Product details
Overview
DM6W24A-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode designed for automotive load dump and ISO7637-2 surge protection. It features a 24 V reverse standoff voltage (VRWM), 38.9 V maximum clamping voltage (VC) at 118 A peak pulse current (IPP), and 4600 W peak pulse power dissipation (10/1000 µs waveform), housed in a DO-218 (Type E) package with anode-heatsink polarity. It is qualified to AEC-Q standards and used in 12 V automotive power rail protection.
For engineers reviewing the DM6W24A-13 datasheet, DM6W24A-13 pinout, DM6W24A-13 application, or DM6W24A-13 equivalent, this page provides verified electrical parameters, thermal resistance (RθJC = 1.0 °C/W), ISO16750-2 compliance status, DO-218 mechanical dimensions, and validated automotive-grade alternatives - all critical for robust power rail transient design.
Technical Context
This unidirectional TVS diode operates as a clamping device across DC power lines, activating when reverse voltage exceeds 24 V VRWM to divert surge energy away from downstream circuitry. Its low clamping ratio (VC/VRWM ≈ 1.62) and high IFSM rating (600 A) support robust handling of 8.3 ms load dump transients per ISO16750-2.
The DO-218 package enables direct heatsink mounting via the anode terminal, delivering 1.0 °C/W junction-to-case thermal resistance and enabling stable 6 W steady-state power dissipation at TC = +25°C. Its operation is specified from –55°C to +175°C, supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system overvoltage trip threshold. |
| VBR (min/max) | 26.7 V / 29.5 V - Breakdown occurs within this range at 5 mA test current; defines activation onset tolerance band. |
| VC @ IPP | 38.9 V @ 118 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on protected ICs. |
| PPK | 4600 W - Peak non-repetitive surge power handling capability; validates compliance with ISO7637-2 Pulse 5a. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables accurate thermal design when mounted to heatsink. |
| TJ Range | –55°C to +175°C - Operating junction temperature range; supports engine compartment deployment without derating. |
| IFSM | 600 A - Peak forward surge current (8.3 ms half-sine); ensures survivability during battery disconnection events. |
Pinout & Package
Package: DO-218 (Type E), surface-mount, anode-heatsink configuration. Polarity indicated by bar (cathode) and circle (anode) markings; heatsink terminal is electrically connected to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Current entry point during clamping; thermally coupled to PCB/heatsink | Primary thermal path - must be soldered to large copper area or external heatsink for RθJC = 1.0 °C/W performance. |
| Cathode (Bar-marked lead) | Current exit point during clamping; connected to protected line | Reverse-biased connection to 12 V rail; clamps to 38.9 V when surge exceeds 24 V VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| 4600 W peak pulse power | Validates compliance with ISO7637-2 Pulse 5a (load dump) and ISO16750-2 Category C5 requirements. |
| Low clamping voltage (38.9 V) | Keeps protected 12 V system components (e.g., MCU power supplies) below absolute maximum ratings during surges. |
| 1.0 °C/W thermal resistance | Enables reliable 6 W steady-state dissipation with minimal temperature rise when properly heatsinked. |
| AEC-Q qualified | Meets automotive reliability standards for temperature cycling, humidity, and long-term stability in harsh environments. |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) Supply Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | Lower PPK (400 W), SMA package, RθJC ≈ 50 °C/W, no AEC-Q qualification | Not suitable for load dump; limited to ISO7637-2 Pulse 1/2/3 only | Select only for cost-sensitive non-automotive 12 V systems with lower surge exposure. |
| DM6W24AQ-13 | Identical electrical specs; AEC-Q200 Grade 1 qualified (–40°C to +125°C ambient), automotive-specific traceability | Required for OEM production programs mandating full automotive qualification documentation | Choose for Tier 1 automotive designs requiring PPAP, lot traceability, and extended reliability testing. |
Compared with SMAJ24A, DM6W24A-13 delivers 11.5× higher surge power and integrated heatsinking; versus DM6W24AQ-13, it trades automotive certification for broader commercial/industrial use with identical clamping and thermal performance.

FAQ
What is the maximum clamping voltage of DM6W24A-13 at its rated peak pulse current?
The DM6W24A-13 clamps to a maximum of 38.9 V when subjected to its rated 118 A peak pulse current (10/1000 µs waveform), as specified in the Electrical Characteristics table. This value is measured at TA = +25°C and defines the upper voltage limit imposed on protected circuitry during surge events.
Can DM6W24A-13 be used in place of DM6W24AQ-13 in automotive production?
DM6W24A-13 is not AEC-Q200 qualified and lacks automotive-specific traceability and test reporting. While electrically identical, it does not meet OEM requirements for production automotive use where DM6W24AQ-13 is mandated. Use only DM6W24AQ-13 for PPAP-submission or Tier 1 production programs.
How should the DO-218 package be thermally managed on PCB?
The anode tab (heatsink terminal) must be soldered to a minimum 250 mm² copper pad with ≥4 thermal vias (0.3 mm diameter) to an internal ground plane. Per datasheet Fig. 1, derating begins above TC = +25°C; at TC = +100°C, PM(AV) drops to ~3.5 W.
Does DM6W24A-13 meet ISO10605 ESD requirements?
Yes - the DM6W24A-13 complies with ISO10605 Pulse A and Pulse B for ESD immunity, as stated in the Product Summary. Its low clamping voltage and fast response (<1 ns typical) enable effective suppression of ±25 kV contact and ±30 kV air discharge events per ISO10605 test setup.
