load dump; limited to low-energy ISO7637-2 Pulse 3a/b only | Select when cost sensitivity outweighs automotive qualification and high-energy surge needs. |
| SMCJ17A | PPK = 1500W, SMC package, RθJC ≈ 2.5°C/W, AEC-Q101 optional (not standard) | Supports moderate load dump but fails ISO16750-2 Pulse A without derating; lower thermal margin | Choose if board space allows larger SMC footprint and full 3600W rating is not required. |
Compared with SMAJ17A and SMCJ17A, DM5W17AQ-13 delivers 2.4× higher peak power and 2.3× lower thermal resistance in a compact DO-218 package, making it the only option qualified for full ISO16750-2 Pulse A compliance in space-constrained automotive modules.

FAQ
What is the maximum clamping voltage of DM5W17AQ-13 at rated peak current?
The maximum clamping voltage (VC) is 27.6 V at 130 A peak pulse current (10/1000 µs waveform), measured per JEDEC standards. This value is guaranteed across the full operating temperature range (−55°C to +175°C) and ensures downstream components remain within safe voltage limits during ISO16750-2 load dump events.
Is DM5W17AQ-13 suitable for bidirectional surge protection?
No, DM5W17AQ-13 is a unidirectional TVS diode with anode-connected heatsink and cathode-marked lead. It conducts only during positive transients on the cathode relative to anode. For bidirectional protection, two devices in series-opposing configuration or a dedicated bidirectional TVS (e.g., DM5W17CAQ-13) must be used.
How does the DO-218 package improve thermal performance over SMA or SMC packages?
The DO-218 (Type E) package uses a large metal heatsink tab directly bonded to the silicon die, achieving RθJC = 1.1°C/W-significantly lower than SMAJ (≈50°C/W) or SMCJ (≈2.5°C/W). This allows sustained 3600W pulse dissipation without thermal runaway, especially critical in sealed under-hood enclosures with limited airflow.
Does DM5W17AQ-13 require derating at elevated ambient temperatures?
Yes-its peak pulse power must be derated above +25°C case temperature per Figure 1 in DS41000 Rev. 7-2. At TC = +100°C, PPK drops to ~2000W (56% of rated value); at TC = +150°C, it falls to ~800W. Proper PCB copper area and heatsinking are essential to maintain TC ≤ +75°C during repetitive surge events.
