Product details
Overview
DM5W10AQ-13 from Diodes Incorporated is a 3600W surface-mount transient voltage suppressor (TVS) diode designed for automotive power-line surge protection. It features a 10V reverse standoff voltage (VRWM), 11.1–12.3V breakdown voltage (VBR), 17.0V clamping voltage at 211A peak pulse current, and AEC-Q101 qualification for under-hood applications including battery rail and alternator load dump circuits.
For engineers reviewing the DM5W10AQ-13 datasheet, DM5W10AQ-13 pinout, DM5W10AQ-13 application, or DM5W10AQ-13 equivalent, this device delivers 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 - critical for robust automotive ECU and ADAS power interface design.
Technical Context
This unidirectional TVS diode operates in avalanche mode to clamp transients on DC power lines. Its DO-218 (Type E) package integrates a heatsink-connected anode for efficient thermal dissipation during 10/1000µs surges up to 3600W, with derating to 2800W above +25°C case temperature.
The device exhibits 15µA max reverse leakage at VRWM and maintains stable clamping performance across -55°C to +175°C junction temperature range. Its low RθJC (1.1°C/W) enables direct mounting to PCB copper pours or metal-core substrates for automotive-grade thermal management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Lower peak power (600W), SMB package, higher RθJA (~50°C/W), no AEC-Q101 certification | Limited to non-automotive or low-risk 12V industrial applications; unsuitable for load dump | Select only for cost-sensitive consumer electronics where ISO compliance is not required |
| SMCJ10A-Q | Same 3600W rating and AEC-Q101 qualification, but SMC package (larger footprint, higher RθJC = 1.5°C/W) | Compatible for ISO 16750-2, but requires larger PCB area and delivers ~36% less thermal efficiency than DO-218 | Choose when existing layout uses SMC footprints and thermal margin allows 0.4°C/W penalty |
Compared with SMBJ10A and SMCJ10A-Q, DM5W10AQ-13 provides superior thermal performance (1.1°C/W), smallest automotive-qualified footprint (DO-218), and guaranteed PPAP support - making it optimal for space-constrained, high-reliability automotive power interfaces.

FAQ
What is the maximum clamping voltage of DM5W10AQ-13 at rated peak pulse current?
The DM5W10AQ-13 has a maximum clamping voltage (VC) of 17.0V at 211A peak pulse current (10/1000µs waveform), measured per JEDEC standards. This value is guaranteed across the full operating temperature range (-55°C to +175°C) and defines the upper voltage limit imposed on protected circuits during surge events.
Can DM5W10AQ-13 replace SMBJ10A in an existing automotive design?
No - DM5W10AQ-13 is not a drop-in replacement for SMBJ10A due to different package (DO-218 vs. SMB), polarity orientation (heatsink = anode), and thermal pad requirements. While both suppress 10V transients, DM5W10AQ-13 delivers 6× higher peak power and AEC-Q101 qualification, necessitating PCB layout and thermal design updates.
Does DM5W10AQ-13 require external heat sinking beyond PCB copper?
No - the DO-218 package's heatsink tab is designed for direct thermal coupling to ≥100mm² of 2oz copper on the PCB. With proper layout (via-stitched thermal pads), it achieves 1.1°C/W junction-to-board thermal resistance without additional heatsinks, meeting ISO 16750-2 load dump requirements at TC ≤ +125°C.
How does the 15µA max reverse leakage at VRWM impact low-power automotive systems?
The 15µA maximum reverse leakage at 10V VRWM and +25°C adds negligible current draw - less than 0.15mW static power loss - making DM5W10AQ-13 suitable for always-on automotive modules like telematics and remote keyless entry receivers where standby current budgets are tight (<100µA).
