Product details
Overview
DM6W36A-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 at 10/1000µs, features a 36V reverse standoff voltage (VRWM), clamps to ≤58.1V at 79A peak current, and operates from –55°C to +175°C for under-hood applications.
For engineers reviewing the DM6W36A-13 datasheet, DM6W36A-13 pinout, DM6W36A-13 application, or DM6W36A-13 equivalent, key selection criteria include clamping voltage vs. system rail margin, thermal resistance (RθJC = 1.0°C/W), DO-218 package mounting compatibility, and compliance with ISO16750-2 load dump and ISO7637-2 Pulse 1/2a/3a/3b waveforms.
Technical Context
This unidirectional TVS diode uses an avalanche breakdown structure optimized for high-energy transients. Its low thermal resistance (1.0°C/W junction-to-case) enables direct heatsink mounting via the anode terminal, supporting sustained power dissipation up to 6W at TC = +25°C and derated operation up to +175°C junction temperature.
The device meets AEC-Q200 stress test requirements for automotive reliability and exhibits <10µA reverse leakage at VRWM (36V) and only 150µA at TJ = +175°C - critical for low-quiescent-current battery-connected circuits. Clamping performance is specified across 10/1000µs and 10/10000µs waveforms per IEC 61000-4-5.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | Lower PPK (400W), SMA package, RθJC ≈ 50°C/W, no AEC-Q200 qualification | Suitable for non-automotive industrial controls; insufficient for ISO16750-2 load dump | Select when cost sensitivity outweighs automotive surge compliance and thermal performance. |
| SMCJ36A | PPK = 1500W, SMC package, RθJC ≈ 10°C/W, AEC-Q200 optional (not standard) | Meets ISO7637-2 Pulse 1/2a but not full load dump; limited to lower-power ECUs | Choose where space allows larger SMC footprint and 1500W clamping suffices for system-level testing. |
Compared with SMAJ36A and SMCJ36A, DM6W36A-13 provides 3× higher peak power handling, 50× lower thermal resistance, and guaranteed AEC-Q200 qualification - making it the only option rated for under-hood load dump protection in production automotive modules.

FAQ
What is the maximum clamping voltage of DM6W36A-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 58.1V at 79A peak pulse current under the 10/1000µs waveform, measured per IEC 61000-4-5. This value is guaranteed across the full operating temperature range (–55°C to +175°C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Can DM6W36A-13 be used in bidirectional surge protection configurations?
No - DM6W36A-13 is a unidirectional TVS diode with anode-heatsink polarity. Its breakdown occurs only in reverse bias. For bidirectional protection (e.g., data lines), a symmetric pair or dedicated bidirectional TVS like DM6W36CA must be used; this part lacks forward conduction capability for negative transients.
How does the DO-218 package improve thermal performance versus SMA or SMB packages?
The DO-218 (Type E) package features a large exposed anode pad that serves as both electrical terminal and thermal interface. With RθJC = 1.0°C/W - compared to ~50°C/W for SMAJ36A - it transfers heat directly to PCB copper or heatsinks, enabling continuous 6W dissipation and sustaining 4600W pulses without thermal runaway.
Is there an automotive-qualified version of DM6W36A-13 with extended test documentation?
Yes - the DM6W36AQ-13 is the AEC-Q200-qualified variant, documented in a separate datasheet (DS40427Q). It undergoes additional stress testing including temperature cycling, high-temperature operating life, and board-level vibration, with full PPAP documentation available for Tier 1 automotive programs.
