Product details
Overview
DM5W10A-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode designed for automotive power-line surge protection. It delivers 3600W peak pulse power (10/1000µs), clamps at 17.0V max under 211A peak current, and features a 10V reverse standoff voltage - enabling robust protection of 12V automotive ECUs against ISO7637-2 Pulse 1/2a/3a/3b and ISO16750-2 load dump surges.
For engineers reviewing the DM5W10A-13 datasheet, DM5W10A-13 pinout, DM5W10A-13 application, or DM5W10A-13 equivalent, key selection criteria include its DO-218 package thermal performance (RθJC = 1.1°C/W), low 15µA reverse leakage at VRWM, AEC-Q qualified reliability, and explicit compliance with ISO10605 Pulse A/B ESD immunity.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to clamp transient overvoltages on automotive battery rails. Its 10V VRWM aligns with nominal 12V system operation, while the 11.1–12.3V VBR range ensures precise turn-on before downstream component damage. The device sustains 500A non-repetitive forward surge current (8.3ms half-sine) and maintains stable clamping up to +175°C junction temperature.
Thermal design is enabled by its low 1.1°C/W junction-to-case resistance and 2.74g molded plastic DO-218 (Type E) package. Polarity is marked with cathode bar; heatsink side is anode. It supports high-reliability automotive deployment per JEDEC standards and meets RoHS 3, halogen-free, and antimony-free "Green" requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3600W (10/1000µs waveform): absorbs severe load dump transients without failure |
| Reverse Standoff Voltage | 10V: blocks normal 12V rail voltage while remaining fully inactive during steady-state operation |
| Clamping Voltage | 17.0V @ 211A: limits voltage seen by protected ICs to safe levels during surge events |
| Junction-to-Case Thermal Resistance | 1.1°C/W: enables efficient heat transfer to PCB copper or heatsink for sustained 5W average power dissipation |
| Operating Temperature Range | −55°C to +175°C: supports under-hood placement in engine control modules and body electronics |
| Surge Standards Compliance | ISO7637-2 (Pulse 1, 2a, 3a, 3b) & ISO16750-2: validated for automotive-grade surge immunity testing |
Pinout & Package
Package: DO-218 (Type E), surface-mount molded plastic case with UL 94V-0 flammability rating, matte tin-plated terminals, and polarity indicated by cathode bar marking. Heatsink side is anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Side) | Current Entry Point During Clamping | Connected to protected circuit ground or low-side return path; serves as primary thermal interface |
| Cathode (Marked Side) | Current Exit Point During Clamping | Connected to protected line (e.g., battery rail); voltage clamping occurs between cathode and anode |
Key Features
| Feature | Design Value |
|---|---|
| High Peak Pulse Power | 3600W capability enables single-device protection against worst-case ISO16750-2 load dump (up to 35V, 10ms exponential) |
| Low Thermal Resistance | RθJC = 1.1°C/W allows direct mounting to large copper areas for reliable 5W continuous power handling |
| Automotive Qualification | AEC-Q qualified per JEDEC standards - verified for high-reliability use in safety-critical vehicle subsystems |
| Environmental Compliance | RoHS 3 compliant, halogen- and antimony-free "Green" construction (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) Battery Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower 400W peak power; SMA package (RθJC ≈ 35°C/W); 17.1V clamping @ 24.4A | Rated for industrial/commercial use only; not AEC-Q qualified or ISO16750-2 validated | Select when cost sensitivity outweighs automotive qualification and surge margin requirements |
| SMCJ10A | 1500W peak power; SMC package (RθJC ≈ 10°C/W); 17.0V clamping @ 88.2A | Lacks ISO16750-2 load dump validation; limited to ISO7637-2 Pulse 1/2a only | Choose for non-load-dump automotive sub-systems (e.g., infotainment) where space permits larger SMC footprint |
Compared with SMAJ10A and SMCJ10A, DM5W10A-13 provides 2.4× higher surge energy absorption than SMCJ10A and 9× more than SMAJ10A, while delivering automotive-grade thermal robustness and full ISO16750-2 compliance - critical for engine bay and safety-related power domains.

FAQ
What is the maximum clamping voltage of DM5W10A-13 under rated surge conditions?
The DM5W10A-13 exhibits a maximum clamping voltage of 17.0V when subjected to a 10/1000µs waveform with a peak current of 211A. This value is guaranteed across the full operating temperature range (−55°C to +175°C) and ensures downstream components remain within safe voltage tolerances during ISO-defined transients.
Does DM5W10A-13 require external series impedance for effective protection?
No external series impedance is required for basic surge clamping functionality. The device is designed for direct connection across protected lines and ground. However, for ESD-sensitive interfaces (e.g., LIN or CAN), a small series resistor (10–100Ω) may be added to limit di/dt and improve system-level immunity without compromising clamping performance.
How does the DO-218 package enhance thermal performance compared to SMA or SMC packages?
The DO-218 (Type E) package features a large metalized heatsink surface on the anode side, achieving RθJC = 1.1°C/W - over 30× better than SMA and ~9× better than SMC. This enables direct thermal coupling to PCB copper pours or external heatsinks, sustaining 5W average power dissipation without derating at +125°C case temperature.
Is DM5W10A-13 compatible with lead-free reflow soldering processes?
Yes. DM5W10A-13 uses matte tin-plated terminals and is qualified for standard Pb-free reflow profiles (J-STD-020 Level 1). Its molded plastic body meets UL 94V-0 flammability rating, and moisture sensitivity level is rated at MSL 1 - permitting unlimited floor life and compatibility with standard high-volume SMT assembly lines.
