Product details
Overview
DM6W30A-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode designed for automotive load dump and ISO7637-2 surge protection in 12V/24V systems. It delivers 4600W peak pulse power (10/1000µs), clamps at 48.4V max under 95A peak current, and features a 30V reverse standoff voltage with low thermal resistance (1.0°C/W junction-to-case).
For engineers reviewing the DM6W30A-13 datasheet, DM6W30A-13 pinout, DM6W30A-13 application, or DM6W30A-13 equivalent, key selection criteria include ISO16750-2 compliance, DO-218 package thermal performance, 175°C operating temperature capability, and verified clamping behavior under 8.3ms load dump waveforms.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device with anode-connected heatsink configuration. Its breakdown voltage is specified at 33.3–36.8V (min/max) with 5mA test current, and it maintains ≤10µA reverse leakage at 30V standoff up to +175°C.
The device uses a robust silicon junction optimized for high-energy transients: it sustains 600A non-repetitive forward surge current (8.3ms half-sine), exhibits 2.74g mass for mechanical stability, and achieves 48.4V clamping at 95A - enabling reliable protection of CAN, LIN, and power supply rails in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 4600W (10/1000µs waveform): handles full ISO16750-2 load dump surges without failure |
| Reverse Standoff Voltage | 30V: compatible with 24V nominal automotive systems while avoiding false triggering |
| Clamping Voltage | 48.4V @ 95A: limits downstream voltage to safe levels for 3.3V/5V/12V ICs and microcontrollers |
| Junction-to-Case Thermal Resistance | 1.0°C/W: enables efficient heat transfer to PCB copper or heatsink, critical for sustained surge duty |
| Operating Temperature Range | −55°C to +175°C: qualified for under-hood engine control unit (ECU) and transmission control module (TCM) placement |
| Surge Standards Compliance | ISO 7637-2 (Pulse 1, 2a, 3a, 3b) and ISO 16750-2: meets OEM-level automotive immunity requirements |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Current entry point during clamping | Must be soldered to large copper pour or external heatsink for thermal management and surge current path |
| Cathode (Marked Lead) | Current exit point during clamping | Connected to protected line (e.g., battery rail); polarity-sensitive installation required |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Protects 12V power input against alternator load dump surges during battery disconnect events. IC Role / Device Role / Timing Role: Shunt-clamping TVS placed directly at ECU power entry point before DC-DC converter.

IC Role / Device Role / Timing Role: Secondary surge suppression stage after front-end fuse and primary TVS. Use Value: 4600W peak power rating ensures margin against worst-case 10/1000µs transients in ASIL-B power domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Lower peak power (400W), SMA package, RθJC ≈ 50°C/W | Not suitable for load dump; limited to ISO7637-2 Pulse 1/2a only | Select when space-constrained and surge energy is below 100mJ |
| SMCJ30A | Same DO-214AB package, 1500W peak power, higher clamping (48.4V → 49.9V) | Lacks ISO16750-2 validation; not AEC-Q200 qualified | Acceptable for industrial 24V systems where automotive certification is not required |
Compared with SMAJ30A and SMCJ30A, DM6W30A-13 provides 3× higher surge power handling, certified automotive qualification, and superior thermal performance - making it the only option among the three validated for under-hood load dump protection per ISO16750-2.

FAQ
What is the maximum clamping voltage of DM6W30A-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 48.4V at 95A peak pulse current under the 10/1000µs waveform condition. This value is measured per the test method defined in DS40427 Rev. 6–2, ensuring consistent verification across production lots and enabling accurate downstream circuit protection margining.
Is DM6W30A-13 suitable for bidirectional surge protection?
No - DM6W30A-13 is a unidirectional TVS diode with anode-connected heatsink and cathode-marked lead. It protects only against positive transients on the cathode side. For bidirectional protection (e.g., data lines), a dedicated bidirectional TVS like DM5W30A must be used instead.
How does the DO-218 package improve thermal performance compared to SMA or SMB packages?
The DO-218 (Type E) package features a large metal heatsink tab directly bonded to the silicon die, achieving 1.0°C/W junction-to-case thermal resistance - over 40× better than SMAJ30A's ~50°C/W. This allows sustained power dissipation and prevents thermal runaway during repetitive surge events.
Does DM6W30A-13 meet AEC-Q200 requirements for automotive use?
Yes - DM6W30A-13 is qualified to JEDEC standards referenced in AEC-Q200 for high-reliability automotive applications. It undergoes temperature cycling, humidity bias, and surge endurance testing per the standard, and is listed as automotive-compliant in Diodes' product definitions portal.
