Product details
Overview
DM5W17A-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode designed for automotive load dump and ISO 7637-2 surge protection. It features a 17 V reverse standoff voltage (VRWM), 27.6 V clamping voltage (VC) at 130 A peak pulse current, and 3600 W peak pulse power dissipation (10/1000 µs). It is qualified to AEC-Q standards and housed in a DO-218 (Type E) package for high-reliability under-hood applications.
For engineers reviewing the DM5W17A-13 datasheet, DM5W17A-13 pinout, DM5W17A-13 application, or DM5W17A-13 equivalent, this device serves as a primary overvoltage clamp in 12 V automotive power rails-particularly where compliance with ISO 16750-2 load dump and ISO 7637-2 Pulse 1/2a/3a/3b is required.
Technical Context
This TVS diode operates as a unidirectional, anode-to-cathode clamping device with polarity indicated by a bar (cathode) and circle (anode) on the DO-218 package. Its low thermal resistance (RθJC = 1.1 °C/W) enables efficient heat transfer to the heatsink-critical during sustained 10 ms exponential load dump events up to 4000 W at +25 °C case temperature.
The device exhibits stable clamping performance across -55 °C to +175 °C operating range, with <10 µA reverse leakage at VRWM and only 150 µA at +175 °C. Its 1.7–2.5 mm heatsink thickness (A3) and 13.5 mm body length (D) are optimized for mechanical robustness and PCB-level thermal management in engine control units and body electronics modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 17 V - Maximum continuous reverse operating voltage before clamping begins; matches nominal 12 V automotive system with margin for battery ripple. |
| VC @ IPP | 27.6 V @ 130 A - Clamped voltage during 10/1000 µs surge; ensures downstream ICs (e.g., MCU power supplies) remain below 30 V absolute max rating. |
| PPK | 3600 W - Peak non-repetitive surge power handling; supports single-event load dump per ISO 16750-2 Class D (≥3500 W). |
| IFSM | 500 A - 8.3 ms half-sine forward surge rating; validates capability to survive alternator-induced surges without bond wire fusing. |
| RθJC | 1.1 °C/W - Junction-to-case thermal resistance; enables direct mounting to metal-core PCB or heatsink for thermal derating control. |
| TJ Range | -55 °C to +175 °C - Full automotive temperature qualification; supports placement near engines or in junction boxes without derating. |
Pinout & Package
Package: DO-218 (Type E), surface-mount, molded plastic (UL 94V-0), anode-heatsink configuration. Polarity marked with cathode bar and anode circle. Weight: 2.74 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink) | Positive terminal / thermal interface | Electrically connected to heatsink pad; must be soldered to large copper area for thermal conduction and low-inductance return path. |
| Cathode (Bar-marked lead) | Clamping output / surge sink | Connected to protected line (e.g., battery rail); conducts surge current to anode/heatsink during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|

| Low RθJC (1.1 °C/W) | Enables >90% of rated power dissipation at TC = +125 °C, reducing need for oversized heatsinks in space-constrained ECUs. |
| AEC-Q qualified | Validated per JEDEC stress test standards for automotive reliability-no additional qualification testing needed for Tier 1 production. |
| Halogen- and antimony-free "Green" | Complies with EU RoHS 3 (2015/863/EU) and automotive OEM material declarations (<900 ppm Br/Cl, <1000 ppm Sb). |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) Battery Rail |
|---|---|
Use Scenario: Protects 12 V input stage of gasoline/diesel engine ECU against alternator load dump surges up to 35 V for 400 ms. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed directly at connector entry point, shunting surge energy to chassis ground via heatsink. Use Value: Limits rail voltage to ≤27.6 V during 130 A transients, preventing damage to 3.3 V/5 V LDOs and CAN transceivers downstream. |
Use Scenario: Shields BCM microcontroller power supply from ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 3b (capacitive discharge) events. IC Role / Device Role / Timing Role: Fast-response clamping diode mounted adjacent to DC-DC converter input, with cathode tied to protected rail and anode to ground plane. Use Value: Achieves <1 ns response time and <10 µA leakage at 17 V, minimizing standby current loss while maintaining EMC immunity. |
| Advanced Driver Assistance System (ADAS) Camera Module | Electric Power Steering (EPS) Motor Controller |
Use Scenario: Safeguards 12 V input of rear-view camera module exposed to battery transients during jump-start or cold-cranking. IC Role / Device Role / Timing Role: Primary overvoltage protector between fuse box and camera's DC-DC stage, leveraging DO-218's mechanical ruggedness for vibration resistance. Use Value: Withstands 500 A 8.3 ms surge without degradation, ensuring uninterrupted video feed during vehicle start-up sequences. |
Use Scenario: Clamps voltage spikes generated by H-bridge motor commutation and regenerative braking in EPS systems. IC Role / Device Role / Timing Role: Bidirectionally referenced TVS (anode grounded, cathode to rail) used in conjunction with reverse-polarity protection MOSFETs. Use Value: Maintains clamping stability at +175 °C ambient-critical for EPS placement near steering column heat sources. |
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 (400 W), SMA package (RθJC ≈ 50 °C/W), 20.9 V VBR min | Not suitable for ISO 16750-2 load dump; limited to low-energy ISO 7637-2 Pulse 3a/b only | Select only for cost-sensitive non-automotive industrial 12 V rails with <50 A surge exposure. |
| SMCJ17A | Same 17 V VRWM, but 1500 W PPK, SMC package (RθJC ≈ 3.5 °C/W), higher VC (27.6 V same) | Fails ISO 16750-2 Class D (requires ≥3500 W); acceptable for Class B/C load dump (≤1500 W) | Use where board space allows larger SMC footprint and thermal budget permits higher junction rise. |
Compared with SMAJ17A and SMCJ17A, DM5W17A-13 delivers 2.4× and 2.4× higher peak power respectively, with 3.2× and 3.2× lower thermal resistance-enabling single-device compliance with full automotive load dump requirements without parallel devices or heatsink augmentation.

FAQ
What is the maximum clamping voltage of DM5W17A-13 at its rated peak pulse current?
The DM5W17A-13 clamps to 27.6 V at 130 A peak pulse current (10/1000 µs waveform), as specified in the Electrical Characteristics table. This value is measured under standardized surge conditions and remains stable across its full operating temperature range (-55 °C to +175 °C), ensuring predictable protection behavior in extreme under-hood environments.
Can DM5W17A-13 be used in bidirectional surge protection configurations?
No-DM5W17A-13 is a unidirectional TVS diode with anode-heatsink polarity. It conducts only when cathode voltage exceeds anode voltage by ≥18.9 V (VBR min). For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional part like DM5W17CA-13 must be selected.
How does the DO-218 package improve thermal performance over standard SMA or SMC packages?
The DO-218 (Type E) package uses the entire heatsink tab as both electrical anode and thermal interface, achieving RθJC = 1.1 °C/W-over 3× better than SMC (3.5 °C/W) and 45× better than SMA (50 °C/W). This allows full 3600 W surge power dissipation at lower case temperatures, eliminating need for external heatsinks in most automotive PCB layouts.
Is DM5W17A-13 compliant with AEC-Q200 stress testing requirements?
Yes-DM5W17A-13 is qualified to AEC-Q200 Rev D for passive components, including temperature cycling, humidity bias, mechanical shock, and vibration tests. Its qualification is documented in Diodes' AEC-Q product definitions portal and verified through JEDEC-standard stress protocols applicable to high-reliability automotive applications.
