Product details
Overview
DM5W15AQ-13 from Diodes Incorporated is a 3600W surface-mount transient voltage suppressor (TVS) diode designed for automotive power rail protection. It features a 15V reverse standoff voltage (VRWM), 16.7–18.5V breakdown voltage (VBR), and clamps transients to ≤24.2V at 148A peak pulse current (10/1000µs), meeting ISO16750-2 Load Dump and ISO7637-2 Pulse 1/2a/3a/3b surge requirements in engine control units and body electronics.
For engineers reviewing the DM5W15AQ-13 datasheet, DM5W15AQ-13 pinout, DM5W15AQ-13 application, or DM5W15AQ-13 equivalent, this AEC-Q101 qualified DO-218 TVS delivers verified 3600W peak pulse power, low thermal resistance (RθJC = 1.1°C/W), and high-temperature operation up to +175°C - critical for under-hood automotive surge immunity design.
Technical Context
This unidirectional TVS operates with anode-connected heatsink polarity and is optimized for fast clamping of high-energy load dump surges (10ms exponential waveform) and repetitive transients per automotive standards. Its low 1.1°C/W junction-to-case thermal resistance enables sustained 5W average power dissipation at TC = +25°C while maintaining stable VBR and VC across -55°C to +175°C.
The device uses silicon avalanche technology with tight VBR tolerance (±5% typical), <10µA IR at VRWM, and exhibits minimal capacitance (<36pF at 1MHz, per DM5W36AQ data), ensuring minimal signal distortion in DC power line protection applications without affecting system EMI behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3600W (10/1000µs waveform): sustains single-event surges up to ISO16750-2 Load Dump level IV without failure |
| Reverse Standoff Voltage | 15V: blocks normal 12V/24V automotive battery operation while triggering only during overvoltage events |
| Breakdown Voltage | 16.7–18.5V @ 5mA: precise avalanche onset ensures predictable clamping threshold with ±5% distribution |
| Clamping Voltage | ≤24.2V @ 148A: limits downstream IC voltage stress to safe levels during worst-case 3600W surge |
| Junction-to-Case Thermal Resistance | 1.1°C/W: enables efficient heat transfer to PCB copper or heatsink, supporting continuous 5W operation at TC = +25°C |
| Operating Temperature | -55°C to +175°C: validated for under-hood placement in engine control modules and transmission ECUs |
| AEC-Q101 Qualified | Yes: qualified for automotive use with PPAP capability and IATF 16949 manufacturing compliance |
Pinout & Package
Package: DO-218 (Type E) molded plastic case with matte tin-plated terminals; heatsink tab is electrically connected to the anode. Polarity marked by cathode bar on package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Positive terminal / thermal path | Must be soldered to ≥100mm² copper pour for effective heat dissipation and electrical connection to system ground or supply return |
| Cathode (Top Surface Lead) | Negative terminal / surge input | Connected to protected line (e.g., battery feed); clamps positive transients to anode potential during avalanche conduction |
Key Features
| Feature | Design Value |
|---|---|
| 3600W Peak Pulse Power | Enables single-device protection against ISO16750-2 Load Dump (up to 35V, 10ms) without series impedance or staged clamping |
| Low RθJC (1.1°C/W) | Reduces junction temperature rise by >40% vs. comparable DO-214AB TVS, extending reliability in high-ambient under-hood environments |
| AEC-Q101 Qualification | Validates robustness for automotive production use, including temperature cycling, humidity testing, and mechanical shock per qualification plan |
| RoHS & Halogen-Free | Meets EU RoHS 3 (2015/863/EU) and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb), supporting eco-compliance programs |
| ISO7637-2 / ISO16750-2 Compliance | Guarantees pass/fail validation against standardized automotive surge waveforms - eliminates need for external test verification |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) Battery Feed |
|---|---|
Use Scenario: Protects microcontroller power rails from load dump surges during alternator regulation failure in gasoline/diesel engines. IC Role / Device Role / Timing Role: Unidirectional TVS clamps positive transients on 12V main supply line before LDO regulators and MCU VDD pins.

Use Scenario: Shields CAN/LIN transceivers and door module drivers from ISO7637-2 Pulse 1 (inductive switch-off) and Pulse 3b (capacitive coupling) transients. IC Role / Device Role / Timing Role: Fast-response surge absorber placed at BCM main connector entry point, upstream of DC-DC converters. Use Value: Maintains communication integrity by suppressing sub-100ns transients without adding signal path capacitance (>36pF). |
| Transmission Control Module (TCM) | Advanced Driver Assistance Systems (ADAS) Camera Power |
Use Scenario: Safeguards solenoid driver ICs and position sensor interfaces from battery reversal and jump-start induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24V auxiliary rail, coordinated with fuse and reverse-polarity MOSFET protection. Use Value: Enables TCM operation at +175°C ambient via low RθJC and high-temperature-stable VBR, reducing thermal derating needs. |
Use Scenario: Secures 12V camera module input against ignition noise and alternator ripple spikes in rear-view and surround-view systems. IC Role / Device Role / Timing Role: Low-leakage (≤10µA @ 15V) TVS placed directly at camera connector to minimize PCB trace inductance impact. Use Value: Eliminates image artifacts caused by transient-induced supply droop, preserving ADC reference stability and pixel clock accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Lower peak power (400W), DO-214AC package, RθJC ≈ 50°C/W | Not suitable for Load Dump; limited to ISO7637-2 Pulse 1/2a only | Select only for cost-sensitive non-load-dump applications where board space is constrained and thermal budget allows higher junction temp |
| SMCJ15A | 1500W peak power, DO-214AB package, RθJC ≈ 10°C/W, same VRWM | Passes ISO7637-2 but fails ISO16750-2 Load Dump due to insufficient energy handling | Use where moderate surge immunity suffices and DO-218 mounting is not feasible; requires larger copper area for thermal management |
Compared with SMAJ15A and SMCJ15A, DM5W15AQ-13 uniquely supports full automotive load dump immunity in a surface-mount package with superior thermal performance - enabling single-device protection where legacy solutions require cascaded TVS or hybrid RC networks.

FAQ
What is the maximum clamping voltage of DM5W15AQ-13 at rated peak current?
The maximum clamping voltage (VC) is 24.2V when subjected to a 148A peak pulse current with a 10/1000µs waveform. This value is guaranteed across the full operating temperature range (-55°C to +175°C) and ensures downstream circuitry remains within safe voltage limits during surge events.
Can DM5W15AQ-13 be used in 24V commercial vehicle systems?
Yes - its 15V VRWM and 24.2V clamping voltage make it suitable for 24V nominal systems. The device meets ISO16750-2 Load Dump requirements up to 35V, and its +175°C max junction temperature supports under-hood deployment in trucks and buses where ambient temperatures exceed 125°C.
How does the DO-218 package improve thermal performance over DO-214AB?
The DO-218 (Type E) package provides a direct metal heatsink tab that achieves 1.1°C/W junction-to-case thermal resistance - ~90% lower than typical DO-214AB devices (~10°C/W). This allows the DM5W15AQ-13 to dissipate 3600W surges without exceeding safe junction temperatures when mounted on ≥100mm² copper.
Is DM5W15AQ-13 compatible with lead-free reflow soldering processes?
Yes - it features matte tin-plated terminals qualified to MIL-STD-202, Method 208, and supports standard lead-free reflow profiles (peak temperature up to 260°C). Moisture sensitivity level is rated at Level 1 per J-STD-020, eliminating bake requirements prior to assembly.
