Product details
Overview
DM5W13AQ-13 from Diodes Incorporated is a 3600W surface-mount transient voltage suppressor (TVS) diode designed for automotive load dump and ISO 7637-2 surge protection. It features a 13 V reverse standoff voltage (VRWM), 14.4–15.9 V breakdown voltage (VBR), 21.5 V clamping voltage (VC) at 167 A peak pulse current, and AEC-Q101 qualification for under-hood power rail protection.
For engineers reviewing the DM5W13AQ-13 datasheet, DM5W13AQ-13 pinout, DM5W13AQ-13 application, or DM5W13AQ-13 equivalent, this device serves as a high-reliability, DO-218 packaged TVS for 12 V automotive systems requiring ISO 16750-2 Pulse A/B and ISO 7637-2 Pulse 1/2a/3a/3b compliance with low thermal resistance (1.1 °C/W) and high-temperature operation up to +175 °C.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to clamp transient overvoltages on DC power lines. Its DO-218 (Type E) package provides low junction-to-case thermal resistance (1.1 °C/W), enabling effective heat dissipation during 3600 W, 10/1000 µs surges.
The device exhibits 10 µA max reverse leakage at VRWM (13 V) and 150 µA at TJ = +175 °C, with clamping performance validated across temperature and waveform conditions per ISO standards. Polarity is defined by heatsink-as-anode configuration, critical for correct PCB layout and thermal management.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Lower 400 W PPK, SMA package, 27.7 V VC @ 12.3 A IPP | Not suitable for ISO 16750-2 load dump; limited to lower-energy ISO 7637-2 pulses | Select when cost sensitivity outweighs surge severity; requires additional parallel devices for 3600 W handling |
| SMCJ13A | 1500 W PPK, SMC package, 21.5 V VC @ 70 A IPP, same VBR range | Lacks AEC-Q101 qualification and IATF 16949 traceability; not PPAP-capable | Acceptable for non-safety-critical industrial 12 V rails where automotive certification is not mandated |

FAQ
What is the maximum clamping voltage of DM5W13AQ-13 at its rated peak pulse current?
The DM5W13AQ-13 has a maximum clamping voltage (VC) of 21.5 V at 167 A peak pulse current (IPP), measured using the 10/1000 µs standard waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Is DM5W13AQ-13 compatible with lead-free reflow soldering processes?
Yes, DM5W13AQ-13 uses matte tin-plated terminals compliant with J-STD-020 moisture sensitivity level 1 and qualified for lead-free reflow profiles up to 260 °C peak temperature. Its DO-218 package withstands standard Pb-free thermal cycling without delamination or bond integrity loss.
How does the heatsink-as-anode configuration affect PCB layout?
The anode is the metal heatsink tab, requiring direct connection to a large copper thermal pad for optimal RθJC (1.1 °C/W). The cathode is the bar-marked lead; incorrect orientation causes open-circuit failure. Layout must allocate ≥200 mm² exposed copper area beneath the heatsink with ≥6 thermal vias to internal ground planes.
Does DM5W13AQ-13 meet both ISO 16750-2 and ISO 7637-2 requirements?
Yes, DM5W13AQ-13 is explicitly validated for ISO 16750-2 Pulse A (slow decay) and Pulse B (fast decay), and ISO 7637-2 Pulse 1 (inductive switch-off), Pulse 2a (battery disconnect), Pulse 3a/3b (capacitive coupling). Its 3600 W rating covers the most severe ISO 16750-2 Load Dump (Pulse 5a) condition.
