Product details
Overview
DM6W36AQ-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode in DO-218 (Type E) package, designed for automotive load-dump and ISO7637-2 surge protection. It features 4600W peak pulse power (10/1000µs), 36V reverse standoff voltage (VRWM), 58.1V clamping voltage at 79A peak pulse current, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the DM6W36AQ-13 datasheet, DM6W36AQ-13 pinout, DM6W36AQ-13 application, or DM6W36AQ-13 equivalent, key selection criteria include clamping performance under ISO16750-2 Pulse 5a, thermal resistance (RθJC = 1.0°C/W), anode-heatsink polarity configuration, and compliance with automotive change control and PPAP requirements.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped crowbar device during transients, with breakdown voltage VBR = 40.0–44.2V at 5mA test current and low thermal resistance enabling high-power dissipation directly into the heatsink. Its DO-218 package integrates the anode terminal into the metal slug for optimal thermal path.
The device meets ISO16750-2 Pulse 5a (load dump) and ISO7637-2 Pulse 1, 2a, 3a, 3b waveforms, with 150µA max reverse leakage at VRWM and 250µA at TJ = +175°C - critical for long-term reliability in high-temperature engine compartments.

|---|---|
| Peak Pulse Power | 4600W (10/1000µs waveform; enables robust load-dump suppression without failure) |
| Reverse Standoff Voltage | 36V (stable blocking up to battery overvoltage threshold; avoids false triggering) |
| Clamping Voltage | 58.1V @ 79A (limits downstream IC stress during 10/1000µs surge events) |
| Junction-to-Case Thermal Resistance | 1.0°C/W (supports continuous 6W average power at TC = +25°C with minimal temperature rise) |
| Operating Temperature Range | −55°C to +175°C (validated for under-hood placement near engines or power electronics) |
| AEC-Q101 Qualified | Yes (certified for automotive use with PPAP capability and IATF 16949 manufacturing) |

|---|---|
Use Scenario: Protects microcontroller power supply against alternator load-dump surges up to 35V sustained and 60V transient spikes. IC Role / Device Role: Primary clamping element placed between battery feed and DC-DC input stage. Use Value: Limits voltage seen by LDOs and PMICs to ≤58.1V, preventing latch-up or gate oxide damage in 40V-rated input stages. |
Use Scenario: Shields LIN/CAN transceivers and power switches from ISO7637-2 Pulse 1 (inductive switch-off) and Pulse 3b (capacitive coupling). IC Role / Device Role: Unidirectional surge shunt on main 12V distribution rail upstream of local regulators. Use Value: Maintains rail integrity below 60V during 100ns–100ms transients, ensuring uninterrupted communication and actuator control. |

IC Role / Device Role: High-energy clamp across motor power rails (VDD and GND) with heatsink-integrated anode. Use Value: Absorbs >4kW pulses without derating at +150°C case temperature, preserving driver FET reliability. |
Use Scenario: Secures 5V/3.3V camera module power derived from buck converter fed by vehicle battery. IC Role / Device Role: Secondary-level TVS on converter output, coordinated with primary DM6W36AQ-13 on input. Use Value: Prevents pixel corruption or sensor reset by limiting transient overshoot to <10% of nominal rail voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-Q | Lower peak power (400W), SMA package, RθJC ≈ 40°C/W | Not suitable for load-dump; limited to ISO7637-2 Pulse 1/2/3 only | Select when space-constrained and surge energy <100mJ; requires external heatsinking |
| SMCJ36A-Q | Same 36V VRWM, 4000W peak power, but SMC package with RθJC ≈ 2.5°C/W | Lacks AEC-Q101 certification and PPAP support; not qualified for safety-critical modules | Use for non-automotive industrial 12V systems where qualification is not mandated |
Compared with SMAJ36A-Q and SMCJ36A-Q, DM6W36AQ-13 delivers 15% higher peak power, 2.5× lower thermal resistance, and full automotive qualification - making it the only choice for AEC-compliant load-dump protection in ECUs and ADAS domains.

FAQ
What is the maximum clamping voltage of DM6W36AQ-13 at rated peak pulse current?
The clamping voltage VC is 58.1V at IPP = 79A for a 10/1000µs waveform, measured per IEC 61000-4-5. This value ensures protected downstream ICs experience no more than 58.1V during worst-case load-dump events, well within safe operating limits of 40V-input PMICs and microcontrollers.
How is thermal management implemented in the DO-218 package?
The DO-218 (Type E) package uses the anode as the integral metal heatsink slug, providing direct thermal conduction from junction to PCB copper pour or chassis. With RθJC = 1.0°C/W and PM(AV) = 6W at TC = +25°C, effective heatsinking allows operation at +150°C case temperature without derating.
Does DM6W36AQ-13 meet ISO16750-2 Pulse 5a requirements?
Yes - DM6W36AQ-13 is explicitly validated for ISO16750-2 Pulse 5a (load dump), delivering 4600W peak power at 10/1000µs and sustaining 35V for 400ms. Its 36V VRWM and 58.1V VC ensure compliance while maintaining margin against battery overvoltage thresholds.
Is lead-free and halogen-free compliance documented for this part?
Yes - DM6W36AQ-13 carries RoHS 3 (2015/863/EU) compliance with all applicable exemptions, plus Diodes' "Green" certification: <900ppm bromine/chlorine (total Br+Cl <1500ppm) and <1000ppm antimony. Matte tin plating meets MIL-STD-202 solderability standards.
